1. Introduction<br />
1.1. Queensberry Real Estate LLP (hereafter referred to as the ‘Applicant’) is seeking full planning<br />
permission for the development of approximately 4ha of land known as Friars Walk, Newport<br />
(hereafter the ‘Site’), bounded by the Kingsway Shopping Centre to the south, existing retail units<br />
to the north and west, and Kingsway to the east. The Site is centred on National Grid Reference<br />
831273, 188005. A plan showing the location of the Site is shown on Figure 1.1.<br />
1.2. The application comprises demolition of the existing buildings and bus station and construction of<br />
new retail and leisure uses, together with a reconfigured bus station. Improvements are also<br />
proposed to the public realm which would include the provision of a new public square (Usk<br />
Plaza) and a reconfigured and enhanced John Frost Square. The Site Location Plan on Figure<br />
1.2, setting out the extent of the works..<br />
1.3. The Site comprises almost entirely of buildings and hardstanding, there are small areas of soft<br />
landscaping. The Site currently comprises a disused multi-storey car park, dated retail units,<br />
public open space within John Frost Square and Newport bus station. The buildings are typically<br />
in poor condition, resulting in a low quality public realm. The layout is imposed onto the existing<br />
street pattern and, owing to the change of grade across the Site, this results in poor permeability<br />
and accessibility, particularly for cyclists and the disabled.<br />
Development Context<br />
1.4. The Site is included in the Newport Unitary Development Plan as a site where mixed use<br />
development would be acceptable. The planning policy has been substantiated by previous<br />
applications relating to the Site.<br />
1.5. The Newport City Council Unitary Development Plan 1996-2011 1 (the UDP) identifies the<br />
redevelopment of the John Front Square area as:<br />
“a significant element of the strategy to enhance the city centre, which will be carried forward in<br />
the City Centre Masterplan.”<br />
1.6. Further to the UDP, the Site is identified as a Priority Action Area - Commercial Core, within the<br />
Newport City Centre Master Plan – Draft Supplementary Planning Guidance 2 :<br />
“Redevelopment of the Kingsway Centre will provide a southern location for a new retail anchor,<br />
whilst consolidation of the bus operations and the redevelopment of John Frost Square will<br />
provide another opportunity in a more central location. An anchor store in this location would<br />
have a positive impact on the Kingsway Boulevard.”<br />
1.7. John Frost Square is also identified within the Newport City Centre Master Plan for improvement<br />
and connection to existing and new public open spaces.<br />
1.8. Detailed consent for a retail development comprising a new bus station, covered retail shopping<br />
centre of approximately 25,500m 2 of retail space including a department store, car park for 1,000<br />
cars, basement servicing and ancillary accommodation was previously granted in 1989<br />
(application 1/17392). An application for redevelopment of the bus station was granted in 1993<br />
(application 92/0887).<br />
1.9. A second significant mixed use application was submitted, both for the Site and adjacent<br />
Kingsway Shopping Centre in 2002, on behalf of Rhys Newport Limited. The Council resolved to<br />
approve the application subject to a Section 106 Agreement but the permission was never<br />
implemented.<br />
Friars Walk, Newport<br />

1.10. Planning consent was granted to UBS Global Asset Management Limited in January 2006, for<br />
alterations and extensions to the adjoining Kingsway Shopping Centre, and erection of a 9 level<br />
multi-storey car park and associated works within the Site.<br />
1.11. Two major planning applications have been submitted for the site, relating to the redevelopment<br />
of the city centre area for mixed commercial, retail and residential use. The first of these was<br />
submitted in 2005 (Application Reference: 05/1474), while the second, an amendment to the first<br />
was submitted in 2008 (Application Reference: 08/0201). Both applications were granted with<br />
conditions.<br />
Proposed Development<br />
1.12. The application comprises demolition of the existing buildings and bus station and construction of<br />
new retail and leisure uses, together with a reconfigured bus station. Improvements are also<br />
proposed to the public realm which would include the provision of a new public square and a<br />
reconfigured and enhanced John Frost Square. A full description of the Development is provided<br />
in Chapter 5: The Development. However, the planning application form defines the<br />
Developments as follows:<br />
“Demolition and mixed use development including retail (A1), leisure / cinema (D2), cafes<br />
/ restaurants (A3), extension to existing public house (A4), associated car parking, new<br />
bus station, landscaping and access”<br />
1.13. The proposed Development seeks to integrate with the recent Kingsway / Usk Way boulevard<br />
project, and form a new high quality, accessible link from Commercial Street to the River Usk and<br />
the Newport City Footbridge. A conservation area application is also being submitted owing to the<br />
Site’s location within the Town Centre Conservation Area (TCCA). The western extent of the<br />
TCCA boundary is set out on Figures 1.3.<br />
1.14. The sequencing of the construction works on site is affected by the significant services diversion<br />
works that need to be undertaken, bus station works and the demolition and excavation works<br />
that need to be carried out. Where possible the events of demolition, diversion and construction<br />
would occur concurrently on site to minimise the overall project programme.<br />
<strong>Environmental</strong> Impact Assessment<br />
1.15. <strong>Environmental</strong> Impact Assessment (EIA) is a process that must be followed for certain types of<br />
development before a decision is made on whether planning permission should be granted. The<br />
Applicant recognises that the planning application falls within Schedule 2, Category 10(b) of the<br />
Town and Country Planning (<strong>Environmental</strong> Impact Assessment) (England and Wales)<br />
Regulations 1999 (as amended) 3 (hereafter referred to as the ‘EIA Regulations’) in that:<br />
It constitutes development pursuant to Category 10(b) (Urban Development Projects) of<br />
Schedule 2 of the EIA Regulations;<br />
The Site is in excess of the 0.5 hectare threshold; and<br />
The Development is likely to have significant effects on the environment by virtue of factors<br />
such as its nature, size or location.<br />
1.16. The Applicant therefore commissioned an EIA for the Development, the findings of which are<br />
presented within this <strong>Environmental</strong> <strong>Statement</strong> (ES) which accompanies the planning application.<br />
The planning application has been submitted to and, would be, determined by Newport City<br />
Friars Walk, Newport<br />

Council (NCC), taking into account the likely environmental effects of the Development reported<br />
herein.<br />
1.17. In accordance with the EIA Regulations, this ES considers the likely significant effects of the<br />
Development during demolition and construction, and following completion, that is, once<br />
occupied. Where the potential for significant adverse effects on the environment have been<br />
identified, the ES sets out ways to prevent, reduce and, where possible, offset these effects.<br />
These are known as ‘mitigation measures’. Further information on how the scope of the EIA was<br />
defined and the structure of this ES is provided below and in Chapter 2: EIA Methodology.<br />

2. EIA Methodology<br />
Introduction<br />
2.1. This Chapter sets out the methodology for undertaking the EIA. Firstly, this Chapter describes the<br />
legislative framework within which the EIA has been undertaken and identifies key guidance.<br />
Secondly, the scoping process of the EIA is described explaining how environmental topics were<br />
identified for inclusion in the ES. Thirdly, the overall methodology of the EIA is described. More<br />
detailed methodologies are described for each of the specific topics that are assessed in Chapters<br />
7-17.<br />
General Approach<br />
2.2. The ES was prepared to comply with the Town and Country Planning (<strong>Environmental</strong> Impact<br />
Assessment) Regulations 1999 (as amended) 1 which implement the European Commission<br />
Directive No. 85/337/EEC 2 , as amended by Council Directive No. 97/11/EC 3 . Specifically,<br />
consideration has been given to The Town and Country Planning (<strong>Environmental</strong> Impact<br />
Assessment) (Amendment) (Wales) Regulations 2008 4 . Reference has also been made to<br />
currently available good practice guidance in EIA including:<br />
<strong>Environmental</strong> Impact Assessment: A Guide to Good Practice and Procedures. A Consultation<br />
Paper 2006 5 ;<br />
<strong>Environmental</strong> Impact Assessment - A Guide to Procedures, Department of the Environment,<br />
Transport and Regions (DETR) 2000 6 ;<br />
Circular 02/99 - <strong>Environmental</strong> Impact Assessment, DETR 7 ;<br />
Topic specific guidance referred to in each technical chapter of this ES where appropriate.<br />
2.3. The EIA has considered the likely significant environmental effects of the Development, utilising<br />
current knowledge of the Site and the surrounding environment. Based on the findings of the<br />
studies undertaken as part of the EIA, methods of avoiding, reducing, or offsetting significant<br />
adverse effects (collectively known as ‘mitigation measures’) have been identified. Such<br />
mitigation measures are set out in each relevant technical chapter of the ES.<br />
2.4. In line with best practice guidance, a Scoping Study was undertaken at the start of the<br />
assessment process to identify the environmental issues to be addressed in the ES. Further<br />
details of this study are provided later in this Chapter under the heading ‘Scoping the EIA’.<br />
2.5. Detailed technical studies have been ongoing throughout the design process, providing<br />
information about environmental issues and constraints which may affect the Development. The<br />
Applicant and the design team have therefore taken these environmental issues and constraints<br />
into account during the design evolution and sought to ‘design out’ potential adverse effects<br />
wherever possible. Further details are provided in Chapter 4: Alternatives and Design Evolution.<br />
2.6. The EIA has considered both beneficial and adverse effects of the Development both during the<br />
construction period and once the scheme is complete and occupied. In line with legislative and<br />
best practice requirements, direct, indirect, cumulative, short, medium, long-term, permanent,<br />
temporary, beneficial and adverse effects have been addressed where applicable. The approach<br />
taken in the assessment of cumulative effects is set out later in this chapter and within<br />
Chapter 17: Cumulative Effects.<br />

Location of Information in the ES<br />
2.7. The EIA Regulations state that an ES must include the information referred to in Part 1 of<br />
Schedule 4 as is:<br />
"(a) reasonably required to assess the environmental effects of the development and which the<br />
applicant can, having regard in particular to current knowledge and methods of assessment,<br />
reasonably be required to compile but (b) that includes at least the information referred to in<br />
Part II of Schedule 4".<br />
2.8. Table 2.1 lists the information referred to in Part 1 of Schedule 4 with relevant cross-reference<br />
indicating where such information is provided within this ES.<br />

2.9. 'Scoping' is an important component of the EIA process, and involves focusing the study (and<br />
hence the ES) on those issues of greatest potential significance. Scoping is also an important<br />
exercise to ensure that all likely significant effects of the construction and operational phases of<br />
the Development have been identified and are assessed through the EIA process, thereby<br />
ensuring appropriate mitigation options have been considered and incorporated into the scheme<br />
as necessary.<br />
2.10. An EIA Scoping Report was prepared and submitted to NCC on 19 September 2011 together with<br />
a formal request for a Scoping Opinion under the provisions of the EIA Regulations. The Scoping<br />
Report set out the proposed approach to the EIA and identified the likely significant effects that<br />
may arise from the Development. It also provided justification for ‘scoping-out’ issues that were<br />
not considered to be significant. The Scoping Report is included at Appendix 2.1 for reference.<br />
2.11. NCC provided a formal Scoping Opinion dated 14 October 2011 which is included at Appendix<br />
2.2. The Scoping Opinion provides the Council’s advice on the scope of the EIA and the<br />
methodology that would be used to assess the effects, with consideration to comments made<br />
from consultees. Consultation responses enclosed with the formal Scoping Opinion are also<br />
included in Appendix 2.2.<br />
Key Issues<br />
2.12. The key issues identified in NCC’s Scoping Opinion, alongside a summary of how these issues<br />
have been addressed in the EIA, is presented in Table 2.2.<br />

Table 2.2: Key Issues identified in NCC’s Scoping Opinion<br />
Issue<br />
Development Programme: The Environment Agency<br />
(EA) recommends that the ES should consider the<br />
types of waste that will arise during the demolition<br />
and construction phase of the development and<br />
potential impact this may have on the environment.<br />
The EA’s Planning Advice Note advises further on<br />
drainage and pollution prevention measures.<br />
Water Resources: Welsh Water advises that surface<br />
water drainage should not be connected to the public<br />
combined sewerage system due to insufficient<br />
capacity in the existing sewers.<br />
The use of SuDS for managing surface water runoff.<br />
Should be investigated.<br />
NCC advised that results from assessment of ground<br />
contamination and drainage should be fed into the<br />
ecological assessment.<br />
The EA advises that surface water run-off should be<br />
controlled as near to its source as possible through<br />
SuDS.<br />
The EA also advises that the EIA should incorporate<br />
information from within the Newport SEFRM<br />
modelling update of the Newport Tidal Model which is<br />
due in November 2011.<br />
Ground Conditions and Contamination: Countryside<br />
Council for Wales – avoid adverse impacts on<br />
features of the River Usk SAC and SSSI from<br />
contaminated discharge from construction and/or<br />
operation.<br />
Results from assessment of ground contamination<br />
and drainage should be fed into the ecological<br />
assessment.<br />
The EA recommends that the risk management<br />
framework provided in CLR11 should be followed.<br />
NCC requested that the ES should identify any<br />
potential pathways for run-off from the Development<br />
and, if necessary, proposed measures to minimise<br />
any identified impacts.<br />
Ecology: The application will require a Habitat<br />
Regulations Assessment.<br />

contamination sources, pathways and<br />
receptors and key potential pollutant linkages.<br />
The desk study was undertaken in accordance<br />
with current contaminated land assessment<br />
best practice, including the DEFRA<br />

Non-significant Issues<br />
2.14. Daylight, sunlight and overshadowing effects were included within the Scoping Report as a<br />
significant effect. However, as more detailed assessments of the Site were undertaken it was<br />
identified that the closest residential receptors were located at a distance where, given the scale<br />
of the proposals, there would be no impact on existing levels of lighting. As such no significant<br />
effects are anticipated from the Development in relation to daylight or sunlight and this issue has<br />
subsequently been scoped out of the EIA. An overshadowing assessment of the proposed public<br />
open spaces is included within the Design and Access <strong>Statement</strong>, to demonstrate suitability for<br />
use.<br />
2.15. It was agreed with NCC that a detailed assessment of waste was not required as part of the EIA<br />
because it is inevitable that waste would be generated during the demolition and construction<br />
phase; as a result of the demolition of the existing buildings and the construction of new buildings.<br />
This would be the case for any redevelopment project and the critical aspect is how this waste is<br />
managed. In line with mandatory legal requirements a Site Waste Management Plan (SWMP)<br />
would be prepared for the Development prior to demolition and construction works commencing.<br />
The implementation of a SWMP would help to ensure good site management practice would lead<br />
to a minimisation of waste creation and enable the reuse or recycling of waste materials that arise<br />
from the demolition and construction process, where practicable. The proposed methods to<br />
manage demolition and construction waste arising from the Site are summarised in Chapter 6:<br />
Development Programme, Demolition and Construction.<br />
2.16. Owing to the proposed increase in quantum of floorspace in comparison to the existing buildings,<br />
there would also likely to be an increase in the volume of waste generated from the Site.<br />
However, this increase is not considered significant in the context of NCC’s overall waste<br />
generation. Furthermore, the Development would incorporate appropriate waste storage and<br />
recycling facilities in accordance with the requirements set out by NCC and BREEAM. For these<br />
reasons, the likely effects associated with waste generation from the completed and operational<br />
Development are not considered to be significant and therefore waste has been scoped out of the<br />
ES.<br />

Consultation Process<br />
2.17. Statutory organisations were consulted throughout the design and EIA process via written<br />
consultations, telephone conversations, and meetings at key stages in the design. Each technical<br />
chapter sets out the consultation undertaken specific to the assessment.<br />
2.18. The following statutory and non-statutory organisations were consulted regarding the<br />
Development either directly by the project team or through NCC as part of their consultations:<br />
Newport City Council (NCC);<br />
Environment Agency Wales;<br />
Dŵr Cymru Welsh Water;<br />
Gwent Wildlife Trust;<br />
South East Wales Biodiversity Records Centre;<br />
Glamorgan Gwent Archaeological Trust Ltd;<br />
Countryside Council for Wales; and<br />
Local Residents.<br />
2.19. A public exhibition took place at Newport Library, John Frost Square on the 11 th and 12 th<br />
November 2011 which requested views on the Development from local residents, and local<br />
organisations. The majority of feedback received was positive towards the Development, notably<br />
with regards to the potential for socio-economic benefits from the scheme.<br />
2.20. Further information on public consultation is available in the Consultation <strong>Statement</strong> which<br />
accompanies the planning application. As stated above, consultation relevant to the EIA process<br />
is referred to in each technical chapter.<br />
Structure of the Technical Chapters<br />
2.21. Each environmental issue is assigned a separate chapter in the ES (Chapters 7 to 17), and within<br />
each of these chapters the assessment is presented and reported on in the following way:<br />
Introduction<br />
2.22. The Introduction section provides a brief summary of the issues considered, confirms the author<br />
and identified Appendices which accompany the chapter.<br />
Planning Policy Context<br />
2.23. The Planning Policy Context section of each chapter includes a brief summary of national,<br />
regional and local policies that are directly relevant to the particular environmental issue and<br />
assessment considered in that chapter. Relevant legislation and guidance is also identified where<br />
applicable.<br />
Assessment Methodology and Significance Criteria<br />
2.24. The Assessment Methodology and Significance Criteria section of each chapter sets out the<br />
methods used in undertaking the technical study of the particular environmental issue, together<br />
with an explanation of the approach to defining the significance of environmental effects with<br />
reference to published standard guidelines, best practice and defined significance criteria. The<br />
limitations applicable to the technical assessment are also defined in this section of each chapter,<br />
where relevant.<br />

2.25. This section of each chapter also describes the specific consultation undertaken as part of the<br />
assessment, for example to agree the scope and methodology.<br />
Baseline Conditions<br />
2.26. In order to assess the effects of the Development, it is necessary to determine the environmental<br />
conditions that currently exist on the Site, in the absence of redevelopment. These are known as<br />
‘baseline conditions’.<br />
Potential Effects<br />
2.27. This section of each chapter identifies the likely significant effects of the proposed Development<br />
during demolition and construction, and once the Development is complete and operational. This<br />
section includes an assessment of the significance of the effects in accordance with the<br />
significance criteria.<br />
Mitigation<br />
2.28. One of the main aims of EIA is to identify and so assist in developing mitigation measures to<br />
prevent, reduce and where possible, offset significant effects of a development. An iterative<br />
approach was adopted towards the design of the Development, which enabled a number of<br />
mitigation measures to be effectively designed into the Development, thereby reducing the need<br />
for further mitigation. Mitigation measures can relate to design, construction or the activities<br />
associated with the completed Development. Examples include:<br />
Design: Design solutions, such as the position or orientation of buildings<br />
within the Site. These have predominantly been incorporated into<br />
the Development as it has evolved and are therefore described in<br />
Chapter 4: Alternatives and Design Evolution and Chapter 5: The<br />
Proposed Development;<br />
Construction: Commitment to undertake the construction works in a specific<br />
way, for example the use of particular plant, phasing of the works,<br />
regular monitoring and implementation of an <strong>Environmental</strong><br />
Management Plan (EMP); and<br />
Completed Development: For example, inclusion of specific features to be incorporated at<br />
detailed design such as high specification glazing and acoustic<br />
trickle vents to mitigate effects of existing noise on future<br />
residents.<br />
2.29. Where significant environmental effects have been identified, the Applicant has committed to<br />
implement the appropriate mitigation measures as set out in the relevant technical chapter.<br />
Residual Effects<br />
2.30. This section identifies the remaining residual effects of the Development, assuming<br />
implementation of the proposed mitigation measures, and includes an assessment of the<br />
significance of those effects in accordance with the significance criteria.<br />
Summary and Conclusions<br />
2.31. This section of each chapter provides a tabulated summary of the findings of the assessment in<br />
relation to the relevant environmental issue.<br />

Evaluation of Significance<br />
2.32. The EIA Regulations stipulate that an ES should identify and describe the likely significant effects<br />
of the proposed Development on the environment. This requires consideration of:<br />
Positive and negative effects;<br />
Short, medium and long term effects;<br />
Direct and indirect effects;<br />
Permanent and temporary effects; and<br />
Cumulative effects and effect interactions.<br />
2.33. As described above, the ES identifies and assesses the likely significant effects of the proposals<br />
in relation to both demolition/construction activities and after completion of the proposed<br />
Development. <strong>Environmental</strong> effects have been predicted with reference to definitive standards<br />
and legislation where available. Where it has not been possible to quantify effects, qualitative<br />
assessments have been carried out, based on available knowledge and professional judgement.<br />
Where uncertainty exists, this has been noted in the relevant assessment chapter.<br />
2.34. The significance of predicted effects has been determined by reference to the effect criteria for<br />
each assessment topic. These criteria apply a common approach of classifying effects according<br />
to whether they are substantial, moderate or minor adverse, neutral or negligible, or substantial,<br />
moderate or minor beneficial.<br />
2.35. Specific criteria for each issue have been developed, giving due regard to the following:<br />
Extent, magnitude and complexity of the effect;<br />
Effect duration (whether short, medium or long term);<br />
Nature of the effect (whether direct or indirect, reversible or irreversible);<br />
Whether the effect occurs in isolation, is cumulative or interactive;<br />
Performance against environmental quality standards or other relevant pollution control<br />
thresholds;<br />
Sensitivity of the receptor; and<br />
Compatibility with environmental policies.<br />
2.36. For issues where definitive quality standards do not exist, significance has been based on the:<br />
Local, district, regional or national scale of value of the resource affected;<br />
Number of receptors affected;<br />
Sensitivity of those receptors; and<br />
Duration of the effect.<br />
2.37. In the context of the proposed Development, short to medium term effects are generally<br />
considered to be those associated with the demolition and construction phase, and long term<br />
effects are those associated with the completed and operational Development. Local effects are<br />
those affecting receptors on site or in neighbouring areas, while effects upon receptors in the<br />
wider area of Newport city are considered to be at a Borough level. Effects on the County of<br />
Gwent are considered to be at a Regional level. There are no national or international effects<br />
associated with the proposed Development.<br />

Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.02 EIA Methodology\E12300_Ch.2_ EIA Methodology_004_SB.docx
2.38. In order to provide a consistent approach to expressing the outcomes of the various studies<br />
undertaken as part of the EIA, the following terminology has been used throughout the majority of<br />
the ES. Effects have been expressed as:<br />
Adverse: Detrimental or negative effects to an environmental resource or<br />
receptor;<br />
Negligible: No significant effects to an environmental resource or receptor;<br />
and<br />
Beneficial: Advantageous or positive effects to an environmental resource or<br />
receptor.<br />
2.39. Where adverse or beneficial effects have been identified these have been assessed against the<br />
following scale:<br />
Minor significance: Slight, very short or highly localised effect of no significant<br />
consequence;<br />
Moderate significance: Limited effect (by extent, duration or magnitude) which may be<br />
considered significant; and<br />
Substantial significance: Considerable effect (by extent, duration or magnitude) of more<br />
than local significance or in breach of recognised acceptability,<br />
legislation, policy or standards.<br />
2.40. Each of the technical Chapters provides the criteria, including sources and justifications, for<br />
quantifying the different levels of effect. Where possible, this has been based upon quantitative<br />
and accepted criteria (for example, the National Air Quality Strategy air quality objectives),<br />
together with the use of value judgements and expert interpretations to establish to what extent an<br />
effect is environmentally significant.<br />
2.41. The only exception is the ecological impact assessment reported in Chapter 15:Ecology of the<br />
ES. This was undertaken in accordance with the IEEM 2006 guidelines 8 . In line with these<br />
guidelines, a significant effect has been defined as either positive or negative according to the<br />
following geographical scale:<br />
International;<br />
UK;<br />
National;<br />
Regional;<br />
County;<br />
District (or Unitary Authority, City or Borough);<br />
Local (or Parish); and<br />
Site (within the zone of influence only).<br />
Effect Interactions and Cumulative Effects<br />
2.42. The assessment of cumulative effects deals with two types of effect:<br />
Type 1 Effects: The combination of individual effects, for example noise and dust<br />
from one development on a particular receptor; and<br />
Type 2 Effects: Effects from several developments, which individually might be<br />
insignificant, but when considered together could result in a<br />
significant cumulative effect.<br />

Type 1 Effects (Effect Interactions)<br />
2.43. Type 1 effects would occur primarily during demolition and construction of the Development and a<br />
summary of the anticipated effect interactions is set out in Chapter 17: Cumulative Effects.<br />
2.44. Type 1 effects were assessed using the findings of all technical assessment included within this<br />
ES and professional judgement.<br />
Type 2 Effects (Cumulative Effects)<br />
2.45. Effects that result from incremental changes caused by other, reasonably foreseeable schemes in<br />
combination with the Development are known as ‘cumulative effects’. The EIA therefore takes<br />
account of the proposed Development together with other reasonably foreseeable developments<br />
in the area.<br />
2.46. A review of development schemes was undertaken to determine which developments could<br />
potentially give rise to significant cumulative effects in combination with the proposed<br />
Development. This considered schemes which have planning permission and also those which<br />
do not have planning permission but are regarded as being reasonably foreseeable. In<br />
determining the schemes to be considered in the cumulative assessment consideration was given<br />
to the following:<br />
Their distance from the Site;<br />
The proposed use and scale of the development; and<br />
The proposed floor area of the development or uplift in floor area.<br />
2.47. The Cumulative Developments include schemes within a 1km radius of the Site which involve an<br />
uplift of 10,000m 2 . Additionally, schemes with a lesser uplift within 200m were included where<br />
these could give rise to significant impacts or where these introduce new sensitive receptors.<br />
Owing to the nature of some of the assessments (including Transport Assessment and<br />
Townscape, Visual and Built Heritage Assessment), additional selected schemes further afield<br />
were also considered if they have the potential to give rise to significant cumulative impacts.<br />
2.48. Based on the criteria outlined above and following discussions with NCC, the following schemes<br />
were considered within the Type 2 cumulative assessment:<br />

available for each of the cumulative schemes. Where no cumulative effects are predicted, this is<br />
stated in the assessment.<br />
2.50. The ES sets out the cumulative effects of the proposed Development in Chapter 17: Cumulative<br />
Effects.<br />
Assumptions and Limitations<br />
2.51. The Regulations state that limitations and assumptions made during the course of the EIA are set<br />
out within the <strong>Environmental</strong> <strong>Statement</strong>. The principal assumptions that were made, and any<br />
limitations that were identified in undertaking the EIA are set out below:<br />
The assessments contained within each of the technical chapters are based upon the Detailed<br />
Plans, land use schedule and Design Principles submitted as part of the application;<br />
The assessment of demolition and construction effects are based upon the indicative<br />
demolition and construction timetable, phasing and methodologies as provided by the project<br />
team and agreed by the Applicant (refer to chapter 6: Development Programme, Demolition<br />
and Construction);<br />
Baseline conditions were established from a variety of sources, including site surveys and the<br />
review of historical data. However, due to the dynamic nature of certain aspects of the<br />
environment, conditions may change during the construction and operation of the<br />
Development;<br />
The design life of the Development is assumed to be 60 years;<br />
It has been assumed that information received from third parties is accurate, complete and up<br />
to date;<br />
Necessary off-site services infrastructure upgrades, where required to service the proposed<br />
Development, would be carried out by statutory undertakers or utility companies;<br />
All of the principal existing land uses adjoining the Site remain substantially unaltered, with the<br />
exception of the cumulative schemes listed in Chapter 17: Cumulative Effects;<br />
The design, construction and operation of the Development would satisfy environmental<br />
standards consistent with contemporary legislation, practice and knowledge as a minimum, but<br />
would also strive to achieve best practice at the time of the works where reasonable;<br />
An <strong>Environmental</strong> Management Plan (EMP) would be discussed and agreed with NCC after<br />
the planning application is determined, to control subsequent construction activities. This EMP<br />
would be enforced and monitored during all key stages of the demolition of the existing Site<br />
and the construction of the Development. A framework for the EMP is set out in Chapter 6:<br />
Development Programme, Demolition and Construction;<br />
The cumulative effects assessment is based on those schemes considered to be reasonably<br />
foreseeable and assumptions regarding their programme for implementation. The actual<br />

cumulative effects would be dependent on whether these schemes are implemented and their<br />
timing; and<br />
Assumptions and limitations specifically relevant to each topic are set out in each technical<br />
chapter.<br />
2.52. In addition to the above a specific limitation relates to the temporary relocation of the bus station.<br />
Whilst the demolition of the existing bus station, and the construction of the new one are both to<br />
be undertaken by the Applicant as part of the Proposals, it is the responsibility of NCC to provide<br />
alternative facilities during the construction works. Whilst the Applicant has accommodated the<br />
bus station on Site for as long as practicable, and will fast track the construction of the new facility<br />
in order to minimise disruption to bus users, there will be a period estimated to be just over a year,<br />
where an alternative facility will need to be provided. At the time of writing this ES no information<br />
had been provided by NCC with respect to the alternative facility, or facilities, that will be<br />
implemented during the time the bus station is not available on the Site. As a result it has not<br />
been possible to undertake a detailed assessment of the environmental effects of the alternative<br />
facilities. Further assessment of these issues should be undertaken by NCC when developing the<br />
proposals for the temporary bus station relocation.<br />

3. Site Description and Setting<br />
Introduction<br />
3.1. This Chapter has been written by Waterman Energy, Environment & Design Ltd (Waterman EED)<br />
and describes the location and setting of the Site as well as existing land use on and around the<br />
Site. The Chapter also provides a summary of the key environmental characteristics of the Site<br />
and its surroundings, thereby identifying potentially sensitive receptors which may be affected by<br />
the proposed Development.<br />
3.2. A full description of the baseline conditions relevant to each technical assessment of the EIA is<br />
provided in each technical chapter of this ES (Chapters 7 to 17). Details of the proposed<br />
demolition and construction sequence and programme of works are outlined separately in<br />
Chapter 6: Development Programme, Demolition and Construction.<br />
Location and Setting<br />
3.3. As described in Chapter 1: Introduction and illustrated in Figure 1.1, the Site is located within<br />
Newport City centre within the administrative boundary of Newport City Council.<br />
3.4. Figures 1.2, the Site Location Plan, illustrate the planning application boundary and show that the<br />
Development Site is located between Kingsway / Usk Way to the east, the Kingsway Shopping<br />
Centre to the south, Corn Street to the north and commercial and public buildings off Commercial<br />
Street to the west.<br />
Topography<br />
3.5. Topography of the Site generally slopes up from east to west. The existing bus station area is<br />
located at a lower level, with John Frost Square forming a flat ‘terrace’ within the Site, below<br />
Commercial Street further to the west. Upper Dock Street slopes up from Corn Street towards<br />
John Frost Square. Existing local ground levels range from approximately 9.0m AOD in the<br />
riverside area to the east of the Site, to 14.3m AOD at Commercial Street to the west, although<br />
there are pockets of land within the Site at levels below 9.0m AOD.<br />
Predominant Land Uses<br />
On Site<br />
3.6. The Site comprises various retail, food and service sector units, along Upper Dock Street and<br />
around John Frost Square. The current Iceland building is known as the Winllan Building. The<br />
southern part of the Site comprises a disused multi-storey car park with street level retail units and<br />
three Electricity Sub Stations. Servicing is provided at a level below John Frost Square, which is<br />
accessed through the adjacent Kingsway Shopping Centre.<br />
3.7. The eastern portion of the site is currently occupied by Newport bus station, which also includes<br />
Newport’s main taxi rank. In addition to bus stands some welfare and ticketing facilities are also<br />
provided in the bus station.<br />
Surrounding Land Uses<br />
3.8. The area surrounding the Site comprises a mix of uses including:<br />
Friars Walk, Newport<br />
Chapter 3: Site Description and Setting Page - 1
The recently redeveloped Kingsway Shopping Centre, including the Newport Library, Art<br />
Gallery and Museum is located directly adjacent to the southern boundary of the Site;<br />
Newport Leisure Centre which lies 20m to the south-east;<br />
Retail units to the west and north of the Site, facing onto Commercial Street and Corn Street;<br />
Chartist Tower a large office block is located approximately 100m to the west of the Site;<br />
The A4042 Kingsway West / Usk Way which runs adjacent to the eastern Site boundary;<br />
The Potters Public House is located to the north of the Site;<br />
The tidal River Usk is located approximately 50m to the east of the Site boundary at its nearest<br />
point; and<br />
Areas of car parking, the University of Wales Newport and the Riverside Arts Centre are<br />
located between the river and the Kingsway, approximately 30m to the east of the Site.<br />
3.9. No residential properties have been identified on or directly adjacent to the Site, however a<br />
number of residential properties are located in terraces along Emlyn Street, Cross Street and<br />
Caroline Street, some 150m to the south-east of the Site.<br />
Transportation and Access<br />
3.10. The Site benefits from good accessibility to public transport. Newport Railway Station is<br />
approximately 400m from the site, which has regular services running to Swansea, Cardiff,<br />
Manchester and London Paddington. The current bus station, which is located adjacent to the<br />
Site, has regular services, providing connections to local amenities and services in Newport and<br />
Cardiff.<br />
3.11. The Site is located within Newport city centre, adjacent to Commercial Street the main pedestrian<br />
thoroughfare and retail core of the city. A cycle and pedestrian route is located along the River<br />
Usk, along with a connection to the east bank of the River Usk, via the Newport City Footbridge.<br />
There are currently pedestrian links from the city centre to the Usk across the Site, although these<br />
feature steps and grade changes that make them unsuitable for disabled users.<br />
3.12. Transportation and access issues are discussed further within Chapter 8: Transport and Access.<br />
Noise, Vibration and Air Quality<br />
3.13. A desk-based study and site walkover was carried out in October 2011 to identify existing and<br />
future noise sensitive receptors (NSRs) that could potentially be affected by noise arising from the<br />
construction works and operation of the proposed Development. Noise monitoring was<br />
undertaken at locations representative of the closest Noise Sensitive Receptors (NSRs) to the site<br />
boundary in October 2011 found that noise levels during the daytime ranged between 55 and<br />
72dB LAeq,T. Dominant noise sources in the Development area were noted to be from road traffic<br />
however, however limited vehicle noise associated with HGVs accessing the existing commercial<br />
premises was also noted. During the night-time period noise levels were typically lower (48dB<br />
LAeq,8hr to 59dB LAeq,8hr) than those experienced during the daytime period as a result of reduced<br />
road and rail traffic noise during this period. Noise and vibration issues are discussed further<br />
within Chapter 10: Noise and Vibration.<br />
3.14. The Site is not located within an Air Quality Management Area (AQMA) however; construction and<br />
demolition works and a temporary increase in heavy good vehicles (HGV) movements on the<br />
local road network could potentially impact on local air quality and subsequently local residents<br />
and occupants of surrounding buildings. Mitigation measures against these potential impacts<br />
have therefore been discussed and outlined in Chapter 9: Air Quality<br />
Friars Walk, Newport<br />
Chapter 3: Site Description and Setting Page - 2
Ground Conditions and Contamination<br />
3.15. Published geological information and previous investigations undertaken in close proximity<br />
indicate that the Site is likely to be underlain by Hard Standing overlying a Sub-base material and<br />
Made Ground followed by weathered bedrock / Alluvium overlying Marl and beyond this,<br />
Mudstone/Silstone overlying Sandstone.<br />
3.16. The Environment Agency indicate that the Sandstone underlying the site is classified as a minor<br />
aquifer of variable permeability. The minor aquifer status indicates the aquifer may contain<br />
significant amounts of water that are important for local supplies and for base flows to local rivers.<br />
Archaeology and Built Heritage<br />
3.17. The western ends of Friar’s Walk, Austin Friar’s and Llanarth Street are located within the Town<br />
Centre Conservation Area. The location of all conservation areas within the vicinity, namely the<br />
Town Centre Conservation Area, Lower Dock Street Conservation Area and St Woolos<br />
Conservation Area further south is shown within Figure 13.1.<br />
3.18. The archaeological potential of the Site has been reviewed. The development of the Site since<br />
the 19 th century suggests that archaeological remains will have been significantly disturbed, and<br />
would be expected to be truncated and highly fragmented, with only limited areas of survival.<br />
Water Resources and Flood Risk<br />
3.19. The Site is located in a Flood Zone B. Zone B is described as an area known to have been<br />
flooded in the past evidenced by sedimentary deposits.<br />
3.20. The nearest surface water to the Site is the Town Pill which is located 10m to the north of the site.<br />
This is a culverted water feature which flows eastwards into the River Usk, which is located 50m<br />
northeast of the site flowing southeast.<br />
3.21. The existing surface water systems serving the Site area comprise a variety of separate and<br />
combined gravity systems which historically discharged directly to the River via tidal flaps but now<br />
outfall into the combined sewer located under Kingsway West / Usk Way.<br />
3.22. The combined sewer is of large capacity and flows in a southerly direction to a pumping station<br />
which transfers the combined flows to Nash Waste Water Treatment Works<br />
Townscape and Visual<br />
3.23. The extant townscape of the Site comprises Newport Bus Station and associated bus bay area,<br />
adjoining multi-storey car park, retail units, John Frost Square and pedestrian routes. Built form<br />
dates from the 1960s and displays many characteristics of modernist architecture synonymous<br />
with the period including clean architectural forms and lines, covered walkways, minimal façade<br />
detailing and a preponderance of concrete and brick. As such, the Site appears somewhat dated,<br />
although does not exhibit the dilapidation and neglect often associated with other city and town<br />
centres of a similar period.<br />
3.24. Amongst the recent mid-20th century built form of the City centre are a number of Victorian and<br />
Edwardian buildings, notably the Newport Market and the elegant suburbs of St Woolos, visible<br />
manifestations of the wealth generated by the industrial heritage of the City. To the east of the<br />
Site, the regeneration of the riverside has progressed apace with an assortment of futuristic<br />
buildings jostling for attention on the water front.<br />
3.25. Townscape and Visual Issues are discussed further within Chapter 13: Townscape and Visual.<br />
Friars Walk, Newport<br />
Chapter 3: Site Description and Setting Page - 3
Ecology<br />
3.26. The Site itself is not within any statutory or non-statutory designated nature conservation sites.<br />
The nearest statutory designated site is the River Usk, a Special Area of Conservation (SAC) and<br />
Site of Special Scientific Interest (SSSI), located east of the Site. A number of trees are located<br />
within the Site, or adjacent to it, which have been recorded in the Arboriculture Survey, included<br />
as Appendix 3.1.<br />
Sensitive Receptors<br />
3.27. A review of the existing Site and its surrounds has identified a range of receptors and / or<br />
environmental constraints which could potentially be sensitive to environmental effects resulting<br />
from the Development. These are listed below in Table 3.1.<br />

4. Alternatives and Design Evolution<br />
Introduction<br />
4.1. This Chapter, prepared by Waterman Energy, Environment & Design Ltd (Waterman EED) in<br />
conjunction with Leslie Jones Architects, describes the considerations, opportunities and<br />
constraints that have influenced the layout, massing and design of the Development.<br />
4.2. The Chapter also describes the main alternatives to the Development which have been<br />
considered by the Applicant and Design Team and the key reasons for these alterations having<br />
been made.<br />
Site Considerations and Constraints<br />
4.3. The range of considerations and constraints which affected the design and layout of the proposed<br />
Development are summarised in Table 4.1 below, including a description of the influence they had<br />
where appropriate.<br />
Table 4.1: Site considerations and constraints<br />
Issue Specific Opportunities and Constraints<br />
Planning Policy The relevant planning policy guidance for the development is included in the<br />
Planning Policy Wales Technical Advice Notes (TAN), Newport City Council,<br />
Unitary Development Plan 1996-2011 1 , and the Newport City Centre Draft<br />
Supplementary Planning Guidance (SPG). The SPG identifies the ‘City Centre<br />
– Commercial Core’ and within it John Frost Square, as a Priority Action Area<br />
and offers clear and concise guidance on the type and scale of development<br />
that will be encouraged in this area. This guidance is particularly relevant to<br />
the current application site<br />
The realisation of the relevant planning policy for the Site is envisaged through<br />
the delivery of a mixed use scheme designed to respect existing townscape.<br />
In addition, it is to: enhance accessibility and safety of the city centre; reunite<br />
the River Usk and the city centre; provide parking; and provide a good quality<br />
of public transport infrastructure within a more sustainable city centre<br />
environment. The precedent for the Site development was established in<br />
March 2006, when planning permission was granted for a retail led mixed use<br />
scheme, to the previous developers Modus Corovest. .<br />
Land uses and built<br />
environment<br />
The scheme is designed to integrate into the existing retail circuit of Newport<br />
City Centre and also to provide new east/west routes through the Site<br />
connecting the city centre with the riverfront.<br />
The approach to architecture and materials reflects two distinct themes and<br />
complimentary approaches. The riverside corridor reflects modern Newport<br />
with the contemporary buildings and structures of the University, Riverfront<br />
Theatre and Arts Centre and the new Newport city Bridge. The city side of the<br />
scheme faces the adjoining conservation area and Newport’s historic core with<br />
more traditional masonry detailed buildings and a more traditional scale. The<br />
elevations of the structures therefore vary according to the nature of the<br />
building, its use and its location. The palette of materials draws from the<br />
colours and materials found in the Welsh countryside as well as the existing<br />
built form within Newport.<br />
Site Levels As described within Chapter 3: Site Description and Setting, the Site generally<br />
slopes up from east to west. Existing local ground levels range from<br />
approximately 9.0m AOD in the riverside area to the east of the Site, to 14.3m<br />
AOD at Commercial Street in the west, although there are pockets of land<br />
within the Site at levels below 9.0m AOD.<br />
Site levels have been carefully considered in order to ensure ease of<br />
circulation, movement and accessibility for all.<br />

Issue Specific Opportunities and Constraints<br />
Socio-economics Newport’s shopping and leisure offer has suffered considerably with the failure<br />
of an earlier proposals for retail and mixed development of the Site, together<br />
with the newer out of town shopping retail park in nearby Spytty. Some major<br />
retailers have either abandoned Newport city centre in favour of more modern<br />
facilities or are considering making the move out of town.<br />
The buildings on-site are typically in poor condition, and a number of the retail<br />
units are vacant. The application proposal would provide a significant boost to<br />
the local economy.<br />

Heritage<br />
The city is well connected to the nearby metropolitan area and the central bus<br />
station currently located within the eastern part of the Site. The station<br />
accommodates city buses, long haulage coaches and a large number of<br />
registered taxis.<br />
The current bus station on the Site features redundant bays and is outdated<br />
with poor facilities. One of the main taxi ranks in the city is also located at the<br />
bus station. The current layout of the bus station creates conflict between<br />
buses and taxis.<br />
The bus station will need to be kept open during redevelopment works to<br />
ensure minimum disruption to the local bus network. As such it is proposed to<br />
temporarily move the bus station offsite, to temporary facilities provided by<br />
NCC. Details of these are not currently known.<br />
The Site currently suffers from poor permeability and accessibility, particularly<br />
for cyclists and the disabled. Furthermore the use of space e.g. John Frost<br />
Square and disused car parks is inefficient.<br />
Key pedestrian links would be created or improved by the Development.<br />
These include both east/west linkages between the city and the river and<br />
north/south linkages. Access to the Development’s two primary levels of the<br />
riverside and Commercial Street would be provided by lifts and a staircase at<br />
the southern end of the scheme within Usk Plaza and by lifts and stairs at the<br />
northern end of Friars Walk. In addition, pedestrians leaving the bus station to<br />
Corn Street would also be able to access Commercial Street following the<br />
natural gradient of the street.<br />
Cycle facilities on the Site are currently poor, with an absence of secure cycle<br />
storage. The proposals will be required to address this current shortcoming.<br />
The presence of potential contamination from previous Site uses has required<br />
consideration with respect to appropriate intrusive construction methodologies<br />
to avoid further contamination risks and the potential need for remediation.<br />
Further details are provided in Chapter 11: Ground Conditions and<br />
Contamination.<br />
The majority of the Site is located in a Flood Zone B. The guidance requires<br />
that for sites located in Zone B the flood level of an extreme i.e. 0.1% (1 in<br />
1,000 year) flood event be calculated and compared to the proposed site<br />
levels.<br />
An FCA has been completed for the Development and the use of Sustainable<br />
Urban Drainage Systems (SuDS) carefully considered. Further details are<br />
provided within Chapter 12: Water Resources and Flood Risk.<br />
The development of the Site since the 19th century suggests that<br />
archaeological remains will have been significantly disturbed, and would be<br />
expected to be truncated and highly fragmentary, with only limited areas of<br />
survival. As such the Site is deemed to have minimal archaeological potential.<br />
Archaeological works would be carried out in line with the written scheme of<br />
investigation (WSI) already approved by NCC.<br />
The proposed Development includes the partial demolition of a building within<br />
the city centre Conservation Area. Therefore, it would directly impact on this<br />
designation, as well as alter the relationship of the Site to the setting of the<br />
Conservation Area. The Potters Public House is to be incorporated into the<br />
proposed Development. Whilst this building is not listed the setting of this<br />

building and others of local interest could be impacted by the Proposals.<br />
Townscape and Visual The potential impacts of the Development on townscape and visual amenity<br />
could include the temporary visual intrusion during the construction works,<br />
impacts upon local views, and changes to the character, context and quality of<br />
the local townscape as a result of the proportion, scale, enclosure, street<br />
pattern and views of the proposed Development.<br />
Ecology The Site has been subject to ecological surveys in 2011, which concluded that<br />
the Site is of low ecological value and does not yield any direct evidence of<br />
protected species including bats. Furthermore, the Site does not include any<br />
statutory or non-statutory sites designated for nature conservation value.<br />
The River Usk, located 50m north-east of the Site, is designated as a Site of<br />
Special Scientific Interest (SSSI) and a Special Area of Conservation (SAC).<br />
Despite the above, the Applicant is committed to the principles of sustainable<br />
development. Accordingly, the Development incorporates ecological<br />
enhancements. Further details are provided within Chapter 15: Ecology.<br />
Wind The suitability of the local wind environment has been considered in terms of<br />
the comfort levels required for particular pedestrian activities on and around<br />
the Site. This is of particular relevance to the provision of public realm space<br />
and pedestrian routes within the Development. Further details are provided<br />
within Chapter 16: Wind.<br />
Alternatives<br />
4.4. Under The Town and Country Planning (<strong>Environmental</strong> Impact Assessment) Regulations 1999<br />
(as amended) 2 , an ES is required to provide<br />
"an outline of the main alternatives studied by the applicant ... and an indication of the main<br />
reasons for his choice, taking into account the environmental effects".<br />
4.5. The following sections therefore review, in general terms, the main alternatives to the<br />
Development which have been considered by the Applicant.<br />
4.6. The design of the proposed Development commenced with a detailed review of the aims and<br />
objectives laid out within the Central Area Masterplan for Newport, set out in Newport 2020:<br />
Unlimited Vision 3 document, guidance included within the Newport City Centre Draft<br />
Supplementary Planning Guidance 4 together with the constraints which have been summarised<br />
within this chapter in Table 4.1. As the EIA progressed in parallel with the design process,<br />
iterations to design elements have been made to minimise the potential adverse environmental<br />
effects which have been identified from baseline surveys and analyses.<br />
4.7. The main alternatives to the Development that were considered by the Applicant included:<br />
The ‘Do Nothing' alternative (i.e. where no development takes place); and<br />
Alternative Designs.<br />
4.8. The Development has been designed to respond to the planning policy objectives for the mixed<br />
use re-development of the Site. As such, no alternative sites have been considered by the<br />
Applicant. Detailed information on the planning policy context of the Development is provided in<br />
the Planning <strong>Statement</strong> submitted in support of the planning application.<br />

The ‘Do-Nothing’ Alternative<br />
4.9. Guidance on the preparation of an EIA suggests that it is good practice to consider the evolution<br />
of a site in the absence of specific proposals within an ES, i.e. the ‘Do Nothing’ alternative. The<br />
‘Do Nothing’ alternative refers to the option of leaving the Site in its current state, which would<br />
result in a number of negative impacts, as follows:<br />
The Development is intended to act as a catalyst for wider regeneration of the city centre. If it<br />
does not proceed, the opportunity to regenerate an identified development site within the city<br />
centre will be lost, and aspirations of NCC and Newport Unlimited will not be met;<br />
There would be a continuing decline in the built environment within the Site, notably of the bus<br />
station and disused car parks. This together with the continued presence of visually<br />
unappealing buildings would leave users of the Site and visitors to the local area with a<br />
negative impression of the City;<br />
Poor safety / security;<br />
Levels of activity within the Site, particularly at night, would remain at a low level given the<br />
nature of the current pedestrian links through the Site and mix of land uses;<br />
Use of space e.g. John Frost Square and the disused car parks would remain inefficient;<br />
The diversity of the land uses within the Site would remain low;<br />
The potential for improvements to the setting of the local conservation areas would be lost;<br />
and<br />
The positive socio-economic benefits that the Development would bring in terms of increased<br />
trade and employment in the city would not occur.<br />
4.10. It is considered that the benefits of redeveloping the Site significantly outweigh any adverse<br />
impacts that could occur. As demonstrated throughout the ES, the development of the Site will<br />
accord with both national and local planning policy objectives.<br />
Alternative Designs<br />
4.11. The initial brief arises directly from the Central Area Plan for Newport and the Newport Unlimited<br />
Vision 2020 document which identified a number objectives and targets for the successful<br />
redevelopment of the Site. The key principals were to:<br />
Revitalise the city centre and add additional retail opportunities to compliment Commercial<br />
Street;<br />
Improve pedestrian links between the city and the river;<br />
Introduce a greater diversity into the city with leisure and restaurant uses;<br />
Provide better public transport facilities;<br />
Contribute to improved accessibility to the city centre; and<br />
Create a network of linked and improved public spaces.<br />
4.12. Specific commercial brief requirements were to:<br />
Incorporate a department store of approximately 75,000sq ft / 6,967m 2 ;<br />
Incorporate a multi screen cinema with 6 / 7 screens;<br />
Incorporate a new restaurant quarter to encourage an evening economy; and<br />
Incorporate additional shoppers car parking to supplement the Kingsway car park.<br />

Chapter 4 Alternatives Newport_JB_061211_001
4.13. Following a competition, Modus Corovest Limited were appointed as NCC’s preferred developer.<br />
Following this, in 2005, proposals based on the competition design were submitted by Modus<br />
Corovest Limited, which were subsequently amended prior to planning consent being granted<br />
subject to conditions in March 2008 (Application Ref 08/0201). This permission is due to expire in<br />
March 2013. These proposals were within almost the exact same site boundary as the current<br />
Proposals, however, the density of the proposals were considerably higher. Whilst the proposals<br />
were retail led, it also included a hotel and a significant quantum of residential accommodation,<br />
which included a residential tower.<br />
4.14. In addition the scheme offered approximately 1,400 car parking spaces within a multi-storey car<br />
park within the Site and 320 additional spaces provided by the development through a car park<br />
above the department store. Approximately 160 additional spaces would have been created<br />
through the construction of a basement car park beneath the hotel/retail block fronting onto<br />
Kingsway.<br />
4.15. Following the withdrawal of Modus Corovest from the above scheme in 2008, due to economic<br />
trading conditions, NCC obtained development proposals from other potential development<br />
partners. The original scheme was deemed too large and complex for the changed economic<br />
conditions, and this was reflected by the various proposals submitted to NCC. A new lower<br />
density development acknowledging the changed economic circumstances whilst retaining the<br />
same regeneration objectives was therefore proposed. Following a review of these proposals<br />
NCC considered that the new scheme should provide:<br />
Good retail space focussed on one primary level;<br />
Maximum flexibility of space;<br />
Limited other uses including complimentary leisure but no residential;<br />
Good parking and access; and<br />
Simple design to achieve viable construction cost.<br />
4.16. It was also identified that the key objective should remain in that the scheme must be of sufficient<br />
quality and critical mass to achieve a step change in perception of the city’s:<br />
Architecture and urban design;<br />
Public realm; and<br />
Retail offer.<br />
4.17. For the design competition Leslie Jones Architects, on behalf of the Applicant looked at two main<br />
alternative layouts for the Site. These comprised a scheme largely similar to the proposed<br />
Development, but without the bus station, and a ‘big box’ option, more akin to a retail park. The<br />
big box option provided poor permeability and linkage with the existing City centre, and would<br />
have had a negative impact on the townscape along Usk Way and across the Newport City Bridge<br />
to East Newport. Consequently this design alternative was not considered further, as it would not<br />
meet the requirements of the NCC Brief.<br />
4.18. Following the Applicant becoming NCC’s development partner, the submitted design proposals<br />
were reviewed as part of the process to take them forward to planning submission. Rather than<br />
alternative layouts being considered, it was considered that a number of design studies would be<br />
undertaken to refine the design proposals. Where the results were considered positive these<br />
changes to the design were incorporated. The following paragraphs set out the principal<br />
alternatives to the layout that were considered.<br />
Friars Walk, Newport<br />
Chapter 4: Alternatives Page 5 of 6<br />
Chapter 4 Alternatives Newport_JB_061211_001
Realignment of the main retail street to follow the axis of Kingsway and the River Usk rather than<br />
Commercial Street.<br />
4.19. This alternative would permit the development of a new public space, linking Commercial Street to<br />
the River Usk, and incorporating the cinema and leisure units. Given the potential benefits with<br />
respect to permeability of the Site, this change was taken forward.<br />
Inclusion of the Bus Station<br />
4.20. Following a review of the city centre bus strategy, NCC was decided that it would after all be<br />
necessary to incorporate a new bus station into the proposals. As the earlier designs would no<br />
longer meet the brief, it was determined that the retail street should be shortened and the<br />
department store reconfigured to accommodate a condensed and more efficient bus station in the<br />
north eastern corner of the Site. In order to meet the revised brief the earlier design options had<br />
to be discounted.<br />
Conclusions<br />
4.21. It is considered that the proposed Development has responded positively to the site consideration<br />
and constraints, in particular the challenges of the changing site levels. Through continuous<br />
dialogue and discussion with NCC together with public consultation and technical studies, the<br />
proposed Development has sought to respond to the brief to provide the desired step change in<br />
the city’s architecture and urban design, retail offer and public realm.<br />

5. The Development<br />
Introduction<br />
5.1. This Chapter provides a description of the proposed Development, which forms the basis of the<br />
<strong>Environmental</strong> Impact Assessment (EIA). As noted in Chapter 1: Introduction, a full planning<br />
application is being submitted. This Chapter has been informed by the Development Planning<br />
Application. Details of the anticipated construction activities and programme of works, are<br />
outlined separately in Chapter 6: Development Programme, Demolition and Construction.<br />
5.2. This Chapter was written by Waterman Energy, Environment & Design (Waterman EED) with<br />
input from Leslie Jones.<br />
Overview of the Development<br />
5.3. The proposals involve the demolition of existing on-site buildings and structures and the<br />
construction of new retail and leisure uses, a reconfigured bus station, and an extension to the<br />
existing Potters Public House. A new public square would be created, to be known as Usk Plaza,<br />
and John Frost Square would be reconfigured. The proposed Development would seek to<br />
integrate with the recent Usk Way boulevard project, and form a new high quality, accessible link<br />
from Commercial Street to the River Usk and the Newport City Footbridge.<br />
5.4. The planning application forms describe the proposed Development as follows:<br />
“Demolition and mixed use development including retail (A1), leisure / cinema (D2), cafes /<br />
restaurants (A3), extension to existing public house (A4), associated car parking, new bus station,<br />
landscaping and access”<br />
5.5. The planning application drawings define the layout of the buildings, the location of land uses, the<br />
height, width and length of each building, key access locations, the main vehicular and pedestrian<br />
routes, and open spaces within the Development.<br />
5.6. A conservation area application is also being submitted owing to the Site’s location within the<br />
Town Centre Conservation Area (TCCA). The western extent of the TCCA boundary is set out on<br />

Built Development<br />
Retail Layout<br />
5.9. The proposed Development is designed to integrate into the existing retail circuit of Newport and<br />
also to provide new east/west routes through the Site connecting the city centre with the riverfront.<br />
5.10. The new retail units would be set out primarily along a new double height covered arcade (Friars<br />
Walk) linking John Frost Square and Usk Plaza to the new department store and Austin Friars.<br />
The southern end of the new retail street would comprise the leisure quarter consisting of new<br />
public realm (Usk Plaza), restaurants and a cinema. This central location at the confluence of<br />
both north/south and east/west routes would strengthen the existing Kingsway Centre and create<br />
a new retail circuit in the city consisting of Kingsway, Commercial Street and Friars Walk.<br />
5.11. The Development would also make use of the significant level change across the Site by locating<br />
the retail at the upper level on a flat plate, level with Commercial Street, creating ease of access<br />
throughout and located over the lower level of parking and concealed servicing. At grade access<br />
would be available from the parking into the restaurant quarter within Usk Plaza.
Building Heights<br />
5.12. In order to integrate the Development with the surrounding built form, the buildings would<br />
generally be three storeys on the riverside reflecting the greater urban scale of the vehicular<br />
corridor and two storeys on the city side reflecting the pedestrian approaches and smaller scale of<br />
the Victorian city. Whilst the buildings along Commercial Street are generally to three stories, the<br />
greater ceiling to floor heights of modern retail premises allows for only two storeys within the<br />
same building height. The retail units rise to 23.175m AOD to the top of parapet, whilst the<br />
department store rises to 25.1m AOD at the top of the parapet. The roof over Friars Walk will rise<br />
to some 28m AOD at its highest point. The department store will trade at three levels, with a<br />
reduced trading floor present at the Kingsway level, with an at grade entrance into the car park.<br />
Active Frontages<br />
5.13. The delivery and maximisation of active frontages is a key objective of the development and of the<br />
Newport Unlimited City Masterplan. The commercial leasability of the varying locations is relevant<br />
in defining the active frontages and the only practical limitations on achieving full outward looking<br />
activity are with the car park and the department store, the latter requiring generally an inward<br />
looking box. In each of these cases artwork, and display windows together with temporary<br />
activities and public realm opportunities will be considered at the detailed design stage, however<br />
careful design of the layout has delivered a high percentage of active façade.<br />
Approach to Elevations and Materials<br />
5.14. The approach to architecture and materials reflects two distinct themes and complimentary<br />
approaches. The riverside corridor reflects modern, forward looking and aspirational Newport<br />
with the contemporary buildings and structures of the University, Riverfront Theatre and Arts<br />
Centre and the new Usk Bridge. Those elevations facing John Frost Square and Upper Dock<br />
Street shall be more traditional, typically including local stone and brick, in combination with more<br />
modern cladding materials, to respect the scale and nature of Llanarth Street, Upper Dock Street<br />
and Austin Friars. The treatment of the elevations therefore varies according to the nature of the<br />
building, its use and its location. The palette of materials draws from the colours and materials<br />
found in the Welsh countryside as well as the existing built form within Newport.<br />
Department Store<br />
5.15. The department store would lie at the northern end of the scheme and would have a significant<br />
presence onto Kingsway West and Upper Dock Street. The base of the store would be<br />
constructed using a slate coloured brick, above which a flat metal cladding would be used in a<br />
varied range of colours.<br />
Kingsway West<br />
5.16. Larger units have been included at either end, suitable for major stores, and accordingly these<br />
units shall have a greater visual presence. Between these units the elevation would be<br />
modulated to break down the scale and length of the elevation into a new terrace of buildings.<br />
The elevation would use a variety of pastel colours as well as articulating the planes of these<br />
materials in a modern rainscreen cladding. At street level a colonnade would provide a sheltered<br />
walkway between Usk Plaza and the bus station. The car park would be visible through an<br />
anodised metal screen, to facilitate ventilation, and interspersed with artwork panels to provide<br />
visual interest.<br />
Friars Walk, Newport,<br />
Chapter 5: The Development - Page 3
Usk Plaza<br />
5.17. As the elevation moves into Usk Plaza, the materials used would change. Usk Plaza would form<br />
the social and leisure hub of the development with a variety of restaurants and cafés as well as<br />
the cinema anchoring the southern end of the scheme. The materials used would be banded<br />
earth colours with bright colour highlights to the cinema.<br />
Friars Walk<br />
5.18. The intent of the design of the elevations to Friars Walk is to provide a framework for the tenants’<br />
shop fronts. The design would allow for double height shop fronts to be inserted between the tile<br />
clad piers forming the edges of the units. Above the shop fronts, render or polyester powder coat<br />
panels would be provided. In order to differentiate the department store, the façade within Friars<br />
Walk would use a similar range of materials to the facades employed on Upper Dock Street. A<br />
Tenant’s shop front guide would be produced to put forward a structure for the tenant’s to develop<br />
their designs for their shop fronts in a controlled manner with defined signage locations and a<br />
minimum quality threshold.<br />
John Frost Square and Upper Dock Street<br />
5.19. The materials and elevational treatment to the new John Frost Square and Upper Dock Street<br />
would be more traditional. The elevations would be predominantly masonry construction with two<br />
types of brick, with zinc/metal cladding and stone to match the local stone colour. Single height<br />
shopfronts are preferred being more in scale with the adjoining street frontages and suitable for<br />
more independent retailers. They would respect the existing architecture, scale and materials<br />
found in both Upper Dock Street, Llanarth Street and Austin Friars.<br />
Winllan Building, Upper Dock Street<br />
5.20. The demolition of the rear section of the Winllan Building (Iceland) to reform Upper Dock Street<br />
and facilitate the delivery of Friars Walk would require new elevations to reclad the remaining<br />
section of the existing building. The elevations would be of high quality masonry construction to<br />
the existing concrete framed building with the opportunity to extend new active frontages down<br />
Austin Friars and round onto Upper Dock Street.<br />
Servicing<br />
5.21. Shared loading bays would give access to service corridors and lift cores to allow delivery to all<br />
units and restaurants. The department store would have its own dedicated service area.<br />
Provision would be made within the service area for refuse compaction and management. The<br />
service areas would be monitored by CCTV on a 24 hour basis.<br />
Car Parking<br />
5.22. In addition to the adjoining Kingsway multi storey car park providing 1,050 spaces a new single<br />
deck car park is proposed to provide a further 360 spaces. The car park would be well lit and<br />
secure and would have an above normal internal storey height of 3.5m which would allow it to be<br />
sufficiently light and airy. Access would be at grade for vehicles from Kingsway West and<br />
pedestrian access from the car park to the shops would also be at grade into Usk Plaza and at<br />
grade into a new atrium entrance at the northern end to a lift and stair core shared with the bus<br />
station. It would be provided with good levels of illumination as well as CCTV. Being on a single<br />
floorplate there would be good visibility throughout and a suitable level of activity. Disabled and<br />
parent and child spaces would be provided.<br />
Friars Walk, Newport,<br />
Chapter 5: The Development - Page 4
5.23. In addition provision for ‘Customer Collect’ would be provided to the department store within the<br />
car park, reflecting modern retailing changes towards ‘click and collect’ multichannel retailing and<br />
offering a point of difference for the future.<br />
Vertical Circulation<br />
5.24. Vertical circulation between the two primary levels of the riverside and Commercial Street would<br />
be provided by two lifts, and a grand shallow staircase at the southern end of the scheme within<br />
Usk Plaza. An enclosed lift core with three lifts and a feature stair at the northern end of Friars<br />
Walk. In addition people exiting the bus station to Corn Street would also be able to access<br />
Commercial Street following the natural gradient of the street.<br />
Public Transport<br />
Buses<br />
5.25. The Development would be well served by public transport through the provision of a reconfigured<br />
bus station to serve the city as part of the redevelopment. The present bus station sits within the<br />
boundary of the site but is outdated with poor facilities. The new bus station would be managed<br />
as part of the overall scheme management on behalf of Newport City Council. The new bus<br />
station would provide 15 stands which would be efficiently managed to accommodate all current<br />
local routes. In addition, facilities would be provided for enclosed waiting, ticketing, an inspectors<br />
office and drivers mess room, lockers, toilet and kitchen. Weather protection in the form of a<br />
covered arcade would be provided to all bus stands.<br />
Taxis<br />
5.26. The present taxi rank is situated within the bus station and is considered problematic and<br />
occasionally dangerous with mixed traffic movements. A new dedicated taxi rank would be<br />
provided adjacent to Usk Plaza which would allow for safe and visible waiting in the evenings and<br />
would be located adjacent to the restaurants, cinemas and the Newport centre.<br />
Cycles<br />
5.27. The proposed development sits adjacent to two major cycle routes north/south along the riverfront<br />
and east/west across the Newport City Bridge. Cycle parking in the form of covered cycle racks<br />
for 70 cycles would be provided within Usk Plaza, Upper Dock Street and the car park set within<br />
the public realm.<br />
Public Realm<br />
5.28. The proposed public realm is designed to perform a number of functions including to:<br />
Create dynamic new public squares and civic spaces;<br />
Appropriately link to and focus on the river corridor;<br />
Provide varied public spaces with differing scale, character and function;<br />
Create attractive and accessible spaces that are hospitable and safe;<br />
Be well crafted, confidently designed and contemporary in character to reflect the ambition of<br />
the city; and<br />
Provide the opportunity to introduce trees and softer vegetation into the built environment.<br />
Friars Walk, Newport,<br />
Chapter 5: The Development - Page 5
5.29. The new public realm would be predominantly pedestrianised and would create a new hierarchy<br />
of linked spaces. These key places are discussed below:<br />
John Frost Square<br />
5.30. As one of the Newport’s main civic spaces, John Frost Square is a key space for pedestrian<br />
gathering and, importantly, a transition between Commercial Street, Upper Dock Street, the<br />
Kingsway Shopping Centre, the Library/ Art Gallery, and, the new development linking to the river<br />
and its dramatic new footbridge. The square, though reduced in size, would consolidate activity<br />
into a more focussed space. A perimeter paved area would be left clear to provide space for an<br />
occasional specialist activity such as specialist markets and events. A central area would be<br />
grassed to provide a green space in the city reflecting the historic Friars Fields. The main<br />
elements of the square would be natural stone paving, clusters of seating and slightly raised<br />
grassed areas. It is not possible to locate trees in John Frost Square as it would be a suspended<br />
slab with limited headroom over the service area.<br />
Friars Walk – covered street<br />
5.31. This covered street would form the spine of the Development. It would be covered by a glazed<br />
roof with a high quality natural granite pavement with ceramic or granite pattern highlights and<br />
artwork incorporated in designated areas.<br />
Usk Plaza<br />
5.32. The new plaza would be substantially laid out in natural and reconstituted stones and the layout<br />
would incorporate the potential for the restaurants to spill out into this area with external seating<br />
and smoking areas, and incorporating contemporary street furniture. A grand feature stair would<br />
be a key component within the Plaza providing seating and ‘people watching’ opportunities. The<br />
external lighting of the plaza would complement the adjoining architecture.<br />
Kingsway West Boulevard<br />
5.33. The new building would reinforce the boulevard nature of Kingsway with proposed roadside semimature<br />
trees planted, new pavements constructed and a new lighting scheme installed. Areas<br />
adjacent to the new Boulevard, notably the Bus Station frontage proposed on Kingsway would<br />
reflect the primary elements of the Kingsway scheme including paving type/layout, tree and shrub<br />
planting and street furniture.<br />
The Lanes – Upper Dock Street, Austin Friars, Friars Street and Llanarth Street<br />
5.34. As part of the overall scheme the historic alignment of Austin Friars would be reopened as a direct<br />
link between Commercial Street and Upper Dock Street and the entrance to Friars walk. In<br />
addition, the extension of Upper Dock Street through to the reconfigured John Frost Square would<br />
be opened up as high quality street parallel to the proposed Friars Walk. The public realm<br />
proposals for this street and other connecting side streets would be simple and bold, focussing on<br />
high quality design and materials. Llanarth Street and Friars Street are already repaved in natural<br />
stone with brass street name inlays. Austin Friars however would be repaved continuing the<br />
quality and paving principles of Friars Walk through to Commercial Street. This area would usea<br />
combination of dark/light natural stone and ‘conservation’ style concrete pavement products,<br />
contemporary style street furniture and an integrated approach to planting including the use of<br />
semi mature tree planting.<br />
Friars Walk, Newport,<br />
Chapter 5: The Development - Page 6
Public Art<br />
5.35. Public Art would be commissioned at detailed design stage to involve both local and national<br />
artists. Areas have been identified within the public realm design to accommodate the detailed<br />
briefs for the incorporation of artwork. The local themes of the Chartist Movement, the maritime<br />
history of the wharfs and the Newport ship, the Friary and Friars Fields, the River Usk and its<br />
crossings, and the Ryder Cup 2010 are a number of themes which would be incorporated into the<br />
briefs for key areas of the development, both inside and out.<br />
5.36. The existing artwork of the ‘Bell carrying bull’ would be relocated in John Frost Square. The<br />
‘silver balls’ were a temporary installation for the Ryder Cup and would be replaced by new works.<br />
The Chartist mural is affixed to a building which is now not fit for purpose and Newport City<br />
Council is deciding the most appropriate way of commemorating this work. The ‘Nick of Time’ is<br />
owned by NCC and a suitable replacement location is to be identified.<br />
External Lighting<br />
5.37. A detailed proposal for external lighting would be prepared during detailed design. The scheme<br />
would comprise both building mounted fittings and free standing feature lighting to provide<br />
ambient light, safety lighting and character feature lighting. In particular, Usk Plaza and would<br />
feature in-floor LED strip fittings and low pole mounted fittings to highlight pedestrian routes and<br />
gateways. The central area of Usk Plaza would feature individual LED floor lighting. John Frost<br />
square would feature more significant decorative pole lighting. Feature colour LED lights would<br />
emphasise the leisure buildings adjoining Usk Plaza. External floodlighting would highlight key<br />
elevations including the Kingsway terrace and the department store<br />

6. Development Programme, Demolition and Construction<br />
Introduction<br />
6.1. This Chapter provides an overview of the demolition and construction works associated with the<br />
Development. An indicative construction phasing and programme of works is provided together<br />
with a description of the anticipated construction methodology and activities likely to be<br />
undertaken within the Site. The information presented in this Chapter has been used to inform<br />
the assessment of effects associated with this stage if the development in each relevant technical<br />
chapter.<br />
6.2. This Chapter was prepared by Waterman EED with input from Waterman Structures and<br />
Queensberry Real Estate.<br />
6.3. It is proposed that an <strong>Environmental</strong> Management Plan (EMP) would be prepared and<br />
implemented. This would be discussed and agreed with the relevant officers at Newport City<br />
Council (NCC) following an approval of the planning application. However, an outline of the<br />
content of the EMP is provided in this Chapter. The aim of the EMP is to provide an effective<br />
mechanism to manage and minimise potential environmental effects arising from construction.<br />
6.4. Details of demolition and construction are broad at this stage and may be subject to modification<br />
following further detailed design work.<br />
Indicative Programme and Phasing of Works<br />
6.5. It is estimated the Development would be built over a period of 36 months from the start of the<br />
enabling works to the completion of the internal finishes. For the purposes of the EIA it has been<br />
assumed that demolition works would commence at the end of 2013, with the completion works in<br />
2015. However, it should be noted that the start date is dependent upon the completion of the<br />
legal planning and leasing agreements.<br />
6.6. It is anticipated that demolition and construction would be undertaken in overlapping phases. The<br />
Development would be constructed in a number of phases of construction works. The<br />
sequencing of the construction works on site would be affected by the significant services<br />
diversion works that need to undertaken, bus station works and the demolition and ground<br />
movements that need to be carried out. The anticipated programme of works envisaged at this<br />
stage is provided in Figure 6.1. These indicative phases are as follows:<br />
Enabling Activities<br />
• Phase 1 Pre Works to Jacklyn Dawson building;<br />
• Phase 2 Full site vacant possession achieved;<br />
• Phase 3 Secure and separate Winlan Buildings from Site.<br />
Major Works<br />
• Phase 4 Potters public house works;<br />
• Phase 5 Service diversions and demolition of all structures;<br />
• Phase 6 <strong>Main</strong> building works including bus station;<br />
• Phase 7 Fit out by tenants;<br />
Friars Walk Newport<br />
Chapter 6: Development Programme, Demolition & Construction - Page 1<br />
dEMO
Phase 1<br />
6.7. The improvement works to the Jacklyn Dawson building will precede vacant possession and the<br />
main development. This is a small isolated area of work akin to a minor refurbishment and it will<br />
not cause disruption to other local receptors.<br />
Phase 2<br />
6.8. The entire site including all retail units and the bus station will be vacated completely prior to<br />
major works.<br />
Phase 3<br />
6.9. The Development requires the removal of the rear half of the Winllan (currently occupied by<br />
Iceland) building to ensure minimal disruption. The separation point will be made secure and<br />
waterproof at the earliest possible point. A section of the building will then be removed to<br />
separate the remaining building from that which is to be demolished. The separation ensures<br />
effects of the major works including vibration are not transferred to the Winllan building and<br />
adjoining buildings.<br />
Phase 4<br />
6.10. An area to the rear (north east) elevation of the Potters Public House will be extended as part of<br />
the development work. This will be completed prior to the demolition to a single storey to the<br />
south of the premises.<br />
Phase 5<br />
6.11. After the site is secured and initial enabling works are completed service diversions will be<br />
executed to make the site safe and to ensure continuity of supplies. As the development is<br />
located on a fully developed site, demolition works are required over the entire site.<br />
Phase 6<br />
6.12. This phase encompasses the major building works. The Applicant will ensure that only<br />
contractors with the required skills and experience will be invited to tender for this scheme. As<br />
part of the procurement period contractors detailed programme proposal will be sought. The<br />
contractor will be required to produce a complete detailed working methodology that will be<br />
subject to analysis and consultation with the local authority.<br />
Phase 7<br />
6.13. During the major works the fit out of the individual retail units will commence as early as seven<br />
months prior to the scheme opening. This work will be procured and let by the incoming tenants<br />
themselves. The fit out contractors will be required to work under a constraint document which<br />
will ensure full coordination between contractors’. The Applicant will manage this process very<br />
closely until scheme opening.<br />
Opening of the Bus Station<br />
6.14. It is the intention to open the bus station approximately six months before the full development<br />
opens. The layout of the site and highway layout enable this to be achieved whilst construction of<br />
the main scheme continues. There will be a great deal of planning leading up to the transition.<br />
The construction site boundary will be altered to enable site security and full public use of the bus<br />
station.<br />
Friars Walk Newport<br />
Chapter 6: Development Programme, Demolition & Construction - Page 2<br />
dEMO
<strong>Main</strong> Scheme Opening<br />
6.15. It is intended, at present, that the full scheme will open on a single day including the cinema,<br />
anchor store, retail units and the public car park. A detailed plan to ensure operational readiness<br />
will be agreed with local authorities. The site hoardings will be removed progressively so that the<br />
public will have full unhindered access.<br />
Description of Works<br />
6.16. This section provides a brief description of the likely nature of work and key activities that would<br />
take place during construction of the Development.<br />
Enabling Works<br />
6.17. Prior to any work taking place, secure hoardings would be erected around the perimeter of the<br />
Site. The alignment of the hoardings would reflect the property lines and allow for sufficient<br />
working space and access for plant and equipment.<br />
6.18. Site access arrangements would be dependent on the stage of demolition of construction and<br />
different gate positions would be used to suit the location of works as they progress across the<br />
Site.<br />
6.19. Site compounds would be situated adjacent to entrance gates. Their location would again be<br />
dependent on the location of the works as they progress across the Site. The location of all<br />
existing primary services including gas, electricity, telecoms etc. has already been identified.<br />
There are a number of existing services that pass in close proximity to the proposed building line<br />
along Upper Dock Street. There is an existing BT chamber that needs to be avoided at the end of<br />
Upper Friars. The exact location needs to be determined on site.<br />
6.20. There is an existing Dwr Cymru Welsh Water (DCWW) sewer that currently crosses the site at the<br />
southern end in a west/east direction that needs to be diverted. The proposal is for it to cut<br />
across in a southwest to northeast direction and to connect back into the existing drainage run on<br />
Kingsway at an earlier location. This would need to be coordinated with the structural basement<br />
and foundation arrangement.<br />
6.21. Appropriate asbestos surveys would also be undertaken prior to demolition by an appropriate and<br />
experienced professional to locate and quantify the presence of any asbestos within the buildings<br />
to be demolished.<br />
Demolition<br />
6.22. The Development will involve the demolition of the entire site area including the bus station,<br />
existing Multi-storey car parks and retail units. The ground levels are to be reduced to various<br />
depths across the site to create a new basement car park and service yard area.<br />
6.23. Based on the current land use and previous site history there is a high risk of encountering buried<br />
foundations and below ground obstructions on the Site. It is envisaged that obstructions would be<br />
removed prior to commencement of construction activities.<br />
6.24. The Development is to be built in close proximity to a number of existing properties and services.<br />
These include the Potters pub at the north end of the site, existing services beneath the pavement<br />
along Upper Dock Street and Kingsway and properties along the western and southern edges of<br />
John Frost Square. Further investigations will be required on site as demolition commences to<br />
confirm design assumptions that are being made on these structures prior to the new build<br />
construction commencing.<br />
Friars Walk Newport<br />
Chapter 6: Development Programme, Demolition & Construction - Page 3<br />
dEMO
6.25. There is to be partial demolition and extensive alteration works to the existing Winllan building.<br />
The best record information available to date has been sourced but works will be required to<br />
confirm existing structural form and condition prior to alterations occurring.<br />
6.26. Demolition method statements would be agreed with NCC prior to commencement. It is<br />
envisaged that demolition of existing buildings would be undertaken using hydraulic ‘long-arm’<br />
breaking machines, cutting wheels for concrete, steel structural elements and site welding.<br />
Site Preparation<br />
6.27. Construction of the basement would be preceded by the installation of a retaining wall to the full<br />
basement perimeter or to parts of the Site as dictated by the phasing of the Development. The<br />
retaining walls would be installed within the lines and confined of the existing Site. Formation of<br />
guide trenches would be carried out as necessary.<br />
6.28. A detailed geotechnical and environmental site investigation would be carried out prior to the<br />
excavation works to confirm the level of any contamination encountered and enable detailed<br />
structural design.<br />
Substructure<br />
Department store<br />
6.29. This block has a part basement structure due to it sitting adjacent to the sloping Upper Dock<br />
Street. The basement will be constructed using ‘bottom up’ basement construction techniques.<br />
Retail / Mall / John Frost Square Foundation and substructure design<br />
6.30. This block has a basement of varying depth over its entire footprint. The basement is<br />
approximately 6m deep where it begins at the far west of the site in the service yard area. As the<br />
basement moves eastwards it rises approximately 1m to form the car park level. The basement<br />
will be constructed using ‘bottom up’ basement construction techniques.<br />
Cinema / supermarket Foundation and substructure design<br />
6.31. This block starts at ground floor level. The design of this element has been developed assuming<br />
construction within an open space. Any lift or escalator pits in all areas are to be externally<br />
tanked using a bonded system or constructed using a waterproof concrete. De-watering of the<br />
excavations would be carried out as necessary during construction.<br />
Superstructure<br />
Department store Superstructure<br />
6.32. The department store would be a 3 storey steel frame structure with metal deck slabs. The roof is<br />
to be lightweight metal deck roof on purlins with a concrete decked area capable of carrying plant.<br />
The roof would be constructed generally flat with any nominal falls generated using secondary<br />
purlins, screeds and dense rated polystyrene.<br />
Retail / Mall Superstructure<br />
6.33. Due to the requirements for vehicle movements in the service yard there are a number of transfer<br />
and long span beams required within the ground floor slab. The building would be a steel framed<br />
structure with insitu concrete floor slabs on profiled metal decked slabs.<br />
6.34. The columns are to be steel at all levels. All columns within the service yard and car park are to<br />
be concrete cased for fire and durability reasons.<br />
Friars Walk Newport<br />
Chapter 6: Development Programme, Demolition & Construction - Page 4<br />
dEMO
6.35. There would be a vehicle turning circle within the basement area which would create a span close<br />
to 24m in length. In order to achieve the spans and headroom criteria the column positions need<br />
to be carefully placed.<br />
6.36. The area to the south of this block would support the new John Frost square over. This area has<br />
an external build up and finishes requirement. The mall area is also to be treated as an external<br />
environment with a larger finishes build-up. The mall roof structure is to be supported off the<br />
primary frame columns but over sails the building block lines with open sides.<br />
Cinema / supermarket Superstructure<br />
6.37. The supermarket is to be a single level steel frame. The cinema boxes are to sit within a primary<br />
steel frame shell. There is to be a secondary isolation system for each of the cinema boxes within<br />
the shell for acoustics and vibration issues.<br />
Fit Out<br />
6.38. Finishes and services fit out of the buildings will commence once a level of temporary or<br />
permanent water tightness has been achieved working from the lowest floors upwards.<br />
Materials and Resource Use<br />
Demolition<br />
6.39. At this stage of the design process, it is difficult to accurately quantify the amount of materials<br />
arising from the demolition works. However, the key demolition waste products are likely to be<br />
those listed below:<br />
• Concrete;<br />
• Metal (mainly ferrous metal);<br />
• Ceramics (mainly bricks with small amounts of other ceramics;<br />
• Glass;<br />
• Timber; and<br />
• Gypsum.<br />
Excavation<br />
6.40. As previously noted, basements are proposed within the Development. Excavated materials<br />
include materials removed as part of the piling of foundations for the proposed buildings.<br />
Materials and Resource Use<br />
6.41. Table 6.1 below highlights the likely materials required for the construction of the Development.<br />
No estimates of the volumes of material have been provided for these materials at this stage.<br />

Plant and Equipment<br />
6.42. Consideration has been given to the types of plant that are likely to be used during the demolition<br />
and construction works. The plant and equipment likely to be associated with each key element<br />
of the construction process is set out in Table 6.2.<br />

<strong>Environmental</strong> Management Plan<br />
6.43. Construction works can cause significant environmental impacts and disruption to neighbours if<br />
they are not properly managed. The Applicant is committed to minimising the impacts of the<br />
works and would require all developers and their contractors to implement an EMP for the<br />
construction works. It is anticipated that NCC would condition the preparation and adoption of an<br />
EMP as part of the planning approval. The EMP would set out procedures that would be required<br />
to be adopted to manage the environmental impacts of the works.<br />
6.44. A summary of the anticipated key issues that would be considered by the EMP, and details of<br />
where further information in relation to mitigation can be found within the ES, is provided in Table<br />
6.3.

6.45. The EMP would also detail responsibilities for the developer, the Construction Manager, the<br />
Contractors and Sub-Contractors; housekeeping procedures; requirements for monitoring and<br />
record keeping; and prohibited or restricted operations. Performance targets would be set,<br />
including for energy and water use, and the progress against these targets regularly reviewed.<br />
6.46. The following sections provide further details on working hours, site security, waste management<br />
and materials, and neighbourhood liaison. For further details regarding the additional issues<br />
outlined in Table 6.4, please refer to the relevant technical chapter of the ES.
Hours of Work<br />
6.47. It is anticipated that the working hours for construction would be as set out below, subject to<br />
agreement with NCC prior to the onset of any works:<br />
• 07:00 to 19:00 from Mondays to Saturdays; and<br />
• No working on Sundays and Bank holidays.<br />
6.48. Where it is necessary to carry out specific activities outside of the above working hours,<br />
agreement to out-of-hours working would be sought in advance from NCC. In particular, these<br />
may involve highway works, service diversions, delivery and offloading of abnormal loads.<br />
Site Security<br />
6.49. Hoardings would be erected around areas of the Site under construction and gates would be<br />
manned to prevent unauthorised access. Prior to the commencement of works, security<br />
measures would be reviewed with NCC and the Police in order that an appropriate provision of<br />
security is maintained. All access and egress points would be controlled by security personnel. A<br />
24 hour security presence would be operated at the Site if necessary.<br />
Waste Management and Materials Storage<br />
6.50. A Site Waste Management Plan (SWMP) would be developed by the appointed Principal<br />
Contractor in accordance with current legislation 1 and best practice guidance, for example, from<br />
the Department for Trade and Industry 2 and WRAP 3 . The SWMP would contain details of the<br />
procedure for assessment, separation and storage of waste materials for re-use, recycling or<br />
disposal.<br />
6.51. Waste materials would be generated during all stages of the construction works with major<br />
sources including:<br />
• Geotechnically and / or chemically unsuitable soils (Ref: Chapter 11: Ground Conditions and<br />
Contamination);<br />
• Demolition waste (as outlined in Paragraph 6.44 above);<br />
• Excavated materials;<br />
• Packaging, for example, plastics, pallets, expanded foams etc;<br />
• Off cuts; and<br />
• Waste materials generated from inaccurate ordering, poor usage, badly stored materials, poor<br />
handling, spillage, etc.<br />
6.52. All relevant contractors would be required to investigate opportunities to minimise waste arisings<br />
at source and, where such waste generation is unavoidable, to maximise the recycling and reuse<br />
potential of construction materials. Recycling of materials would largely take place off-site, where<br />
noise and dust are less likely to result in impacts to the occupants of surrounding properties.<br />
6.53. An active waste minimisation programme would be implemented during each phase of the works.<br />
The opportunity to use site won materials with suitable engineering properties for other<br />
construction projects within the surrounding area would be investigated, subject to compliance<br />
with relevant regulations and legislation.<br />
6.54. The destination of all waste or other materials removed from Site would be notified by the<br />
Contractor / Construction Manager for approval (via consultation with the Authorities). Loads<br />
Friars Walk Newport<br />
Chapter 6: Development Programme, Demolition & Construction - Page 8<br />
dEMO
would only be deposited at authorised waste treatment and disposal sites. Deposition would be in<br />
accordance with the requirements of current waste management legislation 4,5,6,7,8,9 .<br />
6.55. To evidence the correct depositing of excavated material and to prevent the occurrence of flytipping,<br />
a docket system would be used. The Contractor / Sub-contractor would operate a<br />
sequentially numbered docket system, to confirm that each load is received at the approved<br />
disposal site. In line with legal requirements, copies of the dockets would be provided to the<br />
nominated manager, and would be available for inspection at the Site. In addition, direct routes<br />
via motorways/main roads to designated tips would be agreed with the sub contractors.<br />
6.56. No burning of construction waste would be permitted.<br />
6.57. In addition to the usual waste associated with a normal construction project, it is also likely that<br />
there would be some contaminated soils requiring removal from the Site as discussed in Chapter<br />
11: Ground Conditions and Contamination.<br />
6.58. The EMP would also require contractors to store materials appropriately to minimise the risk of<br />
damage by weather, vehicles or vandals. Use of a ‘just in time’ approach would be recommended<br />
for deliveries of material to avoid over-ordering and the need for long term storage on-site.<br />
Supplier take-back schemes would also be used where feasible.<br />
Liaison with Neighbours and Newport City Council<br />
6.59. The Principal Contractor or the Construction Manager would be required to undertake the<br />
following:<br />
• Establish a dedicated point of contact and responsibility to deal with issues as they arise. This<br />
would be a named representative;<br />
• Undertake regular dialogue with NCC and the local community;<br />
• Log complaints and respond to them in a timely manner. The required actions would be<br />
different in each specific case, and may involve applying additional controls; and<br />
• Notify NCC and neighbours, where appropriate, in advance of unusual activities or events that<br />
can be anticipated. The relevant activities would be determined by agreement wherever<br />
possible with NCC, once the detailed programme of construction is defined and would include:<br />
- Commencement of construction in certain areas;<br />
- Necessary night time, weekend or evening working of a type which may affect properties;<br />
- Road or footpath closures/diversions and movements of wide loads;<br />
- Actions requiring monitoring by NCC; and<br />
- Work on roads affecting land used by others.<br />

7. Socio-Economics<br />
Introduction<br />
7.1. This Chapter assesses the likely socio-economic impacts and effects of the Development. In<br />
particular it considers the potential effects of the Development on regeneration, employment,<br />
population, local spending and local services.<br />
7.2. The Chapter describes the planning policy context, the methods used to assess the impacts and<br />
the baseline conditions currently existing at the site. Potential effects of the development are<br />
discussed, together with mitigation measures. This Chapter has been prepared by G L Hearn.<br />
Planning Policy Context<br />
National Planning Policy<br />
7.3. National planning policy in Wales is set out in the Welsh Assembly’s document Planning Policy<br />
Wales (PPW) Edition 4 (2011) 1 . This document is supported by a series of Technical Advice Notes<br />
(TANs) which detail guidelines across specific planning areas.<br />
7.4. The document sets out a series of key Assembly Government objectives in a range of planning<br />
areas including sustainability, the economy and retailing in town centres, all of which are of<br />
relevance to the Development.<br />
7.5. Amongst the key policy objectives in the PPW, policies and proposals should:<br />
• Locate developments so as to minimise the demand for travel, especially by private car;<br />
• Promote access to employment, shopping, education, health, community, leisure and sports<br />
facilities and open and green space, maximising opportunities for community development and<br />
social welfare;<br />
• Foster improvements to transport facilities and services which maintain or improve accessibility<br />
to services and facilities, secure employment, economic and environmental objectives and<br />
improve safety and amenity;<br />
• Promote quality, lasting, environmentally-sound and flexible employment opportunities.<br />
7.6. In the context of ‘supporting the economy’, a priority is to enhance economic success of urban<br />
areas and support development within or adjoining the main urban areas.<br />
7.7. In the context of ‘planning for retailing and town centres’, the following are key principles:<br />
• Securing accessible, efficient, competitive and innovative retail provision;<br />
• Promoting established town centres as the most appropriate locations for retailing, leisure and<br />
other complimentary functions;<br />
• Enhancing vitality and attractiveness and viability of town centres; and<br />
• Promoting access to these centres by public transport, walking and cycling.<br />
Economic Renewal: a new direction – July 2010<br />
7.8. Economic Renewal 2 sets out the Welsh Assembly’s strategy for economic development in Wales.<br />
The Strategy identifies key priorities which include the following:<br />
• Investing in high quality and sustainable infrastructure;<br />
• Making Wales a more attractive place to do business;<br />

Regional Planning Policy<br />
Strategic Planning Guidance for South East Wales – January 2000<br />
7.9. Strategic Planning Guidance for South East Wales 3 is produced by the South East Wales Strategic<br />
Planning Group. There are no planning regions in Wales but the Welsh Assembly Government<br />
advises that planning authorities may wish to form voluntary alliances in order to align policy. The<br />
South East Wales group constitutes 11 authorities across the region, including Newport.<br />
7.10. The Guidance sets out a series of recommendations in areas including:<br />
Retail Development<br />
7.11. Recommendation R2 – States that development plans should define the retail hierarchy of<br />
shopping centres in order to identify protect and enhance existing shopping centres.<br />
Urban Regeneration<br />
7.12. Recommendation UR4 – Emphasises the importance of the use of brownfield sites as a key<br />
component of local regeneration strategies.<br />
Five Counties Regeneration Framework: Final Report 2002<br />
7.13. The Five Counties Regeneration Framework 4 covers Blaenau Gwent, Caerphilly, Monmouthshire,<br />
Torfaen and Newport councils. The Framework outlines a vision for 2011: “The Five Counties:<br />
Smart, Successful and Well-connected”<br />
7.14. The Framework describes two possible scenarios for Newport. The first details the likely situation if<br />
regeneration in the area does not occur. The focus of this is the lack of replacement for loss of<br />
employment in traditional industries, including metal manufacturing and the report envisages a<br />
failed City centre with few fashion retailers remaining.<br />
7.15. The preferred scenario is where regeneration ensures that Newport is a major office and retail<br />
location with a wide range of employment opportunities.<br />
7.16. The Framework then identifies four Regeneration Principles:<br />
1. Create a sustainable knowledge-based economy;<br />
2. Establish an integrated and well-connected sub-region;<br />
3. Build a lifelong learning culture; and<br />
4. Re-establish our towns as centres of economic activity.<br />
7.17. The regeneration of the centre of Newport is cited as being central to achieving Principle 4 above.<br />
The report describes Newport as not “punching its weight” as a shopping centre. The Framework<br />
is proposing that “Newport centre becomes a much stronger retailing and office centre”.<br />
7.18. The Framework also sets out components for creating strong communities including accelerating<br />
the regeneration of the Town Centres.<br />

Local Planning Policy<br />
Newport City Council Unitary Development Plan (UDP) 1996-2011 (Adopted May 2006)<br />
7.19. The plan 5 sets out a series of objectives across areas including employment and regeneration.<br />
7.20. One of the Council’s aims is to ensure that there is an adequate supply of land to meet the<br />
employment needs of the population. In addition the Council includes amongst its objectives the<br />
promotion of regeneration opportunities in inner urban areas. Specific policies of relevance are<br />
described below.<br />
7.21. Policy SP17 – Urban Regeneration. The council would favour proposals which assist the<br />
regeneration of the urban area and contribute to the vitality, viability and quality of the environment<br />
of the city centre.<br />
7.22. Policy CE30 – Regeneration. The Policy states that urban regeneration schemes would be<br />
encouraged including those that would result in the reuse of vacant and derelict land and buildings.<br />
7.23. Policy ED4 – Economic Development. The Policy states that in Newport city centre, outside areas<br />
identified as primary shopping frontage appropriate redevelopment would be favoured for<br />
employment, tourism, leisure or a mix of uses which would complement the retailing function and<br />
enhance regeneration opportunities. In reasoned justification the UDP states that large scale<br />
leisure related developments such as multiplex cinemas would be acceptable at appropriate city<br />
centre locations. It is important, however, that any leisure uses in particular are compatible with<br />
criteria listed in Policies R4 and R5 which deal with the presence of non-retail uses within shopping<br />
areas.<br />
7.24. Policy SP18 – Retailing. The Policy states that proposals in or adjoining the city centre would be<br />
permitted where they enhance the retail function and are of an appropriate scale. A key objective<br />
of the Plan is to maintain and strengthen the vitality, functioning and attractiveness of Newport city<br />
centre as a major regional shopping destination.<br />
7.25. Policy R1 – Retailing. The Policy favours redevelopment schemes involving enhanced provision of<br />
retail facilities within the city centre shopping area provided that the scale, design and layout of the<br />
proposals are compatible with the overall function of the centre and the visual environment. In<br />
reasoned justification to the policy, paragraph 6.7 states that...”A major city centre retail scheme is<br />
being promoted in the John Frost Square area to provide a department store, other retail units, new<br />
car parking and related facilities. This would be a significant element of the strategy to enhance<br />
the city centre, which would be carried forward in the city centre Masterplan”.<br />
7.26. Policy CF12 – Leisure. The Policy sets out criteria for the consideration of new leisure<br />
developments. These include that where an indoor use is proposed, the site should be located<br />
within the defined urban area, and should preferably be supportive of urban regeneration<br />
intentions.<br />
Preferred Strategy - Newport Local Development Plan 2011 – 2026<br />
7.27. Newport City Council consulted during 2010 on the Preferred Strategy for the Newport Local<br />
Development Plan 6 . The draft Plan is yet to be adopted but is scheduled to replace the UDP in<br />
2013. The draft Plan’s vision is as follows:<br />

“As a gateway to Wales, Newport will be a centre of regeneration that celebrates its culture and<br />
heritage, while being a focus for diverse economic growth that will strengthen its contribution to<br />
the region. It will be a place that people recognise as a lively, dynamic, growing city, with<br />
communities living in harmony in a unique natural environment.”<br />
The draft Plan states that regeneration is the key means of achieving sustainable development in<br />
terms of environmental, social and economic aspects. The reuse of resources and in particular<br />
land, buildings, physical and social infrastructure is an aspiration and ‘Sustainable Use of Land’ is<br />
Objective 1 in the draft Plan.<br />
Economic Growth is Objective 3 and it seeks “To enable a diverse economy that meets the needs<br />
of the people of Newport and those of the wider South East Wales economic regions.” In particular<br />
the strategy seeks to maintain Newport’s role as major economic hub in the region, providing<br />
employment and adding value. Inner urban sites would be a focus.<br />
Newport Unlimited – Urban Regeneration Company (URC)<br />
7.28. Newport Unlimited is the urban regeneration company for the city, founded by the Welsh Assembly,<br />
Welsh Development Agency and Newport City Council. The URC aims to encourage economic<br />
development in Newport through regeneration, and has the aim of re-establishing Newport’s role in<br />
regional economic growth.<br />
7.29. A series of masterplans have been produced by the URC, including one for central Newport – ‘The<br />
‘Newport 2020: Unlimited Vision’ Central Area Master Plan 7 ’. Described as a “once in a generation<br />
opportunity for the city to create a better quality of life for its residents”, the Masterplan constitutes<br />
several ‘Priority Areas’ including the city centre commercial core. The Masterplan supports the aim<br />
of having an anchor store and improved retail around John Frost Square and in addition, mixed use<br />
development including housing and leisure uses.<br />
Newport Regeneration Programme – Final Report – February 2002<br />
7.30. This document is similar to the Five Counties Regeneration Framework identified above, but with a<br />
specific focus on Newport.<br />
7.31. The Programme 8 identifies six ‘Regeneration Principles’ to guide collaboration between the<br />
Council, the Welsh Development Agency and Education and Learning Wales (ELWa). These are<br />
to:<br />
• Create a more diversified economic base;<br />
• Reinforce Newport as an economic engine;<br />
• Establish the town centre as an attractive retail and business location – an urban renaissance;<br />
• Establish Newport as a centre for logistics; and<br />
• Ensure that all share in Newport’s prosperity.<br />
Newport Economic Development Strategy 2008-2011<br />
7.32. This report 9 establishes Newport City Council’s three year economic development strategy to<br />
coincide with end of the Unitary Development Plan in 2011.<br />
7.33. The Strategy outlines a series of key actions which include: bringing forward key development<br />
sites; delivering key regeneration projects across the city; and, tackling economic inactivity.<br />

Newport City Centre Masterplan – draft Supplementary Planning Guidance (SPG) July 2004<br />
7.34. The city centre Masterplan 10 sets out a development framework for the central area including<br />
policies for creating a more vibrant and liveable city centre. The document places an emphasis on<br />
mixed use development and “infill in an expanded city centre”.<br />
7.35. Proposals include allocating large sites for department stores and larger unit size shops to achieve<br />
“a wider variety of retailing”. In addition, mixed use in the centre is encouraged, with apartments<br />
over shops bringing new population to the centre. Improving connectivity and the quality of open<br />
space is also emphasised.<br />
Newport’s Community Strategy 2010 - 2020 – Feeling good about Newport<br />
7.36. The Strategy 11 sets out the Local Service Board’s vision over the next 10 years.<br />
7.37. The Strategy’s priority outcomes for a prosperous and thriving city are as follows:<br />
• Newport has a prosperous and thriving economy;<br />
• More people in Newport participate in the local economy;<br />
• Newport reduces its carbon emissions and resource consumption; and<br />
• Newport is a distinctive and vibrant place.<br />
7.38. The Strategy’s priority outcomes for a better quality of life are as follows:<br />
• People in Newport are healthy and thriving;<br />
• Children in Newport have the best start in life;<br />
• Children and young people in Newport succeed in school or work; and<br />
• Adults in Newport are successful and realise their potential.<br />
7.39. Priority outcomes for vibrant and safe communities are:<br />
• People in Newport live in a safe and inclusive community;<br />
• People in Newport live in a clean and pleasant environment;<br />
• People in Newport experience diverse wildlife, countryside and open spaces; and<br />
• People in Newport are involved in community life and local decision making.<br />
Assessment Methodology and Significance Criteria<br />
Assessment Methodology<br />
7.40. The baseline analysis reviews the socio-economic conditions at the Site and in the surrounding<br />
area. It uses accepted Government data sources (Census of Population, Labour Force Survey,<br />
NOMIS) and reviews current uses on the Site.<br />
7.41. The site is in Stow Hill ward, in the centre of Newport between the river and the main shopping<br />
district, bordered by a mix of uses including retail, office, and parking.<br />
7.42. For the purposes of assessing the existing socio-economic conditions in the area, data has been<br />
compared for four geographical areas:<br />
• Stow Hill (the ward in which the development is located);<br />
• Newport;<br />
Friars Walk, Newport<br />
Chapter 7: Socio-Economics - Page 5<br />
Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.07 Socio-Economics\EED12300_Ch 07_Socio-Economics_091211.docx
• The Five Counties area (Blaenau Gwent, Caerphilly, Monmouthshire, Torfaen and Newport);<br />
and<br />
• England and Wales.<br />
7.43. Construction impacts have been assessed using ratios of construction employment to output,<br />
assuming an average output per employee of £110,660 based on average turnover per<br />
construction sector employee in 2008. There is a convention that 10 temporary construction jobs<br />
are equivalent to 1 Full Time Equivalent (FTE) job. An additional multiplier of 1.25 is applied to the<br />
FTE construction employment to provide an estimate of indirect/induced jobs that could be<br />
supported in the local area or as supply chain linkages within the region as a result of such<br />
construction related expenditure.<br />
7.44. Employment densities for commercial floor space developed by the Homes and Communities<br />
Agency 12 of 19 sq m per retail (17 sq m for food store) and 18 sq m per restaurant job (based on Net<br />
Internal Area (NIA)) and 90 sq m per cinema job (based on Gross Internal Area (GIA)).<br />
7.45. Expenditure from workers in the new development has been estimated at £6 per day based on<br />
YouGov 13 and based on 236 working days per year.<br />
7.46. As no residential development is proposed the impact upon housing, population, education and<br />
healthcare is considered negligible and is therefore not considered in this assessment.<br />
Significance Criteria<br />
7.47. There are no technical significance criteria relating to socio-economic impacts. The significance of<br />
socio-economic impacts is therefore considered in the context of their overall impact on the<br />
immediate surroundings and the wider neighbourhood in the context of policy guidance and<br />
baseline conditions.<br />
7.48. Significance has been assessed as substantial, moderate, or not significant, and as either positive<br />
or negative in its impact. In terms of spatial scope, impacts are considered at the local (ward),<br />
district (Newport) and regional (five counties) levels.<br />
Baseline Conditions<br />
Education and Economic Activity<br />
7.49. Across Newport, 74.2% of the population were economically active in 2010-11 14 , which is above<br />
the average for the Five Counties (72.2%) and Wales (72.5%) although below average for England<br />
and Wales (76.1%). The employment rate (as a proportion of the population aged 16-64) is 66.5%.<br />
7.50. Economic inactivity has increased over the last five years, by 1.1 percentage points in Newport, to<br />
25.8% of the population aged 16-64 in 2010-11. This is greater than the increase across Wales<br />
and England and Wales, although slightly more moderate than across the Five Counties. This is<br />
likely to have been influenced by macro-economic trends.<br />
7.51. Over this period unemployment has also grown. Unemployment in Newport in 2010-11 at 10.4% of<br />
the population aged 16-64 is above the national average (for both Wales at 8.6% and England and<br />
Wales at 7.7%), as well as the average for the Five Counties (9.4%). It has increased more<br />
strongly than has been the case nationally over the last four years, as Figure 7.2 indicates.<br />
7.52. Job Seekers Allowance (JSA) Claimants are a subset of overall unemployment. The JSA Claimant<br />
Count in Stow Hill ward in October 2011 was 8.6% (as a proportion of the population aged 16-64).<br />
This was the 3 rd highest of the 20 wards in Newport, and significantly above wider averages of<br />
Friars Walk, Newport<br />

Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.07 Socio-Economics\EED12300_Ch 07_Socio-Economics_091211.docx
5.3% for Newport as a whole, and 4.0% across Wales. There is an evident strong concentration of<br />
unemployment in central Newport.<br />
7.53. Figure 7.3 profiles the occupations of those claiming Job Seekers Allowance across Newport (and<br />
compares this to Wales as a whole). There were 1,210 unemployed claimants seeking jobs in<br />
sales and customer service occupations, 1515 in elementary occupations and 345 in skilled trades<br />
in October 2011.<br />
7.54. Considering the overall occupational profile of Newport residents in employment in the Annual<br />
Population Survey, relative to Five Counties there are a high level of people employed in<br />
managerial and professional occupations and administrative and secretarial occupations.<br />
Local Deprivation<br />
7.55. The Welsh Index of Multiple Deprivation (IMD) 2011 was published by the Assembly Government<br />
this year. This index aggregates a wide range of data sources to compile an index showing the<br />
relative deprivation of an area. Stow Hill 3, the Lower-Level Super Output Area (LSOA) which<br />
includes the site is identified in Figure 7.4 and the findings of the latest IMD for Stow Hill 3 are<br />
shown in Figure 7.5. Deprivation is benchmarked relative to other LSOAs across Wales.<br />
7.56. The local area which includes the development site falls within the most deprived 15% of areas in<br />
Wales. Deprivation is particularly severe in regard to the physical environment (within the 5% most<br />
deprived areas), and employment (10% most deprived areas). In contrast the area demonstrates<br />
good access to services.<br />
Potential Effects<br />
Demolition and Construction<br />
7.57. The Site clearance and demolition would result in the temporary loss of local spending, existing<br />
jobs on site and local retail convenience. These effects would have temporary local effect of<br />
moderate adverse significance with negligible effects at district and regional levels.<br />
7.58. The construction phase has the potential to generate significant levels of employment. Using<br />
typical figures for the gross output per employee for the construction sector (£110.660 as noted in<br />
the methodology section of this Chapter) and estimated construction costs (£90m), the<br />
Development could be expected to create 814 person years of employment. By convention, a<br />
permanent full time equivalent (FTE) job is equated to 10 person years of employment which gives<br />
an overall figure of around 81.4 permanent FTE jobs from construction. This is likely to translate<br />
into a significantly higher headcount on-site over the duration of the construction period, with<br />
different levels and types of employment depending on the stage of the development programme.<br />
7.59. Additionally the construction related expenditure on the site is likely to generate indirect/induced<br />
jobs in the local area. We calculate this by applying a multiplier of 1.25 to the construction phase<br />
FTE figure, thus generating an estimate of indirect/induced jobs 20 FTE. The effect of construction<br />
phase employment would be a short term moderate beneficial effect at local and district level<br />
and negligible effect at regional level.<br />
Completed Development<br />
7.60. Based on standard floorspace per job ratios as set out by the Homes and Communities Agency<br />
(HCA), Table 7.1 below shows the estimated employment created through commercial end uses in<br />
the development proposal. The total number of FTE jobs generated by the proposal is estimated to<br />

e 1,342. It is likely that many of these FTE jobs would be available as part time positions (i.e.<br />
where a number of part time posts add up to one FTE) which means the total number of people<br />
employed could be significantly higher.<br />
7.61. Due to the nature of the retail and leisure sectors which often operate into the evening and over<br />
weekends, the types of jobs opportunities available would include flexible and part time working<br />
patterns that are often attractive to parents or students seeking flexible employment hours.<br />

*Management element is the management suite and includes employment of management, security and cleaning staff.<br />
Overall employment generation<br />
7.62. The total number of gross jobs (FTE) created by the construction phase and completed<br />
development could be expected to be up to a maximum of 1,423.4.<br />
7.63. It should be noted that the existing bus station operations are being reprovided, however, the bus<br />
station would continue to operate during the construction phase (when rescheduled) and when<br />
opened the new bus station would be significantly larger than existing and could generate<br />
additional jobs in the future should services increase.<br />
7.64. The Development would provide employment opportunities which are significantly lacking in the<br />
Stow Hill ward as set out in the IMD findings which indicated that this area is within the worst 10%<br />
of areas in Wales for employment.<br />
7.65. There would be opportunities to recruit local people in such construction related jobs and typically<br />
these would be recruited from the ‘elementary’ skills sector which is identified as the sector<br />
attracting the highest volume of JSA claimants in Newport.<br />
7.66. The retail and service sector jobs that would be created specifically address a need that is<br />
identified in JSA claimant figures for Newport where ‘Sales and Customer Service’ is the second<br />
highest claimant sector at more than 25%.<br />
Displacement<br />
7.67. The construction of the development would require the replacement of existing commercial<br />
floorspace, which would displace some existing jobs. It should be noted that these jobs are not<br />
necessarily lost to the economy as some would relocate elsewhere in the city. Displacement is<br />
estimated in Table 7.2.<br />
Friars Walk, Newport<br />
Chapter 7: Socio-Economics - Page 8<br />

Table 7.2: Job Displacement (existing floorspace to be replaced)<br />
Displaced Floorspace Floorspace/Job ratio Displaced Jobs<br />
A1 Retail 3,884 NIA 19 204.5<br />
A2 Financial Services 400 NIA 16 21<br />
Restaurant & Pub 134.6 NIA 18 7<br />
Total 232.5<br />
7.68. Taking into account the displacement, the development can be expected to create a net additional<br />
1,109 FTE jobs.<br />
7.69. Construction employment is relatively mobile and it is not particularly meaningful to consider its<br />
impact at a local level in terms of displacement. Overall the employment impact of the construction<br />
phase would be positive and negligible at the district and regional levels.<br />
7.70. The employment effect of the development would bring a net increase in jobs and is therefore<br />
considered to be a long term, local and district effect of substantial beneficial significance and<br />
moderate beneficial significance at regional level.<br />
Expenditure<br />
7.71. The increase in employment is likely to result in a significant increase in expenditure in the local<br />
area. A YouGov Survey in 2005 estimated that workers spend an average of £6 per day on food<br />
and drink. Based on 1,109 jobs, this equates to additional expenditure of £1,570,344 per annum<br />
within the local economy. Long term effect of substantial beneficial significance at local and<br />
district level and negligible significance at regional level.<br />
Broader Regeneration Impacts<br />
7.72. The Policy Review section of this Chapter makes clear that a key objective of local policy is to use<br />
the revitalisation of the city centre as a focus for the regeneration of Newport. This scheme is a<br />
key component of the city centre’s improvement and has significant broader impacts beyond the<br />
direct employment benefits.<br />
7.73. The application meets many of the policy objectives set out above, including providing a site for a<br />
department store and a wider variety of retailing in a high quality, accessible and attractive setting.<br />
This would improve retail choice and help increase footfall and general vitality within the local area<br />
and the town centre more widely.<br />
7.74. The development also includes a new cinema which brings a new leisure activity which is currently<br />
lacking within Newport city centre. This contributes towards the objectives of bringing people to<br />
live in the city centre and supporting the leisure and tourism offer of Newport.<br />
7.75. A Retail Assessment (Appendix 7.1) has been provided to support the planning application and this<br />
confirms that the Development can be expected to substantially raise the vitality, attractiveness and<br />
viability of the city centre, as well as drawing pedestrians through John Frost Square and linking<br />
the rest of the city centre with the riverside walk and arts centre. The mix of uses including retail,<br />
cinema and restaurants, should encourage greater pedestrian activity throughout the day and<br />
evening, improving perceptions of personal safety.<br />
7.76. This broader regenerative impact is more difficult to quantify (other than the direct employment<br />
benefits). The existing Site is partially vacant and derelict. The Site’s reuse would improve the<br />
attractiveness and prosperity of the area and contribute towards policy objectives for the reuse of<br />
vacant sites and premises. It is considered that the development can be expected to have a Long<br />

term, local and district effect of substantial beneficial significance and moderate beneficial<br />
significance at regional level.<br />
Mitigation<br />
Demolition and Construction<br />
7.77. The Site clearance and demolition would result in a temporary loss of local spending and<br />
temporary loss of local retail convenience. This would be mitigated for by the new and improved<br />
offer of significantly enhanced retail provision.<br />
7.78. The temporary construction phase employment would have Short term moderate beneficial effect<br />
at local and district level and negligible effect at regional level.<br />
Completed Development<br />
7.79. Employment benefits would result in a net increase in employment provision. No mitigation is<br />
required. It has been demonstrated that employment opportunities correlated with the most<br />
popular employment sectors in JSA claimants and therefore local labour should benefit from such<br />
opportunities. All of the effects of the completed development are beneficial and require no<br />
mitigation.<br />
Residual Effects<br />
Demolition and Construction<br />
7.80. The site clearance and demolition would result in the displacement of existing jobs and a temporary<br />
loss of local spending and temporary loss of local retail convenience. This would be mitigated for<br />
by expenditure from construction workers and in future by the new and improved offer of<br />
significantly enhanced retail provision. These effects have a negligible residual effect.<br />
7.81. The construction phase employment is a short term moderate beneficial effect at local and district<br />
level and negligible effect at regional level.<br />
Completed Development<br />
7.82. In socio-economic terms the Development is in line with policy. It would provide a net increase in<br />
employment that would be long term, local and district effect of substantial beneficial<br />
significance and moderate beneficial significance at regional level.<br />
7.83. Additional expenditure from employees of the scheme would be a long term effect of substantial<br />
beneficial significance at local and district level and negligible significance at regional level.<br />
7.84. Regenerative effects would be beneficial and include significantly improving the retail and leisure<br />
offer; and, contributing towards the regeneration of the town centre and Newport as a whole.<br />
Overall the regenerative impact of the scheme is expected to be a long term substantial<br />
beneficial effect at local and district levels and a moderate beneficial effect at regional level.<br />

8. Transportation and Access<br />
Introduction<br />
8.1. This Chapter, which was written by Ove Arup and Partners Ltd, provides an assessment of the<br />
likely significant transport and access related effects of the Development.<br />
8.2. The Chapter describes the baseline transport conditions within and in the vicinity of the Site, the<br />
assessment methodology used to forecast the trip generation and the potential direct and indirect<br />
effects of the Development on all transport modes. Changes to highway traffic volumes, flows and<br />
capacity, and the effects on public transport accessibility and capacity are addressed, together with<br />
consideration of the temporary effects arising from demolition and construction activities. Any<br />
mitigation measures required to prevent or reduce any adverse effects arising from the<br />
Development are also discussed, as are the likely resultant residual effects.<br />
8.3. This Chapter summarises the results of the Transport Assessment (TA) for the Development which<br />
is provided as Technical Appendix 8.1 (<strong>Volume</strong> 3b) of this <strong>Environmental</strong> <strong>Statement</strong>.<br />
Planning Policy Context<br />
8.4. This section outlines the national, regional and local transport policy context within which the<br />
Development must be assessed.<br />
National Planning Policy<br />
Planning Policy Wales: Edition 4 (February 2011)<br />
8.5. Planning Policy Wales (PPW) 1 sets out the land use planning policies of the Welsh Government. It<br />
is supplemented by a series of Technical Advice Notes (TANs).<br />
8.6. Chapter 8 (‘Transport’) of PPW identifies choice in transport and secure accessibility as important<br />
in supporting sustainable development and tackling the causes of climate change. The application<br />
of a transport hierarchy that prioritises the needs of pedestrians, cyclists and public transport users’<br />
forms part of an integrated approach to land use planning that can assist in achieving a range of<br />
key transport objectives. These include the following:<br />
• reducing the need to travel, especially by private car, by locating development where there is<br />
good access by public transport, walking and cycling;<br />
• locating development near other related uses to encourage multi-purpose trips and reduce the<br />
length of journeys;<br />
• improving accessibility by walking, cycling and public transport;<br />
• ensuring that transport is accessible to all, taking into account the needs of disabled and other<br />
less mobile people;<br />
• promoting walking and cycling;<br />
• supporting the provision of high quality public transport;<br />
• supporting traffic management measures;<br />
• supporting necessary infrastructure improvements; and<br />
• ensuring that, as far as possible, transport infrastructure does not contribute to land take, urban<br />
sprawl or neighbourhood severance.<br />

8.7. Chapter 10 (Planning for Retail and Town Centres) highlights how there is a need for good access<br />
to town centres for walkers, cyclists and public transport. A choice of transport opportunities,<br />
coupled with the co-location of retail and other services, can provide the greatest benefit to<br />
communities. The needs of people with limited mobility and delivery vehicles should also be<br />
catered for. Access by car and short-term parking is recognised as important in competing with<br />
existing out of centre locations.<br />
Technical Advice Note 18: Transport (March 2007)<br />
8.8. TAN 18 2 elaborates on the relationship between land use planning and transport infrastructure by<br />
outlining a range of key accessibility principles that should inform future patterns of development.<br />
The need for major trip-generating development to be situated in central locations close to public<br />
transport interchanges is seen as key to reducing car dependency and promoting social inclusion.<br />
8.9. The following principles are cited as critical in achieving wider sustainable development objectives:<br />
• promoting resource and travel efficient settlement patterns;<br />
• ensuring new development is located where there is, or will be, good access by public transport,<br />
walking and cycling, thereby minimising the need for travel and fostering social inclusion;<br />
• managing parking provision;<br />
• ensuring that new development and major alterations to existing developments include<br />
appropriate provision for pedestrians (including those with special access and mobility<br />
requirements), cycling, public transport, and traffic management and parking / servicing;<br />
• encouraging the location of development near other related uses to encourage multi-purpose<br />
trips;<br />
• promoting cycling and walking;<br />
• supporting the provision of high quality, inclusive public transport;<br />
• encouraging good quality design of streets that provide a safe public realm and a distinct sense<br />
of place; and<br />
• ensuring that transport infrastructure or service improvements necessary to serve new<br />
development allow existing transport networks to continue to perform their identified functions.<br />
8.10. TAN 18 also highlights how concentrating development around existing or new transport<br />
interchanges can provide a focus for accessible and sustainable development.<br />
8.11. TAs should be secured for developments that generate significant levels of movement or are likely<br />
to have a significant effect on patterns of movement. The proposed scale of development at Friars<br />
Walk exceeds the specified thresholds denoting when a TA is required.<br />
Wales Spatial Plan (July 2008 Update)<br />
8.12. The 2008 update to the Wales Spatial Plan (WSP) 3 sets out the planning agenda at a spatial level.<br />
There are five guiding themes which underpin the national vision:<br />
• building sustainable communities;<br />
• promoting a sustainable economy;<br />
• valuing our environment;<br />
• achieving sustainable accessibility; and<br />
• respecting distinctiveness.<br />

8.13. For the South East Wales – Capital Region, a level of connectivity that aids the movement of goods<br />
and people, and encourages sustainable transport choices, is identified as a measure of future<br />
success. Newport forms one of the key regional settlements, where regeneration through high<br />
quality development is expected to befit its role within the capital region. Among the key supporting<br />
priorities are to reduce traffic congestion and develop effective public transport.<br />
National Transport Plan (July 2009)<br />
8.14. The National Transport Plan (NTP) 4 provides a basis for taking forward the delivery of the<br />
integrated transport strategy proposed with the Wales Transport Strategy. The NTP includes a<br />
number of aims that are intended to maximise the benefits associated with improving transport.<br />
Those relevant to the east-west corridor in South Wales include the following:<br />
• continuing to develop the most appropriate, and sustainable, solutions to transport issues in<br />
South East Wales; and<br />
• improving reliability, journey time and safety along the east-west road corridor.<br />
Wales Transport Strategy: One Wales – Connecting the Nation (April 2008)<br />
8.15. In informing the strategic priorities of the NTP, the Wales Transport Strategy 5 identifies a range of<br />
outcomes that should be achieved over the longer term. These include the need for improved<br />
connectivity and reliability across networks. The following key principles are identified as critical to<br />
the future transport policy agenda:<br />
• achieving a more effective and efficient transport system;<br />
• achieving greater use of the more sustainable and healthy forms of travel;<br />
• minimising demands on the transport system; and<br />
• reducing the effect of transport on greenhouse gas emissions.<br />
8.16. Among the range of intended strategy outcomes is improved access to shopping and leisure<br />
facilities, which is highlighted as requiring good quality public transport.<br />
Regional Planning Policy<br />
Regional Transport Plan (March 2010)<br />
8.17. The Regional Transport Plan (RTP) 6 , prepared by the South East Wales Transport Alliance<br />
(SEWTA), provides the regional framework from which to deliver the objectives of the WSP and<br />
NTP.<br />
8.18. It is founded on a vision framed around the following key priorities:<br />
• develop the economy, through improving connectivity for business and freight, making transport<br />
more effective and efficient, providing access to employment, education, shopping and leisure,<br />
and by improving transport integration;<br />
• promote social inclusion and equality, by providing a transport system that is safe, accessible,<br />
and affordable to all sections of the community; and<br />
• protect the environment, by minimising transport emissions and consumption of resources and<br />
energy, by promoting walking, cycling, quality public transport, modal shift and minimising<br />
demand on the transport system.<br />
8.19. The strategy outlines the activities and interventions that would form part of a balanced approach to<br />
tackling the key priorities. Chapter 4: The Preferred Strategy identifies the role that new<br />

Access\ES Chapter 8 Transportation Access _JD_BW_003_JD - Final.docx
development is expected to play in improving transport networks. Planning policy PLP5<br />
encapsulates this as follows:<br />
“SEWTA supports the transport elements of regeneration and development programmes where<br />
they are to the benefit of RTP objectives, make provision for pedestrians, cyclists and public<br />
transport and do not adversely affect the operations of the highway network.”<br />
8.20. It is also notable that the RTP ‘Integration, Interchange and Information’ commitments include<br />
Policy IIP1 regarding public transport interchanges:<br />
“SEWTA supports further improvements and expansion of public transport interchanges and<br />
Park and Ride facilities.”<br />
8.21. Schemes identified for inclusion in future capital programmes include the following:<br />
• Newport Area Signalling Renewal Scheme (rail);<br />
• Newport City Centre Regeneration (public transport interchange proposals); and<br />
• Old Green remodelling.<br />
Local Planning Policy<br />
The Local Development Plan for Newport: Preferred Strategy (January 2010)<br />
8.22. The Local Development Plan (LDP) 7 , once formally adopted, will provide the development strategy<br />
and spatial policy framework for the County Borough over the period to 2026.<br />
8.23. Paragraph 2.113 highlights how “accessible, efficient, competitive and innovative retail provision is<br />
sought, together with promotion of access by public transport, walking and cycling”.<br />
8.24. These principles are reinforced in Policy SP1, which requires new development to make a positive<br />
contribution to sustainability by achieving the following:<br />
“ii) providing integrated transportation systems, as well as encouraging the co-location of housing<br />
and services, which together will minimise the overall need to travel, reduce car usage and<br />
encourage a model shift to more sustainable modes of transport.”<br />
8.25. Policy SP11 states that transport proposals will be supported where they achieve the following:<br />
“i) a co-ordinated pedestrian network, including schemes such as ‘Safe Routes in Communities’<br />
ii) implementation of the cycling strategy<br />
vi) appropriate provision for public transport operation at the planning stage of new developments<br />
viii) facilities for public transport, walking and cycling in major new development.”<br />
Newport Unitary Development Plan (May 2006)<br />
8.26. The adopted Unitary Development Plan (UDP) 8 continues to form a statutory basis for planning<br />
decision making until such time that the new LDP comes into force.<br />
8.27. In Chapter 4 (Transport and Communication) the UDP is underpinned by the following objectives:<br />
• To maintain and improve accessibility for all sections of the community and for all modes of<br />
transport to and within Newport, consistent with its sub-regional role;<br />
• To support transport schemes which benefit the economy of the County Borough and the living<br />
standards of its people;<br />
Friars Walk, Newport<br />
Chapter 8: Transportation and Access - Page 4<br />

Access\ES Chapter 8 Transportation Access _JD_BW_003_JD - Final.docx
• To minimise adverse effects of traffic and parking on people and the environment and to<br />
consider the mobility and access requirements of special needs groups;<br />
• To support and enhance public transport and non-car modes of transport, and to work towards<br />
the integration of all modes of transportation.<br />
8.28. These are reflected in Policy T7, which is geared towards ensuring the implications of development<br />
on transport can be suitably accommodated:<br />
“Developments that have an unacceptable adverse effect on the transportation system will not<br />
be permitted. Where objections can be overcome by improvements to the transport system, a<br />
contribution will be sought from the developer under statutory provisions.”<br />
8.29. Policy R2 highlights how improved retail facilities in the central shopping area will be supported<br />
subject to the following:<br />
“ii) free movement of pedestrians and operational requirements would not be unacceptably<br />
adversely affected.”<br />
Assessment Methodology and Significance Criteria<br />
Assessment Methodology<br />
8.30. The assessment methodology incorporates many of the established principles that were included in<br />
the original TA (dated March 2006) submitted in support of the approved Modus Corovest<br />
(Newport) Ltd planning application. It also reflects the agreed outcomes of discussions with<br />
Newport City Council as local highway authority.<br />
8.31. The following methodology was used to determine the baseline conditions on the local transport<br />
networks:<br />
• Traffic count surveys – Traffic counts were undertaken at each of the road junctions within the<br />
study area over a neutral period, 3rd and 5th November 2011, to ensure that the data collected<br />
typify network conditions. Each count covered the principal periods of travel demand on the<br />
network, namely 07:30 to 09:30 and 16:30 to 18:30 on a weekday and 11:30 to 13:30 on a<br />
Saturday;<br />
• Personal Injury Accident (PIA) Analysis – Personal Injury Accident (PIA) data for the period<br />
September 2006 to August 2011 was obtained for all of the junctions in the study area;<br />
• Desk study – a desktop study was undertaken to identify local facilities and current levels of<br />
public transport provision;<br />
• Site walkover – a site walkover was undertaken to qualitatively assess existing conditions for<br />
pedestrians, cyclists and public transport users.<br />
8.32. The proposed highway assessment methodology follows established practice in testing the<br />
capacity of the local signalised junctions through the use of LINSIG, a recognised junction<br />
modelling software package.<br />
8.33. A number of scenarios have been tested to provide a robust understanding of the effect of the<br />
Development on the operation of individual junctions. They include the following:<br />
• 2015 Base year: Existing Traffic + Background Growth;<br />
• 2015 Opening year: Existing Traffic + Background Growth + Proposed Development.<br />
8.34. Both scenarios have been modelled for the weekday AM peak (08:00 to 09:00), PM peak (17:00 to<br />
18:00) and Saturday peak (12:00 to 13:00) periods.<br />

Access\ES Chapter 8 Transportation Access _JD_BW_003_JD - Final.docx
8.35. In order to project background traffic flows to a forecast year, TEMPRO adjusted National Traffic<br />
model (NTM) 2009 growth values were used to factor the traffic count data to the 2015 opening<br />
year.<br />
8.36. The Development traffic projections were derived from reference to comparable sites in the<br />
industry recognised Trip Rate Information Computer System (TRICS) database. They were<br />
adjusted to take account of the following:<br />
• the traffic generation that could be associated with the existing Site land uses;<br />
• linked trips (multi-purpose trips to / from the Site that involve visits to other local attractions);<br />
• diverted trips (trips already on the network but not the road(s) from which Site access is taken<br />
that would divert from an existing route to access the Site);<br />
• transferred trips (trips already on the network, accessing similar existing Sites nearby, that<br />
would potentially transfer destination to the proposed Development Site); and<br />
• pass-by trips (trips already on the network directly adjacent to the point(s) of access to the Site,<br />
which would turn into the Site).<br />
8.37. The forecasted development traffic was assigned and distributed across the network in accordance<br />
with a two tiered approach. This assigns new and transferred trips in accordance with two-way<br />
flows on key strategic links and locally diverted trips, on the basis of demand for nearby City centre<br />
car parks and through movements on junctions immediately adjacent to the Site.<br />
8.38. The resulting traffic flows provided a basis for testing the operational capacities of the individual<br />
network junctions under each of the assessment scenarios. Operational effectiveness was<br />
determined according to the Practical Reserve Capacity (PRC), which provides an indication of<br />
how much spare capacity there is across the network, and the Degree of Saturation (DoS), which<br />
provides a measure of the efficiency of the network operation. A 90% DoS is generally considered<br />
to represent the practical limit.<br />
8.39. Full details of the trip generation and distribution methodologies are provided in Chapter 6 of the<br />
TA. Appendix 8.1 (<strong>Volume</strong> 3b).<br />
Significance Criteria<br />
8.40. The following level of significance was afforded to differing DoS values:<br />
• Below 0.90 / 90%: Negligible;<br />
• Between 0.90 / 90% - 1.00 / 100%: Minor or moderate adverse;<br />
• Over 1.00 / 100%: Substantial adverse.<br />
8.41. Conditions for pedestrians, cyclists and public transport users were assessed on a qualitative basis<br />
in accordance with the following significance criteria:<br />
• Substantial adverse;<br />
• Moderate adverse;<br />
• Minor adverse;<br />
• Negligible;<br />
• Minor beneficial;<br />
• Moderate beneficial; and<br />
• Substantial beneficial.<br />

Baseline Conditions<br />
8.42. The traffic flows derived for the 2015 base scenario provide an understanding of the operational<br />
capacity at individual junctions prior to the addition of traffic associated with the Development. The<br />
results shown in Table 8.1 summarise the findings.<br />

8.43. It is evident that the network operates well below the 90% practical limit, with the northern Usk Way<br />
arm of the Usk Way / Granville Street junction the busiest at 84% during the weekday AM peak.<br />
Across all of the peak periods the DoS is generally below 70% on each of the junction arms, with<br />
relatively modest levels of queuing that would not interfere with the operation of other nearby<br />
junctions<br />
8.44. The analysis of road accident data identified that there have been a total of 32 accidents within the<br />
study area, with 27 being recorded as slight, 3 as serious and 2 fatalities. Over a third of the<br />
accidents occurred prior to 2008, therefore pre-dating the road improvements implemented on<br />
Kingsway.<br />
Friars Walk, Newport<br />
Chapter 8: Transportation and Access - Page 7<br />

8.45. One of the fatalities, which occurred in 2007, resulted from a pedestrians being struck by a<br />
southbound vehicle when crossing Kingsway alongside the Site frontage. The other fatality<br />
occurred further to the south on Usk Way, and involved a pedestrian falling into the road and being<br />
struck by a passing northbound vehicle.<br />
8.46. A serious accident took place on Kingsway near to the Newport Centre when a pedestrian crossed<br />
the road and collided with a southbound vehicle. The other two serious accidents were at the Old<br />
Green Interchange and involved a vehicle losing control when exiting onto Town Bridge and a<br />
pedestrian being stuck when crossing the Town Bridge.<br />
8.47. The majority of the slight accidents are clustered around Old Green and have primarily been<br />
caused by rear shunts on the approaches to the roundabout. There is also a cluster of five slight<br />
accidents at the Usk Way / Granville Road junction, which were mostly the cause of collisions<br />
between turning vehicles.<br />
8.48. An assessment of the accessibility of the Site highlighted the following:<br />
• the Site is served by an extensive network of pedestrian routes, incorporating a designed<br />
pedestrian zone;<br />
• there are important pedestrian desire lines across the Site, which include the linkage between<br />
the Newport City footbridge and Llanarth Street, and access routes to the Bus Station;<br />
• the Site lies close to National Cycle Route 47 running alongside the River Usk;<br />
• the inclusion of the Bus Station ensures that there is access to a wide range of local, regional<br />
and national bus services;<br />
• the Site lies within a convenient walking distance of Newport railway station; and<br />
• the Site is immediately adjacent to the A4042 Kingsway / Usk Way corridor, which forms a main<br />
route of approach into central Newport and provides linkages to the M4 motorway.<br />
Potential Effects<br />
Demolition and Construction<br />
8.49. It is anticipated that the majority of the vehicular activity would occur outside the highway peak<br />
periods and would be reduced by the earthworks utilising Site-won material, rather than requiring<br />
deliveries by road.<br />
8.50. Heavy Goods Vehicles (HGV) associated with the proposed demolition and construction processes<br />
would be unlikely to present any capacity problems on the road network owing to the minimal trips<br />
per hour made by such vehicles. Accordingly, the effect on local communities and other road users<br />
is anticipated to result in a negligible effect.<br />
Completed Development<br />
8.51. The TA primarily focusses on the effects of the additional Development traffic on the operation of<br />
the highway network. The 2015 opening year traffic flows provide an understanding of the<br />
operational capacity at individual junctions with Development traffic added. The results shown in<br />
Table 8.2 summarise the findings.<br />

8.52. The results show how the AM peak situation is virtually unchanged from the base scenario, with the<br />
DoS peaking at 85% on the northern Usk Way arm of the Usk Way / Granville Street junction.<br />
8.53. In the PM peak there are some modest changes in queuing on the southern arms of the two Usk<br />
Way junctions. The DoS peaks at 87% at the Emlyn Street junction and, at both junctions, queues<br />
of up to 14 Passenger Car Units (PCU) would not compromise operational conditions.<br />
8.54. The Saturday peak exhibits the most widespread changes. In the case of the Usk Way junctions,<br />
these result in queuing that is comparable with or lower than the AM or PM peaks. The higher<br />
levels of demand associated with the Development result in the U-turn manoeuvre on Kingsway<br />

eaching a DoS of 87%. This is within the practical limit and the projected mean maximum queue<br />
of 15 PCUs can be accommodated within the existing stacking lane.<br />
8.55. It can therefore be concluded that the additional and redistributed traffic associated with the<br />
proposed Development can be satisfactorily accommodated on the highway network, thereby<br />
resulting in a negligible effect on road conditions.<br />
8.56. The proposals are intended to encourage pedestrian activity by creating attractive new spaces for<br />
movement and social interaction. They incorporate a comprehensive upgrading of John Frost<br />
Square and the creation of a new adjoining public space in ‘Usk Plaza’, which is situated between<br />
the cinema complex and retail area. One of the main advantages with this arrangement is how it<br />
provides an enhanced linkage between Llanarth Street and the Newport City footbridge, which<br />
forms an important local desire line.<br />
8.57. Pedestrians would be able to walk through the new retail area along a covered multi-level<br />
pedestrianised corridor. This has been aligned with Austin Friars to provide legibility with the<br />
existing built up area. The northern frontage of the Site would also achieve a ‘re-opening’ of the<br />
Upper Dock Street corridor between Austin Friars and John Frost Square, by virtue of the removal<br />
of a section of the Winllan building currently occupied by Iceland.<br />
8.58. The proposals collectively form an extension to the existing City Centre pedestrianised zone and<br />
would provide a coherent network of routes that integrate seamlessly with the surrounding areas. It<br />
was concluded that the proposals would have a moderate beneficial effect on pedestrians.<br />
8.59. As in the existing pedestrianised zone, cyclists would be able to walk with their bicycles through<br />
this area. Cycle parking for 70 bicycles would be provided at prominent locations throughout the<br />
Development to afford ease of access. It was concluded that the proposals would have a minor<br />
beneficial effect on cyclists.<br />
8.60. The proposed Development aims to deliver a reconfigured bus station befitting a modern city in<br />
terms of appearance, accessibility and facilities. The Development also aims to achieve a more<br />
efficient use of space by concentrating the bus bays into a smaller area and dedicating a larger<br />
area to the pedestrian concourse. This is intended to provide a more appealing waiting<br />
environment for passengers that would resolve current issues concerning circulation space, and<br />
conflicts between pedestrians waiting in and walking through the Bus Station.<br />
8.61. The concourse would be covered by a canopy that would shelter passengers from inclement<br />
weather. Access from the upper levels of the retail Development would be provided via two lifts<br />
and there would be direct access from the department store. Movement through the Bus Station<br />
between Corn Street and Kingsway would continue to be catered for. It was concluded that the<br />
proposals would have a moderate beneficial effect on public transport users.<br />
8.62. Access to the basement car park would be provided from Kingsway via segregated entrance and<br />
exit barriers. A total of four barriers (two entry; two exit) are proposed to ensure there is sufficient<br />
processing capability to meet demand.<br />
8.63. Owing to the dual carriageway arrangement along Kingsway, entry and exit would only be available<br />
from the northbound side of the carriageway. A tapered reservoir area has been provided to<br />
enable vehicles to pull clear of passing traffic as they slow to approach the entry barriers. This also<br />
ensures that exiting vehicles can accelerate as they join the traffic flow on Kingsway. It was<br />
concluded that the car park access would have a negligible effect on road users as it is consistent<br />
with that previously in operation at the Capitol car park.<br />
8.64. There would be scope for traffic approaching the Site on the southbound side of Kingsway to<br />
perform a U-turn via the adjacent traffic signalled turning. This arrangement currently facilitates<br />

this turning movement in providing access to the existing bus station. The car park access<br />
proposal does not therefore represent a change to permissible turning manoeuvres in this location.<br />
It was concluded that the proposals would have a negligible effect as this utilises the existing<br />
highway layout.<br />
8.65. It is proposed that entry to the bus station would be achieved via a separate access further to the<br />
north on Kingsway. This effectively uses an existing vehicular access that is currently barricaded<br />
and not in use. Arrangements for buses exiting the bus station would effectively remain as they are<br />
at present, with a priority junction onto Corn Street affording access to Skinner Street and the Old<br />
Green Interchange.<br />
8.66. The reconfiguration of the bus station would require some minor modifications to kerb-lines around<br />
the point where Corn Street adjoins Kingsway and Skinner Street. It was concluded that this would<br />
have a negligible effect on conditions for road users.<br />
8.67. Servicing arrangements would be accommodated at the basement level to the west of the car park.<br />
This essentially represents an expansion of the servicing area used by the Kingsway Shopping<br />
Centre. Access arrangements would be identical to those currently employed by Kingsway<br />
Shopping Centre, with vehicles using the service road leading under the existing multi-storey car<br />
park from Emlyn Street.<br />
8.68. A new public car park has been included as the basement level of the Development and would<br />
accommodate a total of 360 spaces. It forms part of a two phase re-configuration of car parking<br />
provision in this part of the city centre, the first phase having already been completed in 2009<br />
through the construction of the 1,050 space Kingsway multi-storey car park. The two car parks<br />
would collectively replace the spaces lost from the redevelopment of the (former) Kingsway and<br />
Capitol car parks.<br />
8.69. The car park would include 19 allocated parking spaces for disabled users in accordance with<br />
current Council guidelines, which require provision equivalent to 4% plus four spaces. It was<br />
concluded that the car parking arrangements would have a minor beneficial effect in replenishing<br />
the available parking stock.<br />
Mitigation<br />
Demolition and Construction<br />
8.70. Notwithstanding the predicted negligible effects during the demolition and construction process, a<br />
Traffic Management Plan would be developed in consultation with Newport City Council. The plan<br />
would address the following:<br />
• traffic signage and signalling necessary for the direction and control of approaches to the Site;<br />
• suitable routes for materials and for the transport of employees to and from the Site. The<br />
emphasis would be on limiting use of the private car;<br />
• details of any operations, which would obstruct public roads in a way that restricts the free<br />
passage of vehicles; and<br />
• timing of operations and procedures would be discussed with the Highway Authorities prior to<br />
the commencement of construction works.<br />

Completed Development<br />
8.71. No mitigation is required on account of the predicted negligible effects of the additional and<br />
redistributed traffic on road conditions.<br />
8.72. No mitigation is required for pedestrians, cyclists and public transport users on the beneficial<br />
effects of the proposals and the negligible effect of changes in traffic flow on other road users.<br />
Residual Effects<br />
Demolition and Construction<br />
8.73. The implementation of the Traffic Management Plan would assist in ensuring that the likely residual<br />
effect would be negligible, as per the potential effect.<br />
Completed Development<br />
8.74. The likely residual effect would remain unchanged.<br />

9. Air Quality<br />
Introduction<br />
9.1. This Chapter assesses the effects of the proposed Development on air quality. In particular, it<br />
considers the effects of potential emissions from demolition and construction activities, as well as<br />
those from road traffic generated by the completed Development.<br />
9.2. This Chapter describes the methods used to assess the effects, the baseline conditions currently<br />
existing at the Site and in the surrounding areas. It then describes the potential direct and indirect<br />
effects of the Development arising from demolition and construction activities and road traffic, and<br />
the mitigation measures required to prevent, reduce or offset the effects and the residual effects.<br />
9.3. This Chapter has been written by Air Quality Consultants Ltd on behalf of Waterman, Energy,<br />
Environment & Design, and is supported by ‘Technical Appendices 9.1 and 9.2’<br />
Legislation and Planning Policy Context<br />
National Air Quality Policy<br />
9.4. The Air Quality Strategy published by the Department for Environment, Food, and Rural Affairs<br />
(Defra) provides the policy framework for air quality management and assessment in the UK. It<br />
provides air quality standards and objectives for key air pollutants, which are designed to protect<br />
human health and the environment 1 . It also sets out how the different sectors: industry, transport<br />
and local government, can contribute to achieving the air quality objectives. Local authorities are<br />
seen to play a particularly important role. The strategy describes the Local Air Quality<br />
Management (LAQM) regime that has been established, whereby every authority has to carry out<br />
regular reviews and assessments of air quality in its area to identify whether the objectives have<br />
been, or will be, achieved at relevant locations, by the applicable date. If this is not the case, the<br />
authority must declare an Air Quality Management Area (AQMA), and prepare an action plan which<br />
identifies appropriate measures that will be introduced in pursuit of the objectives.<br />
Health Criteria<br />
9.5. The Government has established a set of air quality standards and objectives to protect human<br />
health. The ‘standards’ are set as concentrations below which effects are unlikely even in sensitive<br />
population groups, or below which risks to public health would be exceedingly small. They are<br />
based purely upon the scientific and medical evidence of the effects of an individual pollutant. The<br />
‘objectives’ set out the extent to which the Government expects the standards to be achieved by a<br />
certain date. They take account of economic efficiency, practicability, technical feasibility and<br />
timescale. The objectives for use by local authorities are prescribed within the Air Quality<br />
Regulations, 2000, Statutory Instrument 928 2 and the Air Quality (Wales) (Amendment)<br />
Regulations 2002, Statutory Instrument 3043 3 .<br />
9.6. The objectives for nitrogen dioxide and PM10 were to have been achieved by 2005 and 2004<br />
respectively, and continue to apply in all future years thereafter. In addition, the 2007 Air Quality<br />
Strategy introduced an exposure reduction approach for PM2.5, since ‘there is no recognised safe<br />
level for exposure to particulates (PM2.5)’. However, this is to be assessed at the national level, not<br />
the local level.<br />
9.7. The European Union has also set limit values for nitrogen dioxide and PM10. Achievement of these<br />
values is a national obligation rather than a local one 4 . The limit values for nitrogen dioxide are the<br />

same levels as the UK objectives, but applied from 2010 5 . The limit values for PM10 are also the<br />
same level as the UK statutory objectives, but applied from 2005.<br />

National Planning Policy<br />
Planning Policy Wales (2011)<br />
9.9. Land-use planning policy in Wales is established within the policy document Planning Policy Wales<br />
(PPW) 6 and its updates which provide the strategic policy framework for the effective preparation of<br />
local planning authority development plans. PPW is supported by a series of Technical Advice<br />
Notes (TANs) and National Assembly for Wales Circulars. Local planning authorities have to take<br />
PPW, TANs and Circulars into account when developing Development Plans.<br />
9.10. With respect to planning policy guidance, TAN (Technical Advice Note) 18 on transport 7 makes<br />
reference to local air quality and the need for Air Quality Action Plans to be prepared for any Air<br />
Quality Management Areas declared.<br />
Local Planning Policy<br />
Adopted Newport Unitary Development Plan (UDP) 1996 - 2011<br />
9.11. The Adopted Newport Unitary Development Plan 1996 – 2011 (UDP) was formally adopted in May<br />
2006 8 . The UDP is based on three central themes, one of which is <strong>Environmental</strong> Quality.<br />
9.12. Changes to the planning legislation require the Council to replace the UDP with a Local<br />
Development Plan (LDP). This portfolio of planning documents will deliver the spatial development<br />
strategy for Newport City Council from 2011-2026.<br />
9.13. Newport City Council’s LDP is still under development and so the current UDP policies are still in<br />
force until the transition from the UDP to the LDP is complete. There are several polices that cover<br />
air quality within the UDP. These include:<br />
“SP12 Transport proposals will be favourably considered where they:……”<br />
viii) result in other environmental improvements including to air quality and noise reduction.…”<br />
“SP25 Development will not be permitted which would have an unacceptable effect in terms of<br />
risk to health or safety, or which would be unacceptably harmful to or have an unacceptably<br />
adverse effect on communities or the environment by way of atmospheric, water, noise or other<br />
forms of pollution…”<br />
Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.09 Air Quality\Chapter 9 Air Quality_DRAFT_v2.1.docx
“T9 Development proposals for transport operations involving goods vehicles or public service<br />
vehicles or related uses will be permitted where:<br />
iii) the general character of the area and local residential amenities would not be adversely<br />
affected due to excessive noise, traffic generation, road safety concerns, air or light<br />
pollution.…”<br />
“ED3 Proposals for alternative uses of employment land will be assessed against:…<br />
vii) the degree to which the site may be affected by ground, air or noise pollution and the extent<br />
to which alleviation measures may be effective.…”<br />
Assessment Methodology and Significance Criteria<br />
Assessment Methodology<br />
9.14. This air quality assessment has been undertaken using information from a variety of sources and<br />
has included:<br />
• A review of local air quality monitoring data in order to identify baseline conditions in the area;<br />
• Review of the local area to identify potentially sensitive receptor locations that could be affected<br />
by changes in air quality from demolition/construction associated with the development;<br />
• Traffic flow data provided by the project Transport Consultants, ARUP;<br />
• Scaled plans of the proposed Development;<br />
• Application of an atmospheric dispersion model (ADMS-Roads v3) to predict air pollutant<br />
concentrations for the baseline year and future year both with and without the Development in<br />
place, taking into account traffic;<br />
• Comparison of the predicted pollutant concentrations with the UK air quality objectives and<br />
relevant significance criteria;<br />
• A review of construction information, activities and environmental assessment controls likely to<br />
be employed during the demolition and construction phases of the works; and<br />
• Identification of mitigation measures, where appropriate.<br />
9.15. Construction phase dust effects cannot be easily quantified and therefore a more qualitative<br />
approach has been employed to predict potential effects from these works. The emphasis of this<br />
approach is the minimisation of potential dust effects at source through appropriate environmental<br />
controls relating to site management practices.<br />
9.16. Assessing air quality effects from vehicle emissions requires information on anticipated future<br />
vehicle flows, speeds and types on the local road network in both the absence and presence of the<br />
Development. Based on this information, ambient concentrations of nitrogen dioxide (NO2) and<br />
particulate matter (PM10), are predicted at selected receptor locations. In this way, changes in air<br />
quality that result from the Development can then be established and compared to the Air Quality<br />
Strategy objectives.<br />
Sensitive Receptor Locations<br />
9.17. Concentrations of nitrogen dioxide and PM10 have been predicted at a number of locations close to<br />
the proposed Development. Receptors have been identified to represent worst-case exposure<br />
within these locations. When selecting these receptors, particular attention has been paid to<br />
assessing effects close to junctions, where traffic may become congested, and where there is a<br />
Friars Walk, Newport<br />
Chapter 9: Air Quality - Page 3<br />

combined effect of several road links. The receptors have been located on the façades of the<br />
properties closest to the sources.<br />
9.18. Eleven existing residential properties have been identified as receptors for the assessment. These<br />
locations are described in Table 9.2 and shown in Figure 9.1. In addition, concentrations have<br />
been modelled at the diffusion tube monitoring sites located at on Chepstow Road and Caerleon<br />
Road, in order to verify the modelled results (see Technical Appendix 9.1 for verification method).<br />
9.19. Due to the distant proximity of the sensitive receptors to the Development, it has not been deemed<br />
necessary to assess emissions from the bus station in detail. Emissions from buses using the bus<br />
station have been accounted for in the traffic flow data provided by ARUP, and in the background<br />
pollutant concentrations used in the assessment. None of the receptors are close enough to the<br />
bus station to be affected by significant local effects of bus station emissions, and therefore this<br />
source has not been included directly in the dispersion modelling.<br />

Assessment Scenarios<br />
9.20. Predictions of nitrogen dioxide, PM10 and PM2.5 concentrations have been carried out for a base<br />
year (2010), and the proposed year of opening (2015). For 2015, predictions have been made<br />
assuming both that the Development does proceed (With Scheme), and does not proceed (Without<br />
Scheme). A further 2015 sensitivity test has been carried out for nitrogen dioxide that involves<br />
assuming no reduction in emission factors for road traffic from the baseline year. This is to address<br />
the issue recently identified by Defra 9 that road traffic emissions have not been declining as<br />
expected (see later section on uncertainty). Nitrogen dioxide concentrations in 2015 with and<br />
without the scheme are thus presented for two scenarios: ‘With Emissions Reduction’ and ‘Without<br />
Emissions Reduction’.<br />
Modelling Methodology<br />
9.21. Concentrations have been predicted for the baseline and future years using the ADMS-Roads<br />
dispersion model. Details of the model inputs and the model verification are provided in Technical<br />
Appendix 9.1, together with the method used to derive current and future year baseline nitrogen<br />
dioxide concentrations.<br />

Significance Criteria<br />
Demolition and Construction<br />
9.22. The assessment of demolition and construction effects has been based on a review of the sensitive<br />
uses in the area immediately surrounding the Site in relation to their distance and orientation.<br />
9.23. The significance of effects arising from dust generated by demolition and construction activities<br />
associated with the proposed Development has been based on professional judgement, taking into<br />
account the assessment criteria provided in Table 9.3 and Table 9.4.<br />

9.24. There is no official guidance in the UK on how to describe the nature of air quality effects nor to<br />
assess their significance. The approach developed by the Institute of Air Quality Management 10 ,<br />
and incorporated in <strong>Environmental</strong> Protection UK’s guidance document on planning and air<br />
quality 11 , has therefore been used. This involves three distinct stages: the application of<br />
descriptors for magnitude of change; the description of the effect at each sensitive receptor; and<br />
then the assessment of overall significance of the scheme.<br />
9.25. The definition of effect magnitude is solely related to the degree of change in pollutant<br />
concentrations, expressed in microgrammes per cubic metre, but originally determined as a<br />
percentage of the air quality objective. Effect description takes account of the effect magnitude<br />
and of the absolute concentrations and how they relate to the air quality objectives or other relevant<br />
standards. The descriptors for the magnitude of change due to the scheme are set out in Table 9.5<br />
while Table 9.6 sets out the effect descriptors. These tables have been designed to assist with<br />
describing air quality effects at each specific receptor. They apply to the pollutants relevant to this<br />
scheme and the objectives against which they are being assessed.<br />

9.26. The IAQM guidance 10 is that the assessment of significance should be based on professional<br />
judgement, with the overall air quality effect of the scheme described as either, ‘insignificant’,<br />
‘minor’, ‘moderate’ or ‘major’. In drawing these conclusions, the factors set out in Table 9.7 should<br />
be taken into account. A summary of the professional experience of staff contributing to this<br />
assessment is provided in Technical Appendix 9.2.<br />

Baseline Conditions<br />
Local Air Quality Management<br />
9.27. Newport City Council has investigated air quality within its area as part of its responsibilities under<br />
the LAQM regime. The Council has currently declared nine Air Quality Management Areas<br />
(AQMAs) for exceedences of the annual mean nitrogen dioxide objective, one of which is at<br />
Chepstow Road across the River Usk to the east of the Site 12 . The location of the Chepstow Road<br />
AQMA is shown in Figure 9.2.<br />
9.28. In 2008, the Council developed an Air Quality Action Plan (AQAP) which covers seven of the nine<br />
AQMAs 13 . The AQAP covers only seven AQMAs as these were declared at the time of writing.<br />
Two additional AQMAs, including the AQMA at Chepstow Road, were declared in September 2011.<br />
The AQAP sets out a number of measures designed to improve air quality in the AQMAs, which<br />
Newport City Council has been implementing, or assessing the feasibility of implementing, since<br />
2008. Newport City Council propose to incorporate the two new AQMAs (including Chepstow<br />
Road) into their AQAP as soon as possible 12 .<br />
9.29. In terms of PM10, Newport City Council has concluded that there are no exceedences of the<br />
objectives. It is therefore highly unlikely that existing PM10 levels will exceed the objectives within<br />
the study area 12 .<br />
Local Monitoring<br />
9.30. Newport City Council operates two automatic monitoring stations within its area. Neither of these is<br />
in close proximity to the proposed Development. The Council also operates a number of nitrogen<br />
dioxide diffusion tubes, prepared and analysed by Gradko International Ltd (using the 20% TEA in<br />
water method). These include seven deployed within the proposed Caerleon Road/Chepstow<br />
Road AQMA, to the east of the Site. Results for the previous three years are presented in Table<br />
9.8.<br />

9.31. The diffusion tube monitoring results at Caerleon Road and Chepstow Road indicate that the<br />
annual mean objective is being exceeded at a number of locations within the proposed AQMA.<br />
The results show no clear trends over the past 3 years.<br />
9.32. There are no monitors measuring PM10 or PM2.5 in Caerleon Road. Newport City Council currently<br />
monitors PM10 at St Julians School, where no exceedences of the annual mean or 24hr PM10<br />
objectives have been identified since its installation in 2003. Newport City Council does not<br />
currently predict any exceedences of the PM10 objectives in its area.<br />
Background Pollutant Concentrations<br />
9.33. In addition to these locally measured concentrations, estimated background concentrations in the<br />
study area have been obtained from the national maps for 2010 and the opening year 2015 (Table<br />
9.9). The study area covers a number of grid squares, therefore a range is presented. In the case<br />
of nitrogen dioxide, the 2010 backgrounds have been derived from the 2008 calibrated maps<br />
projected forwards to 2010 assuming no reduction in the traffic emissions. This recognises that<br />
emissions for new vehicles have not been declining as expected (see section on Uncertainty from<br />
paragraph 9.52). The background concentrations are all well below the objectives.<br />

9.34. Baseline concentrations of nitrogen dioxide and PM10 have been modelled at each of the existing<br />
receptor locations (Figure 9.1 and Table 9.2). The results, which cover both existing (2010) and<br />
future year (2015) baseline (Without Development), are set out in Table 9.10 and Table 9.11. The<br />
future baseline for nitrogen dioxide covers the two scenarios: with the official reductions in vehicle<br />
emission factors and without these reductions.<br />

a The numbers of days with PM10 concentrations greater than 50 μg/m 3 have been estimated from the relationship with<br />

9.35. Baseline concentrations of nitrogen dioxide are predicted to exceed the annual mean objective at<br />
six receptor locations in 2010. Four of these locations are within the Chepstow Road AQMA, and<br />
the other two (Receptors 10 and 11) are on Emlyn Street. It should be noted that the ADMS-Roads<br />
Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.09 Air Quality\Chapter 9 Air Quality_DRAFT_v2.1.docx
model was verified using monitoring data in the Chepstow Road AQMA and the results for<br />
receptors at Emlyn Street, on the west side of the River Usk, may be exaggerated. This is<br />
discussed further in paragraph 9.52.<br />
Potential Effects<br />
Demolition and Construction<br />
9.36. The Site currently comprises a number of small buildings and the existing Newport bus station,<br />
which would be demolished prior to redevelopment. The greatest potential for construction effects<br />
is likely to be from the initial phase of demolition and site preparation, and from the passage of<br />
vehicles travelling across unpaved ground during periods of dry weather. There is also the<br />
potential for dust emissions during the handling of dusty materials and the cutting of<br />
stone/concrete. Dust may also be tracked out of the Site onto the adjoining road network. Any<br />
effects would be of a localised and temporary nature.<br />
9.37. Based upon the criteria defined in Table 9.3, the construction activities are judged to be ‘Moderate’<br />
in scale. Without mitigation, significant dust-soiling effects may therefore occur within a distance<br />
up to 200m from the source, whilst PM10 effects may extend out to 50m.<br />
9.38. Dust can be tracked out of construction sites onto neighbouring roads. This can then be raised as<br />
airborne dust by passing vehicles. Without mitigation, it is considered that there is a potential for<br />
significant dust to be found along off-site roads up to 400m from the Site entrance, with dust-soiling<br />
effects potentially extending up to 100m and elevated PM10 effects potentially extending up to 25m,<br />
either side of these roads (see Table 9.3 and Table 9.4)<br />
9.39. The areas potentially at risk from dust and PM10 effects are presented in Figure 9.3 and Figure 9.4<br />
respectively.<br />
9.40. There are a substantial number of commercial premises within 200m of the Site boundary,<br />
including the Commercial Street shopping area, offices on Corn Street and Upper Dock Street, and<br />
the Riverfront development to the east of the Site. There are also a number of residential<br />
properties to the west of the Site at Charles Street and the south of the Site at Emlyn Street, which<br />
lie within 200m of the site boundary. These locations may therefore be at risk of dust soiling during<br />
construction.<br />
9.41. A number of the commercial premises, which lie within 50m of the Site boundary, may also be at<br />
risk from PM10 effects during construction.<br />
9.42. Trackout may lead to dust soiling and PM10 effects at commercial premises alongside Kingsway up<br />
to the Old Green Interchange, Queensway and the Clarence Place bridge, and south along<br />
Kingsway and Usk Road.<br />
9.43. There are no areas of sensitive vegetation within 50m of the Site boundary, and any significant<br />
effects can be discounted.<br />
9.44. The overall significance of effects of dust soiling and PM10 from demolition and construction<br />
activities without mitigation is judged to be moderate adverse. These effects would however be<br />
temporary.<br />
9.45. In light of the potential dust soiling and PM10 effects affecting numerous commercial properties in<br />
the vicinity of the proposed Development, mitigation measures must be considered for construction<br />
dust in order to minimise potential effects.<br />

9.46. Air quality effects from plant operating on the Site and construction vehicles entering and leaving<br />
the Site would be likely to be negligible in the context of local background concentrations or<br />
existing adjacent road traffic emissions.<br />
Completed Development<br />
9.47. Potential effects once the Development has been completed would relate to emissions from<br />
additional traffic movements that are generated on the local road network. These have been<br />
assessed using the ADMS-Roads (v3) atmospheric dispersion model, utilising traffic data provided<br />
by ARUP. Details of the modelling methodology, including a summary of the traffic data provided<br />
for the assessment is included in Technical Appendix 9.1.<br />
9.48. Annual mean concentrations of nitrogen dioxide and PM10, as well as days with PM10 >50 µg/m 3 ,<br />
predicted by the modelling, are set out in Table 9.12 and Table 9.13 for both the “Without<br />
Development” and “With Development” scenarios. These tables also describe the effects at each<br />
receptor using the effect descriptors given in Table 9.6. For nitrogen dioxide, results are presented<br />
for two scenarios to reflect current uncertainty in Defra’s future-year vehicle emission factors.<br />
9.49. Assuming no reduction in vehicle emissions between 2010 and 2015, the annual mean nitrogen<br />
dioxide concentrations are predicted to exceed the objective at four locations within the AQMA, and<br />
two locations outside of the AQMA (at Emlyn Street). The air quality effects are predicted to be<br />
minor adverse at all receptor locations.<br />
9.50. Assuming that vehicle emissions reduce between 2010 and 2015 in line with Defra predictions, the<br />
annual mean nitrogen dioxide concentrations are predicted to exceed the objective at two receptor<br />
locations only in 2015. Both of these receptors are within the Chepstow Road AQMA. The air<br />
quality effects are predicted to be minor adverse at four receptor locations, and negligible at the<br />
remaining seven receptors.<br />
9.51. In terms of PM10 (refer to Table 9.13), no exceedences of the objectives are predicted and all of the<br />
effects from the Development related traffic are negligible.<br />

a The numbers of days with PM10 concentrations greater than 50 μg/m 3 have been estimated from the relationship with<br />
the annual mean concentration described in LAQM.TG(09) (Defra, 2009)<br />
Uncertainty in Road Traffic Modelling Predictions<br />
9.52. There are many components that contribute to the uncertainty of modelling predictions. The model<br />
used in this assessment is dependent upon the traffic data that have been input, which will have<br />
inherent uncertainties associated with them. There are then additional uncertainties, as the model<br />
is required to simplify real-world conditions into a series of algorithms. An important stage in the<br />
process is model verification, which involves comparing the model output with measured<br />
concentrations (see Technical Appendix 9.1). Because the model has been verified and adjusted,<br />
there can be reasonable confidence in the prediction of current year (2010) concentrations.<br />
However, confidence will be greatest at receptor locations close to the monitoring sites used for<br />
verification, in the case of this assessment, receptors within the Chepstow Road AQMA. There can<br />
be considerable local variation in roadside pollutant concentrations and therefore the model results<br />
at receptors to the west side of the Usk River, at Emlyn Street, may not be as reliable, as there is<br />
no local monitoring to the west of the Usk against which the model could be verified. As a<br />
precaution, the verification factor calculated for the Chepstow Road AQMA was used to adjust the<br />
model results at Emlyn Street (Receptors 10 and 11).<br />
9.53. Predicting pollutant concentrations in a future year will always be subject to greater uncertainty.<br />
For obvious reasons, the model cannot be verified in the future, and it is necessary to rely on a<br />
series of projections as to what will happen to traffic volumes, background pollutant concentrations,<br />
and vehicle emissions. Recently however, a disparity between the road transport emission<br />
projections and measured annual mean concentrations of nitrogen oxides and nitrogen dioxide has<br />
been identified by Defra 15 . This applies across the UK, although the effect appears to be greatest<br />
in inner London; there is also considerable inter-site variation. Whilst the emission projections
suggest that both annual mean nitrogen oxides and nitrogen dioxide concentrations should have<br />
fallen by around 15-25% over the past 6 to 8 years, at many monitoring sites levels have remained<br />
relatively stable, or have even shown a slight increase.<br />
9.54. The precise reason for this disparity is not known, but is thought to be related to the actual on-road<br />
performance of diesel vehicles when compared to the calculations based on the Euro standards. It<br />
may therefore be expected that nitrogen oxides and nitrogen dioxide concentrations will not fall as<br />
quickly in future years as the current projections indicate. However, at this stage, there is no robust<br />
evidence upon which to carry out any revised predictions.<br />
9.55. The implications for this assessment are that the absolute nitrogen dioxide concentrations<br />
predicted in 2015 may be higher than shown, when based on the official emissions reduction<br />
forecasts. To account for this uncertainty in the projections, a sensitivity test has been conducted<br />
assuming that the future (2015) road traffic emissions per vehicle are unchanged from 2010 values.<br />
The predictions within this sensitivity test are likely to be over-pessimistic, as new vehicles meeting<br />
more stringent standards will be on the road from 2013/14 15 .<br />
Significance of Air Quality Effects Without Mitigation<br />
9.56. The overall air quality effects of the Development relate traffic are judged to be minor adverse.<br />
9.57. This professional judgement is made in accordance with the methodology set out in paragraph 9.26<br />
taking into account the factors set out in Table 9.14, and also taking into account the uncertainty<br />
over future projections of traffic-related nitrogen dioxide concentrations, which may not decline as<br />
rapidly as currently projected (see paragraph 9.53). The latter has been addressed by giving<br />
consideration to both sets of modelled results for nitrogen dioxide; those with and without<br />
reductions in traffic emissions. It is to be expected that concentrations will fall in the range between<br />
the two sets of results.<br />
9.58. More specifically, the judgement that the air quality effects would be minor adverse takes account<br />
of the assessment that annual mean nitrogen dioxide concentrations are predicted to exceed the<br />
objective and experience minor adverse effects at a number of receptor locations, both within and<br />
outside the Chepstow Road AQMA, and that the PM10 effects are all negligible.<br />

adverse.<br />
No new areas of exceedence of the objective are predicted.<br />

concentrations are likely to lie between the two scenarios.<br />
The annual mean nitrogen dioxide objective is exceeded by<br />
a substantial margin at two receptors within the Chepstow<br />
Road AQMA. The annual mean objective is also predicted to<br />
be exceeded at up to four additional receptors by a lesser<br />
margin.<br />

Mitigation Measures<br />
Demolition and Construction<br />
9.59. An <strong>Environmental</strong> Management Plan (EMP) would be implemented during the demolition and<br />
construction works. This would contain a range of environmental management controls, which will<br />
be developed with reference to the Building Research Establishment guidance ‘Controlling<br />
Particles, Vapour and Noise from Construction Sites’ 16 to minimise the release of dust entering the<br />
atmosphere and/or being deposited on nearby receptors. Such measures are routinely and<br />
successfully applied to construction projects throughout the UK, and are proven to reduce<br />
significantly the potential for adverse nuisance dust impacts associated with the various stages of<br />
demolition and construction work.<br />
9.60. Such measures would include:<br />
• Damping down surfaces during extended periods of dry weather;<br />
• Erection of appropriate hoarding and/or fencing to reduce dust dispersion and restrict public<br />
access, and sheeting of buildings, chutes, skips and vehicles removing demolition wastes;<br />
• Appropriate handling and storage of materials;<br />
• Restriction of drop heights onto lorries;<br />
• Use of ‘deconstruction’ demolition techniques, where appropriate;<br />
• Use of a wheel wash, limiting of vehicle speeds to 5 mph, avoidance of unnecessary idling of<br />
engines and routing of Site traffic as far from residential and commercial properties as possible;<br />
• Fitting all equipment (e.g. for cutting, grinding, crushing) with dust control measures such as<br />
water sprays wherever possible;<br />
• Prevention of dust-contaminated run-off water from the Site;<br />
• Use of gas powered generators rather than diesel if possible (these are also quieter) and<br />
ensuring that all plant and vehicles are well maintained so that exhaust emissions do not breach<br />
statutory emission limits; and<br />
• Ensuring that a road sweeper is available to clean mud etc. from hardstanding roads and<br />
footpaths.<br />
Completed Development<br />
9.61. The assessment has demonstrated that the Development would not cause any exceedences of the<br />
air quality objectives in areas where they are not already currently exceeded. However, the<br />
Development may lead to minor adverse effects on air quality. Mitigation measures to reduce<br />
pollutant emissions from road traffic are principally being delivered in the longer term by the<br />
introduction of more stringent emissions standards, largely via European legislation, and through<br />
implementation of measures contained within Newport City Council’s Air Quality Action Plan 13 ,<br />
which is due to be updated to include the new Chepstow Road AQMA.<br />
9.62. In addition to these measures, a Travel Plan would be implemented to encourage greener modes<br />
of transport and a reduction in private vehicle use. The Transport Assessment completed to<br />
support the planning application for the Site includes a Framework Travel Plan which would form<br />
the basis of a formal Travel Plan should the Development gain approval. The Framework Travel<br />
Plan contains the following outline measures to reduce traffic impacts of the Development:<br />

• Events/promotions;<br />
• Bicycle user group/walk buddies;<br />
• Cycle parking/storage/changing facilities.<br />
Public Transport:<br />
• Service/bus stop improvements;<br />
• Ticketing discounts;<br />
• Timetable displays/promotion.<br />
Private Vehicle Travel;<br />
• Car sharing database;<br />
• Preferential parking allocations;<br />
• Parking for powered two-wheelers.<br />

• Launch event;<br />
• Newsletters/website/notice board.<br />
Operational Efficiencies:<br />
• Pool/fleet cars;<br />
• Video conferencing facilities;<br />
• Co-ordination of deliveries.<br />
9.63. The reduction in vehicle movements to and from the Development associated with effective<br />
implementation of the Travel Plan would lead to a reduction in vehicle emissions which in turn<br />
would lower the air quality effects associated with the Development.<br />
Residual Effects<br />
Demolition and Construction<br />
9.64. The implementation of an EMP for the Site would result in a significant reduction in the potential<br />
effects of dust soiling and PM10 during construction. With mitigation measures in use, the risk of<br />
dust soiling effects is reduced to within 50m of the dust generating activity and risks of PM10 effects<br />
are confined to within 30m of the dust generating activities.<br />
9.65. There remain a number of properties which exist within 50m of the Site boundary where dust<br />
soiling effects may occur during demolition and construction, even with mitigation measures in<br />
place. These properties are principally at the rear of the Site on Upper Dock Street. Austin Friars,<br />
Friars Lane and Llanarth Street. Extra precautions should therefore be taken when working close<br />
to the boundary of the Site to minimise the risk of effects at these locations.<br />
9.66. There are also properties, or portions of properties along these streets (in particular the rear of<br />
properties on Commercial Street), which lie within 15m of the Site boundary and which therefore<br />
would potentially be at risk from PM10 effects.<br />
9.67. With mitigation measures in place, dust and PM10 from trackout is not expected to affect any<br />
properties.<br />

Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.09 Air Quality\Chapter 9 Air Quality_DRAFT_v2.1.docx
9.68. The areas potentially at risk from dust and PM10 effects with mitigation in place are presented in<br />
Figure 9.5 and Figure 9.6 respectively.<br />
9.69. Routine environmental management control measures will be applied throughout the demolition<br />
and construction works at the Site (prescribed by the EMP) in order to prevent unacceptable effects<br />
from occurring. It is possible, however, that at worst, some minor, localised and temporary adverse<br />
effects may occur. Air quality effects from plant operating on the Site and construction vehicles<br />
entering and leaving the Site would be likely to be negligible in the context of local background<br />
concentrations or existing adjacent road traffic emissions.<br />
9.70. The overall significance of effects of dust soiling and PM10 from demolition and construction<br />
activities with mitigation measures in place is judged to be minor adverse.<br />
9.71. Any effects would be temporary and relatively short lived, and would only arise during dry weather<br />
with the wind blowing towards a receptor, at a time when dust is being generated and mitigation<br />
measures are not being fully effective. Such conditions would only arise occasionally during the<br />
construction period, further limiting the potential for any effects.<br />
9.72. Air quality effects from plant operating on the Site and construction vehicles entering and leaving<br />
the Site would be likely to be negligible in the context of local background concentrations or<br />
existing adjacent road traffic emissions.<br />
Completed Development<br />
9.73. The assessment of effects associated with the completed Development has concluded that the air<br />
quality effects would be minor adverse. In light of this, mitigation measures to reduce the air<br />
quality effects of the scheme have been identified through three routes:<br />
• Introduction of more stringent emissions standards for road vehicles (Euro VI vehicles expected<br />
in 2013/2014);<br />
• Implementation of measures outlined in Newport City Council’s Air Quality Action Plan; and<br />
• Introduction of a Travel Plan for the proposed Development.<br />
9.74. It is not possible to quantify the benefit that any of these measures would have, but they would all<br />
lead to reductions in roadside pollutant concentrations, locally (Travel Plan), regionally (Newport<br />
CC AQAP) and nationally (Euro VI).<br />
9.75. Taking all of the mitigation measures listed in paragraphs 9.61 and 9.62 into consideration,<br />
including Travel Plan measures, reductions in vehicle emissions, and implementation of Newport<br />
City Council AQAP measures, the air quality of effects of the Development in 2015 are likely to be<br />
less significant than those outlined in paragraph 9.56, but overall, should still be described as<br />
minor adverse.<br />
Summary and Conclusion<br />
9.76. A summary of the potential and residual air quality effects during both the demolition and<br />
construction phase and once the Development is complete, is presented in Table 9.15.<br />

11. Ground Conditions and Contamination<br />
Introduction<br />
11.1. This Chapter, which was prepared by Waterman Energy, Environment & Design Ltd, presents an<br />
assessment of the likely significant impacts of the Development with respect to ground conditions<br />
and contamination at the Site. It provides an overview of relevant legislation and policy, together<br />
with a description of the methodology used for the assessment. This is followed by a description of<br />
baseline conditions and the potential direct and indirect impacts of the Development. Where<br />
necessary, mitigation measures required to prevent, reduce or offset any adverse impacts are<br />
described.<br />
11.2. The following reports have been used in the preparation of this chapter and are included in<br />
Appendices 11.1, 11.2 and 11.3 of the ES:<br />
• Geo-<strong>Environmental</strong> Investigation, Friars Walk, Newport;<br />
• Preliminary <strong>Environmental</strong> Risk Assessment, Friars Walk, Newport;<br />
• Draft Preliminary Remediation Strategy, Friars Walk, Newport.<br />
Legislation and Planning Policy Context<br />
Legislation<br />
11.3. Land contamination is regulated under several regimes, including environmental protection,<br />
environmental permitting, waste management, planning and development control, and health and<br />
safety legislation.<br />
<strong>Environmental</strong> Protection Act: Part IIA 1990 and Contaminated Land (Wales) Regulations, 2006<br />
11.4. UK legislation on contaminated land is principally contained in Part IIA of the <strong>Environmental</strong><br />
Protection Act (EPA) 1990 1 , which came into force in April 2000 through enaction of Section 57 of<br />
the Environment Act 1995 2 . Part IIA is implemented by the Contaminated Land (Wales)<br />
Regulations 2006 3 and associated statutory guidance (National Assembly for Wales Guidance on<br />
Remediation of Contaminated Land) 4 . These documents describe the risk assessment<br />
methodology that should be adopted in assessing whether a site is contaminated or suitable for<br />
use. Within the legislation, contaminated land is defined as:<br />
“...any land which appears to the local authority in whose area it is situated to be in such a<br />
condition, by reason of substances in, on or under the land, that:<br />
(i) significant harm is being caused or there is a significant possibility of such harm being caused;<br />
or<br />
(ii) pollution of controlled waters is being, or is likely to be, caused.”<br />
11.5. For actual harm to occur, a significant pollutant linkage must be demonstrated using a site-specific<br />
source-pathway-receptor conceptual model. The presence of all three elements must be<br />
established to accord with the definition of contaminated land. The elements of the conceptual<br />
model are as follows:<br />
(i) source – the key pollutant hazards associated with the site;<br />
(ii) receptor – the key targets at risk from the hazards identified e.g. people, environmental assets,<br />
surface water or groundwater; and<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 1
(iii) pathway – the means by which the contaminant can reach and impact the receptor.<br />
Water Resources Act 1991 (Amendment) (England and Wales), 2009<br />
11.6. The Water Resources Act, 2009 5 protects the quality of groundwater and surface water, collectively<br />
defined as ‘controlled waters’.<br />
11.7. The Act is of specific relevance to soil contamination in those cases where the nature, extent and<br />
mobility of contamination present a risk of pollution of controlled waters. In such cases, the<br />
landowner is committing an offence if the pollution of controlled waters is not prevented once the<br />
Site has been identified as being a source of contamination.<br />
11.8. Under Section 161 of the Water Resources Act, the Environment Agency can serve a Works Order<br />
on a person or persons who cause or knowingly permit pollution of controlled waters.<br />
The <strong>Environmental</strong> Protection (Duty of Care) Regulations, 1991 (as amended)<br />
11.9. The <strong>Environmental</strong> Protection Regulations, 1991 6 relate to the requirements on waste producers to<br />
prevent the escape of waste, environmental pollution or harm to human health during the transfer,<br />
treatment or disposal of waste.<br />
Building Regulations, 2000<br />
11.10. The Building Regulations 2000 7 and specifically Approved Document C, Site Preparation and<br />
Resistance to Contaminants and Moisture outlines an approach for the assessment of<br />
contamination and preparation of sites prior to development.<br />
National Planning Policy<br />
11.11. Planning Policy Wales 2011 8 draws attention to the contaminated land regime contained within<br />
Part IIA, stating that local planning authorities should take into account the nature, scale and extent<br />
of contamination which may pose risks to health and the local environment. If investigations have<br />
found significant contamination to be present, local authorities should ensure that development<br />
does not take place without appropriate remediation.<br />
Local Planning Policy<br />
Adopted Newport Unitary Development Plan (UDP) 1996 - 2011<br />
11.12. Policies SP1 (Sustainability), and SP17 (Urban Regeneration) of the Newport Unitary Development<br />
Plan (UDP) 9 encourage the redevelopment of brownfield sites. Policy U13 deals specifically with<br />
contaminated land and builds on the national policy. If a site is suspected to be contaminated then<br />
a comprehensive site assessment will be required to define the nature and extent of contamination<br />
present. Development will not be permitted unless measures are taken in order that:<br />
• The occupiers of the development, together with adjacent land users, are not exposed to<br />
unacceptable risks;<br />
• The structural integrity of any proposed or existing building on or adjoining the site is not<br />
threatened; and<br />
• The contamination of any watercourse, water body or aquifer does not occur.<br />
11.13. The quality and quantity of surface water and groundwater resources, including related nature<br />
conservation interests, are protected through Policy U5 Water Supply; development will not be<br />
permitted which has an unacceptable impact on these resources.<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 2
11.14. Newport City Council is in the process of creating a Local Development Plan (LDP) which will guide<br />
planning in Newport to 2026. Once adopted, this document will replace the existing UDP detailed<br />
above.<br />
Assessment Methodology and Significance Criteria<br />
Assessment Methodology<br />
11.15. A detailed desk study has been completed for the Site, which includes a site-specific conceptual<br />
model, defining the potential contamination sources, pathways and receptors and key potential<br />
pollutant linkages. The study has been undertaken in accordance with current contaminated land<br />
assessment best practice, including the DEFRA contaminated land report series and has included<br />
consultations with Newport City Council and the Environment Agency together with a review of<br />
previous site investigation information relating to work previously undertaken on Site. The<br />
assessment has also followed the contaminated land guidance produced by Newport City Council.<br />
Significance Criteria<br />
11.16. There is no specific methodology or guidance for the assessment of impacts on ground conditions<br />
and contamination for the purposes of EIA. Significance criteria were therefore developed based on<br />
professional judgement and relevant experience. The criteria are based on the potential magnitude<br />
and duration of the impact, the sensitivity of the receiving receptor and the likelihood of the impact<br />
occurring. An explanation of the significance criteria used in this Chapter is provided in Table 11.1.<br />
Table 11.1: Significance Criteria for Ground Conditions and Contamination Assessment<br />
Significance Criteria Description<br />
Adverse Impact of Substantial Significance<br />
Acute or severe chronic impacts on human health<br />
and/or animal/ plant populations predicted. Impact<br />
on a potable groundwater or surface water resource<br />
of regional importance e.g. Principal Aquifer, public<br />
water reservoir or inner protection zone of a public<br />
supply borehole.<br />
Adverse Impact of Moderate Significance<br />
Proven (or likely significant) pollutant linkages with<br />
human health and/or animal/plant populations, with<br />
harm from long-term exposure. Impact on a potable<br />
groundwater or surface water resource at a local<br />
level e.g. impact on an outer groundwater source<br />
protection zone.<br />

Risks to human, animal or plant health are reduced<br />
to acceptable levels. Local scale improvement to<br />
the quality of groundwater or surface water<br />
resources used for commercial or industrial<br />
abstraction.<br />
Beneficial Impact of Moderate Significance<br />
Significant local improvement to the quality of<br />
potable groundwater or surface water resources.<br />

11.17. A detailed description of the Site and surrounding land uses is provided in Chapter 3: Site<br />
Description and Setting.<br />
11.18. Groundcover across the Site generally comprises areas of hardstanding and building footprints;<br />
there is very little permeable groundcover. The bus station is surfaced with concrete, roads are<br />
surfaced with tarmacadam, pavements and other external public areas are surfaced with a<br />
combination of brick blocks, paving slabs and tarmac. Hardstanding is predominantly in good<br />
condition.<br />
11.19. The topography of the Site generally slopes from east to west. The bus station area is located at a<br />
lower level, with John Frost Square forming a flat ‘terrace’ within the Site, below Commercial Street<br />
further to the west. Upper Dock Street slopes up from Corn Street towards John Frost Square.<br />
Existing local ground levels range from approximately 9.0m AOD in the riverside area to the east of<br />
the Site, to 14.3m AOD at Commercial Street to the west, although there are pockets of land within<br />
the Site at levels below 9.0m AOD.<br />
Surrounding Land Uses<br />
11.20. The Site is located in a predominately commercial area of Newport, with a variety of retail, office<br />
and leisure premises located to the north, south, east and west. Several residential properties are<br />
located above commercial premises to the north and west of the Site.<br />
Published Geology<br />
11.21. The geology beneath the site, summarised in Table 11.2 below, has been established from the<br />
British Geological Survey 1: 50,000 scale geological map of Newport, Sheet 249, solid and drift<br />
edition and from previous site investigations detailed in the desk study report. No geological faults<br />
cross or are located in proximity to the Site.<br />

11.22. No obvious signs of contamination were noted during site visits for the desk study and EIA,<br />
however minor localised hydrocarbon staining was noted on the bus station hardstanding and<br />
within the multi-storey car park adjacent to John Frost Square. During the previous site<br />
investigations, no obvious signs of visual or olfactory contamination were recorded in the<br />
exploratory hole logs.<br />
Hydrogeology<br />
11.23. Given the hardstanding groundcover across the Site current infiltration rates are considered likely<br />
to be low.<br />
11.24. According to the Environment Agency groundwater vulnerability map, Sheet 36, Mid Glamorgan,<br />
the Sandstone underlying the site is classified as a Secondary (A) Aquifer of variable permeability.<br />
The aquifer status indicates the aquifer may contain significant amounts of water that are important<br />
for local supplies and for base flows to local rivers.<br />
11.25. Some perched groundwater may be present within the Made Ground. It is considered likely that<br />
locally groundwater flow will follow the local topography and dip of the geology i.e. flow in an<br />
easterly or south easterly direction towards the Usk. Groundwater is likely to be in hydraulic<br />
continuity with the river and may be subject to some tidal variations in levels.<br />
11.26. The Environment Agency’s indicative groundwater abstraction map does not identify any<br />
groundwater abstractions within 1km of the site, and the site is not located within a Groundwater<br />
Source Protection Zone.

These are rock layers or drift deposits with low<br />
permeability that have negligible significance for<br />
water supply or river base flow.<br />
These are permeable layers capable of supporting<br />
water supplies at a local rather than strategic<br />
scale, and in some cases forming an important<br />
source of base flow to rivers. These are generally<br />
aquifers formerly classified as minor aquifers.<br />
11.27. The Site is located in the lower catchment of the River Usk, and within the upper part of the Severn<br />
Estuary - the river is tidal in the Newport area. The Site is located, at its closest point,<br />
approximately 50m to the west of the Usk, which is designated a Site of Special Scientific Interest<br />
and a Special Area of Conservation, and is therefore a sensitive receptor.<br />
11.28. Town Pill is a culverted watercourse located approximately 10m to the north of the Site, which<br />
flows in an easterly direction into the River Usk. The Environment Agency does not keep any<br />
records on river water quality of this watercourse or the Usk in the area of the Site. However, water<br />
quality and sediment loads within the Usk are important due to its ecological status.<br />
11.29. The foul and surface water drainage network currently comprises a variety of separate and<br />
combined gravity systems across the Site. These historically discharged directly to the river via<br />
tidal flaps, but now discharge into a combined trunk sewer of large capacity, located beneath<br />
Kingsway / Usk Way. The combined flows are transferred to the Nash Treatment Works some<br />
distance to the south of the Site. There have been some recorded instances of flooding in the area<br />
due to the volumes of surface water in the sewer system.<br />
Historical Land Uses<br />
11.30. Available Ordnance Survey maps show that by 1883, the majority of the Site had been developed,<br />
with terraced housing across the southern half of the Site and across the northern boundary.<br />
Railway lines ran along the eastern site boundary in the approximate location of Kingsway /Usk<br />
Way. Sidings extended into the northern section of the Site supplying a timber yard (later labelled<br />
as the Austin Friars Saw Mills). A corporation yard was also located in the central area of the Site<br />
at this time (although was redeveloped by 1902). A number of wharfs are shown on the riverside,<br />
to the east of the railway, and iron foundries are located in proximity to both the north and south of<br />
the Site.<br />
11.31. Light industry rapidly developed across the northern half of the Site. By 1902 the housing in the<br />
northern area of the Site had been replaced with industrial units, and a large electricity works was<br />
located to the north of Llanarth Street. This was later to become an electricity board depot. The<br />
Emlyn Ironworks had also been developed adjacent to the southern site boundary.<br />
11.32. Two corporation yards were opened in the central area of the Site between 1937 and 1955.<br />
Kingsway had been constructed adjacent to the railway lines by 1937, with a large car park over<br />
the site of the Saw Mills. The bus station was initially developed within the car park area, but was<br />
subsequently remodelled and significantly expanded to its current layout through the 1970’s.<br />
Expansion of the bus station and construction of the Capitol Car Park required the clearance of the
corporation yards and the electricity board depot. John Frost Square (including retail premises)<br />
was developed by the early 1980’s.<br />
11.33. Outside the site boundary, development of the riverside continued through the 20 th Century, with a<br />
petroleum storage depot located to the east of the Site between the 1950s and 1970s. This area<br />
was then redeveloped as a sand and gravel yard.<br />

11.34. An interpretative geo-environmental report prepared by Waterman (Appendix 11.2) has been<br />
reviewed as part of this assessment.<br />
11.35. This report provided a preliminary assessment of the geotechnical and environmental conditions<br />
likely to be encountered beneath the site and was based on the findings of two phases of intrusive<br />
works, undertaken between February and August 2007.<br />
11.36. The scope of works undertaken across both phases of investigation comprised:<br />
17No cable percussion boreholes to a maximum depth of 6.90m below ground level;<br />
Rotary follow on in 12No boreholes, to depths of between 15m and 30m below ground level;
Groundwater and ground gas monitoring on six occasions;<br />
Geotechnical and environmental laboratory analysis; and<br />
Preparation of an interpretative report.<br />
11.37. The investigation undertaken was preliminary in nature because the site remains occupied by<br />
buildings and infrastructure and it has been acknowledged that further, post demolition<br />
investigation will be required at a later date.<br />
11.38. The ground conditions across the site were found to comprise made ground, present to depths of<br />
up to 4.2m below ground level, underlain by a thin layer of granular and cohesive deposits,<br />
considered to represent completely weathered bedrock or estuarine and marine soils. These were<br />
further underlain by Marl, relating to completely weathered bedrock. Weathered to intact rock,<br />
comprising sandstone, siltstone and mudstone was encountered at depths of between 1.0m and<br />
6.0m below ground level.<br />
11.39. A total of 55No samples of soil were subject to environmental analysis for a wide range of<br />
determinands. Comparison of the results of this against current Waterman Generic Assessment<br />
Criteria for human health (commercial/industrial land use) has indicated that only one determinand<br />
(Benzo(a)pyrene) was elevated in one location of the site. It was noted, however, that<br />
concentrations of Total Petroleum Hydrocarbons (TPH) of up to 2,500mg/kg were recorded in<br />
various locations. There is no assessment criterion for total TPH and at the time of the<br />
investigation, only very limited speciated TPH testing was undertaken. It is therefore possible that<br />
TPH may be present at concentrations potentially harmful to human health.<br />
11.40. Leachate testing did not record any elevated concentrations of contaminants when compared<br />
against the <strong>Environmental</strong> Quality Standards (EQS) or UK Drinking Water Standards, although<br />
elevated concentrations of copper, TPH and Benzo(a)pyrene were encountered within groundwater<br />
samples tested, indicating a potential risk to controlled waters.<br />
11.41. Ground gas monitoring recorded a maximum concentration of carbon dioxide of 3%v/v and<br />
maximum methane concentration of 0.8% v/v, with a peak flow of 4.3l/hour recorded. Using the<br />
guidance in CIRIA report C665 10 , this was calculated to represent Characteristic Situation CS2,<br />
requiring the use of low level passive gas protection measures within structures.<br />
11.42. The laboratory test results were also compared against the Water Regulatory Advisory Service<br />
threshold concentrations of the selection of water supply pipe materials at potentially contaminated<br />
sites. Elevated concentrations of metals, TPH and polycyclic aromatic hydrocarbons (PAH)<br />
indicated that protection measures for water supply pipes would likely be required as part of any<br />
future development.<br />
11.43. The report also included an assessment of the hazardous properties of the deposits present on<br />
site, to assess likely disposal options. This assessment indicated that, as a result of elevated TPH<br />
concentrations the soils on site may be classified as being hazardous. Waste Acceptance Criteria<br />
(WAC) testing indicated that the soils may be suitable for disposal as stable non-reactive<br />
hazardous waste within a non-hazardous landfill.<br />
Current Potential Pollution Linkages<br />
Sources<br />
11.44. Although the site walkover identified no obvious signs of contamination, there is a slight potential<br />
for Polychlorinated Biphenyls (PCBs) to have been contained in the sub-station transformers, and<br />
for spills and leakages of fuels and oils from the bus station and car parks. There was no evidence<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 9
of chemical or fuel storage containers on-site during site visits for the EIA and desk study and,<br />
apart from waste bins, there was no evidence of bulk storage of waste. Historical sources of<br />
contamination within the Site include the electricity works, the corporation yards and timber yard.<br />
11.45. In relation to potential off-site sources of contamination, no current sources are considered to exist.<br />
There are no operational landfills within 250m of the Site; those that were previously operational<br />
were authorised to accept hardcore and rubble only and therefore are considered unlikely to<br />
present a risk in relation to ground gas or leachate generation and migration.<br />
11.46. Potential historical off-site sources of contamination primarily included the Petroleum Storage<br />
Depot to the east of the Site, but also the Emlyn Ironworks adjacent to the south of the Site, and a<br />
second ironworks located to the north of Corn Street. These sites have all been subject to some<br />
redevelopment. The ironworks to the north west of the Site was redeveloped as a cinema by 1920<br />
and again in the 1990s for a mix of use. The ironworks to the south was redeveloped first for<br />
warehouses and then as the Newport Leisure Centre. The petroleum storage depot was<br />
redeveloped as a sand and gravel yard.<br />
11.47. The site investigation undertaken in 2007 indicated that, within the areas of the Site investigated,<br />
only limited elevated concentrations of potential contaminants were encountered within the made<br />
ground beneath the site. Groundwater testing, did, however, record elevated concentrations of<br />
metals, Benzo(a)pyrene and Total Petroleum Hydrocarbons (TPH).<br />
Receptors and Exposure Pathways<br />
11.48. In relation to controlled waters, the River Usk and groundwater within the sandstone aquifer are the<br />
primary receptors. Given the surface water drainage connections that exist between the Site and<br />
the river there is a direct potential pollutant linkage. should a pollution incident occur. The<br />
sandstone comprises a Secondary (A) aquifer, but the Site is not located in a groundwater<br />
protection zone and the alluvial and Marl deposits overlying the sandstone are likely to act as an<br />
aquiclude, providing the aquifer with some degree of protection. Groundwater is likely to be in<br />
hydraulic continuity with the river therefore a second linkage exists between the Site and the<br />
watercourse.<br />
Human Health<br />
11.49. The principal human health receptors are considered to be:<br />
• Construction and maintenance workers;<br />
• Current users of the site and visitors; and<br />
• Users and visitors to adjacent retail areas and local residents.<br />
11.50. There are four key pathways by which humans can be exposed to any potential contaminants, as<br />
defined in the CLR guidance:<br />
• Ingestion of soils or dust;<br />
• Dermal contact with soils or dust;<br />
• Outdoor or indoor inhalation of dust and/or vapours; and<br />
• Consumption of home grown vegetables, with soils attached.<br />
11.51. Since no gardens currently exist within the Site the latter pathway can be discounted. The<br />
extensive hardstanding groundcover reduces risks to the current users of the Site and surrounding<br />
area from ingestion or dermal contact. Concentrations of TPH of up to 2,500mg/kg have been<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 10
ecorded at various locations across the Site and the potential for vapour generation associated<br />
with these cannot be discounted.<br />
11.52. No significant sources of ground gas have been identified on or in the vicinity of the Site and<br />
therefore risks to human health from this source are considered to be low.<br />
Structures and Services<br />
11.53. The existing buildings may be or come into direct contact with potentially contaminated soils. No<br />
evidence of damage or degradation of existing building materials due to contact with the soils was<br />
noted during the site walkover.<br />
11.54. Laboratory testing undertaken to date has indicated that various potentially deleterious<br />
contaminants are present at concentrations that may prove harmful to plastic water supply pipes.<br />
The nature of the water supply pipes on site is unknown and as such, a potential pollutant linkage<br />
has been identified.<br />
11.55. In relation to risks to adjoining properties, the hydraulic gradient across the Site is considered likely<br />
to be to the east / south-east towards the River Usk and therefore lateral migration of any mobile<br />
contamination will be away from the main retail core of the city beneath the highways. Given the<br />
low potential for significant contamination sources on-site a significant pollutant linkage is<br />
considered unlikely to exist.<br />
Soft Landscaping<br />
11.56. The presence of potentially phytotoxic contaminants, including hydrocarbons, has been highlighted<br />
in the ground investigation undertaken to date. It is noted, however, that the trees currently present<br />
on-site appear to be healthy.<br />
Potential Effects<br />
11.57. Both the direct and indirect impacts of the Development have been considered for the following<br />
phases:<br />
• Short to medium term (construction and demolition works); and<br />
• Long term (completed development).<br />
11.58. Both the direct and indirect impacts of the proposed Development have been considered for the<br />
demolition and construction phases and for the operation of the completed Development.<br />
Demolition and Construction<br />
11.59. The detailed scope of construction works for the Development is yet to be finalised. A qualitative<br />
assessment of the potential impacts of the Development during the demolition and construction<br />
phases has therefore been completed, based on reasonable worst case assumptions, with<br />
individual impacts discussed in turn below.<br />
Construction Workers and the General Public<br />
11.60. The demolition and construction works have the potential to mobilise contaminated soils to air, with<br />
the subsequent potential impacts to construction workers and nearby sensitive receptors such as<br />
the public using the nearby commercial and residential properties. The potential for exposure would<br />
be greatest for demolition and construction workers, who may come into contact with contaminated<br />
soils, contaminated groundwater and ground gas during demolition, construction and earthworks,<br />
or may be exposed to contamination through inhalation of fugitive dust and/or vapours. Given the<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 11
low levels of contamination identified on Site, such impacts in the absence of mitigation are<br />
considered to be, at worst temporary, local impacts of minor adverse significance.<br />
Soils, Surface Water and Groundwater<br />
11.61. The existing hardstanding would be removed as part of the excavation works, thereby creating the<br />
potential for rainwater infiltration and potential mobilisation of contamination to underlying<br />
secondary aquifers and increasing the potential for contaminants to migrate off-Site. The impact of<br />
removing hardstanding on soil and groundwater would be, at worst, temporary, local and of minor<br />
adverse significance.<br />
11.62. Potentially polluting substances and activities would be introduced to Site during construction.<br />
These include concrete pouring, the release of suspended sediments to surface waters, storage of<br />
fuels and chemicals within Site compounds and spills and leaks of fuels and oils from construction<br />
vehicles. In the absence of any mitigation, the risk of contamination of soil and groundwater<br />
occurring is considered to be, at worst, a temporary, local impact of minor adverse significance.<br />
11.63. The foundations of the proposed Development would be finalised during detailed design. However<br />
the development would require piled foundations and in the absence of effective mitigation, this<br />
could give rise to the formation of preferential pathways for the movements of contaminants from<br />
the surface to the underlying groundwater during the piling process. This would result in a<br />
temporary, local impact of minor to moderate adverse significance.<br />
Ground Gas<br />
11.64. Construction workers may come into contact with ground gas/hydrocarbon vapour within confined<br />
spaces where a build-up may have occurred. Whilst such exposure can be easily mitigated, without<br />
mitigation potential impacts to construction workers are considered to be, at worst, temporary,<br />
Site-wide and of moderate adverse significance.<br />
11.65. The majority of the potential impacts described above will, however, be reduced or avoided through<br />
the adoption of good design and site management practices, as discussed within the mitigation<br />
measures section of this Chapter.<br />
Completed Development<br />
11.66. A qualitative assessment of potential impacts of the operational development on ground conditions<br />
and water resources has been completed, based on reasonable worst case assumptions. Potential<br />
impacts are as follows:<br />
Future Site Users and General Public<br />
11.67. The majority of the Site would be covered with buildings and hardstanding. These would act as a<br />
barrier between future users of the Site and any residual contaminants present in the soils and<br />
groundwater. Any proposed soft landscaping within the Site could potentially allow future Site<br />
users to come into contact with underlying contamination, creating a pollutant linkage. In the<br />
absence of any mitigation measures, potential impacts are considered to be, at worst, permanent,<br />
Site-wide and of minor adverse significance.<br />
Soils, Surface Water and Groundwater<br />
11.68. The construction of the new Development would require the excavation of soil in order to create the<br />
building foundations. The total volume of excavated soil would be confirmed at the detailed design<br />
stage. The risk of residual contamination beneath the Site due to historic land uses currently<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 12
cannot be ruled out. The built elements of the proposed Development would, however, largely<br />
comprise hardstanding ground cover which would ensure that the quantity of rainwater infiltration<br />
through the potentially contaminated soils remains small. Therefore, the potential for leaching of<br />
contaminants would not increase from the current situation and the potential impact on the<br />
underlying aquifers is therefore considered to be of negligible significance.<br />
11.69. In the absence of any mitigation measures, it is not possible to completely discount the possibility<br />
of spillages occurring associated with the storage of chemicals on-Site and from spills of fuels in<br />
areas of car parking and the bus station. However, limited amounts of chemicals are likely to be<br />
stored on Site and the presence of hardstanding across much of the Site is likely to minimise the<br />
potential for contaminant migration from above ground storage areas towards the underlying soils<br />
and groundwater. The potential impact of the operation of the proposed development is therefore<br />
considered to range from negligible to, at worst, permanent, local, minor adverse significance.<br />
Ground Gas<br />
11.70. Ground gas and hydrocarbon vapour can ingress into confined spaces and can affect the<br />
respiratory system of any persons in these confined spaces for a prolonged period of time (i.e. a<br />
few hours or more) ultimately causing asphyxiation if ventilation is inadequate. In poorly ventilated<br />
buildings or rooms, explosions from the accumulation of flammable gases and vapour are also a<br />
potential hazard. While no potentially significant sources of ground gas have been identified at the<br />
Site, there is a risk that hydrocarbon vapour is being generated. The presence of this would be<br />
determined during the post-demolition Site investigation and the results of monitoring would be<br />
used to inform an appropriate mitigation strategy to prevent the ingress of ground gas/vapour into<br />
the on-Site buildings as necessary. In the absence of mitigation, however, this would be at worst, a<br />
permanent, Site-wide impact of moderate adverse significance.<br />
Buried Structures and Services<br />
11.71. The site investigation work undertaken to date has indicated the presence of potentially degrading<br />
contaminants in the superficial deposits across the Site. These may have the potential to damage<br />
future buried services and structures. Potential impacts are therefore considered to be<br />
permanent, Site-wide and of moderate adverse significance.<br />
Mitigation Measures and Residual Impacts<br />
Pre-Demolition and Construction<br />
11.72. The ground investigations undertaken to date have identified several potential pollutant linkages,<br />
particularly relating to controlled waters. Furthermore, given that a large proportion of the site<br />
remains developed and in use, large areas of land remain uninvestigated. As such, further site<br />
investigation is considered necessary post-demolition. The investigation would include:<br />
• Intrusive works in the areas of the Site yet to be developed;<br />
• Further investigation of the groundwater regime at the site, including detailed quantitative risk<br />
assessment (DQRA) to fully assess the risk from elevated concentrations of metals and<br />
hydrocarbons within the groundwater to the River Usk;<br />
• Further assessment of the ground gas and vapour regime beneath the Site; and<br />
• Geotechnical testing to provide information on the nature of ground conditions, principally for<br />
foundation design.<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 13
11.73. The ground investigation design will be submitted and agreed with Newport City Council and the<br />
Environment Agency Wales, prior to the works. The investigation will allow completion of a<br />
detailed risk assessment, assessing risks both to human health and controlled waters (groundwater<br />
and surface water, in particular the River Usk). The conceptual model produced in the Preliminary<br />
<strong>Environmental</strong> Risk Assessment can then be refined and the preliminary remediation strategy<br />
revised, if required, to ensure that the Site is suitable for use in accordance with the requirements<br />
of Part IIA of the <strong>Environmental</strong> Protection Act.<br />
11.74. A foundation risk assessment will be completed for the Development. The class of concrete<br />
required for the foundations will be selected using the ground investigation data and comparison to<br />
thresholds in BRE Special Digest 1. Based on the results of the monitoring undertaken to date, it is<br />
anticipated that the Site would be classified as Characteristic Situation 2, requiring the use of low<br />
level gas protection measures.<br />
11.75. In order to meet the requirements of the Building Regulations Part C, gas monitoring data from the<br />
ground investigation will be used to categorise the Site, in accordance with current standard best<br />
practice guidance. It will then be determined whether gas protection measures are required for the<br />
development.<br />
11.76. All material excavated would be subject to soil testing and hazardous property assessment in line<br />
with current legislative requirements. In addition, Waste Acceptance Criteria (WAC) tests would be<br />
carried out to obtain an indication of likely waste classification and to investigate opportunities for<br />
reuse.<br />
Demolition and Construction<br />
Construction Workers and the General Public<br />
11.77. During demolition and construction, risks to the public would be minimised by restricting their<br />
access to construction zones and by sensitive working methods, including appropriate dust control<br />
and material stockpile placement. An <strong>Environmental</strong> management Plan (EMP) would be<br />
implemented during the demolition and construction works as a means of identifying and managing<br />
these potential impacts. The EMP would cover issues such as the dampening down of stockpiles<br />
to minimise mobilisation of potentially contaminated dust.<br />
11.78. As discussed above, construction workers are at greatest risk from exposure to contaminated soil<br />
and dust. Any potential exposure to contaminants during the demolition and construction phases<br />
would, however, be minimised through the adoption of standard health and safety procedures and<br />
working methods for construction staff. This would be likely to include the provision of Personal<br />
Protective Equipment (PPE), washing facilities, designated eating areas and careful control of<br />
excavation works to minimise dust generation, and would be enforced through the adopted EMP.<br />
11.79. The above measures would be carried out in accordance with the Health and Safety Executive<br />
(HSE) publication ‘Protection of Workers and the General Public During the Development of<br />
Contaminated Land’ 11 and CIRIA report 143 ‘A Guide for Safe Working on Contaminated Sites’ 12 .<br />
Soils, Surface Water and Groundwater<br />
11.80. In order to minimise the area of permeable groundcover across the Site at any one time, existing<br />
areas of hardstanding would only be removed when necessary. In addition, stockpiles would be<br />
carefully placed, and Visqueen sheeting used where necessary to minimise the risk of<br />
contaminated run-off to groundwater or surface water.<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 14
11.81. The EMP would require fuels and potentially polluting and hazardous materials (such as solvents<br />
and oils) to be stored on areas of hardstanding within appropriately designed bunds, in accordance<br />
with Environment Agency Wales Pollution Prevention Guidelines 13 . The EMP would also include<br />
general pollution prevention guidelines for the demolition and construction works, again based on<br />
EA Wales guidance, and would require spoil containing leachable contaminants to be identified and<br />
suitably contained by bunding or other containment measures. This would minimise the potential<br />
for the release of contaminated run-off to groundwater, drainage systems and soils.<br />
11.82. The implementation of design and control measures prescribed in the foundation works risk<br />
assessment would ensure a reduction of risk to groundwater contamination to an acceptable level<br />
during piling works.<br />
11.83. The results of the site investigations would be used to determine the precise scope of any<br />
remediation of contaminated soils prior to, or during the construction works. The implementation of<br />
the remediation design would make the Site suitable for use and would determine design measures<br />
for buildings, foundations, underground structures and utilities.<br />
11.84. Waste would be transported, treated and disposed of in accordance with the <strong>Environmental</strong><br />
Protection (Duty of Care) Regulations.<br />
Ground Gas<br />
11.85. During the construction phase, ground gases and vapours would be expected to vent through the<br />
excavations undertaken for the foundations for the proposed structures. Safe procedures for entry<br />
into excavations and confined spaces would be developed in line with the HSE and CIRIA<br />
guidance discussed above.<br />
Completed Development<br />
Site Users and General Public<br />
11.86. The proposed Development would be largely covered in buildings and hardstanding, which would<br />
act as a barrier between future Site users and any residual contaminants present in the soils and<br />
groundwater. Any soft landscaping is likely to comprise planted beds. Remedial measures for<br />
these, such as the use of imported clean material would be implemented to break any pollutant<br />
linkage between identified contaminants and gardening personnel/the general public and protect<br />
the health of the plants.<br />
Soils, Surface Water and Groundwater<br />
11.87. Oil-water separators would be installed as part of the surface water drainage system, particularly<br />
within areas of car parking and the bus station, to minimize the potential for oils to enter surface<br />
water bodies or migrate into underlying aquifers.<br />
11.88. Any fuels or chemicals kept above ground on-site would be stored on areas of hardstanding away<br />
from open drains, where spillages can be contained. Storage areas outside buildings would be<br />
provided with an impermeable bund/secondary containment system, which would be capable of<br />
holding at least 110% or the volume of the largest tank, or 25% of the total volume to be stored,<br />
whichever is the greater.<br />
Buried Structures and Services<br />
11.89. The results of the intrusive investigations would be used to determine the precise mitigation<br />
measures required to protect buried services and structures from any potentially degrading<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 15
contaminants. All buried concrete and water supply pipes would be designed accordingly to<br />
reduce the risk to an acceptable level.<br />
Ground Gas<br />
11.90. The results of the site investigations undertaken to date, together with the proposed postdemolition<br />
investigation would be used to design appropriate gas and vapour protection measures<br />
for the proposed structures.<br />
Residual Effects<br />
Demolition and Construction<br />
Construction Workers and the General Public<br />
11.91. Appropriate working methods, including the adherence to an EMP, would minimise the risks<br />
associated with the introduction of new contamination, mobilisation of existing contamination and<br />
introduction of contamination pathways during construction, resulting in a residual impact of<br />
negligible significance to construction workers and the general public.<br />
Soils, Groundwater and Surface Water<br />
11.92. The appropriately timed removal of the existing hardstanding to reduce the potential for rainfall<br />
infiltration would result in, at worst, temporary, local residual impacts of minor adverse<br />
significance on soils and groundwater.<br />
11.93. An EMP would be implemented and best working practices observed, including for the storage and<br />
handling of fuels and chemicals and use of personal protective equipment. However, the risk of<br />
accidental spillages cannot be completely eliminated and, therefore, the likely residual impact is<br />
considered to be, at worst, a temporary, local impact of minor adverse significance.<br />
11.94. The selection of appropriate piling methodology through the completion of a foundation works risk<br />
assessment, together with the treatment or removal and disposal of any contaminated materials<br />
off-site, would result in a permanent, local residual impact of minor beneficial significance to<br />
soils and groundwater.<br />
Ground Gas<br />
11.95. The development of appropriate safe procedures for entry into excavations and confined spaces,<br />
informed by a ground gas risk assessment, would result in a residual impact of negligible<br />
significance to site workers.<br />
Completed Development<br />
Future Site Users and the General Public<br />
11.96. The use of appropriate mitigation, such as the use of clean cover systems in landscaped areas, if<br />
necessary, would result in a likely residual impact of negligible significance to future Site users<br />
and the general public.<br />
Soil, Surface Water and Groundwater<br />
11.97. With the implementation of appropriate fuel and chemical storage facilities and the use of oil water<br />
interceptors as part of the surface drainage network, the residual impacts of the completed<br />
Friars Walk, Newport<br />
Chapter 11: Ground Conditions and Contamination - Page 16
Development on ground conditions, soil and groundwater contamination are predicted to be of<br />
negligible significance.<br />
Ground Gas<br />
11.98. The inclusion of appropriate gas/vapour protection measures within the completed Development,<br />
where necessary, would result in a residual impact of negligible significance.<br />
Buried Services and Structures<br />
11.99. With the implementation of appropriate mitigation measures based on the intrusive site<br />
investigation results, building foundations and buried services such as water supply pipes would be<br />
appropriately designed and likely residual impacts to buried structures and services would be of<br />
negligible significance.<br />

It is evident e fromm<br />

12 2.1) that King gsway West and Usk Wa ay provide a<br />
reeasonably<br />

generally y excludes extreme e floodds<br />
from the area. a To thee<br />
soouth<br />
of the Site,<br />
the level of Usk Way is lower than<br />
the T200 and a T1000 leevels<br />
and this s could alloww<br />
flooodwater<br />
to eenter<br />
the Sit te during botth<br />

12.43. Similarly<br />
at the<br />

Site the level of Kingsway<br />

is lower tha an the T2000<br />

but highher<br />

potential to overtop the Kingsway annd<br />

12.44. Owwing<br />

nature of o flooding, rraising<br />
groun nd levels to facilitate<br />

wo ould not givee<br />
risse<br />
to adverse<br />
flooding ef ffects. The existing serv vice area to the south off<br />
the Site is at a level off<br />
arround<br />
7.50m AOD, i.e. so ome 1,820mmm<br />
below the e T1000 leve el. Due to thhe<br />
fact that th he proposedd<br />
Seervice<br />
Yard aalso<br />
has to be b at this levvel<br />
as it is co onnected to the existing service road d that servess<br />
the<br />
Kingsway Shopping Centre C at thiss<br />
level, the proposed p Se ervice Yard levels<br />
were set at 7.4 too<br />
7. 6m AOD.<br />
12.45. WWithin<br />
the Sitte<br />
there is an a isolated aarea<br />
where the t existing ground leveels<br />
are below w the T10000<br />
levvel.<br />
The lowwest<br />
level wit thin this smaall<br />
pocket is 9.2m 9 AOD an nd therefore only has the e potential too<br />
bee<br />
marginally affected (i.e e. approx. 1000mm)<br />
by floodwater<br />
ba acking up thrrough<br />
the be elow groundd<br />
drrainage<br />
systeems.<br />
12.46. Thhe<br />
isolated loow<br />
lying area a is protecteed<br />
by the sur rrounding hig gher ground and in this case c there iss<br />
noo<br />
reason whyy<br />
the area ca annot be raissed<br />
to facilitate<br />
developm ment.<br />
12.47. WWith<br />
regard too<br />
the propos sed developmment<br />
levels, EAW would normally recommend<br />
th hat minimumm<br />
flooor<br />
slab leveels<br />
should be e at least as high as the T200 thresh hold level ass<br />
projected 60 6 years intoo<br />
the<br />
future (i.e. 2073), as re ecommendedd<br />
in TAN 15. In this case e, the minimuum<br />
level wou uld be 9.04mm<br />
AOOD.<br />
Howeveer,<br />
any development<br />
propposals<br />
would d need to be compatible with existing g access andd<br />
seervicing<br />
levels.<br />
As such h, it may nott<br />
be practica able to satisf fy the recommmended<br />
thr reshold levell<br />
crriterion<br />
for flooor<br />
slabs in all a cases.<br />
12.48. It is also recommmended<br />
th hat the maximmum<br />
depth of o flooding should s not exxceed<br />
600mm<br />
within thee<br />
Site.<br />
Any devvelopment<br />
pr roposals wouuld<br />
however need to be compatible wwith<br />
existing access andd<br />
seervicing<br />
levells<br />
and as su uch it may noot<br />
be possible<br />
in practica al terms to ssatisfy<br />
the recommendedd<br />
crriteria<br />
in all caases.<br />
12.49. Thhe<br />
depth of flooding in the t proposedd<br />
service ya ard, could reach<br />
1.92m. Although th his does nott<br />
coomply<br />
with thhe<br />
recommendations<br />
of TTAN15,<br />
an exception e ma ay be made where it is necessary n too<br />
tiee<br />
in with adjaacent<br />
levels, in this case the existing off-Site serv vice road, annd<br />
hence the e level of thee<br />
seervice<br />
yard could<br />
not be raised r any higher.<br />
It is proposed p to elevate e the fiinal<br />
floor leve els (FFLs) off<br />
the<br />
plant areaas<br />
within the service yardd<br />
to the T200<br />
tidal level, which wouldd<br />
then comp ply with TANN<br />
155.<br />
The preddictable<br />
nature<br />
of tidal fllood<br />
events would mean n ample timee<br />
to evacuate<br />
persons /<br />
veehicles<br />
from the service yard and as such the inundation<br />
of this t external area I unlik kely to causee<br />
annything<br />

13. Townscape and Visual Effects<br />
Introduction<br />
13.1. This Chapter identifies and evaluates the townscape and visual context of the Site and the<br />
surrounding area and considers the likely significant effects of the Development both during the<br />
construction phase and following completion.<br />
13.2. The Chapter summarises relevant policy and guidance concerning townscape and visual matters,<br />
describes the methodology used to assess the baseline conditions of the Site and its environs, and<br />
identifies and assesses the potential effects as a result of the proposed Development to the<br />
townscape and visual amenity. The Chapter then sets out mitigation that may be required with the<br />
aim of preventing, reducing or offsetting any likely significant negative effects arising from the<br />
Development and assesses the resulting residual effects.<br />
Planning Policy Context<br />
13.3. This section outlines relevant townscape and visual related aspects of national, strategic and local<br />
planning policies in relation to the Site. This section should be read in conjunction with Figure 13.1:<br />
Townscape Planning Policy Context which illustrates the location and extents of policies detailed.<br />
National Planning Policy<br />
Technical Advice Note (TAN) 12: Design (2009)<br />
13.4. TAN 12 i provides overarching guidance for the design of new development and commits the Welsh<br />
Assembly Government to delivery of good design which fosters environmental sustainability,<br />
economic development and social inclusion at every scale throughout Wales. In relation to<br />
townscape issues, an appreciation of the landscape context and character of the environment is<br />
specifically highlighted as being integral to the delivery of good design.<br />
Technical Advice Note (TAN) 4: Retailing and town centres (1996)<br />
13.5. TAN 4 ii addresses retailing and town centres. The guidance stipulates the need for <strong>Environmental</strong><br />
Impact Assessment (EIA) for proposals that are situated in sensitive areas and calls for a number<br />
of considerations to that should be considered in order to create successful and vibrant retail and<br />
town centres.<br />
Planning Policy Wales, 2011 iii<br />
13.6. This document provides strategic guiding principles for planning within Wales. Of pertinence in<br />
townscape and visual matters is the hierarchy of landscape designations from National Parks and<br />
Areas of Outstanding Natural Beauty to non-statutory designations such as Special Landscape<br />
Areas and their role to protect landscapes of value within Wales. The use of Countryside Council<br />
for Wales’ LANDMAP information system is advocated.<br />
13.7. Chapter 6 considers the conservation of the historic environment and notes the important<br />
contribution made by historic assets, including conservation areas and listed buildings, within the<br />
townscape. Chapter 10 addresses retailing and town centres, the principal aims being to create<br />
secure, accessible, vibrant, attractive and successful retail and town centre hubs.<br />

Local Planning Policy<br />
Adopted Newport Unitary Development Plan (UDP) 1996 - 2011 iv<br />
13.8. Until the formal adoption of Newport’s Local Development Plan, which is currently in formulation,<br />
the Newport Unitary Development Plan (UDP) is the main planning policy guidance document for<br />
development within the City. Policies relevant to townscape and visual amenity are summarised<br />
below. Reference should also be made to Figure 13.1 Townscape Planning Policy Context.<br />
13.9. Strategic policies SP1 to SP9 provide overarching principles for development and the environment.<br />
These policies seek to promote sustainable development, encourage high quality design and<br />
protect and enhance both the natural and built environment.<br />
13.10. Policy CE4 relates to soft landscape schemes for new developments and encourages the retention<br />
of existing landscape features, such as ponds, hedges or trees, of value within development<br />
proposals.<br />
13.11. Trees and hedgerows within development sites are protected under Policy CE13, which seeks<br />
replacement planting for those lost as a result of the development.<br />
13.12. Listed buildings and their settings are protected under Policy CA15. The accompanying text notes<br />
that “listed buildings play a significant role in the townscape and architectural heritage of the area”<br />
and the Council attaches the utmost importance to their preservation.<br />
13.13. Development neighbouring conservation areas is considered in Policy CE20. Development will<br />
only be permitted provided that it preserves or enhances the architectural or historical character or<br />
appearance of the conservation area, including their setting.<br />
13.14. Urban regeneration within Newport is encouraged within Policy CE30, particularly those which<br />
result in “the protection and enhancement of the built and natural environment, townscape qualities<br />
and the condition and appearance of buildings, especially in the Usk riverfront corridor…”<br />
13.15. Policy CE30 is supported by Policy CE32 which advocates the protection and enhancement of<br />
important routeways and transport corridors, including the A4042 Usk Way, by undertaking<br />
environmental improvement measures.<br />
13.16. Policy CE33 allows the allocation of ‘environmental spaces’ within the City. These are areas<br />
identified for their importance in terms of their visual, wildlife or recreational and amenity qualities.<br />
Development that adversely affects the designation’s attributes will not be permitted.<br />
13.17. Policy CE38 champions good design and notes the importance of development proposals to<br />
respond sensitively to both the Site and its context in terms of character, scale, form, materials and<br />
detailing.<br />
13.18. The creation of long distance cycle routes is facilitated under Policy T14 although the protection of<br />
and recreational experience from is not considered.<br />
Supplementary Planning Guidance<br />
Newport 2020 Unlimited Vision, April 2004 v<br />
13.19. This document sets out a vision for the future management and regeneration of Newport. Included<br />
in the vision is a masterplan for regeneration and design guidance principles to inform development<br />
proposals.<br />

Newport Public Realm Strategy, July 2006 vi<br />
13.20. The Newport Public Realm Strategy sets out strategic guidance for the creation and management<br />
of the public realm within Newport. A number of recommendations are proposed with the aim of<br />
creating “an attractive, safe and clean pedestrian environment”.<br />
Usk River Strategy, July 2009 vii<br />
13.21. The Usk River Strategy provides guidelines and principles for the management of the river Usk<br />
corridor. The document recommends the protection and enhancement of the visual amenity and<br />
character of the river corridor and encourages development that contributes positively to the<br />
existing character and uniqueness of the river edge.<br />
Draft Supplementary Planning Guidance – Newport City Centre Masterplan<br />
(2004) viii<br />
13.22. Although not formally adopted, Newport City Council’s draft SPG provides an indication of<br />
emerging policy for the area. Of note in relation to townscape and visual issues is the production of<br />
a draft masterplan for Newport City Centre which sets out an indicative vision for new development<br />
in the City Centre.<br />
Statutory Designations<br />
Tree Preservation Orders<br />
13.23. There are no Tree Preservation Orders (TPOs) within the Site.<br />
Conservation Areas<br />
13.24. The western ends of Friar’s Walk, Austin Friar’s and Llanarth Street are located within the Town<br />
Centre Conservation Area. In the absence of full planning permission, notification needs to be<br />
made to the Council for any works to trees within the Conservation Area. The location of all<br />
conservation areas within the vicinity, namely the Town Centre Conservation Area, Lower Dock<br />
Street Conservation Area and St Woolos Conservation Area further south is shown within Figure<br />
13.1.<br />
Registered Parks and Gardens<br />
13.25. There are no registered historic parks and gardens within the Site. The closest is the Grade II<br />
listed Bellevue Park, approximately 800m to the southwest.<br />
Listed Buildings<br />
13.26. There are no listed buildings within the Site. Details of the nearest to the Site are provided in<br />
Chapter 14: Archaeology and Built Heritage.<br />
Assessment Methodology and Significance Criteria<br />
Assessment Methodology<br />
13.27. The assessment methodology for the townscape and visual assessment is based on the following<br />
guidance, with assessment principles within the documents applying to both townscape and visual<br />
contexts.<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 3
‘Guidelines for Landscape and Visual Impact Assessment’, Landscape Institute (LI) and Institute<br />
of <strong>Environmental</strong> Management and Assessment (IEMA) 2002 (Second Edition) ix ; and<br />
‘Townscape Character Assessment’ x , the Countryside Agency and Scottish Natural Heritage<br />
(SNH) 2002.<br />
13.28. The townscape and visual assessment consists of two separate, but inter-linked issues as follows:<br />
Townscape Effects: The effects of the development on the physical and cultural characteristics<br />
of the Site and its surroundings and on the townscape character of the study area; and<br />
Visual Effects: The effects of the development on views from visual receptors and on the<br />
amenity value of these views.<br />
13.29. The assessment methodology adopted for townscape and visual matters comprises a combination<br />
of desktop and field studies including the following:<br />
An overview of statutory plans and other data regarding relevant designations and planning<br />
polices for the area;<br />
An analysis of the Countryside Council for Wales’s LANDMAP data for the Site and its<br />
surrounds;<br />
GIS analysis using Ordnance Survey profile data to calculate the topography of the area and<br />
establish a Zone of Theoretical Visibility (ZTV) (refer to Figure 13.2);<br />
A site visit to inform the assessment of the townscape character of the Site, together with the<br />
sensitivity of the townscape to change. This includes the classification of the townscape into<br />
units of distinct and recognisable character;<br />
Identification of viewpoints and classifications of sensitivity;<br />
Production of fully verified wireline Accurate Visual Representations (AVRs) to inform the<br />
assessment and support this chapter;<br />
Identification and assessment of the potential townscape and visual effects of the Development<br />
and their significance; and<br />
The preparation of mitigation proposals with the aim where possible, of avoiding or reducing<br />
significant adverse townscape or visual effects, determined during the course of the<br />
assessment.<br />
13.30. The visual assessment is based on views from external spaces within the public domain and not<br />
from inside buildings or private spaces. However, assessment of private dwellings is made where<br />
appropriate. Site visits were undertaken in October 2011and November 2011. This time period<br />
represents optimum conditions for visual assessment due to the absence of deciduous vegetation<br />
cover. Photographs were taken from selected viewpoints using a digital camera with a 50mm focal<br />
length lens at eye level (1600mm) from the ground. The camera location and details of each<br />
viewpoint were recorded. Photograph locations were selected and agreed in consultation with<br />
Newport City Council (NCC).<br />
13.31. The townscape and visual assessment has been informed by other studies, including Chapter 14:<br />
Archaeology and Built Heritage and the Arboricultural Report which is included as Technical<br />
Appendix 3.1 should be read in conjunction with the chapter.<br />
Significance Criteria<br />
13.32. The significance of townscape and visual effects are determined by assessing:<br />
The sensitivity of the affected townscape;<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 4
The sensitivity of the visual receptor; and<br />
The magnitude of the potential change that will occur.<br />
13.33. This is illustrated graphically as ‘significance matrices’ for both townscape character and visual<br />
effects, as contained within Figures 13.3 and 13.4.<br />
13.34. The assessment process aims to be objective and quantify effects as far as possible. However, it<br />
is recognised that subjective judgement is appropriate, if it is based upon training and experience,<br />
supported by clear evidence, reasoned argument and informed opinion. Whilst changes to a view<br />
can be factually defined, the evaluation of townscape character and visual effect does require<br />
qualitative judgements to be made. The conclusions of this assessment therefore combine<br />
systematic observation and measurement with informed professional interpretation. Waterman has<br />
obtained the EIA Quality Mark from the Institute of <strong>Environmental</strong> Management and Assessment<br />
(IEMA) and has experience in assessing the visual effects for various development schemes in a<br />
variety of scenarios.<br />
13.35. The assessment of the nature of townscape and visual effects depends on the degree to which the<br />
Development:<br />
Complements, respects and fits into the existing scale, landform and pattern of townscape<br />
context;<br />
Enables enhancement, restoration or retention of the townscape character and visual amenity;<br />
and<br />
Affects strategic and important views in addition to the visual context of receptors.<br />
13.36. Based upon the significance matrices contained within Figures 13.3 and 13.4, the assessment of<br />
potential and residual townscape and visual effects can be described as being:<br />
Very High Beneficial: The Development would fit in extremely well with the scale, landform<br />
and existing pattern of the townscape, and bring substantial enhancements. The development<br />
would create a very significant improvement in views;<br />
High Beneficial: The Development would fit very well with the scale, landform and existing<br />
pattern of the townscape, and bring considerable enhancements. The Development would<br />
create a significant improvement in views;<br />
Moderate Beneficial: The Development would fit well with the scale, landform and existing<br />
pattern of the townscape, and maintain and/or enhance the existing townscape character. The<br />
Development would create a noticeable but improved change in the views;<br />
Minor Beneficial: The Development would complement the scale, landform and pattern of the<br />
townscape, whilst maintaining the existing character. The Development would result in minor<br />
improvements to the views;<br />
Negligible: The Development would cause very limited changes to the townscape and/or<br />
views, but creates no significant effects;<br />
No effect: There will be no perceptible effect as a result of the Development on either the<br />
townscape character or the visual amenity of the built environment;<br />
Minor Adverse: The Development would cause minor permanent and/or temporary loss or<br />
alteration to one or more key elements of the townscape. This includes the introduction of<br />
elements, which may not be uncharacteristic of the existing townscape. The Development<br />
would cause limited visual intrusion;<br />
Moderate Adverse: The Development would cause considerable permanent loss or alteration<br />
to one or more key elements of the townscape, to include the introduction of elements that are<br />
Friars Walk, Newport<br />

prominent but may not be substantially uncharacteristic of the townscape. The Development<br />
would be visually intrusive and would adversely affect upon the townscape;<br />
High Adverse: The Development would cause substantial permanent loss or alteration to one<br />
or more key elements of the townscape, to include the introduction of elements that are<br />
prominent and uncharacteristic of the townscape. The Development would be visually intrusive<br />
and would adversely affect the townscape; and<br />
Very High Adverse: The Development would cause total permanent loss or major alteration to<br />
key elements and features of the townscape, to include the introduction of elements totally<br />
uncharacteristic of the surrounding townscape. The Development would be very visually<br />
intrusive and would disrupt fine and valued views both into and across the area.<br />
Assumptions and Limitations<br />
13.37. No assumptions or limitations have been identified as part of the townscape and visual<br />
assessment.<br />
Baseline Conditions<br />
Site Description and Context<br />
13.38. The Site is approximately 4ha in area and centred on National Grid Reference 831273, 188005. A<br />
detailed description of the existing site can be found in Chapter 3: Site Description.<br />
13.39. The extant townscape of the Site comprises Newport bus station and associated bus bay area,<br />
adjoining multi-storey car park, retail units, John Frost Square and pedestrian routes. Built form<br />
dates from the 1960s and displays many characteristics of modernist architecture synonymous with<br />
the period including clean architectural forms and lines, covered walkways, minimal façade<br />
detailing and a preponderance of concrete and brick. As such, the Site appears somewhat dated,<br />
although does not exhibit the dilapidation and neglect often associated with other city and town<br />
centres of a similar period.<br />
13.40. Amongst the recent mid-20 th century built form of the city centre are a number of Victorian and<br />
Edwardian buildings, notably the Newport Market and the elegant suburbs of St Woolos, visible<br />
manifestations of the wealth generated by the industrial heritage of the city. To the east of the Site,<br />
the regeneration of the riverside has progressed apace with an assortment of futuristic buildings<br />
jostling for attention on the water front.<br />
Topography<br />
13.41. The Site lies at approximately 9m AOD. To the east of the Site, the land falls to the River Usk<br />
which forms a prominent and expansive physical feature within the townscape. To the west the<br />
terrain rises to approximately 109m AOD at the Ridgeway, which affords panoramic views over<br />
Newport to the Severn Estuary and expansive countryside to the west.<br />
Landcover<br />
13.42. The Site is completely surrounded by built form, comprising commercial, retail and residential uses.<br />
To the east, areas of landscape planting associated with the realignment of the Kingsway soften<br />
the highway corridor, whilst a number of mature trees are present within pedestrian areas<br />
neighbouring the Site. The River Usk forms a prominent and attractive natural feature, cutting<br />
through the built form and opening up the townscape.<br />

Townscape Character<br />
National Character – Countryside Council for Wales - LANDMAP<br />
13.43. The Countryside Council for Wales LANDMAP provides a detailed analysis and categorisation of<br />
the landscapes of Wales from a number of landscape aspects. These are:<br />
Geological Landscape: this is the study of the geology, geomorphology and hydrology of the<br />
area;<br />
Landscape Habitats: looks at the distribution of vegetation and habitats and the basis for<br />
landscape ecology;<br />
Visual & Sensory: this aspect identifies those landscape qualities that are perceived through<br />
the senses. It deals with the individual physical attributes of landform and land cover, as well as<br />
their visual patterns of distribution and sensory characteristics, and the relationships between<br />
them in a particular area;<br />
Historic Landscape: focuses on how archaeological and historical sites relate to each other<br />
and to the surrounding landscape;<br />
Cultural Landscape: this considers the relationship that exists between people and places;<br />
how people have given meaning to places, how the landscape has shaped their actions and<br />
their actions have shaped the landscape.<br />
13.44. The LANDMAP aspects are divided into a hierarchical system of established geomorphological<br />
classification based on scale, from Level 1 (general landscape character) to Level 4 (small scale<br />
landform).<br />
Geological Landscape<br />
13.45. CCW’s LANDMAP classifies the Site within the Newport (Pilgwenlly-Crindau) area described as<br />
Man-made/Engineered features and reclaimed / infilled land (unique area code NWPRTGL002) in<br />
terms of geological landscape. The accompanying descriptive text adds:<br />
“Intensively developed area of former coastal flat and flood plain occupying a ''promontory'' of<br />
land between the Usk and Ebbw (now heavily modified as dockyards). Also includes the low<br />
area of central Newport on the west side of the Usk as far north as Crindau. Includes a<br />
bypassed former meander of the Ebbw and the developed lowest part of the Malpas Brook flood<br />
plain, close to its confluence with the Usk. <strong>Main</strong>ly underlain by estuarine deposits (Quaternary:<br />
Holocene).”<br />
13.46. Notable Level 4 components include flood plain and coastal defence works, reclaimed land, urban<br />
and industrial development and engineered topography.<br />
13.47. The value of this area is low (intensively developed with few or no natural features remaining),<br />
whilst its condition is poor in a constant trend. The principal management recommendations are<br />
stated as:<br />
“Although intensively developed at surface, former coastal deposits exist at depth. Recording<br />
such deposits by drill coring prior to development can provide important information not only on<br />
the development of the coastal flats, but also on late to post glacial climate change.”<br />
Landscape Habitat<br />
13.48. The Site is classified as Dry (Relatively) Terrestrial Habitats/Built Up Areas/Industrial as part of the<br />
landscape habitat assessment (unique area code NWPRTLH039). Habitats recorded within this<br />
area include broad leafed woodland, intertidal mud mud/sand, buildings and amenity grassland.<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 7
The descriptive text adds “This is a large industrial area adjacent to the River Usk. There is some<br />
green space in the north of the area which is also common land and which is mainly amenity<br />
grassland. There is an inter-tidal river which may support native species.”<br />
13.49. The value of this area is assessed as low although it is noted the intertidal habitats and areas of<br />
green space within the built form do have the potential to support native species. The condition<br />
and trend of this landscape habitat area has not been assessed. Principal management<br />
recommendations are to enhance the network of green spaces and improve biodiversity within<br />
them.<br />
Visual and Sensory<br />
13.50. The Site is included within Newport West area (unique area reference NWPRTVS056), which<br />
essentially covers the whole of Newport city and suburbs, and is described as Development/Built<br />
Land/Urban at Level 3. The summary description adds:<br />
“West Newport - part of the city on the western side of the Usk running from hills at 109 m AOD<br />
at the Ridgeway to 10m AOD on the flat valley floor and levels. The area includes the Victorian<br />
retail centre of Newport, close to the Usk, with vibrant main street and relatively new mall. The<br />
Portland stone art deco Civic Centre is dominant on a hill overlooking the city and visible from<br />
the station and railway. Stow Hill to the south with the church of St Woolos is the other main<br />
landmark of note. The most affluent houses, detached and semi-detached, lie north of the civic<br />
centre on the higher ground, some with views to the countryside to the north on the Ridgeway.<br />
Victorian development of terraces lie to the south towards the docks. To the west there is<br />
expansion of estates, some council, which form the eastern margins of the built up area and are<br />
visible from the M4 above the Gaer fort. Stow Park and Bellevue Park are important formal<br />
open spaces. The A4042 cuts a strong swathe into the town centre, with traffic dominating this<br />
area.”<br />
13.51. The metadata records underline the preponderance of a diverse range of built form, often found in<br />
a discordant arrangement. Views of the Ridgeway are noted as important whilst views of existing<br />
built form and dual carriageways are noted as detractors. The sensory and visual value of the area<br />
is assessed as low, the accompanying text stating “Despite a few highlights, the urban form has<br />
many detractors and is relatively incoherent so the overall value is low” before adding “Despite high<br />
points of St Woolos/Stow Hill, Civic centre and High street and parks, the city has relatively<br />
incoherent urban form with some urban elements in poor-moderate condition.”<br />
13.52. However both scenic quality and character is considered to be moderate, with the principal<br />
management recommendations being to “improve main road corridors and commercial areas<br />
where possible, improve green network and maximise screening on edges from peripheral roads.”<br />
Historic Landscape<br />
13.53. The historical landscape of the Site is identified as Newport Historic Centre, described as Built<br />
Environment/Settlement/Nucleated Settlement/Planned Settlement - Medieval at Level 4 (unique<br />
area code NWPRTHL023). The historical pattern is identified as Water & Wetland,<br />
Nucleated Settlement Processing/Manufacturing Communications and Military at Level 3 and<br />
Planned Settlement Mediaeval to 20th century, Water Industry, Factory, Distribution and Retail<br />
Services, Canal Harbour/Port/Dock and Medieval Military at Level 4, with regional vernacular<br />
prevalent architecturally.<br />
13.54. The area is considered to be of high value, although in poor condition, the justification text noting:<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 8
“The historic urban core of Newport owes its present appearance and architectural character to<br />
mid to late 19th century development, which has largely obscured evidence of the pre-19th<br />
century topography, with the exception of the castle, cathedral and an early 17th century<br />
merchant's house. The reorganisation of the road system in the 1970s has significantly<br />
detracted from the coherence of the urban landscape along the riverfront.”<br />
13.55. The current historic management of the area is generally considered to be acceptable and the<br />
principal management recommendation is stated as being to “mitigate the impact of new urban<br />
developments on the archaeological record by adhering to current legislation.”<br />
Cultural Landscape<br />
13.56. The Site is included within the City of Newport (unique area reference NWPRTCL025) identified by<br />
Influences/Material expressions/Urban/Other Urban at Level 4. The dominant cultural context is<br />
recorded as Industrial Urban, Infrastructure, Institutions, Customs, Artistic and Media with<br />
particularly significant cultural landscape aspects at Level 4 identified as Sense of Place, Famous<br />
People, Land Holdings, Land Divisions, Religions & Beliefs, Politics, Educational Movements,<br />
Leisure/Recreation, Social Events and Institutions, Art, Literature, Music, Press, TV and Radio.<br />
13.57. The value of the cultural landscape is assessed as outstanding and in good condition with an<br />
improving trend. The existing management is considered to be appropriate with principal<br />
management aim of balancing ambition with the needs of those who live in multiple deprivation<br />
communities.<br />
Local Character<br />
13.58. In order to understand the effects to character of the Site and surrounding area at the detailed<br />
level, Waterman has undertaken an assessment of townscape character at the local level. A<br />
summary of the townscape context is provided from which character areas have been identified<br />
and illustrated within Figure 13.5: Townscape Character Areas, which should be referred to when<br />
reading this section.<br />
Local Character<br />
13.59. The local character of the Site is dominated by modernist architect synonymous with the mid-20 th<br />
Century. The muscular forms of multi-storey car parks and office blocks made of concrete and<br />
brick have imposed themselves on the existing townscape and now occupy the main retail area of<br />
the city centre. Buildings dating from this post-war planning phase include the Bus Station and its<br />
adjoining multi-storey car park, as well as Chartist Tower and Olympia House, which form notable<br />
landmarks within the townscape.<br />
13.60. The older fabric of the town also survives in places, as attested by the designation of the Town<br />
Centre Conservation Area, albeit overshadowed by the bulky forms of post war development.<br />
Notable examples include Newport Market in the French Renaissance, St Woolos County Primary<br />
School, and the frontage of Commercial Street, which provides an attractive continuous<br />
thoroughfare through the main retail centre.<br />
13.61. More recently, the regeneration of the west bank of the River Usk has seen the creation of a<br />
distinct area of contemporary, even futuristic, architecture in the guise of the Riverfront Theatre and<br />
University of Wales Newport campus as well as the newly constructed footbridge.<br />
13.62. Consequently, the townscape of Newport is a diverse range of styles and eras reflective of the<br />
period in which buildings were constructed. The eclectic mix, creates diversity providing an overall<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 9
vibrant, authentic townscape although does not lend itself to coherency or legibility. In order to<br />
assess the effects to the townscape the following townscape areas have been identified.<br />
TCA1: City Centre Retail Core<br />
13.63. TCA1 comprises the Site and other mid-20 th Century development of the city centre. The character<br />
area can be identified by its modernist architecture which include brick and concrete as a building<br />
material, muscular, bulky forms and clean architectural lines with minimal façade detailing. Notable<br />
paragons include Chartist Tower, Olympia House and the multi-storey car parks of the bus station<br />
and Kingsway Centre. This TCA is very much introspective, turning inwards on John Frost Square<br />
and the bus station, and as such does not openly engage with the surrounding townscape.<br />
13.64. Key characteristics of TCA1 include:<br />
Mid-20 th century modernist buildings;<br />
Large bulk and form; and<br />
Preponderance of concrete as a building material.<br />
13.65. As this TCA does not contain any townscape designations it is assessed as being of low (local)<br />
sensitivity.<br />
TCA2: Commercial Street Historic Core<br />
13.66. TCA2 abuts the Site to the west and is centred on the primary shopping high street of Commercial<br />
Street, which forms the main conduit through the city centre. This TCA contains the many<br />
buildings from the Georgian period, identified by their classical architecture and large, white<br />
fenestrations, and in combination with its tree lined streets, retains much of its regency charm.<br />
Consequently, much of TCA2 is designated as the Town Centre Conservation Area, protecting the<br />
integrity of the TCA2’s built form.<br />
13.67. Key characteristics of TCA2 include:<br />
Historic Georgian core of the city identified by classical architecture styles;<br />
<strong>Main</strong> retail high street of the city centre with bustling flow of pedestrians;<br />
Number of listed buildings and tree lined streets.<br />
13.68. As the TCA is designated within the Towns Centre Conservation Area and contains a number of<br />
listed buildings it is assessed as being of high (local) sensitivity.<br />
TCA3: Riverside Regeneration<br />
13.69. TCA3 abuts the Site to the east. It has a distinct character from that of the surrounding built form as<br />
a result of the contemporary buildings that jostle on the waterfront for attention. Flagship buildings,<br />
such as the Riverfront Theatre and Arts Centre and University of Wales Newport campus building<br />
comprise futuristic forms with angular lines and colourful cladding, wood and glass. That is not to<br />
say that this townscape is incoherent, and both buildings, along with the dynamic structure of the<br />
footbridge, combine to create a striking and engaging waterfront scene. Recent landscape planting<br />
around the buildings and the Kingsway has softened the interface between built form and knits the<br />
TCA together although, as a result of the intervening built form of TCA1, the area feels slightly<br />
detached from the main bustling core of the city.<br />
13.70. Key characteristics of TCA3 include:<br />
Striking post modernist architecture creating a diverse and engaging waterfront;<br />
Utilisation of contemporary materials including glass, coloured cladding and wood; and<br />
Recent landscape planting softening built form;<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 10
13.71. Although only of recent origin, the character of TCA3 contains many locally valued townscape<br />
components. It is therefore considered to be of moderate (local) sensitivity.<br />
TCA4: Stow Hill and St Woolos Suburbs<br />
13.72. The residential suburbs to the west of the Site are classified within TCA4. Situated on Stow Hill<br />
overlooking the City, the elegant Georgian townhouses were the preferred residential abodes of the<br />
wealthy of the City. Today the area retains much of its charm and the ordered residential streets,<br />
sprinkled with small parks and squares are in stark contrast to the heavy industry at the mouth of<br />
the River Usk. Highlights of TCA4 include the Norman Grade I listed St Woolos Cathedral and the<br />
prominent Grade II listed Baroque style St Woolos County Primary School.<br />
13.73. Key characteristics of TCA4 include:<br />
Genteel and ordered Georgian residential suburbs;<br />
Elevated location overlooking Newport; and<br />
Patchwork of parks and squares.<br />
13.74. As much of the area is protected under the St Woolos Conservation Area and contains a number of<br />
listed buildings, TCA4 is considered to be of high (local) sensitivity.<br />
TCA5: Eastbank Suburbs<br />
13.75. The low-lying residential suburbs on the eastern bank of the River Usk are classified within TCA5:<br />
Eastbank Suburbs. TCA5 contains a diverse and somewhat eclectic range of land uses, from tall<br />
office blocks such as Clarence House to Newport Athletic Club sports ground and small light<br />
industrial business. However, the preponderant built form is that of two storey residential terraced<br />
housing, largely from the Edwardian period. A large area of vacant land adjacent to the river is<br />
also prominent and likely to be developed in the near future for additional residential housing<br />
although it is fair to say that the area in general is looking somewhat jaded.<br />
13.76. Key characteristics of TCA5 include:<br />
Eclectic and diverse range of land uses;<br />
Edwardian two storey terraces and vacant land predominant; and<br />
Flat topography and adjacent to riverfront although no real connection.<br />
13.77. The sensitivity of TCA5 is considered to be low (local) as it is largely devoid of townscape<br />
designations and is reasonably tolerant of change.<br />
TCA6: Lower Dock Street<br />
13.78. The area to the south of the Site is classified within TCA6: Lower Dock Street. As with TCA5, the<br />
character area contains a diverse range of built form, from Victorian residential terraces (included<br />
within the Lower Dock Street Conservation Area) to more recent supermarket developments.<br />
Much of the historic built form has been eroded by more recent development and an assortment of<br />
newsagents and fast food takeaways. However, the TCA is a vibrant one and emits an energy of<br />
industriousness.<br />
13.79. Key characteristics of TCA6 include:<br />
Diversity of businesses and retail;<br />
Historic built form eroded by recent development; and<br />
A vibrant and diverse community.<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 11
13.80. The sensitivity of TCA6 is considered to be high (local), as a result of the Conservation Area<br />
designation.<br />
13.81. Key townscape character receptors of the locality are considered to be:<br />
The bus station and John Frost Square retail precinct;<br />
The character of the Town Centre Conservation Area; and<br />
The character of the riverside.<br />
Visual Amenity<br />
13.82. The visual amenity of the Site has been assessed from seven representative views of the Site from<br />
the surrounding environment. A description of each view, potential receptors and their sensitivity is<br />
detailed within Table 13.1 whilst Figure 13.6 illustrates the location of the views in relation to the<br />
Site.<br />
13.83. In order to provide context, a brief summary of the visual amenity of the townscape in relation to<br />
the Site is provided below.<br />
13.84. The key physical visual feature of Newport is the River Usk and its surrounding hills, which allow<br />
views over the City to the Severn Estuary and beyond. Although the river is often screened by built<br />
form, it is dominant in close range views of the Site. Striking architectural buildings and sculptural<br />
artworks along the waterfront create diversity and interest within views, drawing the viewer’s<br />
attention. Forming a backdrop to this are the landmark tall and bulky buildings of Chartist Tower,<br />
Olympia House and Clarence House, along with the bus station and Kingsway Centre multi-storey<br />
car park. Older buildings, although often less prominent, also draw the eye and the towers of<br />
Newport Market, The Council offices, spires and cupolas of churches and halls, bridges and the<br />
ruins of the Castle all serve to create interest within views and add to a rich tapestry of visual<br />
experience.<br />

also form notable landmarks within the view. Part of<br />
the Site is visible in the middle ground.<br />
View from Hill Street Car Park looking northeast<br />
toward the Site. The open car park location allows<br />
a brief view over the townscape from the east at<br />
street level. The support beams of the footbridge<br />
over the River Usk and the Kingsway Centre multistorey<br />
car park form notable features to the south of<br />
the view whilst the suburbs of Summerhill and<br />
Shaftsbury can be seen to the centre and north<br />
respectively. The Site is largely screened by<br />
intervening built form.<br />
View from the east bank of the River Usk near Cyril<br />
Street. The post-modern form and façade of the<br />
University of Wales campus building grabs the<br />
attention as do the lance like supports of the<br />
footbridge. Chartist Tower and Clarence House to<br />

view. The Site can be seen in the middle ground, of<br />
which the Newport bus station multi-storey car park<br />
is the most discernible.<br />
View from Christchurch Road in Summerhill looking<br />
southwest toward the Site. The raised topography<br />
allows panoramic views over the city centre<br />
although at street level the majority of views are<br />

beams, Chartist Tower and the tower of Newport<br />
Council Offices all form landmarks within the view.<br />
The Site can be seen in the centre of the view.<br />
View from Upper Dock Street at the junction with<br />
Corn Street looking southeast. The juxtaposition of<br />
architectural styles within Newport City Centre is<br />
apparent in this view, the detailed classical facades<br />
of Georgian era buildings in stark contrast to the<br />
modernist of the mid 20 th century. Part of the Site, in<br />
particular the multi-storey car park, can be seen in<br />
the middle ground.<br />

13.85. Some trees within the Site, notably the mature silver maple on Austin Friars within the Town Centre<br />
Conservation Area, provide an attractive verdancy to the street scene. Other more mature London<br />
Plan and Purple Maple trees adjacent to the Bus Station, although not of outstanding quality in<br />
themselves provide a useful screening function to the Kingsway Road. Reference should be made<br />
to the arboricultural report contained within Technical Appendix 3.1 in relation to the value of trees<br />
on and near the Site.<br />
Potential Effects<br />
Demolition and Construction<br />
13.86. Demolition and construction within the Site would entail the demolition of the bus station, multistorey<br />
car park and retail units within the Site, along with the reconfiguration of John Frost Square.
Reference should be made to Chapter 14: Archaeology and Built Heritage for effects to built<br />
heritage as a result of the demolition phase.<br />
13.87. Demolition and construction within the Site has the potential to affect the townscape and visual<br />
amenity of the Site and its surrounds in a number of ways. Potential disruptive operations include:<br />
Site demolition and clearance;<br />
Site access and haulage routes using the existing road infrastructure;<br />
Fixed construction plant, such as cranes;<br />
Mobile construction plant, such as excavators and lorries;<br />
Disposal of material;<br />
Stockpile and material storage areas;<br />
Erection of welfare facilities and protective hoardings;<br />
Security and safety lighting; and<br />
The presence of partially constructed buildings.<br />
13.88. In townscape and visual terms, all demolition and construction effects identified are considered to<br />
be direct (i.e. as a direct consequence of the Development) and short-term in timescale (i.e. less<br />
than 2 years), lasting for the duration of the demolition and construction process. The significance<br />
of effects has been identified using the methodology detailed above and the matrices contained<br />
with Figures 13.3 and 13.4.<br />
13.89. For both townscape and visual, effects are largely temporary, except for the removal of mature<br />
vegetation which is considered permanent.<br />
Townscape Character<br />
13.90. Owing to the extensive demolition and construction within the Site, the potential effects to the<br />
townscape character of the Site and close vicinity is anticipated to be considerable. The demolition<br />
of existing buildings, movement of heavy plant and materials and restriction of access would cause<br />
severe disruption to the character of the Site and TCA1. Construction within the Site is likely to<br />
interrupt the direct connectivity between City Centre (TCA2) and Riverfront (TCA3), although as<br />
previously noted in the baseline assessment, the Site in its current condition does not encourage<br />
movement between the two at present. The magnitude of change to the character of the Site and<br />
TCA1 is assessed as high and although of low sensitivity, the scale and extent of the works<br />
required by their nature is anticipated to result in direct, short-term effects of minor to moderate<br />
adverse significance before mitigation.<br />
13.91. Fortunately, as this TCA is introspective, being self-contained from the surrounding townscape,<br />
character effects are likely to be limited geographically to the Site and its close environs. The<br />
Kingsway Road forms a distinct physical boundary to the east, buffering the character of TCA3,<br />
whilst the Site backs on to the rear of Commercial Street within TCA2, allowing the frontage of<br />
Commercial Street to function without any substantial effect. The magnitude of change to the<br />
character of TCA2 and TCA3 is therefore assessed to be low at worst resulting in direct, shortterm<br />
effects of negligible to minor adverse significance.<br />
13.92. TCAs 4, 5 and 6 are considered far enough distant from the Site to experience no effects as a<br />
result of demolition and construction within the Site.<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 14
Visual Amenity<br />
13.93. As with townscape character, construction within the Site is likely to be prominent in close range<br />
views from neighbouring environs. Construction activities, although notable, would enliven the Site<br />
acting as a very visible sign of regeneration and renewal of the area.<br />
Local Views (Photoviewpoints 1 and 7)<br />
13.94. The receptors most affected visually would be those along and adjacent to the Kingsway Road to<br />
the east of the Site (Photoviewpoint 1) and Skinners Road to the north (Photoviewpoint 7) where,<br />
as a result of their proximity, construction activities would be prominent in views. However,<br />
although extensive, the scale of construction is similar to that of existing built form and is not<br />
anticipated to detract from existing visual landmarks, such as Chartist Tower or the Riverfront<br />
Theatre. Again, the relative self-containment of the Site should mean that construction is seen<br />
within a distinct area of the city, which should largely prevent the visual composition of remaining<br />
areas of the city centre being affected. It is also of note that these areas are of relatively low<br />
sensitivity, with few private residents and absence of sensitive designations, and the established<br />
fact that visible construction workings is something to be expected within built up city centre areas.<br />
Nonetheless the magnitude of change to receptors of local views is assessed to be medium to high<br />
resulting in direct, short-term effects of minor to moderate adverse significance.<br />
Gateway Views (Photoviewpoints 1 and 3)<br />
13.95. As the height of construction is similar to that of surrounding built form, construction within gateway<br />
views to the city centre from Newport Bridge (Photoviewpoint 3) and the Kingsway (Photoviewpoint<br />
1) is largely anticipated to blend amongst existing built form or be screened by it. Views of other<br />
gateway buildings, such as Newport Castle and the Riverfront Theatre would continue to be<br />
unobstructed. A low magnitude of change is therefore anticipated to gateway views resulting in<br />
direct, short-term effects of minor adverse significance.<br />
Views from the east bank of the River Usk (Photoviewpoints 2, 3 and 5)<br />
13.96. The majority of views of construction from the east bank of the River Usk would be blocked by<br />
intervening built form on the west bank. However, from certain points along the bank, namely<br />
directly opposite the Site, views to the construction within the Site would be possible between<br />
breaks in the built form. In these views, construction activities would be seen amongst the<br />
panorama of the townscape and, although likely to be prominent (Photoviewpoint 2), are not<br />
anticipated to dominate the composition. It is of note that visual effects to these views would be<br />
less that those experienced for the construction of recent buildings on the west bank of the River<br />
Usk in addition to the fact that much of the east bank area is to redeveloped for housing in the near<br />
future. As a result, construction work would not be seen as ‘out of context’ within the area.<br />
Consequently the magnitude of change to receptors on the east bank of the River Usk is assessed<br />
as medium resulting in, at worst, direct, short-term effects of minor adverse significance.<br />
Views from Residential Suburbs to the West (Photoviewpoint 4)<br />
13.97. In views from residential suburbs to the west (Photoviewpoint 4), construction within the Site is<br />
likely to be screened by intervening built form. This is anticipated to be the case for local receptors<br />
within the Town Centre Conservation Area where the built form along Commercial Street would<br />
screen all but narrow views down pedestrian link streets of the Site.<br />
13.98. It is likely that more open views of construction are possible from upper storeys of dwellings set<br />
further up Stow Hill, as opposed to at street level, however, owing to the similar scale of the<br />
Development to surrounding built form, these activities are not anticipated to be overly prominent<br />
within views. As with other townscape locations, the presence of construction activities within<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 15
views of the townscapes should not be unexpected. The magnitude of change to views from this<br />
area is therefore considered to be medium to low resulting in direct, short-term effects of<br />
negligible to minor adverse significance.<br />
Views from Residential Suburbs to the East (Photoviewpoint 6)<br />
13.99. The raised topography of Summershill affords panoramic views over the city centre of Newport.<br />
Within these views construction within the Site is likely to form a notable although not prominent<br />
feature within the view and, as with views from Stow Hill, be more open from upper storeys of<br />
dwellings than at street level. As noted previously, finished building levels would be similar to that<br />
of existing built form and largely blend amongst existing built form spread within the view. The<br />
function of other landmark buildings within the view would continue to operate and the horizon set<br />
by Stow Hill is unlikely to be broken. The magnitude of change is therefore assessed to be low<br />
and, although of very high sensitivity for receptors at this location, result in direct, short-term<br />
effects of negligible significance.<br />
Completed Development<br />
13.100. The completed Development would see a comprehensive change to the built form within the Site<br />
as old, and dated structures are replaced by new and contemporary forms and vernaculars. In<br />
relation to townscape and visual assessment the key changes are considered to be:<br />
The creation of new built form, utilising contemporary materials and vernaculars, replacing that<br />
of old;<br />
The creation of new areas of public space, in particular Usk Plaza;<br />
The improvement of existing public space, in particular John Frost Square;<br />
The creation of a new double height covered arcade (Friars Walk) linking John Frost Square<br />
and Usk Plaza with Upper Dock Street;<br />
The reorganisation of existing routes, including the reopening of the historic alignment of Austin<br />
Friars as a direct link between Commercial Street and Upper Dock Street.<br />
13.101. To inform and support the townscape and visual assessment seven fully verified, wireline<br />
photomontages have been produced (Figures 13.12 – 13.18) which should be referred to when<br />
reading this section.<br />
Townscape Character<br />
13.102. In character terms, the replacement of the unsightly multi-storey car park and retail units with<br />
modern built form and public space would create interest within the street scene and invigorate the<br />
urban environment. The use of contemporary materials and the creation of a covered arcade along<br />
Friar’s Walk would create a high quality townscape experience unique to Newport. The<br />
consolidation of the bus station is anticipated to lessen the visual prominence of standing buses<br />
and reduce the amount of ‘sterile space’ it creates within the Site at present. Connectivity between<br />
the townscape would also be improved, the sweeping curved façade of the Development drawing<br />
people from the riverfront, through Usk Plaza and John Frost Square, to Commercial Street and<br />
beyond (Figure 13.13).<br />
13.103. Taking all of the above into consideration, the magnitude of change to TCA1, which includes the<br />
Site, is assessed to be high resulting in direct, long-term effects of moderate to high beneficial<br />
significance.<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 16
13.104. Beneficial effects to adjoining townscape character areas, namely TCA2: Commercial Street<br />
Historic Core and TCA3: Riverside Regeneration, are also anticipated. As connectivity between<br />
these areas is improved, the townscape would become more legible to the pedestrian and the flow<br />
of movement between the city centre, the Site and the riverside should become more natural and<br />
coherent. Indeed, the overall coherence of TCA1, TCA2 and TCA3 would be improved and the city<br />
centre would work more effectively as a larger entity whilst retaining the distinct characteristics of<br />
each individual quarter. The magnitude of change to TCA2 and TCA3 is assessed as medium<br />
resulting in direct, long-term effects of minor to moderate beneficial significance.<br />
13.105. Other character areas, owing to their distance and separation are unlikely to experience any<br />
significant effects to their character, and therefore effects to TCA4, TCA5 and TCA6 as a result of<br />
the completed Development are anticipated to be negligible.<br />
Visual Amenity<br />
13.106. The completed Development would create attractive and notable new built form within views. This<br />
is not considered to be incongruous or alien given the existing visual context, particularly that of<br />
landmark buildings along the riverfront. Importantly, it is considered that the completed<br />
Development would complement the existing contemporary built form context and, as a result of its<br />
sensitive scale, would not compete with established landmark buildings and structures along the<br />
riverfront (Figures 13.13 and 13.16). Moreover, the roofline of the completed Development is<br />
below that currently set by the multi-storey car park within the Site (Figure 13.3).<br />
Local Views (Photomontages 1 and 7)<br />
13.107. In local views from Upper Dock Street (Figure 13.18) the completed Development would enclose<br />
the street scene although the roofline is similar to that of existing 3 storey built form that lines this<br />
road. The addition of new materials and facades is anticipated to create interest within the street<br />
scene and draw the pedestrian through the townscape, which is considered an improvement on the<br />
unsightly multi-storey car park and vapid retail units at present.<br />
13.108. In views from the Kingsway (Figure 13.12) views of landmark buildings would be retained and the<br />
openness of the view would remain. The completed Development would reflect heights of<br />
surrounding built form and sit well below the level of Chartist House, which would remain the<br />
prominent landmark within the view. The provision of soft landscape along the eastern frontage<br />
would soften built form and create a continuous avenue of planting along the Kingsway as one<br />
travels past the Site. The magnitude of change to local views is assessed as low to high<br />
(depending on proximity) resulting in direct, long-term effects of minor to high beneficial<br />
significance.<br />
Gateway Views (Photomontages 1 and 3)<br />
13.109. As with local views, the completed Development is expected to form a notable feature within<br />
gateway views (Figures 13.12 and 13.14). However, its sensitive scale means that it would not<br />
compete with existing landmark buildings, views of which would remain. The planting along the<br />
eastern frontage would create a boulevard of planting and in combination with existing planting<br />
create an attractive arrival experience to the city centre. The magnitude of change to gateway<br />
views is assessed as medium resulting in direct, long-term effects of minor to moderate<br />
beneficial significance.<br />
Views from the east bank of the River Usk (Photomontages 2, 3 and 5)<br />
13.110. In views from the east bank of the River Usk (Figures 13.13 and 13.16) the completed<br />
Development would appear as a notable feature within views, forming a backdrop to landmark<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 17
uildings on the waterfront. The height of the roofline would be below that set by the Kingsway<br />
Centre and provision of soft landscape planting along the eastern frontage would soften the built<br />
form. The overall coherency of the view is anticipated to be improved. Importantly views to the<br />
Cathedral would remain. The magnitude of change to receptors in these locations is assessed to<br />
be medium resulting in direct, long-term effects of minor to moderate beneficial significance.<br />
Views from Residential Suburbs to the West (Photomontage 4)<br />
13.111. The completed Development would, certainly at street level, be screened from view (Figure 13.15).<br />
It is possible that upper reaches may be visible from upper storeys of buildings in this area<br />
although are not anticipated to be prominent within the views – largely blending amongst the<br />
roofscape of the city centre. As the roofline of the completed Development is below that of existing<br />
built form present on the Site, the panoramic views over the city centre available from this location<br />
would be maintained. The magnitude of change is assessed to be low resulting in negligible to<br />
minor beneficial effects to visual receptors in this area.<br />
Views from Residential Suburbs to the East (Photomontage 6)<br />
13.112. The completed Development is likely to form a notable part of the composition in views from the<br />
east (Figure 13.17), where it is expected to complement the landmark riverside buildings visible<br />
and clearly demarcate the heart of the city centre. Views of the Cathedral would remain and the<br />
horizon formed by the western suburbs would remain unbroken. The magnitude of change to<br />
views from this location is therefore found to be low resulting in direct, long-term negligible to<br />
minor beneficial effects.<br />
Mitigation Measures<br />
Demolition and Construction<br />
13.113. Due to the nature of construction it is inevitable that some adverse effects would occur to the<br />
townscape and visual amenity of the Site and its immediate environs. The significance of these<br />
effects can, however, be limited by implementing the following strategies:<br />
Tactical phasing to minimise disruption to areas that can continue to function as normally as<br />
possible during construction activities;<br />
Adoption of a construction <strong>Environmental</strong> Management Plan (EMP) to ensure good site<br />
management and housekeeping;<br />
Adoption of dust and noise avoidance measures to limit the intrusion of construction activities<br />
on local environs;<br />
Careful siting of construction machinery, materials and welfare facilities to avoid unnecessary<br />
intrusion, particularly in regards to privacy of adjacent areas;<br />
Erection of semi-temporary wooden hoarding around construction areas to clearly delineate<br />
working areas; and<br />
The creation of alternative pedestrian routes around working areas to allow continued<br />
movement between the city centre and Riverfront.<br />
Completed Development<br />
13.114. No adverse effects have been identified to the townscape and visual amenity as a result of the<br />
completed Development. The following should however be given careful consideration to ensure<br />
the full potential of beneficial effects to the townscape and visual amenity are realised.<br />
Friars Walk, Newport<br />
Chapter 13: Townscape and Visual Effects - Page 18
The use of public art and containerised soft landscape planting within public areas and spaces;<br />
The use of high quality and sensitive materials for building facades and the floors, particularly<br />
public areas;<br />
The planting of larger/more mature trees along the eastern frontage of the Development to aid<br />
assimilation and add maturity to the scheme; and<br />
The adoption of a landscape/ecology management plan to ensure the successful maintenance<br />
and contribution of soft landscape planting, including greenroofs, in the future.<br />
Residual Effects<br />
Demolition and Construction<br />
13.115. The successful implementation of the mitigation measures detailed above is likely to reduce<br />
moderate adverse effects identified to the character of TCA1 to minor adverse. Negligible to<br />
minor adverse effects identified to TCA2 and TCA 3 would be reduced to negligible. TCAs 4, 5<br />
and 6 are considered far enough distant from the Site to experience no effects as a result of<br />
demolition and construction within the Site.<br />
13.116. Receptors of local views to minor to moderate adverse significance at worst. However, it should<br />
be appreciated that owing to the extensive nature of the proposals it is inevitable that significant<br />
temporary disruption to close range receptors is unavoidable. Effects to other visual receptors<br />
would be negligible.<br />
Completed Development<br />
13.117. In townscape and visual terms, the completed Development is anticipated to result in direct, longterm<br />
minor to high beneficial effects, the most notable effects being in the proximity of the Site<br />
and its neighbouring environs. Overall the coherency, unity and legibility of the townscape of the<br />
Newport city centre would be greatly improved. The landscape enhancements detailed above<br />
should be implemented to ensure the full potential of these benefits is realised.<br />
13.118. No adverse effects have been concluded for the completed Development.<br />

14. Archaeology and Built Heritage<br />
Introduction<br />
14.1. This Chapter was prepared by Waterman Energy, Environment & Design (Waterman EED). It<br />
considers the direct effects of the proposed Development on known heritage assets<br />
(archaeological remains and built heritage) within the Site and immediately surrounding areas,<br />
including their settings. In particular, it considers the effects of the construction works and of the<br />
completed Development on potential heritage assets beneath the Site.<br />
14.2. This Chapter includes a summary of legislation, policy and guidance, and existing conditions at the<br />
Site. This Chapter makes an assessment of the potential direct effects on heritage assets,<br />
resulting from the construction works and the completed Development, and any mitigation<br />
measures required to prevent, reduce or offset any adverse effects. The resulting residual effects<br />
are also discussed.<br />
14.3. This chapter is supported by Technical Appendix 14.1 and Technical Appendix 14.2 which present<br />
a desk based Archaeological Assessment and Written Scheme of Investigation respectively.<br />
Legislation and Planning Policy Context<br />
Planning Policy<br />
National Planning Policy<br />
Scheduled Monuments and Archaeological Area Act, 1979<br />
14.4. The Scheduled Monuments and Archaeological Area Act 1979 1 does not apply in this case, since<br />
no heritage assets designated as Scheduled Monuments would be affected by the proposed<br />
Development.<br />
Planning (Listed Buildings and Conservation Areas) Act, 1990<br />
14.5. The Planning (Listed Buildings and Conservation Areas) Act 1990 2 requires the Secretary of State<br />
to compile, update and maintain a list of buildings and other structures that are considered to be of<br />
special architectural or historic interest. Those included on the ‘list’ are graded according to their<br />
architectural or historic importance, these being Grades I, II* and II in descending order of<br />
architectural and/or historical importance. Development proposals affecting the character or<br />
appearance of a listed building require Listed Building Consent to first be obtained.<br />
14.6. Within the provisions of the Planning (Listed Buildings and Conservation Areas) Act (1990) local<br />
authorities are entitled to designate areas considered as of special architectural or historic interest<br />
as conservation areas. Any application for planning permission for a development, which, in the<br />
opinion of the local authority, would change the appearance or character of the conservation area<br />
would require Conservation Area Consent.<br />
Welsh National Policy, 2011<br />
14.7. National land use planning policy in Wales is set out in the fourth edition of ‘Planning Policy Wales’<br />
published in February 2011 (PPW4) 3 . This document contains current land use planning policy for<br />
Wales, consolidating and replacing ‘Planning Policy Wales, 2002’ and ‘Ministerial Interim Planning<br />
Policy <strong>Statement</strong>s’ issued between 2002 and 2009. This policy aims to reconcile the needs of<br />
development and conservation while protecting natural resources and the historic environment.<br />
Friars Walk, Newport<br />

Heritage_06_EF.docx
This document also provides the policy framework for the effective preparation of local planning<br />
authorities’ development plans.<br />
14.8. Chapter 6: Conserving the Historic Environment, outlines the importance of protecting the historic<br />
environment, encompassing ‘archaeology and ancient monuments, listed buildings, conservation<br />
areas and historic parks, gardens and landscapes’. Specific relevant objectives within this chapter<br />
include to:<br />
• preserve or enhance the historic environment, recognising its contribution to economic vitality<br />
and culture, civic pride and the quality of life, and its importance as a resource for future<br />
generations; and specifically to<br />
• protect archaeological remains, which are a finite and non-renewable resource, part of the<br />
historical and cultural identity of Wales, and valuable both for their own sake and for their role in<br />
education, leisure and the economy, particularly tourism; and to<br />
• ensure that the character of historic buildings is safeguarded from alterations, extensions or<br />
demolition that would compromise a building’s special architectural and historic interest.<br />
14.9. Paragraph 6.4.1 refers to development plans in regard to the historic environment and states that<br />
Development plans should reflect national policies for the preservation and enhancement of the<br />
historic environment. Development plans should also set out proposals for re-use or new<br />
development affecting historic areas and buildings, which may assist in achieving the Assembly<br />
Government’s objectives for urban regeneration.<br />
14.10. PPW4 is supplemented by a series of Technical Advisory Notes (TANs) 4 which provide advice on<br />
Retail Information, Change of use, Impact Assessments and <strong>Environmental</strong> Assessments.<br />
Local Planning Policy<br />
Adopted Newport Unitary Development Plan (UDP) 1996 - 2011 5<br />
14.11. Newport City Council’s (NCC) Newport Development Plan (UDP) 1996-2011 was formally adopted<br />
in May 2006. The UDP is the development plan for the whole of the Newport County Borough<br />
area. The following policies are considered of relevance to the Site with regard to archaeology and<br />
built heritage;<br />
• Policy SP7: Conservation of the natural environment;<br />
• Policy SP9: Conservation of the built environment;<br />
• Policy CE6: National sites;<br />
• Policy CE15: Listed buildings;<br />
• Policy CE20: Conservation areas;<br />
• Policy CE24: Shop fronts in conservation areas;<br />
• Policy CE25: Ancient monuments and archaeological remains;<br />
• Policy CE26: Archaeologically sensitive areas;<br />
• Policy CE27: Archaeological evaluation.<br />
14.12. Policy CE15, in particular, states that “buildings of special architectural or historic interest, their<br />
settings and features of architectural or historic interest will be protected and preserved”.<br />
14.13. Policy CE18 details matters that should be considered in proposals for development within a<br />
conservation area, and includes a requirement for the provision of information regarding the<br />

assessment of potential effects to the character and appearance of the conservation area.<br />
Furthermore, Policy CE20 describes criteria against which applications for the demolition of a<br />
building within a conservation area will be considered, which include “…iv) The contribution of the<br />
existing building to the character or appearance of the area, in relation to the potential merits of any<br />
replacement scheme, in preserving or enhancing the character or appearance of the area”.The Site<br />
is located within an ‘Archaeologically Sensitive Area’ (Newport Town Centre) Policy CE26 states<br />
that: Details of all proposed ground works and services, along with a written assessment of the<br />
likely archaeological impact of the development (archaeological statement) will be required.<br />
14.14. Newport City Council is in the process of creating a Local Development Plan (LDP) which will guide<br />
planning in Newport to 2026. Once adopted, this document will replace the existing UDP detailed<br />
above.<br />
Assessment Methodology and Significance Criteria<br />
Assessment Methodology<br />
14.15. The aim of this chapter is to provide a summary of known heritage assets in the Site and its<br />
immediate area, based on existing data and the analysis of historic sources. The likely nature of<br />
heritage assets and their settings which may face an effect by the proposed Development is<br />
outlined. The potential for both direct and indirect effects by the Development proposal are<br />
assessed.<br />
14.16. An Archaeological Desk-Based Assessment was undertaken in 2005 by Glamorgan-Gwent<br />
Archaeological Trust in relation to previous redevelopment proposals at the Site. This desk based<br />
assessment is reproduced as Technical Appendix 14.1 for ease of reference. It should be noted<br />
that this report was prepared by Glamorgan-Gwent in relation to a previous planning<br />
application for the Site and as such the discussion on archaeological effects is not valid or<br />
applicable to this EIA and has been disregarded. The baseline section of this report has<br />
however been validated by Waterman EED Ltd and found to be sound and valid for the purposes of<br />
informing this assessment. It is noted that the site boundary for the aforementioned report is not<br />
consistent with that of the planning application and the records information was obtained in 2005.<br />
A search has therefore been undertaken of the most up to date records from the Glamorgan-Gwent<br />
Historic Environment Record to supplement this study. These records included the full Site area as<br />
defined by the planning application boundary.<br />
14.17. The assessment therefore included following:<br />
• A review of the current legislative framework and requirements, as well as policy considerations;<br />
• An examination of relevant publications, articles, historic maps and plans held by Gwent Record<br />
Office and Newport Central Library’s local history collection;<br />
• A review of work undertaken to date in relation to the Site, including the 2005 Glamorgan-Gwent<br />
Archaeological Trust Archaeological Assessment (Technical Appendix 14.1) and a Written<br />
Scheme of Investigation previously prepared by Waterman CPM (Technical Appendix 14.2);<br />
• The collation of listed building data and information on Conservation Areas from Newport City<br />
Council;<br />
• An assessment of relevant and most up to date data from the Glamorgan-Gwent Historic<br />
Environment Record;<br />
• A walk-over survey to define the Site and area’s historic environment, particularly in relation to<br />
built heritage;<br />

• Consultation with the Newport City Council Conservation Officer;<br />
• An evaluation of the likely effects of previous Development on the Site;<br />
• An evaluation of the likely effects of the proposed Development; and<br />
• An assessment of the need for, and scope of, further investigation and mitigation measures.<br />
14.18. The assessment follows best practice procedures produced by Cadw 6 and the Institute for<br />
Archaeologists 7 . Planning Policy Wales (Chapter 6) recommends that where archaeological<br />
remains of national importance are affected by a proposed development, there should be a<br />
presumption in favour of their physical preservation. Where important remains are known or<br />
believed to exist, the development of sympathetic designs can also significantly minimise damage<br />
and help preserve remains beneath buildings or landscaping.<br />
14.19. The value of heritage assets facing effects by the Development are weighed up using the<br />
knowledge obtained from the documentary research, the walk over survey, knowledge of heritage<br />
assets derived from heritage investigations in the area, and through recognition of the topography,<br />
geomorphological processes and geology local to the Site (inference with similar environmental<br />
and topographic situations can suggest the type of heritage asset that may be expected).<br />
14.20. The survival of heritage assets is weighed up by assessing the effects of historical development on<br />
the Site (from documentary research), through information on the existing development on the<br />
existing Site (making inferences with similar developments and their known effect on heritage<br />
assets) and through recognition of the topography, geomorphological processes and geology local<br />
to the Site (inference with similar environmental situations can suggest the type of effect on the<br />
likely heritage assets that may be expected and the level of vulnerability of different types of<br />
heritage asset to development activity that may be expected).<br />
14.21. The assessment of the value of the Site’s heritage assets’ value and the effect of the Development<br />
on surrounding heritage assets’ value takes into account relevant historic building designation<br />
descriptions, the size and form of the proposed Development, the size and form of existing<br />
development and the Site’s historical development.<br />
14.22. The significance criteria below are a graduated scale of degrees of effect of the Development on<br />
receptors cross-referenced, using technical judgement, with the level of value of heritage assets<br />
that are known to be, or are likely to be present in and around the Site.<br />
Significance Criteria<br />
• Substantial adverse effect(s) - Where heritage assets of national value and/or their settings<br />
will be entirely destroyed. This would include a long term negative effect on the setting or<br />
structure of a Grade I/II* listed building or the demolition of any grade of listed building;<br />
• Moderate adverse - Where heritage assets of less than national value and/or their settings will<br />
be entirely destroyed. Where heritage assets of national value and/or their setting will face<br />
some damage. This would include the long term change to the setting or structure of a Grade II<br />
listed building, encroachment upon a conservation area that would have a clear negative effect<br />
on its character(s), and the slight change to the long term setting or structure of a Grade I/II*<br />
listed building;<br />
• Minor adverse - Where the value of heritage assets and/or their settings will be damaged. This<br />
would include slight change to the long term setting or structure of a Grade II listed building,<br />
demolition of an undesignated historic building, limited encroachment upon a conservation area<br />
that would have some negative effect on its character(s);<br />

Heritage_06_EF.docx
• Negligible - Where there is minimal effect on the value of heritage assets and/or their setting,<br />
or there are no heritage assets or settings that are facing any effect on their value;<br />
• Minor beneficial effect(s) - Where the development has a minimal effect on heritage assets’<br />
value and/or their settings, but provides new information on those heritage assets;<br />
• Moderate beneficial - Where the development has negligible or no negative effect on the value<br />
of heritage assets and/or their settings, provides new information on those heritage assets and<br />
enhances the settings and the management of the heritage assets;<br />
• Substantial beneficial - Where the development has no negative effect on the value of<br />
heritage assets and their settings, provides new information on those assets and enhances the<br />
value of the heritage assets, their settings and management, particularly in regard to nationally<br />
and internationally valued heritage assets.<br />
Baseline Conditions<br />
14.23. The following summarises the most pertinent, known and up to date heritage information relating to<br />
the Site. The locations of known heritage assets recorded on the Glamorgan-Gwent HER within<br />
and around the Site are tabled in the desk-based Archaeological Assessment included as<br />
Technical Appendix 14.1. Relevant plans showing historical maps and the location of heritage<br />
assets are also shown in Technical Appendix 14.1. The Glamorgan-Gwent HER was revisited in<br />
December 2011 and no new, relevant data was apparent.<br />
Designated Assets<br />
Scheduled Monuments<br />
14.24. There are no Scheduled Monuments (SM) within or around the Site. Newport Castle is a SM (and<br />
grade ll* listed building) and is situated just outside the Town Centre Conservation Area (see<br />
below).<br />
Archaeologically Sensitive Areas<br />
14.25. The Site is wholly located within one of four Archaeologically Sensitive Areas (ASA) identified by<br />
Newport City Council. This designation highlights the areas of archaeological significance and<br />
informs potential developers of the need to seek professional archaeological advice to establish the<br />
archaeological constraints of the site. The ASA including the Site notes the potential and known<br />
remains relating to the historic core of Newport and the historic riverside. In particular, in terms of<br />
the Site, it relates to the medieval Augustinian Friary and the medieval port (the ‘Town Pill’).<br />
Conservation Areas<br />
14.26. The north-west side of John Frost Square lies with the Town Centre Conservation Area, and the<br />
Lower Dock Street Conservation Area lies within 100m of the Site. The location of these<br />
Conservation Areas is shown on Figure 13.1. Further discussion on this the Conservation Areas is<br />
presented below.<br />
14.27. The Town Centre Conservation Area extends from near the junction of High Street with the Old<br />
Green Crossing road junction in the north to the junction of Commercial Street and Hill Street in the<br />
south. Either side of this spine the conservation area takes in numerous historic streets and<br />
buildings (many of them listed) including shopping arcades, a large indoor market, pubs, banks and<br />
a variety of retail and commercial buildings.<br />
Friars Walk, Newport<br />

Heritage_06_EF.docx
14.28. The north-western boundary of the Lower Dock Street Conservation Area (LDSCA) is located<br />
approximately 100 metres south-east of the Site. It is characterised by two storey brick, residential<br />
buildings built in the late nineteenth century. Views between the Site and the LDSCA are partially<br />
screened by the Newport Leisure Centre. The LDSCA contains over 240 houses and many<br />
commercial buildings ranging from traditional shops and offices to a Masonic Hall, a former<br />
customs house, a cattle market and an a drill hall. Ten buildings are listed Grade ll.<br />
14.29. The St. Woolos Conservation Area (SWCA) is centred around the Grade I listed St Woolos<br />
Cathedral, approximately 0.5km south west of the Site.<br />
Listed Buildings<br />
14.30. There are no listed buildings within the Site. A number of nineteenth-century buildings have been<br />
designated as Grade II listed buildings on Commercial Street, including two banks, which stand at<br />
the corners of Llanarth Street (Lloyds TSB Bank, LB No. 23109) and Austin Friars (The Halifax, 25-<br />
26 Commercial Street, LB No. 23108). The location of these buildings is shown in Technical<br />
Appendix 14.1.<br />
Other Heritage and Archaeological Potential<br />
14.31. The underlying geology consists of completely weathered bedrock/alluvium over St Maughans<br />
Group Devonian Red Marl over mudstone/siltstone, over sandstone. Due to the previously<br />
developed nature of the Site sub-base material and made ground are present below hardstanding<br />
(refer to Chapter 11: Ground Conditions and Contamination for further details).<br />
Prehistoric, Roman and Saxon<br />
14.32. Whilst human activity is demonstrated from chance finds and monuments in Newport from, at least,<br />
the Neolithic period, the earliest recorded activity close to the Site is of Roman date. This is limited<br />
to a single piece of Roman pottery, considered to be residual, found in the fill of a medieval pit<br />
excavated in the north of the Site in 1989. The location of this pit is not recorded on the HER,<br />
although the excavator has confirmed that it lay in the north-eastern area of the bus station<br />
forecourt (N. Maylan, pers. comm.).<br />
14.33. Evidence of early medieval activity (AD 410-1066) in the area is focused on the establishment of a<br />
chapel to St Gwynllwg in the 6th century on Stow Hill, approximately 500m to the south-west of the<br />
Site, which was the site of the later Parish Church of St. Woolos. Records from the 11th century<br />
note that English merchants frequently visited the mouth of the Usk to trade, which suggests the<br />
establishment of a trading settlement in the area.<br />
Medieval<br />
14.34. A reference to the town of Newport is recorded in a charter of 1132 as Novus Burgus or ‘new town’.<br />
A castle was constructed near to St. Woolos Parish Church, on Stow Hill, in 1090. A new castle<br />
was built at a location near to the River Usk, approximately 300m north of the Site, in the early<br />
twelfth century. The medieval town of Newport appears to have had a planned layout, which was<br />
focused along the High Street south-west of the castle, approximately 200m north of the Site. The<br />
town was granted official status as a borough in 1385 and appears to have grown in size through<br />
ribbon development along Stow Hill approximately 100m to the west of the Site.<br />
14.35. A friary (a monastery of the Augustinian Order of Friars) was founded in Newport in 1377 set in six<br />
acres of land. A plan of Newport in 1762 shows a group of rectilinear buildings in the north of the<br />
Site, which are labelled as ‘The Fryers’. The 6” first edition Ordnance Survey map of 1882 shows<br />
Friars Walk, Newport<br />
Chapter 14: Archaeology - Page 6<br />

Heritage_06_EF.docx
the location of several of the buildings of the friary near to the north-east Site boundary. A<br />
refectory building is marked in the area currently occupied by the northern multi-storey car park.<br />
Seven skeletons were recorded during pipe-line excavations ‘beside’ Kingsway Road in 1933.<br />
These had been buried in a recognisably Christian manner and are likely to be part of the friary<br />
burial ground. Unfortunately their exact position is not known.<br />
14.36. A large inlet, the ‘Town Pill’, approximately 100m north of the Site, formed the focus of a medieval<br />
port. A quay and a well preserved boat, constructed between 1465 and 1466, are recorded<br />
approximately 100m to the north-east of the Site. The location of these suggests that the mouth of<br />
the Town Pill was either wider in the mid fifteenth century, or that the area to the south of it formed<br />
a strand that was utilised for ship-repair or construction.<br />
Post Medieval<br />
14.37. A documentary source from 1801 indicates that the friary buildings largely survived Dissolution in<br />
the mid sixteenth century and noted that the standing monastic buildings included “…several<br />
detached buildings…and a spacious hall…in freestone; the body of the church is dilapidated, but<br />
the northern transept is a small and elegant example of gothic architecture”. Many of the friary<br />
buildings were demolished when the Newport Corporation cleared the Site after purchasing it in<br />
1860, although some standing buildings may have survived until 1920, when the refectory building<br />
may be shown on the third edition Ordnance Survey map.<br />
14.38. Other than remains of the friary, there is no evidence of built structures within the Site in the<br />
eighteenth century.<br />
Industrial Age<br />
14.39. There is some limited development along the northern edge of the Site by the mid-nineteenth<br />
century with Llanarth Street and Friars Street in the north-east and centre of the Site. Further<br />
buildings and streets are shown in the south of the Site and the southern part of Dock Street has<br />
been constructed. The Monmouthshire Canal is shown running along the eastern Site boundary at<br />
the same date. By 1886 the Site has been extensively developed, including the construction of the<br />
rest of Dock Street in the north-west. An area of open land remained in the north-east of the Site<br />
around the earlier monastic buildings, which is labelled as Friars Field.<br />
14.40. A number of industrial sites of nineteenth and twentieth centuries have been seen within the Site.<br />
The area of ‘Friars Field’ is shown as a timber yard on the second edition Ordnance Survey map of<br />
1902. The area south-east of this includes the large building of an ‘Electricity Works’, which<br />
remains from 1902 until the mid-twentieth century. The whole area remained occupied by mixed<br />
residential, commercial and industrial buildings until the early 1960s, when the Site was cleared of<br />
all buildings and redeveloped for the bus station, commercial units, highways and the two large<br />
multi-storey car parks.<br />
14.41. This construction resulted in significant earthmoving and landscaping, including the excavation of<br />
basements beneath the car park buildings. Some made ground appears to have been deposited in<br />
the area of John Frost Square, although it is clear that some excavation must have been required<br />
for construction of access roads to the Monmouthshire Building Society building and under the<br />
Winllan Building, which forms the north-west side of John Frost Square. The road under the<br />
Kingsway Centre’s multi-storey car park is, in part, subterranean. It has not been possible to<br />
identify whether basements exist beneath the commercial buildings in the north-west of the Site.<br />
Archaeological trial trenching undertaken in 1989 (GGHER E000369) demonstrated that land in the<br />
north-east of the Site had been disturbed through clearance for construction of the bus station (N.<br />
Friars Walk, Newport<br />

Maylan pers. comm.). The investigation identified no artefacts or features associated with the friary<br />
or the medieval port. Any archaeological remains in this area of the Site might be expected to be<br />
truncated and fragmentary. As such, they would not be considered as of more than local value.<br />
Some evidence for preservation of features of medieval date was identified near to the northwestern<br />
edge of the bus station forecourt where, a medieval pit was identified.<br />
14.42. In summary, potential for the presence of remains of a medieval friary has been identified in the<br />
north of the Site some of which is covered by the current buildings. The evidence of the<br />
development of the Site and previous archaeological investigation suggests that these remains will<br />
have been disturbed and would be expected to be truncated and fragmentary, with potentially<br />
limited areas of survival. As such, these would not be considered as of more than local value, but if<br />
any areas did survive in any great extent, they could be considered of greater than local value.<br />
14.43. Sub-surface remains of post-medieval structures may remain elsewhere in the Site. These would<br />
not be considered as of more than limited local value, given the level of disturbance that they will<br />
have been subjected to.<br />
Historic Built Environment<br />
14.44. Buildings are currently located in the southern and western parts of the Site, while highways<br />
structures and the bus station forecourt occupy most of the northern and eastern areas.<br />
14.45. The Town Centre Conservation Area (TCCA), as designated by Newport City Council, is located<br />
immediately to the north, west and south-west of the Site (refer to Figure 13.1). This designated<br />
area includes a large commercial building within the Site (occupied by Iceland) that forms the<br />
north-western side of John Frost Square. This is a utilitarian structure of Brutalist styling<br />
constructed in the 1960s, it is not representative of the general character of the TCCA which is<br />
dominated by late nineteenth and early twentieth-century commercial and retail buildings with the<br />
attendant lavish architectural detailing and polychromatic finishes (red brick, brown brick and stone<br />
predominating). It is likely that it has been included solely due to having a Commercial Street<br />
frontage and is highly unlikely to be identified as a positive building in any subsequent conservation<br />
area appraisal. Newport City Council note on their website that:<br />
“Most of the buildings that we see in this area today date to the Victorian and Edwardian<br />
periods, which is when the growth of Newport was at its height… much of the character and<br />
appearance of the conservation area derives from the architecture of the impressive three and<br />
four storey commercial buildings. Looking above the shop fronts the observant visitor will note<br />
a wealth of architectural detail that in many cases remains substantially unaltered. The large<br />
number of listed buildings within the conservation area bears testament to the exceptional<br />
quality of much of the surviving Victorian and early 20th century architecture.”<br />
14.46. No other buildings subject to the Development proposal are within any Conservation Area.<br />
14.47. There are no listed buildings within the Site. The remaining non-designated buildings within the<br />
Site include twentieth-century commercial structures, multi-storey car parks and Newport Bus<br />
Station. These were all constructed in the 1960s and later, although parts of the earlier late<br />
nineteenth-century street plan are preserved. The course of Kingsway is shown in the east of the<br />
Site on the Tithe map of 1841. This also depicts Llanarth Street aligned north-east to south-west<br />
across the Site. The existing Upper Dock Street preserves a small part of its original alignment,<br />
which was created between 1887 and 1902, however, other streets that formerly crossed the Site<br />
(including Merchant Street, Friar Street and Llanarth Street), were blocked by the redevelopment of<br />
the 1960s.<br />
Friars Walk, Newport<br />
Chapter 14: Archaeology - Page 8<br />

Heritage_06_EF.docx
14.48. The post 1960 structures clearly disrupted the character of the nineteenth-century streets in the<br />
Site. Furthermore, where there is a visual connection to the TCCA, they have no better than a<br />
neutral effect on its setting. However, views between the Site and the TCCA are generally<br />
screened by four storey buildings on Commercial Street and on the south-west side of John Frost<br />
Square and Upper Dock Street, although this screening is reduced to the higher ground in the<br />
conservation area further to the south-west. Views between the Site and the TCCA to the north are<br />
screened by buildings of three storeys with attics between Corn Street, Skinner Street and Upper<br />
Dock Street. Chartist Tower, a 17 storey brick and concrete building constructed in 1966,<br />
dominates views towards the north-west within the TCCA.<br />
14.49. A piece of public art, a clock tower, built in 1992 for the Welsh Garden Festival and named ‘The<br />
Nick of Time’, stands in John Frost Square. It is undesignated, being neither listed or falling within<br />
a Conservation Area.<br />
14.50. The TCCA major street, Commercial Street, contains many nineteenth-century buildings, six of<br />
which have been designated as Grade II listed buildings (see ‘Listed Buildings’ above). A late<br />
nineteenth-century public house, The Potters, is located immediately in the north-west of the Site,<br />
on the south-east side of Corn Street. The structure includes a west wing, formed in red brick<br />
above the ground floor storey and segmented by columns of a pale stone. It is three storeys plus<br />
attic, with façades on Corn Street and Upper Dock Street. The eastern part of this building is two<br />
storeys only and is rendered with a slate roof. Both parts of the building exhibit twentieth-century<br />
alterations, particularly through the insertion of later twentieth-century windows. It retains some<br />
value as a heritage asset, being an example of a late nineteenth-century public house that reflects<br />
some of the character of the Victorian development of the centre of Newport. However, its phased<br />
development and later alterations would mean that its value is not high and this is reflected by its<br />
exclusion from TCCA designation.<br />
14.51. The Riverside Arts Centre, constructed in 2004, stands to the north-east of the Site, next to the<br />
UDEX building, which is a converted nineteenth-century brown-brick warehouse. Despite the<br />
highly modern design of the Riverside Arts Centre, it does not have a negative effect on the more<br />
traditional building directly to the south-east of it.<br />
14.52. Buildings immediately to the south-west, south and south-east of the Site are all of later twentieth<br />
and twenty-first-century construction, including the Newport Art Gallery and Museum, the Kingsway<br />
Centre/Sovereign Arcade and the Newport Leisure Centre. These have roof lines that of the order<br />
of one third to one half higher than the existing buildings on the Site.<br />
Potential Effects<br />
Demolition and Construction Effects<br />
Buried Heritage/Archaeology<br />
14.53. Potential effects on archaeology would result from the excavation associated with construction of<br />
the basement, though this is minimal, since the proposal almost exclusively uses the formation<br />
levels of the existing buildings as they terrace into the land away from the river, and foundations of<br />
buildings across the Site. The evidence of historic maps and archaeological investigations<br />
suggests that any valuable archaeological remains that might survive would be confined to the<br />
north-western parts of the Site. Nineteenth and twentieth-century development of the Site would<br />
suggest that disturbance of archaeological deposits of medieval and Roman date is likely to have<br />
reduced its archaeological potential.<br />
Friars Walk, Newport<br />
Chapter 14: Archaeology - Page 9<br />
Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.14 Archaeology and Built Heritage\Chapter 14_Archaeology and Built<br />
Heritage_06_EF.docx
14.54. However, some areas of archaeological deposits may remain in the north-western part of the Site.<br />
It is not clear how damaged these are by the developments of the nineteenth and twentieth<br />
centuries. If surviving to any great extent in unfragmentary and truncated form, such remains<br />
(predominantly relating to the medieval port and the Augustinian Friary, in particular the potential<br />
for a medieval cemetery in the Site) could be considered of more than local importance. If present<br />
effects to these remains resulting from the proposed Development could therefore be considered<br />
as moderate adverse in the absence of mitigation. With this in mind, further archaeological<br />
investigation in the form of trial trenching would be required. These investigations would need to<br />
focus on the north-western part of the Site in line with the Written Scheme of Investigation already<br />
approved by Newport City Council. Refer to Mitigation Measures section for further details.<br />
14.55. Other archaeological remains of post-medieval and industrial age date would be considered as<br />
being of less importance, especially given that it is more probable that they have already been<br />
subject to significant disturbance as a result of the 1960s redevelopment of the Site. Effects to<br />
these remains of limited local importance would be considered as no greater than a minor adverse<br />
effect.<br />
Built Heritage/Historic Buildings<br />
14.56. The demolition of the existing utilitarian 1960s buildings on the Site represents a loss of structures<br />
that form part of the commercial and retail history of Newport in the second half of the twentieth<br />
century. This loss could be considered as a minor adverse effect a worst, but it can be readily<br />
mitigated. Their loss would, however, temporarily improve the setting of the TCCA and LDSCAs to<br />
the south-west, north-west and south-east of the Site, this would be considered a temporary minor<br />
beneficial effect. No effects are anticipated to the SWCA.<br />
14.57. In built heritage terms The Potters public house would be considered as being no greater that local<br />
importance due to its multi-phasing and later twentieth-century alterations. The proposal to partial<br />
demolish this building would be described as minor adverse, but can be entirely mitigated.<br />
Completed Development<br />
Buried Heritage/Archaeology<br />
14.58. No effects on archaeological remains are expected from the completed Development. As such<br />
effects can be considered negligible.<br />
Conservation Areas<br />
14.59. The proposed buildings in the north of the Site would be of a similar height to the structures on the<br />
north-west side of Corn Street, which would screen any views between the new buildings and the<br />
TCCA, further to the north-west. The mass of buildings to the south-west of the Site would screen<br />
views of the proposed buildings and the TCCA to the south-west. Where the TCCA area lies on<br />
higher ground, further to the south-west, and screening by intervening buildings is less effective,<br />
the standard of the proposed structures would still represent a significant improvement of the effect<br />
of the current car park buildings on the setting of the TCCA. Overall, the effect to the TCCA would<br />
therefore be considered as negligible.<br />
14.60. None of the proposed Development has a significantly large increase in height compared to the<br />
current buildings in the Site. The existing Chartist Tower, which currently dominates the area<br />
around the Site and overshadows adjacent built heritage resources, will continue to do so and the<br />
later twentieth and twenty-first century buildings to the east, south-east and south of the Site would<br />
maintain roof lines in excess of one quarter to one third higher than the roof lines of the proposed<br />
Friars Walk, Newport<br />

Development. While the slight increase in height could represent a minor adverse effect on nearby<br />
built heritage resources, it is not significantly greater than the current buildings purely in terms of<br />
massing and through the implementation of sophisticated design and use of modern materials,<br />
would at least offset this potential effect. As such, it is considered that the proposed Development<br />
would represent a negligible effect on built heritage resources, including listed buildings, in the<br />
centre of Newport.<br />
14.61. The proposed car park and retail units in the south of the Site would be constructed to modern<br />
design and buildings standards and would replace the utilitarian 1960s car parks. Any effect on the<br />
setting of the LDSCA resulting from the construction of these structures would be no more<br />
significant than the effect of the existing car parks and could be beneficial, particularly through the<br />
improved potential to support the economic viability of the area. The overall effect of the<br />
development to the LDSCA would be no worse than negligible.<br />
14.62. Although the SWCA is elevated, much of the Site is screened from the SWCA and the proposed<br />
Development with similar massing would have no greater an effect than the existing buildings<br />
(therefore negligible).<br />
Listed Buildings<br />
14.63. There is some potential for indirect effects to the settings of two of the listed buildings identified on<br />
Commercial Street. These are Lloyds TSB Bank and the Halifax (25-26 Commercial Street), which<br />
both occupy corner locations with views of the Site. The settings of both are already affected by<br />
buildings within the Site. The potential effect of new structures proposed within the Development<br />
on the settings of these two buildings would be negligible and, particularly in the case of the<br />
Halifax, the proposed Development could even represent a minor beneficial effect. The settings<br />
of the other listed buildings identified to the west of the Site would not be affected by the<br />
Development, i.e. would be negligible.<br />
Other Heritage Assets / Historic Features<br />
14.64. The Development would allow the reinstatement of both Dock Street and Llanarth Street, which<br />
were important nineteenth-century thoroughfares that were blocked by development in the 1960s.<br />
Reinstating sections of the historic street pattern would deliver a moderate beneficial effect.<br />
14.65. With regard to the Corn Street frontage, the existing buildings do not lie within the TCCA and are<br />
not listed. Proposed new structures in this area are restricted to the bus station buildings<br />
themselves, which are of a height in keeping with the surrounding built form. Therefore, it can be<br />
considered that the Development would have a negligible effect on the existing public house<br />
directly north-west of the Site and the nineteenth-century buildings standing on the north-west side<br />
of Corn Street.<br />
14.66. In built heritage terms, ‘The Nick of Time’ would be considered as being of no greater than local<br />
importance. As such, its removal and replacement by NCC in a new location would represent a<br />
negligible to minor beneficial effect on this particular built heritage resource. Depending on<br />
where it is placed, its setting could be improved.<br />

Heritage_06_EF.docx
Demolition and Construction<br />
Buried Heritage/Archaeology<br />
14.67. Effects on buried archaeological remains would be further quantified post demolition in the northwestern<br />
part of the Site by further archaeological investigations. This would be secured by an<br />
appropriately worded condition on any planning consent. A specification for archaeological field<br />
evaluation was prepared by Waterman CPM Ltd in 2006 in relation to previous development<br />
proposals for the majority of the Site. These proposals had a similar likely effect on the historic<br />
environment as the current proposed Development, namely on the north-western area of the Site<br />
where there is some potential for the survival of buried assets. This Written Scheme of<br />
Investigation was agreed with Newport City Council is included at Technical Appendix 14.2. The<br />
‘2006 WSI’) is considered to remain applicable to the current Development as proposed and sets<br />
out a programme of archaeological trial trenching in the north-western part of the Site to be carried<br />
out post demolition and pre-construction.<br />
14.68. For the remainder of the Site, effects would be mitigated by an appropriate programme of<br />
archaeological monitoring and recording during ground works and, as necessary, during<br />
demolition. Such a programme could be secured by an appropriate condition on any planning<br />
consent.<br />
Built Heritage/Historic Buildings<br />
14.69. The demolition of the existing 1960s buildings on the Site represents a loss of structures that<br />
represent part of the commercial and retail history of Newport in the second half of the twentieth<br />
century. This loss would be mitigated by an appropriately worded condition on any consent that<br />
secures a programme of rapid archaeological recording of these structures prior to demolition<br />
(predominantly the formation of a photographic record).<br />
14.70. Instead of demolition, ‘The Nick of Time’ would be removed to a suitable location to be agreed with<br />
NCC. No other mitigation measures are required at the demolition and construction phases of the<br />
Development.<br />
Completed Development<br />
Buried Heritage/Archaeology<br />
14.71. There are no effects expected from the completed Development on buried heritage / archaeology.<br />
As such no mitigation is proposed.<br />
Built Heritage/Historic Buildings<br />
14.72. No mitigation measures are considered in relation to the completed Development as no adverse<br />
effects are identified. Nonetheless, a programme for the provision of public art, as part of the wider<br />
city centre Masterplan area, would be prepared. This would include details of how the provision of<br />
public artwork within the Site is to be addressed and would include the re-siting of the ‘Nick of<br />
Time’ clock. The re-siting of this clock would be the responsibility of NCC.<br />

Heritage_06_EF.docx
Residual Effects<br />
Demolition and Construction<br />
Buried Heritage/Archaeology<br />
14.73. This assessment has identified that the potential for significant archaeological remains within the<br />
Site is limited to potential for elements of the medieval port to extend into the Site and remains of a<br />
medieval friary, in particular its associated cemetery, with even less quantified potential for Roman<br />
remains. This potential is limited to the north of the Site, with the likely area for the potential<br />
survival of less fragmentary and truncated remains restricted to the north-western part of the Site.<br />
Further archaeological investigations would therefore be undertaken in accordance with the WSI<br />
previously agreed with Newport City Council (included at Technical Appendix 14.2) following<br />
demolition of the on-Site buildings to quantify the heritage potential and the Development’s effects<br />
on these possible archaeological remains.<br />
14.74. There is only limited potential for the survival of isolated areas of sub-surface archaeological<br />
remains in the remaining part of the Site. These fragmentary remains would not be considered as<br />
of more than local importance and would most likely relate to post medieval and industrial age<br />
assets (e.g. the sawmill and electricity works). Disturbance of these remains would be mitigated<br />
through a programme of archaeological monitoring and recording during ground works in areas<br />
where it is considered that there is potential for their survival. This could be secured by an<br />
appropriately worded condition on any planning consent.<br />
14.75. Assuming the mitigation strategy suggested and those anticipated in the light of the advised further<br />
archaeological investigations identifying archaeological deposits that justify preservation in situ are<br />
adopted, the residual effects of the Development on archaeology in the north-western part of the<br />
Site would be minor adverse. Effects in the remainder of the Site would be negligible.<br />
Built Heritage/Historic Buildings<br />
14.76. The Site lies close to two Conservation Areas, one of which includes a building that lies within the<br />
north-western part of the Site. This building is not considered to be of any architectural or historic<br />
interest and there are no listed buildings within the Site. Effects on the SWCA are anticipated to be<br />
negligible.<br />
14.77. Demolition of the existing unattractive, utilitarian 1960s multi-storey car parks, retail units and a bus<br />
station is considered to represent a negligible effect following recording of these buildings prior to<br />
their removal. This is due to the fact that none of the buildings on Site are of architectural interest<br />
and their historic interest relates only to their part in the commercial and retail history of Newport in<br />
the second half of the twentieth century.<br />
Demolition of the existing structures would represent a temporary minor beneficial effect on the<br />
TCCA and the LDSCA. Completed Development<br />
Buried Heritage/Archaeology<br />
14.78. No potential effects are identified on buried heritage or archaeology from the completed<br />
Development therefore residual effects would be negligible.<br />

Heritage_06_EF.docx
Conservation Areas<br />
14.79. It is considered that structures proposed as part of the Development would have no worse than a<br />
negligible effect on the two Conservation Areas.<br />
14.80. As outlined under Potential Effects, the Development is to be constructed in modern new materials<br />
with a sophisticated design and would represent an improvement upon the 1960s’ concrete<br />
structures that it would replace. As such, the erection of this building would represent no worse<br />
than a negligible effect upon the Conservation Areas for which no mitigation is required or<br />
proposed.<br />
Listed Buildings<br />
14.81. It is also considered that the Development would not have any worse than a negligible effect on<br />
the settings of two listed buildings on Commercial Street within view of the Site. These are Lloyds<br />
TSB Bank and the Halifax (25-26 Commercial Street), which both occupy street corner locations<br />
with view of the Site. The settings of both are already affected by the current buildings within the<br />
Site. The residual effect of new structures proposed within the Development on the settings of<br />
these two buildings would be negligible and, particularly in the case of the Halifax, the proposed<br />
Development could even represent a minor beneficial effect.<br />
14.82. The settings of four other listed buildings within the TCCA were considered. There frontages are<br />
onto Commercial Street and other side streets away from the Site and, as such, are fully screened<br />
from the Development. It can be concluded that the Development would have no direct effect on<br />
their settings.<br />
14.83. The settings of the other listed buildings to the west of the Site would not be affected by the<br />
Development.<br />
Other Heritage Assets / Historic Features<br />
14.84. The reinstatement of historic thoroughfares would have a moderate beneficial effect on the built<br />
heritage.<br />
14.85. The removal of ‘The Nick of Time’ to a new location would represent a minor beneficial effect on<br />
this particular built heritage resource. Depending on where it is placed, its setting could be<br />
improved.<br />
14.86. The existing buildings on Corn Street do not lie within the TCCA0 and are not listed buildings.<br />
Proposed new structures in this area are restricted to the bus station buildings themselves, which<br />
are of a height in keeping with the surrounding built form. Therefore it is considered that the<br />
Development would have a negligible effect on the existing public house, directly north-west of<br />
the Site, and the nineteenth-century buildings standing on the north-west side of Corn Street.<br />
14.87. With respect to the treatment of public art within the Site, it is considered that the proposed<br />
Development would have a negligible effect from the built heritage viewpoint. Although no<br />
mitigation is therefore required, as part of the City centre master plan, it is, nonetheless, intended<br />
that a programme for the provision of public art within the Site would be drawn up.<br />

15. Ecology<br />
Introduction<br />
15.1. This Chapter has been prepared by Waterman Energy, Environment & Design Limited (Waterman<br />
EED). It assesses the potential effects of the Development upon the ecological and nature<br />
conservation resources on, and in proximity to the Site.<br />
15.2. A description of relevant legislation and planning policies applicable to the Site are provided,<br />
together with the methods employed to assess the effects and the baseline conditions on, and<br />
surrounding the Site. The chapter then identifies any potential effects that the proposed<br />
Development may have during the demolition and construction works, and once completed and<br />
operational. In addition appropriate mitigation and enhancement measures are outlined and any<br />
residual and cumulative effects identified.<br />
15.3. The following technical appendices accompany this chapter:<br />
• Technical Appendix 15.1 – Extended Phase 1 Habitat Survey;<br />
• Technical Appendix 15.2 – Bat Survey Report;<br />
• Technical Appendix 15.3 –Habitat Regulations Assessment Screening Report.<br />
Legislation and Planning Policy Context<br />
Legislation<br />
15.4. Specific ecological resources, including habitats and species receive legal protection in the UK<br />
under various pieces of legislation, including:<br />
Wildlife and Countryside Act, 1981 (as amended)<br />
15.5. The Wildlife and Countryside Act (WCA), 1981 (as amended) 1 forms the key legislation protecting<br />
habitats and species in Great Britain. Sites of Special Scientific Interest (SSSIs), representing the<br />
best examples of our natural heritage, are notified under the Act.<br />
Conservation of Species and Habitats Regulations, 2010<br />
15.6. The Conservation of Habitats and Species Regulations 2010 (the ‘Habitats Regulations’) 2<br />
consolidate and update the Conservation (Natural Habitats &c.) Regulations, 1994 3 . The<br />
Regulations mainly deal with the protection of sites that are important for nature conservation in a<br />
European context. The notification of Special Areas of Conservation (SACs) is through the EC<br />
Directive on the Conservation of Natural Habitats and of Wild Flora and Fauna (92/43/EEC) 4 .<br />
However, they also give protection to certain species of flora and fauna. Relevant urban species to<br />
this assessment which receive protection under this legislation include all native European species<br />
of bat. The protection covers both the bats themselves and their roosts.<br />
The Countryside and Rights of Way Act, 2000<br />
15.7. The Countryside and Rights of Way Act, 2000 (CRoW) 5 strengthens the protection given to SSSIs<br />
and certain species under the WCA making it an offence to “recklessly disturb” the sheltering<br />
places of wild animals designated under Schedule 5 of the CRoW Act.<br />

The Natural Environment and Rural Communities Act, 2006<br />
15.8. The Natural Environment and Rural Communities Act, 2006 6 provides the statutory framework<br />
underpinning the Biodiversity Action Plan (BAP) process and promotes the conservation of the<br />
priority species and habitats listed in the UK BAP, 1994 (UK BAP). Further details are given later<br />
in this chapter.<br />
National Planning Policy<br />
Planning Policy Wales 2011<br />
15.9. National land use planning policy in Wales is set out in the fourth edition of ‘Planning Policy Wales’ 7<br />
published in February 2011 (PPW4).<br />
15.10. Chapter 5 of PPW4 is concerned with Conserving and Improving Natural Heritage and the Coast.<br />
Paragraph 5.1.2 sets out the Assembly Government’s objectives for the conservation and<br />
improvement of the natural heritage which are to:<br />
• promote the conservation of landscape and biodiversity, in particular the conservation of native<br />
wildlife and habitats;<br />
• ensure that action in Wales contributes to meeting international responsibilities and obligations<br />
for the natural environment;<br />
• ensure that statutorily designated sites are properly protected and managed; and to<br />
• safeguard protected species.<br />
15.11. Paragraph 5.5.4 refers to Development Control and the conservation and improvement of the<br />
natural heritage and states that:<br />
“For all planning applications likely to result in disturbance or harm to a protected species or<br />
likely to have a significant adverse effect on sites of more than local importance, or on a<br />
designated area, local planning authorities should seek the advice of CCW and should always<br />
consult them before granting permission.”<br />
15.12. PPW is supplemented by a series of Technical Advisory Notes (TANs). Tan 5 ‘Nature<br />
Conservation and Planning’ 8 provides advice about how the land use planning system should<br />
contribute to protecting and enhancing biodiversity and geological conservation.<br />
15.13. The Wales Biodiversity Partnership has published The Wales Biodiversity Framework 9 . This<br />
explains the roles, remits and processes essential to biodiversity conservation and enhancement in<br />
Wales. It provides a common point of reference on biodiversity for all organisations and individuals<br />
in Wales.<br />
Biodiversity Action Plans<br />
15.14. The UK Biodiversity Action Plan 10 lists a number of priority habitats and species for conservation<br />
action in the UK. Although the Action Plan does not confer any statutory legal protection, in<br />
practice many of the species listed already receive statutory legal protection under UK and/or<br />
European legislation. In addition, there are some Priority Species and Habitats in the UK<br />
Biodiversity Action Plans which are also Species and Habitats of Principal Importance for the<br />
Conservation of Biodiversity under Section 74 of the CRoW Act 2000. This places a duty on<br />
government departments to have regard for these species and habitats when carrying out their<br />
functions. The UK BAP Species and Habitats that are considered of relevance to the site include:<br />
• Common Pipstrelle Pipistrellus pipistrellus;<br />

Regional & Local Planning Policy<br />
Adopted Newport Unitary Development Plan (UDP) 1996 - 2011<br />
15.15. The Newport Unitary Development Plan (UDP) 1996-2011 11 was formally adopted in May 2006.<br />
The UDP is the Development Plan for the whole of the Newport County Borough area. Part I of the<br />
UDP contains strategic policies. Strategic Policy SP7 ‘Conservation of the natural environment’ is<br />
in relation to ecology and the natural environment and states:<br />
“The Newport County Borough area has a wealth of habitats and species and many features of<br />
nature conservation interest. A variety of designations also apply within the county borough,<br />
right up to sites of international importance. It is important to take care not to diminish the<br />
environmental resource, rather, wherever possible, to sustain and enhance biodiversity, for the<br />
benefit of generations now and to come. Attractive and ecologically rich environments, together<br />
with others that contribute to the special character of an area, for example through historic or<br />
cultural associations, should be protected both for their own sake and for the health and social<br />
and economic well-being of individuals and communities.”<br />
15.16. Part II of the UDP contains detailed policies. The following paragraphs set out the UDP’s relation<br />
to ecology and nature conservation.<br />
15.17. Policy CE4 ‘Landscaping Schemes’ states:<br />
“Planning applications for significant or prominent developments should be accompanied by a<br />
landscape design statement. The following will be sought, as appropriate:<br />
i) A design which reflects the local landscape character;<br />
ii) The use of tree and shrub species of local native provenance;<br />
iii) The retention of existing landscape features such as ponds, hedgerows and trees;<br />
iv) Implementation of some or all of the landscaping scheme before development commences<br />
where this is necessary to protect nature conservation or biodiversity interests.”<br />
15.18. Policy CE5 ‘International sites’ states:<br />
“In the case of development proposals which would affect a European site or a RAMSAR site:<br />
i) Where there would be an adverse effect, the development will only be permitted if it is<br />
directly necessary for the beneficial management of the site, or if there are imperative<br />
reasons of over-riding public interest for the development and there is no alternative solution;<br />
ii) Where the Site also hosts a priority natural habitat or a priority species, development will<br />
only be permitted if it is directly necessary for human health, public safety or is directly<br />
connected with the beneficial management of the site.”<br />
15.19. Policy CE6 ‘National Sites’ states:<br />
“Development which would affect a nationally designated site will only be permitted where:<br />
i) The proposal would not have an unacceptably adverse effect on the nature conservation<br />
interest of the site;<br />
ii) The reasons for the development clearly outweigh the value of the site itself and its value in<br />
the network of such nature conservation sites, and it is possible to agree conditions for<br />
mitigation of harmful effects in consultation with the Countryside Council for Wales.”<br />
15.20. Policy CE7 ‘Locally Designated Sites’ states:<br />
Friars Walk, Newport<br />
Chapter 15: Ecology - Page 3<br />

Ecology_HMB_071211_001.docx
“Development of locally designated sites will only be permitted where:<br />
i) There would be no significant adverse effect on the nature conservation or geological<br />
interests of the site;<br />
ii) There are demonstrable reasons for the proposal which outweigh the need to safeguard the<br />
nature conservation value of the site and appropriate mitigation or compensation measures<br />
can be achieved.”<br />
15.21. Policy CE9 ‘Species protected by European Legislation’ states:<br />
“Planning permission will not be granted for development which could disturb or adversely affect<br />
a species protected by European legislation unless:<br />
i) There is no alternative location for the proposed development and appropriate mitigation<br />
measures can be implemented;<br />
ii) It can be established on the advice of the relevant conservation bodies that the development<br />
proposed would not be detrimental to the protected species.”<br />
15.22. Policy CE10 ‘Species protected by United Kingdom Legislation’ states:<br />
“Planning permission will only be granted for development which could disturb a species<br />
protected by United Kingdom legislation where the harmful effects of the development can be<br />
mitigated or minimised to an acceptable level”.<br />
15.23. Policy CE13 ‘Trees and Hedgerows on Development Sites’ states:<br />
“Planning permission will only be granted for development which would damage or destroy one<br />
or more trees which are protected, or which are worthy of protection, or hedgerows which have<br />
amenity or wildlife value, where:<br />
i) There is demonstrable environmental, economic or social need for the development<br />
sufficient to outweigh the amenity and biodiversity value of the trees or hedgerows;<br />
ii) The trees or hedgerows can be replaced within the site boundary in a manner which ensures<br />
that there is no unacceptably detrimental impact upon the character and visual amenity of<br />
the area, nor to local biodiversity.”<br />
15.24. Newport City Council (NCC) is in the process of creating a Local Development Plan (LDP) which<br />
will guide planning in Newport to 2026. Once adopted, this document will replace the existing UDP<br />
detailed above.<br />
Cymru D / S Wales-Newport Biodiversity Action Plan<br />
15.25. As part of the action plan process, Local Biodiversity Action Plans (LBAPs) must also be produced<br />
for every county in the UK. The Site is covered by the Cymru D / S Wales-Newport LBAP 12 . This<br />
LBAP includes the following Species Action Plans (SAPs) and Habitat Action Plans (HAPs) that are<br />
considered of relevance to the site:<br />
• SAP - Otters Lutra lutra;<br />
• HAP – Urban.<br />

Assessment Methodology and Significance Criteria<br />
Assessment Methodology<br />
15.26. This section outlines the methodology used to assess the ecological baseline conditions of the Site<br />
and to place the Site in its wider ecological context. The assessment methodology has comprised<br />
the following:<br />
• Undertaking of an ecological desk-study (2011);<br />
• Undertaking of an Extended Phase 1 Habitat Survey (2011);<br />
• Building evening emergence and dawn re-entry survey for roosting bats (2011);<br />
• Evaluation of the ecological value of the Site;<br />
• Assessment of the likely direct and indirect effects of the Development during both the<br />

• Identification of any required mitigation and assessment of any residual effects.<br />
15.27. A description of the methodologies adopted for the relevant surveys is provided below. The study<br />
area is indicated by the red line boundary, set out in Figures 1.2 and 1.3.<br />
Delineation of the Study Area and Identification of the ‘Zone of Influence’<br />
15.28. The first stage of the assessment necessitated the delineation of an appropriate Study Area. This<br />
was defined as all land within 2km of the perimeter of the Site. The ecological Zone of Influence<br />
(ZoI) of the Development is largely confined to the area within the application site. However,<br />
consideration was given to any potential effects on statutory and non-statutory sites within 2km of<br />
the Site.<br />
Ecological Data Search<br />
15.29. The aim of the ecological data search is to collate existing ecological records for the Site and<br />
adjacent areas. Obtaining existing records is an important part of the evaluation process, as it<br />
provides additional information that may not be apparent during a site survey.<br />
15.30. Records of statutory and non-statutory sites within a 2km radius of the Site and protected species<br />
both of flora and fauna within a 2km radius of the Site were collated for the area. This information<br />
was obtained from the South East Wales Biodiversity Records Centre (SEWBREC).<br />
15.31. In addition, the Cymru D / S Wales-Newport LBAP was consulted for the habitats and species of<br />
value in the local area, to assign an ecological context to the Site. Key relevant ecological data is<br />
provided in Technical Appendix 15.1.<br />
Field Surveys<br />
Extended Phase I Habitat Survey<br />
15.32. An Extended Phase 1 Habitat Survey of the application Site was conducted on 26 th August 2011<br />
using the Joint Nature Conservancy Council (JNCC) standard ‘Phase 1’ survey techniques (at a<br />
level intermediate between the NCC Standard ‘Phase 1’ and ‘Phase 2’ Survey 13 ). The survey was<br />
used to determine the habitats present, the dominant plant species and any obvious faunal activity.<br />
The survey also aimed to identify the presence of, or potential for, protected species within and<br />

surrounding the Site. All habitat types within the survey area were mapped (see Technical<br />
Appendix 15.1).<br />
15.33. Based on the findings of the Extended Phase 1 Habitat Survey and ecological data search it was<br />
concluded that further surveys for bats would be required to support a full planning application.<br />
Bat Emergence/Re-entry Survey<br />
15.34. The Extended Phase 1 Habitat Survey (refer to Technical Appendix 15.1) of the Site conducted in<br />
August 2011 identified buildings B1, B2, B5 and B8 as having low potential to support roosting<br />
bats. Good practice guidelines (Bat Conservation Trust, 2007) 14 state that buildings with potential<br />
for bats should be subject to further surveys.<br />
15.35. To confirm the presence or likely absence of roosting bats within these buildings, a single dusk<br />
emergence and dawn re-entry survey (within the same 24 hour period) was undertaken. Four<br />
surveyors were situated at key locations to ensure that all aspects of the buildings were observed<br />
at all times. The dusk survey commenced 15 minutes before dusk and was completed two hours<br />
after dusk to cover a range of emergence times for different bat species. The dawn survey<br />
commenced 1.5 hours before dawn and 15mins thereafter to survey for bats returning to roost.<br />
15.36. Time expansion (Pettersson D240X) and frequency division (Batbox Duet) bat detectors were used<br />
by surveyors and data was recorded onto solid state MP3 recorders. Recorded bat calls were later<br />
analysed using BatSound 4.1.2.B software where required.<br />
15.37. Any bats observed were recorded, including those emerging or entering the buildings or flying in<br />
the local vicinity. Information included:<br />
• Time;<br />
• Emergence or re-entry points;<br />
• Direction of flight;<br />
• Use of landscape;<br />
• Flight characteristics;<br />
• Size;<br />
• Height; and<br />
• Behaviour.<br />
15.38. All surveys were undertaken in appropriate weather conditions and at a suitable time of year.<br />
Evaluation of Ecological Features<br />
15.39. The basis for the evaluation of ecological features is provided by the 2006 Institute of Ecology and<br />
<strong>Environmental</strong> Management (IEEM, 2006) 15 guidelines for Ecological Impact Assessment (EcIA).<br />
These guidelines aim to provide consistency in the approach to evaluating the importance of<br />
ecological features and any effect that a new development would have upon them.<br />
15.40. In accordance with the IEEM EcIA guidelines, the ecological features identified must be assigned a<br />
value. Secondly, the effects of the relevant development should be predicted, taking into account<br />
the different stages and activities within the development process. These identified effects must<br />
then be assessed for their significance. The significance of the effect is a function of the value of<br />
the ecological feature and the type and nature of the effect.<br />
15.41. The value of ecological features is defined according to the following geographical scales:<br />
Friars Walk, Newport<br />
Chapter 15: Ecology - Page 6<br />

Ecology_HMB_071211_001.docx
• International value;<br />
• UK value;<br />
• National value (i.e. England / Northern Ireland / Scotland / Wales);<br />
• Regional value;<br />
• County / Metropolitan value;<br />
• District / Borough value;<br />
• Local or Parish value;<br />
• Of value within the Site only; and<br />
• Negligible.<br />
15.42. IEEMs criteria are broadly similar to those set out in Chapter 2: EIA Methodology with the terms<br />
‘Local or Parish’ and ‘District / Borough’ equivalent to the ‘local’ and ‘Borough’ scale, and ‘County /<br />
Metropolitan’ equivalent to the ‘Regional’ scale. The remaining geographical scales are consistent<br />
with both methodologies.<br />
15.43. The following factors are considered in assessing whether ecological effects are significant:<br />
• The extent of the effect;<br />
• The magnitude of the effect;<br />
• The duration of the effect;<br />
• The reversibility of the effect; and<br />
• The timing and frequency of the effect.<br />
Evaluation of Significance<br />
15.44. In accordance with Chapter 2: EIA Methodology, the potential and residual effects of the<br />
Development upon identified ecological features are expressed as follows:<br />
• Adverse: Detrimental or negative effect on a valued ecological receptor;<br />
• Negligible: No significant effect on a valued ecological receptor; and<br />
• Beneficial: Advantageous or positive effect on a valued ecological receptor.<br />
15.45. Where adverse or beneficial effects have been identified, these are then assessed against the<br />
following scale:<br />
• Minor: Slight, very short or highly localised effect;<br />
• Moderate: Limited effect (by extent, duration or magnitude) which may be considered<br />
significant; and<br />
• Substantial: Considerable effect (by extent, duration or magnitude) of more than local<br />
significance or in breach of recognised acceptability, legislation, policy or<br />
standards.<br />
15.46. A ‘valued’ ecological receptor has been defined as any receptor valued at the Site level or above,<br />
in accordance with the geographical scales provided above.<br />
15.47. In accordance with IEEM guidelines, where activities associated with the Development could result<br />
in the intentional killing or injury of protected species, this is stated and a level of significance is not<br />
given. This is because such killing or injury must be avoided by law. For other activities that could<br />

15.52. The Site currently comprises a disused multi-storey car park, retail units, public open space within<br />
John Frost Square and the bus station.<br />
Habitats and Fauna<br />
15.53. Through the ecological data search and Extended Phase 1 Habitat Survey the flora and fauna on<br />
and adjacent to the Site was assessed for its ecological value. Further details are provided in<br />
Appendix 15.1.<br />
Hard Standing<br />
15.54. Hard standing is present around the majority of the Site in terms of infrastructure, pedestrian<br />
access to the retail units and a bus station. The majority of these areas are well lit at night as a<br />
result of street lighting. This habitat lacks any value for ecology and is therefore considered to be<br />
of negligible ecological value.<br />
Amenity Grassland<br />
15.55. There is a small patch of amenity grassland located in the east of the Site. Species recorded<br />
include ribwort plantain Plantago lanceolata, dandelion Taraxacum officinale and white clover<br />
Trifolium repens. Owing to this habitat type being small in area and isolated it is considered to be<br />
of negligible ecological value.<br />
Ornamental Planting<br />
15.56. There are several areas of ornamental planting across of the Site. The majority of these areas are<br />
located in the eastern part of the Site adjacent to the A4042 Kingsway/Usk Way and appear<br />
recently planted. Other areas include raised flower beds within John Frost Square in the west of<br />
the Site. Species recorded include firethorn Pyracantha sp., shrubby veronica Hebe sp., Euphoria<br />
sp., vibernum Vibernum sp., New Zealand flax Phormium sp., vinca Vinca sp., lavender Lavandula<br />
angustifolia and Erica sp.<br />

Ecology_HMB_071211_001.docx
15.57. The ornamental area located in the north of the Site adjacent to the A4042 Kinsgway/Usk Way has<br />
become overgrown, resulting in the colonisation of native species. Species recorded include<br />
hedge bindweed Calystegia sepium, bristly ox-tongue Picris echioides, black medic Medicago<br />
lupulina, hedge mustard Sisymbrium officinale, mugwort Artemisia vulgaris, broad leaved dock<br />
Rumex obtusifolius, Yorkshire fog Holcus lanatus, false oat grass Arrhenatherum elatius and cutleaved<br />
cranesbill Geranium dissectum.<br />
15.58. The ornamental habitat areas within the Site boundary are isolated from other habitats, but may<br />
offer foraging opportunities for common invertebrate and bird species. Therefore it is considered<br />
that this habitat is of value within the Site only.<br />
Scattered Trees<br />
15.59. Several areas of planted trees are located within the Site boundary. Species recorded include<br />
London plane Platanus × acerifolia, ash Fraxinus excelsior, purple maple Acer sp., sycamore Acer<br />
pseudoplatanus, tulip tree Liriodendron tulipifera and silver birch Betula pendula. These trees are<br />
likely to provide opportunities for local birds and common invertebrate species and as such it is<br />
considered that this habitat is of value within the Site only.<br />
Buildings<br />
15.60. A number of buildings are present within the Site boundary. These consist of retail units, office<br />
space, a multi-storey car park and bus station. The buildings were viewed externally and assessed<br />
against the Bat Conservation Trust Guidelines for their potential to support roosting bats. Buildings<br />
B3, B4, B6, B7 and B9 have been identified as having negligible potential to support bat roosts.<br />
Buildings B1, B2, B5 and B8, however, have been assessed as having low potential to contain<br />
roosting bats, refer to Appendix 15.2 for further details. Given the evidence recorded above the<br />
buildings are considered to be of value within the Site only.<br />
Bats<br />
15.61. A number of bat records were returned from the SEWBREC data search which are summarised in<br />
Table 4. Common pipistrelle Pipistrellus pipistrellus, soprano pipistrelle Pipistrellus pygmaes,<br />
noctule Nyctalus noctula, whiskered/brandt’s bat Myotis sp., nathusius’s pipistrelle Pipistrellus<br />
nathusii, and brown long-eared bat Plecotus auritus have been recorded in the area and it is<br />
considered that these species, which are known to be used to urban environments, could utilise the<br />
Site.<br />
15.62. The buildings on Site have been assessed against the criteria set out in BCT best practice<br />
guidelines for their potential to support roosting bats. Full details of building descriptions at the Site<br />
are provided in Appendix 15.2. Due to access restrictions the buildings were not subject to internal<br />
inspections during this survey. No evidence of roosting bats was found during the external<br />
inspection. However features such as gaps behind fascia boards and cracks in brickwork were<br />
noted during the exterior inspection of B1, B2, B5 and B8 resulting in these buildings being rated as<br />
having low bat roosting potential. However it should be noted that the Site is located in a highly<br />
urbanised area which is well lit at night, which decreases the likelihood of bat roosting activity. The<br />
remainder of the buildings on Site are not considered to have any suitable bat roosting features<br />
and therefore have negligible bat roosting potential.<br />
15.63. None of the trees present within the Site boundary have potential to support roosting bats. This<br />
was due to the absence of bat roosting features such as woodpecker holes and cavities. Therefore<br />
the trees on Site are considered to have negligible bat roosting potential.<br />

Ecology_HMB_071211_001.docx
15.64. Owing to the small size and isolation of the scattered trees and ornamental planting on Site, they<br />
are considered to provide sub-optimal foraging and commuting habitat for bats.<br />
15.65. During the emergence/re-entry survey no bats were observed emerging or entering any of the<br />
buildings on Site at the time of survey.<br />
15.66. Two common pipistrelle bat passes were recorded during the dusk emergence survey. Surveyor 1<br />
made a recording at 20:27:03 and surveyor 2 made a recording at 20:27:29. It is considered likely<br />
that both surveyors recorded the same individual bat passing through the Site.<br />
15.67. Overall, it is considered that the Site is of value within the Site only to bats.<br />
Birds<br />
15.68. There are numerous records of bird species within 2km of the Site.<br />
15.69. Several feral pigeons Columba livia were observed upon various buildings at the time of survey.<br />
15.70. The scattered trees and buildings have potential to support nesting birds during the breeding<br />
season (March-August inclusive). However, given the limited habitats of value to birds on Site, it is<br />
unlikely that any large or notable bird populations would be present. It is therefore considered that<br />
the Site is of value within the Site only to nesting birds.<br />
Invertebrates<br />
15.71. Numerous records of invertebrates were returned from the data search. However, due to the<br />
overall lack of flora species diversity in all habitats found within the Site boundary, it is considered<br />
unlikely that these habitats would support any rare or threatened species of invertebrate.<br />
Therefore, the value of the Site in relation to invertebrates is considered to be of value within the<br />
Site only.<br />
White-Clawed Crayfish<br />
15.72. The closest white-clawed crayfish Austropotamobius pallipes record is 1.8km north of the Site<br />
located in Gwasted Mawr.<br />
15.73. The habitats present on Site are not considered suitable to support white-clawed crayfish and<br />
therefore the Site is of negligible value to white-clawed crayfish and as such they are not<br />
considered further in this report.<br />
Otters<br />
15.74. The South East Wales Biodiversity Records Centre holds numerous records of otters Lutra lutra<br />
from within 2km of the Site.<br />
15.75. The River Usk is located approximately 50m east of the Site boundary. Otters are known to come<br />
to land to rest and rear their young utilising at least a 100m wide strip of bank or coast (IUCN,<br />
2009) 16 . On land they require habitat features such a tree roots, scrub and rock piles to create<br />
structures called holts and couches which provide otters with shelter. The habitats present on Site<br />
do not offer any potential features of value for otters. In addition the Site is separated from the<br />
River Usk by the A4042 Kingsway/Usk Way and other urban development located adjacent to the<br />
River Usk. It is therefore considered that the Site is of negligible value to otters and they are<br />
therefore not considered further in this report.<br />

Ecology_HMB_071211_001.docx
Water Voles<br />
15.76. One water vole Arvicola amphibius record is held by SEWBREC, dating from 1984 from within a<br />
water body located over 2km from the Site.<br />
15.77. Water voles utilise well vegetated banks of slow flowing water bodies (Strachan, 1997) 17 . Owing to<br />
the distance of the River Usk from Site, the lack of vegetation present on its banks and its high flow<br />
rate it is considered that the Site is of negligible value to water voles and therefore they are not<br />
considered further in this report.<br />
Reptiles<br />
15.78. The data search returned records of reptile species located over 1.2km from the Site. However,<br />
the Site is not considered to have the potential to support reptiles owing to a lack of ground<br />
vegetation cover and isolation from other suitable reptile habitat.<br />
15.79. The Site is therefore of negligible value for reptiles and consequently they are not considered<br />
further in this report.<br />
Amphibians<br />
15.80. No waterbodies considered to have potential to support breeding populations of great crested newt<br />
Triturus cristatus are present on or within 500m of the Site.<br />
15.81. No records for great crested newts were returned for the Site or within 2km of the site from the data<br />
search.<br />
15.82. The data search provided records of common species of amphibians, however, it is considered that<br />
the Site does not offer any habitat of value for the aquatic or terrestrial phases of these species.<br />
15.83. The Site is therefore considered to be of negligible value in relation to amphibians and therefore<br />
they are not considered further in this report.<br />
Cetaceans<br />
15.84. The data search provided two records of common porpoise Phocoena phocoena from the River<br />
Usk.<br />
15.85. The Site does not offer any suitable habitat for cetacean species and therefore the Site is<br />
considered to be of negligible value for cetaceans and consequently they are not considered<br />
further in this report.<br />
Other Protected/Notable Species<br />
15.86. The habitats present on Site are not considered suitable for any other protected or notable species.<br />
Potential Effects<br />
Demolition and Construction<br />
15.87. The Development has the potential to result in a number of ecological effects during the demolition<br />
and construction phase. Those relevant to the Site include:<br />
• Disturbance to the ecology of designated sites owing to construction operations, including<br />
noise, dust and vibration;<br />
• Habitat loss owing to land take and new built development;<br />
Friars Walk, Newport<br />
Chapter 15: Ecology - Page 14<br />

Ecology_HMB_071211_001.docx
• Changes in the pattern of human activity and associated disturbance and/or damage;<br />
• Disturbance to bats and birds due to construction operations, including noise, vibration, dust,<br />
surface water run-off and changing habitats throughout construction; and<br />
• Releases of sediments and / or contamination and / or fuels and chemicals into the surface<br />
water drainage system and ultimately the River Usk.<br />
15.88. The significance of these potential effects is assessed in the following section. Effects are<br />
assessed against the current baseline conditions.<br />
Designated Sites<br />
15.89. Owing to the scale and duration of the construction works associated with the Development, there<br />
are potential areas within the Zol which could be affected. The River Usk is of international value<br />
owing to its designation as an SAC and is located approximately 50m east of the Site boundary.<br />
15.90. The impacts upon the River Usk SAC during the demolition and construction phase have been<br />
discussed in detail in Technical Appendix 15.3 and a summary has been provided below.<br />
15.91. The potential impacts upon the River Usk SAC during the demolition and construction phase of the<br />
development are:<br />
• Barriers to migration;<br />
• Disturbance pressures; and<br />
• Diffuse pollution.<br />
15.92. It is considered that the proposed Development at the Site would not create any barriers to<br />
migration owing to the separation of the Site from the River Usk SAC. As such, the demolition and<br />
construction of the proposed Development phase would have an effect of negligible significance<br />
with regard to migration barriers.<br />
15.93. The proposed Development is within 1km of the River Usk SAC and is located within an existing<br />
built up area. The proposed Development at the Site is unlikely to directly impact the River Usk<br />
SAC during the demolition and construction phase given the separation of the River Usk SAC from<br />
the Site by infrastructure (A4042 Kingsway/Usk Way) and existing buildings. However there is<br />
potential that it could be affected by indirect effects of the Development during the demolition and<br />
construction phase including increased levels of dust, noise, vibration and light pollution. In addition<br />
the release of contaminants, sediments, fuels and chemicals into surface water as a result of<br />
demolition and construction activities could arise, which would ultimately enter the River Usk SAC.<br />
Thus, the proposed Development during the demolition and construction phase would have a<br />
temporary, minor adverse impact with regard to disturbance pressures.<br />
15.94. The drainage from the proposed Development would enter the main sewer rather than the River<br />
Usk SAC. Accordingly the effect on the River Usk SAC during the demolition and construction<br />
phase of the Development is considered to be of negligible significance with regard to diffuse<br />
pollution.<br />
15.95. It is considered that there would be no impacts on any other statutory or non-statutory sites during<br />
the demolition and construction phase, given the separation and distance of these sites from the<br />
application Site by surrounding urban development and infrastructure.<br />

Ecology_HMB_071211_001.docx
Habitats & Fauna<br />
Hard Standing<br />
15.96. Areas of hard standing are considered to have a negligible ecological value. As such, their<br />
removal during the demolition and construction phase would have an effect of negligible<br />
significance.<br />
Amenity Grassland<br />
15.97. The Development would result in the loss of amenity grassland within the Site boundary. This<br />
habitat is considered to have a negligible ecological value and therefore its removal during the<br />
demolition and construction phase would have an effect of negligible significance.<br />
Ornamental Planting<br />
15.98. Ornamental planting present within the Site boundary would be lost as part of the Development.<br />
These areas currently provide potential opportunities for foraging and commuting bats, along with<br />
foraging and nesting birds. However, the removal of these habitats would be unlikely to have an<br />
effect on bird and bat populations at a local level. Thus, the effect of the removal of this habitat<br />
during the construction phase of the Development would be considered a permanent, minor<br />
adverse impact within the Site only.<br />
Scattered Trees<br />
15.99. The proposed Development would result in the loss of all of the scattered trees present within the<br />
Site boundary. None of the trees on Site are considered to offer roosting opportunities for bats, but<br />
these areas do currently provide potential opportunities for foraging and commuting bats, along<br />
with foraging and nesting birds. However, the removal of these trees would be unlikely to have an<br />
effect on bird and bat populations at a local level. As such the effect of the removal of this habitat<br />
during the construction phase of the Development would be considered a permanent, minor<br />
adverse impact within the Site only.<br />
Buildings<br />
15.100. All buildings within the Site boundary would be demolished during the construction phase of the<br />
Development.<br />
15.101. Buildings B1, B2, B5 and B8 were originally noted as having low potential to support roosting bats.<br />
During the further bat survey, no evidence of bats emerging or entering the buildings was recorded.<br />
Therefore, from the results of these surveys it is considered that bats are not roosting at B1, B2, B5<br />
or B8. It is noted, however, given that bats are highly mobile species and given the potential<br />
roosting features present at B1, B2, B5 and B8, these buildings still have potential for roosting bats.<br />
15.102. No nesting birds were observed upon the buildings during the extended Phase 1 habitat survey.<br />
However there is limited potential for common bird species to utilise the buildings on Site during the<br />
active nest season (March to August inclusive).<br />
15.103. As such, it is considered that in the absence of mitigation the demolition of these structures during<br />
the construction phase would potentially be considered a permanent, minor adverse impact<br />
within the Site only.<br />
Bats<br />
15.104. The potential effects of the demolition of the buildings on Site to roosting bats are detailed above.<br />
Friars Walk, Newport<br />
Chapter 15: Ecology - Page 16<br />
Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.15 Ecology\Ch 15<br />
Ecology_HMB_071211_001.docx
15.105. The Site is considered to support sub-optimal foraging habitat as the level of foraging activity<br />
recorded at the Site was low. However, the Development will result in the loss of this sub-optimal<br />
habitat.<br />
15.106. During construction there may be disturbance (e.g. from increased light levels and noise) to low<br />
numbers of commuting and foraging bats within the Site.<br />
15.107. It is therefore considered that the impacts during the demolition and construction phase of the<br />
Development would result in a temporary and permanent, minor adverse impact within the Site<br />
only.<br />
Birds<br />
15.108. The removal of vegetation and buildings during the construction phase would cause the loss of<br />
potential nesting and foraging opportunities. If demolition or vegetation removal were to disturb an<br />
active nest during the bird breeding season (March to August inclusive) then this would be an<br />
offence under the WCA, 1981 (as amended) which protects nesting birds.<br />
15.109. The construction phase also has the potential to cause disturbance to breeding birds through<br />
indirect effects such as noise and dust from construction operations.<br />
15.110. The above effects during the construction phase would be unlikely to have an effect on bird<br />
population at a local level. However, in the absence of mitigation, these effects would be<br />
considered a permanent, minor adverse impact within the Site only.<br />
Invertebrates<br />
15.111. The ornamental planting and scattered trees within the Site are not considered to have potential to<br />
support any protected or notable species. However the habitats on Site are considered to be of<br />
value within the Site only for common invertebrate species. Therefore the loss of these habitats<br />
during the demolition and construction phase would be considered a permanent, minor adverse<br />
impact within the Site only.<br />
Completed Development & Operational Phase<br />
15.112. The Development has the potential to result in a number of ecological effects on completion of the<br />
Development and during the operational phase. Those relevant to the Site include:<br />
• Disturbance to the ecology of designated sites from the operation of the proposed Development<br />
and increased human activity;<br />
• Disturbance of birds and bats from the operation of the proposed Development and increased<br />
human activity.<br />
Designated Sites<br />
15.113. The impacts upon the River Usk SAC on completion of the Development and during the operational<br />
phase have been discussed in detail in Technical Appendix 15.3 and a summary has been<br />
provided below.<br />
15.114. The potential impacts upon the River Usk SAC on completion of the Development and during the<br />
operational phase are:<br />
• Disturbance pressures; and<br />
• Diffuse pollution.<br />
Friars Walk, Newport<br />
Chapter 15: Ecology - Page 17<br />

Ecology_HMB_071211_001.docx
15.115. The proposed Development would be located within an existing built up area and therefore there<br />
are no anticipated impacts from increased levels of noise, dust or lighting during the operational<br />
phase of the Development. In addition, the proposed Development is retail-led and therefore the<br />
demographic associated with this type of Development is unlikely to result in an increase in dog<br />
walkers which could potentially disturb otters using the River Usk SAC. As such, the proposed<br />
Development would have an effect of negligible significance with regard to disturbance pressures<br />
during the operational phase of the development.<br />
15.116. The drainage from the proposed development would enter the surface water sewer rather than the<br />
River Usk SAC. Consequently the effect on the River Usk SAC during the operational phase of<br />
the Development has been considered of negligible significance with regard to diffuse pollution.<br />
15.117. Owing to the current distances and intervening habitat between the Site and the remaining<br />
designated sites in the surrounding area, direct effects in relation to noise, dust, vibration, light or<br />
surface water run-off pollution on any of the designated sites from the proposed Development,<br />
once operational, would be unlikely. The likely effect on designated sites is therefore considered to<br />
be of negligible significance.<br />
Habitats & Fauna<br />
15.118. The habitats present within the Site are due to be lost. As such the potential impacts on these<br />
habitats during the operational phase would be negligible.<br />
Bats<br />
15.119. The completed Development could result in an increase in ambient light levels and as such may<br />
potentially impact on bats by discouraging them from moving through the area. Light pollution is<br />
known to discourage certain bat species from using flight lines and/or foraging grounds.<br />
15.120. Low activity of common pipistrelle bat has been recorded at the Site. Although this species is<br />
relatively light tolerant, it is considered that any increase in ambient light levels resulting from the<br />
proposed Development may impact upon bats commuting and foraging across the Site.<br />
15.121. As such, in the absence of mitigation, the operational phase of the proposed Development would<br />
likely give rise to a permanent, minor adverse impact within the Site only to bats.<br />
Birds<br />
15.122. The majority of the Site would be subject to a significant increase in disturbance from increased<br />
human activity associated with the proposed Development. Consequently, the potential effect on<br />
breeding birds during the operational phase, in the absence of mitigation, is considered to be<br />
permanent, minor adverse impact within the Site only.<br />
Mitigation Measures<br />
15.123. This section provides a summary of mitigation measures which would be implemented in order to:<br />
• Avoid, mitigate and compensate for the identified potential adverse effects;<br />
• Ensure that all works comply with relevant nature conservation legislation; and<br />
• Promote biodiversity on the Site.<br />
15.124. The mitigation proposals set out below describe mitigation measures which would be implemented<br />
during the demolition and construction and operational phases of the Development.<br />
Friars Walk, Newport<br />

Ecology_HMB_071211_001.docx
Demolition and Construction<br />
<strong>Environmental</strong> Management Plan<br />
15.125. An <strong>Environmental</strong> Management Plan (EMP) would ensure that appropriate environmental controls<br />
would be implemented during the construction phase. The EMP would be in accordance with<br />
relevant British Standards Best Practice Guidelines and would include ecological mitigation such<br />
as:<br />
• The control of lighting in order to ensure that there is minimal light spill on the habitats<br />
surrounding the Development and in particular the River Usk;<br />
• The use of British Standards best practice guidelines to reduce disturbance resulting from the<br />
arising of dust, noise and vibration during construction works;<br />
• The drainage of surface water from the Site would enter the main sewer, not the River Usk<br />
SAC.<br />
15.126. The EMP would be agreed with NCC, and specific levels set for noise, dust and vibration impacts<br />
during the commencement of demolition and construction works on the Site. The EMP would<br />
monitor these activities and update reports would be submitted to NCC on a regular basis. The<br />
EMP would also set measures on what to do if these levels are exceeded.<br />
Habitats & Fauna<br />
15.127. Demolition and site clearance works would be undertaken outside the main bird breeding season<br />
where practicable (i.e. only during September to February inclusive). If these works cannot be<br />
restricted to within this period, an Ecological Watching Brief would be maintained during the main<br />
bird breeding season to ensure that no nesting birds were adversely affected. This would involve<br />
checking all suitable habitats for nesting birds by a suitably qualified ecologist prior to the<br />
commencement of works.<br />
15.128. In the extremely unlikely event that bats are identified (given the current survey results) during the<br />
building demolition works, all works would cease and the County Ecologist and/or the Countryside<br />
Council for Wales would be contacted to find a suitable way forward.<br />
15.129. The proposed Development’s landscape strategy within the Site boundary would create new areas<br />
of shrub and tree planting along with small areas of amenity grassland. These areas would include<br />
native species and/or species of benefit to wildlife indicative of the local area. Once fully<br />
established, deciduous trees would provide nesting habitat for birds as well as habitat for<br />
invertebrates, and therefore foraging opportunities for birds, bats and other wildlife.<br />
Completed Development<br />
15.130. No impacts are anticipated upon the River Usk SAC on completion of or during the operational<br />
phase and therefore no mitigation is required.<br />
15.131. The lighting scheme for the proposed Development would take into consideration nocturnal species<br />
such as bats that are using the Site for commuting and foraging. Lighting would be selected to<br />
minimise potential impacts on ecological receptors.<br />
15.132. The new landscape planting would be subject to an appropriate management regime during the<br />
operational phase of the Development. This would aim to minimise human disturbance to the new<br />
habitat areas.<br />
Friars Walk, Newport<br />

Ecology_HMB_071211_001.docx
15.133. Bird boxes designed for appropriate bird target species within the UK BAP would be included at<br />
suitable locations within the proposed Development to provide enhanced bird breeding<br />
opportunities on the site.<br />
15.134. Bat bricks within new buildings along the River Usk facing side of the Development would be<br />
included within the proposed Development. These would be suitable for bat target species, which<br />
are included within UK BAP (species recorded in the data search) and for common pipistrelle as<br />
this species has been recorded within the application site during previous surveys.<br />
Residual Effects<br />
Demolition and Construction<br />
Designated Sites<br />
15.135. With the implementation of an EMP during the demolition and construction phase, the potential<br />
impacts to the River Usk SAC are considered to have a residual effect of negligible significance.<br />
15.136. The residual impacts upon the River Usk SAC during the demolition and construction phase have<br />
been discussed in detail in Technical Appendix 15.3.<br />
15.137. There are considered to be no likely effects on any other statutory or non-statutory sites owing to<br />
their sufficient separation from proposed Development. As such the residual impacts on statutory<br />
and non-statutory sites during the construction phase of the proposed Development are considered<br />
to be negligible.<br />
Habitats & Fauna<br />
Hard Standing<br />
15.138. The hard standing areas currently present at the Site are of negligible value. As such, no<br />
mitigation is required for their loss and consequently the resulting residual impacts would be<br />
negligible during the construction phase.<br />
Amenity Grassland<br />
15.139. The amenity grassland currently present at the Site is of negligible value. As such, no mitigation is<br />
required for its loss and consequently the resulting residual impacts would be negligible during the<br />
construction phase.<br />
Ornamental Planting<br />
15.140. The loss of ornamental planting would be compensated for by the proposed landscape strategy for<br />
the Site which includes replacement ornamental planting. The planting specification includes<br />
native seed and fruit bearing trees to optimise the value of the Site for wildlife. As such, it is<br />
considered that the mitigation proposed would result in a negligible residual impact to ornamental<br />
planting during the construction phase.<br />
Scattered Trees<br />
15.141. The loss of scattered trees would also be compensated for by the proposed landscape strategy for<br />
the Site which includes replacement tree planting. As such, it is considered that the mitigation<br />
proposed would result in a negligible residual impact to scattered trees during the construction<br />
phase.<br />

Ecology_HMB_071211_001.docx
Buildings<br />
15.142. As stated in the bird and bat section below, the demolition of the buildings on Site during the<br />
construction phase would result in a negligible residual impact.<br />
15.143. Bat bricks would be incorporated within new buildings along the River Usk facing side of the<br />
Development. This would provide Site enhancement in terms of the provision of bat roosting<br />
opportunities within the Site (see bat section below).<br />
Bats<br />
15.144. Bats are not considered to be roosting within any of the buildings or trees within the Site boundary<br />
and therefore their removal during the demolition and construction phase would result in a<br />
negligible residual impact. However, if there is a significant period of time between this report and<br />
the proposed demolition, the buildings may deteriorate in condition and should be subject to an<br />
update survey to determine if the rating of the buildings has changed.<br />
15.145. With the implementation of an EMP, the residual effects on bats in relation to lighting during the<br />
construction phase are considered to result in a negligible impact.<br />
15.146. The construction phase has the potential to directly impact upon bats through loss of foraging and<br />
commuting habitat. However, given that the habitat on Site is considered sub-optimal and only low<br />
numbers of bats were recorded, it is considered that proposed tree planting along the eastern Site<br />
boundary would replace the commuting and foraging habitat for bats. As such, it is considered that<br />
the mitigation proposed would result in a negligible residual impact to bat foraging and commuting<br />
habitat during the demolition and construction phase.<br />
Birds<br />
15.147. To prevent direct mortality of breeding birds, clearance of the vegetation and demolition of the<br />
buildings would be undertaken, as far as practically possible, outside of the breeding bird season<br />
(March to August inclusive). Should clearance or demolition be required within this period, a<br />
watching brief by a suitably qualified ecologist would be undertaken to ensure that no birds are<br />
breeding in the structures prior to removal. This would ensure that there would be no impacts to<br />
breeding birds. Effects would be negligible.<br />
15.148. The habitat loss for breeding birds would be compensated for through the landscaping scheme and<br />
provision of bird boxes in the completed Development.<br />
Invertebrates<br />
15.149. The vegetation currently present at the Site is of negligible value to notable or protected species of<br />
invertebrate, however these habitats are considered to provide opportunities for common<br />
invertebrate species. As such, no mitigation is required. It is therefore considered that this would<br />
result in a negligible effects within the Site only relation to invertebrates during the demolition<br />
and construction phase.<br />
Completed Development<br />
Designated Sites<br />
15.150. The residual effects upon the River Usk during the completed and operational phase of the<br />
Development have been discussed in detail in Appendix 15.3.<br />
Friars Walk, Newport<br />
Chapter 15: Ecology - Page 21<br />

Ecology_HMB_071211_001.docx
15.151. There are no anticipated impacts to the River Usk SAC or other surrounding designated sites<br />
during the completed and operational phase of the Development and as such the residual effect is<br />
considered to be of negligible significance.<br />
Habitats & Fauna<br />
Flora<br />
15.152. New habitats are proposed as part of the landscaping strategy. The implementation of an<br />
appropriate management regime of the new habitats would ensure their ecological value continues<br />
throughout the operational phase of the development. As such, it is considered that the residual<br />
impacts for the habitats at the Site would be negligible.<br />
Bats<br />
15.153. Through the incorporation of a number of measures, the lighting strategy would ensure that there is<br />
no additional significant effect on bats with regard to lighting. The provision of bat bricks would be<br />
included in the completed Development to create additional bat roosting opportunities on Site and<br />
therefore would result in a minor beneficial residual effects.<br />
Birds<br />
15.154. It is not predicted that there would be a significant increase in daytime human disturbance to cause<br />
an impact on breeding birds, owing to the current use of the Site being similar to the proposed<br />
Development. The provision of bird boxes would be included in the completed Development. As a<br />
result there would therefore be an operational effect of minor beneficial significance for birds as a<br />
result of the proposed Development.<br />
Summary and Conclusions<br />
15.155. A number of potential and residual effects have been identified for the demolition and construction<br />
phases of the Development and once the Development is completed and operational. There would<br />
be no negative residual effects to ecological receptors as a result of the proposed Development.<br />
These are summarised below in Table 15.4.<br />

16. Wind<br />
Introduction<br />
16.1. This Chapter assesses the potential effects of the proposed Development on the wind microclimate<br />
within and around the Site. The Chapter, and accompanying technical appendix (Technical<br />
Appendix 16.1), were written by RWDI with Waterman EED. New developments have the<br />
potential to change the way that wind blows through or around an area. New development also<br />
changes the way people move through or around an area. This assessment considers the<br />
potential wind microclimate in terms of its effect on pedestrian comfort.<br />
16.2. The wind microclimate is described in terms of the Lawson Comfort Criteria which are a familiar<br />
benchmark in the UK. Where appropriate, mitigation concepts are also described.<br />
Planning Policy Context<br />
National Planning Policy<br />
Planning Policy Wales 2011 1<br />
16.3. There is no specific guidance on potential wind microclimate issues in the Planning Policy Wales<br />
2011 or in the Technical Advice Notes (TAN).<br />
Regional & Local Planning Policy<br />
Adopted Newport Unitary Development Plan (UDP) 1996 - 2011 2<br />
16.4. The adopted Newport UDP contains no guidance on the potential influence of development on<br />
wind microclimate except The New City Centre Masterplan - Draft Supplementary Planning<br />
Guidance (SPG): Section 13 (page 24): General Design Guidelines: paragraph 13.5: ‘… Use street<br />
trees as design features and help reduce the effect of wind … ’<br />
Assessment Methodology and Significance Criteria<br />
Assessment Methodology<br />
16.5. Due to the height of the Development, it was considered that a desk-based assessment by an<br />
experienced, specialist wind engineering consultant would adequately identify, and quantify, the<br />
likely significant effects of the proposed Development on the wind microclimate.<br />
16.6. The assessment calculated the background wind climate for the Site and then considered the<br />
proposed building massing in the context of wind climate. The likely wind microclimate is classified<br />
in accordance with the widely accepted Lawson Comfort Criteria (see Table 16.1). The<br />
assessment considered both pedestrian comfort and the potential for strong winds. The main wind<br />
effects are expected within the Site and in the streets immediately surrounding the Site.<br />
Consequently, the key receptors would be pedestrians in these areas.<br />
16.7. The assessment does not account for landscaping or planting. This is a precautionary approach<br />
intended to present a worst-case assessment, as the presence of landscaping and/or planting<br />
would have a beneficial effect on wind microclimate at the Site. Where appropriate the beneficial<br />
effect of planting is addressed as a mitigation measure.<br />

Lawson Comfort Criteria<br />
16.8. The assessment of wind microclimate requires a ‘benchmark’ against which the conditions can be<br />
compared. The Lawson Comfort Criteria 3 have been established for over thirty years and have<br />
been widely used on building developments across the UK. The criteria take into account both the<br />
strength of the wind and the frequency with which certain wind speeds are exceeded.<br />
16.9. The Criteria (Table 16.1) set out six pedestrian activities and reflect the fact that less active pursuits<br />
require more benign wind conditions. The six categories are sitting, standing, entering/leaving a<br />
building, leisure walking, business walking and roadway/car park. For each of these categories, an<br />
upper threshold is defined, beyond which conditions are described as unacceptable for the stated<br />
activity. For example, if the wind speed exceeds Beaufort Force 4 (B4) for more than 4% of the<br />
time then the wind microclimate would be unsuitable for leisure walking.<br />
16.10. If conditions are below the threshold then they are described as tolerable (or suitable). It is<br />
expected that tolerable conditions would not affect the amenity of a location, whereas unacceptable<br />
wind conditions would lead to pedestrians not using an area for its intended purpose and<br />
complaints of wind nuisance. An unacceptable result implies that remedial action should be taken<br />
to mitigate wind conditions, or that the proposed pedestrian activity at that location should be redefined.<br />
16.11. The Criteria are derived for open air conditions where it is expected that pedestrians will be suitably<br />
dressed for the season. Table 16.2 presents the Beaufort (B) Land Scale for wind on land.<br />
Table 16.1: Lawson Comfort Criteria<br />
Pedestrian activity Threshold Description<br />
Car-park / Roadway B5 > 6%<br />
Business Walking B5 > 2% Purposeful walking<br />
Transient areas where people are not expected<br />
to linger<br />
Leisure Walking B4 > 4% Strolling<br />
Standing B3 > 6% Taxi drop-off / bus stop<br />
Entrance B3 > 6% Entering or exiting a building<br />
Sitting B3 > 1% Long-term sitting at a café or bench<br />

16.12. If wind speeds are sufficiently strong then they have the potential to hinder movement and in<br />
extreme cases blow pedestrians over. Lawson also recommended that strong winds should be<br />
reported separately from the comfort assessment. In this respect, if the wind speed exceeds<br />
Beaufort Force 6, 7, or 8 for more than 1 hour per annum, there may be a need for mitigation<br />
measures or a careful assessment of the expected use of that location, (e.g. whether it is it<br />
reasonable to expect elderly or very young pedestrians to be present at the location on the windiest<br />
day of the year).<br />
16.13. Experience has shown that when business walking and roadway conditions occur, the wind<br />
microclimate will also be characterised by occasional strong winds during the windiest season.<br />
Target / Desired Wind Microclimate<br />
16.14. The proposed Development comprises numerous retail units, a department store, cinema,<br />
restaurants and cafes and public open spaces. Typically, this would mean pedestrians would be<br />
strolling through the Development, walking in and out of the retail units or sitting in designated parts<br />
of the public spaces. In terms of the Lawson Comfort Criteria, this range of activities means that<br />
the wind microclimate would need to be suitable for a mix of leisure walking, standing/entering a<br />
building (standing/entrance) or sitting.<br />
16.15. The leisure walking and entrance classifications need to be met throughout the year, even during<br />
the windier winter season, because people will always need to walk around the Site and enter the<br />
buildings.<br />
16.16. The sitting classification would need to be met during the summer months when seating areas<br />
would be more frequently used. Note that achieving a sitting classification in the summer usually<br />
means that standing conditions would be achieved during the winter season when winds are<br />
stronger, unless there was some specific mitigation incorporated during the winter. The standing<br />
classification in the winter is usually acceptable and means that pedestrians would still be able to<br />
sit out on relatively calm days<br />
Seasonal Variation<br />
16.17. The technical assessment of wind microclimate was undertaken for the windiest season only.<br />
However, based on professional experience, the wind microclimate in the summer season would<br />
typically be 1 category calmer than that reported during the windiest season. For example, an area<br />
suitable for leisure walking in the windiest season would be suitable for standing in the summer<br />
because of the lighter winds that occur in the summer.<br />
Friars Walk, Newport<br />
Chapter 16: Wind - Page 3<br />
Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.16 Wind\Newport Wind_FINAL_001.docx
16.18. The assessment of outdoor amenity areas considers conditions in the summer because these<br />
areas are more likely to be frequently used in the summer. The stronger winds that occur in the<br />
winter mean that, unless there is some additional mitigation included during the winter season, an<br />
amenity area suitable for sitting in the summer will become suitable for standing in the winter.<br />
Significance Criteria<br />
16.19. The significance criteria do not incorporate an assessment of strong wind events and so, in line<br />
with the recommendations of Lawson, when strong winds are expected they are discussed and<br />
potential mitigation measures described separately. Strong winds tend to be associated with the<br />
business walking and roadway classifications. This means that areas where strong winds occur<br />
would usually require mitigation to enhance the wind microclimate in terms of both pedestrian<br />
comfort and the occurrence of occasional strong winds.<br />
16.20. The assessment of significance refers to the Lawson Comfort Criteria (Table 16.1). To determine<br />
the significance of the effect of the Development on the wind environment, comparison is made<br />
between the expected wind conditions and the desired pedestrian use of the Site. This<br />
assessment of significance takes into consideration the change in pedestrian use of the Site which<br />
typically accompanies development and is considered a more meaningful assessment than a direct<br />
comparison with the wind microclimate at the existing site.<br />
16.21. Effects can be beneficial, adverse or negligible and beneficial and adverse effects are classified as<br />
either of minor, moderate or major significance. A beneficial effect would imply that the wind<br />
microclimate was calmer than required for a specified pedestrian activity whereas an adverse effect<br />
implies that conditions would be windier than desired. Adverse effects would usually require<br />
mitigation. The following scale is used to define the significance criteria:<br />
• Substantial adverse: 3 categories windier than desired<br />
• Moderate adverse: 2 categories windier than desired<br />
• Minor adverse: 1 category windier than desired.<br />
• Negligible: wind microclimate equivalent to that desired<br />
• Minor beneficial: 1 category calmer than desired<br />
• Moderate beneficial: 2 categories calmer than desired<br />
• Substantial beneficial: 3 categories calmer than desired.<br />
16.22. As an example, if the wind microclimate in a part of the development was suitable for leisure<br />
walking, this would imply a minor adverse effect outside an entrance, a negligible effect if on a<br />
pedestrian thoroughfare or a major beneficial effect if in the middle of a road.<br />
Baseline Conditions<br />
Wind Climate<br />
16.23. The Meteorological (Met) Office supply joint frequency tables of wind speeds divided into ranges of<br />
the Beaufort (B) scale, and direction on a monthly and annual basis for 30 degree (°) sectors<br />
around the compass. These data have been corrected to standard conditions of 10 metres (m)<br />
above open flat level country terrain at sea level and indicate the directionality of the background<br />
wind climate for the region. The data for Rhoose Airport are presented for all seasons in Figure<br />
16.1. The wind rose shows a dominant westerly wind throughout the year but with a secondary<br />
wind from 60.<br />

‘Background Windiness’ at the Site<br />
16.24. The terrain roughness is unique to a site and is important because it influences the wind<br />
characteristics in each wind direction. Table 16.3 presents the ‘mean factors’ for the Site where the<br />
mean factor represents the ratio of wind speed on Site, at the stated reference height, as a fraction<br />
of the wind speed in open, flat countryside at a height of 10m. The mean factors for the Site at 2m<br />
ranged from 0.44 to 0.61 and the higher mean factors, which denote higher wind speeds, are<br />
attributed to the open spaces found to the north, east and southeast of the Site.<br />
16.25. Combining the mean factors with the meteorological data enables the ‘background windiness’ of<br />
the Site to be calculated at 2m above ground level. For the proposed Development, conditions<br />
would be suitable for standing/entrance use during the windiest season.<br />

Wind Microclimate at the Existing Site<br />
16.26. The existing buildings on the Site are low-rise with a similar profile to the majority of buildings in the<br />
immediate vicinity.<br />
16.27. The existing office building (Chartist Tower), on the west side of Upper Dock Street, is the tallest<br />
building in the area and is directly exposed to wind from all directions. However, because it is<br />
centrally located within the plot, the roofs of the buildings which front onto Commercial Street, Corn<br />
Street, Upper Dock Street and Austin Friars, act as a podium and prevent downdraughts from the<br />
tower directly affecting street level.<br />
16.28. Consequently, the wind speeds in the streets within and around the existing Site are expected to<br />
be suitable for either sitting or standing during the windiest season and predominantly suitable for<br />
sitting in the summer when winds are lighter. Strong winds, in excess of Beaufort Force 6, are not<br />
expected to occur because of the sitting and standing conditions expected around the existing Site.<br />
Potential Effects<br />
Demolition and Construction<br />
16.29. During demolition the Site will be progressively cleared which will increase the exposure of the<br />
Upper Dock Street buildings to winds from the easterly sector. The Site hoarding will provide<br />
localised shelter downwind of the hoarding. Consequently, Upper Dock Street and the streets<br />
which connect with Commercial Street, e.g. Austin Friars, are expected to become windier and<br />
suitable for standing in the windiest season. These potential effects are anticipated to be shortterm,<br />
temporary, local and of negligible significance at the entrances and minor beneficial<br />
significance on the streets.<br />
16.30. As construction continues the wind microclimate will progressively adjust to that described below<br />
for the completed Development.<br />
Friars Walk, Newport<br />
Chapter 16: Wind - Page 5<br />
Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.16 Wind\Newport Wind_FINAL_001.docx
Completed Development<br />
16.31. All the effects described below are considered to be long-term, permanent and local to the Site<br />
and its immediate environs.<br />
Commercial Street<br />
16.32. Commercial Street is a main retail street in the City and because of the ‘buffer’ of existing buildings<br />
that line the east side of Commercial Street, the wind microclimate on Commercial Street is<br />
expected to be unchanged by the proposed Development. The wind microclimate along<br />
Commercial Street is classified as suitable for standing/entrance use during the windiest season,<br />
an effect of minor beneficial significance on a pedestrian thoroughfare.<br />
Upper Dock Street<br />
16.33. Upper Dock Street is nominally aligned north to south. The height-to-width ratio of the street varies<br />
along its length but is in the of order 1.0. This means that the wind from the south westerly and<br />
north easterly sectors would tend to blow across Upper Dock Street with relatively little penetration<br />
down to pavement level.<br />
16.34. Wind from the east and southeast would be able to blow into John Frost Square and then along<br />
Upper Dock Street or Friars Lane, but the winds from these directions are neither frequent nor<br />
strong. The enclosure of the north end of Upper dock Street, adjacent to the existing tower, is<br />
expected to create leisure walking conditions in central parts of this street.<br />
16.35. The wind microclimate along Upper Dock Street is therefore expected to be suitable for<br />
standing/entrance use from John Frost Square to Austin Friars, a minor beneficial effect on a<br />
pedestrian thoroughfare and leisure walking from Austin Friars to Corn Street, a negligible effect.<br />
Friars Walk<br />
16.36. The main north-south part of Friars Walk would be sheltered from both the westerly and easterly<br />
prevailing winds because of its alignment and the roof canopy. The width of John Frost Square<br />
would be approximately twice the height of either the Cinema or the Friars Walk buildings.<br />
Consequently, when the wind blows from the south easterly quadrant, there would be intermittent<br />
gusting down beneath the canopy and into the southern end of Friars Walk. However, as shown in<br />
Figure 16.1, wind from this direction is neither strong nor frequent.<br />
16.37. The Upper Dock Street entrance to Friars Walk is aligned with Austin Friars. The existing<br />
buildings, on the west side of Commercial Street, would shelter Austin Friars from westerly winds,<br />
but channelling of roof-top winds towards the Upper Dock Street entry to Friars Walk is possible.<br />
The roof-top winds are expected to blow into Friars Walk at high level and so the upper level<br />
walkways would be windier than the ground level areas.<br />
16.38. At the upper level, the southern end of Friars Walk is anticipated to be suitable for leisure walking<br />
during the windiest season because of wind intermittently blowing in from the south easterly sector.<br />
As a pedestrian thoroughfare, this would represent negligible significance.<br />
16.39. The wind microclimate along the remaining parts of Friars Walk is expected to be suitable for<br />
standing at ground level and at the upper level during the windiest season. This would represent a<br />
minor beneficial significance.<br />

Z:\Projects\E12300\100\Reports\Working Drafts\ES\<strong>Volume</strong> 1 - ES <strong>Main</strong> Document\Ch.16 Wind\Newport Wind_FINAL_001.docx
Corn Street<br />
16.40. The wind microclimate on Corn Street is expected to be suitable for standing/entrance use apart<br />
from the east end of the street which would be exposed to wind from the easterly sector<br />
channelling towards this corner. On the basis that Corn Street is predominantly a pedestrian<br />
thoroughfare, the significance of these effects is minor beneficial or negligible.<br />
John Frost Square & Usk Plaza<br />
16.41. As public amenity space is primarily used during the summer months, sitting conditions should be<br />
targeted during the summer. Unless there is specific mitigation during the winter, the stronger<br />
winds that occur would usually mean that these areas would be classified as suitable for standing<br />
in the winter.<br />
16.42. As shown on Figure 16.2, the curved, recessed zone, on the west side of the Usk Plaza would be<br />
sheltered from westerly winds and is expected to be suitable for sitting. Eastern areas of the Usk<br />
Plaza are more open and are therefore expected to be suitable for standing during the windiest<br />
season. However, it is expected that the Usk Plaza will be suitable for sitting in the summer. The<br />
significance of these effects is therefore negligible when assessed in terms of the desired<br />
pedestrian use of the Plaza in the summer.<br />
16.43. As shown in Figure 16.2, John Frost Square is anticipated to be suitable for standing in all parts of<br />
the Square during the windiest season. However, westerly winds and easterly winds are expected<br />
to blow through this space so that in the summer the plaza is expected to be suitable for sitting<br />
around its periphery and standing in central parts of the Square (this central area is denoted by the<br />
dashed line in Figure 16.2). The significance of these effects in the summer is negligible because<br />
the mix of sitting and standing conditions is considered suitable for the desired pedestrian use of<br />
the plaza.<br />
Bus Station<br />
16.44. The bus station would be at the lowest elevation on the Site and would be sheltered from the<br />
prevailing westerly winds by the buildings of the Friars Walk Development. Wind from the easterly<br />
quadrant would be channelled towards the bus station making the two corners of the buildings that<br />
surround the bus station relatively windy. However, the overall conditions are expected to be<br />
suitable for standing with leisure walking classifications at the external corners.<br />
16.45. The significance of these conditions is negligible at the windier corners, which people will walk<br />
past and negligible in the main bus station on the basis that is a large waiting area.<br />
Kingsway West<br />
16.46. The Kingsway West elevation would be sheltered from prevailing westerly winds and is also at a<br />
low level (+9.0m). The majority of this elevation would be relatively insensitive in terms of<br />
pedestrian use because it is a thoroughfare adjacent to a busy road. The cinema would be located<br />
at the southern end of the Kingsway West elevation and there is a taxi pick-up/drop-off point<br />
proposed where pedestrians would be expected to wait. This elevation of the Development would<br />
be sheltered from westerly winds, a significant factor in creating relatively calm conditions.<br />
16.47. The northeast corner of the cinema block is expected to be suitable for leisure walking because of<br />
the potential acceleration of wind around this corner. Other areas are expected to be suitable for<br />
standing during the windiest season. The conditions are therefore suitable for the desired<br />
pedestrian activities and resulting in an effect of negligible significance.<br />

Mitigation<br />
Demolition and Construction<br />
16.48. There are no adverse effects identified during demolition and construction and so no mitigation is<br />
required.<br />
Completed Development<br />
16.49. There are no adverse effects identified as a result of the completed Development and so no<br />
mitigation is required.<br />
Residual Effects<br />
Demolition and Construction<br />
16.50. The residual effects during demolition and construction are, at worst, negligible, because the wind<br />
microclimate is anticipated to be suitable for the desired pedestrian use of the Site and<br />
surroundings.<br />
Completed Development<br />
16.51. There are no recommendations for mitigation at the completed Development and so the residual<br />
effects are the same as the potential effects that is negligible to minor beneficial during the windiest<br />
months and negligible to moderate beneficial in the summer months.<br />
Summary and Conclusion<br />
16.52. The potential and residual effects are summarised in Table 16.4 below. All potential effects for the<br />
completed Development are considered to be long-term, permanent and local to the Site and its<br />

18. Summary of Likely Residual Effects<br />
Introduction<br />
18.1. The likely residual effects of the Development, following implementation of the proposed<br />
mitigation measures, are assessed in the preceding Chapters of this <strong>Environmental</strong> <strong>Statement</strong>.<br />
Each Chapter contains a detailed assessment of the residual effects. However, for ease of<br />
reference a summary of the main effects of the Development have been set out in Table 18.1.<br />
The significance criteria used are defined in Chapter 2: EIA Methodology, and where required this<br />
is supplemented in the relevant technical Chapter.<br />
18.2. This EIA was undertaken in parallel with the design process. As a consequence, many measures<br />
to mitigate potential adverse environmental effects are incorporated into the scheme design in<br />
order to avoid, reduce or offset such effects.<br />
18.3. With respect to the management of the construction process, it is intended that a Construction<br />
<strong>Environmental</strong> Management Plan (CEMP), as outlined in Chapter 6: Development Programme,<br />
Demolition and Construction, would be prepared and implemented. This is an established<br />
method of controlling and minimising environmental effects arising from demolition and<br />
construction activities, and would serve to reduce adverse environmental effects such as noise<br />
and vibration, dust, and the risk of surface and groundwater pollution. The CEMP would also<br />
control and manage hours of work, traffic routing and access, the protection of archaeological<br />
resources and protected species, and the generation and disposal of waste. In addition, the<br />
CEMP would include monitoring and reporting requirements. It is anticipated that certain aspects<br />
of the CEMP and other mitigation measures identified would be secured by appropriate planning<br />
obligations or conditions.<br />
