22Government under Section 28 of the Planning and Development Act 2000,have underlined the importance of compact and sequential development ofurban areas with a focus on town and city centre locations for major retailingand higher residential densities.Box 3.2 - Justification TestPlanning GuidelinesWhere a planning authority is considering the future development of areas at ahigh or moderate probability of flooding that would include types of developmentthat are inappropriate under the screening process set out in paragraphs 3.6 and3.7, either in a development plan or development management context, the planningauthority must be satisfied that the development is necessary on the basis of allof the following criteria:PART 11. The area is within or adjoining the centre* of a city or town designated forgrowth in key policy documents such as the National Development Plan,the National Spatial Strategy, any Regional Planning Guidelines in force,planning guidelines/directives under Sections 28/29 of the Planning andDevelopment Act 2000 and/or an operative City/County development planwhich has been adopted taking adequate account of these guidelines.2. The area comprises significant previously developed and/or underutilisedlands within the urban envelope.3. Development of the area is essential to facilitate regeneration or town andcity centre expansion, as demonstrated in city and county development plansthat have been assessed in accordance with these guidelines.4. Strategic Environmental Assessment has been undertaken, where applicable,taking full account of flood risk.5. There are no reasonable and available alternative development areas or sitesthat meet the wider strategic policy requirements as outlined at 1 above,within low or lower flood probability areas.* See Glossary for definitions of “town centre” and “edge of town centre”.
PART 2If the requirements of Part 1 are satisfied, then the following additional detailedcriterion should also be met.23The development has been the subject of a sufficiently detailed flood risk assessment,as appropriate to the nature and scale of the development, and the potential riskthat may arise, which demonstrates that:(a)(b)the development will not increase flood risk elsewhere and, if possible, willreduce overall flood risk;the development proposal includes measures to minimise flood risk to people,property and the economy and the environment as far as reasonably possibleand to ensure that residual risks to the area and/or development can bemanaged to an acceptable level as regards the adequacy of existing floodprotection measures or the design, implementation and funding of any futureflood risk management measures.(See Appendix A)Note: In the event that land is zoned without the benefit of these guidelines,please refer to Para 5.23.3.10 It is clear that a balance needs to be achieved between accommodatingappropriate growth as outlined above and the avoidance of flood risk. TheJustification Test has been designed to rigorously assess the appropriatenessor otherwise of particular developments that, for the reasons outlined above,are being considered in areas of moderate or higher flood risk.3.11 Development that is inappropriate under the screening process set out insection 3.6 and that does not meet the criteria of the Justification Test shouldnot be considered at development plan stage nor through the developmentmanagement process.How does the Justification Test work?3.12 The application of the Justification Test within the sequential approach essentiallyrequires the justification of development in existing urban areas as outlinedabove, where expansion or consolidation in flood risk areas is being considered.The development must be consistent with the proper planning and sustainabledevelopment of an area and must demonstrate that it will not be subject toan unacceptable level of flood risk. The operation of the Justification Test isa key step within the sequential approach and is applied to test both zoningdecisions and development applications. It should be noted that detailedstudies to support Part 2 of the Justification Test should only be commissioned,after the criteria under Part 1 have been met (See Appendix A, Section 2).Planning Guidelines
