The construction activities required at each work site are described in Table 3-3 to
Table 3-7 with a summary provided in Table 3-2. They include:
The installation of equipment to support temporary traffic management controls
The installation of equipment to support temporary footpath restrictions
Major equipment relocation
Tree removal and punning
Ground excavation work associated with utility adjustments, drainage
modifications and general signal, lighting pole and traffic signal relocations
Regarding and resurfacing the road
Adjustments to the footpaths, kerbs and intersections requiring cutting, grinding
and sawing.
Streetscape character would also be impacted by general construction activities, dust
generation, amenity affects (including noise and vibration impacts), loading and
unloading activities, the presence of construction equipment, and the bollards,
fencing and hoardings that would be used to demark all active working areas.
The above factors were considered in determining the proposal’s landscape and
streetscape impacts. Whilst the construction impacts would depend on the activities
taking place in a given location and the duration of the activities, it was broadly
assessed that the more major supporting work and traffic capacity improvements
(refer to Table 3-2) would require a greater level of construction activity in a given
location for a longer period of time. On this basis the following impact magnitude
ratings were used to assess the impact on landscape and streetscape character:
Intersection reconfiguration and geometry modifications: low-high
Kerb extension alterations: low-high
Footpath width alterations: low-high
Turning restrictions and provisions: low
Kerbside allocation modifications: low
Lane arrangements: low
Supporting work:
- Major equipment relocation: low-moderate
- Tree pruning or removal: low-moderate
- Bus lane marking alterations or instalment: low
- Road regrading and resurfacing: low-moderate
- Traffic signal and lighting pole works: low
- Surface drainage modification and relocation: low
- Bus shelter relocation: low
- Utility works: low-moderate.
The above ratings were applied to the construction activity taking place in each
location as described in Table 3-3 to Table 3-7 and assessed against the sensitivity
of the landscape and streetscape to change as set out in Table 6-39. The
assessment considered the highest impact magnitude rating occurring within a given
work site and applied it to the whole work site. It did not differentiate between
variability in the type and scale of activity within a work site.
Table 6-43 provides a summary of the construction impacts on the landscape and
streetscape character of the study area.
