Warrawee Substation - Review of Environmental Factors

Assessment of the environmental impacts and risksIssueLight spillUtilitiesControl measuresAccess along the pedestrian path adjacent to the corridor to bemaintained at all times during construction.A designated heavy vehicle route would be identified within thetraffic management plan. Heavy vehicles accessing the sitewould be required to use this route.Vehicle movements to and from the site to be minimised duringschool start and end times.Liaison with Ku-ring-gai Council is required to confirm thedesign, location and approval requirements for the proposedsite accesses.Signage and traffic control devices would be installed to alertmotorists and pedestrians to changes to local traffic conditionsduring the construction period.Oversized vehicle movements would be discussed with RMSand NSW Police prior to them occurring.Works would be undertaken during standard daytimeconstruction hours where possible to avoid the use of lights.Use of lighting during night-time works would take intoconsideration the light spill impacts on surrounding residentialdwellings. All lighting for the proposal would be designed andinstalled in accordance with the requirements of AS 1158Road Lighting and AS 4282 Control of the Obtrusive Effects ofOutdoor Lighting to minimise light spill onto adjacentresidences, and would include the use of baffles around lightfixtures where possible. Only those work areas being usedwould be lit at any time.The proposal would be minimise light spill from the site inaccordance with relevant codes and Australian Standards.Protection of the overhead wires on Brentwood Avenue wouldbe required when tall vehicles are required to access the site.Service searches (such as dial before you dig and an onsitesearch with a services locator) would be undertaken prior toundertaking activities that have the potential to impact utilityservices. If the results of the searches indicate that servicesare likely to be affected, relevant service providers would beconsulted to discuss potential impacts and develop measuresto minimise impacts, including the need for service relocationor temporary connections.Warrawee Substation Project/Review of Environmental FactorsPage 58 of 64
