Attachment 5 - Traffic Impact Assessment Final PTT · 132005.638.06

Executive summary
Review of the current NRRF operations across the transfer area, RRA1 and WMC area has been
undertaken by Aurecon to develop an integrated upgrade to these areas that will improve diversion from
landfill. Primary objectives of the masterplan include improved customer and operator safety, optimised
efficiency, reduced delay and queuing on site, and reduced capital and operational costs. Concept design
drawings and design requirements have been provided to inform and support the detailed design phase of
this project. The masterplan design includes layout, surface water and traffic design. It is estimated that the
masterplan updates will cost approximately $37 million with 30% contingency applied. Key changes to the
layout of the NRRF proposed as part of this masterplan include:
◼   Combination of transfer bays and bulk bay into a single transfer area for all vehicles
    − Transfer bays provided for both small and rigid vehicles, and vehicles towing trailer
    − Bulk tipping floor for larger vehicles including compactor trucks and articulated vehicles
◼   Provision of covered area for secondary sorting of transfer waste
◼   Reconfiguration of internal roadways for separation of operational traffic and reduced interactions
    − Roundabout incorporated at entry access
    − Culvert crossing of the main drain to shorten route to RRA1
    − Weighbridge bypass for operational and contractor vehicles
◼   Additional dual Weighbridge (incoming and outgoing) to reduce queuing and improve traffic flow
◼   Consolidation of areas for free-of-charge disposal prior to transfer to support increased landfill diversion,
    reduce customer internal site movements, and differential pricing
    − Separated disposal and operational access for collection of items, and processing by NSC
◼   Expansion and reconfiguration of the WMC Area
◼   Replacement of the HES basin and bio-basin, with an integrated basin for water treatment, addition of a
    small basin to treat surface flow from timber processing areas and landfill capped area
    − Surface topography, open drainage and diversion bunds to support overland flow through site.
