PHASE 2: ANALYSIS BADGERYS CREEK WESTERN SYDNEY AIRPORT
WESTERN SYDNEY INFRASTRUCTURE PLAN Rail services are expected to be required as part of a multi-modal transport solution by the time the Airport reaches 30 MAP, estimated to be in the mid-2040s.
The main access to the Airport Site will be from the north via a link to the M12 Motorway, which is planned to be completed and operational prior to the commencement of airport operations. The M12 is expected to predominantly run parallel with Elizabeth Drive. Access to the Airport Site from the southwest will be via The Northern Road, which will be relocated off-site from its current alignment, upgraded and completed before the start of airport operations. This access point is anticipated to provide secure access to commercial and operational support areas, including freight and maintenance in the long term. This access road is expected to consist of a corridor approximately 50 m wide, allowing four trafficable lanes.
There will be no immeadiate railway access to the airport although it is acknowledged that railway infrastructure will be necessary in the future. It is definitely something that needs to be incorporated into the infrastructure plan as roads are not a long term reliable solution. Rail will provide a reliable mode of transport that is affordable to everyone and will allow greater access to the Western Sydney Airport.

HYDROLOGY: RE-DEFINING SUBCATCHMENT BOUNDARIES Changes to catchments and impervious areas have the potential to impact indirectly on the channel morphology of watercourses downstream of the airport site. In particular, catchment changes that result in increasing downstream flow durations and/or increased hydraulic shear stress can exacerbate erosion of the bed and banks of watercourse channels downstream of the airport site. The study finds that construction of the airport would result in a major modification of the site in terms of land use characteristics and surface water runoff generated. It would also result in removal of a large number of watercourses and farm dams. The subcatchment areas will be redefined to accomodate the newly created topogrophy. This will be down through the use of man made channels, underground water pipes and a number of pits located strategically around the airport site.
EXISTING BOUNDARIES
LONG-TERM BOUNDARIES
FLOOD EVENTS A number of the flood-affected rural residential lots outside the airport site are located in Bringelly in the area bounded by the airport site, The Northern Road and Badgerys Creek Road. Based on the available imagery, though a number of lots would experience some inundation in a 100 year ARI event, most existing dwellings in this area remain outside the flood extent. There are a number of existing dwellings located within the flood extent or in close proximity to the flood extent clustered on Badgerys Creek upstream of the site. Two dwellings in close proximity to the flood extent were also identified downstream of the airport site on Cosgroves Creek. On the eastern bank of Badgerys Creek are a number of flood affected lots, though the existing dwellings are located beyond the 100 year flood extent. This includes dwellings on the parcel of land located on the eastern side of Badgerys Creek that may in future become part of the airport site which are not within the 100 year flood extent and are therefore not marked on the map.
