South Creek rises near Narellan in the south west and, with its tributaries, meanders 70 kilometres north until meeting the Hawkesbury River, near Windsor.
The South Creek Corridor forms the spine of the city, which is expected to house some 1.5 million people by 2056.
“Development along the spine and its tributaries will re-imagine liveability and sustainability,” according to the NSW government.
“South Creek catchment and its tributaries will be an environmental asset [and] shape the aerotropolis’s environment and the lifestyles on offer.”
The tree canopy will be increased to mitigate the heat effects; the emerging city can be 10 to15 degrees warmer than the Sydney CBD, and susceptible to extreme heat
“The precinct will include [also] open spaces, regional parks, recreation facilities, restaurants, cafes, pedestrian and cycle connectivity,” the Western Sydney Aerotropolis Planning Package said.
Residential densities of 45 to 55 dwellings per hectare would frame the South Creek Corridor, increasing to 65 to 80 dwellings per hectare in locations serviced by high frequency public transport.
The 1950-hectare precinct is among the first parcels of land to be rezoned for the Western Sydney Aerotropolis under a specially created environmental planning policy set to be completed by mid-2020.
The aerotropolis has been divided into 10 precincts, with three initial precincts— the Aerotropolis Core, Northern Gateway and South Creek—identified by the government as offering the greatest growth potential.
The green corridor would be complemented by the Western Economic Corridor, the backbone of which is the first stage of the North-South Rail Link from St Marys to the airport and the aerotropolis; the service would be extended southwards at a later date.
