Wianamatta South Creek Catchment Flood Study - Existing Conditions (Rev I)

The Wianamatta South Creek Catchment Flood Study - Existing Conditions (2022) report updates and extends a previous study prepared for Penrith City Council in association with Liverpool, Blacktown and Fairfield City Councils (2015). It uses contemporary topography and more refined modelling to provide up-to-date flood information for the South Creek Catchment between Bringelly Road and Richmond Road, including tributaries such as Kemps, Bonds, Badgerys, Cosgroves and Oaky creeks. The study also includes a climate change sensitivity.
