Wianamatta South Creek Flood Study 2020

Council is exhibiting the Draft Wianamatta South Creek Flood Study and welcomes your feedback.

As part of planning for the Western Sydney Aerotropolis, the NSW Government is undertaking a study to identify potential impacts on flood behaviour resulting from proposed future development across the broader South Creek Catchment.

The study aims to investigate management measures to limit the cumulative impacts on flood behaviour and existing development.

The first stage of this study is an opportunity for Council to update and align its flood mapping to the current information available for this catchment.

The updated flood information will replace the current (2004) study and prevents duplication from using different sets of flood related information to predict flood behaviour for the same catchment.

While the flood extents resulting from the new study are generally consistent with the current flood maps, some variations have been noted around a small number of the flood fringe areas. However, any variations between the current and the new flood maps are minor and mostly attributable to higher levels of accuracy in the topographical data that has been used for the new study.

Residents who live in the South Creek Catchment Area (Rossmore, Kemps Creek, Austral or Badgerys Creek) and are affected by flooding from South Creek are invited to register to attend a face-to-face meeting to find out how the flood-related changes affect your property.

Register by emailing: with your name, contact details, preferred meeting time and specify what you would like to discuss by 5pm, Friday 30 October 2020. Meetings will be held in accordance with a COVID Safe Engagement Plan. All attendees must wear a face mask.
