Wollondilly Shire Wide Flood Study

It’s more important than ever to be aware of flood risks where you live.

Wollondilly Council’s draft Shire Wide Flood Study – is now on Public Exhibition and we are seeking community feedback until 8 June 2022.

The Study ranges from Warragamba and Silverdale to Yanderra, and from Nattai to Appin, and uses the latest topographic data and modelling techniques as well as local knowledge, in an effort to better understand the nature and extent of flooding across Wollondilly Shire.

In the previous round of consultation, we asked the community to share their knowledge of flooding history and rainfall amounts in Wollondilly – thank you to everyone who contributed. That input has helped inform the detailed flood modelling to produce flood mapping that identifies existing flood risk, and will inform future floodplain management.

Now we would like to verify that the flood mapping and information in the Flood Study is consistent with your observations and experience. You can view the Study itself as well as using the interactive map.

Council is undertaking this Flood Study under the guidance of the NSW Flood Prone Land Policy, which requires Council to manage the existing flood risk with consideration to the social, economic and environmental impacts of flooding for the short, medium and long term. Council has engaged consultants Advisian to carry out the Flood Study.

Thankyou to everyone who provided input regarding Stonequarry Creek. The new Shire Wide study builds on the adopted Stonequarry Creek Floodplain Risk Management Plan and the range of actions already delivered and now underway to help address flooding for Picton.
