Wollondilly Shire Wide Flood Study – Council seeks local knowledge and personal experiences

Wollondilly Shire Council is seeking feedback from the community for a Shire Wide Flood Study that ranges from Silverdale to Yanderra and Nattai to Appin, in an effort to better understand flooding across the Wollondilly Local Government Area.

This project builds on the recently adopted Stonequarry Creek Flood Plan and the range of actions already delivered and now underway to help address flooding for Picton.

Council has engaged consultants Advisian to carry out the Flood Study, which will involve detailed flood modelling using latest topographic data and modelling techniques.

Flood mapping will be produced to identify existing flood risks and inform future floodplain management. The Flood Study will cover the eastern portion of Wollondilly Shire comprising 700 km2.

Wollondilly Mayor Matthew Deeth said, “This is a new project to help us learn about flooding in the parts of the Shire where we don't have great information at present”.

“We’ve made great progress in Picton and now have an adopted plan underway to minimise flooding from Stonequarry Creek’.

“The new flood study will assist in managing flood risk for the community across the whole Shire, so I would encourage residents to get involved in the consultation process.”

“The information provided to Council will contribute to the flood study and how we approach future storm and flood events,” he said.

Local knowledge and personal experiences are valuable in helping to identify local flooding issues. Council is seeking input from the community including floodmarks in particular areas, such as the height that floodwaters reached against a tree or building during a particular flood event.

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. Thankyou to everyone who provided input on our Stonequarry Creek Floodplain Risk Management Study and Plan. This Shire Wide study follows on from that.
