New study maps future flood risk

A new flood study will help residents and emergency services better understand the flood risks across the City of Parramatta and keep them safe.

The draft study uses advanced technology to model flooding risk from the river and overland flows and is the most significant update to the City’s flood data in 20 years.

City of Parramatta chief executive Gail Connolly PSM said it was critical residents understood their flood risk and could prepare for it.

“We are a river city and subject to flooding – and not just from the river but from run-off after heavy storms,” Ms Connolly said.

“We hope we never see the major floods this study considers but it’s important to still be prepared for the worst-case scenario so we can help keep our community safe.

“These new maps will help Council investigate methods to reduce flood risk and arm residents and emergency services with the best possible information to prepare for flooding.”

The draft study maps flood risk across large parts of the Local Government Area and identifies flood risk on more than 12,000 land parcels ranging from depths of 300mm to more than four metres. The remaining area of the LGA will be mapped through separate studies.

Residents are invited to review the draft study and share their feedback by booking a one-on-one call or face-to-face meeting with the City’s flood team or by making a written submission.
