How will flooding be managed and mitigated?

The precinct currently includes land that is subject to inundation in a 1% Annual Exceedance Probability (AEP) event, also known as a 1-in-100 year event.

We have undertaken extensive flood modelling to determine the impacts of 1% AEP flooding event. In consultation with the City of Ballarat and Glenelg Hopkins Catchment Management Authority (GHCMA), the PSP has been developed to ensure no increase in flooding offsite is created by the precinct and to ensure new homes in the precinct are also protected.

The PSP addresses stormwater and flooding impacts by:

• Not locating new residential use or schools in areas that have a high flood hazard.
• An urban standard drainage system, including requiring new retarding basins in strategic locations in the precinct.
• Enhancing and protecting the Burrumbeet Creek to provide additional flood protection.
• Encourage Water Sensitive Urban Design and Integrated Water Management strategies to enhance catchment resilience.
