How does our plan manage flooding?

The precinct currently includes land that is subject to inundation in a 1% Annual Exceedance Probability (AEP) event.

We have undertaken extensive flood modelling to determine the impacts of 1% AEP flooding, under current and future climate changes, and to ensure no increase in flooding downstream or offsite is created by the precinct.

In our plan, we have included these requirements to manage stormwater and riverine flooding:

• No new development in areas that have a high flood hazard.
• Enhancing and protecting the Broken River floodplain to provide additional flood protection.
• Designed passage and temporary storage of floodwaters for the 1 in 100 AEP including climate change.
• An urban standard stormwater drainage system.
• Specific requirements for property and lot heights, flow levels and local roads.

Flood modelling scenario planned for in our precinct, is greater than the most recent and October 2022 flood event.
