How does our plan manage flooding?

The precinct currently includes land that is subject to inundation in a 1% Annual Exceedance Probability (AEP) event. Climate change has been factored into the 1 in 100 AEP flood estimation in accordance with the BoM Intensity-Frequency-Duration 2016.

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.

Flooding in the precinct is associated with Russell Creek, a tributary of the Merri River. Key flood management features in the plan include:

• No new development in high flood hazard areas

• Protecting and enhancing the Russell Creek floodplain

• Temporary storage of floodwaters via drainage basins and wetlands

• An urban standard stormwater drainage system
