Various floodplain management measures have previously been investigated for specific problem areas along the Georges River. In many instances, the recommended measures have been adopted and implemented by the relevant Council. The floodplain risk management study will review the effectiveness of those measures as well as examining other potential measures to reduce the risk of flooding.

Measures that will be considered as part of the current study include:

Review of existing flood mitigation works

• Carinya Road deflector levee and finger levees

• East Hills finger levees

• Kelso Creek levee

• Moorebank Voluntary Purchase Scheme (Liverpool Council)

• Milperra Voluntary Purchase Scheme (Bankstown Council)

• Milperra Drain Channel Improvement Works

• Rabaul Road Development Controls

Other potential flood mitigation works

• Dredging the river to increase its capacity

• Construction of upstream dams or detention basins to temporarily store floodwater during floods

• Construction of levees in other places to protect property

• Channel and culvert improvement works in tributary creeks (eg on Little Salt Pan Creek or Salt Pan Creek)

Measures that modify property

• Raising of houses above the 100 year flood level;

• Flood-proofing of individual properties by waterproofing walls and/or deflector banks;

• Controls on future development in flood liable areas (eg. Minimum floor levels, controls on the extent of filling allowed on properties, etc.);

Measures that modify people’s response to flooding

• Improvements to flood warning both before and during floods;

• Improving evacuation procedures and emergency management plans;

• Promoting public education, community participation and flood awareness programs;

• Making sure all information about the potential risks of flooding is available to all residents and business owners;

• Providing information to residents or property owners stating whether their property is subject to flooding;

• Making sure residents and business owners have Flood Action Plans – these outline what to do, where to go and who to contact in a flood;

• Installing some flood markers (for example on telegraph poles) to act as constant reminders of the heights of previous floods.

If you would like to suggest any other measures that you think the study should also assess, or if you would like to offer your opinion on any of the measures listed above, please provide your feedback below.
