Consultation has concluded

We’ve completed several studies to assess the flood risk within the Allans Creek Catchment. The risks are to people, property, infrastructure (e.g. roads and stormwater pipes) and assets (e.g. public parks and recreation areas). We’re now working on a Floodplain Risk Management Plan to look at ways to manage flood risk.

Measures used for managing flood risk
These measures might include groundworks in the catchment (e.g. drainage improvements and levees) to protect existing development and assets. We also consider using development controls and planning measures to reduce the risk of flooding to future development in the catchment. In addition, evacuation and emergency response planning will also be part of our approach to managing flood risk.

We’re asking the community to be involved in this flood risk management planning. We’d like to know where you think we should be focusing our efforts to protect existing homes, businesses, roads and other assets from flooding. We’d like you to be part of planning for flood-safe development into the future. We’ll work alongside the community and the State Emergency Service (NSW SES) so we can all respond to flooding in a coordinated, efficient and practical way.

Previous Community Input

The community has provided valuable input to previous flood investigations within the Allans Creek catchment. In 2006, they shared feedback with us as part of the previous Allans Creek Floodplain Risk Management Study. They provided accounts of their observations of previous flooding and shared feedback on the flood mapping through an online survey and community drop-in session. This input helped us to assess the suitability of a range of flood management measures for the catchment.

Flood risk management measures for the Allans Creek catchment
Using the previous flood investigations and input from the community, we’ve assessed a range of flood management measures for their suitability in reducing flood risk in the Allans Creek catchment. These include engineering works, vegetation management, development controls, planning measures and emergency response arrangements. These are some examples of each of these measures:

Engineering structures

Debris control structuresImproving drainage

Property modifications (existing development)

Voluntary house purchase

House raising

Development controls (future development)

Minimum floor levels


Emergency response and community awareness

Flood warning signsFlood plan

To find out more about the process for managing flood risk and how you can be involved in our planning:

Drop-in information session
At this session, we’ll have maps showing the location of the recommended measures for managing flood risk. The flood engineers who are working on the Floodplain Risk Management Study and Plan for this catchment will be there to answer your questions, explain what is being planned and how the proposed measures will help manage flood risks.

Date: Wednesday13 September 2023
Time: Anytime between 3:30-6:30pm - there's no presentation at this session, so you can drop in throughout the timeslot.
Where: Figtree Community Hall (West), 11 Princes Highway, Figtree

Accessibility, mobility or language assistance
