South Warrnambool Flood Investigation - the next stage

Consultation Closed: Friday, October 27, 2023 - 5:00 pm
What happened next

The next stage includes a community meeting on November 8 at the Merrivale Football Netball Club rooms from 5pm to 7pm.

What we consulted you about

The next stage in the South Warrnambool Flood Investigation involves seeking suggestions from residents and a community meeting.

The community is invited to provide written suggestions for flood mitigation solutions for South Warrnambool. 

Flood mitigation options will then be discussed at a meeting to be held at the Merrivale Football Club on Wednesday, November 8, from 5pm.

To ensure the suggestions are considered at the November 8 meeting, we require submissions to be received by 5pm, October 27.

The meeting will focus on selecting two flood mitigation options for high-level, pre-feasibility cost-benefit assessment, including modelling of the likely on-ground outcomes of the selected options.   

What are “mitigation options”?

•    Mitigation options are on-ground works to protect an area of land from inundation up to a certain level.  Mitigation works can never be expected to completely remove the risk of floodplain land from ever flooding again.  Constraints imposed by financial cost of implementation and potentially negative social and environmental costs, always limit to some degree, the amount of protection that can be realistically achieved from mitigation works.

•    In many instances, the mitigation analysis process completed by a flood investigation shows that there are no feasible mitigation options.

All suggestions received will be presented at the November meeting. Similar suggestions will be grouped together where appropriate.  Attendees at the meeting will then be asked to identify their top two preferred options.

A pre-feasibility cost-benefit analysis will be carried out on the two options identified at the meeting as the most preferred.

You can submit your mitigation suggestions by writing to contact@warrnambool.vic.gov.au or by dropping your written suggestion in to the Strategic Planning team at the Council offices at 25 Liebig Street, Warrnambool.

The investigation of riverine and storm tide (oceanic) flooding for South Warrnambool is a joint project between Council and the Glenelg Hopkins Catchment Management Authority with consultants Venant Solutions engaged to provide specialist expertise and advice.
