Council will conduct investigations to gain a deeper understanding of flood events on Raymond Island, with the goal of proposing solutions to mitigate ongoing flooding issues.

Raymond Island has historically experienced flooding when the water levels of the Gippsland Lakes increase following the flooding of the rivers that flow into them - the Latrobe, Thomson, Macalister, Avon, Mitchell, Nicholson, and Tambo Rivers. This has been prevalent throughout 2021 and 2022 with large volumes of recorded rainfall during the La Niña climate pattern.

Existing flooding cannot be addressed properly through means of regular maintenance, given the low land levels on the island; it is well acknowledged that land levels on Raymond Island are too low for a drainage system to rely only on underground drainage. The existing drainage assets have very limited fall and are impacted by tidal water preventing the system from running effectively.

All options will be investigated to alleviate the continuous flooding, including measures to retard the flow entering the existing stormwater network.

Objective and scope

Through this project we aim to create a comprehensive stormwater drainage plan for Raymond Island, which involves conducting site investigations, hydrological and hydraulic modeling, and formulating a stormwater strategy alongside conceptual designs for key drainage components.

Consultation and community engagement

We welcome your feedback and invite you to tell us of your experiences of flood-prone locations across Raymond Island to inform the development of this project; feedback is vital to ensure we create a comprehensive stormwater drainage plan for Raymond Island.

to complete the survey


Feedback from the preliminary investigation and flood modelling will be shared with residents via the YourSay page.

Schedule

This project has not yet been programmed for detailed design or construction. The development of the comprehensive stormwater drainage strategy will inform the next steps.

Funding

This project is funded by East Gippsland Shire Council.
