Bass Coast,

Land Subject To Inundation Overlay

Bass Coast Shire Council has prepared Amendment C82 to the Bass Coast Planning Scheme.

This amendment proposes to apply the Land Subject to Inundation Overlay (LSIO) across areas in the municipality that have been identified as being at risk of inundation from recent flooding research.

Areas identified include land affected by catchment flooding, tidal inundation and from coastal inundation resulting from predicted future sea level rise.

Mayor, Cr Neil Rankine, said the community would benefit in having access to the current inundation information.

“Council wants to ensure land owners are informed with up-to-date information regarding flooding to assist in making the right decisions regarding new development,” Cr Rankine said.

“Providing this information in the Bass Coast Planning Scheme allows landowners and developers immediate access to the necessary information about flooding so that any affected areas can be identified and considered in the early stages of the development process.

“This will help to ensure that new development is designed with inundation risk in mind.”

 “It is important to emphasise that this amendment does not seek to prohibit development – its purpose is to ensure new developments in affected areas are responsive to the risk of flooding and inundation,” Cr Rankine said.

Cr Rankine said the amendment had been prepared in partnership with Melbourne Water and West Gippsland Catchment Management Authority.

“Melbourne Water and the West Gippsland Catchment Management Authority are the Floodplain Management Authorities for the Bass Coast Shire Council area.

“The mapping is a combination of their data and the State Government’s Future Coasts Inundation Dataset, provided to Council by the (now) Department of Primary Industries and Environment,”Cr Rankine said.

“The mapping is based on the best available information to date and Council welcomes further discussion of the inundation extents.

All documents and maps related to Amendment C82 are available for public inspection at Council offices in Wonthaggi, Inverloch, Cowes and Grantville, as well as on Council’s website ( and at the Department of Transport, Planning and Community Development website (

In addition, Council will be holding a number of drop-in sessions planned for residents affected by Amendment C82, running from 23 March until 23 April. Details about these are available at

“I encourage you to get involved, and if you cannot make it to any of these, please contact our Strategic Planning Department on 1300BCOAST(226 278) to discuss your issues or concerns, and seek clarification,” Cr Rankine said.
