Lower Macleay Flood Study

Community Life - 27 March 2018

A comprehensive flood study of the Lower Macleay Floodplain is currently being undertaken to identify and assess a range of flood risk management measures aimed at reducing the impacts of future flooding on the community.

Council, with financial and technical support from the NSW Office of Environment and Heritage, has engaged engineering consultants Jacobs Group (Australia) Pty Ltd to undertake the Lower Macleay Flood Study. 

Using current flood modelling techniques and aerial laser ground elevation survey information, the study will be a comprehensive flood modelling investigation to define flood behaviour.

In line with the NSW Government’s Flood Policy and Flood Development Manual, the study is the first stage in developing a revised Lower Macleay Flood Risk Management Plan.

Council’s Senior Natural Resources Officer, Ron Kemsley, said the study will focus on flood behaviour and dynamics for the entire Lower Macleay floodplain.

“There will be a particular emphasis on floodplain villages, flood mitigation infrastructure and flood flow ocean outlets,” Mr Kemsley said.

“Information from the study will assist council in identifying, understanding and preparing for flood management for the Lower Macleay as well as assisting council with future planning and development responsibilities.”

The draft flood study is expected to be completed towards the end of 2018. Residents will be able to view and comment on the draft when it is placed on public exhibition.

Coastal Management Scoping Studies

Studies are also currently being undertaken for the Macleay River, Killick Creek and Korogoro Creek estuaries.

As part of NSW Government Coastal Management Reforms, Council is required to upgrade the existing management plans for these estuaries

Council has engaged Coastal Management Consultants BMT to undertake scoping studies which involves looking at current management measures and considering either new or alternate measures or opportunities for improvement.

The studies, which should be completed by late 2018, will help determine what processes are required to prepare the plans.
