Lower Macleay Floodplain Risk Management Plan

Stage 1 Flood Study

In line with the NSW Government’s Flood Policy and compliant with the NSW Government’s Flood Development Manual, Kempsey Shire Council (KSC) is reviewing the existing Lower Macleay Floodplain Management Plan (1999) and undertaking additional flood investigations to prepare a revised Lower Macleay Floodplain Risk Management Plan. The Plan will present detailed evaluations of all factors that affect and are affected by the use of flood prone land and provide input into the strategic and statutory planning roles of council.

KSC with financial and technical support from the NSW Government Office Environment & Heritage (OEH) Flood Management Program have engaged engineering consultants Jacobs Group (Australia) Pty Ltd to prepare Stage 1 of the flood risk management process, the ‘Lower Macleay Flood Study’. The Flood Study constitutes the first stage of the flood risk management process.

Using current best practice flood modelling techniques and aerial laser ground elevation survey information the study will be a comprehensive flood modelling investigation to define flood behaviour and provide the technical foundation to develop a robust Flood Risk Management Plan.

When completed, the draft Flood Study will be placed on public exhibition for community and stakeholder comments and inputs.
