In June 2016, Council formally endorsed the draft Overland Flow Flood Study for the Hurstville, Mortdale and Peakhurst Wards. The Overland Flow Flood Study forms part of an overall future Floodplain Risk Management Plan for the Georges River Council area.
The key objective of the Plan is to reduce the impact of flooding and flood liability on individual owners and occupiers of flood prone properties. The Plan also aims to reduce potential private and public losses resulting from floods, utilising ecologically positive flood mitigation measures. The Overland Flow Flood Study is the first step in developing the Floodplain Risk Management Plan and involves a comprehensive technical investigation of flood behaviour within the area.
The Flood Study provides detailed information on the nature of the flood risk including the distribution, extent, levels and velocity of floodwaters across the floodplain for various flood events including the 100 Year Flood and Probable Maximum Flood.
