The purpose of this Flood Study is to identify local overland flow as well as mainstream flow and define existing flood liability. This objective is achieved through the development of a suitable model that can also be used as the basis for a future Floodplain Risk Management Study and Plan for the study area, and to assist the Inner West Council (IWC) when undertaking flood-related planning decisions for existing and future developments. The primary objectives of this study are to:

• prepare suitable models of the catchment and floodplain for use in a subsequent Floodplain Risk Management Study;
• provide results for flood behaviour in terms of design flood levels, depths, velocities, flows and flood extents within the study area;
• prepare maps of provisional hydraulic categories and provisional hazard categories;
• determine provisional residential flood planning levels and flood planning area;
• prepare preliminary emergency response classifications for communities; and
• assess the sensitivity of flood behaviour to potential climate change effects such as increases in rainfall intensities and sea level rise.
