The Duck Creek Flood Study has been prepared for Wollongong City Council (Council) to define the existing flood behaviour in the Duck Creek catchment and establish the basis for subsequent floodplain management activities. The Duck Creek catchment encompasses an area of approximately 19 square kilometres located in the Yallah region on the New South Wales South Coast. Duck Creek flows in a general east direction from its headwaters below the Illawarra Escarpment to its confluence with Lake Illawarra at Yallah.
The overall objective of this study is to improve understanding of flood behaviour and impacts, and better inform management of flood risk in the study area through consideration of the available information, and relevant standards and guidelines. The study will also provide a sound technical basis for any further flood risk management investigations in the area. The project provides an understanding of, and information on, flood behaviour and associated risk to inform:
- relevant government information systems;
- government and strategic decision makers on flood risk;
- the community and key stakeholders on flood risk;
- flood risk management planning for existing and future development;
- emergency management planning for existing and future development, and strategic and development scale land‐use planning to manage growth in flood risk; and
- decisions on insurance pricing (where the information is utilised by insurance companies).
The study outputs will also inform decision making for investing in the floodplain; managing flood risk through prevention, preparedness, response and recovery activities; pricing insurance, and informing and educating the community on flood risk and response to floods.
