Floodplain Risk Management Study and Plan

Towradgi Creek Flood Study, Floodplain Risk Management Study & Plan 2023

Towradgi Creek is located within the Wollongong City Council Local Government Area (LGA). The 7.5km2 catchment incorporates the northern Wollongong suburbs of Tarrawanna, Corrimal, East Corrimal and Towradgi, and extends from the Illawarra Escarpment in the west, discharging at Corrimal Beach in the east.

In this study, a full assessment of the existing flood risk in the catchment has been carried out, including hydraulic hazard across the study area, over floor flooding of residential, commercial, and industrial properties, identification of known flooding issues and hotspots, and emergency response during a flood event. Various measures aimed at managing this flood risk were assessed for their efficacy across a range of criteria. The options were rated according to a detailed matrix of possible impacts. Those rated highest have been recommended in the Floodplain Risk Management Plan, and prioritised based upon how readily the management measures can be implemented, their capital cost, what constraints exist and how effective the measures are. Measures with little cost that can readily be implemented, and which are effective in reducing damage or personal danger would have high priority.
