Floodplain Risk Management Study

Cabbage Tree Creek Floodplain Management Study

The objectives of the Cabbage Tree Creek Floodplain Management Study are to investigate the feasibility of a range of floodplain management strategies to alleviate existing flooding problems, and to propose a program of works and non-structural measures to form part of a Floodplain Management Plan for the area.

Cabbage Tree Creek is located immediately to the north of the Wollongong CBD. The 10.3 square kilometre catchment area is bounded by the IlIawarra Escarpment in the west, a low watershed near Mt Ousley Road in the south and a low watershed near Balgownie Road in the north. The catchment of Cabbage Tree Creek is extremely steep in the upper parts. From the crest of the IlIawarra Escarpment to the upper limits of residential development some 3 km downstream, the average creek slope is 10% with slopes up to 30% in places. Upstream of Brokers Road the catchment is principally covered by forest and remains in a virtually natural condition. Slopes gradually flatten in the remaining 4 km to the confluence with Fairy Creek with the landforms changing to gently undulating and the average slope of the main stream reducing to 0.5%. Most of this lower catchment is highly urbanised with industrial and residential areas.
