Floodplain Management

Flooding in Wollongong

Flooding is when the water level in a creek, river, lake or the sea rises and covers land. Whilst some floods occur without problem, others are devastating, causing large-scale destruction and significant loss of life. The rise in water level can be due to numerous causes, although the most common in Australia is heavy rainfall.
Flooding that is sudden and unexpected is referred to as flash flooding. It is usually caused by slow-moving thunderstorms that deposit an extraordinary amount of water in a relatively short period of time.

Due to our location at the foot of the Illawarra Escarpment, Wollongong is particularly prone to flash flooding. As heavy rainfall occurs along the escarpment, runoff reaches the creeks very quickly, giving local residents little time to prepare.

Floodplain Risk Management Committees operate in accordance with the adopted Floodplain Risk Management Committee Charter [182 KB]. The Committees include community members, Councillors, Council staff and officers from State Government agencies. A ‘technical sub-committee’ is available to support each committee by providing expert advice on technical matters.

What’s involved?

embers will be expected to attend meetings aembers will be expected to attend meetings at key milestones of the projects. Given the large number of flood studies that will be reviewed, it is likely that combined committee meetings will be held for neighbouring catchments, as the review progress may be at different stages and some committees may only be formed and start to operate later in the year.

We invite you to express your interest in being considered as a local community representative in one or more of our Floodplain Management Areas. The appointment of community members will be in accordance with Council’s Recruitment of External Members to Committees Policy.

The following selection criteria will be used to assess applications, with suitable candidates invited to attend an interview with the selection panel:
