Managing flooding

Randwick's flood management programs

Flood Management Process

Randwick City Council is progressively studying all catchments within its local government area in accordance with the NSW Government's Floodplain Development Manual.  The Floodplain Management Process is outlined below.

Floodplain Management Process

The objective of a Flood Study is to identify the nature and extent of flooding within a catchment.

The next step is to undertake a Floodplain Risk Management Study and Plan. The outcome of the study and plan is the development of strategies to reduce the risk of flooding to people and properties within the catchment. It considers various options to manage flooding including works to reduce flood levels, development controls, education and emergency management.

Flooding information is made available to the public when flood models are considered reliable.

Information available

The status of each study is described on the following map PDF, 735.95 KB. At this stage, six catchments have been studied and one is underway.

Property specific information is available for properties within the Green Square West Kensington catchment, the Maroubra Bay catchment, the Coogee Bay catchment, the Kensington - Centennial Park catchment, the Birds Gully and Bunnerong Road catchment and the Lurline Bay, Matraville, Malabar and Yarra Bay catchment.

This information can be requested via the Flood Report Application Form.

The study is currently in its inception stage where the consultants are collecting and collating data on flooding and the catchment and, reviewing and updating the available flood models. These computer models will provide the technical information for assessment of the effectiveness and feasibility of various flood mitigation measures. A draft report for the Floodplain Risk Management Study is due for completion in October 2023. Community consultation is expected to occur in December 2023 for public exhibition of the report.

Flooding Advice and Flood Related Development Controls Policy

A significant period of time can elapse from the point where Council becomes aware of the risk of flooding, to the point were Council adopts a Floodplain Risk Management Plan outlining how the flooding will be managed.

The Flooding Advice and Flood Related Development Controls policy provides guidance on how flooding related matters will be considered during this period.  The policy was adopted by Council on 28 February 2012.
