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. At this stage, five 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 and the Birds Gully and Bunnerong Road Catchment.

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

Randwick City Council commenced a Floodplain Risk Management Study and Plan for this catchment in May 2021. 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 August 2022. Community consultation is expected to occur in two phases, in February 2022 for input to the study, and September 2022 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.
