This community consultation has now closed and information on this page may no longer be current.

There has been a number of floods in the Maroubra Bay catchment in the past and the two most memorable floods were in 1959 and 1999.  There have also been a number of smaller floods over the years.

Randwick Council has prepared a Draft Maroubra Bay Flood Study for the catchment that drains towards Maroubra Bay, between Anzac Parade and the Pacific Ocean - an area of approximately two and a half square kilometres.

This Draft Flood Study sets out the frequency and severity of flooding in the study area, using historical and technical information.

The Study gives residents the information they need to prepare for floods and gives Council the information it needs for future planning.

You can contact Council's Drainage Engineer Mr Terry Kefalianos on 9399 0525 for more information on the flood study and the community information session.

The next steps

At the end of the public exhibition period, all comments and submissions will be carefully considered and the draft Maroubra Bay Flood Study report will be changed where necessary and reported to a Council meeting.

Council will then look at the options to manage flooding and will start work on a Floodplain Management Plan. Council will consult the community as part of developing the Management Plan.


In NSW, local councils are responsible for managing local area flooding and Randwick City Council is undertaking flood studies for each of the major catchments in the City.

The NSW Government's Floodplain Development Manual sets out the process for assessing and managing flooding issues in NSW. 

In 2007 the Council sent letters to all property owners all residents in the Maroubra Bay catchment and held a community kiosk at Maroubra Beach asking residents for their experiences of local floods.

This information from residents, together with the rainfall records and the locations and depths of past flooding, helped Council develop a comprehensive set of historical data for use as part of the study.

Detailed research was also undertaken to locate and measure the underground drainage network and a detailed survey was undertaken of ground levels.  This research was used to establish a computer model of flooding in the study area.

This computer model was tested against historical experience to confirm its accuracy and then used to determine the frequency and severity of flooding for properties in the study area.
