FLOODPLAIN RISK MANAGEMENT STUDY

The specific aims of this study are to:

• review the results from the Flood Study,
• identify development and planning controls to regulate redevelopment in the flood affected properties and to ensure that future redevelopment does not significantly add to the overall potential damages,
• make recommendations to adopt Flood Planning Levels (FPL) appropriate for the catchment,
• investigate available floodplain risk management measures along with prioritisation, staging of works and preliminary costings.

The subsequent Floodplain Risk Management Plan will document the recommended strategies.

FLOODPLAIN RISK MANAGEMENT MEASURES

A list of all possible floodplain risk management measures which could be applied in the study area were initially developed for consideration. The assessment extended to examination of potential future development and its possible adverse impacts on flows and water quality. The Green Square – West Kensington Floodplain Risk Management Study measures were then assessed in terms of their suitability and effectiveness for reducing social, ecological, environmental, cultural and economic impacts. As part of this process a number of measures were identified as not being worthy of further consideration.

A summary of the various floodplain management measures considered during the course of the study is presented in Table (i) together with a brief assessment of their viability for implementation as part of the Floodplain Risk Management Plan for the Green Square – West Kensington catchment.

RANDWICK CITY COUNCIL FINALISATION - October 13, 2011

It is necessary to note that the City Of Sydney is currently investigating floodplain management measures for the Green Square Town Centre. This location is significantly downstream from the Randwick City Council local government area and any resulting amendments will not have any impacts on the Randwick City Council portion of the catchment.

As such, this study is now finalised as it relates to the Randwick City Council local government area. Details for the City of Sydney local government area are still in draft form and should not be relied upon until finalised.
