FCC has undertaken a number of recent mainstream flood studies, including:

• Cabramatta Creek Flood Study
• Prospect Creek Flood Study *? Georges River (FCC section) Flood Study
• Orphan School Creek, Green Valley Creek and Clear Paddock Creek Flood Study.

These studies provide accurate flood levels that are invaluable for planning development on, and close to, floodplains. However, there are many other areas in Fairfield that are potentially flood prone but have not been studied or mapped, including areas in the current study area. Those areas in the study area, which have been previously assessed, were considered between 10 and 20 years ago using different modelling techniques and to varying levels of detail. Hence, the present understanding of flooding conditions in the current study area is not one that is fully integrated.

This current study, therefore, aims to determine the mainstream flooding conditions, including flood levels, flow rates and flood risk, in the study area in an integrated manner, in line with the previous studies recently undertaken for Prospect Creek, Cabramatta Creek and the Georges River.

Further, this study also intends to account for any physical changes within the catchment that have occurred since the previous flood studies, which would contribute to changes in the design 100 year ARI flood levels. Subsequently, FCC intends to use the latest flood information from this study to update the Section 149 Certificates for the flood affected properties within the study area.

As per the floodplain management framework set out in the Floodplain Development Manual 2005, this Flood Study is part of a process that subsequently involves the undertaking of a Floodplain Risk Management Study and development of a Floodplain Risk Management Plan. The Flood Study will be used as the basis for developing a Floodplain Risk Management Study and Plan for the Flood prone land within the study area, in which the end result of the process will be the development of management measures so future flood risk can be managed, reduced or eliminated.
