Floodplain Risk Management Study and Plan

The Flat Rock Creek Floodplain Risk Management Study and Plan constitutes the second and third stages of the management process for the catchment. They have been developed for Willoughby City Council by WMA Water for the future management of flood liable lands in the Flat Rock Creek Catchment. The study firstly details the extent, risk and cost of flooding throughout the catchment. This information is then used to develop a plan to mitigate the risk of flooding throughout the catchment with recommended strategic and capital projects prioritised.
