The Mullet Creek Floodplain Risk Management Plan (FRMP) has been prepared for Wollongong City Council (hereafter referred to as Council) in accordance with the New South Wales (NSW) Flood Prone Land Policy and the principles of the Floodplain Development Manual (NSW Government, 2005). The FRMS (Rhelm, 2022), examined options for managing flood risk in the suburbs of Dapto, Horsley, Wongawilli, Dombarton, Huntley, Cleveland, Kembla Grange, Avondale, Brownsville and Kanahooka. This FRMP outlines the floodplain management measures recommended as an outcome of the assessment undertaken in the FRMS along with the implementation strategy associated with those measures. The FRMP is to document and convey the decisions on the management of flood risk into the future. Drawing on the investigations undertaken as part of the FRMS, this plan outlines a range of measures to manage existing, future and residual risk effectively and efficiently. This document also presents a prioritised implementation strategy, to guide the implementation of the proposed measures.
