1. INTRODUCTION AND BACKGROUND

This Study has been prepared by WMAwater on behalf of the Shoalhaven City Council (Council). The Study is composed of three phases:

1. Revision of the 2006 Currambene Creek and Moona Moona Creek Flood Study (Reference 1);
2. Preparation of the Currambene and Moona Moona Creek Floodplain Risk Management Study; and
3. Preparation of the Currambene and Moona Moona Creek Floodplain Risk Management Plan.

This document details all three phases of work. The FRMS&P follows on from the Flood Study revision which defines the flood behaviour in Currambene and Moona Moona Creeks under existing conditions to determine the nature and extent of the flood problem.

1.1. Objectives This project involves preparing a Floodplain Risk Management Study and Floodplain Risk Management Plan (FRMS&P) for Currambene and Moona Moona Creeks. The main objective of this FRMS&P is to identify potential floodplain risk, test amelioration strategies for the management of risk and to put forward priorities and approximately costed recommendations in regards to flood risk mitigation in the Study Areas. The Currambene Creek Study Area is presented in Figure 1 and the Moona Moona Creek Study Area is presented in Figure 2. Council requires consideration of a range of management options to effectively manage existing, future and continuing flood risks in the region. The outcomes from the Flood Study revision, Floodplain Risk Management Study and Floodplain Risk Management Plan will also assist the SES in preparing a Local Flood Plan for the region. The information and results obtained from the Flood Study revision (see Section 3.3), define existing flood behaviour and provides a firm basis for the subsequent FRMS&P which constitutes Phases 3 & 4 of the overall work (see Sections 5 to 9).
