Local councils are responsible for managing flood-prone land in NSW with support from the NSW Department of Planning, Industry and Environment (DPIE), which provides specialist technical knowledge.
Council is developing a range of floodplain risk management studies that will help us consider the consequences of living on flood-prone land. The plans aim to minimise the losses to our community from flooding.
A flood study is a technical project that identifies flood behaviour such as depth, velocity and extent across the floodplain. It includes using historical data from past flood events to calibrate a model that will estimate flood risk from a range of rainfall events.
Preparing a flood study is the first step in the floodplain risk management process outlined in the NSW Floodplain Development Manual.
A flood study does not propose any actions to manage flood behaviour - this occurs in the Flood Risk Management Study and Flood Risk Management Plan stages of the process.
Studies in progress
Batemans Bay Urban Creeks Flood Study
Some parts of the Eurobodalla Shire are more prone to flooding than others, and Council is committed to finding solutions to reduce the social and economic damages of flooding.
Narooma Coastal Inlets Floodplain Risk Management Study and Plan
This project supports Council's commitment to finding solutions to reduce the social and economic damages of flooding in areas previously identified as being flood-prone.
Adopted flood studies
Moruya Floodplain Management Plan
This plan aims to ensure that flood-liable land is planned and managed with regard to social, economic and ecological costs and benefits, as well as community safety, health and welfare requirements.
Tomakin, Mossy Point, and Mogo Flood Study
This study provides information on flood behaviour, including flood levels, potential hazards and projected impacts from climate change.
Wagonga Inlet, Kianga, and Dalmeny Flood Study
One of the primary objectives of this study is to provide a model that can establish the effects of flood behaviour of future development, and to assess the sensitivity of flood behaviour to potential climate change effects.
