Natural hazards - coastal and flooding considerations
Many cities and towns in Australia are located on the coast, so it is important that Australian governments plan settlements that can respond to the constantly changing coastal environment.
As a local government, Eurobodalla Shire Council has a responsibility to our community to preserve the coast for its natural beauty, the major contribution it makes to our economy and lifestyle, and to make sure our settlements are resilient to the natural hazards associated with the coast.
With around 110km coastline and over 50 beaches under our care and control, Council has more coastal management responsibilities than most NSW local governments.
We must also consider the impacts of climate change. Our local towns are vulnerable to sea level rise, with many homes, businesses, public infrastructure and natural places potentially at risk.
Council has adopted a regional risk management based approach toward planning for sea level rise. This aims to allow the community to gain economic benefits from the coast without denying future generations the chance to enjoy the same lifestyle benefits we enjoy today. Our community helps to work toward these goals through our Coastal Management Advisory Committee.
Council adopted the Interim Coastal Hazards Adaptation Code (the Code) in February 2015 to guide the assessment of Development Applications in areas potentially at risk from coastal hazards. By having the Code in place, Council is meeting its legal requirements to consider coastal hazards when assessing Development Applications. The Code is triggered when a Development Application is lodged.
The Code applies as a temporary guideline until we have completed the process of developing a Coastal Management Program.
You can read the Code, together with the Moruya Floodplain Code, on our development control plans and codes web page.
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.
Coastal management projects and studies
Local councils are responsible for managing the risk to people, towns and infrastructure from coastal hazards. This involves reducing or avoiding damages caused by coastal storms such as erosion of beaches, inundation from storm surges and longer term processes such as sea level rise. Council is working on a Coastal Management Program which, when completed, will be the primary tool for managing these hazards.
Wharf Road Coastal Zone Management Plan
The plan contains a set of management aims, objectives and actions that protect and enhance.
Coastal Hazards Scoping Study
This study identified areas that are most at risk from coastal hazards and in need of a management response in the Coastal Management Program.
Eurobodalla Coastal Management Program (beaches and headlands)
Council is helping to make sure the Eurobodalla coast is managed and developed in a way that protects our natural features and supports ongoing growth.
