Coastal Processes and Hazards Definition Study


The Coffs Harbour Coastal Processes and Hazards Definition Study is the first step in developing a Coastal Zone Management Plan to help tackle such risks in the Coffs Harbour local government area (LGA). The Study contains a thorough technical assessment of the possible threats posed by climate change, extreme weather and sea level rise.  

The Coffs Coastal Processes and Hazards Definition Study was developed by BMT WBM Pty Ltd consultants. Using the NSW Government's scientific guidelines and forecast sea level rise, it investigates the coastal processes occurring along the Coffs Harbour LGA coastline and the extent of the coastal hazards arising from these processes.

The Study looks at the likelihood of either coastal erosion or coastal inundation during extreme weather at three different timescales. These are 'Immediate', in the year '2050' and in the year '2100'. At each of these timescales, maps and hazard lines have been developed for the LGA that show erosion or inundation on the basis of 'almost certain', 'unlikely' and 'rare'.  

Please note that the purpose of the Study is simply to identify those potential coastal hazards. The Coastal Zone Management Plan will put in place the strategies needed to lessen the impacts of the identified potential hazards. It should also be noted that the coastal inundation zones shown in the maps are not permanent water levels, but illustrate forecast inundation during a storm event with or without sea level rise. 

See the Frequently Asked Questions (FAQs) for more information.

Study background:   

The Coffs Harbour City Council coastline extends for 79 kilometres from Bundagen Head in the south to Station Beach adjacent to Red Rock headland in the north. The Study area covers the immediate coastal environments such as beaches, dunes, headlands, bluffs, coastal entrances and waters and looks at the extent to which their management is affected by coastal processes and hazards and human activities.
