Predicted coastal erosion and flooding on the Coffs Harbour coastline has been outlined in a new study. The Coffs Harbour Coastal Processes and Hazard Definition Study looks at the possible effects of extreme weather events and sea level rise. It maps potential
risk areas and shows the extent of hazards during storm events.
The local council’s Ben Lawson says it is the first step in developing a strategy to protect risk areas. “The study does approach the problem from a worst case scenario,” he said.
“This stage of the process is to take the technical definitions that have been captured in the study out to the community, to discuss what these potential impacts are and then to formulate a management plan that will address these impacts.”
Mr Lawson says in the next stage a Coastal Zone Management Plan will be developed. “The modelling that we’ve carried out projects the sea level rise at 1.4 metres, to put that into perspective the State government has adopted a 0.9 sea level rise,” he said.
“The standards that we have adopted in a worst case scenario are giving us a snapshot of what is the worst thing we have to plan for.”
