3. Why is the CCMA erosion rate in most places, much higher than long term study areas, such as Pennington Point and East Beach, and Seaton Hole?
Fundamentally, the difference is due to a reasonable worst case scenario being modelled for the CCMA, and a most likely (actual) erosion rate being used for our studies. The CCMA rate also has additional 10m safety buffer, which is not included on our existing local studies.
