Erosion prone areas
The erosion prone area is the width of the coast that is considered to be vulnerable to coastal erosion and tidal inundation over a 50-year planning period. Where no regional coastal management plan has been prepared, an area within a designated Erosion Prone Area is taken to be a coastal management district under Section 168 of the Coastal Act. Calculation of the erosion prone area is based on:
- a short-term erosion component from extreme storm events;
- a long-term erosion component where gradual erosion is occurring;
- a shoreline recession component due to sea level rise associated with climate change; and
- a dune scarp component, where slumping of the scarp face occurs following erosion.
Additional information on coastal erosion and assessment of erosion prone area widths is available: Coastal erosion and assessment of erosion prone area widths.

Erosion prone areas occur in all local government areas and are described on the following plans:
