National Coastal Erosion Risk Mapping

The National Coastal Erosion Risk Mapping shows the coastal baseline which is split into ‘frontages’. These are lengths of coast with consistent features based on the cliff behaviour characteristics and the defence characteristics. It is intended as an up-to-date and reliable benchmark dataset showing the erosional extents and rates for three periods: short term (0-20 yr), medium term (20-50 yr) and long term (50-100 yr).

The 5th, 50th and 95th percentile confidence levels are presented as distance (in metres) of erosion/accretion cumulative over time using both the No Active Intervention policy scenario and with the implementation of Shoreline Management Plan 2 policies.

Please note: The data and associated information is intended for guidance - it cannot provide details for individual properties. The data does not estimate the absolute location of the future coastline.
