2019 NC Oceanfront Long-Term Average Annual Erosion Rates
The purpose of this study is to update ocean hazard construction Setback Factors and the Ocean Erodible Area of Environmental Concern which are based on the long-term average annual oceanfront shoreline change rates, commonly referred to as “erosion rates.” Initially established by the Coastal Resource Commission (CRC) under the Coastal Area Management Act (CAMA) in 1979, the long-term average annual shoreline change rates have been updated periodically since 1980, with the last update study completed in 2011, and effective on January 31, 2013. Oceanfront construction Setback Factors are used to site oceanfront development and determine the landward extent of the Ocean Erodible Area (OEA) within the Ocean Hazard Area of Environmental Concern (AEC), or the area where there is a substantial possibility of excessive shoreline erosion.
