Long-Term Average Annual Oceanfront Erosion Rate Update
Updated long-term average annual erosion rates for North Carolina’s oceanfront have been approved by the Coastal Resources Commission and became effective Feb. 1, 2013.
A long-term average annual erosion rate is the average amount of erosion that occurs each year over a period of about 50 years. By measuring movement of the ocean shoreline over a long period of time, the Division of Coastal Management is able to get a more accurate representation of the net shoreline change, taking into account normal shoreline movement, beach nourishment and storms.
The newly adopted erosion rates are not substantially different from the rates adopted in 2003, as most of the oceanfront shoreline demonstrated very little change when compared to results from the previous study. From a regulatory standpoint, the new erosion rates, or setback factors, did not change for 64 percent of the shoreline.
