Long-Term Average Annual Erosion Study

These maps are for general information only. They illustrate average rates of shoreline change over approximately 50 years. The information presented here is not predictive, nor does it reflect the short-term erosion that occurs during storms.

The erosion rates depicted in these maps have been adopted  by the Coastal Resources Commission for incorporation into oceanfront setback rules (January-2004). These data are used as factors in determining setback distances for oceanfront construction. These maps may not be suitable for property-specific determinations of setback distance because of their scale. For a site-specific determination, contact your CAMA Local Permit Officer or the nearest regional field office of the N.C. Division of Coastal Management.

The 1998 long-term average annual shoreline change rate was developed by N.C. State University’s Kenan Natural Hazards Mapping Program and N.C. Division of Coastal Management
