Coastal Stormwater Rules

The first State Stormwater Management Program began in the late 1980s under the authority of the N.C. Environmental Management Commission and N.C. General Statute 143-214.7.  This program, currently codified in 15A NCAC 2H .1019, is applicable to:
  • Non-residential projects adding more than 10,000 square feet of built upon area (20 coastal counties only)
  • Development activities that require either an erosion and sediment control plan (for disturbances of one or more acres) or a CAMA major permit within one of the following areas:
    • The 20 coastal counties, and/or
    • Draining to Outstanding Resource Waters (ORW) or High Quality Waters (HQW)

In addition, residential development activities that will add more than 10,000 square feet of built upon area resulting in a total built upon area greater than 12% of the site, must apply for the general stormwater permit SWG050000 if the activity disturbs less than one acre, is located within the 20 coastal counties within 1/2 mile and draining to class A shellfishing waters.
