Summary of Post-Construction Stormwater

Post-Construction Stormwater Programs in North Carolina

There are various post-construction programs throughout the state, some of which require a permit from local governments and others that are permitted by the NCDEQ. Not all areas of the state have post-construction stormwater programs. The best way to identify which program applies and the proper jurisdiction to contact is to search for the development site on the Interactive Stormwater Permitting Map. In general, the following post-construction programs are implemented by local governments:

• Water Supply Watersheds 

• Neuse, Tar-Pamlico, and Falls Lake
