Summary of Post-Construction Programs

In North Carolina, there are a variety of post-construction programs. The Post-Construction Stormwater Map indicates which program applies and the applicable jurisdiction to contact.

We do our best to make the map as accurate as possible, it is advisable to check with the local government if the map shows that your project is not subject to a stormwater program.
