Stormwater Unit :: Stormwater Program Map Resources

The Department, Division and NC Center For Geographic Information and Analysis have worked to establish an interactive web-based mapping system to help development activities determine whether they are covered by the post-construction permitting program or other Stormwater permitting requirements.  Please read the notes below associated with the use of information from this mapping system.  As with any system of this type, it should be viewed as simply a tool to help you in making your final determination about your responsibilities for permit coverage.

Please verify that the local government in your location does not require more stringent stormwater controls than the information provided by this map.  For example, some counties will opt to implement Post-Construction countywide. Also, some counties have new areas subject to Water Supply or State Stormwater programs. Corrections are also noted.
