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.

Map Tutorial on how to use this map

Tips for finding your location:

  • Latitude and longitude are in decimal degrees (rather than degrees, minutes, seconds).  Be sure the longitude is a negative number.
  • Some addresses will not be found.  Please zoom into your area, click the “locate” (mailbox) icon, and click as close to the point of interest as possible.
  • Alternatively, move the mouse over a location and jot down the X and Y coordinates.  Type these into the latitude (Y) and longitude (X) fields.

Interactive Map for Stormwater Permitting Areas

Map last updated July 16, 2008

Important Information about map results:

  • Please pay attention to the “Note” section returned about your location. In some cases, overlapping stormwater programs mean more than one permit could be required. Usually this is where “Permitting” says “Multiple” (but sometimes both programs will be "Local"). The interactive map can’t return more than one permitting contact, so please consult this guidance for when multiple permits are needed. (Note - Revisions reflecting new Coastal Stormwater Rules are pending)
  • Post-construction stormwater permitting requirements STILL APPLY in "Exempt" Phase II cities and ETJs. This only means the town or city was "exempted" from a permit to implement a Phase II stormwater program at the local level. Development projects in those jurisditions must comply with state post-construction requirements. The map no longer returns the term "Exempt" to avoid confustion.
  • Where the Permitting Authority is the “State,” the contact may be the Regional Office (RO) or the Central Office (CO).  The appropriate office is identified, and the regional office is noted for all locations. 

    • Effective July 1, 2007, the Central Office handles most Phase II Post-Construction permits in the unincorporated areas and in "tipped counties," except in coastal counties.
    • The Regional Offices handle all Post-Construction permits in HWQ/ORW areas throughout the State and in coastal counties. Note: New, more stringent Coastal Stormwater Rules became effective October 1, 2008.

  • In Phase II Coastal (CAMA) Counties outside incorporated town limits, you need to apply to the DWQ Regional Office for a State Stormwater (SSW) Post-Construction permit. New, more stringent Coastal Stormwater Rules became effective October 1, 2008.

  • In Phase II Coastal (CAMA) Counties inside incorporated Phase II town limits, you need to apply to the DWQ Regional Office for a Post-Construction permit (EVEN THOUGH THE MAP INDICATES ‘LOCAL’ CONTACT).  Eventually—when that jurisdiction begins its Post-Construction program—you should only need a Post-Construction permit from that local government. 
  • Contact the local jurisdiction to verify that your project is outside incorporated city boundaries.  These boundaries change more frequently than we can update the map, and the map is missing ETJ boundaries in some areas.  In any Phase II city or town, you will need to verify whether the project is located (1) inside city limits, (2) inside the ETJ, or (3) outside both.  If the answer is outside both, apply to the DWQ Central Office (or Regional Office in CAMA counties) for a Post-Construction Permit.  For coastal counties only: If the project is inside city limits or the ETJ, but the town is not yet implementing Post-Construction, apply to the appropriate DWQ Regional Office.
