New Hanover County enacted a Stormwater Ordinance on September 5, 2000. The ordinance covers stormwater management as well as drainage concerns within the unincorporated areas of New Hanover County. All development requiring stormwater management controls must have plans and specifications submitted for review and approval. Please contact the Engineering Department for assistance with stormwater or drainage questions. Additional information can be found below:

Development in New Hanover County is also subject to the North Carolina Coastal Stormwater Regulations, enforced by the NC Department of Environmental Quality (NCDEQ). Additional agency approvals may be required. Check the NCDEQ website to determine applicable regulations.

Note: New Hanover County does not control or regulate stormwater within the City of Wilmington, the Town of Carolina Beach, Kure Beach, or Wrightsville Beach, or stormwater conveyances along North Carolina Department of Transportation (NCDOT) roadways.

For any stormwater questions or concerns, please contact Phil Bevilacqua, PE, by email at, or by phone at 910-798-7072.
