Stream & Wetland Mitigation Program
If a proposed development project has explored all practical alternatives for avoiding and minimizing impacts, and project impacts exceed applicable permit thresholds, then mitigation will be required. The mitigation plan must be implemented and/or constructed before any permanent building or structure on site is occupied. In the case of a public road project, the mitigation plan must be implemented before the road is opened to the public. Proof of payment into a mitigation bank or in-lieu fee program or completion of an approved permit-specific mitigation project must be provided to DWR to satisfy this requirement. Options for compensatory mitigation include:
-
Mitigation banks: Applicant satisfies the mitigation requirement by purchasing mitigation credits from an approved mitigation bank.
- In-lieu fee mitigation: Applicant satisfies the mitigation requirement by purchasing mitigation credits through the N.C. Division of Mitigation Services.
- List of active DMS projects with DWR project numbers (for Mitigation Project Information Upload Form)
- Permittee Responsible mitigation: Applicant satisfies the mitigation requirement themselves, either at the project site or at an off-site location.
In accordance with 15A NCAC 02H .0506(c) and 15A NCAC 02H .1305(c), the DWR requires compensatory mitigation for losses of streams and wetlands (404 jurisdictional wetlands as well as isolated and other non-404 jurisdictional wetlands) as follows:
- For linear public transportation projects, mitigation shall be required for impacts equal to or exceeding 300 linear feet per perennial stream or 0.10 acre of wetlands per impact location.
- For all other projects, mitigation shall be required for impacts equal to or exceeding 300 linear feet of perennial streams or impacts equal to or exceeding 0.10 acre of wetlands for the entire project.
For impacts to federally jurisdictional waters requiring compensatory mitigation, information on mitigation options can be viewed at the U.S. Army Corps of Engineers Mitigation Web Site.
