Stream & Wetland Mitigation Bank

​The City of Charlotte's Stream and Wetland Mitigation Bank provides Charlotte with a source of funding for improving streams and wetlands, and ensures that some federally required mitigation projects are constructed within Mecklenburg County instead of hundreds of miles away.

Between 2001 and 2020, approximately 24 miles of streams were improved and 
34 acres of wetlands were either improved or preserved through the Mitigation Bank.

Municipal projects, such as new roads, schools and water lines, are necessary for a growing community. Occasionally, these projects must impact streams and wetlands. Section 404 of the Clean Water Act requires streams and wetlands impacted by construction to be compensated with the restoration, enhancement, and/or preservation of streams and wetlands in a different location; often at a higher ratio. This is called stream and wetland "mitigation" and must be implemented within the same regulatory watershed where impacts occurred. Unfortunately, regulatory watersheds are very large so mitigation can occur hundreds of miles away from its impact.

In 2004, the City of Charlotte established North Carolina's first municipally-owned Stream and Wetland Mitigation Bank where "mitigation credits" are generated when Charlotte-Mecklenburg Storm Water Services restores, enhances or preserves streams or wetlands in Mecklenburg County. These credits can be bought by City or County agencies to offset impacts caused by their construction projects. Once credits are bought, the Mitigation Bank can then fund more local stream and wetland projects.

The Bank benefits local watersheds by ensuring that stream and wetland impacts from City and County infrastructure projects are mitigated within Mecklenburg County, not hundreds of miles away.
