WCA requires the replacement of the lost public value caused by unavoidable wetland impacts that comply with the special considerations of Minnesota Rule 8420.0515 and the sequencing requirements of Minnesota Rule 8420.0520.

Project-specific Wetland Replacement consists of implementing an LGU approved wetland replacement action that is eligible for credit under Minnesota Rule 5420.0526.

  • Project-specific wetland replacement must be sited, designed, and constructed the detailed standards of WCA, which include requirements such as ecological suitability and sustainability. Project-specific wetland replacement includes wetland monitoring and annual monitoring reports that typically continue for five growing seasons. LGUs may require financial assurances from the applicant to ensure successful wetland replacement.

Wetland Banking consists of pre-established replacement wetlands that are deposited into the state wetland banking system as wetland replacement banking credits. Replacement credits are then sold to applicants proposing an LGU approved activity that requires wetland replacement. The sale price of banking credit is negotiated between the buyer and seller, so prices vary throughout the state. Wetland Banking Service Areas have been established to ensure that banking credits are used to mitigate for local wetland impacts. Information on  established and using wetland banks.
