Highway 23 Wetland Mitigation Bank
The sponsor, the Minnesota Board of Water and Soil Resources (BWSR), is proposing to develop the Highway 23 LGRWRP Bank. The proposed bank site is approximately 113.3 acres in size. The project objective is to restore natural habitat consisting of a depressional and sloped wetland system of shallow marsh, fresh wet meadow wetlands, and native upland prairie to generate an estimated 51.625 wetland banking credits. The site is currently in agricultural production and is subject to drainage by private tile. The sponsor proposes to restore wetland hydrology by disabling the subsurface drainage system and re-establishing native vegetation by seeding and managing invasive species.
