St. Paul District of the U.S. Army Corps of Engineers (Corps) has received an application for a Department of the Army permit pursuant to Section 404 of the Clean Water Act (33U.S.C. §1344). The project would affect waters of the United States associated with Muskego Creek.

The proposal is to add a 10.36-acre parcel directly east of the existing 35.36-acre RFD II Mitigation Bank Site. The bank site was initially approved on November 20, 2020, and modified on June 5, 2024. The overall objective of the initial bank project was to restore wetlands and upland buffer to generate approximately 25.29 wetland credits as a source of mitigation for impacts authorized by state and federal regulatory programs. Specific objectives of the initial bank project included restoring wetland hydrology to effectively drained wetlands by disabling subsurface drain tiles, re-establishing wetland and upland communities with native, non-invasive plant communities, and improving the water quality, stormwater attenuation, groundwater recharge, and habitat functions of the site.
The objective for the new parcel, identified as “Phase II”, will be to restore native vegetation to both wetland and upland plant communities to generate approximately 5.57 additional wetland credits. Vegetative restoration would require removal of the herbaceous layer and weedy/invasive shrubs and trees and seeding with native wetland seed mix. The wetland within Phase II is part of a contiguous wetland complex that may have been previously influenced by the hydrology restoration that was completed for the initial bank site.

The applicant is requesting a DA permit to remove the existing Millpond Dam and restore approximately 1,200 linear feet of stream channel to
reconnect high-quality cold-water habitat. The entire above-ground portion of the dam would be dismantled and removed from the site, and any subsurface footings or structural remnants would be excavated to a verified elevation below the proposed restored streambed to ensure they do not interfere with channel function. The regulated activities associated with the proposed project includes the permanent discharge of dredged and fill material into 700 square feet below the plane of the Ordinary High Water Mark of the Millpond for the purpose of removing a dam to improve stream connectivity and the permanent discharge of dredged and fill material into 7.09 acres below the plane of the Ordinary High Water Mark of the Millpond, along approximately 1,200 linear feet, for the purpose of stream restoration.

The sponsor is proposing to restore and enhance 39 acres of sedge meadow/wet prairie, 18.8 acres of shallow marsh, 7 acres of deep marsh, and 14 acres of shrub-carr wetland communities on approximately 102 acres of land within the proposed Lower Sugar River Wetland Mitigation Bank site. The site has been partially drained by ditches and a tile system and is currently in an agricultural use. The sponsor proposes to disable the tile system and remove a berm to restore hydrology and establish native vegetation in all upland and wetland communities.
