Mitigation Bank Public Notice Butterfly MeadowsThe Butterfly Meadows Wetland Bank is a proposed mitigation bank project in Anoka County, Minnesota. The project site is approximately 126.2 acres and is currently being used for sod farming. The objective of the project is to restore 72.2 acres of historical wetlands that have been drained by a system of ditches. The restoration will be achieved by filling the ditches and re-establishing the natural hydrology of the area,
which will support the development of diverse wetland habitats including deep and shallow marshes, wet meadows, and hardwood swamps.

RFD II, LLC WETLAND COMPENSATORY MITIGATION BANK PROPOSALThe 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.

Cascade Mill Pond Dam RemovalThe 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.
