Mississippi River Upper Pool 4 Islands
The Corps initiated a feasibility study in 2017 to identify steps that could be taken to improve the habitat in Upper Lake Pepin, particularly in Catherine Pass. These measures include islands, water level management structures, overwintering dredging and shoreline protection. The proposed solutions are designed to work together to reduce sediment and increase water clarity within the area. The features include constructing four islands, refuge dredging, a water level management dike and control structure, an access road, two backwater dredged areas, three areas of shoreline protection, a mudflat, access dredging and a partial closure of Catherine cut.

Lock and Dam 4 End Cell draft EA
The purpose of this project is to construct an end cell just below the existing lower guidewall at Lock and Dam 4, near Alma, Wisconsin. The project would increase the protection from barge impacts and reduce operability issues. The end cell would be 33 feet in diameter and be connected to the existing guidewall via an expansion joint, providing a smooth transition between end cell and wall. The end cell would increase the longevity of the lower guidewall of Lock and Dam 4.

2011-05382-SJW (Door County, WI) Schneider Pier Construction Project
PUBLIC NOTICE: APPLICATION FOR PERMIT TO perform dredging operations and permanently discharge fill material below the plane of the ordinary high-water mark (OHWM) of Lake Michigan for the construction of a permanent pier structure which would replace an existing breakwater structure. The proposed pier structure would be placed in the exact same location as the existing breakwater feature. However, the dimensions of the newly proposed structure would differ slightly from the existing breakwater structure as rock riprap would be added to the south side of the newly proposed pier structure to prevent damage from wave action. In addition, the project would include the installation of two seasonal floating dock structures, and the construction of a bridge/walkway structure above the plane of the OHWM of Lake Michigan which would extend westward from the shoreline to the newly proposed permanent pier.

2012-05355-MWM (Ozaukee County, WI) City of Mequon Project
PUBLIC NOTICE: APPLICATION FOR PERMIT TO permanently discharge dredged and fill material into 29,911 square feet (0.687 acres) of wetlands for the purpose of constructing three building pads, each 5,000 square feet, and associated grading to support three single family homes. The project intends to provide residential development around a 20-acre man-made pond in the City of Mequon. A total of four approximate 10,000 square foot homes are proposed on the southern side of the pond, each lot is 5 acres in size. Of the four homes proposed, three are proposing wetland fill to construct the building pad to support the home. The building pads are proposed to be constructed in late 2022 and the homes would be constructed in 2023 or 2024.

2019-02869-EMN (Brown County, MN) Mathiowetz Wetland Mitigation Bank
PUBLIC NOTICE: The sponsor is proposing to develop the Mathiowetz Wetland Bank. The proposed bank site is approximately 56 acres in size, including upland buffer areas. The primary objective of the project is to restore wetland hydrology to establish high functioning and self-sustaining fresh wet meadow, shallow marsh, and seasonally flooded basin wetland vegetation communities dominated by native species on approximately 28 acres. The project also would include establishing native grass and forbs (mesic prairie) in approximately 35 acres of upland buffer adjacent to the restored wetlands. Since the site is in a forested floodplain corridor, the objective may also include establishing trees within portions of the seasonally flooded basin and upland buffer areas.

2021-01549-LSP (Marshall County, MN) City of Newfolden Flood Damage Reduction Project
PUBLIC NOTICE: The proposed project is the construction of a flood control impoundment on agricultural land that is currently enrolled in the CRP program. The impoundment will collect runoff water through a ditch system at the northeast corner and discharge the water slowly through a gated outlet structure in the southwest corner. The fill impacts associated with this project are for the construction of a flood control berm, interior and exterior ditch construction with clay liner, and borrow from within the impoundment for construction of the berm.

2021-01546-CCK (Blue Earth County, MN) Medo Wetland Mitigation Bank
PUBLIC NOTICE: The sponsor is proposing to develop the Medo Wetland Bank. The proposed bank site is approximately 71.22 acres in size, including upland buffer areas. Currently the site and surrounding lands are in corn and soybeans agricultural crop production. The objective of the project is to restore hydrology and native vegetation to 12.28 acres of fresh (wet) meadow, 51.71 acres of shallow marsh, and 0.53 acres of deep marsh; which will result in the generation of approximately 61 credits. The Medo bank will fill a need for wetland credits in the minor and major watersheds that serve the growing cities of Mankato and North Mankato.

This public notice amends the previous version that was issued on 20 October 2021. The original project boundary has been adjusted as a result of a finalized ~20-acre land purchase which was added to the southern portion of the bank boundary. The area to be added to the project site is currently used for row crop/agriculture. This land swap will increase the anticipated wetland compensatory mitigation credit total by approximately 12.48 credits (and 8.96 acres of additional buffer).
