The USACE proposes partial cost reimbursement to the City of Duluth, pursuant to Section 569 of the Water Resources Development Act of 1999, Public Law 106-53, as amended. The cost reimbursement would be applied to the tentatively selected plan, which consists of the diversion and treatment of collected roadside stormwater. The roadside stormwater would be diverted to the Hartley Park Natural Area and treated through an underground sedimentation vault near the road, followed by a dual-purpose wet sedimentation and flood storage basin with the eastern portion providing sediment storage in the deep pond and the western portion constructed as a filtering wetland. A series of terraced biofiltration basins designed to treat and filter the stormwater will be constructed with the final outlet as a diffused discharge prior to entry to a tributary to Tischer Creek, a cold water trout stream.

The tentatively chosen alternative will consist of excavating critical dunes to create access routes and work and storage areas to remove and replace a concrete walkway. The selected alternative includes 3,000 cubic yards (cyds) of excavated dune sand. The excavated sand will be placed west of the project site along the Lake Michigan shoreline. The proposed project will also include removal and replacement of the existing walkway and grouted stone impacting a 7.5ft wide by 2,300ft long area. The new walkway will include seven curb openings with 20ft-by-20ft turnabouts. The proposed project will also include a temporary access route along the walkway with an average width of 16ft and a maximum width of 24ft. Three (3) work and storage areas with dimensions of 70 feet wide by 150ft long and access and storage areas in the existing parking lot and along the existing concrete walkways. The work period is expected to begin in Summer 2024 and last a full construction season.
