Construction is anticipated to vary widely across the project limits. The applicant requests authorization to excavate 0.65 acres (2,405 linear feet) of the Minnesota River and requested authorization for temporary disturbance of 3.36 acres (2,783 linear feet) of the Minnesota River for construction of the bank grading. In the area east of the Highway 101 bridge to the historic marina, significant bank grading will help to bring the riverbank to a more stable slope to manage continuous bank erosion. Slopes will be graded from nearly vertical, incised banks to gentler, flatter slopes (3:1 and 4:1) using grading equipment operated from the land side of the river. The bank will be stabilized with riprap up to the 2-year flood elevation, then transition into a “soft armoring” approach to the 5-year flood elevation. No “soft armoring” will be below the OWHM for USACE review.
For the marina area of the project, the proposed project would result in the permanent discharge of fill in 0.01 acres fresh wet meadow wetland and the excavation of 1.30 acres of open water. The marina is currently shallow for small watercraft users, and the channel is extremely narrow and unpassable. The proposed project would restore the historic marina by making reconnecting the marina to the river, performing grading and dredging to support operational use, and ultimately bringing people to the river.
