Grand Island National Recreation Area Dredging

This project on the Hiawatha National Forest is for annual dredging at Williams and Powell Point Landings for access to and from Grand Island National Recreation Area near Munising, Michigan. The work may be completed after ice-out, but no later than May 21st, 2022. The work includes removal of not to exceed 300 cubic yards of drift sand to maintain sufficient depth at Powell Point and the removal of not to exceed 1000 cu. yds. of drift sand at Williams Landing docks for barge operations to and from Grand Island National Recreation Area. Dredge an area 30 ft. wide by 70 ft. long (parallel to thepiers) at Powell Point and William's Landing barge ramp areas to a depth of six feet below surface water elevation. Additionally, the passenger ferry areas may be dredged to an area 40 ft. wide by 30 ft. long as determined by the US Forest Service. Spoils from each location need be placed in an approved upland location for dewatering. Dredge spoils must be immediately stabilized (ex. silt fence) for dewatering. The contractor needs to move all spoils to the approved upland disposal sites within 30 days of dredging. The spoils that are dredged from Williams Landing need to be hauled to the approved dredging spoil storage locations (see map in contract solicitation package), pushed into piles no less than 13 feet high and no more than 15 feet high, and the dredging spoils need to be consolidated accordingly to maximize the space within the two approved storage locations. Haul material from Powell Point to Paulson Pit or other location approved by US Forest Service.
