Milwaukee, Wisconsin -- Project Description and Background
Commercial harbor with project depths of 30 feet in the approach, 28 feet in the entrance channel, 27 feet in a major portion of the south basin, and 21 feet in the north basin. Over 21,000 feet of structures including breakwaters, piers, and revetments.
Breakwater repairs are required; deterioration of the timber and loss of fill stone created holes in the structure allowing waves and sediment to flow through the structure into the navigation channel.
30,000-40,000 CY are dredged on a 3-to-4-year basis
Current Status
Design for the repair of the breakwater at various sections of the structure is underway. A construction contract is scheduled for award by January 2024.
Plans and specifications are under development to dredge 30,000-40,000 cubic yards at the entrance channel to an authorized depth of 28 feet. Contract award is scheduled for May 2024.
Regular O&M repairs are made annually by the floating plant.
