Project Name: Blair Waterway Berth Maintenance Dredge: Husky and Washington United Terminals

Description of proposal: The Port of Tacoma (Port) proposes to perform maintenance dredging of ship berths at the Port’s Husky and Washington United Terminals on the Blair Waterway to restore the authorized depth of -51 ft Mean Lower Low Water (MLLW). The total estimated dredge volume is 27,000 cubic yards including an incidental 1-foot over dredge allowance (-52 ft MLLW). The dredge material will be sampled and characterized by the Port and the Dredge Material Management Program (DMMP) to determine disposal location. Suitable dredge material will be placed at the Commencement Bay open water dredged material site. Unsuitable material will be placed at an approved upland site. Preliminary data suggest all material is eligible for open water disposal. There is no proposed change of use.
