Patriot to Dredge Grays Harbor
- Business & Finance
Tacoma-based American Construction Co. is scheduled to begin annual maintenance dredging of the federal navigation channel in Grays Harbor Inner Harbor by July 25.
The company will dredge up to 500,000 cubic yards of material in the inner harbor near Aberdeen, Washington, working through September 30.
American’s Patriot dredge will place material at the existing South Jetty nourishment site and Washington State Department of Natural Resources-managed Point Chehalis open water disposal site.
Inner harbor dredging is confined to the currently maintained -36 feet mean lower low water, or MLLW, depth. As part of the Grays Harbor Navigation Improvement Project, a contract to dredge to the fully authorized -38 feet MLLW, is currently out for bid.
Corps officials expect to begin the next round of dredging operations in October, including the authorized additional two feet, in the vicinity of South Reach upstream to Cow Point Reach where the Port of Grays Harbor Terminal 4 is located.
