The U.S. Army Corps of Engineers (USACE) Seattle District said that the maintenance dredging works at Everett Harbor and Snohomish River will begin around October 16, 2026.
Dredging performed by the contractor, American Construction Co., Inc., is expected to start in the lower settling basin via clamshell dredge and bottom dump barges.
Under the project, approximately 175,000 cubic yards will be dredged. The primary placement site for dredged material will be at Port Gardner, and a secondary site will be in Elliot Bay.
"The federal channel will remain open for waterway users during dredging operations. All dredge work areas, including the navigation channel and target placement sites, will be used by the contractor during dredging operations," USACE said in its official statement.
Dredging work will be performed continuously 24/7 for approximately 60 days, with all work concluded no later than February 14, 2027.
