WA - Corps of Engineers to Start Grays Harbor Maintenance Dredging
SEATTLE -- The U.S. Army Corps of Engineers will begin maintenance dredging of the federal Grays Harbor Inner Harbor Navigation Channel January 4, 2021.
USACE awarded this three-year dredging contract to HME Construction, which was $4.2 million dollars for the first of three work windows.
Approximately 1.8 million cubic yards of material will be dredged via clamshell dredge from the channel over a period of roughly three years. Roughly 600,000 cubic yards of material is expected to be dredged during each of three separate work windows.
Dredged material will be transported by barge to either the South Jetty or the Pt. Chehalis open water placement sites. The material has been tested, and USACE prepared a biological evaluation and National Environmental Protection Act (NEPA) documentation in accordance with the Federal and State requirements. The Corps assures full environmental compliance prior to starting, and potential impacts are avoided through implementing timing restrictions and dredging best management practices.
