Maintenance dredging of the upper and lower channel of the Everett Harbor and Snohomish River’s upper and lower channel is expected to be completed by the end of this month.
The $1.5 million project, which began November 18, is being done by Portable Hydraulic Dredging, LLC. of Anchorage, Alaska.
The work involves removal of around 100,000 cubic yards of material from the upper channel and 40,000 cubic yards from the lower one. The dredged material is being beneficially placed on Jetty Island’s west shore.
Prior to dredging, the material was tested and the Corps prepared a biological evaluation in accordance with the Endangered Species Act.
The port-owned Jetty Island is a man-made island composed of sediment dredged from the Snohomish River. It began as a riprap jetty in the late 1800s and provided a protected harbor and navigation channel. The Port of Everett gained ownership of Jetty Island in 1929 and, with the help of the U.S. Army Corps of Engineers, built a new marsh of dredged river materials in 1989.
