A feasibility report and draft environmental assessment (EA) has been prepared by the United States Army Corps of Engineers for the Tacoma Harbor Navigation Improvement project.
A feasibility cost sharing agreement to study navigational improvements in Tacoma Harbor received a signature between the Port of Tacoma and the Corps in the summer of 2018. The goal of the study was to examine improvements that can be made in the waterway to improve the affordability for larger vessels to travel through the Port.
The draft EA and report have devised a plan to expand the turning basin boundary to a diameter of 1,935 feet, expand the width of the channel from 450 to 865 feet, and deepen the existing channel to a depth of 57 mean lower water. The open-water disposal site at Commencement Bay would receive close to 2.4m cubic yards of dredged material and a facility upland would receive another 392,000 cubic yards of material. Another site would receive about 1.85m cubic yards of material to be used for beneficial purposes.
The documents put together are available for the public to view online, and printing services can also be used to create hard Copies of such reports for public review. The public has until Sunday, February 16 to contact tacomaharbor@usace.army.mil with any comments on them.
