The Grays Harbor dredging program started yesterday on the federal navigation channel, according to the U.S. Army Corps of Engineers, Seattle District.
The main goal of this cleanup scheme is to remove sediment accumulated since the last maintenance dredging.
This deepening work will also improve deep-draft vessel navigation in the Grays Harbor channel by reducing tidal delays and tidally related draft restrictions to Port tenants.
The USACE, Seattle District, awarded a $27.1 million dredging contract to American Construction Company for combined deepening and maintenance dredging of the Grays Harbor Inner Harbor federal navigation channel.
During the project, approximately 3.5 million cubic yards of material will be removed from the mentioned areas.
The contract contains three distinct work windows: October 1, 2016 – February 14, 2017; July 16, 2017 – February 14, 2018; and July 16 – September 30, 2018.
