The U.S. Army Corps of Engineers is taking public comment on a project proposal by the Port of Astoria to dredge the West Mooring Basin.
The project involves dredging up to 109,000 cubic yards of accumulated sediment from more than 11 acres within the marina over the next decade. Up to 54,500 cubic yards of accumulated sediment would be dredged during the first year, and up to 54,500 additional cubic yards would be dredged over the remaining nine years.
The dredge depth would range from 6.0 to 17.0 feet of mean lower low water. The Port plans to use a suction dredge operating from a floating barge, disposing of the dredged material in the flow lane of the Columbia River through a submerged pipe.
Comments are due by Sept. 2 and can be emailed to danielle.h.erb@usace.army.mil or mailed to: U.S. Army Corps of Engineers, Regulatory Branch, Danielle Erb, P.O. 2946, Portland, Oregon 97208-2946.
