The study determined the need for and feasibility of improving the safety and efficiency of deep-draft water in Grays Harbor, Washington. Features of the tentatively recommended plan include the following: (1) 24.3 miles of channel improvement form the outer bar through the harbor entrance and estuary past the city of Aberdeen and up the Chehalis River to the town of Cosmopolis (Authorized chanel depth would range from 46 feet at the outer bar and entrance to 38 feet through the estuary to Port of Grays Harbor terminals at Aberdeen and 36 feet above port terminals to Cosmopolis); (2) Replacement of the Union Pacific Railrod (UPRR) bridge at Aberdeen; (3) Construction of three turning basins (Hoquiam, Cow Point-Aberdeen, Elliott Slough above UPRR Bridge); (4) Mitigation of 4 acres of lost shallow water fish feeding habitat; (5) Mitigation through dredge modification to avoid increased juvenile and adult crab mortalities from dredging; (6) Improved aids to navigation; (7) Open-water disposal of dredged material at the harbor entrance (Point Chehalis and South Jetty sites) and in the ocean (about 3 1/2 miles from the harbor entrance).
