Abstract: Design of the homeporting facilities at Everett, Washington, began in 1985. The U.S. Navy and the design team were faced with many challenges, including a waterfront site containing contaminated sediments and deep marine silts to support the pier and wharf structures. As the planning and design evolved, so did the discussions with the regulatory and resource agencies. Major changes in the development for the waterfront facilities occurred in the project as a result of the interaction between the Navy and the regulatory and resource agencies. Construction began in the fall of 1989 of two major waterfront structures, the Carrier Pier 1680 feet long by 126 feet wide (512.1 m by 38.4 m) and the South Wharf 470 feet long by 144 feet wide (143.3 m by 43.9 m). Also included in the project was approximately 1 million cubic yards (764,555 m3) of dredging and disposal of clean sediments. These projects were completed by March 1992. The paper will describe the berthing facilities, pile test program, and construction challenges presented by the difficult site conditions.
