A STICK IN THE MUD: U.S. COAST GUARD, SLIP 36 DREDGING AND REBUILD, SEATTLE, WASHINGTON

摘要

A construction project on the Seattle Washington waterfront during the fall 2004 dredging season succeeded as a result of the willingness of the project proponent, the US Coast Guard, to work collaboratively with state and federal agencies when the project didn't proceed as planned. The project, involving dredging of both clean and contaminated sediments and replacement of a creosote-treated pier, also illustrated the Dredged Material Management Program's ability to adapt to new technical and management challenges, and offers several lessons for dredgers, consultants, and regulators. This project demonstrates several lessons including: understanding and improving upon the limits of existing testing methods; how to address unanticipated contamination; the importance of monitoring the dredging process; and the significant advantages of collaborative interagency relationships.
