The U.S. Army Corps of Engineers (USACE), Seattle District, is initiating an effort to update and revise the Lake Washington Ship Canal (LWSC) Master Plan. The Master Plan update effort follows guidance set forth in Engineer Regulation (ER) and Engineering Pamphlet (EP) 1130-2-540, Natural Resources Stewardship, Chapter 2, and ER/EP 1130-2-550, Project Operations – Recreation Operations and Maintenance Policies, Chapter 3. This project is a coordinated effort involving team members from the LWSC, Environmental and Natural Resources Division, Real Estate, Geospatial Section, and the Planning, Program, and Project Management Division. Estimated duration for this effort is approximately 24 months.
The current Master Plan was approved approximately 20 years ago and must be brought up-to-date. While the overall purpose and running of the Locks and its land has not changed, the Master Plan is a tool for the responsible stewardship of the natural and cultural resources within the area of responsibility of the LWSC. Over the past couple of decades, there have been natural changes to the existing project conditions, the zone of influence, and new special issues and unique concerns identified. The purpose of the Master Plan revision is to reflect the current project conditions and provide the projected future conditions of the project.
