Book Description
The need for improving the existing federal navigation channels in the East, West, and Duwamish Waterways at Seattle, Washington is reported. Continued growth in waterborne commerce is forecast for Seattle Harbor for 1990 to 2000. Existing safety problems and the need for more efficient water transport will intensify. The Recommended Plan would increase the authorized depth of the East and West Waterways from 34 feet to 39 feet. The existing deep-draft channel in the Duwamish Waterways would be enlarged from 30 feet deep by 200 feet wide to 39 feet deep by 250 feet wide. An existing railroad bridge restricting channel clearance to 145 feet wide would be replaced with a bridge allowing 250-foot channel clearance. (In a separate project by the city of Seattle, two highway bridges restricting navigation are being replaced.) These improvements would enable large cost efficient vessels to navigate the deep draft channel more fully loaded, with less tidal delay, and with less tug assistance, resulting in transportation savings and improved safety. The project-related loss of 4 acres of shallow-water/intertidal salmon habitat wold be mitigated by construction of replacement habitat in the upper Duwamish Waterway. Two acres of additional shallow-water habitat would be constructed as fishery enhancement. The Port of Seattle would be local sponsor for channel enlargement, mitigation, and for a public access boat ramp added in response to expressed public interest. The Muckleshoot Indian Tribe, which has treaty fishing rights in the Duwamish River, would sponsor fishery enhancement.

Book Description
As part of the study on the Duwamish River Navigation Improvement Project, this literature search was performed to compile and review all existing information and ongoing research on lands and natural resources that may be affected during the widening and deepening of the Duwamish Waterway. The area of interest included Seattle Harbor, Elliott Bay, the Duwamish River and Waterway, and the Duwamish-Green River system to Howard A. Hanson Dam. Major information topics covered in the literature search include land use and development plans in the Lower Duwamish River and Seattle Harbor and water quality and aquatic resources upstream to Howard A. Hanson Dam. Coordination with Federal, state and local government agencies allowed access to existing libraries and bibliographies on the study area. Unpublished information on file was accessed when available and current research activities were surveyed. City, University, and consultants' libraries were other major sources of literature.
