Design Features of the Elliott Bay Marina

by Jeffrey A. Layton, Layton & Sell Inc, Redmond, WA, USA,



Document Type: Proceeding Paper

Part of: Coastal Zone '87

Abstract:

The paper presents a summary of the major coastal engineering design features of a new Puget Sound small craft harbor proposed for construction within the City of Seattle. The 1,200 berth marina will occupy a water area of approximately 80 acres. The marina's primary wave protection will be provided by a rubblemound breakwater located along the project's southern boundary. Vertical wall breakwaters will provide secondary wave protection along the east and west boundaries. A 10-acre fill over intertidal shoreline areas will also be provided to create new land for the support of upland marina facilities. In addition, an extensive intertidal mitigation program has been incorporated into the project design to offset environmental impacts due to dredging and filling.
