The Port of Tacoma (Port) and the Northwest Seaport Alliance (NWSA) are working in collaboration with the US Army Corps of Engineers (USACE) to modernize the Blair Waterway and container terminal facilities by deepening the federal navigation channel and terminal berthing areas to accommodate larger container vessels. The Port, NWSA, and USACE are also exploring the beneficial use of dredged material for nearshore habitat improvements at the East Commencement Bay Habitat Opportunity (ECHO) site and other locations within Commencement Bay. Sediment characterization will determine the suitability of dredged material for in-water or upland reuse, in-water disposal, or upland disposal. This paper discusses project complexities such as design and construction sequencing and stakeholder and tenant coordination to ensure successful implementation. The paper also outlines the design and sediment management approach, highlighting challenges and mitigation measures.
