The Northwest Seaport Alliance



The Seattle and Tacoma port commissions plan to form The Northwest Seaport Alliance to unify management of the two ports’ marine cargo terminals and related functions. The two ports will retain existing port commission governance and asset ownership.

The Tacoma and Seattle ports today are the third-largest container gateway in North America, and our marine cargo operations support more than 48,000 jobs. Combining the strengths of the two ports’ marine cargo operations will position our region to address competitive challenges and create new economic opportunities.

Draft final agreement

The draft final agreement outlines The Northwest Seaport Alliance’s governance charter, management and financial structures, a transition plan and business development strategy. The ports will form a port development authority (PDA) to manage the container, breakbulk, auto and some bulk terminals in Seattle and Tacoma.

The two port commissions expect to consider submitting the final agreement to the Federal Maritime Commission (FMC) at a joint public meeting June 5 at Auburn City Hall. The commissioners expect to hire John Wolfe, current Port of Tacoma chief executive officer, as the CEO of the seaport alliance following approval of the agreement.
