The Managing Members

The Northwest Seaport Alliance is a Federal Maritime Commission-approved port development authority governed by the Ports of Seattle and Tacoma as equal members, with each port acting through its five elected commissioners.

Each port is governed by five commissioners elected at large by the citizens of their respective counties. They serve four-year terms and establish policy for their Port and the alliance.

The ports remain separate organizations that retain ownership of their respective assets.

The president of the home port commissions serves as co-chairs of The Northwest Seaport Alliance.

The commissioners of the Ports of Seattle and Tacoma in 2014 announced a bold vision: Instead of competing, the two ports would join forces and form an alliance to better compete on a global scale.

The Northwest Seaport Alliance was officially formed in August 2015, following comprehensive public outreach and approval from the Federal Maritime Commission. It marks an unprecedented, historical first in North America.
