Welcome to the Terminal 5 Improvements Project online open house.

The Port of Seattle, acting as the State Environmental Policy Act (SEPA) Lead Agency, conducted an environmental review of proposed changes to Terminal 5. The review is documented in an Environmental Impact Statement (EIS). The project proponents are the Port of Seattle and the Northwest Seaport Alliance (NWSA), a marine cargo partnership between the Port of Seattle and the Port of Tacoma.

A Draft EIS was released in May 2016 for the community’s review and comment. The comment period closed in July. To view all comments submitted during the Draft EIS comment period and the earlier scoping phase, please visit the Library page. The Port of Seattle reviewed and provided responses to all comments received during the Draft EIS public comment period in the Final EIS. The Final EIS (Volumes 1 and 2) was released on October 18, 2016.
