Sea-Tac Airport Impact Study


The 2018 Washington State Legislature adopted an operating budget requiring the Department of Commerce to contract for a study of the SeaTac International Airport. This comprehensive study needs to document the current and on-going effects of the operations of the airport. The study must be submitted to the Legislature by June 1, 2020.

The area for the study is the SeaTac, Burien, Des Moines, Federal Way, Normandy Park, and Tukwila. Meeting the requirements of the budget, these cities have provided a combined $300,000 in order to access $300,000 of state funds.

Commerce established an on-going Technical Advisory Committee to provide input on the consultant selection process. The Committee represents the cities of SeatTac, Des Moines, Federal Way and Tukwila. Each city is represented by two individuals: one who is city staff and one public representative. The Port of Seattle is also a member of the Committee.

Commerce conducted a public information session on November 6, 2019 hosted by the City of Burien. Below are a summary of the session and the presentations made by Stantec.
