TagSustainable Airport Master Plan(106)

A public meeting was held on September 10, 2018, at Highline Community College to allow Des Moines residents to weigh in on the Port of Seattle's Sustainable Airport Master Plan (SAMP), which outlines Sea-Tac Airport's growth strategy through 2027. The plan proposes removing limits on Third Runway use and adding 80,000 more annual flights on top of the existing 416,000, raising community concerns about noise, health risks, property values, and environmental justice. Residents were urged to attend and submit comments before the scoping period closed on September 28, 2018.

Port of Seattle presentation outlining the Sustainable Airport Master Plan (SAMP) long-term vision with concurrent strategies to serve market demand. Shows current projects for 46.9M passengers, near-term projects targeting 56M passengers by 2027, and long-term vision for demand beyond 2027 including additional planning and environmental review requirements.

This February 2018 briefing presents an update to the Sustainable Airport Master Plan (SAMP) for Seattle-Tacoma International Airport, outlining both near-term improvement projects and a long-term development vision for the airport. The plan addresses existing conditions, development constraints, and key functional areas—including terminal, cargo, and displaced facilities—while also covering environmental review and stakeholder engagement processes. A phased approach guides how the airport intends to manage growth and infrastructure changes over time.

The Port of Seattle's February 2018 briefing updates the Commission on the Sustainable Airport Master Plan (SAMP), a long-range planning effort initiated in 2013 to identify facility improvements needed at Seattle-Tacoma International Airport over a 20-year horizon. The plan proposes a package of near-term projects—including 19 gates connected to a new terminal north of the existing complex—projected to meet capacity needs through 2027, while keeping the airport's current three-runway system in place. Public scoping for environmental review of these near-term projects was anticipated to begin in mid-to-late 2018.

In a June 21, 2017 letter to the Port of Seattle, the City of Des Moines raised concerns about the SEPA Determination of Nonsignificance for the Concourse D Hardstand Holdroom project at Sea-Tac Airport, questioning whether the facility was truly limited to serving existing passenger levels or was also intended to support future growth. The city argued that the DNS should clarify how the project relates to the Sustainable Airport Master Plan and future expansion. Des Moines emphasized that its residents already bear disproportionate noise and health impacts from airport operations and requested thorough environmental analysis and appropriate mitigation for any airport facility enhancements.
