The cities of Burien, Des Moines, Normandy Park, and SeaTac entered into a formal interlocal agreement to coordinate their review of the Port of Seattle's Sustainable Airport Master Plan (SAMP), which outlines airport growth over the next 20 years. The agreement establishes a shared process for hiring and funding consultants, issuing joint comment letters, and responding to environmental documents produced under NEPA and SEPA. Contract administration is led by the City of SeaTac, while fiscal management is handled by the City of Burien.

This 2017 technical memorandum, prepared by Leigh Fisher for the Port of Seattle, outlines development alternatives for Seattle-Tacoma International Airport as part of a Sustainable Airport Master Plan. It covers proposed changes to the airfield, passenger terminals, ground access, parking, air cargo facilities, and general aviation. The document evaluates options such as runway relocations, new taxiway configurations, and terminal expansions to address capacity, safety compliance, and long-term growth needs.

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.

This 2017 technical memorandum, prepared by Leigh Fisher for the Port of Seattle, outlines facility requirements for Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan. It covers planned needs across airfield operations, passenger terminals, ground access and parking, air cargo, and general aviation based on projected activity levels. The document provides detailed assessments of existing infrastructure and identifies future capacity and design requirements to accommodate long-term growth at Sea-Tac.

This September 2015 technical report, prepared by Leigh Fisher for the Port of Seattle, provides long-range forecasts of aviation activity at Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan. It examines historical and projected trends in enplaned passengers, air cargo, and aircraft operations, drawing on regional socioeconomic data such as population growth, employment, and income in the Seattle-Tacoma area. The forecasts are intended to support future airport planning decisions, including infrastructure and capacity needs.

This July 2015 technical memorandum outlines the background, goals, and objectives for Seattle-Tacoma International Airport's Sustainable Airport Master Plan (SAMP), prepared by Leigh Fisher for the Port of Seattle. It describes how the SAMP differs from a traditional airport master plan by integrating financial, environmental, and community sustainability considerations into long-term airport development planning. The document also explains how sustainability goals—drawn from national, regional, and Port of Seattle policies—will be used to evaluate and screen future development alternatives for Sea-Tac Airport.
