In September 2012, the Port of Seattle Commission considered a $6 million request to create a new Sustainability Master Plan (SMP) for Seattle-Tacoma International Airport, replacing an outdated 15-year-old plan. The update was driven by nearly 50% passenger growth since the last plan, rising capacity pressures on roadways, terminals, and taxiways, and the need to meet FAA requirements for federal grants and environmental permits. The SMP aimed to guide long-term airport development through 2015, balancing future growth with sustainability goals within the airport's existing footprint.

This January 2002 Revised Draft Environmental Impact Statement evaluates proposed improvements to SR 509 and I-5 in southwest King County, Washington, including a freeway extension to enhance southern access to Seattle-Tacoma International Airport. The study, prepared jointly by the Federal Highway Administration, WSDOT, Port of Seattle, King County, and the Cities of SeaTac and Des Moines, examines three build alternatives and a no-action alternative, differing in their proximity to Des Moines Creek Park and the airport runway protection zone. The proposed SR 509 extension corridor would be a minimum of 200 feet wide to accommodate general purpose and high-occupancy vehicle lanes in each direction.

The City of SeaTac conducted an environmental review of the Des Moines Creek Basin Restoration Projects, a multi-agency effort involving the cities of SeaTac and Des Moines, the Port of Seattle, and King County. The project aims to improve water quality, reduce flooding, and restore fish habitat along Des Moines Creek by building a new detention facility, installing a high-flow bypass pipe, and maintaining low-flow water levels during dry summer months. The city's staff determined that the project does not require a full Environmental Impact Statement, as it is not expected to have a significant adverse impact on the environment.

This document presents evidence that the Port of Seattle violated Federal Grant Assurance C.6 and Washington State law RCW 53.54.020 in connection with its FAR Part 150 Noise Compatibility Program at Seattle-Tacoma International Airport. It compiles 17 items of supporting evidence, including a 1998 congressional request for a GAO audit, state auditor correspondence, findings by Deloitte & Touche identifying violations from 1990 to 1994, and records showing the Port received over $100 million in federal funds tied to noise mitigation commitments it allegedly failed to honor. The materials illustrate the consequences for surrounding communities and governments that held land-use authority under the noise compatibility planning process.

In March 1996, an Expert Arbitration Panel reviewed whether the Port of Seattle had met noise reduction requirements set by the Puget Sound Regional Council as a condition for approving a third runway at Sea-Tac International Airport. A majority of the Panel concluded that, despite the Port's extensive noise abatement programs, it had not demonstrated a sufficient reduction in real, on-the-ground noise impacts to satisfy Resolution A-93-03. This decision left the noise condition as the sole remaining hurdle for authorizing the third runway's construction.

Resolution No. 3212, adopted by the Port of Seattle in 1996, approved the construction of a new third runway at Seattle-Tacoma International Airport (Sea-Tac) to address growing air traffic demand and reduce delays caused by poor weather conditions. The resolution followed years of regional studies, environmental impact reviews, and public involvement, including findings that no feasible alternative airport sites existed in the four-county area. It also committed the Port to fulfilling additional noise reduction measures as required by Puget Sound Regional Council Resolution A-96-02.

In November 1983, the Port of Seattle sent this letter and attached survey summary to attendees of neighborhood workshops held near Jackson International Airport (Sea-Tac), informing them of community attitude surveys conducted by McClure Research Company on aircraft noise concerns. The surveys gathered resident opinions on potential noise remedy programs—including purchase guarantees, noise insulation cost-sharing, and avigation easements—to help planners assess program feasibility and likely participation rates. Results showed that workshop attendees' concerns closely mirrored those of the broader affected community living in areas with noise levels of 70 Ldn and above.

Letter from Port of Seattle Director of Aviation Oris Dunham to King County Council Chairman Paul Barden regarding a Memo of Understanding for Boeing Headquarters project at Sea-Tac International Airport. Includes discussion of rezoning approval following favorable Washington State Supreme Court ruling.

In December 1979, the King County Council passed Motion 4668 approving a rezone request by the Port of Seattle (Building and Land Development File No. 224-78-R), subject to conditions including the Port providing 5 acres for a neighborhood park and agreeing not to develop a 55-acre Westside Greenbelt buffer area for ten years. In May 1981, the Council proposed Motion 81-322 to rescind and replace Motion 4668, with key differences in the conditions outlined on page 2 of each motion. The matter, which had been appealed by both the applicant and neighboring property owners, required a separate public hearing in affected communities as part of the site plan approval process.
