A July 23, 2019 Port of Seattle briefing document outlines the aviation capital planning and preliminary design process for Sea-Tac Airport, covering three phases: completed master planning, advanced planning still in progress, and preliminary design requiring capital funds approval. Key topics include near-term projects, projects requiring preliminary design authorization, and the relocation of a Glideslope Antenna. The preliminary design phase aims to develop individual project programs in sufficient detail to produce a Project Definition Document (PDD) and transition projects into full design.

The Burien Quiet Skies coalition compiled this 2019 document comparing FAA and Port of Seattle noise abatement commitments against actual progress, revealing decades of unmet promises dating back to 1985. Key concerns include hundreds of homes left uninsulated or poorly insulated, a 12-year gap in required noise modeling data, and noise levels in some Burien neighborhoods now exceeding the 65 dB threshold that triggers mitigation eligibility. The document calls on the FAA to hold the Port of Seattle accountable for failing to implement long-recommended noise reduction measures and for significantly underestimating flight operations and their impact on surrounding communities.

The League of Quiet Skies Voters (LOQSV), a Seahurst, WA-based organization focused on aviation noise and its impacts on health and the environment near Sea-Tac Airport, sent a candidate questionnaire to 2019 election candidates on July 4, 2019. The letter invited candidates to share their positions on aviation expansion, human health, and environmental concerns, with responses to be published before the primary election if submitted by July 19, 2019. LOQSV described itself as an advocate for communities neighboring the 8th busiest airport in the United States.

The South King County Fund (SKCF) was established by the Port of Seattle Commission on November 27, 2018, to provide resources and support to communities surrounding Sea-Tac Airport. The fund designated $750,000 for 2019, with total funding not to exceed $10 million between 2019 and 2023. This presentation by Environmental Engagement Program Manager Andy Gregory outlines the fund's origins, guiding principles, legal spending boundaries, and community outreach plans.

A consulting team addresses two community concerns about Seattle-Tacoma International Airport: the lack of a direct NEPA environmental review covering noise impact growth between 2012 and 2018, and questions about how the airport's third runway is being used. The document explains that while current NEPA and Part 150 processes will capture existing noise conditions, they will not specifically compare 2012 versus 2018 impacts, and that federally funded runways like the third runway must be made available whenever air traffic control deems it necessary. The consultants propose reviewing historical Part 150 studies, past NEPA documents, and third-runway records to assess noise impacts on surrounding communities, while also supporting clients in engaging the Port, FAA, and airlines through the StART committee and other channels.

Seattle-Tacoma International Airport (Sea-Tac), operated by the Port of Seattle, is the eighth busiest U.S. airport, serving 49.8 million passengers and handling over 432,315 metric tons of air cargo in 2018, with 32 airlines offering 91 domestic and 29 international non-stop destinations. The document also profiles Jason Schwartz, an aviation professional with over 25 years of experience specializing in airport noise management, UAS operations, and airside planning, currently serving in dual roles at the Port of Portland and his own consulting firm, Aviation Compatibility Consulting. Schwartz's background includes noise program management, community engagement, and relevant certifications in airport environmental management and business operations.

Delta Air Lines marked its 5-year anniversary of establishing a global hub at Seattle-Tacoma International Airport (Sea-Tac), highlighting growth from 25 to 53 total destinations, a 129% increase in peak-day departures, and 9% lower fares between June 2014 and June 2019. The airline also expanded its workforce from 2,200 to 3,500 Seattle-based employees and invested in a new 450,000 sq. ft. International Arrivals Facility. This period of rapid growth at Sea-Tac is documented alongside FAA Terminal Area Forecast data projecting continued aviation activity increases through 2045, relevant context for understanding long-term noise impacts at the airport.

Seattle-Tacoma International Airport handled 49.8 million passengers and 438,391 aircraft operations in 2018, ranking 8th in the U.S. by passenger volume. A noise compatibility study forecasted total annual aircraft operations to grow from approximately 301,870 in 2009 to 399,200 by 2021, driven by increases in both domestic and international air carrier activity. The airport operates three category IIIb certified runways and is dominated by Alaska Airlines, which carries over 50% of its passengers.
