  • Seattle residents are flocking to South King County during COVID pandemic

    By Melissa Hellmann Seattle Times staff reporter Jeff Hickey’s three-decade stint in Seattle came to an end last March when the rent on his Queen Anne neighborhood home rose by $300 a month.

    Section 14: Summary — Study of the Current and Ongoing Effects of the Operation of the Seattle-Tacoma International Airport

    A 2020 study evaluated the positive, negative, and neutral effects of Seattle-Tacoma International Airport on six nearby cities — Burien, Des Moines, Federal Way, Normandy Park, SeaTac, and Tukwila — using data spanning 1997 to 2019. The study found that noise was the top public concern, followed closely by air quality issues from aircraft operations, along with traffic congestion and distrust of the FAA and Port of Seattle. Researchers attempted to distinguish between impacts directly caused by airport operations and those resulting from the broader regional population growth that roughly doubled over the same period.

    Section 13: Socio-Economics — Study of the Current and Ongoing Effects of the Operation of the Seattle-Tacoma International Airport

    This 2020 report examines the socio-economic conditions in six south King County cities near Seattle-Tacoma International Airport, including Burien, Des Moines, Federal Way, Normandy Park, SeaTac, and Tukwila. It analyzes demographic trends such as population growth, age distribution, and ethnic profiles from 1997 to 2018, finding that most study area cities grew more slowly than King County overall, with Burien being a notable exception largely due to a 2010 annexation. The report is part of a broader study assessing how airport operations affect surrounding communities across indicators including income, housing, education, employment, and municipal tax revenues.

    Regional air quality briefing: Highline Forum

    A September 2017 regional air quality briefing presented by the Puget Sound Clean Air Agency to the Highline Forum covers air pollution sources, trends in south King County, and efforts to improve air quality in the region. The presentation also introduces an upcoming University of Washington study on ultrafine particle pollution, which is particularly relevant to communities near high-traffic corridors. The agency's vision emphasizes clean and healthy air for all residents regardless of socioeconomic status or location, covering four counties: King, Pierce, Snohomish, and Kitsap.

    Burien Airport Advisory Committee white paper

    A 2017 white paper from Burien's Airport Advisory Committee argues that unchecked expansion at Sea-Tac Airport is causing serious health and environmental harm—including noise pollution, air pollution, and related illnesses—for residents of South King County and parts of Seattle. The committee contends that the Port of Seattle has prioritized the convenience of air travelers over the well-being of nearby communities, while King County taxpayers bear the financial burden of an airport that benefits the entire state. The paper calls on the Burien City Council to urge regional and state leaders to coordinate aviation capacity planning and meaningfully address the human costs of continued airport growth.

    Aerial View of Freeway Interchange Near Puget Sound, South King County

    Aerial photograph showing a multi-lane freeway (likely I-5 or SR-99 in the Sea-Tac/south King County area) with an interchange, surrounding dense conifer forest, low-density residential development, and a small commercial building complex in the foreground. A body of water consistent with Puget Sound is faintly visible in the background, suggesting this location is west of the airport corridor.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

Read This!

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
