177.84 KB Puget sound gateway program – phase 1 of the sr 509 completion project environmental re evaluation page 342 1 This January 2018 environmental re-evaluation examines the potential impacts of Phase 1 of the SR 509 Completion Project, part of the Puget Sound Gateway Program, prepared for the Federal Highway Administration and Washington State Department of Transportation. The document assesses changed conditions and effects across multiple environmental categories—including noise, air quality, water quality, wetlands, and transportation—comparing the current project phase against the 2003 Final Environmental Impact Statement's preferred alternative. Notably, the noise section evaluates both operational and construction-phase sound impacts on surrounding communities, making it a relevant reference for research into transportation-related noise policy near Sea-Tac Airport. -

358.54 KB 2024 draft 4 cities ea comment letter to port of seattle Four cities neighboring Seattle-Tacoma International Airport — Burien, Normandy Park, SeaTac, and Des Moines — submitted formal comments on the airport's Sustainable Airport Master Plan Environmental Assessment, raising concerns about aircraft noise, air quality, and community health impacts. The letter argues that standard noise metrics like DNL 65 dBA fail to capture residents' real experiences, and calls for supplemental noise measurements, expanded sound insulation programs, and broader mitigation efforts beyond current regulatory thresholds. The cities urge the Port of Seattle to collaborate directly with local communities throughout the environmental review process to ensure that airport growth does not disproportionately burden adjacent neighborhoods. -
159.94 KB 2025.11.21 draft petition for review sea SAMP three cities Three Washington cities — Burien, Des Moines, and SeaTac — have filed a legal challenge in the Ninth Circuit Court of Appeals against the Federal Aviation Administration's September 2025 decision approving near-term expansion projects at Seattle-Tacoma International Airport. The petition contests the FAA's Finding of Significant Impact/Record of Decision related to the airport's Sustainable Airport Master Plan, which the cities argue warrants judicial review. The filing, submitted November 21, 2025, was made within the 60-day statutory deadline under federal aviation law. -

The amendment updates Paragraph 7 to clarify that contract management responsibilities — including consultant oversight, invoice coordination, and meeting arrangements — shall be administered by the City of Des Moines. All other terms of the original agreement remain unchanged, and the amendment was signed by authorized representatives of all four cities in 2020. -
2026-08-30 2.93 MB 29 pp. Appendix C Aircraft Noise This document explains the fundamentals of aircraft noise at Seattle-Tacoma International Airport, covering how sound is measured in decibels and A-weighted decibels (dBA) to reflect human hearing sensitivity. It describes how outdoor sound levels decrease with distance due to wave spreading and atmospheric absorption, with noise typically dropping 6 dB each time the distance from the source doubles. A comparative chart of common indoor and outdoor noise levels is included to help put aircraft noise levels in everyday context. -
2026-08-30 2.30 MB 8 pp. Appendix D Land Use This document describes existing land uses near Seattle-Tacoma International Airport (SEA) as part of a Part 150 noise study. It draws on King County parcel and assessor data to categorize land use across nearby communities including Burien, Des Moines, Federal Way, Normandy Park, SeaTac, Tukwila, and unincorporated King County. The City of Burien, for example, is predominantly single-family residential (about 70% of its land area), with smaller shares dedicated to open space, commercial development, and institutional uses. -
2026-08-30 14.39 MB 124 pp. Appendix E Consultation and Correspondence Appendix E of the Seattle-Tacoma International Airport Part 150 Study documents the consultation and correspondence process, including meetings of a Technical Review Committee (TRC) held between 2024 and 2025, briefings for local jurisdictions such as Tukwila, Burien, Des Moines, SeaTac, and King County, and a Stakeholder Advisory Roundtable briefing. The TRC, established by the Port of Seattle, brought together key community and organizational representatives to provide technical input on aircraft noise levels and land use impacts under federal guidelines. While the TRC advised on the study, final decision-making authority remained with the Port of Seattle, with the FAA responsible for approving Noise Exposure Maps and the Noise Compatibility Program. -
2026-08-30 20.57 MB 323 pp. Appendix G Comments and Responses This document is Appendix G of the Seattle-Tacoma International Airport Part 150 Noise Study, compiling public comments and official responses gathered during the study's development. It covers a wide range of topics organized into three main areas: Part 150 regulations and noise exposure maps (including noise metrics, flight tracks, and FAA guidelines), current airport operations and community concerns (such as flight paths, nighttime operations, and the sound insulation program), and miscellaneous issues like health effects, air quality, and property values. Comments were collected through multiple channels including public open houses, workshops, the study website, and email.
