This document contains a series of maps outlining a highlighted geographic zone spanning several Seattle-area neighborhoods, including Glendale, Southern Heights, Boulevard Park, and North SeaTac. The yellow-shaded areas, bordered in red, appear to delineate a specific study or policy boundary likely related to Sea-Tac Airport noise impact zones. Streets and landmarks such as Hamm Creek Natural Area, Des Moines Memorial Drive, and Southern Heights Park are visible within and around the designated boundary.

This document is an aerial map showing the area surrounding Seattle-Tacoma (Sea-Tac) Airport, covering the cities of Des Moines and SeaTac in Washington State. It highlights key roads and boundaries, including Des Moines Memorial Drive S, S 200th Street, 18th Avenue S, and SR 99, with colored overlays likely indicating noise-impact or study zones near the airport. Runway 34R and Angle Lake are visible landmarks, with the map appearing to delineate jurisdictional or noise-contour boundaries relevant to airport planning and policy.

This map shows the Des Moines and SeaTac area of Washington State, highlighting a noise impact corridor (shown in teal) that sweeps across the region near Sea-Tac Airport. The corridor passes over several schools including Mt. Rainier High School, Pacific Middle School, Midway Elementary, St. Philomena School, and Des Moines Elementary, indicating these institutions fall within the airport's noise-affected zone. A separate boundary (shown in orange) outlines what appears to be an airport-related land use or acquisition area in the southern portion of the map near Interstate 5.

In an October 2017 email to Burien City Council members, resident Sharyn Parker critiques a letter from Port of Seattle Chairman Tom Albro defending Sea-Tac Airport's expansion and noise mitigation efforts. She argues that Albro's response fails to address the real-world impacts of rapidly increasing flight operations—including a 9% annual average flight increase—on surrounding communities, and that the Port's noise modeling data is outdated and understates actual activity by 51%. Parker calls on the Council to challenge what she characterizes as the Port's lack of candor and possible intentional underestimation of flight projections to avoid costly noise and air quality mitigation requirements.

In an October 2017 email, Burien Advisory Committee member Sharyn writes to council members Nancy Tosta and Debi Wagner to propose revisions to a draft council resolution concerning Sea-Tac Airport noise and growth. She argues that Sea-Tac's 2013-2018 Part 150 Study severely underestimated actual flight operations by 51%, which has minimized noise mitigation efforts for South King County residents. She calls for updated noise modeling, a reduction in operational levels, and an end to flights over Seahurst, warning that without immediate action, residents could face nearly 1,500 additional flights per day by 2025 with no mitigation relief for another decade.

A Title 14 CFR Part 150 Final Noise Exposure Map Report for JFK International Airport prepared by Environmental Science Associates and other consulting firms for the Port Authority of New York & New Jersey. The report addresses federal aviation noise regulations and mapping requirements.

Final Noise Exposure Map Report for LaGuardia Airport prepared under Title 14 CFR Part 150 by Environmental Science Associates and other consulting firms for the Port Authority of New York & New Jersey. This report addresses federal requirements for airport noise compatibility planning.

These documents contain communications from January 2017 regarding aircraft noise concerns over the Seahurst and White Center neighborhoods near Seattle-Tacoma International Airport. A noise consultant advises that Seahurst likely falls below the FAA's 65 dBA threshold that defines 'noise sensitive areas,' arguing this means an Environmental Assessment (EA) and historic property inventory are not required. Separately, a Burien resident emails city officials sharing research from Sea-Tac's Part 150 Study suggesting that flights over these neighborhoods were anticipated and approved, and that the absence of an EIS may not constitute valid grounds for litigation by the Quieter Skies coalition.

This Federal Aviation Administration (FAA) page outlines the agency's Airport Noise programs, covering two key regulatory frameworks: Airport Noise Compatibility Planning (14 CFR Part 150) and Airport Noise and Access Restrictions (14 CFR Part 161). It provides links to funding summaries, noise exposure maps, planning data by state, and regulatory guidance including advisory circulars on noise control and sound insulation for residences near airports. The page also references the FAA's Land Use Planning Initiative, which offers guidance to airport sponsors and local agencies on improving compatibility between airports and surrounding communities.
