    Appendix H: Land Use Technical Report

    This Land Use Technical Report, prepared for the Port of Seattle's Sustainable Airport Master Plan Near-Term Projects, examines how proposed improvements at Seattle-Tacoma International Airport align with land use plans and regulations in surrounding communities including SeaTac, Des Moines, Burien, and Tukwila.

    Des Moines Creek Business Park West Master Plan – Hearing Examiner Review

    The Des Moines, WA City Council considered a staff recommendation to transfer review of the Des Moines Creek Business Park West Master Plan (LUA2022-0044) from the Council to the city's Hearing Examiner. The proposed 30-acre development near South 216th Street would include a 402,380-square-foot industrial building and requires complex environmental review, including a variance to fill ravine sidewalls and potentially realign a stream. Due to the technical complexity of the land use and environmental issues involved, staff and the City Attorney recommended consolidating the Master Plan review with the required variance before the Hearing Examiner.

    F.A.A. density guidelines: North Sea-Tac Park

    This document presents FAA density guidelines for the North Sea-Tac Park area near Seattle-Tacoma International Airport, showing recommended population limits per acre across different zones. Areas closest to the runway are designated as a 'Clear Zone' allowing only 1.5 people per acre, while an 'Extended Clear Zone' permits 2 people per acre, and surrounding residential areas are limited to 20–40 people per acre. A gymnasium on the map is noted as accommodating 60 people during games, illustrating how the guidelines account for concentrated gatherings near airport flight paths.

    Aircraft noise environment and land use issues near Sea-Tac Airport

    This document outlines several key challenges related to aircraft noise near Seattle-Tacoma (Sea-Tac) Airport. It notes that existing noise measurement systems lack the precision needed by planners, residents, and courts, while federal FAA funds cannot be used to purchase noise-affected lands unless they serve specific airport purposes. Additional concerns include restricted HUD/VA mortgage financing in high-noise areas, the potential negative impact on local tax bases if the Port of Seattle acquires large amounts of noise-sensitive land, and widespread property owner anxiety over declining home values and marketability.

  • FAA Reauthorization 2023: Community Use Of Airport Land

    Like many agencies of the Federal Government, the law giving life to the FAA needs to be reauthorized periodically. The last bill was in 2018 and the current version will be passed this year. A reauthorization bill is something of a misnomer. The first page reauthorizes the agency; the remaining hundreds and hundreds of pages

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.

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.
