    Airport land use compatibility: Incompatible and compatible land uses and types of appropriate action

    This document outlines federal guidelines for managing land use around airports to minimize noise and safety conflicts. It distinguishes between incompatible land uses near airports—such as residential development, schools, hospitals, and churches—and compatible ones like agriculture, parks, and parking facilities. It also describes appropriate actions airport sponsors can take, including developing off-airport land use plans, enacting zoning ordinances, and working with local and regional authorities to restrict development in affected areas.

    Sea-Tac Communities Plan: Airport Vicinity Area and Planning Jurisdictional Area (Section 3.2.1)

    This document describes the planning study area surrounding Seattle-Tacoma (Sea-Tac) Airport, which encompassed the entire Highline School District and portions of the Federal Way and South Central School Districts. The study identified four sub-areas forming an 'airport vicinity' zone — defined as the area of primary airport-community incompatibility — to guide policy and land-use planning. King County holds major planning responsibility for the broader sub-regional area, with the Sea-Tac Communities Plan intended to integrate with the wider Highline Community Plan through post-plan coordination.

Study materials cover community trends, open space, environmental reports, and land use policy guides produced by the Environmental Development Commission and the League of Women Voters.

    Sustainable Aviation Fuel Use at a Washington State International Airport: Regional Air Quality Benefits

    A University of Washington research team examined the air quality benefits of using Sustainable Aviation Fuel (SAF) at a Washington State international airport, covering activity during the year 2024. The report, prepared by the Department of Environmental & Occupational Health Sciences and submitted in December 2025, analyzes how SAF adoption can reduce harmful emissions in the surrounding region. It offers findings relevant to policymakers, airport operators, and communities concerned about the environmental impact of aviation fuel use.

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.
