    North SeaTac Park master plan draft

    ★
    This 1992 draft Master Plan for North SeaTac Park was submitted by landscape architecture firm Jones & Jones to the City of SeaTac and King County. The plan outlines proposed development and improvements for North SeaTac Park, a public green space in the community surrounding Seattle-Tacoma International Airport. The document reflects a collaborative effort involving city staff, elected officials, a citizen advisory committee, and King County parks representatives.

    Ordinance No. 2883: An ordinance adopting the Sea-Tac Communities Plan

    ★ 32
    King County Ordinance No. 2883, passed in September 1976, officially adopted the Sea-Tac Communities Plan as an addendum to the King County Comprehensive Plan, establishing it as the guiding policy for land use, development, and redevelopment around Sea-Tac International Airport. The plan, developed with Federal Aviation Administration grant funding and extensive community involvement, addresses noise programs, open space acquisition areas, and compatible land use in the airport's vicinity. It required coordination between King County and the Port of Seattle on any future changes, with the Highline Communities Plan designated as the official zoning guideline for implementing its land use concepts.

    Carrying capacity map, North Sea-Tac Park

    This document presents a Carrying Capacity map for North Sea-Tac Park, classifying land areas into four categories—Very High, High, Moderate, and Low—based on their suitability for various recreational activities. Very High areas can support intensive uses like sports fields and horse trails, while Low areas are too environmentally sensitive for most development. The map appears to be part of a passive recreational planning study examining how different zones of the park can be used without causing significant environmental harm.

    Letter of intent: City of SeaTac offer to acquire North SeaTac Park from Port Of Seattle

    In May 2025, the City of SeaTac formally offered to purchase approximately 214 acres of North SeaTac Park and Pat Ryan Field from the Port of Seattle, proposing $20 million in park improvements and the creation of a nonprofit foundation to manage the funds. The letter argues the park is surplus to the Port's aviation needs yet essential to community health, serving roughly 650,000 visitors annually as a buffer against airport noise and air pollution. The offer, submitted by City Manager Jonathan Young, is intended to fulfill Port Order No. 2024-12, which directed the Port to develop options for permanently preserving the land as public parkland.

    Tub Lake / Sunset Park site hazard assessment report

    The Tub Lake/Sunset Park site in SeaTac, located one mile north of Seattle-Tacoma International Airport, was contaminated by decades of illegal dumping of waste oil and bilge oil from ships between 1941 and 1945, as well as leaking underground storage tanks at a King County road maintenance facility. Environmental sampling conducted in 1990 detected petroleum hydrocarbons, benzene, and other chemicals exceeding cleanup standards in soil, sediment, and water, with contamination estimated to cover 2-3 acres up to 12 feet deep beneath nearby playing fields. The Port of Seattle, which owns the southern wetlands portion of the site including Tub Lake, fenced the area in the 1970s after demolishing residences in the airport's landing pathway, though public access and ongoing contamination remained concerns at the time of the assessment.

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.

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.
