    Draft report of the Land Use Committee: Sea-Tac Communities Plan

    This draft report from the King County Policy Development Commission's Land Use Committee outlines the planning process for the Sea-Tac Communities Plan, a joint effort between King County and the Port of Seattle funded by a $640,000 FAA grant awarded in 1972. The plan aimed to concurrently develop a master plan for Sea-Tac International Airport and a companion land-use plan for surrounding communities most affected by airport noise and operations. A Policy Advisory Committee representing government agencies, consultants, and community groups oversaw the process, which moved through four phases covering data collection, site analysis, alternative plan development, and final recommendations for adoption by both the King County Council and the Seattle Port Commission.

    Heavy metals in the garden

    This Washington State University Cooperative Extension factsheet explains the risks of heavy metals such as lead, cadmium, and arsenic in garden soils, with a focus on the greater Seattle-Tacoma region. It identifies locations most likely to have contamination, including sites near old painted buildings, heavily traveled roads, and areas affected by the former Tacoma smelter. The factsheet offers practical gardening tips to reduce exposure, such as growing fruiting crops, adding organic matter, liming soil, and washing produce thoroughly.

    Background: Racial and economic inequities in birth outcomes

    A University of Washington Epidemiology researcher, Anna Harrington, presents findings showing that communities near Seattle-Tacoma International Airport have higher rates of preterm births and are home to a disproportionate share of King County's people of color and low-income residents. The presentation proposes a qualitative research study to explore how airport community stakeholders perceive the public health risks of SeaTac air pollution on pregnant people, and what barriers they face in reducing that exposure. The study aims to understand whether risk perceptions and mitigation strategies differ based on the racial identity and income level of pregnant individuals.

    A planning map from the Sea-Tac Communities Plan, sponsored by the Port of Seattle and King County, showing the South Reinforcement Area program application. The map uses color coding to designate zones for acquisition, purchase guarantee, cost-sharing insulation, and limited cost-sharing insulation in the area bounded roughly by S. 200th St. to the north and S. 223rd St. to the south, including grid cells along 16th Ave. S., 24th Ave. S., and Pacific Highway South (SR-99), with a Southeast Conversion Area noted in the upper right.
  • STCP-6.6.5-28-south

    A planning map from the Sea-Tac Communities Plan, sponsored by the Port of Seattle and King County, showing the South Reinforcement Area program application. The map uses color-coded grid cells (labeled N-41 through P-47) to designate zones for acquisition, purchase guarantee, cost-sharing insulation, and limited cost-sharing insulation relative to airport noise impacts, covering the area between approximately S. 252nd St. and S. 272nd St. along Puget Sound, including landmarks such as Woodmont Elementary and Mark Twain Elementary schools.
