TagNorth Sea-Tac Park(165)

In April 1981, the Port of Seattle testified at a public hearing opposing proposed residential (S-R) zoning for areas north of Sea-Tac International Airport, arguing the land falls within the highest aircraft noise impact zone and cannot legally or practically be developed for housing. The Port contended that rezoning these parcels to light manufacturing (M-L) was consistent with the Sea-Tac/Communities Plan and supported by a court ruling finding that residential zoning in such noise-impacted areas is arbitrary and unrealistic. The testimony also challenged the County's authority to impose certain zoning conditions on Port-owned property on the airport's west side.

Zoning amendment document for Highline area properties regarding Airport Open Use designation. Details proposed changes from existing single-family and multi-family zoning classifications to AOU and RS7200 potential AOU, with specific amendments to Area Zoning pages 55, 57, 81, and 83.

Letter from Sea-Tac Airport Manager Oris W. Dunham Jr. to William C. Holstine addressing community concerns about airport operations, including land acquisition programs, noise mitigation, flight operations, and the North Sea-Tac Park development. The letter responds to a November 14 meeting and community questionnaire about Port of Seattle relationships with surrounding neighborhoods.

This 1980 recreation master plan for North Sea-Tac Park was prepared by Jongejan/Gerrard/McNeal, Inc. as a joint planning effort between the Port of Seattle and King County. The plan identifies community recreational needs, assesses natural and manmade site constraints including airport noise impacts, and proposes development guidelines for the park adjacent to Seattle-Tacoma International Airport. It was described at the time as a pioneering example of airport-adjacent land use planning at the national level.

In late 1979, community discussions around Sea-Tac International Airport's north clear zone focused on repurposing approximately 240 acres of noise-impacted land into a multi-use recreational park, featuring soccer fields, tennis courts, nature trails, a golf course, and a motorcycle training area. The Highline Recreation Council unanimously endorsed the North Sea-Tac Park Plan (Sunset Plan), while a separate initiative proposed converting the closed Sunset Junior High School into a regional government records and archives center. Both plans reflect broader efforts to find productive uses for land rendered uninhabitable by airport noise, with funding and community engagement identified as key challenges.

A November 1979 FAA letter to the Port of Seattle expresses support for a 'Modified Passive 2' conceptual plan for the proposed North Sea-Tac Park, while urging that any final park plan carefully weigh adverse impacts on adjacent residential neighborhoods and airport operations. The letter emphasizes that residents in the immediate study area should have meaningful input into the final park plan, and calls for close collaboration among the Port, King County, consultants, and citizens to minimize conflicts between park uses and the unique challenges posed by proximity to a major airport.

In an August 17, 1979 letter to the King County Council, Irene Jones, chairperson of Zone 3 meetings, conveyed strong opposition from local residents to developing a recreational park in the North Sea-Tac area near the airport. Attendees at a public meeting cited safety concerns, high noise levels, and potential tax burdens as reasons against the park plan, arguing that the land should first be fully acquired by the POS before any development is considered. Residents emphasized that their top priority was relief through noise-acquisition, purchase assurance, and sound insulation programs for their existing properties.

In this August 6, 1979 letter from the FAA's Northwest Region to Jongejan Gerrard Associates, the agency provides guidelines on acceptable crowd density levels for recreation planning near Sea-Tac Airport. The FAA outlines four zones around the runway, each with specific limits on peak-time people per acre, ranging from no intensive use in the clear zone closest to the runway to no more than 40 people per acre in outlying areas. The letter also discourages any recreation development that could create bird hazards, incompatible lighting, or electronic interference with airport operations.

Minutes from the August 2, 1979 second meeting of the North Clear Zone Recreation Plan Advisory Committee, held at the Highline Community Center, covering proposed recreational uses for land near Sea-Tac Airport's north clear zone. Topics discussed included an Earthworks Art installation, FAA density guidelines (1.5 people per acre), a possible 9-hole golf course, ATV facilities, use of Sunset Jr. High School, and passive park development around Tub Lake and Lake Reba. Lee Atwood was elected Chairperson, and the committee agreed to reconvene with the consulting firm to develop workable recreation plan recommendations within FAA constraints.
