This map illustrates the F.A.A. density guidelines for the North Sea-Tac Park area, showing recommended population limits per acre across different airport safety zones. The Clear Zone nearest the runway allows the fewest people (approximately 1.5 per acre), while the Extended Clear Zone permits around 2 people per acre, and surrounding residential areas are guided toward densities of 20 to 40 people per acre. A gymnasium is specifically noted at 60 people during games, reflecting how land use intensity is regulated based on proximity to airport flight paths.

This document presents the Master Plan for North Sea-Tac Park, showing a detailed map of proposed and existing recreational facilities including baseball fields, soccer and football fields, tennis courts, a golf course, bicycle/motocross areas, and a Sunset Complex.

This draft map from the City of SeaTac outlines land-use agreements for North SeaTac Park, showing eight numbered zones with different lease arrangements between the Port of Seattle, King County, and the City of SeaTac. Key areas include ball fields, a soccer field, a community garden, and a Highline Botanical Garden, governed primarily by 1991 and 1994 leases expiring in 2070.

This June 2022 report, prepared by Anchor QEA for the Port of Seattle, provides a comprehensive inventory of the 55-acre parcel within North SeaTac Park located near Seattle-Tacoma International Airport. It covers the parcel's development history, cultural context, land use, environmental conditions (including soil, air quality, water, plants, and wildlife), noise levels, recreation, transportation, and utilities. The inventory serves as a baseline reference to inform future planning and policy decisions for this airport-adjacent public land.

This March 2022 report to SeaTac's Parks and Recreation Committee examines the city's existing lease arrangements with the Port of Seattle for North SeaTac Park and explores the feasibility of the city taking ownership of the park. The presentation covers the background of the ownership proposal, an overview of current leases dating back to 1991 and 1994, and outlines next steps including drafting a formal resolution. The park land, currently leased from the Port, encompasses multiple areas governed by agreements that have been amended over the years.

The North SeaTac Park Master Plan (draft) was submitted to the City of SeaTac and King County by Jones & Jones on June 26, 1992. The plan was developed with input from City of SeaTac staff, the Mayor and Council Members, and a citizen North SeaTac Park Advisory Committee, along with King County Parks Division. It outlines the master planning framework for North SeaTac Park, a public green space situated in the community adjacent to Seattle-Tacoma International Airport.

This 1990 agreement between the Port of Seattle, the City of SeaTac, and King County outlines plans to develop North SeaTac Park, including the construction of a new public Activity Center to replace the aging Sunset Activity Center. The Port agreed to contribute up to $2,953,600 toward development costs, while the County took responsibility for design, construction, and eventual demolition of the old facility. The agreement also includes provisions ensuring park uses remain compatible with Sea-Tac Airport operations, prohibiting any structures or activities that would interfere with air navigation or violate FAA regulations.

King County Ordinance No. 8996, adopted April 3, 1989, updates comprehensive land use planning and zoning for the Sea-Tac Airport area, incorporating community input and environmental review to guide orderly development near the airport. The ordinance formally adopts the Sea-Tac Area Update and Area Zoning as official county policy, amending several prior ordinances related to the Highline Communities Plan. It also establishes policies for the development of North Sea-Tac Park, with safety designated as the foremost planning consideration.
