TagNorth Sea-Tac Park(165)

The Greater Highline Community Parks Board was organized in early 1981 to represent the local community in developing the North Sea-Tac Park, a project arising from the Port of Seattle's acquisition of land severely impacted by airplane noise from Sea-Tac Airport. The development plan included steps such as securing a master lease with the Port of Seattle, organizing sports and recreation programs, cleaning up and improving the site, and potentially taking over Sunset School for community use. Key milestones between 1980 and 1981 included a $30,000 master plan study, approvals from both the Port of Seattle Commission and King County, and a bid by the Parks Board on all Sunset School buildings contingent on obtaining the master lease.

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. The plan identifies property boundaries, fencing, limits of study, and extended clear zones relevant to nearby Seattle-Tacoma International Airport operations. It reflects land-use planning efforts to balance public park amenities with airport noise and safety constraints in the surrounding community.

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. Some parcels are subject to Port termination rights with 180 days' notice, reflecting the airport's ongoing influence over surrounding land use and open space management.

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.
