TagNorth Sea-Tac Park(165)

This document presents FAA density guidelines for the North Sea-Tac Park area near Seattle-Tacoma International Airport, showing recommended population limits per acre across different zones. Areas closest to the runway are designated as a 'Clear Zone' allowing only 1.5 people per acre, while an 'Extended Clear Zone' permits 2 people per acre, and surrounding residential areas are limited to 20–40 people per acre. A gymnasium on the map is noted as accommodating 60 people during games, illustrating how the guidelines account for concentrated gatherings near airport flight paths.

This document presents four conceptual land-use plans for North Sea-Tac Park, ranging from 'Passive' to 'Active' configurations, each showing different proposed recreational facilities such as tennis courts, golf courses, archery targets, baseball fields, and exercise trails. Handwritten annotations question the fate of certain features, including the Highline Athletic Complex and a 'little league field,' and note that a golf course of approximately 120 acres was considered in connection with Boulevard School and Club Moore. The plans appear to be early planning documents exploring how the park land could be developed or preserved under varying levels of recreational activity.

This document covers planning considerations for North Sea-Tac Park, including an analysis of parking demand across various recreational facilities such as golf courses, sports fields, and trail systems, estimating a total parking need of 516 spaces based on adjusted peak usage. It also addresses air support facility requirements near Sea-Tac Airport, describing clear zone and extended clear zone boundaries where land use is restricted to prevent hazards to aircraft. Within these clear zones, tall buildings, smoke-producing facilities, bird-attracting features, and large gatherings of people are prohibited to minimize risk to approaching and departing aircraft.

Officials from the Port of Seattle, the FAA, and King County dedicated the new North Sea-Tac Park, a 250-acre recreational complex developed in the clear zone off the north end of Seattle-Tacoma International Airport. The park, leased to the Greater Highline Community Parks Board, features an equestrian area, motocross course, cross-country track, and an activities center, but faces financial and operational challenges including density restrictions limiting the number of visitors per acre at any one time. The parks board has sought changes to the lease, including loosening density guidelines and establishing a bingo operation to fund development, though airport officials consider revisions to the gambling ban unlikely.

The North Sea-Tac Park Master Plan Update is a joint planning document produced by King County and the Port of Seattle, prepared by Triangle Associates/Jones & Jones. It outlines recommended updates to the master plan for North Sea-Tac Park, including a phased development program and alternative implementation strategies. The plan reflects a collaborative effort to guide the park's future development in the area surrounding Seattle-Tacoma International Airport.
