Very High areas can support intensive uses like sports fields and horse trails, while Low areas are too environmentally sensitive for most development.

2025-05-13Letter of intent: City of SeaTac offer to acquire North SeaTac Park from Port Of Seattle
In May 2025, the City of SeaTac formally offered to purchase approximately 214 acres of North SeaTac Park and Pat Ryan Field from the Port of Seattle, proposing $20 million in park improvements and the creation of a nonprofit foundation to manage the funds. The letter argues the park is surplus to the Port's aviation needs yet essential to community health, serving roughly 650,000 visitors annually as a buffer against airport noise and air pollution. The offer, submitted by City Manager Jonathan Young, is intended to fulfill Port Order No. 2024-12, which directed the Port to develop options for permanently preserving the land as public parkland. -
