Current Port of Seattle recommendations would result in an estimated 107+ acres of commercial aviation development on forested land near SeaTac Airport, including “conceptual site considerations” for 31.5 acres of development inside North SeaTac Park.

This development would occur on land where the FAA and Port of Seattle used eminent domain to remove the homes, schools, and businesses of thousands of residents to make way for airport expansion that was making the area uninhabitable.

During the years when these neighborhoods were being dismantled, and for decades following, multiple community plans indicated that hundreds of mostly-forested acres of this land (shown on this map with dark green shading and labeled North and South Acquisition Areas) would remain as open space use for parks, nature trails, and similar uses.

North SeaTac Park has especially been perceived as a protected public space having been created, as the FAA noted in a 2016 audit, “to compensate area residents for cumulative airport impacts.”

Trees reduce human exposure to aviation pollution causing harmful health impacts near SeaTac Airport, including widespread disease, shorter lives, premature births, and learning problems in children. Public Health Seattle & King County has recognized these connections and recommends increasing green space and trees here.

The Port of Seattle, despite the harmful public health impacts of urban deforestation and its own commitment to restore forests and reduce sprawl, has replaced large areas of forested land with sprawling aviation development in this community - and proposes much more forest removal.

These actions respond to forecasts that regional aviation demand - both passenger and cargo - will double by 2050. They are consistent with the Port’s mission to advance trade and travel.

But that mission - and and Port and FAA policies and culture - which produce aviation sprawl on forested land in a community with low tree canopy and high levels of environmental health disparities - need updating.

Planning is now underway for major expansion of SeaTac Airport that would replace large portions of  remaining forest near the airport with even more polluting structures - actions that would significantly increase area heat, noise, pollution and harm to human health. The FAA, State of Washington, and Port of Seattle cannot meet their commitments to safety, environmental justice and climate action and also go through with these plans.  There is no safe or just way for this community to accommodate continued airport expansion.

A Park for the People

The Port of Seattle “states the Park is the culmination of a long term and very open planning process to compensate the area’s residents for cumulative airport impacts. According to the Aviation Division, the Park is the best compatible use of a severely airport-impacted area".
