About Highline Forest and North SeaTac Park

Tree Action Seattle is supporting our ally, Defenders of Highline Forest, as they fight for the survival of two large forests protecting frontline communities near SeaTac Airport: the North SeaTac Park Forest and Riverton Heights Forest. Both forests are owned by the Port of Seattle, which plans to develop them as “aviation commercial” and cargo warehouses. Residents of these communities suffer from proximity to airport emissions and are lower income. They have shorter lives and worse health than people in other Washington cities on nearly every metric, from infant birth weight to cancer and asthma. Some of the North Seatac site was originally promised as green space to mitigate the construction of Seatac Airport.
