Welcome

The Port of Seattle is removing and replanting trees around Sea-Tac Airport to improve safety during takeoffs and landings. The trees identified for removal have grown or will soon grow into the airport’s airspace and pose a hazard to flight operations.

Half of the work, centered around removing and replanting trees on Port property, establishing a low-growing native forest and replacing invasive vegetation, is nearly complete. The second half of the work, centered on non-Port property, began in 2020.

The 174 trees identified for removal in 2020/2021 represent a significant decrease from the number previously identified for removal. The work to lessen the impact of this program is based on public feedback and a comprehensive re-analysis of the airport’s airspace in consultation with the Federal Aviation Administration.

The Port will continue to meet or exceed all federal, state and local regulations protecting the environment. As the State Environmental Policy Act lead agency, the Port has completed an environmental review. The Port expects to conduct similar obstruction removal and replanting work in future years.
