Flight Corridor Safety Program

The Port of Seattle has an ongoing program to remove trees around SEA Airport to improve safety during takeoffs and landings and replant in their place, native, low-growing trees. 

The first phase of work, completed in 2019, centered around trees on Port property.  The second phase of the work, centered on non-Port property, is nearing completion. The next phase of work, on Port and non-Port property, begins in 2023 with surveying.  Removal and replanting are expected to begin in 2025.

The Port will continue to meet or exceed all federal, state and local regulations protecting the environment.
