The Federal Aviation Administration (FAA) released a Final Environmental Assessment (EA) in September 2025 for near-term construction and development projects at Seattle-Tacoma International Airport, prepared on behalf of the Port of Seattle. The Final EA was updated from an earlier Draft EA to reflect public and agency comments, correct errors, and remove sections on climate change, environmental justice, and cumulative impacts following changes to federal executive orders, regulations, and a 2025 Supreme Court ruling. These regulatory shifts meant the FAA was no longer required to analyze how the proposed projects might affect vulnerable communities or contribute to broader environmental trends.

This January 2025 technical report, prepared by Environmental Science Associates for the Port of Seattle, documents a pilot program assessing the condition and effectiveness of sound insulation previously installed in homes near Seattle-Tacoma International Airport.

This Port policy (AC-13) establishes standards for disposing of Port-owned property, covering items ranging from capital assets to small equipment, with the goals of saving costs, maximizing returns, and maintaining a proper audit trail. It defines when property should be disposed of — such as when it is excess, obsolete, damaged, or destroyed — and outlines the authorization requirements, including Commission approval for surplus property exceeding a set dollar threshold. Note that this policy does not address land, abandoned third-party property, or consumable supplies.

The Port of Seattle Commission is being asked to approve an $800,000 contribution to the City of Burien for the Miller Creek Culvert Replacement and Stream Restoration project, which aims to fix failing culverts near Sea-Tac International Airport that threaten protected wetland mitigation sites. The project will divert Miller Creek, replace a deteriorating culvert under Des Moines Memorial Boulevard, and construct fish-friendly culverts along 450 feet of restored stream habitat on Port property. Beyond protecting the Port's Clean Water Act permit compliance, the project delivers broader environmental benefits by removing the largest fish barrier on Miller Creek and creating a continuous, passable stream corridor through the watershed.
