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. The report covers resident surveys, research into the expected useful life of sound insulation building materials, acoustic testing methods, and test results from selected homes. It aims to inform future decisions about repairing or replacing aging noise-reduction treatments in affected neighborhoods.

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.

The session concluded with a question-and-answer period for attendees.

This January 2018 report from the Port of Seattle examines the economic impact of Seattle-Tacoma International Airport, which handled an estimated 46.8 million passengers and roughly 425,860 metric tons of air cargo in 2017. The airport directly supported 19,100 on-site jobs and $5.6 billion in economic activity, while generating nearly $22.5 billion in total economic output and 151,400 jobs across Washington state when multiplier effects are included. The report also highlights the airport's role as a critical trade gateway, including the export of Washington-grown cherries to international markets.

A May 2015 presentation to the Washington State Transportation Commission outlines Sea-Tac Airport's Sustainable Airport Master Plan (SAMP), highlighting the airport's rapid growth—37.5 million passengers in 2014, making it the fastest-growing large hub airport in the U.S. The plan addresses future expansion projects including the NorthStar Alaska Hub and a new International Arrivals Facility. It also details the airport's environmental stewardship efforts, such as reducing air emissions through electric ground equipment, renewable natural gas buses, LED lighting upgrades, and earning North America's first airport Carbon Accreditation Certification.
