The Port of Seattle launched a Sound Insulation Repair and Replacement Pilot Program to assess the effectiveness of previously installed noise insulation packages in homes near Seattle-Tacoma International Airport. Authorized under Commission Order 2024-04 with a $6.5 million tax levy-funded budget—$5 million of which is reserved for design and construction—the program involved community outreach, property owner surveys, and acoustic testing throughout 2024. Properties were prioritized using an equity index to ensure underserved communities were considered, with design and construction work expected to begin in 2025.

The Aviation Noise Working Group met on February 10, 2025, to review operational trends at Seattle-Tacoma International Airport (SEA) and discuss noise reduction efforts. Key topics included the Aviation Near-term Noise Action Agenda, potential airfield noise monitoring, and an assessment of the Sound Insulation Repair and Replacement Pilot Program. The meeting was organized by the SEA Stakeholder Advisory Round Table (StART), which facilitates cooperation between the Port of Seattle and neighboring communities.

The StART Aviation Noise Working Group met in February 2025 to review Seattle-Tacoma International Airport's Late Night Noise Limitation Program, which tracks aircraft noise between midnight and 5 AM and found 8% of operations exceeded thresholds in Q4 2025. The group decided against expanding the program to cover 11 PM–midnight, as most flights in that hour already use quieter aircraft and the change would triple monitored operations with little noise-reduction benefit. Additional updates covered a significant drop in propeller aircraft turns over Burien, progress on the Sound Insulation Program, and action items including a new 5–6 AM operations analysis and a multi-year trends chart.

The City of Des Moines, WA is proposing the formation of a permanent Airport Advisory Committee to advise the City Council on matters related to Seattle-Tacoma International Airport, including review of the Sustainable Airport Master Plan (SAMP), potential interlocal agreements with airport partners, and the city's strategy with the Port of Seattle. The committee would consist of at least three Des Moines residents, including at least one City Council member, and would meet quarterly to evaluate airport-related issues and provide recommendations. Staff submitted the proposal for Council approval at the February 6, 2025 meeting, following a unanimous Council vote in October 2024 to establish such a committee.

This proposed Washington State bill would require large port districts — such as those operating major airports like Sea-Tac — to develop and adopt environmental justice implementation plans aimed at reducing health and environmental disparities in surrounding communities. The plans must include specific goals, measurable metrics, community engagement strategies, and timelines for incorporating environmental justice considerations into port activities. It also establishes oversight for major capital projects valued at $8 million or more, or any actions that increase the number of airport gates.

The Port of Seattle submitted an environmental checklist in January 2025 for a limited update to Seattle-Tacoma International Airport's Water System Plan, covering the period 2025–2028. The update addresses routine maintenance and infrastructure improvements to SEA's drinking water and fire protection system, including pipe replacements, new surge tanks, additional water storage, and a backup water supply connection to Highline Water District. Washington State Department of Health approval and Port of Seattle Commission adoption are required before the plan can be implemented.

The Port of Seattle Commission held a regular meeting on January 28, 2025, at Seattle-Tacoma International Airport's Conference Center, covering routine business such as approval of meeting minutes, claims and obligations totaling over $101 million, and several collective bargaining agreements with airport workers. Key agenda items included a joint marketing agreement with Washington State Tourism worth up to $1.5 million to promote international tourism, as well as authorization for dredging project contracts and airline technical representative services. The meeting was open to the public both in person and virtually via Microsoft Teams.

The South King County Community Impact Fund (SKCCIF) is a $14 million Port of Seattle investment running from 2025 to 2029, aimed at improving quality of life for historically underserved communities in South King County. The fund is divided across three programs: Economic Opportunities for Communities (70%), Environmental Improvements (20%), and Diversity in Contracting (10%). Its mission is to remove systemic barriers by expanding access to living-wage jobs in Port-related industries, enhancing public spaces, and supporting community-led projects.
