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 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 Aviation Noise and Emissions Mitigation Act, introduced by Rep. Adam Smith (WA-09), aims to help communities near airports — including those around Sea-Tac — deal with the health risks posed by aviation noise and air pollution. The bill would create two EPA grant programs: one funding research and neighborhood-level monitoring of noise and emissions, and another supporting mitigation efforts such as home soundproofing, public health programs, and healthcare services for affected residents. The legislation responds to studies linking airport emissions to increased risks of cancer, heart disease, and asthma, as well as findings that aircraft noise negatively affects children's learning.

The Aviation Impacted Communities Act, introduced by Rep. Adam Smith (WA-09), aims to give residents and local leaders a stronger voice in addressing excessive airplane noise and environmental impacts by requiring the FAA to engage directly with affected communities through newly established community boards. The bill would create an 'aviation impacted communities' designation, allow communities to petition for comprehensive impact studies, and expand funding for noise mitigation beyond current sound-level boundaries. It also establishes a sustainable revenue stream for ongoing relief efforts through the Airport and Airways Trust Fund.

The Aviation-Impacted Communities Act, introduced in the 119th Congress by Rep. Smith of Washington, would require the FAA to provide noise mitigation funding to communities affected by airport noise even if they fall outside the current 65 DNL sound threshold. The bill would make these communities eligible for Airport Improvement Program funds, allow them to establish local boards to address airport noise, and direct the National Academy of Sciences to study aviation impacts at major hub airports — including King County, WA (Sea-Tac) — across the country.
