Seattle-Tacoma International Airport launched a Sound Insulation Repair and Replacement Pilot Program following Commission Order 2024-04, approved on February 27, 2024, with a total budget of $6.5 million — including $5 million reserved for design and construction. The program, funded by tax levy, aims to assess and repair aging sound insulation in nearby homes, incorporating equity guidelines for participation. The 2024 assessment timeline includes resident surveys, acoustic testing, and a final report, with design and construction work planned for 2025.

The Port of Seattle mailed this notice to residents near Sea-Tac Airport informing them about the Sound Insulation Repair and Replace Pilot Program, which aims to address aircraft noise in affected homes. Recipients were advised that a formal survey about the program would be mailed to them in early June. Program information and resources are available in multiple languages at www.portseattle.org/sound-insulation.

The Port of Seattle developed this Qualtrics survey to assess the condition of sound insulation treatments — such as windows and doors — previously installed in homes near Seattle-Tacoma International Airport. Residents are asked to verify their address, confirm property ownership and length of residency, and answer detailed questions about their windows, including how many exist and whether they were installed by the Port. The survey aims to identify items that may need repair, replacement, or maintenance.

The materials cover expected useful lifespans ranging from 5 to 100 years for items such as roofing, flooring, and mechanical systems. These references are intended to support housing assessments and affordable housing planning decisions.
