    Port Package Update Program News! Issue #1

    The Port of Seattle launched a Sound Insulation Repair and Replacement Pilot Program in February 2024, aimed at addressing mold, water damage, and other problems affecting the roughly 9,400 homes in Burien, Des Moines, Kent, and SeaTac that received Port-funded sound insulation systems. With $6 million in combined Port and State funding, the program will assess and prioritize homes for repair, with work expected to begin on some homes in 2025, though the ultimate goal is securing federal funding to fix all eligible homes. Community organization Sea-Tac Noise.Info is encouraging homeowners to proactively document their issues and connect with the program rather than waiting to be contacted by the Port.

    Seatacnoise.info Receives 4culture Grant For Documentary

    SeaTacNoise.Info has received a grant from 4Culture, King County's cultural funding agency, to help complete a documentary film titled 'Under The Flight Path: A Community History of Sea-Tac Airport.' The film aims to tell the largely untold story of communities living near Sea-Tac Airport from its founding in 1949 to the present, drawing on a library of over 300,000 historical documents. Unlike existing histories focused on the aviation industry's successes, the documentary seeks to provide a balanced perspective for residents and stakeholders as the airport's growth continues to accelerate.

Read This!

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
