    Senate bill report SB 5955: Mitigating harm and improving equity in large port districts

    Washington Senate Bill 5955 proposes creating a 'port district equity fund' to help large port districts—such as the one operating Sea-Tac Airport—pay for aircraft noise mitigation programs. The fund would be seeded with a $10 million appropriation for fiscal year 2025 and subsequently replenished by sales and use tax revenue collected on capital construction projects at the airport, with the port district required to match at least half of state-provided funds. The Department of Commerce would administer grants from the fund to cover costs such as inspecting and repairing soundproofing equipment in nearby homes and addressing any structural damage caused by its installation.

    Assurances: Non-airport sponsors undertaking noise compatibility program projects

    This FAA document outlines the legal assurances that non-airport sponsors (such as local governments near an airport) must agree to when receiving federal grant funds for noise compatibility projects. Sponsors must comply with a wide range of federal laws, executive orders, and regulations — covering areas like civil rights, environmental protection, labor standards, and property acquisition — for the duration of the project, up to 20 years. These assurances become legally binding upon acceptance of the federal grant offer.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

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.
