    RCW 47.06.140: Transportation facilities and services of statewide significance—Level of service standards

    RCW 47.06.140 defines transportation facilities and services of statewide significance in Washington State, including highways, the interstate system, ferry routes, freight railroads, and high-capacity transit systems, while explicitly excluding airport facilities and services from this designation. The law requires the Washington State Department of Transportation to set level of service standards for state highways and ferry routes, in consultation with local governments, while retaining final decision-making authority. Improvements to these statewide facilities are classified as essential state public facilities under RCW 36.70A.200.

    RCW 36.70A.200: Siting of essential public facilities—Limitation on liability

    RCW 36.70A.200 requires counties and cities planning under Washington's Growth Management Act to include a process for identifying and siting essential public facilities — defined as those typically difficult to site, such as airports, state education facilities, regional transportation facilities, correctional facilities, solid waste handling facilities, and inpatient mental health or substance abuse facilities. The law explicitly prohibits any local comprehensive plan or development regulation from completely blocking the siting of such facilities. It also establishes liability protections for jurisdictions acting in good faith to site secure community transition facilities.

    RCW 70.94.037: Transportation activities—”Conformity” determination requirements

    Washington State law RCW 70.94.037 requires that any transportation plan, program, or project in areas that don't meet federal air quality standards must be shown to conform with the state's air quality implementation plan before it can be approved or funded. The conformity determination must be made by the responsible state agency, local government, or metropolitan planning organization overseeing the project. Projects limited strictly to preservation or maintenance work are exempt from this requirement.

    State governance of special purpose districts (ports) and FAA preeminence

    This presentation, prepared for the City of Burien Airport Committee, examines the governance structure of Washington State's special purpose port districts and the FAA's preeminent authority over airport operations. It explains that port districts, enabled by state law since 1911 and governed by directly elected commissioners, hold broad powers including management of airports, while federal FAA regulations take precedence over local planning decisions. The document also touches on noise control considerations relevant to communities near Sea-Tac Airport, referencing state and federal regulatory frameworks.

    P2SSB 5955 (S-4677.1/24) – Senate committee amendment by Ways & Means

    This Washington State Senate amendment to P2SSB 5955, introduced by Senator Robinson through the Committee on Ways & Means, removes an appropriation provision from the bill by striking Section 7 and updating the bill's title language accordingly. The amendment eliminates any dedicated funding allocation that was previously included in the legislation, leaving the bill to create a new section without an attached appropriation.

    P2SSB 5955 (S-4677.1/24) – Senate Committee on Ways & Means amendment S-4747.1

    This Washington State Senate amendment (S-4747.1/24), sponsored by Senator Keiser, modifies legislation related to airport noise mitigation programs administered by port districts. It expands the types of professionals that port districts—such as the Port of Seattle—can hire to inspect sound mitigation equipment, replacing the requirement for a 'state certified building inspector' with the broader option of building inspectors or other professionals experienced in sound testing or window and door installations. The amendment also allows port districts to enter into interlocal agreements with their host counties to contract for such inspection services, and makes technical language changes to the bill's intent section.

    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.

    PSSB 5955 – Mitigating harm and improving equity in large port districts

    Washington State Senate Bill 5955 creates a 'port district equity fund' to help large port districts, such as the Port of Seattle operating Sea-Tac International Airport, pay for aircraft noise mitigation programs in nearby communities. The bill provides an initial one-time appropriation for FY 2025, followed by ongoing funding of up to $10 million per year drawn from sales and use taxes on capital construction projects within the district. It also requires port districts to apply for fund resources to repair or replace noise mitigation equipment that is no longer working or has caused structural damage to properties, with port districts required to match at least half of the Legislature's contribution.

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.
