Chapter 53.54 RCW authorizes Washington port districts operating large airports (such as Sea-Tac) to carry out programs that reduce the impact of jet aircraft noise on surrounding neighborhoods, including purchasing properties, providing soundproofing, and offering transaction assistance to affected homeowners. The law defines 'impacted areas' with specific distance limits from runways and allows properties within those boundaries to receive noise mitigation benefits. Recent 2024 updates expand the program to allow inspection, repair, or replacement of previously installed noise mitigation equipment that is no longer working as intended or has caused structural damage.

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 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.

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.

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.

Washington State's Engrossed Second Substitute Senate Bill 5955, signed into law on March 19, 2024, addresses aircraft noise mitigation for large port districts like the Port of Seattle, which operates Seattle-Tacoma International Airport. The law allows the port to repair or replace noise mitigation equipment that is no longer functioning properly or has caused structural damage to nearby properties, using non-federal local funding. It also acknowledges that communities of color — including Black, Hispanic, Native Hawaiian, and Pacific Islander residents in King County — are disproportionately impacted by airport noise, and establishes a state partnership to improve equity and responsiveness in noise mitigation efforts.

Washington State E2SSB 5955 creates the Port District Equity Fund to help large port districts, such as the Port of Seattle, repair or replace failing aircraft noise mitigation equipment in nearby homes and properties. The Department of Commerce administers the grant program, which requires port districts to match at least half of state funding, and mandates annual public reporting on inspections and repairs. The program is set to expire July 1, 2029, with a legislative audit review, and will be fully repealed by July 1, 2030.

Engrossed Substitute Senate Bill 5950, passed by the Washington State Legislature on March 7, 2024, is a fiscal appropriations bill that adopts a state budget for the biennium running from July 1, 2023, through June 30, 2025. The bill authorizes spending from various state funds for agency salaries, wages, and other specified purposes, while amending several existing statutes related to financial management. Note: This bill addresses general state fiscal matters and does not contain provisions specifically related to Sea-Tac Airport noise policy.

This is a fiscal note summary for Washington State Senate Bill 5955, which concerns large port districts. The document estimates operating expenditures primarily from the Department of Commerce, ranging from approximately $113,104 in the 2023-25 biennium to $114,136 in subsequent biennia, along with capital budget costs starting at $86,586. The Office of State Treasurer notes non-zero but indeterminate cash receipt impacts, while other agencies such as the Department of Revenue and Department of Ecology report no fiscal impact.
