    Senate Bill 5955: Mitigating Harm and Improving Equity in Large Port Districts

    Washington Senate Bill 5955 (2024) requires large port districts operating airports, such as the Port of Seattle which runs Sea-Tac International Airport, to dedicate a growing share of their annual property tax levy revenue toward programs that reduce noise and air pollution impacts on nearby communities. Starting in 2024, at least half of any levy revenue increase must fund mitigation efforts, rising to a minimum of 1% of total levy revenue by 2025 and increasing by 1% each year up to a cap of 10%. The bill was introduced in response to documented health disparities—including higher rates of asthma, heart disease, and premature births—affecting Black, Hispanic, Native Hawaiian, and Pacific Islander residents who disproportionately live within 10 miles of Sea-Tac Airport.
