    SB5652 introduced in Senate Environment, Energy, and Technology Committee

    Expansive airport bill gets warm first hearing Documents/Schedule Our Take Senator Tina Orwall introduced her bill with an emotional anecdote as to the harms of childhood asthma–and the health benefits of proper air filters.

    Legislation 2026

    A list of programs and changes to City, Port, State and Federal law we can and must implement in the upcoming legislative calendar. The SAMP is the largest and longest expansion in airport history. These policies will reduce noise, pollution, provide mitigation and compensation for decades of inequity. This is a blueprint not only for Sea-Tac, but for every community unfairly impacted by commercial aviation. Solve for Sea-Tac, solve for every airport.

    Match requirements prevent rural and low-capacity communities from accessing climate resilience funding

    More than 60% of federal resilience funding in the Bipartisan Infrastructure Law requires a local match, with an additional 13% requiring a match under certain conditions. Requirements for matching funds have been included in federal funding programs to promote economic efficiency and ensure communities have “skin in the game.” In practice, however, they can impose insurmountable burdens on communities,
