    The Gift of Public Funds Bogeyman

    ★ 32
    The authors, including Washington’s Solicitor General, Noah Purcell, reveal how the “gift of public funds” doctrine has become a false barrier for government assistance to communities. For decades, agencies like the Port of Seattle have wrongly claimed that matching requirements, narrow purposes, and small amounts are requirements of the State Constitution although there is absolutely

    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. This was a good idea considering the bill’s complexity. We applaud the legislative aide responsible for summarizing its contents. The bill

    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,

    SHB1847 – Aircraft Noise Abatement Various Provisions

    Washington State's Substitute House Bill 1847, signed into law on March 25, 2020, expands the aircraft noise abatement programs available to port districts by lowering the threshold for eligibility from airports serving more than 900 scheduled jet flights per day (previously 20). The law also enlarges the geographic 'impacted areas' around runways where noise relief programs—such as soundproofing, property acquisition, and transaction assistance—can be offered, extending coverage from six to ten miles north and up to thirteen miles south of runway ends, and from one to two miles from runway centerlines.

    Substitute House Bill 1847 – Aircraft Noise Abatement – Defining aviation impacted area

    Washington State's Substitute House Bill 1847, signed into law in March 2020, expands the aircraft noise abatement programs available to port districts by lowering the qualifying threshold from 900 to 20 scheduled jet flights per day and extending the geographic boundaries of 'impacted areas' around airport runways. The law allows port districts to pursue noise relief measures—including property acquisition, soundproofing, transaction assistance, and mortgage insurance—for communities affected by aircraft noise. It amends three existing state statutes (RCW 53.54.010, 53.54.020, and 53.54.030) and took effect on June 11, 2020.

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.

Read This!

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.
