    Aviation Mitigation Zones – HB 2276 Striking Amendment (H-3175.2/03)

    ★ 32
    A 2003 Washington State legislative memorandum outlines a proposed striking amendment to HB 2276, which would establish Aviation Mitigation Zones (AMZs) around large regional airports like Seattle-Tacoma International Airport to address noise impacts on nearby communities. The amendment would require the Port of Seattle to levy $10 million annually from 2004 to 2007 into a dedicated mitigation fund, with spending restricted to affected areas within the AMZ. An advisory board and competitive grant process would be created to help distribute funds to eligible local governments, schools, and nonprofits in impacted neighborhoods such as Burien, Des Moines, Tukwila, and Normandy Park.

    Senate Bill Report SB 6240 – Aircraft Noise and Air Quality Mitigation

    Washington Senate Bill 6240 proposes creating a new state account funded by a portion of hazardous substance tax revenue collected on aviation fuel, with money directed toward communities affected by airport noise and air pollution. Starting October 1, 2026, the Department of Commerce would use these funds to run a grant program supporting noise and air quality mitigation projects in aviation-impacted neighborhoods. The bill does not include a direct appropriation and would take effect 90 days after the legislative session in which it is passed.

    Rep. Adam Smith Aviation Impacted Communities Act Fact Sheet — January 2025

    Official one-page legislative summary from Rep. Adam Smith's office (Washington's 9th District) describing the Aviation Impacted Communities Act, which would establish an FAA-community engagement process, create an 'aviation impacted communities' designation, expand mitigation funding beyond current 65 DNL contours, and provide noise-mitigation grants for residences and community facilities.

  • Advanced Air Mobility Request for Public Comment

    The Department of Transportation is seeking public comment on ‘Advanced Air Mobility’ which is a set of rules involving new forms of air transport, including drones and vertical take-off aircraft. You can read the complete description here: Federal Register-2023-10448 Since these changes will profoundly affect all aviation-impacted communities, we can use this as another chance

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.
