    City of Los Angeles RFI Response: Advanced Air Mobility, Docket No. DOT-OST-2023-0079

    The City of Los Angeles submitted formal comments to the U.S. Department of Transportation in August 2023 regarding Advanced Air Mobility (AAM), calling for stronger local government involvement in shaping national AAM policy. The letter emphasizes safety, equity, and environmental concerns, including the need for rigorous aircraft noise, vibration, and frequency analysis to protect communities already burdened by past transportation decisions. Los Angeles urges federal agencies to require independent environmental studies and ensure that low-income communities and communities of color are not further harmed by the rollout of new aerial vehicle technologies.

    Action memorandum to the Secretary: National Plan of Integrated Airport Systems (NPIAS) 2019-2023

    In September 2018, the FAA submitted the National Plan of Integrated Airport Systems (NPIAS) 2019–2023 report to Congress, identifying 3,340 airports important to national air transportation and estimating $32.5 billion in eligible infrastructure development needs over that five-year period. The report, required by federal law every two years, covers topics including safety, capacity, environmental conditions, runway pavement condition, and financial performance of the national airport system. While this document focuses on broad national airport planning and funding, it does not specifically address noise policy at Seattle-Tacoma International Airport.

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.

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.
