  • 2018 Department of Transportation Noise Map near Sea-Tac Airport

    A Bureau of Transportation Statistics (BTS) interactive noise map displaying 24-hour average sound levels (dBA, LAeq) around Seattle-Tacoma International Airport (SEA) for years 2016 and 2018, shown in aviation mode. The map reveals noise contours ranging from 45 dBA (yellow) to over 90 dBA (dark blue/purple), with the highest noise levels concentrated directly along the flight path corridor through communities including Burien, SeaTac, Highline, Sunnydale, and Normandy Park.

    Request for information on Advanced Air Mobility

    The U.S. Department of Transportation is seeking public input to help develop a national strategy for Advanced Air Mobility (AAM), which includes electric and hybrid-electric aircraft capable of vertical or short takeoff and landing. The strategy aims to address safety, infrastructure, community impacts, and regulatory frameworks for these emerging aircraft technologies. While this notice does not specifically address Sea-Tac Airport or local noise policy, noise reduction compared to traditional aviation is cited as one potential benefit of AAM operations.

    Fact sheet: Competitive infrastructure funding opportunities for local governments

    This January 2022 White House fact sheet outlines 25 competitive infrastructure funding opportunities available to local governments under the Bipartisan Infrastructure Law, covering transportation, climate, energy, and environmental programs. It highlights grants for roads, ports, buses, electric vehicle charging, school buses, and community reconnection projects, with funding amounts ranging from $1 billion to $7.5 billion per program. Note: this document focuses on broad federal infrastructure funding and does not specifically address airport noise policy or Sea-Tac Airport.

    Multiple agency fiscal note summary: Transportation policy goals (HB 2688)

    House Bill 2688 proposes changes to Washington State's transportation system policy goals, requiring the Department of Transportation (WSDOT) to evaluate transportation projects submitted to the legislature using updated policy criteria. Multiple state agencies — including the Departments of Commerce, Health, Ecology, and the Interagency Council on Health Disparities — would be required to participate in these project evaluations, along with representatives from vulnerable and highly impacted communities. The fiscal impact on participating agencies is estimated to be non-zero but indeterminate, with the Department of Commerce alone estimating costs of between $21,000 and $35,000 per year.

    *2020 Update* WSDOT Aviation, with the assistance of consulting firm Kimley-Horn, has completed a new statewide Aviation Economic Impact Study for the Washington Aviation System.  The study revealed the state’s 134 public-use airport system contributes 407,042 jobs, $26.8 billion in labor income, and $107 billion in total economic impact (business revenues) to our state’s economy and communities.

    Airport Capacity Benchmark Report 2001

    The FAA's Airport Capacity Benchmark Report 2001 measures the maximum number of flights 31 of the nation's busiest airports can handle per hour under both good and adverse weather conditions. The benchmarks were developed between October 2000 and April 2001 by the FAA and MITRE/CAASD to help understand the relationship between airline demand and runway capacity, and to inform long-term aviation policy decisions. While useful as a reference point, the report notes that these benchmarks are starting points for discussion rather than definitive guides for major investment or scheduling decisions.

    Guidelines for considering noise in land use planning and control

    Published in June 1980 by the Federal Interagency Committee on Urban Noise, this document provides guidelines for incorporating noise considerations into land use planning and control decisions. It was produced jointly by the U.S. Department of Transportation, Department of Defense, Environmental Protection Agency, and Department of Housing and Urban Development. The guidelines are intended to help planners and policymakers manage the impact of noise—such as that generated by airports like Sea-Tac—on surrounding communities through zoning and land use strategies.

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.
