    Potential Aircraft Noise Impact Programs for the Vicinity of Sea-Tac International Airports

    This draft planning document outlines sixteen potential programs to address aircraft noise impacts near Seattle-Tacoma International Airport, ranging from government acquisition and demolition of affected properties to zoning changes and development controls. Each program is described along with a pros-and-cons analysis to help community members and decision-makers evaluate the options. The programs include measures such as converting noisy areas to open space, offering purchase assistance to affected homeowners, granting noise easements, soundproofing buildings, and providing property advisory services.

    Senate Bill No. 3076: Relates to noise abatement control

    Senate Bill No. 3076, introduced by Senators Dore, Mardesich, and Day on January 17, 1974, proposes giving Washington's Department of Social and Health Services the authority to regulate and control noise pollution, including emissions from motor vehicles and aircraft. The bill would allow the department to set noise level limits, investigate complaints, and seek injunctions against violators. Anyone found in violation could face a misdemeanor charge and a fine of up to $100 per offense.

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.
