The Port of Seattle's Part 150 Noise and Land Use Compatibility Study Update, presented to commissioners in September 2013, identifies existing and future aircraft noise impacts around Sea-Tac Airport and recommends mitigation measures such as sound insulation and air conditioning for eligible nearby homes. The study followed an extensive public outreach process begun in 2009, including five public events, briefings to nine local government bodies, and a comment period that drew approximately 70 responses. Once approved by the Commission, the study would be submitted to the FAA for final review, potentially qualifying the recommended noise mitigation measures for federal Airport Improvement Program grant funding.Open full document
