These emails, dated October–November 2019, relate to a study of ground-level noise at Seattle-Tacoma International Airport initiated by the StART Aviation Noise Working Group. Noise consultant Brad Nicholas of HMMH sought input from surrounding cities, including Burien (which had suspended its StART membership), on which noise sources to analyze and where to place monitoring equipment. Community advocate Sharyn Parker responded with detailed recommendations, arguing the consultant should first correlate existing noise complaints and monitor records with engine run-up events before soliciting public input, and identifying engine run-ups and reverse thrust as the two primary sources of airfield ground noise.Open full document
Notes
An email from Phyllis Shulman of Civic Alchemy to Brian Wilson of the City of Burien, requesting input on the scope of an airfield noise analysis at Sea-Tac Airport being conducted by noise consultant HMMH. The email asks for feedback on ground noise sources to include in the analysis and suggested locations and times for noise monitoring. A follow-up email from Sharyn Parker provides detailed commentary on the study scope, critiquing the consultant’s approach and identifying engine run-ups and reverse thrust as primary airfield noise sources.
