Normandy Park City Manager Mark Hoppen outlines the city's efforts to address Sea-Tac Airport noise and air quality concerns, noting that direct lawsuits against the FAA have had limited success. Key initiatives include a joint jurisdictional response to the Sustainable Airport Master Plan, a Washington State baseline airport conditions study, and a University of Washington ultrafine particulates study aimed at building evidence for federal health-based legislation. Residents are encouraged to review two StART Meeting presentations on aircraft noise and arrival altitudes, particularly slide 37 of the Altitude Analysis, which shows an increase in cargo flights potentially linked to local noise complaints.

This document presents a community challenge to the FAA's environmental review (CATEX) of new flight routes near Seattle-Tacoma International Airport, arguing that the FAA's own noise analyses show significant noise increases in the surrounding General Study Area that exceed the agency's own significance thresholds. The authors contend that the FAA could not rely on the outdated 2013-2018 Port of Seattle Part 150 noise study, and that the FAA's independent analyses revealed noise level jumps ranging from 5.2% to nearly 60% across various decibel contours. The document concludes that the FAA's declaration of 'no noise impacts' is implausible given data showing that portions of previously quiet neighborhoods now experience non-compatible land use noise levels above 65 dB DNL.

This 2018 Harvard University master's thesis by Bryan Johnson examines health-based criteria that could be used to better manage noise from airports and aircraft. The research explores how noise exposure standards and guidelines could be grounded in public health evidence, offering a framework for more effective noise policy. It is relevant to ongoing discussions about managing community noise impacts around busy airports like Sea-Tac.
