A 1973 public opinion survey commissioned by the Port of Seattle and King County found that nearly one in five Highline-area residents considered airplane noise from Sea-Tac Airport their community's single most serious problem, with concern rising sharply among those living in the highest-noise zones. Highline residents were more likely to want to move than those in quieter comparison areas, though the survey also found that the Port of Seattle was viewed favorably by a strong majority across all groups surveyed.

A 1972 University of Washington environmental health report examines the serious health impacts of aircraft noise on residents living near Seattle-Tacoma Airport, including sleep disturbance, psychological effects, and interference with speech in schools. Noise measurements taken at four locations near the airport recorded up to 95 dBA, with dozens of flyovers exceeding 75 dBA even during nighttime sleeping hours, levels researchers considered potentially hazardous to mental and physical health. The report also highlights special risks for vulnerable groups such as young children, the elderly, the sick, and night-shift workers.

A 1972 University of Washington environmental health report examines the serious physical and psychological effects of aircraft noise on residents living near Seattle-Tacoma Airport. On-site measurements recorded up to 95 dBA indoors, with hundreds of daily flyovers exceeding 75 dBA—levels shown by research to disrupt sleep, impair children's school performance, and pose long-term mental and physical health risks. The report also highlights how excessive ambient noise in nearby schools interferes with speech comprehension and the learning process.

This document traces decades of air pollution concerns around Seattle-Tacoma International Airport, drawing on studies from 1970 through 1991 that documented harmful emissions including carbon particles, hydrocarbons, and nitrogen oxides affecting residents living near the airport. It highlights how early research identified health risks and pollution spread up to 12 miles from the runways, yet meaningful follow-up scientific study and regulatory action were largely delayed for 45 years. Community groups, lawsuits, and independent monitoring repeatedly confirmed that nearby residents faced noise, kerosene odors, soot, and air quality violations, while the Port of Seattle externalized the associated public health costs.
