  Projecting the health and economic burden of aircraft noise

  This study projects the long-term health and economic costs of aircraft noise generated by the NextGen automated flight system, focusing on communities near Baltimore Washington International Airport. Using a mathematical simulation model, researchers estimated the impact of noise exposure on cardiovascular disease, anxiety, annoyance, and low birth weight over periods of 10, 20, and 30 years. The findings are intended to inform noise mitigation policies and provide a clearer picture of the public health consequences of modern air traffic management systems.

  Regional Airport System Plan, 1980-2000, Central Puget Sound region

  ★ 32

  This 1980 draft report, produced by the Puget Sound Council of Governments, outlines a Regional Airport System Plan for the Central Puget Sound area covering the years 1980 to 2000. Funded by the Port of Seattle, the Washington State Department of Transportation, and the Federal Aviation Administration, the plan was developed to guide regional aviation policy and infrastructure decisions across King, Pierce, Snohomish, and Kitsap counties. It was prepared for review by the Standing Committee on Transportation and represents an early framework for managing air travel demand and airport development in the greater Seattle region.

  Results from Soil Contamination Study of King County

  A soil contamination study by Washington State's Department of Ecology and Public Health – Seattle & King County found elevated levels of arsenic and lead in southern King County soils, linked primarily to the former Asarco smelter in Ruston. Contamination levels were highest near the smelter and on Vashon and Maury Islands, with concentrations decreasing further from the source and following prevailing wind patterns. While the findings are a concern rather than an emergency, officials stress that the study reflects regional trends only and cannot predict contamination levels at individual properties.

  Sea-Tac Communities Plan final report Noise Study Volume II

  This 1974 noise study, prepared by MAN-Acoustics and Noise, Inc. for the Port of Seattle and King County, examines aircraft noise impacts on communities surrounding Seattle-Tacoma International Airport. It covers noise measurement methodologies, noise exposure calculations, effects of weather and aircraft location, maintenance runups, thrust reverser noise, and background noise levels. The report also evaluates potential noise control alternatives and flight operational changes aimed at reducing noise burdens on nearby residents.

  Sea-Tac International Airport noise exposure update

  ★ 32

  This June 1982 report, produced by the Port of Seattle, provides an update on noise exposure levels at Seattle-Tacoma (Sea-Tac) International Airport. It documents the extent of aircraft noise affecting surrounding communities, serving as an official record to inform airport noise management and land-use planning policies. The report was part of ongoing efforts by the Port of Seattle to monitor and address the impact of airport operations on nearby residents.

  Sea-Tac-Airport-Final-EIS-Feb.-1996-Vol

  This page is from the Executive Summary of the Sea-Tac Airport Master Plan Update Final Environmental Impact Statement (EIS), discussing noise mitigation strategies including sound insulation, noise budget limits, nighttime limitations, flight corridorization, and land acquisition in the Approach Transitional Area. It estimates acquisition and relocation costs for approximately 309 residential homes and multi-family buildings at roughly $35 million, referencing an FAA Memorandum dated April 30, 1991.

  Section 13: Socio-Economics — Study of the Current and Ongoing Effects of the Operation of the Seattle-Tacoma International Airport

  This 2020 report examines the socio-economic conditions in six south King County cities near Seattle-Tacoma International Airport, including Burien, Des Moines, Federal Way, Normandy Park, SeaTac, and Tukwila. It analyzes demographic trends such as population growth, age distribution, and ethnic profiles from 1997 to 2018, finding that most study area cities grew more slowly than King County overall, with Burien being a notable exception largely due to a 2010 annexation. The report is part of a broader study assessing how airport operations affect surrounding communities across indicators including income, housing, education, employment, and municipal tax revenues.

  SR 509: Corridor Completion/I-5/South Access Road final environmental impact statement and Section 4(f) evaluation

  This January 2003 Final Environmental Impact Statement evaluates proposed highway improvements in southwest King County, Washington, including an extension of SR 509 and upgrades to I-5 between South 210th Street and South 310th Street to improve regional access to Seattle-Tacoma International Airport. Three build alternatives and a No Action Alternative are assessed, with the SR 509 extension designed to accommodate two general purpose lanes and a center high-occupancy vehicle lane in each direction. The project was jointly prepared by the Federal Highway Administration, Washington State Department of Transportation, Port of Seattle, King County, and the Cities of SeaTac and Des Moines.

  The Flight Plan Project Final Environmental Impact Statement

  The Flight Plan Project, a joint effort by the Puget Sound Regional Council and the Port of Seattle, produced this 1992 Final Environmental Impact Statement to evaluate long-term commercial air transportation options for the central Puget Sound region. It examines system-level alternatives ranging from expanding Sea-Tac Airport to building new airport facilities, assessing trade-offs related to noise, air quality, land use, and regional quality of life. The document serves as a programmatic planning tool, with no single preferred alternative identified, intended to guide future site-specific environmental reviews and regional airport policy decisions.
