This presentation, sponsored by the Port of Seattle and delivered by ESA Senior Vice President Steve Alverson on May 22, 2018, provides an introductory overview of aircraft noise for community members and stakeholders. It covers the evolution and quantification of aviation noise, how it is regulated, and draws on Alverson's 37 years of experience conducting over 200 aviation noise studies. The session concluded with a question-and-answer period for attendees.

This January 2018 report from the Port of Seattle examines the economic impact of Seattle-Tacoma International Airport, which handled an estimated 46.8 million passengers and roughly 425,860 metric tons of air cargo in 2017. The airport directly supported 19,100 on-site jobs and $5.6 billion in economic activity, while generating nearly $22.5 billion in total economic output and 151,400 jobs across Washington state when multiplier effects are included. The report also highlights the airport's role as a critical trade gateway, including the export of Washington-grown cherries to international markets.

A May 2015 presentation to the Washington State Transportation Commission outlines Sea-Tac Airport's Sustainable Airport Master Plan (SAMP), highlighting the airport's rapid growth—37.5 million passengers in 2014, making it the fastest-growing large hub airport in the U.S. The plan addresses future expansion projects including the NorthStar Alaska Hub and a new International Arrivals Facility. It also details the airport's environmental stewardship efforts, such as reducing air emissions through electric ground equipment, renewable natural gas buses, LED lighting upgrades, and earning North America's first airport Carbon Accreditation Certification.

This Airport Key Map, published by the Port of Seattle on June 15, 2014, provides a general reference overview of property zones surrounding Seattle-Tacoma International Airport. It identifies distinct areas including the Airfield, Terminal, Commercial, South of Airfield, South of 200th, and North of Airfield zones, and distinguishes between Port of Seattle property, lease boundaries, non-Port property, land available for redevelopment, and the proposed SR 509 corridor. The aerial photo, taken in Spring 2012, is intended for general reference only and is not approved for navigation use.

In September 2012, the Port of Seattle Commission considered a $6 million request to create a new Sustainability Master Plan (SMP) for Seattle-Tacoma International Airport, replacing an outdated 15-year-old plan. The update was driven by nearly 50% passenger growth since the last plan, rising capacity pressures on roadways, terminals, and taxiways, and the need to meet FAA requirements for federal grants and environmental permits. The SMP aimed to guide long-term airport development through 2015, balancing future growth with sustainability goals within the airport's existing footprint.

This January 2002 Revised Draft Environmental Impact Statement evaluates proposed improvements to SR 509 and I-5 in southwest King County, Washington, including a freeway extension to enhance southern access to Seattle-Tacoma International Airport. The study, prepared jointly by the Federal Highway Administration, WSDOT, Port of Seattle, King County, and the Cities of SeaTac and Des Moines, examines three build alternatives and a no-action alternative, differing in their proximity to Des Moines Creek Park and the airport runway protection zone. The proposed SR 509 extension corridor would be a minimum of 200 feet wide to accommodate general purpose and high-occupancy vehicle lanes in each direction.

The City of SeaTac conducted an environmental review of the Des Moines Creek Basin Restoration Projects, a multi-agency effort involving the cities of SeaTac and Des Moines, the Port of Seattle, and King County. The project aims to improve water quality, reduce flooding, and restore fish habitat along Des Moines Creek by building a new detention facility, installing a high-flow bypass pipe, and maintaining low-flow water levels during dry summer months. The city's staff determined that the project does not require a full Environmental Impact Statement, as it is not expected to have a significant adverse impact on the environment.

In March 1996, an Expert Arbitration Panel reviewed whether the Port of Seattle had met noise reduction requirements set by the Puget Sound Regional Council as a condition for approving a third runway at Sea-Tac International Airport. A majority of the Panel concluded that, despite the Port's extensive noise abatement programs, it had not demonstrated a sufficient reduction in real, on-the-ground noise impacts to satisfy Resolution A-93-03. This decision left the noise condition as the sole remaining hurdle for authorizing the third runway's construction.

Resolution No. 3212, adopted by the Port of Seattle in 1996, approved the construction of a new third runway at Seattle-Tacoma International Airport (Sea-Tac) to address growing air traffic demand and reduce delays caused by poor weather conditions. The resolution followed years of regional studies, environmental impact reviews, and public involvement, including findings that no feasible alternative airport sites existed in the four-county area. It also committed the Port to fulfilling additional noise reduction measures as required by Puget Sound Regional Council Resolution A-96-02.

In November 1983, the Port of Seattle sent this letter and attached survey summary to attendees of neighborhood workshops held near Jackson International Airport (Sea-Tac), informing them of community attitude surveys conducted by McClure Research Company on aircraft noise concerns. The surveys gathered resident opinions on potential noise remedy programs—including purchase guarantees, noise insulation cost-sharing, and avigation easements—to help planners assess program feasibility and likely participation rates. Results showed that workshop attendees' concerns closely mirrored those of the broader affected community living in areas with noise levels of 70 Ldn and above.
