The most requested documents–and all related-content
This page is an attempt to solve a problem we’ve had since the beginning: how to get visitors to study documents and all the related content which often provides the necessary context. For example, most studies are meant to be read by specialists. If you are a layperson, you may only be interested in the ‘one-pager’. This page shows you both.

1982-04-01Preliminary Assessment of Airspace Interactions: Seattle-Tacoma International Airport and King County International Airport
A 1982 draft working paper prepared by Peat, Marwick, Mitchell & Co. for the Port of Seattle assessed airspace interactions between Seattle-Tacoma International Airport (Sea-Tac) and King County International Airport (Boeing Field). The study analyzed existing and projected airfield capacities, aircraft delays, and the effects of overlapping airspace on both airports, taking into account factors such as air traffic demand, aircraft mix, weather conditions, and runway procedures. Its findings were intended to help the Port of Seattle determine whether more detailed investigation and mitigation measures were needed in a subsequent phase of the study. -
1980-11-19Regional Airport System Plan, 1980-2000, Central Puget Sound region
★ 32This 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. -
1992-10-01The 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.
