This 1985 Master Plan Update, prepared by Peat Marwick/TRA for the Port of Seattle, outlines the long-term development strategy for Sea-Tac International Airport to handle projected growth in air traffic through the early 2000s. The plan rules out construction of new runways due to existing capacity, prior investment, and environmental concerns, while recommending expansion of the passenger terminal complex to accommodate up to 55 air carrier gates and 25 commuter airline gates. Planning activity levels projected total annual passengers growing from 12.5 million in the short term to 21 million in the long term.

This November 1983 document outlines the Master Plan Update for Jackson International Airport (Sea-Tac), prepared by Peat Marwick and TRA for the Port of Seattle.

In November 1972, the King County Council passed Motion No. 1019, authorizing the County Executive to apply for approximately $640,000 in federal grant funding from the U.S. Department of Transportation's Federal Aviation Administration. The funds were intended to support a joint Port of Seattle–King County Master Plan Study of Seattle-Tacoma International Airport, prompted by citizen concerns in South King County about airport expansion and its environmental impacts. The motion also authorized the County Executive to enter into agreements with other public bodies and execute any contracts required by the FAA to carry out the study.
