This draft project schedule outlines the planned timeline for Phase I of Washington State's airport facility, air cargo, passenger, and airspace capacity assessment under ESSB 5121, running from May 2005 through August 2006. Key milestones include advertising for a consultant, developing a detailed scope of work, securing an FAA grant, and completing a final Phase I report by July 1, 2006. WSDOT Aviation was responsible for submitting the findings to legislative committees, the governor, transportation commission, and regional planning organizations.

This 1992 study compares three planning reports on Sea-Tac Airport's future capacity and delays: the 1988 Airspace Update Study, the 1992 Terminal Development Plan, and the 1991 Enhancement Plan. The reports differ significantly in their passenger and flight operation projections for the year 2000, and show striking discrepancies in delay estimates — with the Enhancement Plan projecting delay hours more than five times higher than the Airspace Update Study. The document also outlines proposed solutions to reduce delays, including new runway construction, airspace conflict resolution with nearby Boeing Field, and improved approach procedures.

Letter from Rosemary Zeutschel criticizing the Port of Seattle’s inadequate public involvement process for the Sea-Tac/Boeing Field Airspace Study, arguing that insufficient time was provided for community organizations to review technical documents and provide meaningful input.

Port of Seattle memorandum announcing the second Airspace Study Advisory Committee meeting scheduled for February 24, 1982. The agenda includes aviation demand forecasts for Sea-Tac and Boeing Field, discussion of airfield and airspace capacities, and aircraft delays.

FAA Northwest Region letter to Port of Seattle providing review comments on the second draft forecast of aviation demand for Boeing Field (BFI) proposed for use in the SEA/BFI Airspace Study. Comments focus on aircraft mix data requirements, forecast assumptions, and the need for high and low forecast ranges.

Meeting minutes from the Airspace Study Advisory Committee discussing the study of airspace interaction between Sea-Tac Airport and Boeing Field. The committee reviewed the study’s purpose, organization, scope, and schedule, with presentations on air traffic control and local airspace structure.
