This document presents the agenda and materials for the second technical workshop of the Regional Aviation Baseline Study, held on October 10, 2019. The workshop covered key aviation metrics across commercial service, air cargo, general aviation, and multimodal access, as well as an analysis of regional aviation needs including capacity versus demand, challenges, and opportunities by sector. A regional airspace analysis and discussion of next steps were also included.

The Puget Sound Regional Council launched a two-year Regional Aviation Baseline Study, funded by a $1.6 million FAA grant, to assess the aviation system across King, Pierce, Snohomish, and Kitsap counties. The study examined existing airport roles, economic contributions, airspace capacity, and community impacts to build a technical foundation for future regional aviation planning decisions. Conducted in phases from 2019 to 2020, the study included stakeholder engagement, public meetings, and a final report outlining strategies for accommodating future aviation demand in the central Puget Sound region.

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.

This draft chapter evaluates alternative measures to reduce growing aircraft delays caused by airspace interactions between Seattle-Tacoma International Airport (Sea-Tac) and Boeing Field, which are projected to worsen significantly between 1990 and 2000. Three main approaches are examined: improving air traffic control (ATC) technology to allow reduced aircraft separations, expanding airport facilities through new runways or reliever airports, and managing demand through flight quotas or peak-period pricing. The chapter concludes that a combination of these measures will likely be necessary, and that action should begin immediately since implementation could take until 1990 when the delays are expected to become critical.

This draft chapter evaluates alternative measures to address growing aircraft delays caused by airspace interactions between Seattle-Tacoma International Airport (Sea-Tac) and Boeing Field, which are projected to worsen significantly from 1990 through 2000. The measures examined include improved air traffic control (ATC) technology, airport facility improvements such as a new runway and reliever airports, and demand management strategies like flight quotas and peak-period surcharges. The chapter emphasizes that, despite delays not being critical until around 1990, immediate planning and commitment from various agencies is necessary given the lengthy implementation timelines involved.

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.

A May 1982 newsletter from the Port of Seattle and King County describing an airspace study examining overlapping flight patterns between Sea-Tac International Airport and Boeing Field. The study found that delays caused by these overlapping traffic patterns were expected to grow gradually through 1990 and accelerate through 2000, particularly at Sea-Tac. The public was invited to a May 18, 1982 meeting to review preliminary findings and provide input on whether to proceed with identifying solutions to reduce aircraft delays.

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.
