The forecast, sourced from LeighFisher (June 2022, updated August 2023), projects growth from 429,000 operations in 2023 to 567,000 by 2038. -
2023-09-01Appendix A: Aviation Activity Forecast Update: Seattle-Tacoma International Airport (2023)
This technical memorandum, prepared by Leigh Fisher for the Port of Seattle in September 2023, presents an updated aviation activity forecast for Seattle-Tacoma International Airport. It includes Constrained Operating Growth Scenarios (COGS), FAA approval of the forecast update, and airside modeling documentation used to support environmental review. The forecast and operational assumptions outlined in this document serve as the foundation for planning future airport capacity and assessing potential noise and environmental impacts. -
2023-09-01Appendix B Aircraft and Activity Forecast
This technical memorandum, prepared by Leigh Fisher for the Port of Seattle in September 2023, provides an updated aviation activity forecast for Seattle-Tacoma International Airport as part of a FAA Part 150 noise study. It outlines forecast and operational assumptions—including projected aircraft types and flight activity levels—that were used to model future noise conditions around Sea-Tac. The report is accompanied by operational data appendices supporting the airport's long-term noise compatibility planning efforts. -

2016-07-15Air Quality Criteria Pollutant Emissions Inventory Task 2.8: Working Paper – Documentation of Assumptions
This 2016 working paper documents the methods and assumptions used to build an air quality emissions inventory for Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan. Using the FAA's EDMS modeling software, analysts estimated pollution from sources including aircraft engines, ground support equipment, parking, and stationary facilities such as generators and boilers. Aircraft operation data for 2014 was gathered from multiple sources, including FAA tower records, airline guides, and the Port of Seattle's own noise monitoring system. -
2015-03-01Technical Memorandum No. 2: Inventory of Existing Conditions — Seattle-Tacoma International Airport
This 2015 technical memorandum prepared by Leigh Fisher for the Port of Seattle provides a comprehensive inventory of existing conditions at Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan. It covers a wide range of airport infrastructure and operations, including airfield runways and taxiways, passenger terminal facilities, ground transportation, air cargo, general aviation, and airline and airport support systems. The document serves as a baseline assessment of the airport's physical and operational state to inform future planning decisions.
