Sustainable Airport Master Plan executive summary Long-range vision
This is Figure 4-1 from the Seattle-Tacoma International Airport Sustainable Airport Master Plan Executive Summary (source: LeighFisher and Port of Seattle, 2016), depicting a color-coded aerial site plan of proposed long-range airport development including new terminals, maintenance facilities, cargo areas, support facilities, hardstands, pavements, and demolition zones across the airfield. -
2025-12-08SAMP Appendix A – Fig 4-1 Operational Forecast Through 2038 (2023)
Bar chart from a LeighFisher forecast (June 2022, updated August 2023) showing historical and projected total aircraft operations at Seattle-Tacoma International Airport, broken down by passenger airlines, all-cargo airlines, and other operations. Operations dipped to 296,000 in 2020 (COVID impact), recovered to 429,000 by 2023, and are forecast to grow to 567,000 by 2038. -
Appendix A Table 4-1 Operational Forecast
Figure 4-1 from a Seattle-Tacoma International Airport planning document shows historical and forecast total aircraft operations (in thousands) from 2011 to 2038, broken down by passenger airlines, all-cargo airlines, and other operations. 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 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. -
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. -

2020-12-21Airfield Simulation Modeling History and Summary: Sustainable Airport Master Plan, Seattle-Tacoma International Airport
LeighFisher memorandum summarizing airfield simulation modeling conducted for the Port Of Seattle Sustainable Airport Master Plan (SAMP) and follow-on NEPA review at Sea-Tac Airport. Covers TAAM (Total Airport and Airspace Modeller) model development from 2015 through mid-2017, including initial calibration to 2014 activity, FAA-requested recalibration to 2016 activity, maximum sustainable throughput experiments, and revised future-year -
2018-05-01Technical Memorandum No. 7: Facilities Implementation and Financial Feasibility — Seattle-Tacoma International Airport
This May 2018 technical memorandum, prepared by Leigh Fisher for the Port of Seattle, outlines near-term capital projects and long-term facility improvements planned for Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan. It evaluates the financial and operational feasibility of major airside, terminal, cargo, and landside projects, and recommends key actions for implementation following completion of the planning process. Note that this document focuses on facilities and financial planning rather than noise policy specifically. -
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.
