This 2018 technical memorandum outlines a Sustainability Planning and Management Strategy for Seattle-Tacoma International Airport, developed by Leigh Fisher and Synergy Consultants for the Port of Seattle. It establishes sustainability goals, objectives, and metrics across financial, environmental, and social focus areas, drawing on FAA guidance and Port of Seattle commitments. The document also addresses climate change risks to airport facilities and provides a framework for integrating sustainability into near-term airport development decisions.

This 2018 technical memorandum prepared by Leigh Fisher for the Port of Seattle provides an environmental overview of Seattle-Tacoma International Airport as part of its Sustainable Airport Master Plan. It examines existing environmental conditions across topics such as air quality, noise, water resources, biological resources, and hazardous materials, then assesses how the airport's near-term construction and improvement projects could affect those resources. The document is intended to guide planners in understanding potential environmental impacts — including noise and compatible land use — before major airport development decisions are finalized.

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.

This 2018 technical memorandum, prepared by Leigh Fisher for the Port of Seattle, outlines near-term construction projects, financial feasibility, and long-term vision for Seattle-Tacoma International Airport as part of its Sustainable Airport Master Plan. It covers major airside, terminal, cargo, and landside projects, along with an assessment of airfield operational feasibility and recommended actions following the plan's completion. While focused primarily on facilities and finance, the document provides context for infrastructure decisions that may affect airport operations and surrounding communities.

Sea-Tac Airport saw record activity between 2014 and 2017, with over 46 million passengers and 425,895 metric tons of cargo passing through in 2017 alone. Passenger growth is slowing — dropping from a 13% year-over-year increase in 2015 to just 2.6% in 2017 — while air cargo, driven largely by domestic freight, surged 16% compared to the prior year. Summer months remain the busiest for passengers, and air mail volumes have shown a steady annual increase throughout the period.

This April 2018 Port of Seattle briefing examines traffic congestion challenges at Seattle-Tacoma International Airport (SEA), whose roadway system was originally designed in 1968 for just 5 million annual passengers. It reviews how a major road realignment in 2008 for Light Rail helped reduce gridlock by removing return-to-terminal loop ramps and cutting recirculating vehicle traffic by 40%. The briefing emphasizes that managing landside access at SEA requires a comprehensive, long-term strategic policy to handle the airport's growing transportation demands.

This 2018 Port of Seattle briefing outlines near-term traffic mitigation strategies for Sea-Tac Airport's increasingly congested roadway system, which was originally designed for 5 million annual passengers but now handles far greater volumes. Key measures include a Traffic Mitigation Plan that restricts access to southbound airport freeways during peak periods, and a new TNC 'Re-Match' program that allows rideshare drivers who have just dropped off passengers to immediately pick up new ones without returning to the remote 160th Street holding lot. The Re-Match pilot reduced passenger wait times by one-third and eliminated an estimated 30,000 deadheading trips in December 2017, while also reducing expressway congestion near the terminal.

FAA categorical exclusion document for updating a Letter of Agreement between Seattle-Tacoma International Airport’s Air Traffic Control Tower and Seattle Terminal Radar Approach Control to automate a 250° westerly turn for southbound turboprops during north-flow operations. The automated turn would be suspended between 10 pm and 6 am in response to comments from the City
