  • Aerial View of Sea-Tac Airport Showing Terminal, Gates, and Noise-Contour Boundary Line

    Aerial photograph looking north over Seattle-Tacoma International Airport, showing the main terminal, gates with Alaska Airlines and other carrier aircraft, taxiways, and surrounding grounds. A red line is drawn on the image demarcating what appears to be a property or noise-contour boundary on an undeveloped grass area south of the airport perimeter road, adjacent to a light rail line and parking area.

    CASE officers and contacts list

    This document appears to be an organizational roster for CASE (Citizens Against Sea-Tac Expansion), listing officer positions and contact information including a Chair (acting), Vice Chair, Treasurer, Secretary, and members of Technical and Research Committees focused on noise and environmental health concerns. The document references a goal of addressing airport expansion alternatives and includes phone numbers for key members such as Loretta Bower (Treasurer) and Joan Bell (Secretary). It likely dates from the early period of community organizing around Sea-Tac Airport expansion opposition.

    RCAA information on air capacity issues

    A letter from the Regional Commission on Airport Affairs (RCAA) to Senator Skratek urges review of air capacity issues related to Sea-Tac Airport expansion, noting that the expansion could negatively affect many people. The letter encloses a book suggested by Jeff Newell containing executive summaries and charts covering air capacity issues, and requests 30 minutes of the Senator's time before the final Transportation Policy Board vote on March 4. The letter is endorsed by a wide range of community organizations, cities, and advocacy groups opposed to or concerned about Sea-Tac expansion.

  • Seattle Times Infographic: Sea-Tac Airport IAF Gate Layout Limits for Large Widebody Aircraft

    An infographic published by The Seattle Times (credited to Mark Nowlin, sourced from Port of Seattle) illustrating design problems at Sea-Tac Airport's new International Arrivals Facility, showing how gate layout limits large widebody aircraft from docking simultaneously. The diagram details the 780-foot-long walkway connecting Concourse S to the IAF, baggage claim carousels, customs and border protection flow, and passenger routing for both Seattle-bound travelers and connecting flight passengers.

    Sea-Tac Airport Parking Lots Aerial

    Black-and-white aerial photograph showing a large commercial airport with a curved terminal building, a multi-level parking garage featuring distinctive circular ramp towers, taxiways, and numerous commercial jet aircraft at gates. The architectural style and aircraft visible suggest a photograph from the late 1960s or early 1970s, consistent with the era of Sea-Tac Airport's early expansion, though no visible text or markings in the image confirm the specific location or date.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
