    Grid 1: 2013 Baseline Map — Des Moines and Sea-Tac Area Schools

    This map covers the Des Moines and SeaTac area in Washington State, showing residential streets, major roads including SR 99, SR 509, SR 516, and Interstate 5, along with several schools such as Mt. Rainier High School, Pacific Middle School, Midway Elementary, Des Moines Elementary, and St. Philomena School. A purple diagonal corridor crosses the map, likely representing a flight path or noise contour zone associated with Seattle-Tacoma International Airport, while an orange boundary outlines a specific study or impact area in the southern portion of the map. The document appears to be part of an airport noise or land-use planning study examining how SeaTac flight operations affect surrounding communities.

    Letter to Port Of Seattle Commissioners regarding STCP and maximum compatibility

    In this April 26, 1983 letter to the Port of Seattle Commissioners, resident Virginia E. Dare urges the commission to honor its commitment to 'maximum compatibility' between Sea-Tac Airport and surrounding neighborhoods, as originally promised under the Sea-Tac Community Plan (STCP) launched in 1972. The letter emphasizes that community members were guaranteed a direct, ongoing role in planning decisions—including noise mitigation, land acquisition, and density guidelines—through a formal Community Involvement Program. The author calls on commissioners to uphold that process as they enter a new noise remedy program update that will reassess FAA density guidelines affecting nearby residents.

    The Role of the Policy Advisory Committee, March 1983

    This March 1983 document outlines the proposed role and restructured composition of the Policy Advisory Committee (PAC), a body formed to serve as a communication link between Sea-Tac International Airport and its surrounding communities. It defines five key responsibilities for PAC, including monitoring the Sea-Tac/Communities Plan, addressing airport-related issues, and making recommendations to King County and Port of Seattle officials. The document also proposes reforms to membership selection, including three-year terms, formal application procedures, public notification requirements, and geographically based citizen representation.

    Complaints may force change in PAC picks

    A 1983 Times-News article reports that complaints about the Highline Community Council's informal and inconsistent process for appointing citizen representatives to the Policy Advisory Committee (PAC) — the body overseeing Sea-Tac airport development and noise policy — may force a reform of the selection method. Critics argued that appointees often lacked knowledge of the PAC's purpose and that residents most affected by airport noise were being excluded. A six-member sub-committee was formed to investigate the current process and recommend alternatives.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

Read This!

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.
