    Documents catalogued as received in 1991

    This catalog log lists three transportation planning documents received in 1991 and accessioned into an archive between 2001 and 2003. The documents cover Puget Sound regional transportation alternatives (the Flight Plan Project), air pollutant contributions at Seattle-Tacoma International Airport, and a feasibility study for preserving the Stampede Pass Rail Corridor. Together they represent early 1990s regional planning efforts related to air quality, rail, and transportation policy in the greater Seattle-Tacoma area.

    Documents catalogued as received in 1996

    This catalog lists documents received in 1996 related to Seattle-Tacoma International Airport planning and policy, including environmental impact statements, noise arbitration hearing transcripts, air quality studies, and budget documents. Key sources include the Port of Seattle, the FAA, the Airport Communities Coalition (ACC), and various consulting firms, covering topics such as the proposed Sea-Tac Master Plan Update, a third runway, groundwater studies, and community noise mitigation. The collection reflects ongoing disputes between the Port of Seattle and surrounding communities over airport expansion impacts during the mid-1990s.

    RCAA Letter to City of Des Moines: EMT Conveyor Belt Proposal for Sea-Tac Airport Fill Material Hauling, with Sea-Tac Friday Letter on Port Of Seattle 1999 Airfield Improvement Project Haul Permit

    These documents relate to the 1999 Sea-Tac Airport airfield improvement project, including a haul permit issued to Gary Merlino Construction for trucking rock and concrete along designated routes near the airport, with restricted operating hours during the school year. Also included is a 1998 letter from the Regional Commission on Airport Affairs describing a proposal by Environmental Materials Transport LLC to build a temporary barge terminal near Des Moines Creek Beach Park, with a conveyor system to move fill material to Sea-Tac Airport as an alternative to truck hauling. The materials reflect community and municipal concerns about construction traffic, noise, and environmental impact associated with airport expansion activities in the greater Sea-Tac area.

    Truth in Aviation: The newsletter of the Regional Commission on Airport Affairs, Vol. 5, No. 1, Spring 1998

    This 1998 newsletter from the Regional Commission on Airport Affairs covers several controversies surrounding Sea-Tac Airport's expansion, including a 24% cost overrun on the new parking garage, Port staff admitting they lack the capacity to manage over 100 simultaneous expansion projects, and the Highline School District launching an independent study of airport noise impacts on classrooms after failed negotiations with the Port. Additional issues covered include a proposed wetlands destruction permit for the third runway site, plans to extend King County International Airport's runway closer to Georgetown neighborhoods, and legal battles over city comprehensive plans that opposed airport expansion.

    Why the Port Of Seattle’s 3rd runway EIS fails adequately to examine impacts to wetlands and prescribes inadequate mitigation

    This 1997 document argues that the Port of Seattle's Environmental Impact Statement (EIS) for a proposed third runway at Sea-Tac Airport inadequately examines impacts on wetlands and fails to prescribe sufficient mitigation measures. It contends that the FAA and Port must meet federal and state legal requirements — including Section 404 of the Clean Water Act and Washington's Growth Management Act — before any construction affecting wetlands can proceed. The document asserts that the EIS does not consider a broad enough range of alternatives, making it legally insufficient as a basis for approving the runway project.

    Sea-Tac International Airport Impact Mitigation Study: Initial Assessment and Recommendations — Section 9, Potential Socio-Economic Impacts and Mitigation

    A 1997 study commissioned by cities and institutions near Seattle-Tacoma International Airport found that airport operations depress nearby property values compared to similar homes elsewhere in King County, and that properties directly under flight paths suffer additional losses from noise, visual pollution, and reduced quality of life. Researchers compared single-family homes around Sea-Tac with comparable homes in Northwest King County (Shoreline area), using strict criteria to ensure fair comparisons. The study notes that while overall regional growth means nearby home values may still rise over time, they appreciate more slowly than they would without the airport's presence.

    Sea-Tac International Airport impact mitigation study: Initial assessment and recommendations

    A 1997 impact mitigation study found that the expansion of Sea-Tac International Airport, including a proposed Third Runway, would impose significant costs on surrounding communities — with Burien and Des Moines alone accounting for nearly 80% of an estimated $2.95 billion in mitigation needs. The study examined 26 specific environmental impacts across areas such as noise, air quality, and water quality, and recommended establishing a permanent noise monitoring program to ensure projected noise contours are not exceeded. It also called for a comprehensive South King County planning effort to balance the needs of communities, schools, hospitals, and the airport.

    Sea-Tac International Airport impact mitigation study: Initial assessment and recommendations – Appendix A: Equity issues and socio-economic impacts

    A 1997 study examined the unequal distribution of costs and benefits generated by Seattle-Tacoma International Airport, finding that while the airport's economic benefits (jobs, income, and travel services) spread across the broader Puget Sound region, its harms—including noise, traffic, and reduced property values—fell disproportionately on a small number of nearby cities: Burien, Des Moines, Federal Way, Normandy Park, and Tukwila. Data from a 1991 passenger survey showed that these five heavily impacted communities accounted for only 5.9% of home-originating enplanements, while King County as a whole contributed 57.2%. The study concluded that mitigation measures were needed to redirect some of the airport's regional benefits back to the communities bearing the greatest burden of its operations.

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.
