    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 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.

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.
