    Request to advertise for construction bids for the 2010 Airfield Improvement Projects – Contract 2 CIP 100172

    In January 2010, the Port of Seattle sought approval to advertise construction bids for environmental cleanup work tied to the Seattle-Tacoma International Airport Third Runway project, including removing the 160th Street box culvert, restoring Miller Creek, and converting temporary stormwater ponds into permanent detention facilities. The estimated $6.6 million project was already funded within the previously approved Third Runway budget through Passenger Facility Charges and bond proceeds, requiring no new funding authorization. The work was required to fulfill federal and state permit conditions before the overall Third Runway project could be formally closed out.

    Seattle-Tacoma International Airport air monitoring

    This 2009 report summarizes air quality monitoring studies conducted near Seattle-Tacoma International Airport between 1996 and 2002, following concerns raised during the airport's expansion planning. Measurements of carbon monoxide, nitrogen dioxide, particulate matter, and air toxics were taken at multiple sites around the airport, and none of the pollutants exceeded federal air quality standards. While some elevated levels of metals like chromium were detected at the Sea-Tac monitoring site, overall cancer risk from air toxics was lower than the regional average for the Seattle area.

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.
