Protect our communities from the impacts of expansion at Sea-Tac Airport

  • We pledge our best efforts to compel the Airport to obey the environmental rules that are supposed to govern the construction of the third-runway embankment. Construction work & ordinary operations at the Airport continue to contaminate the streams that flow from its campus through neighboring communities & into Puget Sound, in violation of the permits that supposedly protect us. Safe, clean water is a vital concern to the communities near the Airport.
  • Trucks bringing fill to the runway embankment are a clear & well-documented safety hazard. They are conspicuously speeding, tailgating, clogging intersections, running yellow and red lights, and operating far above legal maximum weights, with loads that are not secure. Safety on the roads is critical.
  • There is nothing being planned to deal with the new noise that will be felt under the flight path for the third runway (if it is completed). Planning for noise mitigation is needed NOW, especially for the schools that will experience major overflight noise for the first time.
  • Property values continue to be hammered by the Airport; a new runway flight path will make a bad situation worse. This issue needs to be addressed soon, & responsibly.

Stop The Third Runway At Sea-Tac Airport

This project is an economic, environmental, and social disaster. Its estimated cost has gone from $221 million to $773 million. But the runway would be much too short for larger departing planes. Supporting infrastructure, and other building plans bring the total cost of renovating this airport into the range of $ 7 to $ 10 billion, by Airport estimates. And all of this adds no new capacity!

  • The expansion plan commits all our air-transportation resources into one overcrowded airport, and will set back the region’s real long-term air-transportation planning for decades.
  • The construction site contains 18 to 20 acres of wetlands, which would be destroyed. Huge amounts of fill (27 million tons) would rest on, and threaten, an aquifer. The plans for dealing with polluted run-off are inadequate. In fact, the damage would be irreparable.
  • The only plan for mitigation of noise from the new runway is to buy more near-by houses. This provides no relief for the tens of thousands who will be newly exposed to overflight noise in neighborhoods miles away from the Airport. The Airport still has not dealt adequately with the noise impacts of its second runway.
