Dear Washington State Elected Officials,

There is a 2018 budget proviso currently proposed by Representatives Mike Pellicciotti and Tina Orwall for an Airport Impact Study, I ask you all to support it.

Sea-Tac International Airport has been the fastest growing airport in the United States for several years and the 6th fastest growing airport in the world. Add Sea-Tac's major expansion plan and the removal of thousands of trees either for "safety" or the Port's own property development, trees that were in fact planted under the FAA's own 1978 "Airport Landscaping for Noise Control". A program which was cancelled by the FAA without reason and more importantly without consideration to the impacts on the surrounding communities, but cancelled nonetheless by the FAA in 2010.

More than 21 years have passed since the last airport impact mitigation study was completed and the airport has more than doubled in traffic since. Yet, an aggressive Century Plan has been released, one that outlines a growth at Sea-Tac International Airport with passenger capacity at 66 million and cargo expansion at approximately 750,000 cubic metric tons. Did you know that this is more passenger traffic than Dallas Fort Worth had in 2016? This is also the same cargo demand as Dallas Fort Worth. Did you know that Dallas Fort Worth has 7 runways and is over 17,000 acres, bigger than the island of Manhattan? I am sure you all know that Sea-Tac International Airport is on only 2,500 acres, yet the Port of Seattle has plans to grow at an unimaginable rate, an amount of air traffic that undoubtedly will pressurize the communities below in both noise and health impacts.

It is simply illogical to think an airport the size of Sea-Tac at 2,500 acres with 3 runways can accomplish the same amount of air traffic as Dallas Fort Worth with 7 runways and over 17,000 acres. How can this growth plan even be considered without a full impact mitigation study?

As a voter, resident, and community member impacted daily by the airport, I ask that you strongly support Representative Pellicciotti and Representative Orwall's Airport Impact Study budget proviso. It is simply the correct measure for each and everyone of you to stand behind.

A link to a draft of the proviso language can be found here:


This study must be conducted in partnership with the State of Washington and surrounding airport cities, with absolutely no financial support from the Port of Seattle.

A track record of action is an honorable legacy, please do not let this impact study fall through the cracks on your watch. We the surrounding communities need this, our children deserve this.

Thank you.
