Added Feb 2002 For SR 509 and new road to airport hearing & comments ALERT click here
Note EIS did NOT disclose known ASARCO contamination. Also note that the new road to the airport is PERFECT for terrorists to take out the fuel farm & aircraft and then make a fast get-away on the new SR509 that is in a FAA no build zone.

Where will the planes fly? Who will get insulation?

Special note to those of you that received the Port of Seattle  Update flyer (No 6 - Fall 2000) that shows we are "number one in total expenditure to date for noise abatement..."

The list combined all three New York airports as one airport yet did NOT combine all the King County operations. If we combine all of King County aircraft operations we are about the same as Chicago (O'Hare). That means we will actually one of the busiest, NOT 18th as reported by this flyer. Atlanta has MULTIPLE airports paying for mitigation. Dallas Forthworth is about 8 times larger than SeaTac. O'Hare has engine run up facilites. MInneapolis actualy shuts down a road if engine runups occur in one place to eliminate road traffic noise.

Another point, in their infinite wisdom, Seattle put a land locked airport in the heart of the biggest school district in the most densly populated County in the State. It did not provide any sound buffer zones to the sides and very little north to south.

A more meaningful statistic would be how many people are that were within 55 DNL had their houses bought or insulated. I use 55 DNL since the shrinking noise contours are due to software updates and do not correlate with real noise monitor readings.
