In the Salt Lake City Development thread we are discussing a site downtown between 400 and 500 South on Main ST.
One of the lines that stood out to me about what Amazon wants is "a business friendly environment." Salt Lake City is consistently ranked as one of the most business friendly cities.
We are also a growing tech market.
The site we are talking about is a whole block, undeveloped parking lot that sits squarely at a light rail station serving lines that go to the airport (about 30min by train), the University of Utah, downtown, Amtrak and into much of the suburbs. It is 8 min from the airport by car and bordered by two arterial roads: 400 South (with direct access to the University of Utah) and 500 South (a wide, one way street spilling onto I-15 and I-80 which are both less than a mile away.)
I know this is a long shot, especially because we are so close to Seattle but I think Amazon is looking for a low cost, large metropolitan area. Something along the lines of Austin, Salt Lake City or the research triangle.
