The new headquarters, according to Amazon, will bring up to 50,000 well-paying jobs and $5 billion in investment to whichever city the company chooses. In return, Amazon is seeking enough space to build up to 8 million square feet of office in a concentrated area, and tax breaks and other economic incentives.
The Crystal City area and the Rosslyn-Ballston corridor fit the bill for many of the things Amazon is seeking, especially a talented workforce and transit connections, though the real estate is likely a bit more expensive than Amazon is hoping for.
