Amazon.com Inc. has circled back to revisit or re-contact a handful of cities on its list of potential locations for its $5 billion second headquarters – and a report on those follow-ups doesn’t mention Denver.

Denver is on a list of 20 potential sites for the sprawling “Amazon HQ2” campus announced in January. The e-retail giant says the campus – similar in scale to its main headquarters in downtown Seattle – could employ as many as 50,000 high-paid employees.

Amazon officials visited the Mile High City in February and had dinner with Gov. John Hickenlooper.

A report Friday from The Wall Street Journal, says Amazon executives have made follow-up visits to some of the finalist locations.

Says the WSJ:

“The visits over the past couple of months include New York City, Newark, N.J., and Chicago, according to people familiar with the matter. In addition, Amazon has been following up with other locations, including Miami and the Washington, D.C.-area, according to some of the people.”

The story does not mention the Mile High City.

Local leaders who bid on HQ2 have been quiet about the process in recent months. Officials, led by the Metro Denver Economic Development Corp., have been secretive about key details of their bid, such as what incentive offers were discussed and which specific sites in and around Denver were proposed.

Colorado Politics has reached out to J.J. Ament, CEO of the Metro Denver EDC, for comment; we’ll add it when we hear from the agency.

The WSJ report comes after last month’s analysis by tech-news site GeekWire that said Amazon has concentrated its recent hiring for office jobs in the D.C. area, Boston and New York City, filling far fewer jobs in Denver.

Amazon CEO Jeff Bezos owns a home in Washington and also owns The Washington Post newspaper.

One piece of good news for Denver – “good,” that is, if you think landing HQ2 and its hordes of workers would be a good thing – is that, per the WSJ, Amazon seems to be “favoring an urban site,” which could rule out suburban locations on its list like northern Virginia and Montgomery County, Maryland.

Amazon has said it plans to announce its favored location sometime this year. But the Journal says Amazon is “still in negotiations with several cities and hasn’t yet completed a deal with any one location. They said the company may negotiate near-final deals with several of them before announcing its ultimate selection, something that could help avoid signaling its choice prematurely.”

Nathan Jensen, a professor of government at the University of Texas at Austin, had this to say to CNN:

“The key for Amazon is that they want to build a second HQ that is an attractive place to live and work for young professionals. This is why quality of life in the city will matter.”
