I found this article dated June 7, 2016 but couldn't find previous reference to it here at TMC:

Council members voted unanimously to approve a resolution allowing Tesla Motors to build and operate an electric supercharger station at the Arlington Convention Center located at 1200 Ballpark Way. A total of 10 parking spaces will be designated for Tesla vehicles or those with compatible charging technology. The project will cost approximately $250,000, of which Arlington will pay $150,000 as part of a grant to invest in energy alternatives.
