I found something interesting but not definitive in Baker when searching the
San Bernardino County permits database:
B201702580 applied date 4/19/2017
B201702581 applied date 4/19/2017
B201702583 applied date 4/19/2017
The site is 72157 Baker Blvd, which is "The World's Tallest Thermometer". Do other level 3 charging systems have an equipment enclosure like superchargers? 3 concrete dispensing islands could be a 12-stall pull-through supercharger design, and the $150,000 valuation on the permit works for a supercharger. The Thermometer opens at 10 AM - if someone wants to call them maybe you can get more information.
