Begs the question on its location. Susanville is kind of split up between HWY 139 and 395 off HWY 36, so anybody's guess on its location? Seems like near the intersection of HWY 139 and HWY 36 could make sense, most likely in the Walmart/Safeway Parking lot near the Pizza Factory?. We visit there on a occasion but usually just to the downtown brewery for lunch. Speaking of locations.. The
Lassen Ale Works Boardroom is as good a site as any

..but highly unlikely.
I agree. The Walmart/Safeway Parking lot near the Pizza Factory is the best spot. That area has many commercial locations nearby and allows for other properties the Superchargers can be located. Rough distances (counter-clockwise order) are:
134 miles = Mt. Shasta - 134 Morgan Way, CA Supercharger
112 miles = Redding, CA
107 miles = Red Bluff, CA Supercharger
102 miles = Chico, CA Supercharger
85 miles = Reno - N Sierra St,, NV Supercharger
103 miles = Aruras, CA (CA-299 @ US-395)
200 miles = Klamath Falls, OR Supercharger (via a stop in Aruras, CA using US-395), and
169 miles = Klamath Falls, OR Supercharger (directly)
Not to mention that these towns and hamlets do not have staff that understand this sort of electrical infrastructure. I recall that when Lone Pine approved the permit for the Supercharger at the Film Museum, the city or county had to contract with a firm out of Los Angeles (or somewhere else) to do all the heavy lifting and inspections.
Indeed, many small agencies will contract out specialized functions and use consultants to provide staff augmentation. Some firms I am aware of are:
Services - CSG Consultants
Services - Harris & Associates
Coastland Civil Engineering
