There is definitely a Supercharger coming to Fountain Valley! It is being built now at the Costco Center off MacArthur Blvd. The exact location is at the South end of the PetSmart store near the corner of MacArthur Blvd and Newhope St. I went by the area yesterday and there is construction fencing around the site in the parking lot and a row of framing for the chargers.
