Take the 180 Jefferson entrance, EVSEs are in the back lot.
Used it on the way home from the San Carlos Art and Wine Festival on Saturday 10/6. Both ports on the fast charger were operational. The L3 charger is public and free. The five L2 chargers are public but not free. One or two are in handicapped parking spots. Security guard walked by while I was charging, which was comforting given the secluded location. I suggest avoiding the neighborhood on your way in or out, it's a little on the wild side. Stick to the major roads.
I would love to see a fast charger in or near San Francisco next.
