Visited on September 13, charger was already occupied.
The parking is reserved for teachers during school hours. One of the space is designated with EV symbol, but there's no clarification to say whether that replaces the general rules, or adds to them.
There's another big sign at the entrance, but I think that's regarding the school grounds in general, not the parking.
I'm not certain whether the cable is attached or not. Based on the color I assume it belongs to the car and not the station. But the charger pedestal includes handles to hang cables.
