This site planning sample shows the equipment layout on the secure parking area.
"Parking is the act of stopping and disengaging a vehicle and leaving it unoccupied. Parking on one or both sides of a road is often permitted, though sometimes with restrictions. Parking facilities are constructed in combination with some buildings, to facilitate the coming and going of the buildings' users. ...
Parking facilities include indoor and outdoor private property belonging to a house, the side of the road where metered or laid out for such use, a parking lot (North American English) or car park (British English), indoor and outdoor multi-level structures, shared underground parking facilities, and facilities for particular modes of vehicle such as dedicated structures for cycle parking."
