I'm here at the SC now.
They are installing six, as surmized earlier. Two are adjactent the existing equipment and the existing pull forward in stalls, and the new stalls are both back in stalls, and four new stalls are across the driveway spanning a whole bay of four stalls. All six pedestal stubs are up, four across driveway already concreted into place, and ditch across driveway filled.
I took many pictures, but posting them won't cause net probable benefit now.
All existing stalls are operational (lit up), but #5A is being used for construction work space, so unavailable; the rest were in use and working.
My guess is all construction will be finished in under a week, before the holiday, but lately delay from construction complete to turn on has been significant, however, they may be going faster for the recent push.
