Visited Monday Nov 20. Fast progress. Yes, it looks to me like raised platform is permanent. Note new style for Urban charger stalls. Second picture taken straight down from top level, showing excavation of HV electrical vault. Worker said depth will be 104". Transformer will probably be installed right next to it, pad poured at same time as walls of vault.
I could get no answer as to when they expect to be done. Conduit in concrete from top level to ground level seems to be in place, but more surface connecting conduit still awaiting installation. Cables to stalls still need to be laid in raceway above. 20 x 2 DC = 40 cables !
22 * 72kW = 1.58 MW not counting efficiency losses.
No sign of footings for solar canopy - bummer. Parking positions below top of parking structure are mostly dedicated to monthly pass holders, so not surprising that Tesla was only able to get roof top area. It is possible 2 stalls on ground floor will be special, not have to buy parking access, but disability access more likely, because no elevator.
My guess is this could be live in 10 days or a little more. Car from local Riverside electric utility on site.
