Enforcing the paid spots is going to be interesting.
Do they give you any kind of tag to display in your car? If not, there's no way of knowing who's using the paid parking without paying (since they likely don't want any vigilante justice going on, I'm sure they won't have tags). The reserved spots are only set aside until 10am, so they'd have to have someone at each lot by 10am to hand out the tickets/towing.
They'll either have to install a card-controlled gate that opens itself at 10am every morning, or hire someone with a plate scanner to sit at each station from 2-10am every day.
Also, unless they have some sort of instant enforcement, it won't help someone who has paid for a spot if there aren't any available when they enter the lot.
