Crain is speculating on probable development to occur on the parking lot that's behind the Detroit Club and Free Press building on Fort and Cass. What's interesting is that the Detroit Club and the parking lot (which also has underground spaces but don't seem to be used) are up for auction (both by Uralli) but the parking lot is currently at a higher bid than the Detroit Club.
As of this post, the parking lot and Detroit Club are at $2 million and $1.2 million respectively. That seems like a lot for a small parking lot and probably why Crain is speculating on it.
