I may have misunderstood...but, didn't the CC say that an eastward expansion is also out?!?
Just spitballing here...but, why doesn't the city buy the land for the South Central Waterfront District and build a new CC there with a waterfront park and other civic amenities. We already know the neighborhoods are going to come out in force against tall buildings there anyway. Plus, the future blue line will run right up against it.
As soon as the new CC is complete, the city will then parcel off and sell the old one, reconnect the downtown grid and opening all that area up to new developments. Yes, I know, the "CC" hotels won't like it. But, since it was brought up, the Javitz Center doesn't not have any huge, major CC hotels near it. I visited that center annually (pre-COVID) and I never really minded that my hotel was blocks and blocks away. And, there's nothing that says a new hotel (and multifamily) could not be apart of a new development there. Heck, the current vision calls for those.
Just an idea.
