There you go. Plenty of room as I said. IOA on the plot in question. To scale.
Obviously the shape of a future park could be made to fit the plot and it may not have such a large lagoon.
Room for parking too, though i'd assume the existing parking structures would also be expanded as per their design and be connected to any new development via the proposed people moving system.
Also, as with developments over I-4, it isn't as if nothing has been talked about with existing property owners and the city. Because they have been doing. For a few years now.
So why couldn't this happen again?
