alt Hacker NewsMaybe true in an area that requires redevelopment to grow, but in Raleigh there are huge, huge swaths of totally undeveloped land that are now much more valuable even within the same zones. You do not need ultra-high density towers to create true urban density.
I think you're setting up a false premise there about towers? Not sure where that came from.
Can you show me land that is now much more valuable than before? I suspect the places you're thinking of aren't really changing on value or buildability the way you expect.
