Why would this destroy the neighborhood, though? It will only enhance the neighborhood... create mixed income residences, park space, great views and amenities, more retail and street life, more jobs for the city.
It's being so "isolated" should be viewed as a good thing to those that don't want to see the good areas around it change. Sure, they'll be more traffic, but it's not like there's none now. This is NYC.
This is really like a continuation of the Downtown area, which needs to be developed.
It's taking nothing, literally, and making a huge asset for the city.
