Not any time soon because the bedrock for mounting a foundation is too far below the surface from about 30th down to Canal to be a smarter economical move than building in midtown or lower manhattan.
Is this an urban legend? Certainly the bedrock is farther down. But bedrock isn't needed to build skyscrapers. Modern piling can rely entirely on friction from the surrounding soil rather than sitting on top of a solid subterranean layer.

Deeper foundations do cost more but that cost wouldn't be prohibitive, especially when compared to all the other costs associated with building in manhattan.

My bet is that zoning restrictions are the reason. City planners try to factor in infrastructure and transportation capacities along with the obvious NIMBY issues.

less than 15 floors to go until topping out! But one question, why cant they just have an observation deck on the 105th floor and put the telecommunicational stuff below that? They can put a viewing area on the roof like the south tower. by the way get some more update photos rolling in from different angles.
The reason why SOM rejected an observatory platform at the parapet was not because of communication equipment risk, but rather the fact that this tower is self contained, 4 water cooling towers will be located at the roof; also, the window washing crane and its track will take hell alot of space.

It was historically the reason, hence the proliferation of skyscrapers in midtown and downtown - but better building technology has now surpassed this problem. This has allowed some tall buildings to be built within these districts already - such as the Trump Soho.
