Aren't most blocks in midtown owned in pieces by several developers? It's not so likely that a complete lot would be owned by one developer so with that in mind, I just think it would be more reasonable to put in a slightly higher FAR.
Even if a developer acquires rights to a whole block like in this case, the block's dimensions are still only 40,000 sq feet, limiting lots like this to 1.2 Million Sq Feet.

I don't know the specific dimensions or land use details but it seems that a building like 1 Liberty Plaza would have a higher FAR than 30. I just know that building has around 2,000,000 sq feet.
