It's really not a problem. Controlled blasting around vulnerable or weak structures is well studied and practiced by professionals. Computer aided design and modeling has only gotten better over the years.
NYC in particular has some very stringent regulations regarding blasting, allowable vibration levels, and so on. Long gone are the days of gung-ho cowboys lighting off fuses leading to piles of dynamite, massive fireballs, and the like.

E: Trying to find a paper about blasting a road tunnel in Turkey under some ancient ruins. The stringent restrictions they were under and the things they did to maintain compliance were really, really interesting (as a blasting engineer) but I can't find the damn thing right now.
