16 stories?
How high is Manhattan above sea level? I always thought it was pretty close, so how they that deep without running into water I do not understand.Then again, I’m from Florida where it works like that a lot, maybe in New York it is all rocky and keeps the water out.

You answered your own question towards the end. Partially submerge a rock in water. This is Manhattan. Drill a hole into this rock, down past the water line. This is what you have in this picture.

And there's literally no cracks/gaps in the rock that would let water in?

There’s water in the picture. You just need to pump it out faster than it leaks in.

Sounds like a recipe for big problems.

Technology exists for this to occur and is widely used. The alternative is to not build anything. Or have LIRR tracks going over Park Ave in midtown.

Millions of gallons of water is pumped out of the subway system daily.

Manhattan exists and is able to support all the buildings in such close proximity because of the bedrock known as Manhattan schist. https://en.wikipedia.org/wiki/Manhattan#Bedrock
There are several places where the schist rises above the ground, or outcroppings so you can see what lies beneath. New York is essentially built on a rocky mountain.

This place is a schist hole.

Will schist talking in this thread ever end?

Oh no, do you find what these people are saying offensive? Better get a lawyer and drag them through the quartz.

Basalt! We're not igneous of the law.

No one is talking. You're schistophrenic.

I took a geology class once, and the professor told us the word to describe the intensity of the schist pattern in a rock is schistocity.

Manhattan is basically solid bedrock, much of it exposed (or was before being built up).

They're inside solid rock down there, same deal for our tunnels between Manhattan and LI or the mainland. They just go right down into the bedrock.
