"they hauled out so much rocky debris from under Grand Central that it could have covered Central Park...almost a foot deep."

Didn't they use it to extend southern Manhattan, IIRC the trade center and Battery Park used to be under water

That extension was done with landfill from the original WTC excavation in the 70's.

I know a lot of this project's rock came out in Long Island City. You used to be able to see the exit pit on the N train curve on the approach to Queensboro Plaza.

Battery Park City came from the WTC excavation but The Battery itself was also landfill that came from street widening and stuff like that going back to the mid 1800s. The original western edge of lower Manhattan was essentially Greenwich Street all the way up to about 15th St in the Meatpacking District. (So the WTC site was indeed once underwater, but idk if that land came from Grand Central or not).

Can’t find any info on that but they’re certainly doing a lot of work on Manhattan’s shores that have been using lots of rock and dirt. Everything from the restoration of the East River shoreline in the East Village and Lower East Side, to Gansevoort Peninsula, has used quite a lot.

"And when they're all completed, estimated for 2019, they will bring subway and commuter rail service to vast, underserved stretches of the city, particularly the far East and West sides of Manhattan." lol
