The rock under Manhattan is particularly difficult (schist with some spots sporting other metamorphic rock that's three or four times harder than concrete) to tunnel through.

Thats not right. Underground could be as little as $200 million a mile if you include reasonable non-US examples. Above ground could be as low as $50-80 million a mile. Thats all excluding right of ways.
One point to note is that the fee structure for the North Branch Corridor Fund (to pay for zoning change / density boost) is more localized than the NOF. Its something like 40% towards local infrastructure. So if Sterling is paying something like $100-$150 million, $60 million could be going straight back to a transit system.
Now the trick is the city shouldnt let them claim that as "their contribution;" thats their fee to the city and therefore the city's contribution. Their contribution, since the primary beneficiary is them, should be in addition.
