This doesn't necessarily preclude them, but a thing to note about underground utilization in NYC: the city has absolutely no idea what's beneath its surface, in part due to centuries of development with nonexistent or inaccurate recordkeeping.
Burying trash receptacles rather than reusing parking spaces may be cheaper, but it isn't guaranteed. It may also vary by borough (Queens in particular has less underground infrastructure).
Yes we absolutely need those. But they will still reduce parking spaces. This is an unavoidable fight, and one that vast majority of non-far-outer-borough New Yorkers who don't drive need to win.
