    block in footprint

    I have trouble understanding the following in red.

    Within a year, a rough design was hashed out, and their vertical farm could feed a heck of a lot more than just 2% of New York's population. "One thirty-story building," says despommier, "one square New York block in footprint, could feed fifty thousand people a year. One hundred fifty vertical farms could feed everyone in New York City."

    Please let me know more easily how large it is. What does "footprint" mean there? Is it saying the New York block has as much space as one thirty-story building?

    Thank you.

    Re: block in footprint

    The "footprint" is how much space something takes up. What they are saying is that one building which was the size of a NYC block and thirty stories high could feed 50,000 people.
