NYS Department of Environmental Conservation

625 Broadway is located in the 100-year flood plain

It should be noted that NYS Department of Environmental Conservation headquarters at 625 Broadway is built in the 100 year flood plain (shown in orange; red is the 500 year flood plain).

That means it has a more then 1 in 4 chance of flooding in any 30 year period. If the building had been privately financed it would require the purchaser to buy flood insurance to get a FHA-backed mortgage under federal regulations.
