Underground park looks to provide NYC relief

New York City is home to one of the most iconic skylines in the world, but in an area as densely populated as Manhattan, finding space away from the fast-paced metropolis is becoming increasingly difficult. One project is exploring an innovative solution - an underground park in the abandoned Delancy Street subway station. The proposed 60,000 square foot public park, based on a pioneering light technology by architects James Ramsey and Dan Barasch, must first gain the approval of more than a dozen city and state planning authorities before it can be implemented.
