2. Freshkills Park
You might think that all of Freshkills Landfill on Staten Island is just garbage (true, there is 150 million pounds of it), but one of the mounds was formed primarily from debris extracted from the wreckage of the first World Trade Center. On this, James Corner, landscape architect of the High Line, will build an earthwork reflecting the shapes of the towers on their sides in the conversion of the landfill into a massive park.
