A one-acre park on the roof of the World Trade Center's vehicle security center, dubbed Liberty Park, has been in the works for some time, but the Port Authority wasn't saying much about it until all the details were finalized. The Port Authority's cover was blown, however, when architect Santiago Calatrava released renderings of his design for the rebuilt Church of St. Nicholas, which first appeared on the Tribeca Citizen and revealed an outline of what the park would look like. Since then, the park's designer, landscape architect Joseph E. Brown, has been more forthcoming, elaborating details of the design to the Times. Sitting 25 feet above Liberty Street with a panoramic view of the National September 11 Memorial, the park will feature around 40 trees and shrubs, a small amphitheater-like elevated space, and a large staircase paralleling Greenwich Street with wooden benches on its landings. It will be accessible from Battery Park City via the West Street pedestrian bridge, and from a ramp on Greenwich Street. There will also be stairways at two other corners. Perhaps most notably, the Liberty Street facade will feature a 300-foot-long, 20-foot-high "living wall" made of various types of vines and ivy.
