The Port Authority of New York and New Jersey has released renderings of what will be "Liberty Park." The one-acre park, designed by landscape architect Joseph E. Brown, will be built 25 feet above Liberty Street and when completed in 2015 will allow for a panoramic view of the National September 11 Memorial. Beyond the views, the park will also provide a roof for the trade center's "vehicle security center," serve as a court for St. Nicholas Greek Orthodox Church, and will also include seating for up to 750 people. Brown's plans call for a living wall, a small amphitheater, and a balcony near the church, but the plans may change from the initial renderings. The estimated cost for this project is $50 million but that too may change as the plans mature.
