Battery Park City is a mainly residential  planned community at the southwestern tip of the island of Manhattan in New York City, New York, United States, more than of which is parkland. The land in Lower Manhattan upon which it stands was created by land reclamation on the Hudson River using over 3 million cubic yards of soil and rock excavated during the construction of the World Trade Center, the New York City Water Tunnel, and certain other construction projects, as well as from sand dredged from New York Harbor off Staten Island. The neighborhood, which is the site of Brookfield Place (formerly the World Financial Center), along with numerous buildings designed for housing, commercial, and retail, is named for adjacent Battery Park.
