Baychester, Bronx in the context of "Bronx Community Board 12"

The East Bronx is the part of the New York City borough of the Bronx which lies east of the Bronx River; this roughly corresponds to the eastern half of the borough. Neighborhoods include: Baychester, Castle Hill, City Island, Co-op City, Country Club, Eastchester, Edenwald, Edgewater Park, Harding Park, Morris Park, Parkchester, Pelham Bay, Pelham Parkway, Soundview, Throggs Neck, Van Nest, Wakefield, Westchester Square, and Williamsbridge.

The East Bronx is less densely populated than the West Bronx. While the West Bronx is older and its underlying Fordham gneiss is very hilly, the East Bronx is not only later-settled but also underlain by younger schist and in most parts flat and coastal, much like the neighboring borough of Queens. The East Bronx was annexed by the City of New York decades later; the West Bronx in 1874, while the East Bronx remained part of Westchester County until 1895.

Co-op City (short for Cooperative City) is a cooperative housing development located in the northeast section of the borough of the Bronx in New York City. It is bounded by Interstate 95 to the southwest, west, and north and the Hutchinson River Parkway to the east and southeast, and is partially in the Baychester and Eastchester neighborhoods. With 43,752 residents as of the 2010 United States census, it is the largest housing cooperative in the world. It is in New York City Council District 12.

Co-op City was formerly marshland before being occupied by an amusement park called Freedomland U.S.A. from 1960 to 1964. Construction began in 1966 and the first residents moved in two years later, though the project was not completed until 1973. The construction of the community was sponsored by the United Housing Foundation and financed with a mortgage loan from New York State Housing Finance Agency.
