15,500-Apartment Co-op to Rise in Bronx
By THOMAS W. ENNIS
A cooperative housing development with 15,500 apartments will be built on a 300-acre tract in the Baychester area of the northeast Bronx.
It will be financed with a $263 million mortgage loan provided by the state under its Mitchell-Lama middle-income housing program.
The development, tentatively named Co-op City, will have a population estimated to total 55,000 to 60,000 persons. Its sponsor is the United Housing Foundation, a nonprofit organization that has built a number of large housing cooperatives for middle-income families here.
The site is bounded by the Hutchinson River Parkway, the New England Thruway and the Hutchinson River. The Freedomland amusement park has occupied under lease a 150-acre section of the tract. The operators of Freedomland, which is in bankruptcy, are attempting to stay in business by moving to an adjacent site of 30 acres.
Officials of the United Housing Foundation say Co-op City will be the world's largest apartment development, including any built in the Soviet Union since World War II.
