The city’s Housing Authority hopes to build 1,000 affordable apartments on vacant land in its complexes with private developers, its chairman revealed yesterday.

Requests for proposals and a list of potential sites will be ready early next year, John Rhea said at a breakfast meeting of the Association for a Better New York.

This “is a landmark in the evolution of NYCHA,” he said, adding that federal cuts were behind the search for funding sources with “stable, predictable cash flows.”

No one will be displaced and no building razed, he said of the fear that the largest US public housing agency could be privatized.

His plan got a quick endorsement from City Council Speaker Christine Quinn.
