NEW YORK CITY — Cleveland-based Forest City Enterprises and Greenland USA, a subsidiary of Shanghai-based Greenland Group Co., have partnered to develop Atlantic Yards, a 22-acre residential and commercial real estate development in Brooklyn. The joint venture covers both phases one and two of the project, including infrastructure, a permanent MTA rail yard, a platform above the rail yard, future residential units and future commercial high-rise development. The initial joint venture does not include the Barclays Center and B2 BKLYN, the first residential tower. Under the agreement, Greenland USA has acquired 70 percent of the project and will co-develop the project with Forest City, with both companies sharing all project costs going forward in proportion to their ownership interests. Forest City Ratner Companies, the New York-based subsidiary of Forest City, will co-manage the daily activities and develop project consistently with the approved master plan along with Greenland USA. The project will bring 6,430 residential units, including 2,250 units of affordable housing, to the Brooklyn area.
