The redevelopment of Randall’s Island parks was the largest city-funded initiative in over a century. The island contains vital park land that needed facility development, park maintenance, and environmental restoration. Since 2000, RZAPS has collaborated with the Randall’s Island Park Alliance and created the redevelopment master plan, including playing fields, natural open spaces, a waterfront and various recreational additions. RZAPS also realized several buildings, such as Icahn Stadium and the Tennis Center.
