In 1951, the City of Los Angeles acquired a 50-year lease for 1,700 acres in the northeastern section of what had once been a part of the old Encino Rancho and built the Sepulveda Dam Recreation Area (now known as the Sepulveda Basin Recreation Area). One of the largest open spaces in the San Fernando Valley, it features several large recreation areas, including parks, three golf courses, a model aircraft field, an Olympic velodrome, a Japanese garden, a wildlife refuge, a water reclamation plant, and an armory.
