The Department of Developmental Services operates five state-owned and operated 24-hour care facilities, and two state-operated 24-hour leased facilities. The five state-owned Developmental Centers (DCs) are Agnews DC (Santa Clara County), Fairview DC (Orange County), Lanterman DC (Los Angeles County), Porterville DC (Tulare County), and Sonoma DC (Sonoma County). These facilities comprise approximately 5.2 million gross square feet on 2,153 acres. Leased facilities include Sierra Vista (Sutter County) and Canyon Springs (Riverside County). The seven facilities are used to aid the Department's mission to provide medical, dental, and nursing care; supervision; active treatment; education and vocational training for residents with developmental disabilities. Additionally, Porterville DC serves consumers referred through the state's judicial system. Due to declining population, the Legislature has approved a plan to close Agnews by June 30, 2008, and closure activities are underway.
