Four state institutions include one in the Capital Region, that provide care for the disabled will be closed over the next four years in the ongoing shift to group homes and community settings. The Office for People With Developmental Disabilities, responsible for about 126,000 New Yorkers with developmental disabilities, says the O.D. Heck Developmental Center in Schenectady is slated to shut by March 31, 2015. The closings are also for institutions in Brooklyn, Binghamton, and Queens. The agency has closed 14 of its 20 institutions over the past 25 years. That's reduced the number of residents from nearly 27,000 to fewer than 1,000.
