The construction of a separate building for the insane was approved by the county board of supervisors on November 26, 1888.
[3][4] The asylum was rebuilt quickly after the fire, and a home for the county poor was added to the facility in 1918.
[11] It was closed on October 1, 1986, at which time the approximately 210 residents who were there were moved to the new Ridgewood Health Care Center.
[12] Asbestos removal in, then demolition of, High Ridge Health Care Center began in October 1988, to be completed by early 1989.
[13] The site is now a retail development known as High Ridge Centre, with only the old duck pond remaining from the former asylum.
