Each designated community mental health and developmental disability agency shall determine the need for community mental health and developmental disability services within the area served by the agency and shall thereafter prepare a local community services plan which describes the methods by which the agency will provide those services. The plan shall include a schedule for the anticipated provision of new or additional services and shall specify the resources which are needed by and available to the agency to implement the plan. The community services plan shall be reviewed annually. (Added 1979, No. 108 (Adj. Sess.), § 3; amended 2005, No. 174 (Adj. Sess.), § 47.)
