(c) A county or group of counties may develop an agreement with the Department of Human Services to reduce their number of commitments of juvenile offenders, excluding minors sentenced based upon a finding of guilt of first degree murder or an offense which is a Class X forcible felony as defined in the Criminal Code of 2012 , to the Department of Juvenile Justice, and then use the savings to develop local programming for youth who would otherwise have been committed to the Department of Juvenile Justice. A county or group of counties shall agree to limit their commitments to 75% of the level of commitments from the average number of juvenile commitments for the past 3 years, and will receive the savings to redeploy for local programming for juveniles who would otherwise be held in confinement. For any county or group of counties with a decrease of juvenile commitments of at least 25%, based on the average reductions of the prior 3 years, which are chosen to participate or continue as sites, the Redeploy Illinois Oversight Board has the authority to reduce the required percentage of future commitments to achieve the purpose of this Section. The agreement shall set forth the following: (1) a Statement of the number and type of juvenile offenders from the county who were held in secure confinement by the Illinois Department of Juvenile Justice or in county detention the previous year, and an explanation of which, and how many, of these offenders might be served through the proposed Redeploy Illinois Program for which the funds shall be used;(2) a Statement of the service needs of currently confined juveniles;(3) a Statement of the type of services and programs to provide for the individual needs of the juvenile offenders, and the research or evidence base that qualifies those services and programs as proven or promising practices;(4) a budget indicating the costs of each service or program to be funded under the plan;(5) a summary of contracts and service agreements indicating the treatment goals and number of juvenile offenders to be served by each service provider; and(6) a Statement indicating that the Redeploy Illinois Program will not duplicate existing services and programs. Funds for this plan shall not supplant existing county funded programs. In a county with a population exceeding 2,000,000, the Redeploy Illinois Oversight Board may authorize the Department of Human Services to enter into an agreement with that county to reduce the number of commitments by the same percentage as is required by this Section of other counties, and with all of the same requirements of this Act, including reporting and evaluation, except that the agreement may encompass a clearly identifiable geographical subdivision of that county. The geographical subdivision may include, but is not limited to, a police district or group of police districts, a geographical area making up a court calendar or group of court calendars, a municipal district or group of municipal districts, or a municipality or group of municipalities.
