A. The Commonwealth shall provide financial assistance to localities whose plans have been approved pursuant to subsection D of § 16.1-309.3 in quarterly payments based on the annual calculated costs which shall be determined as follows:
1. For community diversion services, one-half of the calculated costs as determined by the following factors: (i) the statewide daily average costs for predispositional nonresidential services and (ii) the total number of children in need of services and children in need of supervision complaints diverted at intake by the locality in the previous year and the total number of children who have been screened for needing community diversion or community-based services using an evidence-based assessment protocol.
2. For predispositional community-based services, three-quarters of the calculated costs as determined by the following factors: (i) the statewide daily average cost evenly divided for predispositional community-based residential and nonresidential services and (ii) the number of arrests of juveniles based on the locality’s most recent year available Uniform Crime Reports for (a) one-third of all Part 1 crimes against property, (b) one-third of all drug offenses and (c) all remaining Part 2 arrests.
3. For postdispositional community-based services for adjudicated juveniles, one-half of the calculated costs as determined by the following factors: (i) the statewide average daily costs for postdispositional community-based nonresidential services and (ii) the locality’s total number of juveniles, who, in the previous year, were adjudicated delinquent for the first time.
4. For postdispositional community-based services for juveniles adjudicated delinquent for a second or subsequent offense, one-half of the calculated costs as determined by the following factors: (i) the statewide average daily costs evenly divided for postdispositional community-based residential and nonresidential services and (ii) the locality’s total number of court dispositions which, in the previous year, adjudicated juveniles as (a) delinquent for a second or subsequent offense, (b) children in need of services, or (c) children in need of supervision, less those juveniles receiving services under the provisions of §§ 16.1-285.1 and 16.1-286.
B. Any moneys distributed by the Commonwealth under this article which are unexpended at the end of each fiscal year within a biennium shall be retained by the county, city or combination thereof and subsequently expended for operating expenses of Juvenile Community Crime Control Act programs. Any surplus funds remaining at the end of a biennium shall be returned to the state treasury.
