Cal. Welf. and Inst. Code § 233
The board of supervisors may by ordinance provide for the establishment, support, and maintenance of a delinquency prevention commission, composed of not fewer than seven citizens, to coordinate on a countywide basis the work of those governmental and nongovernmental organizations engaged in activities designed to prevent juvenile delinquency. If the board so elects, it may designate the juvenile justice commission, or any other committee or council appointed pursuant to Section 232 or 235, to serve in such capacity.
The commission may receive funds from governmental and nongovernmental sources to hire an executive secretary and necessary staff and to defray needed administrative expenses. The board of supervisors may direct any county department to provide necessary staff service to the commission. The commission may expend its funds on specific projects designed to accomplish its objectives.
Members of the delinquency prevention commission shall be appointed by the board of supervisors to serve a term of four years, and they shall be reimbursed for their actual and necessary expenses incurred in the performance of their duties. Upon a vacancy occurring in the membership in the commission and upon the expiration in the term of office of any member, a successor shall be appointed by the board of supervisors. When a vacancy occurs for any reason other than the expiration of a term of office, the appointee to fill such vacancy shall hold office for the unexpired term of his or her predecessor.
The board of supervisors may appoint initial members to any delinquency prevention commission created after the effective date of the amendment made to this section at the 1973-74 Regular Session of the Legislature to hold office for the following terms: one-half of the membership of an even-numbered commission for a term of two years and one-half plus one of the membership of an odd-numbered commission for a term of two years. The remaining initial members and the term of office of each successor appointed to fill a vacancy occurring on the expiration of a term thereafter shall be four years.
For a delinquency prevention commission existing on the effective date of the amendment made to this section at the 1973-74 Regular Session of the Legislature the board of supervisors may at any time upon the expiration of all the members' terms of office appoint members to hold office for the following terms: one-half of the membership of an even-numbered commission for a term of two years and one-half plus one of the membership of an odd-numbered commission for a term of two years. The remaining members and the term of office of each successor appointed to fill a vacancy occurring on the expiration of a term thereafter shall be four years.
Notwithstanding the preceding provisions of this section, the board of supervisors shall appoint two or more persons who are between 14 and 21 years of age to membership on a delinquency prevention commission, provided there are available persons between 14 and 21 years of age who are able to carry out the duties of a commission member in a manner satisfactory to the appointing authority.
