Welf. & Inst. Code, § 1859

Where any such youth correctional center is established, and where the minimum standards and qualifications provided for in Section 1857 have been complied with by the county, the State of California through the Youth Authority, out of any money appropriated for this purpose, shall reimburse the county at the rate of two hundred dollars ($200) per month per person being supervised by the youth correctional center during the first six months of such person’s first-time participation in the center program. This amount shall be adjusted annually, upward or downward, by the Director of Finance in accordance with the proportionate increase or decrease in per capita costs for supervising Youth Authority wards in institutions and on parole.

Whenever a claim made by a county pursuant to this section covering a prior fiscal year is found to have been in error, adjustment may be made on a current claim without necessity of applying the adjustment to the appropriation for the prior fiscal year.
