The Department of Corrections (DOC) assumes a three month lag between the measures effective date and the date first offenders may be received. Included in the cost estimates in the table above are funds that would be distributed to the community corrections departments of counties for the costs of probation, post-prison supervision, and local control. The estimated length of stay is assumed to be approximately 11 months in a DOC facility at a marginal cost per day of $23.41. The estimated length of stay in local control is approximately 2 months, with an estimated 18 months of probation. The cost per day estimate for local control and probation is $10.72 per offender.
