California Code, Welfare and Institutions Code - WIC § 1738

When the court commits a person to the authority the court may order him conveyed to some place of detention approved or established by the authority or may direct that he be left at liberty until otherwise ordered by the authority under such conditions as in the court's opinion will insure his submission to any orders which the authority may issue. No such person shall be transported to any facility under the jurisdiction of the Youth Authority until the director has notified the sheriff of the county of the committing court of the place to which said person is to be transported and the time at which he can be received.
