Cal. Government Code § 14076.4

If the board and the department enter into an interagency transfer agreement pursuant to Article 5 (commencing with Section 14070), for an initial period, that begins with the transfer of responsibilities from the department to the board and continues for a three-year period subsequent to the completion of the track and signal improvements between Sacramento and Emeryville, the San Francisco Bay Area Rapid Transit District General Manager and the district’s administrative staff shall, if that district has appointed members to the board in accordance with Section 14076.2, provide all necessary administrative support to the board to perform its duties and responsibilities, and may perform for the board any and all activities that they are authorized to perform for the district. At the conclusion of the initial period, the board may, through procedures that it determines, select the San Francisco Bay Area Rapid Transit District or another existing public rail transit agency for one three-year term immediately following the initial period, and thereafter for five-year terms, to provide all necessary administrative support staff to the board to perform its duties and responsibilities.
