Cal. Gov. Code § 14072.2

The joint powers authority, known as the Southern California Regional Rail Authority, may, if the authority elects to be a party to an interagency agreement pursuant to Article 5 (commencing with Section 14070), be expanded to form an authority for the administration of intercity passenger rail services in the Counties of Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, San Luis Obispo, Santa Barbara, and Ventura. The expanded authority may include, but is not limited to, the following agencies: the Imperial Valley Association of Governments, the Los Angeles County Metropolitan Transportation Commission, the Orange County Transportation Authority, the Riverside County Transportation Commission, the San Bernardino Association of Governments, the San Diego Association of Governments, the San Luis Obispo Council of Governments, the Santa Barbara County Association of Governments, and the Ventura County Transportation Commission. For the purposes of this section, “authority” means the expanded board of the Southern California Regional Rail Authority. Only the expanded board or authority, not the Southern California Regional Rail Authority board existing on July 1, 1996, may exercise jurisdiction over intercity rail matters for the service area of the authority. For purposes of taking action on intercity rail issues, including, but not limited to, equipment, funding, legislation, marketing, and operations, the member agency from each county shall be allowed one vote. Representation shall be limited to one agency per county.
