California Code, Public Utilities Code - PUC § 7555

No railroad corporation may use any street, alley, or highway, or any of the land, whether covered by water or otherwise, owned by any city or county, unless the right to do so is granted by a vote of the governing body of the city or county. If any railroad corporation operating within a city or county applies to the governing body of the city or county for a franchise or permit to cross any such street, alley, or highway, with main, branch, side, switching, or spur trackage, the governing body of the city or county, within a reasonable time, shall hold a public hearing upon the application after reasonable notice to the applicant and to the public and shall thereafter grant the franchise or permit applied for upon reasonable terms and conditions unless such governing body reasonably finds that the grant of the franchise or permit would be detrimental to the public interest of the city or county. Nothing in this section imposes any duty upon or limits the authority of, any city organized and existing pursuant to a freeholder's charter, or any officer thereof.
