Cal. Bus. & Prof. Code § 19489
A license issued under this article is not transferable nor does it permit the conduct of a horse racing meeting at any track not specified therein.
If, however, the track specified in a license becomes unsuitable for racing because of fire, flood, or other catastrophe, the meeting or any remaining portion thereof may be conducted at any other track specified by the board in the same area. The board may specify any other track within the area for the conduct of the meeting, whether or not such conduct would result in increasing the number of racing days in the county or area in which such track is situated. Before any other track is so specified, the board shall obtain the consent of the person licensed to conduct a meeting at the track which has become unsuitable for racing and of the owners and operators licensed to conduct a meeting at such other track.
