Cal. Sts. & Hy. Code § 11304
Not later than the hour set for hearing any person owning, or having any legal or equitable interest in, any real property which might suffer legal damage by reason of the establishment of the proposed pedestrian mall may file with the clerk of the legislative body a written claim of damages. Such written claim must describe the real property as to which the claim is made, must state the exact nature of the claimant's interest therein, must state the nature of the claimed damage thereto, and must state the amount of damages claimed. The failure to file such written claim within the time provided shall be deemed a waiver of any claim for damages or compensation and shall operate as a bar to subsequent action seeking to prevent the establishment of said pedestrian mall or to recover damages on account of such establishment. The filing of such claim shall operate as a bar in any subsequent action to the recovery of any damages or compensation in excess of the amount stated in such claim. Any such claim may be withdrawn by the claimant at any time by written withdrawal with the same effect as if it had never been filed.
