Cal. Sts. & Hy. Code § 11402
Anything in this part to the contrary notwithstanding, nothing in this part shall be construed or interpreted as creating any right in any person to damages or compensation by reason of the establishment of a pedestrian mall, it being the intention of the Legislature in enacting this part to provide an orderly method for the determination and payment only of such damages and compensation as are required by the Constitutions of the State of California and the United States of America. In this connection the Legislature hereby expressly declares that it is its intention that to the extent to which the establishment of a pedestrian mall is justifiable as an exercise of the police power for which no compensation is constitutionally required, no damages or compensation shall be allowed in any action.
