DOCUMENT. From the Stanford Branner Earth Sciences Library 1971 Geologic report of the Seal Cove-Moss Beach Area by F. Beach Leighton and Associates.
Lawsuit: 1975 Kopetzke v. County of San Mateo, Board. of Supervisors. “Since the exercise of police power was proper, it did not constitute a taking and no compensation is due. Chicago, Burlington & Quincy Railway Co. v. Illinois, 200 U.S. 561, 26 S. Ct. 341, 50 L. Ed. 596 (1906). To the extent plaintiffs’ losses result from any inherent geologic defects in their properties, the ancient rule of caveat emptor must apply. And to the extent their losses result from the regulatory activities of the Board based on the geologic findings of the Leighton Report, they constitute the unequal burden which citizens are frequently called upon to bear in the interests of the general welfare. Hadacheck v. Sebastian, supra.“
