Lamar Adver. of S.D., Inc. v. Zoning Bd. of Adjustment
Annotate this Case
Lamar Advertising submitted applications to Rapid City for sign building permits, which would allow Lamar to convert six traditional billboards to digital signs. The City denied Lamar's applications, finding that a conditional use permit was required to alter an existing off-premises sign. Lamar petitioned the circuit court for a writ of certiorari, arguing (1) the City, in at least 100 prior instances, allowed Lamar to alter existing signs without first obtaining a conditional use permit, and therefore, the City should be estopped from now requiring a conditional use permit; and (2) the City's denial was beyond its jurisdiction as an effort to improperly regulate digital billboards in contravention of existing ordinances. The circuit court denied Lamar's petition. The Supreme Court reversed, holding that the City acted in an irregular pursuit of its authority when it denied Lamar's six applications for sign building permits.
