Although not absolute, Lamar Advertising was awarded a victory over Rapid City's sign code last week. In his decision for Lamar Advertising's case against Rapid City, Judge Jeffrey Viken decided that Rapid City's ban on digital billboards conflicted with state law, so wasn't valid. He did not believe the sign code singled out Lamar or restrict its speech. A trial would be necessary to determine if the spacing requirements are too strict, or if Rapid City must pay attorneys' fees.
According to the Rapid City Journal, 66% of voters were in favor of the ballot initiative that banned new digital signs. The City Council will discuss Monday about appealing the decision or going to trial on the remaining issues.
UPDATE: According to a KOTA news story, the Rapid City Council chose to delay their decision on appealing the decision.
