The new Expo Square LED video signs would be illegal under Title 42 Tulsa Revised Ordinances 60.100 if it were applied there. I know its County property but I thought the annexation in 2009 meant that the Expo and the Fairgrounds had to abide by city regulations?
They became operational this weekend with animated cartoons.
Section 60.100 Dynamic Displays
The supplemental regulations of this section apply to all signs with dynamic displays.
Except as otherwise expressly stated, these regulations apply whether incorporated in to off-premise outdoor advertising signs or on-premise signs that are allowed to include a dynamic display.
60.100-A
The images and messages displayed on a dynamic display must have a minimum dwell time of at least 8 seconds and may not contain any movement, animation, audio, video, pyrotechnics or other special effects.
60.100-B
The transition or change from one message to another must occur in one second or less and involve no animation or special effects.
60.100-C
The images and messages displayed must be complete in and of themselves within the required dwell time.
60.100-D
Dynamic displays may not be located within 50 feet of the driving surface of a signalized intersection, measured horizontally in a straight line from the nearest point of the sign structure to the nearest point of the intersection.There's more, but those should have been enough.
