The Devil himself is forcing you to adopt a new sign code. You've got three options, lest the souls of everybody in your community burn for all eternity.
1) Every business must display a Canadian-style portable sign, minimum size 32'^2, with a 0' setback from the public ROW. That means if there's 30 tenants in a shopping center, all of them must display a Canadian-style portable sign, 10 medical practices in a medical office building? 10 black portables from the Great White North.
Think of this ...
... times 10 or 20.
2) Every business must have an electronic message center, with the display set in full Vegas mode; constant transitions, animation, blinking, chasing, and the like. Minimum size of the display: 32'^2, minimum height 10'.
Basically, this everywhere.
3) Freestanding on-premises signs are prohibited. However, full size (672'^2) billboards must be placed at intervals of 300' along both sides of all major and minor arterials. Minimum height - 40'.
35 of these every mile. (Too lazy to do the metric conversion now.)
Pick your visual pollutant.
