Ordinance No. 2007- Page 7 potential for numerous dynamic displays to exist along any roadway. if more than one dynamic display can be seen from a given location on a road the minimum display time becomes critical. If the display time is too short a driver could be subjected to a view that appears to have constant movement, This impact would obviously be compounded in a corridor with multiple signs. If dynamic displays become pervasive and there are no meaningful limitations on each sign's ability to change frequently drivers may be subjected to an unsafe degree of distraction and sensory overload. Therefore, a longer display time is appropriate. A constant message is typically needed on a sign so that the public can use it to identify and find an intended destination. Changing messages detract from this way - finding purpose and could adversely affect driving conduct through last- second lane changes, stops or turns, which could result in traffic accidents. Accordingly dynamic displays generally should not be allowed to occupy the entire copy and graphic area of a sign. In conclusion, the city finds that dynamic displays should be allowed on signs but with significant controls to minimize their proliferation and their potential threats to public safety. b) Regulations. Dynamic displays on signs are allowed subject to the following conditions: 1) Dynamic displays are allowed only on monument and pylon signs for conditionally permitted uses in residential districts and for all uses in other districts. Dynamic displays may occupy no more than 35 percent of the actual copy and graphic area. The remainder of the sign must not have the capability to have dynamic displays even if not used. Only one, contiguous dynamic display area is allowed on a sign face. 2) A dynamic display may not change or move more often than once every 20 minutes, except one for which changes are necessary to correct hour - and - minute, date, or temperature information. Time, date, or temperature information is considered one dynamic display and may not be included as a component of any other dynamic display. A display of time, date, or temperature must remain for at least 20 minutes before changing to a different display, but the time, date, or temperature information itself may change no more often than once every three seconds, 3) The images and messages displayed must be static, and the transition from one static display to another must be instantaneous without any special effects; 4) The images and messages displayed must be complete in themselves, The stricken language is deleted; the underlined language is inserted. -7
