Ordinance No. 2007-21 Page 7 Local spacinq requirements c6~ld interfere with the equal opportunity to use such technoloqies and are not included. Without those requirements. however. there is the potential for numerous dynamic displavs to exist alonq any roadway. if more than one dynamic displav can be seen from a qiven location on a road. the minimum displav time becomes critical. If the display time is 'too short. a driver could be subiected to a view that appears to have constant movement. This impact would obviouslv be compounded in a corridor with multiple siqns. If dynamic displays become pervasive and there are no meaninqfullimitations on each siqn's ability to chanqe frequently. drivers may be subiected to an unsafe deqree of distraction and sensory overload. Therefore, a lonqer display time is app,ropriate. " ." A constant messaqe is typicallv needed on a siqn so that the public can use it to identify and find an intended d,estination. Chanqinq messaqes detract from this way- findinq purpose and could adversely affect drivinq conduct throuqh last-second lane chanqes, stops, or turns. which could result in traffic accidents. Accordinqlv. dynamic displavs qenerallV stioul~ not be allow~d to OCCUpy the ~ntire COpy and qraphic area of a siqn. . In conclusion. the city finds that dynamic displavs should be allowed on siqns but with siqnificant controls'to minimize their proliferation and t,heir potential threats to public safety. b) Requlations. Dynamic displays on siqns are allowed subiect to the followinq conditions: 1) Dvnamic displays are allowed on Iv on monument and pylon siqns for conditionallv permitted uses in residential districts and for all uses in other districts. Dynamic displays may OCCUPY no more t~an 35 percent of t~e actual COpy and qraphic area. The remainder of the sign must not have the capabilitv to have dynamic displays even if not used. Only one. contiquous dynamic display area is allowed on a siqn face; 2) A dynamic display may not chanqe or mo~e more often than once every 20 minutes. except one for which chanqes are necessary to correct hour-and-minute. . date. or temperature information. Time. date. or temperature information is considered one dynamic display and may not b~ I,ncluded as a comp~nent of any other dynamic display. A display of time, date. orte~peratur~ must remain for atleast 20 minutes befOre chanqinq to a different displaYl but the time, date, or temperature information itself may chanqe no more often than once every three seconds; 3) The imaqes and fnessa~.es displayed must b~ static. and the transition The ctricken language is deleted; the underline~ language is inserted. 54
