(a) 
No person shall place, maintain, or display upon or in view of any highway, street or alley any unauthorized sign, signal, marking or device which purports to be or is an imitation of or resembles an official traffic-control device or railroad sign or signal, or which attempts to direct the movement of traffic, or which hides from view or interferes with the effectiveness of any official control device or any railroad sign or signal.
(b) 
No person shall place or maintain nor shall any public authority permit upon any highway, street or alley any traffic sign or signal bearing thereon any commercial advertising.
(c) 
This section shall not be deemed to prohibit the erection upon private property adjacent to highways, streets or alleys of signs giving useful directional information and of a type that cannot be mistaken for official signs.
(d) 
Every such prohibited sign, signal or marking is hereby declared to be a public nuisance, and the sheriff, compliance officer or city official is hereby empowered to remove the same or cause it to be moved without notice.
(Ordinance 9105 adopted 9/13/92; 1998 Code, sec. 10.203)

(a) 
The mayor or any person designated by him or her of the city is hereby designated as the person who shall place and maintain traffic-control signs, signals and devices when and as required for proper traffic control in the city as he or she may deem necessary to regulate the traffic under [this chapter or] any other traffic ordinance of the city or under state law.
(b)

All traffic-control signs, signals, devices and markings heretofore placed or erected by the city or the mayor and now in use for the purpose of regulating, warning or guiding traffic are hereby affirmed, ratified and declared to be the official traffic-control devices, provided such traffic-control devices are not inconsistent with the provisions of the state law.
(Ordinance 9105 adopted 9/13/92; 1998 Code, sec. 10.206)
Proof, in any prosecution for a violation of this chapter or any traffic ordinance of the city, that any traffic-control device, sign, signal or marking was actually in place on any street shall constitute prima facie evidence that the same was installed by the mayor or any person designated by him or her pursuant to the authority of this chapter and the ordinance directing the installation of such device, signal or marking since it is unlawful for any person other than the mayor or any person designated by him or her, acting pursuant to an ordinance of the city, to install or cause to be installed any signal, sign or device purporting to direct the use of the streets or the activities on those streets or pedestrians, vehicles, motor vehicles, or animals.
