A. 
The city engineer is directed to install and maintain official traffic signals at those intersections and other places where traffic conditions are such as to require that the flow of traffic be alternately interrupted and released in order to prevent or relieve traffic congestion or to protect life or property from exceptional hazard.
B. 
The city engineer shall ascertain and determine the locations where such signals are required by field investigations, traffic counts, consultation with other departments, and other traffic information as may be pertinent, and his/her determinations therefrom shall be made in accordance with those traffic engineering and safety standards and instructions set forth in the traffic manual issued by the State Department of Transportation or as approved by the city council.
C. 
Whenever the city engineer installs and maintains an official traffic signal at any intersection, street name signs shall likewise be erected and maintained at such intersection clearly visible to traffic approaching from all directions, unless such street name signs have previously been placed and are maintained at any such intersection.

The city engineer is authorized to mark center lines and lane lines upon the surface of the roadway to indicate the course to be traveled by vehicles and may place signs temporarily designating lanes to be used by traffic moving in a particular direction, regardless of the center line of the street or highway.
(Ord. 592 § 1, 1998)
The city engineer is authorized to place and maintain distinctive roadway markings, as described in the California Vehicle Code, on those streets or parts of streets where the volume of traffic of the vertical or other curvature of the roadway renders it hazardous to drive on the left side of such markings or signs and markings.

(Ord. 592 § 1, 1998)
It is unlawful for any person to place, maintain or display any sign or device upon or in view of a street which purports to be, is an imitation of, or resembles an official warning or direction sign or signal, or which in any other manner attempts to direct the movement of traffic or the actions of operators without authority.
