A. Pursuant to the Vehicle Code, whenever the City Council determines, upon the basis of an engineering and traffic survey, that a greater speed would facilitate the orderly movement of vehicular traffic and would be safe upon any street otherwise subject to a prima facie limit of twenty-five (25) miles per hour under the Vehicle Code, the City Council shall determine and declare a higher prima facie speed limit. When such determination has been made, the City Council shall by resolution direct the City Engineer to erect and maintain signs upon such street as provided in the Vehicle Code indicating file appropriate prima facie speed limit. Such signs may be supplemented by appropriate pavement markings.
B. Removal. Whenever the City Council, upon the basis of a traffic engineering investigation, finds that the conditions for which a speed limit has been determined as provided in Subsection A. of this Section no longer exist, the City Council shall by resolution direct the City Engineer to remove such signs and markings from such street.
