4-1-8: TRAFFIC CONTROL:
   A.    Authority To Install Traffic Signals:
      1.    Ordinance Authorization: The general manager shall have the power and duty to place and maintain, or cause to be placed and maintained, official traffic control devices when and as required by the provisions of this chapter to make effective such provisions.
      2.    Vehicle Code Authorization: Whenever the California Vehicle Code requires, for the effectiveness of any provisions thereof, that traffic control devices be installed to give notice to the public of the application of such laws, the general manager is hereby authorized to install, or cause to be installed, the necessary devices, subject to any limitations or restrictions set forth in the laws applicable thereto.
      3.    General Manager Determinations: The general manager may also place and maintain, or cause to be placed and maintained, such additional traffic control devices as he may deem necessary or proper to regulate traffic or to guide or warn traffic; provided, however, he shall make such determination only upon the basis of traffic engineering principles and traffic investigations and in accordance with such standards, limitations, and rules as may be set forth in this chapter or as may be determined by ordinance or resolution of the board.
      4.    Stop Signs: Whenever any ordinance or resolution of the district designates and describes any street, or portion thereof, as a through street, or any intersection at which vehicles are required to stop at one or more entrances thereto, the general manager or his authorized representative shall erect and maintain stop signs on each and every street intersecting such through street, or portion thereof, so designated, at those entrances to other intersections where a stop is required; provided, however, stop signs shall not be erected or maintained at any entrance to an intersection where such entrance is controlled by an official traffic control signal. Every such sign shall conform with, and shall be placed as provided in the California Vehicle Code.
   B.    Lane Markings: The general manager is hereby authorized to mark centerlines 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 centerline of the highway.
   C.    Roadway Markings: The general manager is hereby 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 or the vertical or other curvature of the roadway renders it hazardous to drive on the left side of such markings or signs and markings. Such markings or signs and markings shall have the same effect as similar markings placed by the department of public works of the state pursuant to provisions of the California Vehicle Code.
