The public works department, through its traffic engineer or other responsible official may, in accordance with the city’s traffic code or as otherwise permitted by law, limit or prohibit turns to or from driveways giving access to arterial streets by requiring the placement of official traffic control devices when it appears that there is inadequate corner clearance, sight distance or driveway spacing; or when traffic capacity, delay or safety conditions require such prohibitions. The cost of the traffic control devices shall be borne by the owner of the parcel. [Ord. 8760 § 8, 1979].
