The permittee in the conduct of the work, use, or maintenance of an encroachment authorized by a permit issued pursuant to this chapter shall provide, erect, and/or maintain such lights, barriers, warning signs, patrols, watchmen, and other safeguards as are necessary to protect the traveling public. Any omission on the part of the city engineer to specify in the permit what lights, barriers, or other protective measures or devices shall not excuse the permittee from complying with all requirements of law and appropriate regulations and ordinances for adequately protecting the safety of those using public streets. If, at any time, the city engineer finds that suitable safeguards are not being provided, the city may provide, erect, maintain, relocate, or remove such safeguards as are deemed necessary or may cancel the permit and restore the right of way to its former conditions, all at the expense of the permittee.
A permittee making any excavation or erecting or leaving any obstruction within, under, or upon the right of way, or causing the same to be made, erected, or left, shall place and maintain lights at each end of the excavation or obstruction, at not more than fifty foot (50') intervals along the excavation or obstruction, from one-half (1/2) hour before sunset of each day to one-half (1/2) hour after sunrise of the next day, until the excavation is entirely refilled or the obstruction removed and the right of way made safe for use. In addition, reflectorized warning signs conforming to the requirements of the California division of highways shall be placed two hundred feet (200') and four hundred feet (400') from each excavation or obstruction, in such a position as to adequately warn public traffic.
The warning signs, lights and other safety devices shall conform to the requirements of section 465.7 of the Vehicle Code and of any sign manual issued by the department of public works of the state of California. (Ord. 994, 5-26-1970)
