(A) The permittee shall take appropriate measures to assure that during the performance of the excavation work, traffic conditions as near normal as practicable shall be maintained at all times so as to cause as little inconvenience as possible to the occupants of the abutting property and to the general public, provided that the City Manager may permit the closing of streets and alleys to all traffic for a period of time prescribed by him, if in his opinion it is necessary.

(B) The permittee shall maintain safe crossings for two lanes of vehicle traffic at all street intersections where possible and safe crossings for pedestrians at intervals of not more than three hundred feet. If an excavation is made across a public street, alley or sidewalk, at least one safe crossing shall be maintained when possible for vehicles and pedestrians. If the street is not wide enough to hold the excavated material without using part of the adjacent sidewalk, a passageway at least one half of the sidewalk width shall be maintained along the sidewalk line.

(C) It shall be the duty of every person making an excavation in or upon any public place to place and maintain barriers and warning devices necessary for safety according Oregon Department of Transportation specifications. Warning signs shall be placed far enough back of the construction operation to alert traffic within a public street, and cones or other approved devices shall be placed to channel traffic, all in accordance with Oregon Department of Transportation specifications. The permittee shall notify the city when the public street is again usable to traffic. He shall see that all barriers are removed at this time so that normal traffic routing can proceed. Barriers shall meet Oregon Department of Transportation specifications.

(D) Warning lights shall be electrical markers or flashers used to indicate a hazard to traffic from sunset of each day to sunrise of the next day. Electrical markers or flashers shall emit a light at sufficient intensity and frequency to be visible at a reasonable distance for safety. Reflectors or reflecting materials may be used to supplement, but not replace, light sources.

(E) The permit for a street excavation may require that the permittee give notification to various public agencies and to the general public. In such case, the permit shall not be valid until the notice is given.
