Not more than one-half of the public street shall be closed at any one time unless otherwise determined by the city engineer. Temporary access shall be provided for all owners. An open trench shall not exceed one hundred (100) feet in business and commercial districts or three hundred (300) feet in other districts unless authorized, in writing, by the city engineer. All trenches must be backfilled or covered up by nightfall at the direction of the city engineer.
