A. Open trenching shall not be allowed on paved streets unless the permit holder or person in charge has exhausted all possibilities to force, drill, jet or tunnel under the street. Permits, when allowed, to open trench in paved areas, must include an approved construction design and time schedule for completing the work.
B. Included in the design shall be provision for sawing pavement. Jackhammers or pavement breakers may only be used for emergency repair work with resawing to follow.
C. All excavated material must be removed. A select material approved by the city must be imported and compacted in lifts to maximum density obtainable.
D. Pavement bases and AC pavement must be replaced at least equal to the original construction but in no case may the roadway section have less than eight inches (8") of base material and three inches (3") of AC pavement.
E. Sealing of construction joints must be accomplished after placement of the final patch.
F. No trench may be left unattended for any length of time while open.
G. Temporary or permanent patches must be placed no more than forty eight (48) hours after closing of the trench. Temporary patches must be used where weather or other problems would cause delays beyond forty eight (48) hours in placing permanent patches. Removal of temporary patches and placement of permanent patches are the responsibility of the permit holder.
H. Failure of any portion of the trench construction or pavement shall be repaired at the permit holder's expense.
I. Proper barricades and signs must he provided by the permit holder to afford the public the least possible inconvenience. Closing of streets for any period of time will only be granted in circumstances where this method of construction appears to be the only available solution within reason.
J. Any work requirements not carried out or corrected promptly will be resolved by the city and any costs involved shall be charged to the permit holder. (1978 Code)
