All material excavated from trenches and piled adjacent to the trench or in any street shall be piled and maintained in a manner as not to endanger pedestrians or users of the streets, and so that as little inconvenience as possible is caused to those using streets and adjoining property. Where the confines of the area being excavated are too narrow to permit the piling of excavated material beside the trench, such as in a narrow alley, or where a dangerous condition may be created, the City Engineer shall have the authority to require that the excavator haul the excavated material to a storage site and then rehaul it to the trench site at the time of backfilling. It shall be the excavator's responsibility to secure the necessary permission and make all necessary arrangements for all required storage and disposal sites. Proper barricading shall be set up and maintained in accord with the latest edition of the MUTCD.
All material excavated shall be laid compactly along the side of the trench and kept trimmed to cause as little inconvenience as reasonably possible to vehicular and pedestrian traffic, or as specified by the City Engineer. Whenever necessary to expedite the flow of traffic or to abate the dirt or dust nuisance, tow boards or binds may be required by the City Engineer.
The maximum length of open trench permissible at any time shall be not more than five hundred (500) linear feet or no more than one block, but in any case, no greater length shall be open for pavement removal, excavation, construction, backfilling, patching and all other operations without the prior written permission of the City Engineer.
