8-1-8: CONTRACTORS' OPERATIONS:
   A.   Dumping And Littering: No contractors shall allow any vehicle to operate out of any construction site, regardless of whether the same shall be operated by the contractor, their agents, employees or subcontractors, in such a manner as to dump, scatter or deposit any rubbish, stones, wire, earth, ashes, cinders, sawdust, hay, glass, manure, filth, paper, snow, ice, dirt, grass, leaves, twigs, shrubs, construction waste, garbage or other offensive or nauseous material on any street, alley or public place. The city is hereby empowered to order any contractor to take such precautions as deemed necessary to prevent any such foreign materials from being deposited on the streets, alleys or public places and to remove all foreign material on the street, alley or public place. If and in the event any contractor shall fail to comply with the order of the city, all construction may be ordered stopped.
   B.   Clean Vehicles: No contractor or other person shall permit a vehicle to enter upon a public street, alley, sidewalk or other public place without first having its tires and wheels cleaned so as not to litter or soil any street, alley, sidewalk or other public place; and having any material removed from the interior or exterior or vehicle body which might fall or be deposited upon any street, alley, sidewalk or public place by normal movement of vehicles in traveling over such places.
   C.   Keep Streets Litter Free: All streets, alleys, sidewalks or public places adjacent to any building or construction site shall be maintained in a litter free condition at all times. This shall include such soiling or littering caused by erosion, landslides or general construction activities at any such site.
   D.   Liability Of Contractor: Whenever a contractor is engaged in any construction or maintenance activity, it shall be the contractor's responsibility to see that the provisions of this section are not violated by the contractor, the contractor's agents, employees, subcontractors or haulers of materials and supplies. If more than one contractor or any governmental unit is involved in work which contributes to the littering of streets, alleys, sidewalks or other public places in the same site or area, they shall be separately and jointly responsible for compliance with the provisions of this section.
   E.   Cleaning Littered Street: If a street, alley, sidewalk or public place should become soiled or littered through any of the aforementioned means, the person responsible shall cause such soiling or littering to be cleaned up forthwith. If and when the person responsible fails to comply with any order to clean up or to take such precautions as deemed necessary to prevent foreign materials from being deposited on any street, alley or public place, then all ingress and egress to the site or area involved may be stopped until compliance with the order is effected.
   F.   Haul Routes: Any contractor or subcontractor, before starting construction or excavation, shall contact the city in regard to haul routes where all excess material will be disposed of. All haul routes shall be approved by the city. In the event the contractor or subcontractor fails to clean any portion of said haul route, said cleaning will be done by the street department and all such work hours will be charged against the contractor or subcontractor.
   G.   Exceptions: The provisions of this section shall not apply to construction work within the barricaded area of work being done in the street right of way pursuant to a city excavation permit authorizing the same, or to certain emergency or other work being performed within a barricaded area pursuant to a city contract or by certain emergency forces, provided that excavated material stored temporarily within the barricaded area shall not be scattered or carried or allowed to accumulate outside of such area.
