It is unlawful to place, park or leave standing on any public street, alley or City-owned or City-controlled parking areas any object other than a motor vehicle, such as but not limited to construction equipment, materials or trash receptacles, without the approval of the Police Chief or Street Superintendent. Any such items placed are required to have adequate warning devices placed on the end nearest to any on-coming traffic. These devices may be reflective barrels or minimum “Type II” barricades. Any item found to be in violation of this section may be removed by whatever means necessary with all costs to be paid by the person responsible for the property.
