It shall be unlawful to deposit on any street any material which may be harmful to the pavement thereof, or any waste material or any glass or other articles which may do injury to persons, animals or property.
Coal or other materials may be deposited in streets preparatory to delivery or use, provided that such deposit does not reduce the usable width of the roadway at the point to less than eighteen feet (18'), provided that such material or coal, other than material to be used in actual building construction, shall not be permitted to remain on such street for more than three (3) hours.
Any such material or coal shall be guarded by lights if the same remains upon any street after nighttime. (M.C. 1962, sec. 13.114)
