Coal or other materials may be deposited in streets preparatory to delivery for use, provided, that such deposit does not reduce the usable width of the street or roadway at that point to less than eighteen feet (18'), and provided that such material or coal other than material used in actual building construction shall not be permitted to remain in 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. (1972 Code)
