It is unlawful to deposit on any public sidewalk any material which may be harmful to the pavement thereof, or any waste material, or any glass or other articles which might cause injury to persons, animals, or property.
Merchandise or other articles may be deposited on sidewalks preparatory to delivery, providing that the usable width of the sidewalk is not thereby reduced to less than four feet; and provided, that no such article remains on such walk for more than one-half hour.
(Prior code § 18.119).
