Drive-ins and similar establishments shall have receptacles wherein all papers; containers and other litter are deposited and which comply with the standards for litter receptacles and authorized private receptacles, depending upon their use. It is unlawful for proprietors to permit conditions whereby loose litter accumulates and is blown to adjoining property. They shall promptly retrieve such litter and secure it in proper receptacles. Upon their failure to do so, the city may gather up the litter so deposited and the proprietor shall pay for the cost thereof. [Ord. 8573 § 15(Q), 1977].
