If the owner of the land submits a sworn written statement denying responsibility for the presence of the vehicle on his land within such ten-day period, the statement shall be construed as a request for a hearing which does not require his presence. Notice of the hearing shall be mailed, by registered mail, at least ten days before the hearing to the owner of the land and to the owner of the vehicle, unless the vehicle is in such condition that identification numbers are not available to determine ownership. If such a request for hearing is not received within the ten days after mailing of the notice of intention to abate and remove, the city shall have the authority to abate and remove the vehicle or parts thereof as a public nuisance without holding a public hearing. (Ord. 1021 NCS §4; Ord. 887 NCS §1; prior code §15.16.8 (part).)
