Any antenna or tower that, after the initial operation of the facility, is not used for the purpose for which it was intended at the time of filing the application for a continuous period of 12 months shall be considered abandoned. The wireless telecommunication carrier of such abandoned antenna or tower and ancillary wireless communication facilities shall remove the same within 90 days of receipt of a notice from the City notifying the owner or operator of such abandonment. Whenever a facility is abandoned or ceases operation, the entire facility shall be removed, including, but not limited to, all antennas, antenna supports, feeder lines, base stations, electronic equipment, and the concrete pad upon which the structure is located. Failure to remove such an abandoned facility shall result in declaring the antenna and/or tower a public nuisance. If there are two or more users of a single tower, then this section shall not become effective until all users cease using the tower. (Ord. 03-19 § 3 (Exh. B); Ord. 09-12 § 1 (Exh. A))
