Any wireless communication facility that has been discontinued or not in operation for a period of one year shall be considered abandoned. The owner shall then report in writing such discontinued use within fourteen (14) days to the Planning Director. Abandoned facilities shall be completely removed by the property owner and/or support tower owner within 180 days from the date of abandonment, and the site shall be re-vegetated. If such WCF is not removed within the 180-day removal period, the governing authority may remove the WCF at the owner’s expense.
