835.07 Adjustments

Adjustments to the standards of Section 835 may be granted under either of the following circumstances:

  1. A gap in the applicant's service exists and that gap can only be alleviated through the adjustment of one or more of the standards of this section. If an adjustment is to be approved, the applicant must demonstrate the following:
    1. A gap in coverage or capacity exists in the wireless telecommunication provider's service network that results in network users being regularly unable to connect, or maintain connection, with the provider's network;
    2. The proposed wireless telecommunication facility will fill the existing service gap. Filled means the proposed facility would substantially reduce the frequency with which users of the network are unable to connect, or maintain connection, with the provider's network; and
    3. The gap cannot be filled through collocation on existing facilities, or establishment of facilities that are consistent with the standards of this section on properties other than the proposed site or on the proposed site in a manner which does not require an adjustment.
  2. The proposed adjustment would utilize existing site characteristics to minimize demonstrated or potential impacts on the use of surrounding lots. Site characteristics include, but need not be limited to, those identified in Subsection 1203.03(B). The adjustment must result in a lower level of impact on surrounding lots than would result if the standard were not adjusted. In considering the requested adjustment, the following may be considered:
    1. Visual impacts;
    2. Impacts on view;
    3. Impacts on property values; and
    4. Other impacts that can be mitigated by an adjustment so that greater compliance with Subsection 1203.03(D) occurs.

835.08 Abandonment

  1. Wireless telecommunication facilities will be considered abandoned when there has not been a provider licensed or recognized by the Federal Communications Commission operating on the facility for a period of 365 consecutive days. Determination of abandonment will be made by the Planning Director, who shall have the right to demand documentation from the facility owner regarding the tower or antenna use.
  2. Upon determination of abandonment, the facility owner shall have 60 calendar days to reuse the facility or transfer the facility to another owner who will reuse it within 60 calendar days of the determination of abandonment.
  3. If the facility is not reused within 60 calendar days of the determination of abandonment, county authorization for the use shall expire. Once authorization for the use has expired, the facility operator shall remove the facility from the property within 90 calendar days. If the facility operator does not remove the facility within 90 calendar days, the county may remove the facility at the expense of the facility operator, or, in the alternative, at the property owner's expense.
