A. General: The following provisions shall govern the issuance of special use permits:
1. If the tower or antenna is not a permitted use under section
12-11A-4 of this article or permitted to be approved administratively pursuant to section
12-11A-5 of this article, then a special use permit shall be required for the construction of a tower or the placement of an antenna in all zoning districts.
2. In granting a special use permit, the governing authority may impose conditions to the extent the governing authority concludes such conditions are necessary to minimize any adverse effect of the proposed tower on adjoining properties.
3. Any information of an engineering nature that the applicant submits, whether civil, mechanical, or electrical, shall be certified by a licensed professional engineer.
B. Information Required: Each applicant requesting a special use permit under this article shall submit a scaled site plan and a scaled elevation view and other supporting drawings, calculations, and other documentation, signed and sealed by appropriate licensed professionals, showing the location and dimensions of all improvements, including information concerning topography, radio frequency coverage, tower height requirements, setbacks, drives, parking, fencing, landscaping, adjacent uses, and other information deemed by the governing authority to be necessary to assess compliance with this article.
C. Factors Considered In Granting Special Use Permits: The governing authority shall consider the following factors in determining whether to issue a special use permit, although the governing authority may waive or reduce the burden on the applicant of one or more of these criteria if the governing authority concludes that the goals of this article are better served thereby:
1. Height of the proposed tower;
2. Proximity of the tower to residential structures and residential district boundaries;
3. Nature of uses on adjacent and nearby properties;
4. Surrounding topography;
5. Surrounding tree coverage and foliage;
6. Design of the tower, with particular reference to design characteristics that have the effect of reducing or eliminating visual obtrusiveness;
7. Proposed ingress and egress; and
8. Availability of suitable existing towers and other structures as discussed in subsection D of this section.
D. Availability Of Suitable Existing Towers Or Other Structures: No new tower shall be permitted unless the applicant demonstrates to the reasonable satisfaction of the governing authority that no existing tower or structure can accommodate the applicant's proposed antenna. Evidence submitted to demonstrate that no existing tower or structure can accommodate the applicant's proposed antenna may consist of any of the following:
1. No existing towers or structures are located within the geographic area required to meet the applicant's engineering requirements.
2. Existing towers or structures are not of sufficient height to meet the applicant's engineering requirements.
3. Existing towers or structures do not have sufficient structural strength to support applicant's proposed antenna and related equipment.
4. The applicant's proposed antenna would cause electromagnetic interference with the antenna on the existing towers or structures, or the antenna on the existing towers or structures would cause interference with the applicant's proposed antenna.
5. The fees, costs, or contractual provisions required by the owner in order to share an existing tower or structure or to adapt an existing tower or structure for sharing are unreasonable. Costs exceeding new tower development are presumed to be unreasonable.
6. The applicant demonstrates that there are other limiting factors that render existing towers and structures unsuitable.
E. Setbacks And Separation: The following setbacks and separation requirements shall apply to all towers and antennas for which a special use permit is required; provided, however, that the governing authority may reduce the standard setbacks and separation requirements if the goals of this article would be better served thereby:
1. Towers must be set back a distance equal to the height of the tower from any off site residential structure.
2. Towers, guys, and accessory facilities must satisfy the minimum zoning district setback requirements.
3. In zoning districts other than industrial or heavy commercial zoning districts, towers over ninety feet (90') in height shall not be located within one-fourth (1/4) of a mile from any existing tower that is over ninety feet (90') in height.
F. Security Fencing: Towers shall be enclosed by security fencing not less than six feet (6') in height and shall also be equipped with an appropriate anticlimbing device; provided, however, that the governing authority may waive such requirements, as it deems appropriate.
G. Landscaping: The following requirements shall govern the landscaping surrounding towers for which a special use permit is required; provided, however, that the governing authority may waive such requirements if the goals of this article would be better served thereby:
1. Tower facilities shall be landscaped with a buffer of plant materials that effectively screens the view of the tower compound from adjacent residential property. The standard buffer shall consist of a landscaped strip at least four feet (4') wide outside the perimeter of the compound.
2. In locations where the visual impact of the tower would be minimal, the landscaping requirement may be reduced or waived altogether.
3. Existing mature tree growth and natural land forms on the site shall be preserved to the maximum extent possible. In some cases, such as towers sited on large wooded lots, natural growth around the property perimeter may be a sufficient buffer. (2005 Zoning Code)
