Tower System
a. 
The application submitted by the applicant to the Board of Appeals shall include: (a) a system design plan that shall include, at a minimum, radio frequency parameters, tower height, number and location of all antennas on the tower (proposed by the applicant and future co-locations), radio frequency output, effective radiated power and azimuth antenna type; (b) coverage map of the area to be served by the proposed tower; (c) coverage map showing coverage available under existing towers and other appropriate structures; and (d) an evaluation of the tower's relationship to the following: other antenna sites, existing buildings taller than 50 feet, and communication towers and water tanks within one mile of the proposed tower; and
b. 
The applicant for a new communications tower shall demonstrate to the Board of Appeals that co-location on existing towers or other appropriate structures is not feasible and that the proposed tower is the only feasible location for the antennas. Physical constraints and economic feasibility may be considered. Co-location shall be deemed not possible if:
i. 
planned equipment would exceed the structural capacity of existing and approved towers, considering existing and planned use of those towers, and such towers cannot be reinforced to accommodate planned or equivalent equipment at a reasonable cost;
ii. 
planned equipment will cause interference with other existing or planned equipment for that tower, and the interference cannot be prevented at a reasonable cost;
iii. 
existing or approved towers do not have space on which planned equipment can be placed so as to function effectively; or
iv. 
existing or approved towers will not provide effective signal coverage sought by the applicant; and
c. 
The applicant demonstrates that the tower is needed to introduce personal wireless service to an area that is without such service. The applicant shall submit a master plan for its proposed communications network for the entire county. The Department of Planning & Zoning shall adopt a policy outlining the submittal requirements for such a master plan; and
d. 
The applicant demonstrates that the proposed tower will not degrade or cause interference to the County's wireless communication systems which include, but are not limited to public safety, administrative and school wireless systems; and

b. 
The tower shall be constructed so as to provide capacity for future co-location of other commercial and/or government-operated antennas, unless the applicant demonstrates that such design is not economically or physically feasible. The system design plan shall delineate an area near the base of the tower to be used for the placement of additional equipment shelters or space for other users; and
c. 
All towers shall be of monopole construction and shall be screened or camouflaged to reduce visual obtrusiveness, including but not limited to the use of compatible building materials and colors, screening, landscaping, and placement within trees. Lattice towers may be permitted if the applicant demonstrates that it is not feasible to construct a monopole tower to a height that will provide adequate space for future co-locations and/or that a monopole could not provide the structural support necessary for the antennas proposed.
3. 
Tower Site
a. 
The tower shall be set back a distance equal to the height of the tower from all property lines except for adjacent properties under common ownership. Guy wires and accessory buildings must comply with the minimum setback requirements for the Zoning District within which the tower is located. The Board of Appeals may reduce this requirement if the goals of this Section would be better served thereby; and
b. 
If the tower is not camouflaged or screened from adjacent properties and the road by existing vegetation, buildings or structures, it shall be surrounded by a minimum 40-foot wide buffer of dense tree growth and understory in all directions to create an effective year round visual buffer. Trees and vegetation may be existing on the subject property or installed as part of the proposed facility or a combination of both. Existing mature tree growth and natural contours of the site shall be preserved to the maximum extent possible. The vegetated buffer shall be of sufficient height and depth to effectively screen the base of the tower and all equipment and equipment shelters. The Department of Planning and Zoning shall determine the types of trees and plant materials based on site conditions; and
