1. Applicant Review: The commission or hearing examiner may consider whether existing WCFs operated by the applicant in Blaine County, including within the incorporated cities, or on state or federally administered lands by a permittee, have obtained necessary permits from the governing jurisdiction, before any new permit for the applicant is granted. If the applicant has not obtained the required permits from the appropriate jurisdiction, the commission or hearing examiner may require the applicant to obtain other required permits as a condition of approval for any new permit issued by the county.
2. Alternative Sites: Alternative site and/or design studies provided by the applicant shall demonstrate that reasonable consideration has been given to such alternative sites and/or designs, and the proposal is the preferred alternative when considered in light of the purposes and intent of this chapter.

8. Parking Requirements: Adequate off street parking to accommodate maintenance and construction workers may be required.
a. The applicant shall demonstrate in writing that they have authority to access the WCF site for construction and maintenance purposes from a public right of way, across privately and publicly owned lands. Said written authority shall include the right of county officials to cross said lands for legitimate public purposes.
b. The applicant shall demonstrate that the site can be safely accessed by county officials and fire protection personnel.
10. Facility Upgrade: At the time of modification or upgrade of facilities, existing equipment shall be replaced with equipment that does not increase the facility's overall visual impact.
B. Design And Siting Standards:
1. Visibility: The WCF shall be designed to eliminate, to the greatest extent possible, the visibility of the proposed facility as viewed from a reference road, Wood River trail system, or State Highway 75 as it passes through a municipality by means of concealment, camouflage, disguise and placement. While complete elimination of any visual impact cannot be accomplished in every case, the applicants shall make every available effort to ensure that the visibility of the proposed WCF is slight. Techniques that can be used to potentially eliminate the visual impact include, but are not limited to, the following:
a. Selection And Use: Selection and use of antennas, support structures and configurations which result in the least bulk, profile and height possible;
b. Concealment: Concealment of the WCF within or on a structure, building, or edifice when said structure, building or edifice is compatible and in scale with the surrounding land uses and structures. Examples are:
(1) Church steeples, flagpoles, weather vanes and cupolas, etc.;
(2) Buildings and structures designed to look like typical agricultural buildings or structures such as windmills, silos, or barns, provided the building or structure housing the WCF is accessory to a permitted use on the same parcel;
(3) Buildings and structures designed to look like typical residential accessory structures such as garages and storage buildings, provided the building or structure housing the WCF is accessory to a permitted use on the same parcel; or
(4) Artificial features (such as synthetic rock) which is made to appear as a naturally occurring form in the environment;
c. Camouflage Or Disguise:
(1) Colors and materials for the WCF chosen to minimize visibility of the WCF;
(2) A WCF located on a building, wall or roof, designed to blend with the existing building's architecture by painting or shielding with material which is consistent with the design features and materials of the building;
(1) Locating the WCF, where it is backdropped by existing structure(s) or geographical feature(s) such as a hillside or building, sufficient that the profile of the WCF as viewed from a reference road, Wood River trail system or State Highway 75 as it passes through a municipality is eliminated to the greatest extent possible;
(2) Locating the WCF within an dense growth of trees of similar height;
(3) Roof mounted on a nonresidential building;
(4) Attached to the facade of a nonresidential building or structure;
(5) Attached to a utility pole (see subsection 9-3-16-13E of this chapter). 2. Scale: The WCF shall be designed and constructed to be in scale with the surrounding land uses and structures as exhibited by relative height, mass and proportion.
a. A WCF shall not be artificially lighted, except as needed for routine maintenance of the facility. Exterior lighting shall utilize:
(1) Minimum wattage necessary for the proposed use,
(2) Full cut off lighting fixture whereby light is downcast, and does not extend horizontally beyond the base of the fixture, and
b. WCFs which are required to be illuminated by a local, state or federal agency shall be reduced in height and/or otherwise modified or located so as to not require lighting. No lighting other than for routine maintenance of the facility is permitted.
4. Security Barriers: A security barrier may be required by the building official, commission or hearing examiner to be erected no closer than twenty five feet (25') around the perimeter of ground mounted WCFs. In the case of a roof mounted WCF, a security barrier may be required around the antenna and support structure(s) or antenna array. Security barriers shall be maintained by the operator of the WCF or mount for the life of the installation. Security barriers shall be constructed of nonreflective material.
5. Equipment Vaults, Sheds And Structures: Equipment vaults, sheds and structures shall satisfy at least one of the following requirements:
a. Placed underground; or
b. Disguised, camouflaged, painted, fenced or screened with vegetation so that visibility of the equipment vault, shed or structure as viewed from a reference road, Wood River trail system or State Highway 75 as it passes through a municipality is mitigated as required under subsection B1 of this section.
a. Aboveground equipment for WCFs exclusive of roof and facade attached WCFs shall not generate noise in excess of 50 decibels (db) at the property line.
b. Roof or facade attached equipment for WCFs shall not generate noise in excess of 50 db at ground level at the base of the structure closest to the antenna and support structure(s).
C. Design Standards For Utility Pole Mounted WCFs: In addition to complying with the standards of evaluation as set forth in this section, utility pole mounted WCFs shall satisfy the following design standards:
1. One Permitted: Only one WCF shall be permitted on any one utility pole.
2. Concealed Or Camouflaged: The antenna and mounting bracket shall be either fully concealed within the street pole or camouflaged to appear to be an integrated part of the utility pole.
3. Mounting Brackets: The antenna and mounting bracket shall:
a. Utilize the thinnest silhouette that technology allows;
b. Be constructed of nonreflective material.
4. Height: A WCF may exceed the height of the utility pole by no more than ten feet (10').
5. Pole Replacement: Existing utility poles may only be replaced with a new pole of the same height, dimension and appearance as the existing pole. (Ord. 2011-01, 1-18-2011; Ord. 2006-08, 6-29-2006; Ord. 2001-09, 10-1-2001; Ord. 2023-01, 1-3-2023)
