Subject to Subsection (D) below, telecommunication facilities are regulated in the following zoning districts:
[Ord. No. 13-060 §1, 8-12-2013]
1. 
"A" Agricultural District. Telecommunication facilities are allowed in the Agricultural District only with the issuance of a conditional use permit, provided that the distance from the center of the base of the tower to the nearest property line shall not be less than the height of the tower. The height of the proposed telecommunication facility shall be stated in the conditional use permit. The minimum distance between telecommunication towers shall be one (1) mile with the issuance of the conditional use permit.
2. 
"CO" Office District and "C1" Neighborhood Commercial District permit telecommunication facilities to a height of sixty (60) feet for one (1) user and to a height of eighty-five (85) feet for two (2) or more users, provided that the distance from the center of the tower base to the nearest "A" (Agricultural) or "R" (Residential) District property line shall not be less than the height of the tower. Any telecommunication facility[1] in excess of eighty-five (85) feet in height requires the approval of a conditional use permit. The minimum distance between telecommunication towers shall be one (1) mile.
[1]
Note—The word "facility" was not contained in the original ordinance and has been editorially added after conferring with the county.
3. 
"C2" General Commercial District permits telecommunication facilities to a height of one hundred (100) feet for one (1) user and to a height of one hundred twenty-five (125) feet for two (2) or more users, provided that the distance from the center of the tower base to the nearest "A" (Agricultural) or "R" (Residential) District property line shall not be less than the height of the tower. Any telecommunication facility in excess of one hundred twenty-five (125) feet in height requires the approval of a conditional use permit. The minimum distance between telecommunication towers shall be one (1) mile.
4. 
"I1" Light Industrial District and "I2" Heavy Industrial District permit telecommunication facilities to a height of one hundred fifty (150) feet for one (1) or two (2) users and to a height of one hundred seventy-five (175) feet for three (3) or more users, provided that the distance from the center of the tower base to the nearest "A" (Agricultural) or "R" (Residential) District property line shall not be less than the height of the tower. Any telecommunication facility in excess of one hundred seventy-five (175) feet requires the approval of a conditional use permit. The minimum distance between telecommunication towers shall be one (1) mile except where telecommunication tower farms are permitted.
5. 
Existing structures. Telecommunication antennas may be added to specific existing structures in any zoning district, provided the device does not extend greater than five (5) feet above the existing structure. Examples of these types of structures include water towers, broadcast towers, fire stations, church steeples, billboards, etc. Such telecommunication antennas shall be painted and/or textured to match the existing structure on which it is installed. A telecommunication antenna shall not be added or attached to a residence or a residential structure other than exemptions in this Section.
B. 
General Regulations Relating To Telecommunication Facilities.
1. 
Except as permitted by a conditional use permit in the "I1", Light Industrial District or "I2", Heavy Industrial District, only one (1) telecommunication tower shall be allowed on an individual property.
2. 
All towers shall be secured with fencing or anti-climbing devices.
3. 
Stealth telecommunications facilities (concealed towers) may be located in attics, steeples, towers, behind and below parapets or totally concealed within a new architectural addition to a building or a structure. On existing structures the antennas for telecommunication facilities with stealth design shall not extend more than five (5) feet beyond the edge of the attached structure and shall be painted and/or textured to match the existing structure on which it is installed.
4. 
No sign shall be allowed on the antennas, telecommunication facility, or equipment enclosures other than the telecommunication company's identification sign or warning signs not to exceed two (2) square feet in area.
5. 
The regulations concerning telecommunication towers shall prevail when there are conflicts between the height limits and the building setback standards of the respective zoning districts and these regulations.
6. 
Telecommunication towers, guy wires, shelter structures and other equipment, except for properties zoned "A" or "I", shall provide a minimum setback of twenty-five (25) feet in all directions from the property limits. Those properties zoned "I" must meet all setback requirements of the zoning district. In the "A" Agricultural District the minimum front, side and rear setbacks for the tower shall be equal to the height of the telecommunication facility. All other structures associated with the telecommunication facility in the "A", Agricultural District shall meet the minimum principal structure setbacks.
7. 
The design of the telecommunication facility shall maximize the use of building materials, colors, textures, screening and landscaping that effectively blend the facilities with the surrounding natural setting and environment.
8. 
No telecommunication tower shall be used for any other use other than as an antenna support structure, except when such other use is part of the applicant's efforts to camouflage the facility or have a stealth design.
9. 
(Reserved)[2]
[2]
Editor’s Note: Former Subsection B(9), which set forth requirements for design loads for telecommunications towers equal to or greater than 150 feet in height, was repealed by Ord. No. 13-060, §1, 8-12-2013.
10. 
The Planning and Zoning Division shall be notified within thirty (30) days when a telecommunication facility is no longer in use for communication purposes under County ordinance. All abandoned or unused telecommunication facilities shall be removed from the property within one hundred eighty (180) days of the ceasing of operations.
11. 
An existing telecommunication facility may be replaced with a new facility including for co-use under the existing facility’s already approved land use or conditional use permit, provided the existing facility is removed from the property. The new telecommunication facility shall not exceed the height of the facility being replaced. New facilities approved under this provision are not exempt from other requirements of this Unified Development Ordinance (such as requirements for site plan approval) or of the Building Code of St. Charles County.
[Ord. No. 13-060 §1, 8-12-2013]
12. 
Telecommunication farms shall have all towers of similar design and height. Said farm shall not contain more than three (3) towers per acre.
13. 
Exemptions: The following are considered exempt telecommunication facilities, and are not governed by this Section when erected as an accessory structure:
a. 
A single telecommunication antenna for the sole use of the tenant or owner occupying a residential parcel and used as accessory to the permitted use of such property. Such antenna shall conform to the height and setback requirements of the district they are located in.
b. 
A single telecommunication facility, which is accessory to the principal[3] non-residential use of the property. Such facilities shall conform to the height and setback requirements of the district they are located in.

Note—The word "principal" was changed from the word principle which was contained in the original ordinance editorially after conferring with the county.
