[12-8-1997 STM; amended 12-1-2003 STM, Art. 3]
A. 
Purpose and intent. It is the express purpose of this bylaw to minimize the visual and environmental impacts of personal wireless service facilities, consistent with the provisions of Sections 253 and 704 of the Federal Telecommunications Act of 1996. The bylaw enables the review and approval of personal wireless service facilities by the Town's Board of Appeals in keeping with existing bylaws and historic development patterns. It sets standards which are intended to preserve the safety, character, appearance, property values, natural resources and historic sites of the Town; mitigate any adverse visual effects through proper design, location and screening of structures; and to encourage co-location of antennas where feasible in order to minimize the total number of sites required.
B. 
Scope. This article shall apply to all wireless telecommunications antennas and towers and related equipment, fixtures and enclosures, including any modifications to any of the preceding, but shall not apply to fire, police, ambulance and other safety communications antennas, amateur (ham) radio or citizens band radio antennas, or to non-transmitting television antennas.
A. 
Use regulations. A personal wireless service facility shall require a building permit in all cases, and may be permitted as follows:
(1) 
A personal wireless service facility may locate on any existing guyed tower, lattice tower, monopole, electric utility transmission tower, fire tower or water tower, provided that the installation of the new facility does not increase the height of the existing structure except as provided in Subsection C(2) below. Such installations shall not require a special permit but shall require site plan approval by the Board of Appeals.
(2) 
A personal wireless service facility involving construction of one or more ground or building (roof or side) mounts shall require a special permit. Such facilities may locate by special permit in all zoning districts within the Town, provided that the proposed use complies with the height and setback requirements of Subsection C and all of the special permit regulations set forth in § 201-23.3 of this bylaw.
(3) 
A personal wireless service facility that exceeds the height restrictions of Subsection C(1) through (3) may be permitted by special permit in a designated Wireless Service Overlay District provided that the proposed facility complies with the height restrictions of Subsection C(4) and with all of the setback and special permit regulations set forth in Subsection C and § 201-23.3 of this bylaw.
B. 
Location. Applicants seeking approval for personal wireless service facilities shall comply with the following:
(1) 
If feasible, personal wireless service facilities shall be located on existing structures, including but not limited to buildings, water towers, existing telecommunications facilities, utility poles and towers and related facilities, provided that such installation preserves the character and integrity of those structures. In particular, applicants are urged to consider use of existing telephone and electric utility structures as sites for one or more personal wireless service facilities. The applicant shall have the burden of proving that there are no feasible existing structures upon which to locate.
(2) 
If the applicant demonstrates that it is not feasible to locate on an existing structure, personal wireless service facilities shall be designed so as to be camouflaged to the greatest extent possible, including but not limited to use of compatible building materials and colors, screening, landscaping and placement within trees to create an effective year-round visual buffer.
(3) 
The applicant shall submit documentation of the legal right to install and use the proposed facility at the time of application for a building and/or special permit.
C. 
Dimensional requirements. Personal wireless facilities shall comply with the following requirements:
(1) 
Height, general. The height of a personal wireless service facility shall not exceed by more than 10 feet the height limits of the zoning district in which the facility is proposed to be located, unless the facility is completely camouflaged or concealed such as within a steeple, chimney or similar structure. Personal wireless service facilities may locate on a building that is legally nonconforming with respect to height, provided that the facilities do not project above the existing building height.
(2) 
Height, existing structures. New antennas located on any of the following structures existing on the effective date of this bylaw shall be exempt from the height restrictions of this bylaw: water towers, guyed towers, lattice towers, fire towers and monopoles, provided that:
(a) 
Location on existing water towers will be subject to approval of the proposed attachment methods and maintenance procedures by the Water Department and Board of Health; and
(b) 
There is no increase in height of the existing structure as a result of the installation of a personal wireless service facility.
(3) 
Height, existing structure (utility). New antennas located on any of the following existing structures shall be exempt from the height restrictions of this bylaw provided that there is no more than a twenty-foot increase in the height of the existing structure as a result of the installation of a personal wireless service facility: electric transmission and distribution towers, telephone poles and similar existing utility structures. This exemption shall not apply in historic districts, within 150 feet of the right-of-way of any scenic roadway, or in designated scenic viewsheds.
(4) 
Height, Wireless Facility Overlay District. Within the Wireless Facility Overlay District (as designated on the Town Zoning Map), personal wireless service facilities of up to 150 feet are permitted by special permit. These taller structures shall be of non-guyed design and shall comply with all setback and special permit regulations as set forth in this bylaw.
(5) 
Setbacks.
(a) 
All personal wireless service facilities and their equipment shelters shall comply with the building setback provisions of the zoning district in which the facility is located. In addition, the following setbacks shall be observed:
[1] 
The minimum distance from the base of any ground-mounted personal wireless service facility to any property line, public way, or habitable dwelling shall be three times the height of the facility/mount, including any antennas or other appurtenances.
[2] 
In the event that an existing structure is proposed as a mount for a personal wireless service facility, the setback provisions of the underlying zoning district shall apply. In the case of preexisting nonconforming structures, personal wireless service facilities and their equipment shelters shall not increase any nonconformities, except as provided in Subsection C(5)(b) below.
(b) 
Flexibility. In reviewing a special permit application for a personal wireless service facility, the Board of Appeals may reduce the setback by as much as 2/3 of the required distance, if it finds that a substantially better design will result from such reduction. In making such a finding, the Board of Appeals shall consider both the visual and safety impacts of the proposed use.

In the event that co-location is found to be not feasible, a written statement of the reasons for the unfeasibility shall be submitted to the Town. The Town may retain a technical expert in the field of RF engineering to verify if co-location at the site is not feasible or is feasible given the design configuration most accommodating to co-location. The cost for such a technical expert will be at the expense of the applicant. The Town may deny a special permit to an applicant that has not demonstrated a good faith effort to provide for co-location.
C. 
If the applicant does not intend to co-locate or to permit co-location, the Town shall request drawings and studies which show the ultimate appearance and operation of the personal wireless service facility at full build-out.
D. 
If the Board of Appeals approves co-location for a personal wireless service facility site, the special permit shall indicate how many facilities of what type shall be permitted on that site. Facilities specified in the special permit approval shall require no further zoning approval. However, the addition of any facilities not specified in the approved special permit shall require a new special permit.
E. 
Estimates of RFR emissions will be required for all facilities, including proposed and future facilities.
A modification of a personal wireless service facility may be considered equivalent to an application for a new personal wireless service facility and require a special permit when the following events apply:

(1) 
Change in the number of facilities permitted on the site.
(2) 
Change in technology used for the personal wireless service facility.
(3) 
Additional equipment shelter.
B. 
The applicant and/or co-applicant wants to add any equipment or additional height not specified in the original design filing.
A. 
Within 90 days of the beginning of operations, and annually thereafter, the applicant shall submit measurements of RFR from the personal wireless service facility. Such measurements shall be signed and certified by a RF engineer, stating that RFR measurements are accurate and meet FCC guidelines as specified in § 201-23.3C(1).
B. 
The applicant and co-applicants shall maintain the personal wireless service facility in good condition. Such maintenance shall include, but shall not be limited to, painting, structural integrity of the mount and security barrier and maintenance of the buffer area and landscaping.
A. 
At such time that a licensed carrier plans to abandon or discontinue operation of a personal wireless service facility, such carrier will notify the Town by certified United States mail of the proposed date of abandonment or discontinuation of operations. Such notice shall be given no less than 30 days prior to abandonment or discontinuation of operations. In the event that a licensed carrier fails to give such notice, the personal wireless service facility shall be considered abandoned upon such discontinuation of operations.
B. 
Upon abandonment or discontinuation of use, the carrier shall physically remove the personal wireless service facility within 90 days from the date of abandonment or discontinuation of use. "Physically remove" shall include, but not be limited to:
(1) 
Removal of antennas, mounts and equipment shelters and security barriers from the subject property.
(2) 
Proper disposal of the waste materials from the site in accordance with local and state solid waste disposal regulations.
(3) 
Restoring the location of the personal wireless service facility to its natural condition, except that any landscaping and grading shall remain in the after-condition.
C. 
If a carrier fails to remove a personal wireless service facility in accordance with this section of this bylaw, the Town shall have the authority to enter the subject property and physically remove the facility. The Board of Appeals may require the applicant to post a bond at the time of construction to cover costs for the removal of the personal wireless facility in the event the Town must remove the facility.
Guyed towers, lattice towers, utility towers and monopoles in existence at the time of adoption of this bylaw may be reconstructed, altered, extended or replaced on the same site by special permit, provided that the Board of Appeals finds that such reconstruction, alteration, extension or replacement will not be substantially more detrimental to the neighborhood and/or the Town than the existing structure. In making such a determination, the Board of Appeals shall consider whether the proposed reconstruction, alteration, extension or replacement will create public benefits such as opportunities for co-location, improvements in public safety and/or reduction in visual and environmental impacts. No reconstruction, alteration, extension or replacement shall exceed the height of the existing facility by more than 20 feet.
A special permit issued for any personal wireless service facility over 50 feet in height shall be valid for 20 years. At the end of that time period, the personal wireless service facility shall be removed by the carrier or a new special permit shall be required.
