For the purposes of this chapter, the following definitions apply:
"Antenna"means any structure or device used to collect or radiate electromagnetic waves for the provisions of services including, but not limited to, cellular, paging, personal communication services (PCS) and microwave communications.
"Base station"means a structure or equipment at a fixed location that enables FCClicensed or authorized wireless communications between user equipment and a communications network. The term does not encompass a tower as defined herein or any equipment associated with a tower. Base station includes, without limitation:
(a) Equipment associated with wireless communications services such as private, broadcast, and public safety services, as well as unlicensed wireless services and fixed wireless services such as microwave backhaul.
(b) Radio transceivers, antennas, coaxial or fiber-optic cable, regular and backup power supplies, and comparable equipment, regardless of technological configuration (including distributed antenna systems ("DAS") and small-cell networks).
(c) Any structure other than a tower that, at the time the relevant application is filed with the town of Twisp under this section, supports or houses equipment described in subsections
(a) and
(b) of this definition that has been reviewed and approved under the applicable siting process, or under another state or local regulatory review process, even if the structure was not built for the sole or primary purpose of providing that support.
The term does not include any structure that, at the time the relevant application is filed with the town of Twisp under this chapter, does not support or house equipment described in subsections (a) and (b) of this definition. |
"Collocation"means the mounting or installation of transmission equipment on an eligible support structure for the purpose of transmitting and/or receiving radio frequency signals for communications purposes.
"Eligible facilities request"means any request for modification of an existing tower or base station that does not substantially change the physical dimensions of such tower or base station, involving:
(a) Collocation of new transmission equipment;
(b) Removal of transmission equipment; or
(c) Replacement of transmission equipment.
"Eligible support structure"means any tower or base station as defined in this chapter; provided, that it is existing at the time the relevant application is filed with the town of Twisp under this chapter.
Existing.A constructed tower or base station is existing for purposes of this chapter if it has been reviewed and approved under the applicable siting process, or under another state or local regulatory review process; provided, that a tower or base station that has not been reviewed and approved when it was built, but was lawfully constructed, is existing for purposes of this chapter.
"Monopole"means a single, freestanding pole-type structure supporting one or more antenna. For the purposes of this chapter, a monopole is not a tower.
"Site"means for towers, other than towers in the public rights-of-way, the current boundaries of the leased or owned property surrounding the tower and any access or utility easements currently related to the site, and, for other eligible support structures, further restricted to that area in proximity to the structure and to other transmission equipment already deployed on the ground.
Substantial Change.A modification substantially changes the physical dimensions of an eligible support structure if it meets any of the following criteria:
(a) For towers other than towers in the public rights-of-way, it increases the height of the tower by more than 10 percent or by the height of one additional antenna array with separation from the nearest existing antenna not to exceed 20 feet, whichever is greater; for other eligible support structures, it increases the height of the structure by more than 10 percent or more than 10 feet, whichever is greater;
(b) For towers other than towers in the public rights-of-way, it involves adding an appurtenance to the body of the tower that would protrude from the edge of the tower more than 20 feet, or more than the width of the tower structure at the level of the appurtenance, whichever is greater; for other eligible support structures, it involves adding an appurtenance to the body of the structure that would protrude from the edge of the structure by more than six feet;
(c) For any eligible support structure, it involves installation of more than the standard number of new equipment cabinets for the technology involved; or, for towers in the public rights-of-way and base stations, it involves installation of any new equipment cabinets on the ground if there are no preexisting ground cabinets associated with the structure, or else involves installation of ground cabinets that are more than 10 percent larger in height or overall volume than any other ground cabinets associated with the structure;
(d) It entails any excavation or deployment outside the current site;
(e) It would defeat the concealment elements of the eligible support structure; or
(f) It does not comply with conditions associated with the siting approval of the construction or modification of the eligible support structure or base station equipment; provided, however, that this limitation does not apply to any modification that is noncompliant only in a manner that would not exceed the thresholds identified in subsections
(a) through
(d) of this definition.
"Tower"means any structure built for the sole or primary purpose of supporting any FCC-licensed or authorized antennas and their associated facilities, including structures that are constructed for wireless communications services including, but not limited to, private, broadcast, and public safety services, as well as unlicensed wireless services and fixed wireless services such as microwave backhaul, and the associated site.
"Transmission equipment"means equipment that facilitates transmission for any FCC-licensed or authorized wireless communications service, including, but not limited to, radio transceivers, antennas, coaxial or fiber-optic cable, and regular and backup power supply. The term includes equipment associated with wireless communications services, including, but not limited to, private, broadcast and public safety services, as well as unlicensed wireless services and fixed wireless services such as microwave backhaul.
"Wireless communications facilities (WCF)"means any structure or device used to collect or radiate electromagnetic waves for the provisions of services including, but not limited to, cellular, paging, personal communication services (PCS) and microwave communications. Such structures and devices include, but are not limited to, directional antennas such as panels, microwave dishes and satellite dishes, and omnidirectional antennas, such as whips. This definition does not apply to broadcast antennas, antennas designed for amateur radio use or satellite dishes designed for residential or household purposes.
