For the purpose of this chapter, certain terms and words are herewith
defined as follows:
ACCESSORY STRUCTURE
An accessory facility or structure serving or being used in conjunction
with a telecommunications facility or tower and located on the same lot as
the telecommunications facility or tower. Examples of such structures include
utility or transmission equipment, storage sheds or cabinets. The term "accessory
structures" does not include offices, long-term storage of vehicles or other
equipment storage, or broadcast studios.
ALTERNATIVE TOWER STRUCTURE
Man-made trees, clock towers, bell steeples, light poles and similar
alternative mounting structures that camouflage or conceal the presence of
antennas or towers.
ANTENNA
Any exterior apparatus designed for telephonic, radio, data, Internet
or television communications through the sending and/or receiving of electromagnetic
waves, and includes equipment attached to a tower or building for the purpose
of providing personal wireless services, including unlicensed wireless telecommunications
services, wireless telecommunications services utilizing frequencies authorized
by the Federal Communications Commission for "cellular," "enhanced specialized
mobile radio" and "personal communications services," telecommunications services,
and its attendant base station.
BACKHAUL NETWORK
The lines that connect a provider's towers/cell sites to one
or more cellular telephone switching offices, and/or long distance providers,
or the public switched telephone network.
COLLOCATED ANTENNAS
Personal wireless service facilities which utilize existing towers,
buildings or other structures for placement of antenna(s) and which do not
require construction of a new tower.
COW
"Cell on wheels," which is a temporary facility rolled in or installed
and used for a period of no longer than 90 days.
EIA
The Electronic Industries Association.
FAA
The Federal Aviation Administration.
FCC
The Federal Communications Commission.
HEIGHT
When referring to a tower or other structure, the distance measured
from the finished grade of the parcel to the highest point on the tower or
other structure, including the base pad and any antenna. If the support structure
is on a slope grade, then the average between the highest and lowest grades
shall be used in calculating the antenna height.
MOUNT
The structure or surface upon which personal wireless service facilities
are mounted. There are three types of mounts:
A.
BUILDING-MOUNTEDA personal wireless service facility mount fixed to the roof or side of a building.
B.
GROUND-MOUNTEDA personal wireless service facility mount fixed to the ground, such as a tower.
C.
STRUCTURE-MOUNTEDA personal wireless service facility fixed to a structure other than a building, such as light standards, utility poles and bridges.
PERSONAL WIRELESS SERVICE, PERSONAL WIRELESS SERVICE FACILITIES AND
FACILITIES
Shall be defined in the same manner as in Title 47, United States
Code, Section 332 (c)(7)(C), as they may be amended now or in the future,
and includes facilities for the transmission and reception of radio or microwave
signals used for communication, cellular phone, personal communications services,
enhanced specialized mobile radio and any other wireless services licensed
by the FCC and unlicensed wireless services.
PREEXISTING TOWERS AND PREEXISTING ANTENNAS
Any tower or antenna for which a building permit or special use permit
has been properly issued prior to the effective date of this chapter, including
permitted towers and antennas that have not yet been constructed so long as
such approval is current and not expired.
TOWER
Any structure that is designed and constructed primarily for the
purpose of supporting one or more antennas for telephone, radio and similar
communication purposes, including self-supporting lattice towers, guyed towers
or monopole towers. The term includes radio and television transmission towers,
microwave towers, common-carrier towers, cellular telephone towers, alternative
tower structures and the like. The term includes the structure and any support
thereto.
VIEWSHED
All the areas, from which an object (such as a tower) can be seen
by an observer, generally considered while standing at ground level. Areas
not visible due to intervening topography alone are considered NOT visible,
while areas generally without views due to intervening vegetation are considered
POTENTIAL viewshed. A viewshed is usually considered to extend to a distance
where the potential impact is lessened due to atmospheric conditions. For
the purpose of visual impact analysis of towers, a practical limit for viewshed
analysis is often three to five miles.
