RE: USR 1072; Request for Additional Information for a Proposed Telecommunication
Facility near KEENESBURG, Colorado.
Dear Mr Schuett:
Due to the holidays, I was not able to compile the information you requested until now. I
apologize for any inconvenience this may have caused. Specifically, you requested
information regarding: 1) the area impacted by a tower failure and 2) a discussion about
collocation with other towers in the area.
With respect to tower failure, the attached letter from Andrew Corporation, Exhibit 1,
explains the design parameters and failure characteristics. In short, debris from a tower
;Talkie can be expected to fail Within a l adios of 6G% of the tow, height, i.e., approximately
98 feet. The current site plan does not allow for this distance to the south ROW line of WCR
18. In order to meet this requirement we will "flip" the layout such that tower is on the south
side of the leasehold. We will concur with this as a condition of approval and will show this
revision on the USR Site Plan prior to recordation. This will provide approximately 105 feet
of freefall to the ROW and 210 feet to the eastern property line.
There are two existing towers in the vicinity of OneComm's proposed facility. The taller
tower to the northwest is an FAA tower. The FAA will not allow other users on their towers
for security reasons and possible interference with their operations. The other tower located
directly north of the subject site is a cellular communications tower. This tower is
inappropriate for collocation because of possible radio frequency interference and because it is
too short (approximately 50 feet) to accommodate the coverage area intended by the subject
tower.

Dear Mr. Tomczac:
Andrew Corporation Ls writing on behalf of OneComm and their 150'
SCAT cellular communication tower proposed for construction at
Keenesburg, Colorado. The tower is proposed to be a tapered,
triangular cross-section, self supporting structure designed per
EIA 222-E with a basic wind speed of 85 mph with 1/2" radial ice
load.
Andrew Corporation designs, manufactures and installs
communication towers and the antenna systems that mount to them.
Over the past 25 years we have designed and installed over 3,000
guyed and self-supporting towers in all climates, worldwide.
(The towers were formerly marketed under the name of Grasis
Corporation before it was acquired by Andrew Corporation in July
of 1983.)
First, we would like to assure you that Andrew self-supporting
towers..are engineered and designed by professional engineers
using computer assistance and the same accepted codes and
standards as are typically used for high-rise building
construction. Our towers are designed in accordance with the
•
'Electronic Industries Association (EIA) Standard EIA/TIA-222-E
which has been accepted and approved by ANSI and is a nationally
recognized:tower design standard.
.The•ANSI/EIA Standard utilizes a "stepped" wind loading in tower
design. This means that a standardized wind speed (the "basic
wind speed") is applied to the tower structure at the 33 foot
level and then isI"increased" with increments of tower height,
Using the appropriate wind speed for each antenna level, the
thrust load of the antenna and its corresponding waveguide load
are applied to•the tower structure for maximum member loads.
The basic wind speed is determined from published wind maps.
These maps show lines of common wind velocity and thus can be
used to determine the annual extreme fastest -mile speed at 33
feet above ground level. The maps are based upon a 50 year
recurrence interval, which is 0.02 probability each year of these
950499
''ANDREW
basic wind speeds occurring. Many national codes including
ANSI/EIA, ASCE 7-88, and (BOCA or BBC) use the same or similar
probability maps.
As another loading condition, the ANSI/EIA/TIA 222-E recommends
that if the tower is located in an area where icing occurs the.
ice accumulation be included in the tower design along with a
wind loading likely to occur simultaneously. With the exception
of towers designed for Florida and the southern part of the Gulf
states, most of Andrew's tower designs include a minimum of 0.5
inches of radial ice on all tower members as one of its design
loading cases.
Naturally, no structure can be absolutely guaranteed to stand up
forever, since"it is impossible to anticipate freaks of nature,
accidents, or`•'acts of vandalism. Of the 600 plus self-supporting
'towers that we havermanufactured, we know of less than 1/2 of 1
percent that have experienced any kind of failure. These
failures have always been associated with loading far in excess
of the tower design loading. Thus, a failure due to a tornado is
a possibility; but the damage of failure would be no worse (and
probably less) than that sustained by adjacent structures.
When towers do Come down, one tends to envision them falling
straight over, intact, until they hit the ground. This is a
popular misconception. Self-supporting type towers rarely fail
at all, but when they do, the base usually stays intact while the
structure itself "bends" somewhere along its length, and "folds"
to the ground. This is because the structure is designed to
support itself while standing upright, and not while in a
horizontal position. As the tower starts to fall, it becomes
more horizontal; this induces secondary failures along the mast
and the tower ends up "folding" to the ground, if it makes it
that far. Sometimes the top sections will just bend over and
hang there. In any case, all the debris will most likely lie
within a circle whose center is the tower base and whose radius
is equal to no more than 60% of the tower height. This is well
within the one-to-one ration required for setbacks.
We hope the above information will prove helpful Nin reaching a
favorable decision regarding tower construA�•o

RE: Application for a Use by Special Review for a OneComm Corporation
Telecommunication Facility; Part of N/2, E/2, E/2 of Section 27, T 2 N, R 64 W;
KEENESBURG, Weld County, Colorado.
Dear Ms. Dunn:
Site Acquisition Services, Inc. ("SASI") represents OneComm Corporation ("OneComm"), a
wireless telecommunications company, for zoning and land use matters. Through SASI,
OneComm is submitting the included Use by Special Review Application and supporting
information to Weld County for its review and consideration.
ONECOMM CORPORATION
OneComm is one of the largest providers of Specialized Mobile Radio ("SMR") wireless
communications services in the United States, as measured by the population of its service
areas. OneComm is in the process of replacing the SMR system it owns and manages with
digital mobile networks. The new, Enhanced Specialized Mobile Radio ("ESMR") networks
use digital technology (referred to as the "Motorola Integrated Radio System" - "MIRS")
developed by Motorola, Inc. Through the application of digital technology and multi -site
reuse of frequencies, Digital Mobile Networks are expected to provide OneComm with ESMR
capacity of up to fifteen times its current SMR capacity. OneComm's digital,
telecommunications service capacity will be comparable to or higher than that of a single,
analog, "cellular" carrier in a similar geographic region.
OneComm activated its digital network to provide commercial service to the general public
along the Front Range of Colorado on June 30, 1994. The referenced, proposed facility will
provide ESMR services to the Keenesburg area and along the I-76 corridor.
OneComm's ESMR services include an enhanced form of traditional, analog based cellular
service, called digital cellular; digital two-way radio, with one-to-one and group
communications modes; message paging, with numeric or text capacity of 140 characters;
voice mail with on -screen notification of new messages; and, soon, wireless data transmission

without adding additional hardware. What is really new and truly unique is that all of the
listed features are provided by OneComm with a single easy -to -use handset, the OneComm
"Unicator."
GENERAL DESCRIPTION AND FACILITY OPERATIONAL CHARACTERISTICS
OneComm proposes to construct its facility, consisting of antennas, antenna support structure
and equipment building as shown on the Site Plan and Elevations, Exhibit 2. The site is
zoned Agricultural, and therefore, the development will require the approval a Use by Special
Review by the Board of County Commissioners. The site is not within any Overlay Districts.
OneComm has located the proposed facility on a site that offers a relatively unique
opportunity from which OneComm's wireless telecommunications services can be provided to
the intended service area, with a minimal number of facilities.
The properties to the east, south and west are primarily agricultural. Directly north is a
salvage yard. Approximately 900 feet north are two existing communication towers. The
nearest residential structures at the northeast quadrant of WCR 18 and WCR 57. The next
closest residential structures are approximately a quarter of a mile east and west along WCR
18.
The facility is not manned and once the facility is in normal operation there will typically
only be two or fewer maintenance trips, by passenger vehicle, to the facility per month. The
equipment building will be monitored by land -line telephone for any disruptions in service
that would occur due to equipment failure or accident. Since the facility is not manned there
is no need for water or sanitary sewer service. There are no adverse effects on health, safety
and welfare of the inhabitants of the county, and in fact, there will be a positive impact due
to the increase in access to mobile communications.
There will be no animals at the facility. There will not be any processing on the site. There
will not be any waste, stockpile, or storage areas associated with the proposed use.
Existing roads will be used to access the facility, except for a new driveway about 70 feet in
length. Any area disturbed during construction will be revegetated with native plant materials
and, as the related earthwork is small, there will be minimal opportunity for dust or soil
erosion. The proposed facility will not significantly increase the peak storm water runoff rate
above the existing condition since the impervious area will be increased only by the area of
the new building. The facility will require approximately two months to construct and
construction is planned to begin in the first quarter of 1995.
WELD COUNTY COMPREHENSIVE PLAN AND ZONING ORDINANCE
The Weld County Comprehensive Plan states that agriculture is the dominant industry in the
county and that the "Agricultural Goals and Policies have been developed to support and
preserve the agricultural industry." Indeed Agricultural Policies 3 and 4 discourage the
2
5)5O449
conversion of agricultural land to commercial development, when located outside of a
municipality's comprehensive plan area or urban growth area. Because of the nature of the
placement of the system's facilities, as discussed above, it is not possible to locate the facility
in a municipality. It is, however, located within the Keenesburg Urban Growth Area. There
are no adverse impacts on agricultural land, because the affected area is small (3500 s.f.).
