Finance and Administration
Project Summary (100 words or less) :Weld County operates a centralized communications
center serving most of the law enforcement, fire, emergency medical and general govern-
ment agencies in the county. This project would finance expansion and update of the
county system. The request is for Phase II of the project. The system is old and in
need of replacement and the system capacity is being reached as traffic volumes continue
to grow. A study conducted in 1984 by a radio engineering firm has determined the
radio communication system needs in Weld County, on the basis of activity. The study
did an analysis of the alternative ways in which the radio system might be changed on
the basis of performance compared to needs and cost. (Exhibit A) Phase I was funded
in 1985 with energy impact funds.

List major energy/mineral development projects affecting the applicant. Cite -
work force numbers and projections. Cite the number of energy and mineral
production employees residing within the jurisdiction. Cite how the proposed
project will mitigate any adverse impacts related to energy and mineral develop-
ment. List proposed projects which have the potential to affect the community.
List recent project closures or reduction in production/employment which affect
the jurisdiction:
The most significant projects affecting Weld County to date are related to oil & gas
production. The impacts are felt throughout the region as a whole, however, and are
not found exclusively in a community or neighborhood condition. Weld County currently
has approximately 3,205 active wells with oil & gas exploration continuing in Weld
County. According to the Petroleum Information Corp. , oil & natural gas explorers
drilled & completed 590 wells in Weld County in 1984, a 44.3% increase from 1983. The
big jump made Weld County the 9th most active county in the nation in oil & gas comple-
tions. Weld's energy activity is attributed to continued interest in the high quality
condensate and gas-bearing Codell sandstone in the Denver-Julesburg Basin.
Weld County has over 200 oil & gas producers per the assessment rolls. Although
there is no available data providing the exact number of employees when all support
functions (e.g. , engineering, drilling, fracing, fluid disposal, maintenance, etc.)
are considered, there are several hundred employees in Weld County associated with the
oil industry.
Weld County's population has grown from 89,297 in 1970 to 131,464 in 1985.
If the project is a construction project, attach a map to the application
indicating the construction site. How was the project budget estimate
developed? How will the applicant deal with potential overruns? Have pre-
liminary architectural/engineering studies been wupleted?. Have project
architects/engineers been selected? If so, list the firm. If multiple sources
of funding are involved, are any of the funds limited to a particular portion
of the project budget? Are all revenues firmly committed or projected?
Provide any additional narrative information not included in the project
summary:
Not applicable
Why can't the project be funded locally? What alternatives to Impact
Assistance funding have been explored?
Local agencies will provide personnel to staff the Communication center and over 50%
matching share, but do not have the resources to acquire all the necessary equipment
to update communications system. Local agencies will replace their own radios.
This program services every municipality and fire district in Weld County. The
system provided critical communications services to every citizen in the county.
(CONTINUED ON ATTACHED PACE) 2
WHY CAN'T THE PROJECT BE FUNDED LOCALLY? (CONTINUED)
The fiscal responsibility is shared by all users ranging from Weld County to Fire
Districts with under $20,000/year budgets and towns (28) like
Property Tax
Grover 3,000
Severance 3,200
Commitments to replace radios are significant when one looks at the percentage
of budget a radio equals in relationship to the total budget. All 71 local agencies
will be making a commitment of funds to replace their own obsolete radios which will
amount to over $250,000 over the next five years. Weld County will be making a
commitment of $300,800 for the project.
Weld County has pursued a number of alternatives for financing the project.
Federal Funds: With LEAA no longer in existence the only federal or state source
is through FEMA. FEMA funds are not currently available to equip a mobile
communications center and emergency operations center as a backup to the system.
Lease/Purchase: Is not a practical solution when one looks at phasing in the
upgrade and having a long range commitment of over $100,000/year sustained
probably forever to keep the system cu-rent and cope with growth.
Reserve/Replacement: A long term effort of $100,000+/year will allow the system
to be replaced in the future. No reserve was provided for the current system
which has experienced technological obsolescence and growth pressures.
User Fees: Local agencies have the responsibility to acquire their radios and
maintain them. Weld County acquires and maintains the main system and staffs
the Communications Center at a cost of over $791,132 in 1986. Originally, a
1/2 mill was levied to support the system, today the cost exceeds 1 mill. User
fees have been discussed, but users have not been assessed other than agencies
having responsibility for radios and maintenance.
.�
Did the applicant/sponsor jurisdiction take the full 107% property tax revenue
increase this current budget year?
n/a. Weld County is a home rule county, limited to a 5% increase annually. Weld
County has taken the 5% each year since the Charter was enacted in 1976.
List major capital construction projects being undertaken and/or planned for
the current year, and the next two fiscal years:

Water Find $ n/a Sewer $ n/a
What was the end-of-year surplus (or deficit) for the
•
previous budget year? $ 282,367
If project is funded, what ongoing operational obligations will be incurred?
What is the applicant's plan for addressing these additional costs?
Weld County will continue to provide for the annual operations costs (1986 - $591,132)
for the Countywide Communications Center. Each user agency will continue to
provide for the maintenance of their own radios and replacement of their radios.
Identify any service or facility plan wherein this project has been identified
as a oonmunity need. If project is not funded with Impact Assistance funds,
what actions will the applicant take to accomplish the project?
See attached engineering report. If Impact Assistance funds are not received,
the project implementation will be delayed 2 - 3 years.

INTRODUCTION
A. PROJECT OVERVIEW
Weld County operates a centralized communications center
serving most of the law enforcement, fire, emergency
medical services and general government agencies that
operate in the county. A total of 71 agencies are
served. Only the Colorado Highway patrol, the City of
Greeley and the City of Fort Lupton provide their own
communications centers. The Sheriff provides information
service by voice radio to law enforcement officers
through a communications console located in the Sheriff ' s
offices. Weld County Department of Public Works
personnel can communicate directly with personnel in the
field.
The User agencies own and maintain their mobile and
portable radio equipment. At present, there are
approximately 227 mobile radios, 195 portable radios and
500 radio page receivers on the system. About 2/3 of the
mobile and portable radios are at or near the end of
their useful life. The number of radios and the volume
of radio traffic are growing steadily.
Three communications radio control consoles are available
in addition to the console in the Sheriff ' s offices.
These consoles can provide excellent service for at least
five more years.
The system was designed about ten years ago and has
generally provided good service during its life. Now,
however, the system is old and in need of replacement and
the system capacity is being reached as traffic volumes
continue to grow.
-1-
Other problems including interference from other radio
networks are serious . Corrective action to relieve the
effects of the problems is required. County personnel
recognize that technology has changed since the present
system was designed. It is possible that all of the
problems might be corrected through use of those new
technologies rather than by trying to fix each problem on
an individual basis .
The objective of this project is to provide the
information that Weld County personnel need to establish
the best direction to proceed to change and/or enhance
the radio communications system so as to provide relief
from the problems that exist.
B. ABOUT THIS REPORT
The remainder of this report consists of three sections.
One of those sections describes radio communications
systems needs in Weld County projects, on the basis of
activity, to the 1995 time period. 1995 was selected as
that is a reasonable time frame for the useful life of
any new system implemented over the next several years.
An analysis of the performance of the present system
compared to these projected needs is also included in
that section.
Another report section contains an analysis of
alternative ways in which the radio system might be
changed. These alternatives are evaluated on the basis
of performance compared to needs and on cost.
A separate section of the report is a discussion of
changes that are likely to be necessary to the
communications center.
-2-
The final section of the report contains •a set of
implementation steps that can be scheduled for
accomplishment over a period of several years to comply
with funding availability.

SECTION II
RADIO SYSTEM NEEDS
A. RADIO CHANNELS NEEDED
1. Law Enforcement
The number of law enforcement events handled by Weld
County Communications Center personnel doubled over
an eight year period between 1975 and 1982.
Population growth projections are an indication that
law enforcement activity and corresponding radio
traffic will increase by the same amount over the
next eight years. At this rate of growth, 100 , 000
law enforcement events including routine activities
will be handled in 1995 . In our past work, we have
found that a good estimate of activity volume during
busiest hours is 10% of the volume for an average
day. The 1995 average day volume is 274 events
(100 ,000 events per year divided by 365 days ) and
busiest hours volume will probably be about 27
events.
A LEAA funded study contains a methodology for
determining how many dispatchers are required to
handle a specific event volume during the busiest
hour (1 ) . Use of that methodology shows that in
1995, two dispatchers will be 55% fully loaded
handling law enforcement radio dispatching only
without performing answers to information inquiries
and without answering incoming telephone requests
for service. Each of those dispatchers requires a
(1) Multi-Community Command and Control Systems in Law
Enforcement, National Criminal Justice Information and
Statistics Service, September, 1978 .
-4-
separate dispatch radio channel because of the
volume of activity for each. Because of the volume
of traffic on the dispatch channels, a separate
radio channel will be needed for information
inquiries and that channel will be heavily used
during the busiest hours.
Law enforcement officers are often engaged in
activities requiring unit to unit tactical
communications without involvement of the dispatch
center. Examples are traffic control and parades or
community festivals. This radio traffic should be
kept separated from dispatch traffic and information
inquiries as traffic on channels used for those
purposes will be heavy and the addition of the
tactical traffic will lead to overloading.
Therefore, four radio channels for law enforcement
communications are required (two for dispatch, one
for information inquiries and one for tactical
activities ) . Weld County currently has only three
channels available.
2. Fire Service
Fire service radio communications can be divided
into two types - dispatch and fire scene tactical
operations.
Fire service radio dispatch includes alerting fire
fighters to respond to a fire event and
communications support to fire personnel on the
scene who may need additional support and/or
equipment.
Fire scene tactical operations involves direction of
personnel in and around structures for efficient
fire fighting and for increased personnel safety.
-5-
Weld County fire personnel have strongly indicated a
need for two dispatch channels and one tactical
channel. The tactical channel is important as it
means that all traffic at the fire scene is related
only to the fire event rather than mixed in with
dispatch traffic.
The two dispatch channels will be split between the
Northern and Southern parts of the county so that
only firefighter personnel in the appropriate part
of the county hear dispatchers in their or in nearby
areas.
There are presently only two channels in use in Weld
County but one of them 154 , 295 MHz must be abandoned
in 1986. Therefore, two more fire frequencies are
needed in the county.
3. Emergency Medical Services
The statewide plan for use of Emergency Medical
Services (EMS) frequencies in Colorado shows the
assignment of one uhf radio channel in Weld County.
The communications center is equipped to communicate
on that channel and should continue to operate there
so as to be able to communicate with ambulance
personnel from Weld County and other areas who enter
the county.
Weld County ambulance services are also licensed to
operate on a vhf frequency. The communications
center needs to be equipped to operate on this
frequency as well so that paging and other
activities can be performed. The communications
center is not able to use this frequency at present.
-6-
r r
Ambulances operating in Weld County will need to be
equipped with uhf and vhf radios to utilize these
two channels. This dual radio capability will
provide a simple and effective way for ambulance
personnel to directly coordinate with all fire, law
enforcement and governmental personnel without
crossband repeating radio channels. Coordination is
more fully discussed in a later section of this
report.
We believe that ambulance use of a uhf and vhf
channel in Weld County is an effective concept.
This double channel system will be adequate for EMS
use for the expected useful life of any new radio
system in Weld County.
4 . General Government
Many non-public safety government agencies in Weld
County are served over two uhf channels. The Road
and Bridge Department uses one and various
governmental transportation services are the primary
users of the other.
There are two other general government radio
channels in use. One is a uhf channel used by the
Road and Bridge Department only in the Eastern part
of Weld County around and East of the Town of
Grover. The other is a low band vhf channel used
for general one way radio paging and for two way
radio communications by a collection of Weld County
departments including Building Inspection, Health
Department and Building and Grounds Security.
-7-
Use of the low band radio channel requires a
different radio than that required to communicate on
a uhf channel. If the low band channel were
replaced by a uhf channel, all users could use a
common radio type, all could receive better channel
utilization through shared use of multiple channels
and all users could better coordinate activities
during extraordinary circumstances. In addition,
uhf is free of the serious skip interference that
plagues low band vhf. Low band vhf portable radios
are more difficult to use than uhf radios.
The radio site East of Grover is needed to provide
communications in the Eastern part of Weld County.
A single general government radio station located
there can be used by all governmental agencies if
all agencies use uhf radio equipment exclusively.
We believe that Weld County should try to obtain a
uhf channel and use it in place of an abandoned low
band vhf channel.
The uhf site in the Eastern part of the County is
lightly used while the main Road and Bridge channel
is already used at a near saturation point and
traffic volume is increasing steadily. The radio
channel used in the Eastern part of the county can
be reused, especially in the Southern part of the
county, by .using CTCSS tones.
The addition of one uhf channel as a replacement for
the low band channel and the reuse of the Grover
frequencies will provide four channels rather than
the present three in the Weld County area West of
Grover. The extra channel along with better channel
utilization should provide an effective increase in
channel traffic carrying capacity of more than 50%.
-8-
r- r.
Better utilization is possible because all agencies
would share the same group of channels and the two
channels used by the transportation agencies and by
the agencies on the low band channels are presently
lightly loaded.
B. RADIO COVERAGE
It is essential for personnel safety and for providing
adequate service that personnel in the field be able to
communicate with communication center personnel. No
radio system can make communications possible over 100%
of any area or, from some points, 100% of the time.
This is especially true in Weld County because of the
large county area and because of the terrain in the
Northern and Eastern parts of the county as radio
propagation is essentially line of sight in the available
frequency bands. The amount of area covered can be
increased by adding more fixed location radio sites , but
this is costly. Often the addition of another site can
add a large percentageincrement to the total system cost
while adding coverage to a small area so that percentage
of total area covered increases only a small amount.
It is often possible to achieve coverage 90% of the time
over 98% of an area like Weld County except for isolated
areas no larger than 2 miles across from a relatively
small number of fixed location radio sites. That will
provide a good grade of coverage for field personnel
especially if mobile and portable radios also have the
ability to provide communications on a direct radio to
radio basis.
-9-
Maps 1 through 4 at the back of this report show
mathematically predicted coverage presently available
from uhf radios to fixed location radio sites. These
maps do not show numerous small areas where signal levels
will be unacceptable. Vhf radio coverage will be
approximately the same as uhf as coverage is primarily
determined by terrain factors. Portable to fixed
location radio coverage will be much poorer than the map
coverages for mobile radios. Portable coverage is :
- The East central part of the county only from
the mountaintop sites.
- Approximately 2/3 of the area shown for mobiles
around the Grover site on Map 2.
- Approximately 1/2 of the area shown for mobiles
around the Empire site on Map 3.
These mathematically predicted coverages were confirmed
with users experience on September 11, 1984 .
The present mobile to base coverage in Weld County covers
about 75% of the county. The portable to base coverage
is about 20% of the county.
C. BACKUP COVERAGE
Radio communication is not possible if the fixed location
radio site is not fully operational. Fixed location
radio sites can be placed out of service by lightning,
high winds that cause towers or antenna failure or radio
failure. Often, loss of a site happens when the radio
system is needed most, for example, during a storm. To
prevent system outage, alternate fixed location sites
should be included from which coverage can be provided
when a primary site is out of service. A full
duplication can double the cost of the fixed location
-10-
radios. Therefore, partial duplication along with a
mobile van is a cost effective way to provide back up
coverage. A single back up radio site in Weld County may
provide coverage over 90% of the area from which 80% of
the radio traffic is generated.
At present, there is no back up for the Eastern part of
the county covered from the Grover site (Map 2 ) . There
is no back up for the fire service or EMS radio systems
as all fixed location radio equipment for these systems
operates at the Empire tower site only.
D. INTERFERENCE
An intermodulation analysis indicates that only minimal
interference from this source is possibly affecting Weld
County radio systems. The transmitter mixed
intermodulation caused interference can easily be handled
with appropriate and inexpensive filtering.
The primary interference sources are cochannel users and
the Littleton police department is a primary problem.
This interference can be eliminated through use of tone
coded squelch in receivers.
E. COORDINATION
There is an important need for personnel from different
public safety agencies to be able to communicate directly
with each other for safety and for carry out activities
in an effective and efficient manner. This need is
particularly evident at times of larger events such as a
tornado. The need is also present at events that happen
daily or almost every day when fire, EMS and law
enforcement personnel all respond to an event such as a
serious auto accident with injuries and fire.
-11-
At present, EMS personnel can communicate with fire
personnel, with law enforcement personnel and with other
government personnel. EMS personnel are not able to
patch the other public safety personnel together into a
single coordination network. None of the other services
can communicate directly with each other unless
communications center personnel set up a cross channel
patching arrangement. Cross channel patching is an
unusable method for coordination as all radio traffic on
all channels is repeated on all channels through the
patch. During normal hours, that is just too much
traffic for the patch and radio traffic during
significant public safety events is higher than normal.
In addition to the problem of trying to carry very heavy
traffic, all users must turn attention to their radios at
all times during a cross channel patch while sorting out
unimportant traffic in order to hear traffic that is
related to the event.
F. FIXED LOCATION RADIO STATION CONTROL
Fixed location radios need to be remotely control by
communications center personnel. Things that need to be
controlled include:
- Turn station on or off. This is absolutely
necessary when back up stations are available as two
fixed location stations on the same frequency and
covering the same area can not be on at the same
time or transmissions will not be intelligible.
- Disable and enable the repeat function. There are
times when the repeat function of a mobile relay
station must be disabled such as when a mobile radio
microphone keying switch is stuck on.
- Disable and enable tone coded squelch.
- Fixed location simplex radio stations for the fire
service can not be located at a remote site without
a control link.
-12-
Except for the stations at the Empire tower site, no
control of fixed location radio stations is presently
possible from the Weld County communications center.
-13-
SECTION III
RADIO SYSTEM CHANGE ALTERNATIVES
A. RADIO CHANNELS
In Section II.A. of this report, there is a discussion of
radio channel needs. Two high band vhf fire service
channels, one law enforcement uhf channel and one uhf
local government channel, in addition to the presently
licensed channels, are .needed if Weld County is to
continue using the present frequency bands. Lists of
radio frequency license holders in the Weld County have
been reviewed and it appears that two fire channels and
two 453/458 MHz uhf channels may be available for use in
Weld County if the City of Aurora begins the planned use
of the 800 MHz radio frequency band.
An alternative to continuing to operate in the presently
used bands is to change to use of radio frequencies in
the 800 MHz band. Sufficient radio frequencies are
available in that band and all other radio system needs
outlined in Section II can be met at 800 MHz.
800 MHz radios will be more expensive than vhf and uhf
radios especially since competitive bids may be difficult
to obtain for 800 MHz equipment after one vendor' s system
approach is adapted during the initial equipment
procurement. The additional mobile and portable radio
cost for an 800 MHz radio compared to a uhf or vhf radio
is about $500 each. Within the next three years, about
275 mobile and portable radios will need replacing by
Weld County and by user agencies as that many radios are
at or near the end of their useful life. Replacing
those radios with 800 MHz radios along with the
concurrent replacement of fixed location radios and
antennas will cost about $175,000 more than replacing old
radios with new vhf and uhf radios.
-14-
In addition, there are presently about 150 radios in use
that are from four to nine years away from the end of
their useful life. If the move to 800 MHz can be staged,
these radios may continue to be used to the end of their
useful life. If staging is not feasible, these radios
will need to be replaced now at an estimated cost of
$300 ,000. Remaining at vhf and uhf means that replacing
these radios can be put off for four to nine years and
the replacement cost will then be about $225 ,000 in 1984
dollars.
Remaining in the present radio bands also means that
ambulance, law enforcement and fire radios can have the
direct ability to communicate with radios used by
agencies outside Weld County on State of Colorado
designated coordination channels. A move to 800 MHz will
mean that more expensive, cumbersome and less reliable
cross band patching or use of two mobile and portable
radios will be necessary so that Weld County personnel
can use those valuable state designated coordination
resources.
If at all -possible, Weld County should continue to use
the presently used radio frequency bands with the
addition of four channels.
B. RADIO COVERAGE
1. Enhancement of Present Radio System
Radio coverage for law enforcement agencies and the
Road and Bridge Department is shown on Map 4 . This
coverage could be improved to reach the 98% of area
except for areas less than two miles across goal by
adding two fixed location sites. One of those sites
should be located beside CO 71 about five miles
South of the North county boundary on a short
(approximately 50 foot high) tower.
-15-
The second site should be a few miles North of the
Adams County line on one of several sites at about
5165 'msl. This site should use a tower about 200
feet high. Radio frequencies used at these sites
can be frequencies used elsewhere in the county but
with different CTCSS tone frequencies.
Radio coverage for the transportation services is
shown on Map 1. This coverage can be enhanced if
the transportation services would use the Road and
Bridge channels at the Grover, CO 71 and new South
sites.
Radio coverage for the fire and EMS and other Weld
County government agencies is shown on Map 3. This
coverage can be improved by moving the fixed
location radio stations at Empire to one of the
mountain top sites and adding stations at the
Grover, CO 71 and the new South sites.
The cost for implementation of these enhancements is
estimated and shown in the table on the top of the
next page.
Selection of this alternative will result in
recurring costs for a total of 13 fixed location
radio stations, four law enforcement, two fire, two
EMS and four general government radio stations on
the mountain. Current charges for use of the
mountain sites is $72.22, $126. 38 and $147 . 22 per
radio station per month depending on site and radio
type. These rates are subject to increase at
contract renewal times each year on January 1.
-16-
Tower near CO 71 including land, $ 40 ,000
shelter, power, access road and
four radio stations.
Tower in South including land, 71,000
shelter, power, access road and
five radio stations.
Modifications to 150 mobile radios 25 , 000
for multiple CTCSS tones.
Moving radio stations from Empire 10 , 000
to mountaintop
Five additional stations on mountains 30 , 000
Two additional stations at Grover 12 , 000
Total Initial Cost $188 , 000
2 . Revised System Alternative
An alternative to enhancement of the present system
is to abandon the two mountaintop sites and to build
two sites in Weld County. One site would be East or
Northeast of the Milton Reservoir with a 400 foot
tower at ground elevation. near 4850 'msl. This site
should be located in compliance with the latest
issues of AC 70/7460 published by the U.S.
Department of Transportation, Federal Aviation
Administration and Part 77 of the Federal Aviation
Regulations if the tower site is within four miles
of any airport runway.
A second site is required near US 85 near the
Wyoming border. The Grover site will continue in
use and the site beside CO 71 previously described
will also be needed.
-17-
Following is the estimated cost for implementing
this alternative.
Tower near CO 71 including land, $ 40 , 000
shelter, power, access road and
four radio stations.
Tower near Milton Reservoir 131, 000
including land, shelter, power
access road amd •five radio stations.
Modifications to 150 mobile radios 25, 000
for multiple CTCSS tones.
Moving eight radio stations 16 , 000
from Empire and mountains.
Two additional stations at Grover. 12, 000
Tower near US 85 in North 70 , 000
including land, shelter, power, •
access road, and nine radio stations.
Total Initial Cost $294 ,000
3. Variations on Alternatives
The basic alternatives described can vary somewhat.
The cost estimates assume that the present fixed
location radio stations will be retained and moved,
however new radios may be purchased at an increased
cost. The cost estimates also assume that separate
fixed location radio stations will be installed at
all sites for each service. However, at remote
sites, especially the one beside CO 71, only one
453/458 MHz station or one of those and one vhf fire
service channel might be installed instead to reduce
cost.
-18-
4. Portable Radio Coverage
The predicted radio coverages shown on Maps 1
through 4 at the back of this report are calculated
for the mobile to fixed location radio path. The
fixed location to mobile path will be about the same.
Hand held or portable radios have substantially
poorer reception capabilities than mobile radios
because of the antennas used and because portable
radios are often used inside vehicles or buildings.
In Weld County, the signal level along much of the
boundary lines of the good coverage area is above
the minimum required, and the good coverage area
would be greater except for the ground contour. As
a result, radio coverage from fixed location radio
stations to portable radio receivers will be about
the same as for mobile radios.
Portable radio transmitters operate at very low
power compared to mobile and fixed location radios
so that portable radio batteries can be kept small
in size and light in weight. Therefore, the area
over which portable radios can be used is small
compared to mobile radios because the portable radio
transmit power is so low.
The ability for law enforcement officers to
communicate with the communications center with a
portable radio is a critical safety consideration as
officers often need to call for assistance when they
are alone and away from the vehicle.
Portable radio to communication center
communications for other governmental employees may
not be as critically significant but is very
important.
-19-
Fire fighter personnel at a fire scene can use their
portable radio to talk to a fire fighter at a rig
who can then relay a message to the communications
center if the fire fighter with the portable radio
can not communicate directly. EMS personnel are
usually near their ambulance and there are at least
two persons at an event so that one can go to the
ambulance and use the mobile radio to reach the
communications center if communications with the
portable radio is not possible. Road and Bridge
personnel can usually walk to a vehicle to use a
mobile radio if the portable is out of range
although this may be inconvenient and inefficient.
One of the present problems with portable radio
communications is that the talk path is by repeater
action through the fixed location radio station and
not directly between the mobile and/or portable
radios. This means that all mobile and portable
radios used by personnel who wish to
intercommunicate must be able to reach the fixed
location radio station. All too often, persons who
can see each other can not communicate with each
other by radio because one or both can not
communicate with the fixed location radio station.
This problem can be overcome by use of a repeater
talk around feature in the mobile and portable
radios. We recommend inclusion of this feature in
all mobile and portable radios purchased in the
future except those used only on simplex radio
channels.
There are two ways to dramatically improve the
portable radio to communications center
communications. One will provide better performance
in some locations while the other will be better in
other locations. Neither has a clear coverage
advantage over the other.
-20-
"^.
One way to obtain improvement is through use of
vehicular repeaters. The Weld County Sheriff' s
office is using some of those now. The other way is
to add fixed location receiver sites in Weld County
so that low power portable transmitters have a
shorter distance, better path to a fixed location
receiver.
Each vehicular repeater costs approximately $1,200
(not including the associated portable radio) .
There are presently 71 law enforcement mobile radios
and 227 total mobile radios in use in Weld County.
Each satellite receiver will cost about $4 ,500
including antenna, installation and a comparator
module at the communications center and no more than
$12,000 for a communications link between the
receiver site and the communications center. An
antenna support structure must be provided at each
satellite receiver site and some existing structure
such as a city water tower should be used wherever
possible. Between four and eight satellite receiver
sites would likely provide the desired coverage
improvements. A satellite receiver system with five
sites on a single radio channel might cost $75,000
if no new radio antenna support tower with
associated building, power, land and/or access road
is needed.
The satellite receiver alternative has some
advantages over the vehicular repeater system.
- The vehicular repeater is less reliable due to
the complexity of the system and the amount of
radio equipment needed.
-21-
- There are operational problems in that only one
vehicular repeater can be enabled in the range
of multiple portable radios. Law enforcement
officers have no way of knowing when another
officer has enabled an in-range vehicular
repeater, even miles away, when they leave
their vehicle.
- The portable radios used with vehicular
repeaters can not be equipped with the talk
around capability allowing direct
mobile/portable .radio to radio communications.
- Mobile radio coverage is also improved with a
satellite receiver system.
C. BACK UP COVERAGE
Coverage from the Empire Tower (Map 3 at the back of this
report) includes the Weld County area in which more than
80% of public safety activity happens. No primary fixed
location radio stations would be located at Empire in
either system arrangement alternative described in
Subsections III.B.1. and 2. of this report. The Empire
Tower site is a good back up location for fixed location
radios. This site might be equipped with two law
enforcement, one fire, one EMS and one general government
radio stations rather than one for every channel in order
to save cost.
Weld County should also consider equipping a van with
appropriate radio equipment that could be used both as a
temporary back up fixed location radio facility and as a
field command post. This van should have an electric
generator for power and a radio complement determined by
the uses planned for the van.
-22-
D. INTERFERENCE
All radio equipment in use should always operate with
tone coded squelch to eliminate most or all of the
cochannel and adjacent channel and some intermodulation
interference.
Intermodulation interference caused by transmitter mixing
at fixed location radio sites should be determined
mathematically and reduced to an acceptable level through
use of isolators.
E. COORDINATION
Coordination between fire and law enforcement personnel
can be provided efficiently when required by the
establishment of a cross channel patch between the fire
and law enforcement tactical channels.
EMS personnel can coordinate directly with fire or law
enforcement personnel by selecting the proper channel on
one of two radios. EMS personnel can coordinate through
a cross channel patch by selecting either the fire or law
enforcement tactical channel on one of their radios.
F. RADIO STATION CONTROL
Control of remotely located radio stations can be
accomplished over telephone company provided lines or
over point to point radio links.
Each radio station requires a four wire, full duplex,
none signalling circuit. Telephone company line tariffs
for that kind of circuit are approximately $20 . 00 plus
$7 .00 per mile per month. Mileage is measured on a
direct point to point basis even through the actual
circuit may be routed differently.
-23-
A major site Northeast of the Milton Reservoir is about
12 miles from the communications center. Telephone
circuits for 13 stations at that site will cost
approximately $16 ,000 per year. A microwave radio link
can be installed for approximately $40 ,000 + $2 , 000 per
circuit if land, equipment shelter and a tower are
already available. For 13 circuits, a microwave line to
a site Northeast of the Milton Reservoir will cost
approximately $66 , 000 and recurring maintenance costs
will be about $1, 200 per year. The payback period for
microwave is 4.5 years without allowing for tariff
increases and without a present value analysis. Since
the useful life of a point to point microwave system is
at least ten years, microwave is a better choice than
telephone lines.
A major site in the mountains rather than near the Milton
Reservoir is even further and therefore, the payback
period for a microwave link will be even shorter.
A site near US 85 in the North would have about nine
stations and would be about 38 miles from the
communications center. The payback period for microwave
is 1.9 years (Microwave cost estimate is $58 ,000 ) .
The Grover site is 45 miles from the communications
center. Eight circuits (including four at the CO 71
site) might be needed' to the - Grover site. A midpoint
relay may be required to reach the Grover site. Without
a relay, the payback period for microwave is 1.75 years
(Microwave cost estimate is $56 ,000 ) . With a relay, the
payback is 2.8 years.
The path from the Grover site to the CO 71 site is 20
miles long. The payback for four circuits over this
distance is 6.3 years (Microwave cost estimate is
$48,000 ) .
-24-
The South site is 28 miles from the communications
center. For five circuits to this site, the microwave
payback period is 3. 9 years (Microwave cost estimate is
$50, 000 ) .
The distance between the Empire Tower site and the
communications center is 2 3/4 miles. For five circuits
to this site for back up, the microwave payback period is
21.1 years (Microwave cost estimate is $50 ,000 ) .
-25-
SECTION IV
COMMUNICATIONS CENTER
A. CAPABILITIES OF EXISTING CONSOLES
There are three Motorola Centracom communications control
consoles in the Weld County Regional Communications
Center located in the Centennial Office Building in
Greeley. The Centracom series consoles ended a nine year
production life cycle in 1983 , however spare parts will
be manufactured until approximately 1990.
These consoles have all of the capabilities in terms of
radio station operation, that are needed in Weld County,
however, as discussed later, more channel control modules
may need to be added.
B. REMAINING LIFE OF EXISTING CONSOLES
The existing consoles are about seven years old and are
in good condition. They should continue to provide
service at an acceptable level with low to moderate
maintenance cost until spare parts availability begins to
be a problem after about 1990.
C. EFFECTS OF TRAFFIC GROWTH
The present communications center operating procedure
requires that the same person receive information from
telephone callers and operate the radio console. The
LEAA methodology referenced in Section II of this report
shows that the dispatcher will be saturated when 11 new
events are initiated during the busiest hours when using
that operating procedure. Two dispatchers can handle 22
new events during busiest hours and that will occur at
about 1991. At that time, the operating procedure should
be changed so that different persons talk with callers
and operate the radio consoles.
-26-
Three radio consoles and three or four telephone operator
work stations will be required. It is probable that
telephone call volume into the public safety
communications center will be so high that the present
answering by telephone console attendants will be
discontinued. That will result in the need for three or
four telephone answering persons in the communications
center during the busiest hours.
As indicated in Section II.A.1. of this report, event
volume during the busiest .hours is expected to be about
27 events in 1995 . Radio console operators can perform
satisfactorily while handling up to 25 new events during
the busiest hours if they do not answer incoming
telephone calls and do not handle officer information
inquiries. In 1995 , with 27 law enforcement events
during busiest hours, two dispatchers will be only 55%
fully utilized. These dispatchers will also handle fire
and EMS events and provide radio service to Road and
Bridge personnel during the evening when the busiest
hours occur. The fire and EMS traffic volume is about
15% of the total for law enforcement, fire and EMS
traffic volume. Therefore, in 1995 , we estimate that two
radio operators will be 65% to 70% fully utilized during
the busiest hours. That would leave a comfortable factor
for growth in activity level out to the expected useful
life of a new communications center in the 2000 to 2005
time frame.
The present communications center space is not adequate
for three radio control consoles and three or four
telephone answering work stations. Therefore, we
recommend that Weld County plan on remodeling space for a
new communications center to be ready by the end of
1990. New consoles should be purchased and installed in
that space and the present consoles and communications
center space abandoned at that time.
-27-
The space required will be about twice the size of the
present space or about 1700 square feet. A reasonable
estimate for remodeling costs for this kind of space in
1990 is $150 per square foot or a total cost of
$250 ,000. Communications control consoles, telephone
answering personnel work stations and other equipment
will cost about $225,000 in 1990 . The 1700 square foot
space estimate does not include space for offices,
computer equipment, radios or voice recorders.
D. MODIFICATIONS TO EXISTING -CONSOLES
The communications center should have the ability to
communicate on FERN. This can be accomplished by adding
a base station at the communications center if the
mountaintop primary site alternative is selected. The
base station should be located at the Milton Reservoir
site if that option is selected.
Channel control modules for this and for the other
stations discussed in this report must be added to the
radio control consoles. By the addition of a channel
control module panel, up to 11 more channel control
modules can be added to each console. Channel control
modules cost about $1, 250 each installed.
-28-
r
SECTION V
PROJECT STAGING
The radio system changes need not be implemented all at once.
The changes can be accomplished in steps spread over several
years. This section of the report describes a set of
implementation steps that can be performed one at a time. In
laying out these steps, it is assumed that the decisions made
will result in staying in the presently used frequency bands
and that use of a new 400 foot high tower Northeast of the
Milton Reservoir will be the choice.
A. STEP ONE
The first step in the implementation is the licensing of
the additional radio frequencies needed. If this can not
be accomplished, the overall plan must be reevaluated.
B. STEP TWO
The most serious problem with the current system is radio
coverage. Therefore, when the necessary radio
frequencies are available, the 400 foot tower near Milton
Reservoir and four satellite receiver sites should be
constructed with point to point radio control links. The
site at Horsetooth Mountain may be retained until funding
is available for the US 85 site implementation. The
conversion from low band vhf to uhf should probably be
accomplished at this time. Back up coverage should also
be provided in this step.
-29-
C. STEP THREE
Replace mobile and portable radios that have reached the
end of their useful life and add tone coded squelch to
radios that are to be retained. Note that this will
require users to replace or modify radio equipment by a
specific date as fixed location radios will be modified
to operate only with tone coded squelch after that date
to eliminate interference for all users. Continue to
replace radios each year as they reach the end of their
useful life.
D. STEP FOUR
Complete the conversion to the final fixed location radio
sites and add the remaining satellite receivers.
E. STEP FIVE
Implement a new communications center in 1991.
