' This study assessed the impacts of the Generalcare Health Services
Medical Clinic development on the short range and long range street
system in the vicinity of the proposed development. As a result of this
analysis, the following is concluded:
' - The development of Generalcare Health Services Medical Clinic
is feasible from a traffic engineering standpoint. At full
development, the Generalcare Health Services Medical Clinic
will generate approximately 296 daily trip ends, 20 morning
peak hour trip ends, and 30 afternoon peak hour trip ends.
' - Current operation at the key intersections is acceptable.
Acceptable operation at signalized and unsignalized
intersections during the peak hours is defined as level of
service D or better.
- It is expected that no traffic signals will be warranted at
the Lemay/Poudre River intersection.
- In the short range future, given full development of the
Generalcare Health Services Medical Clinic and an increase in
background traffic, all key intersections will operate
' - acceptably. The short range geometry is shown in Figure 11.
In the long range future, given full development of
Generalcare Health Services Medical Clinic, the key
intersections will operate acceptably during the peak hours.
The long range geometry is shown in Figure 12.
' - Acceptable level of service is achieved for pedestrian,
bicycle, and transit modes based upon the measures in the
multi -modal transportation guidelines.

' Pedestrian Level of Service
' Appendix G shows a map of the area that is within 1320 feet of
the Generalcare Health Services Medical Clinic. There will be two
pedestrian destinations within a quarter mile of. the Generalcare
Health Services Medical Clinic. These are the commercial uses in the
' southwest quadrant of the Lemay/Riverside intersection which consists
of Albertson's and Long's Drug, and the various commercial uses along
the east side of Lemay Avenue. This site is in an area type termed
' "activity center." The level of service determination assumes that
future developments will build their streets in accordance with Fort
Collins Standards. This being the case, pedestrian facilities will
exist where they currently do not. This is a reasonable assumption.
The Pedestrian LOS Worksheet is provided in Appendix
G. The
minimum
level of service for "activity center" is B for
all
measured
categories.
'
Bicycle Level of Service
Based upon Fort Collins bicycle LOS criteria,
there
is one
'
destination area within 1320 feet of the Generalcare
Health
Services
Medical Clinic. This destination area is the commercial
center
that is
in the southwest quadrant of the Lemay/Riverside intersection.
A
bicycle LOS worksheet is provided in Appendix G.
This
site is
'
directly connected to bike lanes on Lemay Avenue and the Poudre
River
Trail.
' Transit Level of Service
' Currently, there is limited transit service in the area. In the
future, transit service will be improved. In the future, Lemay
Avenue will have 20 minute transit service and Riverside Avenue will
have 30 minute transit service. It is anticipated that the level of
service will be in the D category with implementation of the City's
Transit Development Plan. A future transit level of service
worksheet is provided in Appendix G.

Trip Assignment
Trip assignment is how the generated and distributed trips are
expected to be loaded on the street system. The assigned trips are the
resultant of the trip distribution process. Figure 8 shows the site
generated peak hour traffic assignment. Figure 9 shows the total (site
plus background) short range peak hour traffic at the key intersections.
' Figure 10shows the total long range morning and afternoon peak hour
traffic at the key intersections.
' Signal Warrants
As a matter of policy, traffic signals are not installed at any
location unless warrants are met according to the Manual on Uniform
Traffic Control Devices. No signal warrants are expected to be met at
the Lemay/Poudre River intersection.
1 Operation Analysis
Capacity analyses were performed on key intersections adjacent to
the Generalcare Health Services Medical Clinic. The operations analyses
were conducted for the short range analysis, reflecting a year 2001
condition. The long range analysis reflects a year 2020 condition.
Using the traffic volumes shown in Figure 6, the key intersections
operate in the short range background condition as indicated in Table 3.
Calculation forms for these analyses are provided in Appendix C. The
key intersections will operate acceptably during the peak hours.
Using the traffic volumes shown in Figure 7, the key intersections
operate in the long range background condition as indicated in Table 4.
' Calculation forms for these analyses are provided in Appendix D. The
key intersections will operate acceptably during the peak hours.
Using the traffic volumes shown in Figure 9 and the recommended
geometrics, the intersections operate in the short range total
condition as indicated in Table 5. Calculation forms for these
analyses are provided in Appendix E. The key intersections will
operate acceptably. The short range geometry is shown in Figure 11.
The afternoon peak hour northbound left turns is forecasted at 255
vehicles and 305 vehicles in the respective peak hours. A "rule of
thumb" gauge indicates that dual left -turn lanes should be considered
' when the number of left turns is greater than 300 vehicles per hour.
The afternoon peak hour forecast exceeds this threshold. Dual
northbound left -turn lanes are not recommended, since acceptable
operation is achieved with a single left -turn lane. Traffic
' operation and stacking should be monitored to determine whether dual
left -turn lanes should be implemented.
Using the traffic volumes shown in Figure 10 and recommended
geometrics, the intersections operate in the long range total
condition as indicated in Table 6. Calculation forms for these
analyses are provided in Appendix F. The key intersections will operate
acceptably. The long range geometry is shown in Figure 12,

III. PROPOSED DEVELOPMENT
The Generalcare Health Services Medical Clinic is a medical clinic
development, located in the southeast quadrant of the Lemay/Poudre River
Drive intersection in Fort Collins. Figure 4 shows a site plan of the
I Generalcare Health Services Medical Clinic. The short range analysis
(Year 2001) includes development of the Generalcare Health Services
Medical Clinic and an increase in background traffic. The long range
analysis year is considered to be 2020.
Trip Generation
' Trip generation is important in considering the impact of a
development such as this upon the existing and proposed street system. A
compilation of trip generation information contained in Trip Generation,
1 6`" Edition, ITE was used to estimate trips that would be generated by
the proposed/expected uses at this site. Table 2 shows the expected
trip generation on a daily and peak hour basis. This development is
described as a medical clinic. The trip generation information
contained in the cited reference is limited for the medical clinic land
use. Since the trip generation rates are comparable, but the data for
medical office is more reliable, this was used to forecast the trip
generation for this land use.

Trip Distribution
Directional distribution of the generated trips was determined for
the Generalcare Health Services Medical Clinic based upon the
distribution of the existing medical office. Figure 5 shows the trip
distributions used.
IBackground Traffic Projections
Figures 6 and 7 show the respective short range and long range
background traffic projections. Background traffic projections for the
short range and long range future horizons were obtained by reviewing
the NFRRTP and the Walmart traffic study prepared for this area of Fort
Collins. The traffic growth rate was determined to be 1 percent per
' year, except during the afternoon peak hour on Lemay Avenue. The
afternoon peak hour traffic was increased to reflect the Walmart
Superstore, proposed north of Mulberry Street.

IExisting Operation
The key intersections were evaluated using techniques provided in
the 1997 Highway Capacity Manual. The peak hour operation is shown in
Table 1. Calculation forms are provided in Appendix B. A description
of level of service for signalized and unsignalized intersections from
the 1997 Highway Capacity Manual is also provided in Appendix B. The
key intersections operate acceptably during both the morning and
afternoon peak hours. Acceptable operation at signalized and
unsignalized intersections during the peak hours is defined as level of
service D or better. Experience indicates that if level of service D
can be achieved during the peak hours, operation will be at level of
service C or better for 20-22 hours of an average weekday.

Pedestrian Facilities
There are pedestrian facilities along both sides of Lemay
Avenue. There are also sidewalks along the entire length of Poudre
River Drive. Along Riverside Avenue, sidewalks exist only on the
south side. This site is within 1320 feet of existing residential
areas east of this site. It is also within 1320 feet of existing
commercial uses to the south of the site. Pedestrian activity at the
key intersections was observed and found to be relatively light in
volume. Sidewalks are/will be incorporated in this development.
Bicycle Facilities
There are bicycle facilities along Lemay Avenue. Along Riverside
Avenue, bike lanes exist on the south side only. There are no bike
lanes along Poudre River Drive, since it is a local street. Poudre
River Drive is wide enough for bicyclists to operate safely. A
Poudre River trailhead is on Lemay Avenue, just north of Poudre River
Drive.
Transit Facilities
Route 9 is within 1320 feet of this site. It operates on Lemay
Avenue and Riverside Avenue. Route 9 provides year-round service on
60 minute headways between 6:30am and 6:30pm.

II. EXISTING CONDITIONS
The location of the Generalcare Health Services Medical Clinic is
shown in Figure 1. It is important that a thorough understanding of the
existing conditions be presented.
Land Use
Land uses in the area are primarily either commercial,
residential, or business/office. Commercial uses exist to the south
across Riverside Avenue. Residential uses are east of the site. There
is an existing medical office north of the Generalcare Health Services
Medical Clinic site. Land in the area is flat (<3% grade) from a
traffic operations perspective. The center of Fort Collins lies to the
south of Generalcare Health Services Medical Clinic.
Roads
The primary streets near the Generalcare Health Services Medical
Clinic are Lemay Avenue, Riverside Avenue, and Poudre River Drive. Lemay
Avenue is to the west of the Generalcare Health Services Medical Clinic.
It is a north -south street designated as an arterial in the Fort Collins
Master Street Plan. Lemay Avenue has a four lane cross section with a
raised center median north and south of Riverside Drive. There is a
left -turn lane on Lemay Avenue, approaching Poudre River Drive. The
existing speed limit in this area is 35 mph.
Riverside Avenue is south of the Generalcare Health Services
Medical Clinic. It is an east -west street designated as an arterial on
the Fort Collins Master Street Plan. It is has a four lane cross
section with a center -turn lane at Lemay Avenue. The posted speed on
Riverside Avenue is 35 mph. The Lemay/Riverside intersection has signal
control.
Poudre River Drive is north of the Generalcare Health Services
Medical Clinic. It is an east -west street designated as a local street
on the Fort Collins Master Street Plan. It is a two lane road adjacent
to the site. The Lemay/Poudre River intersection has stop sign control.
Approximately 250 feet east of Lemay Avenue, Poudre River Drive turns to
the south and becomes Hoffman Mill Road. The Generalcare Health
Services Medical Clinic takes access from Hoffman Mill Road.
Existing Traffic
Recent peak hour turning movements at the key intersections are
shown in Figure 2. Raw traffic count data is provided in Appendix A.
The traffic data at the Lemay/Riverside intersection was collected in
April 1999. The traffic data at the Lemay/Poudre River intersection was
collected in March 2000. Therefore, the traffic volumes were adjusted
and balanced between intersections and is shown in Figure 3.
