I. INTRODUCTION
This transportation impact study (TIS) addresses the capacity, geometric, and
control requirements for the proposed Spring Creek Farms North residential development.
The proposed Spring Creek Farms North is located north of Drake Road between Joseph
Allen Drive and the Union Pacific Railroad tracks in Fort Collins, Colorado.
During the course of the analysis, numerous contacts were made with the
owner/developer (SC Residential, LLC), the project engineering consultant (Aspen
Engineering), the project planning consultant (Vignette Studios), Fort Collins Traffic
Engineering, and Fort Collins Transportation Planning. The Transportation Impact Study
Base Assumptions form and related documents are provided in Appendix A. This study
generally conforms to the format set forth in the Fort Collins TIS Guidelines in the “Larimer
County Urban Area Street Standards” (LCUASS). A scoping discussion was held with the
Fort Collins Traffic Engineering staff. Due to the trip generation, this is a intermediate
transportation impact study. The study involved the following steps:
- Collect physical, traffic, and development data;
- Perform trip generation, trip distribution, and trip assignment;
- Determine peak hour traffic volumes;
- Conduct capacity and operational level of service analyses on key intersections;
- Analyze signal warrants;
- Conduct level of service evaluation of pedestrian, bicycle, and transit modes of
transportation

II. EXISTING CONDITIONS
The location of the Spring Creek Farms North 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 commercial, residential, or open. There are
residential uses to the west, east, and south of the site. There are commercial uses to
the southeast (Rigden Farm Commercial) and northeast (Timberline Commercial) of the
site. The Fort Collins Police Services Building is east of the site. The Fort Collins
Police Services Building was part of the original Spring Creek Farms North. The Spring
Creek Farm apartments bordered by Drake Road, Charles Brockman Drive, Timberline
Road, and Joseph Allen Drive is currently being constructed. The Spring Creek Farms
North site is currently vacant. The center of Fort Collins lies to the west of the proposed
Spring Creek Farms North site.
Streets
The primary streets near the Spring Creek Farms North site are Timberline Road,
Drake Road, Nancy Gray Avenue, Joseph Allen Drive, and Charles Brockman Drive.

It was determined that the Nancy Gray/Joseph Allen and Charles
Brockman/Joseph Allen intersections would operate acceptably and that they did not
need to be analyzed.
Existing Traffic
Recent peak hour traffic volumes at the key intersections are shown in Figure 3.
The counts at the Timberline/Drake intersection were obtained in April 2013 by the City
of Fort Collins. The counts at the Timberline/Nancy Gray intersection were obtained in
February 2013 by the City of Fort Collins. The counts at the Timberline/Charles
Brockman-Katadin and Drake/Sagebrush intersections were obtained in January 2012.
These are greater than one year old. However, since there was significant construction
traffic at these intersections, these counts were used with adjustments related to the
through traffic. Raw traffic count data is provided in Appendix B. Since the traffic
counts were done on different days, the intersection volumes were balanced using the
Timberline/Drake and Timberline/Nancy Gray intersection to determine the through
volumes on Timberline Road and Drake Road. Figure 4 shows the adjusted/balanced
recent peak hour traffic volumes.
Existing Operation
The Timberline/Drake, Timberline/Nancy Gray, Timberline/Charles Brockman-
Katadin, and Drake/Sagebrush intersections were evaluated and the peak hour
operation is displayed in Table 1. Calculation forms are provided in Appendix C. The
Timberline/Drake, Timberline/Nancy Gray, Timberline/Charles Brockman-Katadin, and
Drake/Sagebrush intersections are currently operating acceptably with existing control
and geometry in the morning and afternoon peak hours, except for the westbound
approach at the Timberline/Drake intersection in the morning peak hour. An adjustment
to the City’s current signal timing splits results in acceptable operation. No other
adjustments were made. This operation is shown in parentheses in Table 1. The
intersections were evaluated using techniques provided in the 2000 Highway Capacity
Manual. A description of level of service for signalized and unsignalized intersections
from the 2000 Highway Capacity Manual and a table showing the Fort Collins Motor
Vehicle LOS Standards (Intersections) are also provided in Appendix C. At the
Drake/Sagebrush intersection, the calculated delay for the northbound approach was
commensurate with level of service E in the morning peak hour and F in the afternoon
peak hour. The Spring Creek Farms North site is in an area termed “mixed use
districts.” In areas termed “mixed use districts,” acceptable operation at signalized
intersections during the peak hours is defined as level of service E or better. At
unsignalized intersections, acceptable operation is considered to be at level of service F
for any approach leg for an arterial/local intersection. In such areas, it is expected that
there would be substantial delays to the minor street movements at unsignalized
intersections during the peak hours. This is considered to be normal and acceptable in
urban areas.

III. PROPOSED DEVELOPMENT
The Spring Creek Farms North is a residential development with 76 single family
dwelling units, located in the northwest quadrant of the Drake/Sagebrush-Joseph Allen
intersection in Fort Collins. Figure 5 shows a site plan of the Spring Creek Farms North.
The short range analysis (Year 2018) includes development of the Spring Creek Farms
North and an appropriate increase in background traffic due to normal growth and other
potential developments in the area. The site plan shows that the Spring Creek Farms
North will use Nancy Gray Avenue and Charles Brockman Drive to access Timberline
Road. The Spring Creek Farms North will also have access to Drake Road with the
continuation of Joseph Allen Drive to the Drake/Sagebrush intersection.
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
contain in Trip Generation, 9th Edition, ITE was used to estimate the trips that would be
generated by the proposed/expected uses at the Spring Creek Farms North site. A trip is
defined as a one-way vehicle movement from origin to destination. Table 2 shows the
expected trip generation on a daily and peak hour basis. The trip generation of the Spring
Creek Farms North development resulted in 816 daily trip ends, 63 morning peak hour trip
ends, and 82 afternoon peak hour trip ends.

Trip Distribution
Trip distribution for the Spring Creek Farms North was based on existing/future
travel patterns, land uses in the area, consideration of trip attractions/productions in the
area, and engineering judgment. Figure 6 shows the trip distribution for the short range
(2018) analysis future. The trip distribution was agreed to by City of Fort Collins staff in
the scoping discussions.

Background Traffic Projections
Figure 7 shows the short range (2018) background traffic projections.
Background traffic projections for the short range future horizon were obtained by
reviewing the North Front Range Regional Transportation Plan and various traffic
studies prepared for this area of Fort Collins. The other traffic studies in this area are
Timberline Commercial, Spring Creek Farm, and Bucking Horse (Filings 1 and 2).
Based upon these sources, it was determined that traffic volumes on Timberline Road
and Drake Road, would increase by approximately 2.0% per year in the short range
future. It was assumed that Spring Creek Farms, Bucking Horse Filing One and Filing
Two, and half of Timberline Commercial would be developed in the short range future.
This traffic was added to the short range (2018) background traffic volumes. The
background traffic growth was agreed to by City of Fort Collins staff in the scoping
discussions.
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 short range (2018) total (site plus background) peak hour traffic assignment.
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. The
Timberline/Drake and Timberline/Nancy Gray intersections are currently signalized. The
Timberline/Charles Brockman-Katadin and Drake/Sagebrush-Joseph Allen intersections
will not have traffic signals in the future.
Operation Analysis
Operation analyses were performed at the Timberline/Drake, Timberline/Nancy
Gray, Timberline/Charles Brockman-Katadin, and Drake/Sagebrush-Joseph Allen
intersections. The Timberline/Drake intersection was analyzed with the required
westbound right-turn lane in the short range (2018) future. The operations analyses were
conducted for the short range future, reflecting the year 2018 condition.
Using the traffic volumes shown in Figure 7, the Timberline/Drake,
Timberline/Nancy Gray, Timberline/Charles Brockman-Katadin, and Drake/Sagebrush-
Joseph Allen intersections operate in the short range (2018) background traffic future as
indicated in Table 3. Calculation forms for these analyses are provided in Appendix D.
The key intersections will operate acceptably with the existing control and required

geometry. At the Drake/Sagebrush-Joseph Allen intersection the calculated delay for the
northbound and southbound approaches was commensurate with level of service E/F in
the morning and afternoon peak hours. This is considered to be normal and acceptable
during the peak hours at stop sign controlled intersections along arterial streets.
Using the traffic volumes shown in Figure 9, the Timberline/Drake,
Timberline/Nancy Gray, Timberline/Charles Brockman-Katadin, and Drake/Sagebrush-
Joseph Allen intersections operate in the short range (2018) total traffic future as
indicated in Table 4. Calculation forms for these analyses are provided in Appendix F.
The key intersections will operate acceptably with existing control and required geometry.
At the Drake/Sagebrush-Joseph Allen intersection the calculated delay for the northbound
and southbound approaches was commensurate with level of service E/F in the morning
and afternoon peak hours. This is considered to be normal and acceptable during the
peak hours at stop sign controlled intersections along arterial streets.
Geometry
Figure 10 shows a schematic of the required short range (2018) geometry. This is
the existing geometry at the Timberline/Nancy Gray, and Timberline/Charles Brockman-
Katadin intersections. At the Timberline/Drake intersection a westbound right-turn lane
is required per LCUASS Figure 8-4 with the current traffic. At the Drake/Sagebrush-
Joseph Allen intersection it is recommended that the Sagebrush Drive-Joseph Allen
Drive legs have a northbound and southbound left-turn lane and a northbound and
southbound through/right-turn lane. A westbound right-turn lane is also required at this
intersection. The lanes at the Drake/Sagebrush-Joseph Allen intersection are currently
being constructed.
Pedestrian Level of Service
Appendix H shows a map of the area that is within 1320 feet of the Spring Creek
Farms North development. There will be six pedestrian destinations within 1320 feet of
the Spring Creek Farms North development. These are: 1) the residential area to the
east of the site (Sidehill), 2) the Fort Collins Police Services Building within the site, 3)
the residential area to the west of the site, 4) the commercial area (Timberline
Commercial to the north of the site, 5) the commercial area (Rigden Farms) to the
southeast of the site, and 6) the residential area to the south of the site. This site is in
an area type termed “transit corridor.” Acceptable pedestrian level of service will be
achieved for all pedestrian destinations. The Pedestrian LOS Worksheet is provided in
Appendix H. The minimum level of service for “transit corridor” is B, except for Visual
Interest & Amenities which is C.

Bicycle Level of Service
Appendix H shows a map of the area that is within 1320 feet of the Spring Creek
Farms North development. There will be two bicycle destinations within 1320 feet of the
Spring Creek Farms North development. These are: 1) the commercial area
(Timberline Commercial) to the north of the site and 2) the commercial area (Rigden
Farms) to the southeast of the site. The Bicycle LOS Worksheet is provided in
Appendix H. The minimum level of service for this site is C. This site is connected to
Timberline Road and Drake Road. Therefore, it is concluded that level of service C can
be achieved. The Power Trail is just west of the Union Pacific Railroad.
Transit Level of Service
This area of Fort Collins is served by Transfort Route 17. This route has transit
stops just north of the Timberline/Drake intersection, just south of the
Timberline/Charles Brockman-Katadin intersection, and just north of the
Timberline/Nancy Gray intersection, which are near this site.

IV. CONCLUSIONS
This study assessed the impacts of the Spring Creek Farms North on the street
system in the vicinity of the proposed development in the short range (2018) future. As a
result of this analysis, the following is concluded:
- The development of the Spring Creek Farms North is feasible from a traffic
engineering standpoint. At full development, the Spring Creek Farms North will
generate approximately 816 daily trip ends, 63 morning peak hour trip ends, and 82
afternoon peak hour trip ends.
- The Timberline/Drake and Timberline/Nancy Gray intersections are currently
signalized. The Timberline/Charles Brockman-Katadin and Drake/Sagebrush-
Joseph Allen intersections will not have traffic signals in the future.
- In the short range (2018) future, given development of the Spring Creek Farms
North and an increase in background traffic, the Timberline/Drake,
Timberline/Nancy Gray, Timberline/Charles Brockman-Katadin, and
Drake/Sagebrush-Joseph Allen intersections will operate acceptably with the
existing geometry and control.
- The short range (2018) geometry is shown in Figure 10. At the Timberline/Drake
intersection a westbound right-turn lane is required with the current traffic. At the
Drake/Sagebrush-Joseph Allen intersection it is recommended that the
Sagebrush Drive-Joseph Allen Drive legs have a northbound and southbound
left-turn lane and a northbound and southbound through/right-turn lane. A
westbound right-turn lane is also required at this intersection.
- Acceptable level of service is achieved for pedestrian, bicycle, and transit modes
based upon the measures in the multi-modal transportation guidelines and future
improvements to the street system in the area.
