I. INTRODUCTION
This intermediate transportation impact study (TIS) addresses the capacity,
geometric, and control requirements for the proposed Redtail Ponds Residential
Development. The proposed Redtail Ponds Residential Development is located west of
College Avenue (US287) between Fairway Lane and Cameron Drive in Fort Collins,
Colorado.
During the course of the analysis, numerous contacts were made with the project
planning architect (Architecture West), 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 an 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 Redtail Ponds Residential 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/office and residential.
Commercial/office uses exist adjacent to the site, to the north, and to the northeast
across College Avenue. Residential uses exist east of the site across College Avenue
and west of the site, across the railroad tracks. The center of Fort Collins lies to the
north of the Redtail Ponds Residential development. The Redtail Ponds Residential site
is in an area termed “commercial corridor.”
Streets
The primary streets near the Redtail Ponds Residential site are College Avenue,
Fossil Creek Parkway, Cameron Drive, and Fairway Lane. Figure 2 shows a schematic
of the existing geometry at the key intersections.
College Avenue is east of (adjacent to) the proposed Redtail Ponds Residential
site. It is a north-south street classified as a six-lane arterial on the Fort Collins Master
Street Plan. Currently, College Avenue has a four-lane cross section with appropriate
auxiliary lanes. At the College/Fossil Creek-Cameron intersection, College Avenue has
a northbound and a southbound left-turn lane, two through lanes in each direction, and
a northbound and a southbound right-turn lane. At the College/Fairway intersection,
College Avenue has a northbound and a southbound left-turn lane, two through lanes in
each direction, and a northbound and a southbound right-turn lane. The College/Fossil
Creek-Cameron intersection has signal control. The College/Fairway intersection is
stop sign controlled on Fairway Lane. The posted speed changes just to the south of
the College/Fairway intersection. The posted speed is 50 mph to the north of the
intersection and 55 mph to the south of the intersection.
Fossil Creek Parkway is south of the proposed Redtail Ponds Residential site. It
is an east-west street classified as a collector street on the Fort Collins Master Street
Plan. Currently, Fossil Creek Parkway has a two-lane cross section. Fossil Creek
Parkway lines up with Cameron Drive, which is west of College Avenue. At the
College/Fossil Creek-Cameron intersection, Fossil Creek Parkway has a westbound
left-turn/through lane and a westbound right-turn lane. The posted speed on this
segment of Fossil Creek Parkway is 25 mph.

Cameron Drive is south of the proposed Redtail Ponds Residential site. It is an
east-west street classified as a local street on the Fort Collins Master Street Plan.
Currently, Cameron Drive has a two=lane cross section. At the College/Fossil Creek-
Cameron intersection, Cameron Drive has an eastbound left-turn lane, an eastbound
through lane, and an eastbound right-turn lane. Only the left-turn lane is striped,
however they function as mentioned above. There is an unnamed frontage road just
west (25 feet) of College Avenue. There is no posted speed on Cameron Drive.
Fairway Lane is north of the proposed Redtail Ponds Residential site. It is an
east-west street classified as a local street on the Fort Collins Master Street Plan.
Currently, Fairway Lane has a two-lane cross section. At the College/Fairway
intersection, Fairway Lane has a left-turn lane, a through lane, and a right-turn lane
eastbound, and a left-turn/through lane and right-turn lane westbound. The westbound
leg is not striped, however they function as mentioned above. There is no posted speed
on this segment of Fairway Lane.
Existing Traffic
Recent peak hour traffic volumes at the College/Fossil Creek-Cameron and
College/Fairway intersections are shown in Figure 3. The counts at the College/Fossil
Creek-Cameron and College/Fairway intersections were obtained in July 2013. Raw
traffic count data is provided in Appendix B. Since the traffic counts were done on
different days, the traffic volumes were balanced between the two key intersections.
Figure 4 shows the adjusted/balanced recent peak hour traffic volumes.
Existing Operation
The College/Fossil Creek-Cameron and College/Fairway intersections were
evaluated and the peak hour operation is displayed in Table 1. Calculation forms are
provided in Appendix C. The College/Fossil Creek-Cameron intersection is currently
operating acceptably with existing control and geometry in the morning and afternoon
peak hours. The College/Fairway intersection is currently not operating acceptably.
The intersections were evaluated using techniques provided in the 2010 Highway
Capacity Manual. A description of level of service for signalized and unsignalized
intersections from the 2010 Highway Capacity Manual and a table showing the Fort
Collins Motor Vehicle LOS Standards (Intersections) are also provided in Appendix C.
At the College/Fairway intersection, the calculated delay for the eastbound and westbound
approach was commensurate with level of service E/F in the morning and afternoon peak
hours. The Redtail Ponds Residential site is in an area termed “commercial corridors.”
In areas termed “commercial corridors,” acceptable overall operation at signalized
intersections during the peak hours is defined as level of service D or better. At
signalized intersections, acceptable operation of any leg and any movement is level of
service E. At unsignalized intersections, in commercial corridors, there is no minimum
level of service criteria. In other TIS’, Fort Collins staff has indicated that level of service
E is considered to be acceptable. This is considered to be normal and acceptable in
urban areas.

Pedestrian Facilities
Pedestrian facilities in this area are sporadic. Sidewalks exist on Fossil Creek
Parkway and Cameron Drive. There is access with handicap ramps to the Mason Trail
to the west of the site and Fossil Creek Trail is to the south of the site. Sidewalks will be
incorporated within and adjacent to this development.
Bicycle Facilities
There are bicycle lanes along College Avenue and Fossil Creek. Bike lanes are
not required on local streets. The Mason Trail is to the west of the site and Fossil Creek
Trail is to the south of the site.
Transit Facilities
Currently, the FLEX is within 1320 feet of the site. FLEX is a regional route
operating between Fort Collins and Longmont. There are stops in Fort Collins,
Loveland, Berthoud, and Longmont.

III. PROPOSED DEVELOPMENT
The Redtail Ponds Residential is a residential development with 60 apartment
dwelling units and an office for support staff, located on College Avenue between
Cameron Drive and Fairway Lane in Fort Collins. Figure 5 shows a site plan of the
Redtail Ponds Residential. The short range analysis (Year 2018) includes development
of the Redtail Ponds Residential and an appropriate increase in background traffic due
to normal growth and other potential developments in the area. The site plan shows
that the Redtail Ponds Residential will have access to both Fairway Lane and Cameron
Drive. The signalization of the College/Fairway intersection will encourage the Redtail
Ponds Residential traffic to use the College/Fairway intersection and not travel through
the Cameron Park development.
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 Redtail Ponds Residential site. Redtail
Ponds Residential is an affordable housing development. Therefore, it is likely that
many residences will use the MAX and FLEX transit services. However, to be
conservative no reduction in the number of vehicle trips was requested. 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 Redtail Ponds
Residential development resulted in 552 daily trip ends, 42 morning peak hour trip ends,
and 56 afternoon peak hour trip ends.

Trip Distribution
Trip distribution for the Redtail Ponds Residential 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, CDOT 20-year factors,
and various traffic studies prepared for this area of Fort Collins. Based upon these
sources, it was determined that traffic volumes on College Avenue, would increase by
approximately 1.5% per year in the short range future. Traffic from the South Transit
Center/BRT Station (to the north of Fairway Lane) 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 College/Fossil
Creek-Cameron intersection is currently signalized. The College/Fairway intersection will
meet the peak hour warrant in the afternoon peak hour in the short range (2013) future.
The peak hour signal warrant analysis is in Appendix D. Therefore, the College/Fairway
intersection was analyzed as a signal in the short range (2018) future.
Operation Analysis
Operation analyses were performed at the College/Fossil Creek-Cameron and
College/Fairway intersections. The operations analyses were conducted for the short
range future, reflecting the year 2018 condition.
Using the traffic volumes shown in Figure 7, the College/Fossil Creek-Cameron and
College/Fairway intersections operate in the short range (2018) background traffic future
as indicated in Table 3. Calculation forms for these analyses are provided in Appendix E.
The key intersections will operate acceptably in the morning and afternoon peak hours.
Using the traffic volumes shown in Figure 9, the College/Fossil Creek-Cameron and
College/Fairway 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 in the morning and afternoon peak hours.

Geometry
Figure 10 shows a schematic of the required short range (2018) geometry. This is
the existing geometry at the College/Fossil Creek-Cameron and College/Fairway
intersections.
Pedestrian Level of Service
Appendix G shows a map of the area that is within 1320 feet of the Redtail Ponds
Residential development. There will be five pedestrian destinations within 1320 feet of
the Redtail Ponds Residential development. These are: 1) the office area (Cameron
Park and Fossil Creek Office Park) adjacent to the site, 2) the commercial area north of
the site, 3) the commercial/office area northeast of the site, 4) the residential area
(Fossil Creek) to the east of the site, and 5) the South Transit Center DEIS Commuter
Rail/BRT Station to the north of the site. This site is in an area type termed “transit
corridor.” The minimum level of service for “transit corridor” is B for Directness and
Security and level of service C for Continuity, Street Crossings, and Visual Interest &
Amenities. Acceptable pedestrian level of service is achieved for all pedestrian
factors. The Pedestrian LOS Worksheet is provided in Appendix G.
Bicycle Level of Service
Appendix G shows a map of the area that is within 1320 feet of the Redtail Ponds
Residential development. There will be two bicycle destinations within 1320 feet of the
Redtail Ponds Residential development. These are: 1) the Mason Street/Fossil Creek
multi-use path to the west and south of the site and 2) the Max transit center to the
north of the site. The Bicycle LOS Worksheet is provided in Appendix G. The minimum
level of service for this site is C. This site is connected to College Avenue and the
Mason Street trail. Therefore, it is concluded that level of service C can be achieved.
Transit Level of Service
This area of Fort Collins is served by Flex. This area will be served by the MAX
in the short range future. According to TransFort, almost all southern bus routes will be
redirected to stop at the South Transit Center/BRT Station. This will encourage
residence to use transit for many other locations around Fort Collins and surrounding
communities.

IV. CONCLUSIONS
This study assessed the impacts of the Redtail Ponds Residential 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:
- Currently the College/Fossil Creek-Cameron intersection operates acceptably. The
College/Fairway intersection does not operate acceptably.
- The development of the Redtail Ponds Residential is feasible from a traffic
engineering standpoint. At full development, the Redtail Ponds Residential will
generate approximately 552 daily trip ends, 42 morning peak hour trip ends, and 56
afternoon peak hour trip ends.
- The College/Fossil Creek-Cameron intersection is currently signalized. The
College/Fairway intersection will meet the peak hour signal warrant in the short
range (2018) future.
- In the short range (2018) future, given development of the Redtail Ponds
Residential and an increase in background traffic, the College/Fossil Creek-
Cameron and College/Fairway intersections will operate acceptably with the
existing geometry and a signal at the College/Fairway intersection.
- The short range (2018) geometry is shown in Figure 10, this is the current
geometry.
- 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. The location of the South Transit
Center/BRT Station will encourage residence to use transit for many other
locations around Fort Collins and the surrounding communities.
