IX. Conclusion
This TIS assessed the impacts associated with the Choice Center Redevelopment
Project located at the intersection of College Avenue and Stuart Street in Fort
Collins, Colorado. The project is a mixed use development consisting of a specialty
retail redevelopment and student apartments. Based on the analyses, investigations,
and findings documented in the various sections of this Transportation Impact Study,
the following can be concluded.
o Current operation is acceptable at all of the key intersections.
o The Choice Center is expected to generate approximately 101 morning
trip ends, 225 afternoon trip ends, and 3048 daily trip ends.
o No new traffic signals or signal modifications will be required with the
construction of the project.
o The intersection of College Avenue and Parker should be reconstructed to
a '/< movement. Storage lengths should be 100 feet for the southbound
left turn and 120 feet for the northbound left turn.
o Traffic LOS for the short term build scenario is acceptable based on the
LUCASS standards.
o In terms of multi -modal LOS, the project will meet the transit and
pedestrian LOS. The bicycle LOS is not achievable since bikes are
prohibited on College Avenue and there are no bike lanes on Prospect
currently or in the foreseeable future. However, the project is at the
intersection of the Mason Corridor and Spring Creek trails and bicycle
access is excellent. A variance request to the standard is hereby
requested.
o A short connection to the Spring Creek Trail from the southern edge of
the property should be constructed.
o In the long-term future, the intersection of Prospect/College is expected to
fail standards for operation
o In the long-term future, the city should consider limited movements at the
northern access to right-in/right-out.
o No auxiliary lanes are required with this project.
o The project is feasible from a traffic engineering perspective and
improves the surrounding roadway network.
Statement of Adequacy: The transportation facilities will be adequate and available to
serve this development as contained in the Larimer County Urban Area Street Standards.
All applicable LOS standards will be met since all transportation facilities are in place or
will be in place upon issuance of a certificate of occupancy,.

Peak Load Factor: The standard for the peak load factor is calculated by
dividing the number of passengers by the peak time of day by the available seats.
The standard requires that this value be < 1.2. Based on the LOS Manual, for all
future routes, the presumed peak load factor is 1.0 and therefore the standard is
satisfied.
Based on the above, the transit LOS achieved 4 out of the 4 criteria and is therefore the
LOS is calculated at "A", which is obviously acceptable.

weekday frequency of service, travel time factor, and peak load factor. The LOS
standard for transit is `B" based on this site location being within a commercial corridor.
The 2010 transit plan shows that the site will have close access to the Mason BRT with
bike and pedestrian connections as well as being directly served by Routes 2. The
Mason BRT is proposed to have 10-minute service.
Hours of Weekday Service: Since the site is directly adjacent to the Mason
Corridor and a short walking distance to the Prospect Station, it is assumed that
the site will be served by 18 hours of service on an average weekday. The
standard can be assumed to be met.
Weekday Frequency of Service: Since the site is adjacent to an identified route
of high frequency transit service and the Mason Corridor, the minimum of 15-
minute service is met.
Travel Time Factor: The travel time factor is portal-to-portal travel time
divided by auto travel time (peak hour). The standard for the criteria is for the
travel time in bus to be no more than two times that of the automobile. This
standard is not met for the project. The BRT line will serve to increase the travel
time significantly over standard bus service. The standard is met for the CSU to
downtown trip, but not for the Mall or the Fort Collins High School trips.

improve the visual appearance of the site property, the surrounding area's lack of
visual appeal is a much larger project that cannot be addressed with this project.
Security — The sidewalks in the area are well lit and good sight distances are
available.
B. Bicycles Level of Service
The surrounding street system was evaluated for compliance with the City of Fort
Collins bicycle level of service standards. Acceptable LOS for bicycles is considered C.
To achieve LOS C, the project must have at least direct access to either north/south or
east/west on -street bike lanes.
Prospect Road and College Avenue do not have bike lanes as part of their geometrics.
Bicycles are prohibited on College Avenue and adding bike lanes on these two roadways
is outside the realm of this project or even a City Capital project at this time. The
bicycle LOS for the project has been calculated at D. 1 LEI ftc's N
�psornl G40-N,
The project will have excellent connectivity for bikes 'nce the site located at the
intersection of the Spring Creek bicycle trail and th Mason Corridor. he functionality
of the bicycle system at this location is outstan ' , irr ess of not meeting the
standard. It is recommended that the City grant a variance to the standard since the
functionality of the bicycle system at this location is high.
C. Transit Level of Service
According to the LUCASS Multimodal Level of Service Manual, transit level of service
for the City of Fort Collins is based on the routes and service levels planned for the year
2015. However, the Manual was written in 1997 and is significantly outdated and no
longer considered valid. The transit LOS analyses are therefore based on the 2010
Transfort Strategic Plan. The analysis is based on 4 factors —hours of weekday service,

A. Pedestrian Level of Service
The project area was evaluated for compliance with the pedestrian level of service
standards. Currently, the site does not meet the required standards of the City.
Sidewalks along College Avenue are attached and only 4-feet wide and the sidewalks
along Prospect are attached. The project will improve sidewalk conditions adjacent to
the project. The results of the analysis reveal that the project is in compliance with the
standards and are displayed in the figure below. The following is a review of the
evaluation. LOS worksheets are provided in Appendix G.
Directness — The project is adjacent to the Mason Street Corridor that will allow
direct pedestrian access to CSU to the north and shopping opportunities to the
south. To the north, there are sidewalks adjacent to the existing commercial
structures that make the direct connection to the Mason Corridor Prospect Station
viable.
Continuity — The area is surrounded by well used sidewalks, albeit not up to
standards. There is a lack of continuity currently on the west side of College
Avenue at Rutgers. However, with a connection to the trail, continuity will be
achieved. There is currently a short worn path at the south end of the project that
connects to the Spring Creek Trail which would in turn connect to the Mason
Corridor. It is recommended that this short portion of path be paved.
Street Crossings — The intersection of Prospect/College is traffic signal
controlled with pedestrian phases. There are five lanes to cross the north -south
direction with well -marked crosswalks. There will be a mid- k/signalized
crossing of Prospect for the Mason Corridor project by the Year 2010. 201

Visual Interest and Amenity — The project is located in an older area of the city
that has suffered "visual deterioration' over the years. Although the project will

VIII. Multi -Modal Evaluation
Section 4.5.3 (B) of the Larimer County Urban Area Street Standards requires that
projects undergo a level of service analysis for alternative modes of transportation. The
modes of transportation that must meet LOS standards are bicycles, and pedestrians.
Transit service LOS must also be analyzed at the time of development review.
However, transit LOS is not part of the Adequate Public Facilities test. The area of
interest for the alternative modes of transportation is shown below in Figure 9. It is
likely that the project will generate numerous transit trips, bicycle and pedestrian trips
and it is therefore important that the alternative mode system be adequate to serve this
need. The area of the project is considered a "Commercial Corridor" based on the City
Structure Plan and for purposes of these analyses.

VII. Improvements
A. Traffic Signals
Traffic signals are never installed until Warrant is satisfied under the Manual on
Uniform Traffic Control Devices, 2000. During the course of a preparing a
transportation study, Warrant #3, the Peak Hour Warrant, is usually the best indication
of a whether or not a traffic signal will be needed in the future. Based on a review of the
two STOP sign controlled intersections, no new traffic signals will be required with this
project.
B. Auxiliary Lanes
A review of the LUCASS and the SIIAC requirements regarding auxiliary lanes was
undertaken as part of this study. The two intersections in question are the site access off
of College Avenue and the SB right turn at College and Stuart. Based on the review, the
projected turning movements for both the short and long range do not meet the
thresholds for requiring right turn lanes.
The intersection of College and parker needs to be reconstructed to limit turning
movements to'/4 intersection. Storage for the north and southbound turning movements
are as follows:
- southbound left turn — 100 feet
northbound left turn — 120 feet
In addition, in the long range future, the City should considering medians in Prospect
Road to limit the left turns at the northern access. There is approximately 270 feet
between College Avenue and the northern access. The will be queuing problems that
between the conflicting left turns at these two intersections. These issues will certainly
affect the through movements during the peak hours.

VI. Traffic Analysis
Capacity analysis was performed at the key intersections for both the background traffic
as well as the total traffic for the year 2010. The year 2028 total traffic was also
modeled and analyzed as part of this study. The analyses followed the procedures of the
Highway Capacity Manual 2000. Table 4, 5 and 6 display the results of the analyses.
As can be seen in Table 4 (2010 background), the intersection of Parker/College exhibits
failing movements. The NB left turn at the northern access and Propspect Road also is
at LOS F. All other key intersections continue to operate at acceptable levels of service
in the short term background traffic.
In Table 5, short-term total traffic, the intersection of College/Parker has been modified
to a 3/4 movement intersection whereby improving LOS for the intersection as well as
increasing the safety of the intersection. All key intersections operate at acceptable LOS
in the short-term build alternative.
The long term projections result in significant capacity issues with the intersection of
Prospect/College. Several movements as well as the overall LOS falls into the LOS F
category. This is an issue that the City has been aware of for quite some time. There
will need to be significant improvements through a capital project at this intersection to
improve the capacity and traffic flow. Additionally, the NB left turn at the intersection
of College/Parker falls into the LOS F category. However, this is acceptable and normal
for an urban condition. The NB left turn at the intersection of Prospect/northern access
will be difficult and have failing LOS in the future. It should be noted, the APF
requirements for LOS only apply to the short term and not the long-range projections.
The failure of the long-term condition at the intersection is a direct result of growth in
background traffic after the year 2010.

V. Traffic Projections
Background traffic for the year 2010 was estimated by assuming that all traffic
movements on the public roadway system would increase by 1.5% per year, as agreed to
in the initial scoping meeting with the Traffic Operations Department. This traffic
projection is consistent with the recent history of traffic growth in the area as well as the
approved regional travel demand forecasting model. Background traffic is displayed in
Figure 6 on the following page.
Site -generated traffic was then added to the background traffic to determine the total
traffic volumes at the key intersections. Total traffic for the year 2010 is displayed in
Figure 7. As a note, the project will be constructed in two phases. Since the trip
generation of the first phase is relatively low, it was determined to assign of both phases
of the project to the short-term to generate a conservative analysis. Traffic at the
driveways was expected to remain fairly constant. The existing retail would be
eliminated and replaced with a similar amount of retail.
Traffic projections were also increased by 1.5% per year out to the year 2028. Total
traffic projections are displayed in Figure 8.

For a student housing project, it is normal to assume a trip reduction based due to high
pedestrian, bicycle, and transit usage. Due to the proximity of the Mason Corridor, it is
likely that the peak hour trip characteristics will be less than Table 3 displays but the
data below will allow for a conservative analysis.

C. Trip Distribution
Trip distribution is the process of determining where the trips are coming to and from the
site. The distribution was based on the sites proximity to CSU and to shopping
opportunities as well as engineering judgment. The distribution is expected to remain
fairly constant over the long term. The distribution for the project is displayed in Figure
4. Site distributed traffic is shown in Figure 5.

IV. Project Description
A. Project
The project is a mixed use redevelopment of the site on the northwest corner of College
Avenue and Stuart Street in Fort Collins, Colorado. The project consists of student
housing (approximately 1000 beds in 229 apartments) and approximately 41 thousand
square feet of specialty retail composed within 3 buildings. The site is adjacent to the
Mason Street Corridor and within close proximity to Colorado State University and will
offer excellent opportunities for residents to use alternative modes of transportation for
primary trip ends.
Access to the site will be via a curb cut on College Avenue, Stuart Street and Prospect
Road. The access on College Avenue aligns with Parker Street on the east and is
currently operating as a full -movement intersection. The plan with this project is to
modify the access on College to a'/4 movement which would allow the NB and SB left
turns but not allow the east and west left turns or through movements. The
modification of the intersection will improve LOS and safety at the intersection.

Q. Current Traffic Conditions
Capacity analyses were performed at the key intersections to determine if existing
deficiencies exist on the roadway network. The analyses followed the procedures of the
Highway Capacity Manual 2000. Level of Service (LOS) is a qualitative term
describing operating conditions and expressed in terms of delay. Table 1 below provides
the definitions of LOS for both signalized and unsignalized intersections. Table 2
displays the results of the analyses. The worksheets from the analyses can be found in
Appendix C.

As can be seen in Table 2, the key intersections are currently operating at acceptable
levels of service. The Parker/Site Access location is a STOP sign controlled intersection
and the minor roadway movements (EB and WB left turns and through movements) are
operating at LOS F. However, the approach delay is within acceptable levels and failing
left/thru movements at minor intersections along a major arterial is considered normal
for an urban condition.

III. Existing Conditions
A). Current Traffic
Recent peak hour turning movements at the key intersections were obtained during
March 2008 and access locations taken within the last year. The morning and afternoon
peak hour traffic counts at the key intersections are displayed in Figure 2. The peak hour
counts were conducted in 15 minute increments for the periods of 7:30-8:30 AM and
4:30-5:30 PM. The raw information regarding the turning movements is provided in
Appendix B.
B). Current Street System
College Avenue (US 287) is the principal north -south arterial that travels through Fort
Collins. College Avenue is a 6-lane arterial with auxiliary turn lanes where needed and
a speed limit of 40 mph. College Avenue is the most heavily traveled roadway within
the community and carries approximately 50,000 vehicles per day adjacent to the site.
The roadway is classified as an NR-B under the State Highway Access Code. The
intersections on College Avenue with Prospect and Stuart Street are signalized. There
are no bike lanes and bicycle travel is prohibited.
Prospect Road is the east -west arterial that borders the site to the north. There are no
bike lanes, pavement in reasonable to poor condition, with a two -way -left turn lane
(TWLTL). The speed limit in the vicinity of the project is 35 mph.
Stuart Street is a collector roadway with a speed limit of 25 mph. The roadway extends
approximately 200 feet west of College Avenue and ends at the Burlington Northern
Railroad tracks.

I. Introduction
This transportation impact study addresses the Choice Center Mixed Use project located
in Fort Collins, CO. The project is a student housing/retail project being proposed by
Capstone Development from Birmingham, Alabama. The site is located off of South
College Avenue just south of Prospect Road at the intersection of Spring Park. The site
is primarily vacant and is the property that was a mobile home park that was destroyed
during the flood of 1997. The remaining portions of the site are in an old strip mall that
will be redeveloped.
The project entails the construction of apartment units consisting of 1,2 and 3 bedrooms
(1000 bedrooms approximately) and three retail buildings. The project will be
constructed in 2 phases. Figure 1 on the following page is a vicinity map displaying the
location of the project.
II. Agency Discussions
Discussions with City staff indicated that an full traffic study as described in Chapter 4
of the Larimer County Urban Area Streets Standards (LCUASS) would be appropriate
for this particular development. Staff also requested that an alternative modes analysis
be conducted as part of the TIS. Although the peak hours for a student housing oriented
development are between 10:00AM and 3:OOPM, the City requested that standard peak
hours be used in the study.
There are no immediate or pending projects within the area to consider and background
traffic is assumed to be 1.5% per year. The short-range horizon for the project is the
year 2010 and the long range 2028. Appendix A contains the form (Attachment A),
which outlines the agreed to scope of the study
