I. INTRODUCTION
This transportation impact study (TIS) addresses the capacity, geometric, and
control requirements at and near the proposed Union on Elizabeth. The proposed Union
on Elizabeth site is located north of (adjacent to) West Elizabeth Street, between Shields
Street and City Park Avenue in Fort Collins, Colorado.
During the course of the analysis, numerous contacts were made with the project
developer (EDR), the project engineer (Northern Engineering), the project planning
consultant (Ripley Design), and the Fort Collins Traffic Engineering staff. This study
generally conforms to the format set forth in the Fort Collins transportation impact study
guidelines contained in the “Larimer County Urban Area Street Standards” (LCUASS).
The base assumptions packet is provided in Appendix A. 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.
This TIS is a revision of the “Union on Elizabeth Transportation Impact Study”
dated August 2017. It addresses City staff comments with regard to the access location
and a change in the number of units/beds.

II. EXISTING CONDITIONS
The location of the Union on Elizabeth site 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 institutional (CSU), commercial, or residential.
Land adjacent to the site is flat (<2% grade) from a traffic operations perspective. This site
is west of the center of Fort Collins. Colorado State University is east of the proposed
Union on Elizabeth site.
Roads
The primary streets near the Union on Elizabeth site are West Elizabeth Street,
Shields Street, and City Park Avenue. Figure 2 shows a schematic of the existing
geometry at the West Elizabeth/Shields and West Elizabeth/City Park intersections.
West Elizabeth Street is to the south (adjacent to) of the Union on Elizabeth site.
It is classified as a four-lane arterial street on the Fort Collins Master Street Plan.
Currently, West Elizabeth Street has a four-lane cross section in this area. At the West
Elizabeth/Shields intersection, West Elizabeth Street has eastbound and westbound
left-turn lanes, an eastbound left-turn/through lane, a westbound through lane, and
eastbound and westbound right-turn lanes. At the West Elizabeth/City Park
intersection, West Elizabeth Street has eastbound and westbound left-turn lanes and
two through lanes in each direction. Eastbound and westbound right-turn lanes are
required with the existing traffic volumes at the West Elizabeth/City Park intersection.
Typically with constrained conditions, when turn lanes are shown to be required based
on volumes, they are not built unless the operation at the subject intersection is
determined to be unacceptable. The West Elizabeth/Shields and West Elizabeth/City
Park intersections have signal control. The posted speed limit in this area of West
Elizabeth Street is 30 mph.
Shields Street is to the east of the Union on Elizabeth site. It is a north-south
street designated as a four-lane arterial street on the Fort Collins Master Street Plan.
Currently, it has a four-lane cross section in this area. At the West Elizabeth/Shields
intersection, Shields Street has northbound and southbound left-turn lanes, two through
lanes in each direction, and a southbound right-turn lane. According to LCUASS, a
northbound right-turn lane is required with the existing traffic volumes at the west
Elizabeth/Shields intersection. With regard to this right-turn lane, Shields Street is
considered to be in a constrained condition. The posted speed limit in this area of
Shields Street is 30 mph.

City Park Avenue is a north-south street designated as a collector street on the
Fort Collins Master Street Plan. Currently, City Park Avenue has a two-lane cross
section with parking on both sides of the street. At the West Elizabeth/City Park
intersection, City Park Avenue has northbound and southbound left-turn lanes and a
through/right-turn lane in each direction. According to LCUASS, a northbound right-turn
lane is required with the existing traffic volumes at the West Elizabeth/City Park
intersection. With regard to this right-turn lane, City Park Avenue is considered to be in
a constrained condition. The posted speed limit in this area of City Park Avenue is 25
mph.
Existing Traffic
Figure 3 shows the recent morning and afternoon peak hour traffic counts at the
West Elizabeth/Shields and West Elizabeth/City Park intersections. Recent count data
at the West Elizabeth/Shields and West Elizabeth/City Park intersections was obtained
in October 2016. Raw count data is provided in Appendix B. Newer counts were not
done since current construction of the pedestrian underpass under Shields Street
affects the traffic in this area.
Existing Operation
The West Elizabeth/Shields and West Elizabeth/City Park intersections were
evaluated using techniques provided in the 2010 Highway Capacity Manual
(2010HCM). Using the peak hour traffic shown in Figure 3, the peak hour operation is
shown in Table 1. The West Elizabeth/Shields and West Elizabeth/City Park
intersections meet the City of Fort Collins Motor Vehicle LOS Standard during the
morning and afternoon peak hours with existing signal control, geometry, and signal
timing except the West Elizabeth/Shields intersection in the afternoon peak hour. At the
West Elizabeth/Shields intersection, the calculated delay for the northbound left-turn
lane was commensurate with level of service F. The calculated delay associated with
level of service F operation is provided in Table 1. Calculation forms are provided in
Appendix C. 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.
The Union on Elizabeth is in an area termed “mixed-use district.” In areas termed
“mixed-use districts,” acceptable operation at signalized intersections during the peak
hours is defined as level of service E or better for the overall intersection, and level of
service E or better for any leg or movement. At arterial/arterial and collector/collector
stop sign controlled intersections, acceptable operation is considered to be at level of
service E, overall and level of service F, for any approach leg. At arterial/collector,
arterial/local, collector/local, and local/local stop sign controlled intersections,
acceptable operation is considered to be at level of service D, overall and level of
service F, for any approach leg.

It is important to note that, since the West Elizabeth/Shields intersection has an
eastbound left-turn lane, a shared eastbound left-turn/through lane and right-turn lane
on West Elizabeth Street, the signalized analysis, using the Synchro 2010HCM
software, has anomalies using this shared lane combination with large traffic volumes
on the shared lane. The anomalies have been recognized by the City of Fort Collins
Traffic Engineering staff, also. The high volumes occur only in the afternoon peak hour
at the West Elizabeth/Street intersection. These anomalies have not been seen using
the HCS 2010 HCM software. Therefore, the West Elizabeth/Shields intersection
afternoon peak hour was analyzed using the HCS 2010 HCM software in the existing
analysis.
Pedestrian Facilities
There are sidewalks along West Elizabeth Street, Shields Street, and City Park
Avenue.
Bicycle Facilities
Bicycle lanes exist on West Elizabeth Street and Shields Street. City Park
Avenue has no bicycle lanes. Bike lanes are not required on local streets.
Transit Facilities
This area of Fort Collins is served by Transfort Route 2 on West Elizabeth Street,
Routes 3, 31 and 32 on Plum Street, and Routes 7 and 19 on Shields Street.

III. PROPOSED DEVELOPMENT
The Union on Elizabeth development is a student residential development with
402 beds (105 apartment dwelling units) and 3,875 square feet of retail. Figure 4 shows
a site plan of the Union on Elizabeth development. The site plan shows access to/from
West Elizabeth Street. There will be no motor vehicle access to Plum Street. There will
be pedestrian and bicycle access to Plum Street. The Union on Elizabeth development
will replace the St Paul’s Episcopal Church and Campus West Shops. The short range
analysis (Year 2022) includes development of the Union on Elizabeth site and an
appropriate increase in background traffic, due to normal growth, and other approved
developments in the area. The long range analysis (Year 2035) includes background
traffic due to normal growth and in general accordance with the Fort Collins Structure
Plan.
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, 9th Edition, ITE is customarily used to estimate trips that
would be generated by the proposed/expected use at a site. However, the City of Fort
Collins has developed trip generation rates for apartment projects similar to Union on
Elizabeth. The Fort Collins trip generation rates are specifically applied to student housing
projects. Table 2 shows the daily and peak hour trip generation for the Union on Elizabeth
site. It is assumed that alternative modes (pedestrian, bicycle, and transit) have been
considered in the City of Fort Collins rates for apartments. The trip generation of the
Union on Elizabeth development resulted in 1238 daily trip ends, 81 morning peak hour
trip ends, and 180 afternoon peak hour trip ends.

Trip Distribution
Directional distribution of the generated trips was determined for the Union on
Elizabeth site. Figure 5 shows the vehicle trip distribution used for the Union on Elizabeth
site. The trip distribution was agreed to by City of Fort Collins staff in the scoping
discussions.
Background Traffic Projections
Figures 6 and 7 show the short range (2022) and long range (2035) background
peak hour traffic projections at the key intersections. Traffic at the key intersections was
increased at a rate of approximately one percent per year for the short range (2022) and
long range (2035) background traffic forecasts. In addition to this, site generated traffic
from the Kapoor, the Hub, and West Plum Street Apartment developments were
included in the traffic forecasts. Site generated traffic from St. Paul‘s Episcopal Church
and Campus West Shops were excluded from the traffic forecasts since they will be
razed for the Union on Elizabeth development.
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. Using the trip distribution shown in Figure 5, Figure 8 shows the assignment
of the site generated peak hour vehicle traffic. The site generated vehicle traffic was
combined with the background traffic to determine the total forecasted vehicle traffic at
the key intersections. Figures 9 and 10 shows the short range (2022) and long range
(2035) total peak hour vehicle traffic at the key intersections. The long range
background and total hour traffic forecasts (Figures 7 and 10) are generally higher than
those reflected in the “West Elizabeth Corridor Plan” at the West Elizabeth/Shields and
West Elizabeth/City Park intersections. The forecasts in this TIS consider
known/approved development projects.
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 (MUTCD). The West
Elizabeth/Shields and West Elizabeth/City Park intersections are currently signalized.
The stop sign controlled intersection at the West Elizabeth/Site Access intersection is not
expected to meet peak hour signal warrants and does not meet signal spacing
requirements.

Operation Analysis
Operation analyses were performed at the West Elizabeth/Shields, West
Elizabeth/City Park, and West Elizabeth/Site Access intersections. The operation
analyses were conducted for the short range future, reflecting a year 2022 condition and
for the long range future, reflecting a year 2035 condition. The long range (2035)
operational analyses are used for planning and informational purposes only.
Using the short range (2022) background peak hour traffic volumes, the West
Elizabeth/Shields and West Elizabeth/City Park intersections operate as indicated in
Table 3. Calculation forms for these analyses are provided in Appendix D. The key
intersections will meet the City of Fort Collins Motor Vehicle LOS Standard in the
morning and afternoon peak hours, except the northbound left-turn movement at the
West Elizabeth/Shields intersection in the afternoon peak hour.
Using the long range (2035) background peak hour traffic volumes, the West
Elizabeth/Shields and West Elizabeth/City Park intersections operate as indicated in
Table 4. Calculation forms for these analyses are provided in Appendix E. In the long
range (2035) future, the West Elizabeth/Shields intersection does not meet the City of
Fort Collins Motor Vehicle LOS standard in the afternoon peak hour. It is important for
the City of Fort Collins to continue monitoring traffic conditions at this intersection in the
future to determine if and when any additional improvements are needed.
Using the short range (2022) total peak hour traffic volumes, the West
Elizabeth/Shields, West Elizabeth/City Park, and West Elizabeth/Site Access
intersections operate as indicated in Table 5. Calculation forms for these analyses are
provided in Appendix F. The key intersections will meet the City of Fort Collins Motor
Vehicle LOS Standard in the morning and afternoon peak hours, except the northbound
left-turn movement at the West Elizabeth/Shields intersection in the afternoon peak
hour.
Using the long range (2035) total peak hour traffic volumes, the West
Elizabeth/Shields, West Elizabeth/City Park, and West Elizabeth/Site Access
intersections operate as indicated in Table 6. Calculation forms for these analyses are
provided in Appendix G. In the long range (2035) future, the West Elizabeth/Shields
intersection does not meet the City of fort Collins Motor Vehicle LOS standard in the
afternoon peak hour. It is important for the City of Fort Collins to continue monitoring
traffic conditions at this intersection in the future to determine if and when any additional
improvements are needed.
Geometry
The short range (2022) and long range (2035) geometry is shown in Figure 11. As
mentioned earlier, according to LCUASS, a northbound right-turn lane at the West
Elizabeth/Shields intersection and eastbound and westbound right-turn lanes at the

to be unacceptable. Also a westbound right-turn lane at West Elizabeth/Site Access
intersection is required.
Pedestrian Level of Service
Appendix H shows a map of the area that is within 1320 feet of the Union on
Elizabeth site. The Union on Elizabeth site is located within an area termed as a
“pedestrian district,” which sets the level of service threshold at LOS A for all measured
categories, except for street crossing at LOS B. There are four destination areas within
1320 feet of the proposed Union on Elizabeth: 1) the Colorado State University
Campus; 2) the commercial/residential to the south of the site; 3) the
commercial/residential to the west of the site; and 4) the residential uses to the north the
site. The Pedestrian LOS Worksheet is provided in Appendix H. The pedestrian
destination areas meet the LOS requirements for all categories.
Bicycle Level of Service
Appendix H shows a map of the area that is within 1320 feet of the Union on
Elizabeth site. This area is considered to be a community/neighborhood commercial
center. Based upon Fort Collins bicycle LOS criteria, the level of service threshold for
bicycles is LOS B. There are two bicycle destinations within 1320 feet of the Union on
Elizabeth. These are: 1) Colorado State University to the east of the site; and 2) the
commercial center around the site. There are bicycle facilities along West Elizabeth
Street, Plum Street, and Shields Street. The Union on Elizabeth is directly connected to
the bike lanes on West Elizabeth Street and Shields Street, which satisfies the LOS A
criteria. The bicycle LOS Worksheet is provided in Appendix H.
Transit Level of Service
This area of Fort Collins will be served by Transfort Routes 7 and 19 on Shields
Street, Routes 2 on West Elizabeth Street, and Routes 3, 31, 32 on Plum Street.
According to Transfort, the West Elizabeth Street and Plum Street routes have very high
ridership. Route 3 has headways every 15 minutes when CSU is in session and every
30 minutes when CSU is out of session. Route 31 has headways every 10 minutes
when CSU is in session and does not operate when CSU is out of session. Route 32
has headways every 30 minutes when CSU is in session and does not operate when
CSU is out of sessions. Route 2 has headways every 30 minutes. These routes have
an effective headway of 4-5 minutes in this area.

Mitigation
A northbound right-turn lane is required at the West Elizabeth/Shields
intersection. The Union on Elizabeth adds no traffic to the northbound right-turn
movement. Eastbound and westbound right-turn lanes are required at the West
Elizabeth/City Park intersection with existing traffic. The Union on Elizabeth adds no
traffic to the eastbound right-turn movement. In the short range (2022) future, the Union
on Elizabeth adds 6 percent to the morning peak hour and 4 percent to the afternoon
peak hour westbound right-turn movement. Although the project does not add
significant traffic to the westbound right-turn movement, the following mitigation factors
will be implemented:
Residents (students) have Transfort passes that provide access to all Transfort
fixed-routes including MAX and FLEX. The Union on Elizabeth will inform
students regarding this benefit and promote it by making transit maps readily
available in the leasing office and hosting educational programs.
Six hundred and twelve bicycle spaces will be provided within the development.
Eighty bicycle spaces are uncovered, seventy five bicycle spaces are covered,
and there are fifty five located within a bike storage room within the parking
garage. There will be four hundred and two wall mounted bicycle racks/hooks,
one per bedroom, located within the apartment units. In addition, there will be a
bike rack for the City wide bike share program. Secure bicycle parking and the
bike share program will encourage residents to utilize bicycles as a mode of
travel.
An enhanced pedestrian/bicycle corridor running north/south will connect to the
Lokal property to the north. This will allow pedestrians and bicyclist from the north
to access the HAWK signal and the Shields Street underpass.

IV. CONCLUSIONS/RECOMMENDATIONS
This study assessed the impacts of the Union on Elizabeth development on the
short range (2022) and long range (2035) street system in the vicinity of the proposed
development. As a result of this analysis, the following is concluded:
The development of the Union on Elizabeth site is feasible from a traffic
engineering standpoint. At full development, the Union on Elizabeth site will
generate approximately 1238 daily trip ends, 81 morning peak hour trip ends,
and 180 afternoon peak hour trip ends.
Current operation at the West Elizabeth/Shields, West Elizabeth/City Park, and
West Elizabeth/Site Access intersections is acceptable, except the West
Elizabeth/Shields intersection in the afternoon peak hour. At the West
Elizabeth/Shields intersection, the calculated delay for the northbound left-turn
lane was commensurate with level of service F.
In the short range (2022) future, given development of the Union on Elizabeth
site and an increase in background traffic, the West Elizabeth/Shields, West
Elizabeth/City Park, and West Elizabeth/Site Access intersections will meet the
City of Fort Collins Motor Vehicle LOS Standard in the morning and afternoon
peak hours, except the northbound left-turn movement at the West
Elizabeth/Shields intersection in the afternoon peak hour.
In the long range (2035) future, given development of the Union on Elizabeth site
and an increase in background traffic, the key intersections will meet the City of
Fort Collins Motor Vehicle LOS Standard in the morning and afternoon peak
hours, except at the West Elizabeth/Shields intersection in the afternoon peak
hour. The long range (2035) operational analyses are used for planning and
informational purposes only.
The short range (2022) and long range (2035) geometry is shown in Figure 11. A
northbound right-turn lane at the West Elizabeth/Shields intersection and
eastbound and westbound right-turn lanes at the West Elizabeth/City Park
intersection are required with the existing traffic volumes. West Elizabeth/City
Park intersections meet the City of Fort Collins Motor Vehicle LOS Standard without
the required right-turn lanes. Union on Elizabeth added no traffic to the northbound
right-turn lane at the West Elizabeth/Shields intersection.
Acceptable level of service is achieved for pedestrian, bicycles, and transit based
upon the measures in the multi-modal transportation guidelines.
