I. IPITRODIJCTION
This intermediate transportation 'impact study (TIS) addresses the capacity,
geometric, and control requirements at and near the proposed Houska Automotive
Expansion; Houska Automotive is located in the south quadrant of the Riverside/Myrtle
intersection in Fort Collins, Colorado.
During the course of the analysis, numerous contacts were made with the project
planner (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" (LC.UASS). Appendix A
contains the Transportation Impact Study Base Assumptions form and related
attachments for the Houska Automotive Expansion. The study involved the following
steps: .
• Collect physical, traffic, and development data;
• Pertorm trip generation, trip distribution, and trip assignment;
• Determine peak hour traffc volumes;
• Conduct capacity and operational level of service analyses on key intersections;
� e Analyze signal warrants;
e Conduct level of service evaluation of pedestriah, bicycle, and fransit modes of
transportation,

II. EXISTING CONDITIOIdS
The location of the Houska Automotive Expansion 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 and residentiaL There are
residential uses to the west of the site. There are commercial uses to the north and south
of the site. The eenter of Fort Coflins lies to the west of the proposed Houska Automotive
� Expansion site. Land adjacent to the site is flat (<2% grade) from a traffic operations
perspective.
Roads
�
The primary streets near the Houska Automotive site are Riverside Avenue and
Lemay Avenue. The existing geometry at the key intersections is shown in Figure 2.
Riverside Avenue is adjacent to the proposed Houska Automotive Expansion
site. It is a northwest-southeasfi direction street elassified as a four-lane arterial
according to the Fort Collins Master Street plan. Currently, Riverside Avenue has a
four-lane cross section with no center median (left-turn) lane, except at arterial
intersections. At the Lemay/Riverside intersection, R.iverside Avenue has eastbound
and westbound left-turn lanes, two through lanes in each direction, and an easfbound
right-turn lane. The Lemay/Riverside intersection has signal control. The posted speed
limit in this area of Riverside Avenue is 35 mph.
Lemay Avenue is to the southeast of the proposed Houska Automotive
Expansion site. It is a north-south street class�ed as a four-lane arterial according to
the Fort Collins Master Street Plan. Currently, Lemay Avenue has a four-lane cross
section with a center median. At the Lemay/Riversitle intersection, Lemay Avenue has
northbound and southbound left-turn lanes, two through lanes in each direction, and a
northbound flared channelized right-turn lane. The flared ch2�nelized right-turn lane
begins approximately 60 feet south of the Lemay/Riverside intersection stop bar. The
posted speed Iimit in this area of Lemay Avenue is 35 mph.
Existing Traffic
Figure 3 shows recent peak hour traffic counts at the Lemay/Riverside
intersection. The traffic counts at the Lemay/Riverside intersection were obtained in
June 2013.by the City of Fort Collins. Raw traffic count data is provided in Appendix B.
New counts could not be performed due to bridge replacement construction on Mulberry
Street, which affects the traffie pattern at many intersections in the area. Therefore, the

traffic volumes at the Lemay/Riverside intersection were factored to reflect a year 2015
condition. Figure 4 shows the factored recent peak hour traffic at the Lemay/Riverside,
Riverside/Access A, and Riverside/Access B intersections. The trafFc volumes at the
Riverside/Access A and Riverside/Access B in#ersections were synthesized based upon
the land use of Automobile Care Center (Code 942).
Existing Operation
The Lemay/Riverside, Riverside/Access A, and Riverside/Aceess B intersections
were evaluated using techniques provided in the 2010 Hiqhwav _Capaciiv Manual.
Calculation forms are provided in Appendix C. Using the morning and aftemoon peak
hour traffic shown in Figure 4, the peak hour operation and the calculated delay for
levels of service E are shown in Table 1. A description of level of service for signalized
and unsignalized intersections from the 2010 Hiqhway Gapacity IVlanual is provided in
Appendix C. Table 4-3 (revised per staff comments regarding type of intersection)
showing the Fort Collins IVlotor Vehicle LOS Standards (Intersections) are also provided
in Appendix C. This site is in an area termed "Commercial Corridor" on the Fort Collins
Structuce Plan. In areas termed "Commercial Corridor," aeceptable overall operation at
signalized interseetions 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 all stop sign controlled intersections, there is no level of serviee standard.
The key intersections currently meet the City of Fort Collins Motor Vehicle LOS
Standard during in the morning and afternoon peak hours.
Pedestrian Facilities
There are sidewalks along the south side of Riverside Avenue adjacent to
developed properties. There are sidewalks along both sides of Lemay Avenue. It is
expec#ed that as properties in this area are developed or redeveloped, sidewalks will be
installed as part of the street/property infcastructure.
Bicycle Facilities
Bicycle lanes exist along Lemay Avenue wifhin the study area. The Fort Collins
Bike Map shows no bicycle related designations for Riverside Ayenue,
Transit Facilities
Currently, this area of Fort Collins is served by Transfort route 5 along Lemay
Avenue.

191. PROPOSED DEVELOPMENT
The Houska Automotive Expansion is a proposed commercial (auto/truck related)
de�elopment. Figure 5 shows a site plan of the Houska Automotive Expansion; The
Houska Rutomotive Expansion is proposed as an approximately 34,000 square foot
major automobile repair facility in two buildings. Primary access to Houska Automotive
Expansion will be via a full-movement access toffrom Riverside Avenue. There are finro
existing accesses to Houska Automotive. The existing south access to the property will
be vacated and a new access (Access B) will be constructed approximately 80 feet
south of the existing access. The short ran.ge analysis (Year 2020) mcludes
development of the Houska Automotive Expansion site and an appropriate increase in
background traffic, due to normal growth, and other approved or expected
developments in the area.
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. 9t" Edition, ITE was used to estimate the trips that would be
generated by the proposed/expected uses at the Houska Automotive site. A trip is defined
� as a one-way vehicle movement from origin to destination; Table 2 shows the dail and
Y
' peak hour trip generation for the Houska Automotive Expansion. Full developmer�� of
Houska Automotive Expansion resulted in 644 daily weekday trip ends, 77 morning
peak hour trip ends, and 106 afternoon peak hour trip ends. It is important to note that
this project was originally scoped using different land uses and trip generation. The #rip
�generation shown in Table 2 is higher than what is shown in the scoping packet in
, Appendix A.
Trip Distribution
Trip distribution for the Houska Automotive Expansion 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 (2020) analysis future. The trip distribution was agreed to by City of Fort Collins
staff in the scoping discussions.

Background Tra�c Projections
Figure 7 shows the short range (2020) background peak hour trafFc projections.
These foreeasts assume that the current street network exists in this area. Background
#ra#fic projections for the short range were obtained by reviewing the North Front Range
Regional Transportation Plan, engineering judgment, and various traffic studies
prepared for this area of Fort Collins. Based upon these sources, it was determined
that the traffic volumes would increase by approximately 1_0 percent per year.
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 frip distribution
process. Using the trip distribution shown in Figure 6, 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 de#ermine the total forecasted vehicle traffic at
the key intersections. Figure 9 shows the short range (2020) total peak hour vehicle
traffic at the key intersections.
Signal Warrants
��

�'.

�
��.
�
t
�
.
�
�
�
�:
��
As a matter of policy, traffic signals are not installed at any location unless warrants
are met accordi.ng to the Manual on Un�orm Traffic Control Devices� For the streets in the
vicinity of the Houska Automotive Expansion development, four hour and/or eight hour
signal warrants are applieable. These warrants require much data and are applied when
the traffic is actually on the area street system. It is acknowledged that peak hour signal
ararrants should not be applied, but since the peak hour forecasts are readily ava_ilable in a
traffic impact study, it is reasonable to use them to get an idea whether other signal
warrants may be met. If peak hour signal warrants will not be met at a gi�en intersection,
it is reasonable to condude that it is not likely that other signal warrants would be met. If
peak hour signal warrants are met, it merely indicates that further evaluation should occur
in the future as the development occurs. However, a judgment can be made that some
intersecfions will likely meet other signal warrants. The Lemay/Riverside intersectior� is
eurrently signalized. Signals will not be warranted at the site access intersections.
Geometry
Figure 10 shows a sehematic of the short range (2020) geometry. Since Riverside
�. Avenue is an arterial street, a center median (left-turn lanes) lane is required on Riverside
Avenue. These left-tum lanes are required with the current traffic volumes. There is
adequate width in the cross seation of Riverside Avenue to provide two through lanes in
eaeh direction and a center median lane. However, bicycle lanes cannot be striped and
bikes will need to share the street with motor vehicles. According to LCUASS, Figure 8-4,
eastbound right-tum lanes are not required at AccessA and Access B.

Operation Analysis
Operation analyses were performed at the key infersections. The operation
analyses were conducted for the short range analysis, reflecting a year 2020 condition.
In the intersection operation tables, the calculated delay for each movement�leg is
provided when the level of service falls in the LOS E/F categories.
Using the short range (2020) background peak hour traffic volumes, the key
interse�tions operate as indicated in Table 3. Calculation forms for these analyses are
provided in Appendix D. The key intersections operate acceptably wi#h existing control
in the morning and aftemoon peak hours. It is assumed that a center median lane (left
turn lane) will be striped on Riverside Avenue by/before the short range (2020) fufure.
Using the traffic volumes shown in Figure 9, the key intersections operate in the
.
short range (2020) total condition as indicated in Table 4. Calculation forms for these
analyses are provided in Appendix E. The key intersections operate similar to the
background operation with existing control and recommended geometry in the moming
and afternoon peak hours.
Pedestrian Level of Service
Appendix F shows a map of the area that is within 1320 feet of the Houska
Automotive Expansion development. There are three pedestrian destinations within
1320 feet of the Houska Automotive Expansion development, These are: 1) the
residential area to the west of this site; 2) the commercial uses to the south; and 3) the
Poudre River TraiL The Houska Automotive Expansion site is located within an area
termed as "all other areas," which sets the level of service threshold at LOS C for all
measured categories. Pedestrian level of service is achieved for all measured
aategories. The Pedestrian LOS Worksheet is provided in Appendix F.
Bicycle Level of Service
The Fort Collins Bike Map shows no bicycle related designations for Riverside
Avenue. Due to its width, bike lanes are not practical on Riverside Avenue.
Transit Level of Service
This area of Fort Collins is served by Transfort Route 5 along Lemay Avenue.

IV. CONCLUSIOIVS/RECOMiIAENDATIO1dS
This study assessed the impacts of fhe Houska Automotive Expansion
development on the short range (2020) street system in the vicinity of the proposed
development. As a result of this analysis, the following is concluded:
• The development of the Houska Automotive Expansion is feasible from a traffic
engineering standpoint. At full development, the Houska Automofive Expansion
site will generate approximately 644 daily weekday #rip ends, 77 morning peak
hour trip ends, and 106 afternoon peak hour trip ends.
• Current operation at the key intersections is acceptable with existing control and
geometry. ,
• In the short range (2020) future, given development of the Houska Automotive
Expansion and an increase in background traffic, the key intersections will meet the
Ciiy of Fort Collins Motor Vehicle LOS Standard.
• Acceptable level of seryice is achieved for pedestrian, bicycle, and transit modes
based upon the measures in the multi-modal transportation guidelines.
