1.0 Introduction
This transportation impact study addresses the Vineyard-Goldelm ODP/PDP located on
the west side of College Avenue (US287) between Crestridge Road and Fossil Creek
Boulevard in Fort Collins, Colorado. The site has sat vacant for years and numerous
proposals have been submitted for this site. The site should be considered an infill
development since it is surrounded by older county developments. The project will be
constructed in phases and includes 250 apartments (non-student), a 42,000 square foot
church, and either 18,000 square feet of car sales or specialty retail. For analysis
purposes, the project will be built in three phases.
Figure 1 on the following page is a vicinity map displaying the location of the project.
2.0 Agency Discussions
Initial discussions with City staff indicated that a Full Transportation Impact Study as
described in Chapter 4 of the Larimer County Urban Area Streets Standards (LCUASS)
would be appropriate for this particular development.
The project is considered infill and redevelopment and there are no recently approved
projects in the area that need to be considered in the analysis. College Avenue recently
has been repaved with minor improvements to the intersection of Skyway and College.
College Avenue is a State Highway (US287) and has an Access Control Plan in place.
The study will address the existing condition, a 2-year horizon, a 4-year horizon and a
20-year horizon for planning purposes. Traffic projections for College Avenue are from
the Colorado Department of Transportation.
Appendix A contains the form (Attachment A), which outlines the agreed to scope of
work for the study.

3.0 Existing Conditions
3.1. Current Traffic
Peak hour turning movements for the College/Crestridge, College/Smokey, and the
College/Skyway were obtained in January 2016. Counts at these three locations were
taken in 2-hour blocks of time in 15-minute increments. The counts were taken in the
AM between 7:00-9:00 and in the PM between 4:00-6:00. The data was collected in
between the snowstorms of January when traffic was fairly normalized. The raw data
regarding the turning movements is provided in Appendix B.
3.2 Current Street System
The project is located in south Fort Collins on the west side of College Avenue between
Crestridge and Fossil Creek Boulevard. The project intends to align Crestridge with
Smokey on the east for full movement access with a potential traffic signal. Additional
access is proposed on the north end of the project with a limited (RI/RO) movement.
The land uses in the area are mixed
with commercial and residential.
All the developments in the south
and to the east of the site were built
under older County standards. To
the north of the site is the Redtail
Grove Natural Area owned by the
City of Fort Collins.
College Avenue is the main north-
south thoroughfare in Fort Collins
and is also US 287. The roadway is
under the jurisdiction of the
Colorado Department of
Transportation (CDOT). College

Avenue is classified as an NRA Highway and currently has an Access Control Plan
(ACP) in place that governs future access. College Avenue is a four-lane highway with
a center left turn lane, shoulders and auxiliary lanes at intersections where needed. The
speed limit is posted 55 mph and the pavement is in good condition.
Crestridge is a collector roadway
that will provide full-access to the
proposed development. The
roadway connects to Venus Street
and provides access to the
residential area to the south as well
as the car dealership. The roadway
appears to be used more for
parking than access and is in poor
condition.
Smokey Street is a substandard
roadway that provides access to
an industrial area to the east of
College Avenue. The roadway is
in poor condition; no sidewalk,
curb or gutter, and in a state of
disrepair.

The intersection of College Ave and
Skyway is controlled under a 6-phase
traffic signal. Skyway traffic
movements are relatively minor and
the roadway provides access to the
neighborhoods on both the east and
west side of College Avenue. The
radii on Skyway are non-existent and
traffic operations for the turning
movements is hindered by the poor
geometry.
3.3 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 2010. For the intersections of College/Crestridge and
College/Smokey, it was observed that most folks making the left turn maneuver from the
side street were using the TWLTL as a refuge. The intersections were model/analyzed
as a two-stage left turn. Observation at the intersection also revealed that although there
are no north or southbound left turn lanes at Crestridge or Smokey, the shoulders act as
right turn lanes.
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.
All key intersections operate at acceptable levels of service. The worksheets from the
analyses can be found in Appendix C.

experiencing delay – primarily the left turns onto College Avenue. This is a normal
condition for an urban area.
A Traffic Signal Warrant Analysis was conducted for the existing condition to determine
if signalization was warranted at this time. The results indicate that the intersection of
Crestridge/College/Smokey did not meet signal warrants under today’s trafficand the
MUTCD requirements. Only the Peak Hour Warrant (#3) was analyzed. Results of this
analysis is found in Appendix D.
4.0 Project Description
4.1 Project
The project consists of developing the vacant parcel of land on the west side of College
Avenue between Crestridge Road and Fossil Creek Boulevard. The property is situated
just south of the Redtail Grove Natural Area. The project proposes to construct the
project in three phases:
Phase I – 250 apartments (non-student)
Phase II – 18 thousand square feet of either specialty retail or auto sales
Phase III – 42 thousand square feet for the Vineyard church
The project is surrounded by both commercial and residential developments. Access to
the site will be from a right-in/right-out access on the north end of the project and on the
south, at Crestridge Road. Crestridge Road is anticipated to be signalized in the future
and realigned with Smokey Street on the east side of College Avenue.
For analysis purposes, it will be assumed that the development will be completed in the
following years:
Phase I by 2018
Phase II by 2020
Phase III is undetermined but will be considered in the long term analysis.
The preliminary site plan is displayed in Figure 3.

4.2 Trip Generation
Trip generation rates for the proposed project are based on the ITE Trip Generation, 9
th
Edition. The manual presents data from numerous trip generation studies for a variety of
land uses from across the country. ITE Code 220, Apartments, was used for the
residential and ITE Code 826 for the retail portion, and ITE Code 560 for the church use.
No trip reductions were assumed as part of the project.
Table 3 below summarizes the proposed trip generation for the project. For the entire
project, during the morning peak hour, 294 trip ends can be expected and 298 trip ends
can be expected from the project during the afternoon peak hours.

4.3 Trip Distribution
Trip distribution is the process of determining where the trips are coming to and from the
site. Since all trips into the site must come enter the site from College Avenue, the
distribution is all north-south movements. The distribution for the project is displayed in
Figure 4.

4.4 Site Distributed Traffic
Based on the trip generation, the project trips were then assigned to the surrounding
roadway network based on the estimated trip distribution. The numbers have been
rounded to the nearest “5”. These estimated project trips will be utilized by adding them
to the background traffic then analyzed to estimated roadway impact. Site distributed
traffic is shown below in Figure 5.

5.0 Traffic Projections/Background Analysis
5.1 Traffic Projections
Background traffic for the horizon years was estimated by assuming that all traffic
movements would increase by 1.0% per year, as agreed to in the initial scoping meeting
with the Traffic Operations Department. The projections are based on the Colorado
Department of Transportation estimates and the OTIS estimation for future traffic
projections on the state highway system. Background traffic is displayed in Figure 6, 7
and 8.

5.2 Capacity Analysis - Background
Capacity analysis was performed for all the key intersections based on the techniques of
the 2010 Highway Capacity Manual. The analysis revealed that the intersection get
slightly worse in terms of delay as we moved through the horizon years. In particular,
the minor street left turns from Crestridge and Smokey experience high levels of delay
under stop sign control. The intersection of College/Skyway continues to operate at
good levels of service without improvements through the year 2036.
Tables 4-6 display the results of the analysis and capacity worksheets can be found in
Appendix E.

5.2 Total Traffic Projections and Analysis
Site generated traffic was then added to the background traffic to derive the total traffic
expected on the network for the horizons years. Figures 9-11 display the total traffic that
is used in the analysis.
While calculating the “Total Traffic Projections”, a Warrant Study was conducted at the
intersections of College Ave/Crestridge/Smokey. It was determined that with the first
phase of the project completed, the intersection would meet traffic signal warrants under
the Manual on Uniform Traffic Control Devices, 2009. For analysis purposes, it was
assumed that Crestridge and Smokey would be realigned sometime in between the
construction of phase I and phase II. However, this does not prohibit the developer to
construct the realignment during the phase I construction (which would be preferred on
several levels). The Year 2018 “Total Traffic” diagram as shown in Figure 9 assumed
that 65 EB left turn morning peak hour trips and 45 EB left turn morning trips went
south through the neighborhood to make the EBLT at Skyway and College. The delays
in making this movement at Crestridge would be severe and they would most likely cut
through the neighborhood to make the left turn safely.
From a daily trip perspective, ELB Engineering, LLC has estimated that the total project
would generate over 2800 trips per day. Half of these trips ends are in and the other half
are leaving the site. If the assumption is that 65% of these trips are heading north, there
will probably be 900 extra trips going through the neighborhood to make the left turn at
Skyway. From a traffic engineering perspective, going through the neighborhood is a
safe and reasonable maneuver. From a neighborhood perspective, the increase in traffic
will be unacceptable. If this project is to be successful, then the developer needs to find
a way to reconstruct Crestridge Road and signalize the intersection in the early stages of
the project.
The Warrant Study can be found in Appendix F and the Capacity Worksheets in
Appendix G.

Capacity analysis was performed on each of the key intersections for the years 2018,
2020 and for 2036. As stated earlier, it was assumed that in 2018, Crestridge and not yet
been realigned. The intersection of College and Skyway functioned well with additional
WB left turns added to the intersection.
In the years 2020 and 2036, it was assumed that the key intersection had been realigned.
For analysis purposes the following geometry was assumed:
The NB and SB approaches all had left turn lanes, two through lanes and an
auxiliary right turn lane.
Crestridge approach assumed a left turn lane and a combination thru-right
The Smokey approach assumed the existing geometry with a combination left-
thru-right.
The intersection operated under a 6-phase traffic signal with protected/permitted
left turn phasing for the north and southbound left turns.
The results of the analysis are shown in Tables 7-9 on the following pages. The key
intersections operate under acceptable conditions in the short and long range future.

6.0 Improvements
6.1. Auxiliary Lanes:
College Avenue is a State Highway under the “NRA” classification category with a
speed limit of 55 mph. Based on the State Highway Access Code, the following
improvements would be required:
Connection of Venus at College Ave.:
o Southbound deceleration lane of 600’. This may be difficult to
accomplish with the bridge in place over Fossil Creek
o A southbound acceleration lane from Venus at a length of 960’
o Some form of median control to prevent the NB left turn and the and the
EB left turn from the intersection

College/Smokey/Crestridge Realignment
o NB and SB right turn lanes should be provided at the new intersection
with at least 600’ of deceleration and 60 ‘ of storage.
o NB and SB right turn lanes are already present and should be brought up
to the code in terms of deceleration.
o NB and SB acceleration lanes would be required at the intersection that
would accommodate “free right turns”
7.0. 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.
7.1 Pedestrian Level of Service
The project area was evaluated for compliance with the pedestrian level of service
standards. The project will construct pedestrian facilities an amenities to ensure that on-
site pedestrian is safe and pleasant. Sidewalks, crosswalks, appropriate lighting will all
be in place as the project develops.
As stated previously, the site is surrounded by older county developments and there are
no sidewalks in the immediate vicinity. It is physically impossible to connect to exist to
surrounding neighborhoods via pedestrian facilities.
There are sidewalks in the Redtail Ponds development to the north of the site but there
isn’t an area considered a “pedestrian destination” in the development.
On the northeast corner of the site, a pedestrian/trail connection could be made to the
Mason Street Trail that would give additional access to other locations.
The development will provide all pedestrian facilities and amenities in conformance with
the City of Fort Collins standards.
7.2 Bicycles Level of Service
The project meets the standard of C for bicycle LOS. This LOS can be achieved if the
project makes the connection to the Mason Street Trail to the north of the project. This
trail provides access both to the north and to the east of the site.

At one time, there were bike lanes on College Avenue from Harmony Road to Carpenter
Road. When CDOT repaved College Avenue in 2015, the bike lanes were removed
and never replaced. The bike lanes were originally installed as an “experiment” by the
City of Fort Collins under the permission of both CDOT and FHWA. The City was
under the obligation to study the area and write a report on the results of the experiment.
However, it is unknown if that report was ever written or why the bike lanes were
removed. If the bike lanes had remained on College Avenue, then the LOS would be
elevated to a B.
C. Transit Level of Service
The project is located to the south of the normal operations of the Transfort Bus Service.
However, there are bus stops within walking distance to the north and to the south of the
site that will allow people to access the bus system through the Flex routes.
If a connection is made to the Mason Trail, then residents, employees, and customers
will have full access to the site via transit. The City of Fort Collins South Transit is
located north of the site with easy access via the trail.

8.0 Conclusion
This TIS assessed the impacts associated with the Vineyard-Goldelm ODP/PDP
located on the west side of College Avenue in South Fort Collins, CO. The project
proposes to construct 250 apartments, 18 thousand square feet of retail/car sales and
a 42 thousand square foot church. 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. Minor street
left turns at Crestridge and Smokey are problematic in the peak hours.
o Operation at the key intersections will be acceptable under full build-out
of the project.
o The realignment of Crestridge and Smokey should occur with the first
phase of the project when signal warrants are satisfied.
o For the entire project, during the morning peak hour, 294 trip ends can be
expected and 298 trip ends can be expected from the project during the
afternoon peak hours.
o A new traffic signal will be warranted at Crestridge/College and is in
conformance with the Access Control Plan.
o The project will be required to provide auxiliary lanes in conformance
with the State Highway Access Code as discussed in the report.
o Multi-modal level of service can be satisfied for bikes and transit. LOS
for pedestrians cannot be satisfied since there are no sidewalks in the
immediate area. The project will construct the sidewalk system in
conformance with the City Standards.
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.
