This study assessed the potential impacts of the Campus West
Redevelopment in Fort Collins, Colorado. As a result of the analysis, the
following conclusions were drawn:
The potential impacts of the proposed project were evaluated at
the following intersections: West Elizabeth/City Park and the site access
driveways.
- The traffic impact analyses were performed for existing conditions
and future Years 2000 and 2018. Future background traffic conditions
without the project and the total traffic conditions with completion of the
proposed project, were evaluated.
- Under existing conditions, each of the study intersections is
currently operating at an acceptable level of service.
- For Year 2000 background and total traffic conditions, the.study
intersections are projected to operate at acceptable levels of service.
- For Year 2018 future background and total traffic conditions, the
study intersections are projected to operate at acceptable levels of
service. The required geometry in both the short range future and long
range future is shown in Figure 11. The access driveways to the street
system will be consolidated.
- Pedestrian access to and from the proposed Campus West
Redevelopment is/will be direct and continuous. Pedestrian level of
service will be acceptable for some criteria. Improvements should be made
to the sidewalk system in the area as other properties redevelop or through
a City initiated improvement program. Bicycle level of service will be
acceptable. It is anticipated.that the transit level of service will be
acceptable in the future.

s
done to completely satisfy all of the criteria, although improvements can
be made in ttie area which will make walking a more pleasant experience.
Bicycle Level of Service
This site is directly connected to the on -street bike lanes on West
Elizabeth Street. Therefore, the base connectivity is at level of service
B as shown on Appendix G. Logic would indicate that neither "public school
sites" or recreation sites are priority destinations for the proposed
uses. The site is in an existing commercial area.
Transit Level of Service
'Chere is transit service along West Elizabeth Street and City Park.
The current routes (2, 3, and 11) are within 1320 feet of the site. The
combination of these routes provides good service for this site. Future
transit level of service will be acceptable.

VI. TRAFFIC IMPACT ANALYSIS
The previous two chapters described the development of future traffic
forecasts both with and without the proposed project. Intersection
capacity analyses are conducted in this chapter for both scenarios to
assess the potential impact of the proposed project -generated traffic on
the local street system. Other transportation modes are also addressed in
this chapter.
Traffic Analysis - Year 2000
The peak hour background and total traffic volumes for Year 2000,
illustrated on Figures 7 and 9, respectively, were analyzed to determine
the intersection delay and corresponding level of service. Tables 3 and
4 summarize the results for the respective Year 2000 background and total
traffic conditions. The level of service worksheets for Year 2000
background and total traffic conditions are provided in Appendix C and D,
respectively. As indicated in Tables 3 and 4, the traffic movements at
each of the study intersections are expected to operate at an acceptable
level of service under future traffic conditions for Year 2000. The short
range intersection geometry is depicted on Figure 11. Consolidation of the
multiple driveways is indicated in Figure 11.
Traffic Analysis - Year 2018
The Year 2018 peak hour traffic volumes for background and total
traffic conditions were analyzed to determine the intersection delay and
corresponding level of service. Tables 5. and 6 summarize the results.
Appendix E contains worksheets for Year 2018 background conditions and
Appendix F for Year 2018 total traffic conditions. The level of service
analyses shown, in Tables 5 and 6 indicate that the study intersections will
operate at acceptable levels of service. The long range intersection
geometry is depicted on Figure 11. The geometry will not change between
the short range and long range futures.
Pedestrian Level of Service
The study area for pedestrians is, by definition, destinations which
are within 1320 feet of the site. The potential destinations are shown on
the graphic in Appendix G. The site itself falls into the "Pedestrian
District" category. As mentioned earlier, the site is connected to all of
the potential destinations by existing sidewalks, although some of those
sidewalks do not meet current City Standards. Improvements should be made
to the sidewalk system, especially along West Elizabeth Street. However,
thds redevelopment could not be expected to make. those improvements as a
condition of approval.
The Pedestrian LOS Worksheet is provided in Appendix G. The minimum
levels of service for activity center are A and B for all measured
categories. This level of service will not likely be satisfied for all
categories either currently or in the future. There is little that can be

V. FUTURE TOTAL TRAFFIC PROJECTIONS
The future total traffic projections reflect future traffic
conditions with the traffic from the proposed Campus West Redevelopment
project. The future total traffic projections were developed for Years
2000 and 2018.
Total Traffic Year 2000
The total traffic for Year 2000 was developed by adding traffic from
the proposed project to the background traffic for Year 2000. The
resulting peak hour total traffic projections for Year 2000 are shown on
Figure 9.
Total Traffic Year 2018
The total traffic for Year 2018 was developed by adding traffic from
the proposed project to the background traffic for Year 2018. The
resulting peak hour total traffic projections for Year 2018 are shown on
Figure 10.

The growth reflected in Year 2000 Background Traffic is based on area
wide growth and development. Based upon historical traffic growth and
information from the North Front Range Regional Transportation Plan,
October 1994, the background traffic was determined. The peak hour
background traffic for Year 2000 is depicted on Figure 7.

III. PROPOSED DEVELOPMENT
The project site is proposed to have retail and restaurant uses. The
project site, depicted on Figure 4, is located east of City Park Avenue on
the south side of West Elizabeth Street. The multiple driveways to each
street will be reduced to one to each street.
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, prepared by the Institute of
Transportation Engineers (Trip Generation 6 h Edition
to
estimate trip generation. Table 2 shows the trip generation used
the
proposed project. Land use code 814 (Specialty Retail) and 832 (High
Turnover Restaurant) were used. Peak hour of the generator rates were used
as a conservative analyses procedure. .
Trip Distribution
The directional distribution of the generated trips was determined
for the Campus West Redevelopment. The distribution was determined based
upon a gravity model process, in addition to analysis of the existing
traffic patterns in the area and the type of use proposed at the site. The
trip distribution is provided on Figure 5. It is expected that most
traffic will access the site via the West Elizabeth Street access.
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 6 shows the peak hour
site generated traffic for the proposed project.
Pedestrian Facilities
Currently, there are pedestrian facilities adjacent to the project
site and adjacent to both key streets near the project site. Some of these
sidewalks were built under former City Street Standards and, therefore, do i
not have the parkway between the street and the sidewalk. Some sidewalks
do not meet current or former City Street Standards. These should be
improved when adjacent properties redevelop or the City should make
improvements under an overall improvement program. There are handicap
ramps at 3 of the 4 corners of the West Elizabeth/City Park intersection.
Bicycle Facilities
There are bike lanes striped along West Elizabeth Street.This is
a major bike route for CSU students.
Transit Facilities
Transfort currently serves this area with Routes 2, 3, and 11. There
are transit stops within close proximity of the site.

SITE LOCATION Figure 1
II. EXISTING CONDITIONS
The location of the proposed Campus West Redevelopment is shown on
Figure 1. It is important that a thorough understanding of the existing
conditions be presented.
Land Use
Land uses in the area are commercial and residential. The topography
surrounding the site is essentially flat. The center of Fort Collins is
located east of this site.
Roads
The primary streets, which will serve the proposed project in the
study area, are West Elizabeth Street and City Park Avenue. The
intersection of West Elizabeth/City Park is signal controlled. The site
accesses to West Elizabeth Street and City Park Avenue are stop sign
controlled. There are two driveways to each street.
West Elizabeth Street is an east/west arterial street. Within the
study area, West Elizabeth Street accommodates five travel lanes: two
through lanes in each direction and a center left -turn lane. The left -turn
lane is striped as a two-way continuous left -turn lane adjacent to the
site..
City Park Avenue is a local street that primarily serves the
residential uses north and south of West Elizabeth Street. It has.
exclusive left -turn lanes at the West Elizabeth/City Park intersection.
There is no striping adjacent to the site.
Existing Motor Vehicle Traffic
Peak hour traffic counts at the key intersections are shown on Figure
2. The key intersections included in this study are: West Elizabeth/City
Park and the site accesses. Raw count data is provided in Appendix A.
Since some of these counts were obtained during the summer, they were
adjusted and balanced to reflect a school time condition. The resulting
traffic volumes are shown in Figure 3.
Existing Motor Vehicle Operation
Using the traffic volumes shown in Figure 3 and the existing control,
the key intersections operate as indicated in Table 1. Calculation forms
for these analyses are provided in Appendix B. Appendix B also describes
level of service for unsignalized intersections as provided in the 1994
Highway Capacity Manual. Operation at the key intersections is acceptable.
Acceptable level of service is defined as level of service D or better.

I. INTRODUCTION
This transportation impact study addresses the capacity, geometric,
and control requirements at and near the proposed Campus West
Redevelopment, located south of West Elizabeth Street and east of City Park
Avenue. This transportation analysis addresses potential vehicular impacts
upon the street system, the pedestrian network surrounding the study area,
the bicycle system, and the availability of transit facilities. Traffic
projections will be prepared for future Years 2000 and 2018.
During the course of the analysis, numerous contacts were made with
the project architect/planner (Kenney & Associates), the owner (Rex
Miller), and City staff. This study generally conforms to the format set
forth in the Fort Collins Transportation Impact Study Guidelines. 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 and daily traffic volumes;
- Conduct capacity and operational level of service analyses for all
pertinent modes of transportation.
. This report is prepared for the following purposes:
- Evaluate the existing conditions;
- Estimate the trip generation by the proposed/assumed developments;
- Determine the trip distribution of site generated traffic;
- Evaluate level of service;
- Determine the geometrics at key intersections;
- Determine the impacts of site generated traffic at key intersections;
- Determine pedestrian, bicycle, and transit levels of service.
Information used in this report was obtained from the City of Fort
Collins, the planning and engineering consultants, the developer, research
sources (ITE, TRB, etc.), and field reconnaissance.
