I. INTRODUCTION
This intermediate transportation impact study (ITIS) addresses the capacity,
geometric, and control requirements at and near the proposed Harvest Park/Ziegler
Mixed-Use development. The proposed Harvest Park/Ziegler Mixed-Use site is located
west of Ziegler Road and north of Kechter Drive in Fort Collins, Colorado.
During the course of the analysis, numerous contacts were made with the project
architect (Architecture West) 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). A
Base Assumptions Form and related information are 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.

II. EXISTING CONDITIONS
The location of the Harvest Park/Ziegler Mixed-Use 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 immediate area are primarily school or residential. There are
industrial and commercial land uses to the northeast of the Harvest Park/Ziegler Mixed-
Use site (>0.25 miles). Land adjacent to the site is flat (<2% grade) from a traffic
operations perspective. The center of Fort Collins lies to the northwest of the proposed
Harvest Park/Ziegler Mixed-Use site.
Roads
The primary streets near the Harvest Park/Ziegler Mixed-Use site are Ziegler
Road, Rock Creek Drive, and Saber Cat Drive-County Fair Lane (extended).
Ziegler Road is classified as a four-lane arterial street, north of Rock Creek Drive
and a two-lane arterial street, south of Rock Creek Drive on the Fort Collins Master
Street Plan. Currently, Ziegler Road has a four-lane cross section with auxiliary lanes
north of Rock Creek Drive and has a two-lane cross section with auxiliary lanes south of
Rock Creek Drive. At the Ziegler/Rock Creek intersection, Ziegler Road has
northbound and southbound left-turn lanes, one through lane in each direction, and
northbound and southbound right-turn lanes. There are two northbound through lanes
on Ziegler Road, north of the Ziegler/Rock Creek intersection. The Ziegler/Rock Creek
intersection has signal control. At the Ziegler/Saber Cat intersection, Ziegler Road has
a southbound left-turn lane, one southbound through lane, and a combined northbound
through/right-turn lane. The existing speed limit in this area is 40 mph.
Rock Creek Drive is an east-west street designated as a collector street on the
Fort Collins Master Street Plan. Currently, Rock Creek Drive has a two-lane cross
section east of Ziegler Road. At the Ziegler/Rock Creek intersection, Rock Creek Drive
has a westbound left-turn lane, one westbound through-lane, a combined eastbound
left-turn/through lane, and eastbound and westbound right-turn lanes.
Saber Cat Drive and County Fair Lane (extended) are classified as a local
streets. At the Ziegler/Saber Cat intersection, Saber Cat Drive has a westbound left-
turn lane and a westbound right-turn lane. The Ziegler/Saber Cat intersection has stop
sign control on Saber Cat Drive. County Fair Lane is built west of the Harvest
Park/Ziegler Mixed-Use site. The development of the Harvest Park/Ziegler Mixed-Use
site will connect County Fair Lane with Ziegler Road.

Existing Traffic
Recent peak hour traffic counts at the Ziegler/Rock Creek and Ziegler/Saber Cat
intersections are shown in Figure 2. Raw traffic data is provided in Appendix A. The
traffic data at the key intersections was collected in December 2011. The traffic counts
were performed when Fossil Ridge High School was in session.
Existing Operation
The key intersections were evaluated using techniques provided in the 2000
Highway Capacity Manual. Using the recent peak hour traffic shown in Figure 2, the
current peak hour operation is shown in Table 1. Calculation forms are provided in
Appendix B. A description of level of service for signalized and unsignalized
intersections from the 2000 Highway Capacity Manual and a table showing the Fort
Collins Motor Vehicle LOS Standards (Intersections) are provided in Appendix B. The
key intersections operate acceptably during both the morning and afternoon peak hours.
This site is in an area termed “Low Density Mixed-Use Residential.” In “Low Density
Mixed-Use Residential” areas, acceptable operation at unsignalized arterial/collector or
local intersections is level of service F and at collector/local intersections is level of
service C. Acceptable operation at signalized intersections during the peak hours in
“Low Density Mixed-Use Residential” areas is defined as level of service D or better,
overall. Any leg or movement can operate at level of service D.
Pedestrian Facilities
There are pedestrian facilities adjacent to developed properties along Ziegler
Road, Rock Creek Drive, and Saber Cat Drive. There are no sidewalks adjacent to the
Harvest Park/Ziegler Mixed-Use site. As roads are built to arterial/collector standards,
sidewalks will be included in the street cross sections. Sidewalks will be incorporated
within and adjacent to this development.
Bicycle Facilities
Bicycle lanes exist on Ziegler Road and Rock Creek Drive. Bike lanes are not
required on local or connector streets.
Transit Facilities
Currently, Transfort serves this area of Fort Collins with Routes 16 and 17.
Routes 16 and 17 run along Harmony Road, Ziegler Road, and Rock Creek Drive.
Route 16 runs adjacent to the Harvest Park/Ziegler Mixed-Use site.

III. PROPOSED DEVELOPMENT
Harvest Park/Ziegler Mixed-Use is proposed as four townhome buildings with 22
total dwelling units (south portion) and 15,000 square feet of medical/dental office in two
buildings (north portion). Figure 3 shows a site plan of the Harvest Park/Ziegler Mixed-
Use site. The site plan shows an access to/from County Fair Lane. County Fair Lane will
be extended to Ziegler Road with this development. The development will be built in
two phases. The short range analysis (Year 2015) includes development of the south
portion of the Harvest Park/Ziegler Mixed-Use site and the short range analysis (Year
2017) includes full development of the Harvest Park/Ziegler Mixed-Use site.
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 was used to estimate trips that would be
generated by the proposed/expected use at this site. Table 2 shows the expected trip
generation on a daily and peak hour basis.

Trip Distribution
Directional distribution of the generated trips was determined for the Harvest
Park/Ziegler Mixed-Use site. Future year data was obtained from the NFRRTP and other
traffic studies. Figure 4 shows the trip distribution used for the Harvest Park/Ziegler Mixed-
Use site.

Background Traffic Projections
Figures 5 and 6 show the Phase 1 short range (2015) and Full Development
short range (2017) background traffic projections, respectively. Background traffic
projections for the short range future horizons were obtained by reviewing the NFRRTP,
reviewing traffic studies for other developments, and reviewing historic count data for
this area of Fort Collins. Other developments include: various parcels within the
Harmony Tech Park. It is important to note that both the short range (2015) and short
range (2017) background traffic projections assume that County Fair Lane has already
been extended to Ziegler Road.
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. The site generated trip assignment for Phase 1 and Full Development of the
Harvest Park/Ziegler Mixed-Use site is shown in Figures 7 and 8, respectively. The site
generated traffic was combined with the background traffic to determine the total
forecasted traffic at the key intersections. Figures 9 and 10 show the respective Phase
1 short range (2015) and Full Development short range (2017) total traffic at the key
intersections.
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). None of
the stop sign controlled intersections are expected to meet peak hour signal warrants.
Operation Analysis
Operation analyses were performed at the key intersections. The operation
analyses were conducted for the Phase 1 short range analysis, reflecting a year 2015
condition and for the Full Development short range analysis, reflecting a year 2017
condition.
Using the short range (2015) background peak hour traffic volumes, the key
intersections operate as indicated in Table 3. Calculation forms for these analyses are
provided in Appendix C. The key intersections operate acceptably during the peak
hours.
Using the traffic volumes shown in Figure 6, the key intersections operate in the
short range (2017) background condition as indicated in Table 4. Calculation forms for
these analyses are provided in Appendix D. The key intersections operate acceptably
during the peak hours.

Table 5 shows the Phase 1 short range (2015) peak hour operation at the key
intersections with full development of the Harvest Park/Ziegler Mixed-Use site.
Calculation forms for these analyses are provided in Appendix E. The key intersections
operate acceptably during the peak hours.
Table 6 shows the Full Development short range (2017) peak hour operation at
the key intersections with full development of the Harvest Park/Ziegler Mixed-Use site.
Calculation forms for these analyses are provided in Appendix F. The key intersections
operate acceptably during the peak hours.
Geometry
The Phase 1 short range (2015) geometry is shown in Figure 11 and the Full
Development short range (2017) geometry is shown in Figure 12. The geometry at the
Ziegler/Rock Creek intersection is the same as the existing geometry.
Pedestrian Level of Service
Appendix G shows a map of the area that is within 1320 feet and one mile
(school walking area) of the Harvest Park/Ziegler Mixed-Use site. The Harvest
Park/Ziegler Mixed-Use site is located within an area termed as “other,” which sets the
level of service threshold at LOS C for all measured factors. However, since there are
residential land uses within the proposed Harvest Park/Ziegler Mixed-Use site, “School
Walking Area” was used for Fossil Creek High School and Preston Middle/Traut Core
School(s), which sets the level of service threshold at LOS B for all measured factors,
except for “Visual Interest & Amenity,” which is LOS C. Residents of the proposed
Harvest Park/Ziegler Mixed-Use site will go to Bacon Elementary School, which is more
than a mile from the site. There are five destination areas within 1320 feet/one mile of
the proposed Harvest Park/Ziegler Mixed-Use site: 1) Fossil Ridge High School; 2) the
residential neighborhood to the north and northwest of the site; 3) the residential
neighborhood to the south and southwest of the site; 4) the residential neighborhood to
the south of the site; and 5) Preston Middle/Traut Core Knowledge School. In most
cases, sidewalks exist within the pedestrian influence area, except along undeveloped
properties. It is assumed that sidewalks will be completed as properties develop.
Sidewalks will be incorporated within and adjacent to this development. Appendix G
contains a Pedestrian LOS Worksheet. The pedestrian level of service will be
acceptable for all measured categories.
Bicycle Level of Service
Appendix G shows a map of the area that is within 1320 feet of the Harvest
Park/Ziegler Mixed-Use site. Based upon Fort Collins bicycle LOS criteria, 1) Fossil
Ridge High School is the only destination area within 1320 feet of the Harvest
Park/Ziegler Mixed-Use site. The bicycle level of service is acceptable. Appendix G
contains a Bicycle LOS Worksheet.

Transit Level of Service
Currently, Transfort serves this area of Fort Collins with Routes 16 and 17.
Routes 16 and 17 run along Harmony Road, Ziegler Road, and Rock Creek Drive.
Route 16 runs adjacent to the Harvest Park/Ziegler Mixed-Use site. These routes are
considered to be within walking distance of the proposed Harvest Park/Ziegler Mixed-
Use site.
School Traffic
Just prior to the morning peak hour (7:30-8:30am), vehicular traffic at the
Ziegler/Saber Cat intersection was observed. This time period was prior to the
beginning of classes at Fossil Creek High School. Traffic entering Saber Cat Drive,
from both the north and south, was significant. There is a southbound left-turn lane on
Ziegler Road, that removed the left-turns from the through lane. The northbound right-
turns were significant during the observation period (approximately 20 minutes). There
is no northbound right-turn lane. As such, the right-turning traffic caused delays to the
northbound through traffic. The queue extended to/near Sage Creek Road, which is
approximately 600 feet south of Saber Cat Drive. It is recommended that the City of
Fort Collins evaluate this situation and consider installing a northbound right-turn lane
approaching Saber Cat Drive.
Safe Routes To School
With the connection of County Fair Lane to Ziegler Road, it is expected that the
number of pedestrians crossing Ziegler Road at this location will increase. This is
especially true during school times. While the preferred location for pedestrians to
cross Ziegler Road is at the signalized Ziegler/Rock Creek intersection to the north,
there is little doubt that pedestrians will cross Ziegler Road at the Ziegler/Saber Cat-
County Fair intersection. It is recommended that the City of Fort Collins conduct a
“Crosswalk Location and Feasibility Analysis” as described in the Fort Collins
Pedestrian Plan, February 15, 2011. It is recommended that this segment of Ziegler
Road be designated as a reduced speed limit school zone.

IV. CONCLUSIONS/RECOMMENDATIONS
This study assessed the impacts of the proposed Harvest Park/Ziegler Mixed-Use
site development on the short range (2015) street system in the vicinity of the proposed
development. As a result of this analysis, the following is concluded:
• The development of the Harvest Park/Ziegler Mixed-Use site is feasible from a
traffic engineering standpoint. Phase 1 of the Harvest Park/Ziegler Mixed-Use
site will generate approximately 172 daily trip ends, 15 morning peak hour trip
ends, and 17 afternoon peak hour trip ends. At full development, the Harvest
Park/Ziegler Mixed-Use site will generate approximately 570 daily trip ends, 51
morning peak hour trip ends, and 70 afternoon peak hour trip ends.
• Current operation at the key intersections is acceptable.
• In the short range (2015) future, given Phase 1 development of the Harvest
Park/Ziegler Mixed-Use site and an increase in background traffic, the key
intersections operate acceptably during the peak hours, with existing geometry
and intended geometry at the key intersections.
• In the short range (2017) future, given full development of the Harvest
Park/Ziegler Mixed-Use site and an increase in background traffic, the key
intersections operate acceptably during the peak hours, with existing geometry
and intended geometry at the key intersections.
• Acceptable level of service is achieved for pedestrian, bicycle, and transit modes
based upon the measures in the multi-modal transportation guidelines.
• It is recommended that the City of Fort Collins conduct an evaluation of the need for
a northbound right-turn lane on Ziegler Road approaching Saber Cat Drive and the
need for a crosswalk on Ziegler Road with a school zone designation.
