1.0 Introduction
This Traffic Impact Study (TIS) is for the proposed Kechter Townhomes project located at the
southwest quadrant of Trilby Road and Ziegler Road in Fort Collins, CO. The purpose of this
TIS is to identify project traffic generation characteristics, to identify potential traffic related
impacts on the adjacent street system, and to develop mitigation measures required for
identified traffic impacts.
Kellar Engineering LLC (KE) has prepared the TIS to document the results of anticipated traffic
conditions in accordance with the Larimer County Urban Area Street Standards (LCUASS) and
to identify any projected impacts to the transportation system. The project is anticipated to
generate approximately 198 daily weekday trips, 13 AM total peak hour trips, and 16 PM total
peak hour trips. See Table 1: Trip Generation.
2.0 Existing Conditions and Roadway Network
The project site is located at the southwest quadrant of the Trilby Road/Ziegler Road
intersection. Trilby Road is classified as a 2-lane Collector adjacent to the project site on the
Fort Collins Master Street Plan. This portion of Trilby Road currently has a thru lane each
direction, bike lanes, detached sidewalks, and a posted speed of 25 mph adjacent to the project
site. Ziegler Road is classified as a 2-lane Collector north of the Trilby Road/Ziegler Road
intersection and unclassified south of the Trilby Road/Ziegler Road intersection on the Fort
Collins Master Street Plan. This portion of Trilby Road currently has a thru lane each direction,
bike lanes, detached sidewalks, and a posted speed of 30 mph adjacent to the project site. See
Figure 1: Vicinity Map.
2.1 Recent Traffic Volumes
Recent peak hour turning movement counts were conducted when school was in session. The
traffic counts were conducted by All Traffic Data Services Inc. on Thursday, February 4, 2021
during the peak hours of adjacent street traffic in 15-minute intervals from 7:00 AM to 9:00 AM,
2:30 PM to 3:30 PM, and 4:00 PM to 6:00 PM. These turning movement counts are shown in
Figure 3 with the count sheets provided in Appendix A.

Figure 2: Site Plan
Kechter Farm Townhomes TIS -Page 6
3.0 Pedestrian Facilities
Detached sidewalks and bike lanes exist adjacent to the project site. These detached
sidewalks and bike lanes provide adequate pedestrian and bicycle facilities.
4.0 Proposed Development
The proposed project consists of 27 townhome dwelling units. Primary access to the
site is proposed from one full-movement access point to Ziegler Road and a right-
in/right-out (RIRO) access point to Trilby Road. See Table 1: Trip Generation and
Figure 2: Site Plan.
4.1 Trip Generation
Site generated traffic estimates are determined through a process known as trip
generation. Rates and equations are applied to the proposed land use to estimate traffic
generated by the development during a specific time interval. The acknowledged source
for trip generation rates is the Trip Generation Report published by the Institute of
Transportation Engineers (ITE). ITE has established trip generation rates in nationwide
studies of similar land uses. For this study, KE used the ITE 10th Edition Trip Generation
Report average trip rates. Since traffic on the adjacent streets and intersections is
highest during the weekday peak hours, this study analyzed the weekday peak hour
traffic. The proposed project is anticipated to generate approximately 198 daily weekday
trips, 13 AM total peak hour trips, and 16 PM total peak hour trips. See Table 1: Trip
Generation.
4.2 Trip Distribution
Distribution of site traffic on the street system was based on the area street system
characteristics, existing traffic patterns and volumes, anticipated surrounding
development areas, and the proposed access system for the project. The directional
distribution of traffic is a means to quantify the percentage of site generated traffic that
approaches the site from a given direction and departs the site back to the original
source. Figure 5 illustrates the trip distribution used for the project’s analysis.
Kechter Farm Townhomes TIS -Page 7
4.3 Traffic Assignment
Traffic assignment was obtained by applying the trip distributions to the estimated trip
generation of the development. Figure 6 shows the site generated peak hour traffic
assignment.
4.4 Short Range Total Peak Hour Traffic
Site generated peak hour traffic volumes were added to the background traffic volumes
to represent the estimated traffic conditions for the short range 2025 horizon. The
background (2025) and short range (2025) total traffic volumes are shown in Figure 4
and Figure 7 respectively. The traffic analysis in this study includes the traffic generated
from the proposed development plus a 2% increase in background traffic per year.
5.0 Traffic Operation Analysis
KE’s analysis of traffic operations in the site vicinity was conducted to determine the
capacity at the identified intersection. The acknowledged source for determining overall
capacity is the Highway Capacity Manual.
5.1 Analysis Methodology
Capacity analysis results are listed in terms of level of service (LOS). LOS is a
qualitative term describing operating conditions a driver will experience while traveling
on a particular street or highway during a specific time interval. LOS ranges from an A
(very little delay) to an F (long delays). A description of the level of service (LOS) for
signalized and unsignalized intersections from the Highway Capacity Manual are
provided in Appendix D.
Kechter Farm Townhomes TIS -Page 8
5.2 Intersection Operational Analysis
Operational analysis was performed for the short range 2025 horizon. The calculations
for this analysis are provided in Appendix F. Using the short range total traffic volumes,
the project is projected to operate acceptably with all studied intersections and access
points meeting LCUASS LOS criteria. See Table 4: 2025 Short Range Total Peak Hour
Operation.
5.3 Access and Intersection Recommendations
The site access locations and proposed turning movements at the study intersections
were reviewed. Due to the existing school’s peak hour traffic, it is recommended that the
proposed site access to Trilby Road (Access #1) be right-in/right-out only. The proposed
site access to Ziegler Road (Access #2) will function safely and appropriately as a full-
movement access. Dedicated right-turn deceleration lanes are not warranted at the site
access points per the LCUASS. Additionally, a northbound left-turn deceleration lane at
the site access to Ziegler Road (Access #2) is not warranted per the LCUASS criteria.
Additionally, the proposed project’s traffic will not trigger the requirement for a
roundabout at the Ziegler Road and Trilby Road/Lady Moon Drive intersection. The
Levels of Service (LOS) of this intersection will meet the City’s LOS requirements with
the development of the project and background traffic in the 2025 Short Range Total
future. The existing intersection controls and geometry at the Ziegler Road and Trilby
Road/Lady Moon Drive intersection are appropriate to meet LCUASS requirements and
accommodate the project’s traffic.

6.0 Findings
Based upon the analysis in this study, the proposed Kechter Townhomes project located at the
southwest quadrant of Trilby Road and Ziegler Road in Fort Collins, CO demonstrates
compliance with the standards in the Larimer County Urban Area Street Standards (LCUASS)
for traffic at the time of development.
The findings of the TIS are summarized below:
• The proposed project is anticipated to generate approximately 198 daily weekday trips,
13 AM total peak hour trips, and 16 PM total peak hour trips.
• The project complies with the Levels of Service (LOS) requirements for traffic, the City of
Fort Collins Transportation Plan, and the Larimer County Urban Area Street Standards
(LCUASS).
• The study intersections will operate acceptably and comply with the intersection levels of
service (LOS) requirements in the LCUASS with the development of the project and
background traffic in the 2025 Short Range Total future.
• The proposed access points will operate safely and demonstrate compliance with the
City’s LOS requirements.
• The proposed project’s traffic will not trigger the requirement for a roundabout at the
Ziegler Road and Trilby Road/Lady Moon Drive intersection. The LOS of this intersection
will meet the City’s LOS requirements with the development of the project and
background traffic in the 2025 Short Range Total future.
• The existing street improvements are sufficient to accommodate the proposed project’s
traffic. See Section 5.2 and Section 5.3.
• Due to the existing school’s peak hour traffic, it is recommended that the proposed site
access to Trilby Road be right-in/right-out (RIRO) only. See Section 5.3.
