1.0 Introduction
This Traffic Impact Study (TIS) is for the proposed Impala Multi-Family project located at 306
Impala Circle 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 a total of approximately 338 daily weekday trips, 22 AM total peak hour trips, and 28
PM total peak hour trips. See Table 1: Trip Generation.
2.0 Existing Conditions and Roadway Network
The project site is located at 306 Impala Drive, north of the intersection of Mulberry Street and
Impala Drive in Fort Collins, CO. Mulberry Street is an east/west arterial roadway with two thru
lanes, auxiliary turn lanes, bike lanes, sidewalks, and a posted speed of 35 mph. This portion of
Mulberry Street is classified as a 2 Lane Arterial on the City of Fort Collins Master Street Plan.
Impala Drive is a north/south local roadway with one thru lane in each direction, sidewalks, and
a posted speed of 20 mph. Impala Drive is classified as a local street adjacent to the project
site on the Fort Collins Master Street Plan. The intersection of Mulberry Street and Impala Drive
is signalized with a 4-section head phasing the eastbound left-turn lane on Mulberry Street; a 3-
section heading facing the westbound traffic on Mulberry Street; and a 3-section head facing
southbound traffic on Impala Drive.
2.1 Recent Traffic Volumes
Recent peak hour turning movement counts were conducted. The traffic counts were conducted
by All Traffic Data Services Inc. on Wednesday, March 30, 2022 when Poudre High School was
in session during the peak hours of adjacent street traffic in 15-minute intervals from 7:00 AM to
9:00 AM and 3:30 PM to 5:30 PM. The peak hour traffic counts were coordinated to be counted
during the peak start and dismissal times of Poudre High School. These turning movement
counts are shown in Figure 3 with the count sheets provided in Appendix A.

Figure 1: Vicinity Map
Impala Multi-Family TIS -Page 5
Figure 2: Site Plan
Impala Multi-Family TIS -Page 6
3.0 Pedestrian Facilities
Bike lanes, sharrow pavement markings, and sidewalks exist adjacent to the project site.
Additionally, a 2-way buffered bike lane exists along the west side of Impala Drive near
the project site. It is recommended that the project add additional “sharrow” pavement
markings for northbound traffic on Impala Drive north of the intersection of Mulberry
Street and Impala Drive. These sidewalks and bike facilities provide adequate
pedestrian and bicycle facilities.
4.0 Proposed Development
The proposed project consists of a total of 62 multi-family dwelling units. Additionally,
the project proposes to remove a total of 13 existing dwelling units within the project
limits. Therefore, the project adds a net of 49 dwelling units to the existing dwelling
units on the project site. Also, the project is proposing to remove 2 existing dwelling
units and add 6 dwelling units to the portion of the project near the Mulberry Street
access. Therefore, the project is only adding a net of 4 dwelling units to the portion of
the project near Mulberry Street. See Table 1, Table 1b, 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 a total of approximately 338 daily
weekday trips, 22 AM total peak hour trips, and 28 PM total peak hour trips. See Table
1: Trip Generation.
Impala Multi-Family TIS -Page 7
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.
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 per
the North Front Range MPO growth rates.
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.
Impala Multi-Family TIS -Page 8
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 (longer delays). A description of the level of service (LOS) for
signalized and unsignalized intersections from the Highway Capacity Manual are
provided in Appendix D.
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.

6.0 Findings
Based upon the analysis in this study, the proposed Impala Multi-Family project located at 306
Impala Circle 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 a total of approximately 338 daily
weekday trips, 22 AM total peak hour trips, and 28 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 appropriately and demonstrate compliance with
the City’s LOS requirements.
The existing street improvements are sufficient to accommodate the proposed project’s
traffic.
It is recommended that the project add additional “sharrow” pavement markings for
northbound traffic on Impala Drive north of the intersection of Mulberry Street and Impala
Drive.
