1.0 Project Description
McDowell Engineering has prepared this Level Two Auxiliary Turn Lane Assessment
for the proposed Pacific Coast Supply warehouse expansion project located in Fort
Collins, CO. The site is already home to a 1,500 square foot(sf) office building, 5,000sf
warehouse and storage yard/garage. The purpose of this transportation impact
analysis is to forecast and analyze the impacts of the additional traffic volumes
associated with the construction of a 20,000sf warehouse building on the site
accesses. Recommendations to mitigate any traffic impacts are also included. The
analysis complies with Colorado Department of Transportation (CDOT) standards.
Refer to the Vicinity Map in Figure 1. A Preliminary Site Plan is shown in Figure 2.

Pacific Coast Supply August 17, 2020 Page 7
2.0 Existing Conditions
2.1 Description of Existing Transportation System
I‐25 Frontage Road: The I‐25 Frontage Road is a local road parallel to Interstate 25.
The I‐25 Frontage Road provides access to local businesses and driveways along the I‐
25 corridor. This local route is classified by the State as Access Category F‐R, Frontage
Road, within the vicinity of the site. The route is generally north‐south through the
region. The posted speed limit is 45mph northbound and 55mph southbound in the
vicinity of the site.
2.2 Site Access Description
The project site currently has two main accesses. The west access, referred to as
access #1, has direct access onto the I‐25 Frontage Road. The south access, access #2,
has access to an unnamed road (referred to as a driveway) with connectivity to the I‐
25 Frontage Road and additional industrial businesses.
2.3 Traffic Data Collection
Morning and evening peak hour turning movement counts were collected at the
intersections of I‐25 Frontage Road and northwest site access, I‐25 Frontage Road and
the shared driveway south of the site, and the shared driveway with the south site
access. Traffic count data was collected on Wednesday, July 1, 2020 on a clear day
during the week. School was not in session and is not expected to impact the traffic
counts at the accesses. The existing office building and warehouse were fully occupied
at the time of data collection. Traffic count data is included in the Appendix of the
report.
Analysis utilized the peak hour of the existing site per the State Highway Access Code
(Access Code). The site’s peak occurred from 8:00 – 9:00am and 4:00 – 5:00pm. All
intersections’ peak hour traffic was calculated based upon the same time periods.
Pacific Coast Supply August 17, 2020 Page 8
3.0 Future Traffic Projections
3.1 Background Infrastructure Assumptions
There are no known proposed development projects that would impact the traffic
projections significantly in the area of the proposed site.
3.2 Background Traffic Growth
CDOT does not have historic traffic volume data for frontage roads. Therefore, the
annual growth rate for the I‐25 Frontage Road was estimated to be a conservative
2.00%. The growth rate has minimal impact on the analysis because the analysis is
generally looking at recommendations for turn lanes at the site accesses onto the I‐
25 Frontage Road. A growth rate was not applied to the shared driveway because the
adjacent parcels have been fully developed.
The I‐25 Frontage Road likely does not have the seasonal peak as I‐25. However, the
CDOT OTIS data was used to determine the corridor’s peak traffic occurs in July.
Therefore, the traffic data was collected during the seasonal peak traffic and no
seasonal adjustment factor is required.
In situations where an access is expected to generate a significant percentage of heavy
vehicles, Section 2.3(4)(e) of the Access Code requires that all large vehicles be
converted to Passenger Car Equivalents (PCEs) prior to the auxiliary turn lane analysis.
Per the Access Code, all vehicles longer than 40 feet shall be considered equivalent to
three passenger cars. Vehicles between 20 and 40 feet in length shall be equivalent
to two passenger cars. Based upon the traffic counts, a 10% heavy vehicle factor was
applied to the I‐25 Frontage Road’s background traffic. A 25% heavy vehicle factor
was applied to the site accesses.
This growth rate was used to project the Year 2020 traffic volumes to Year 2040
volumes. The Year 2020 Existing traffic volumes can be found in Figure 3. The resulting
Year 2020 Background traffic volumes can be found in Figure 4. The resulting Year
2040 Existing Traffic Volumes can be found in Figure 5.

4.0 Project Traffic
4.1 Proposed Land Use
The site is already home to a 1,500 square foot(sf) office building, 5,000sf warehouse
and storage yard/garage. The site has two existing accesses that will be used for the
site.
The proposed new development will include a 20,000sf warehouse addition to the
existing site. This warehouse will allow current materials to be housed inside of a
building. The new warehouse facility is anticipated to cause a minor increase in site
traffic.
4.2 Trip Generation Analysis
The applicant’s anticipated site operations are not consistent with the industrial or
warehousing land uses detailed in the Institute of Transportation Engineers’ (ITE) Trip
Generation Manual1. Therefore, a custom trip generation analysis was prepared
based upon the applicant’s description of the anticipated site operations. The analysis
was based upon the maximum growth and operations that are anticipated for the site.
In situations where an access is expected to generate a significant percentage of heavy
vehicles, Section 2.3(4)(e) of the Access Code2 requires that all large vehicles be
converted to Passenger Car Equivalents (PCEs) prior to the auxiliary turn lane analysis.
Per the Access Code, all vehicles longer than 40 feet shall be considered equivalent to
three passenger cars. Vehicles between 20 and 40 feet in length shall be equivalent
to two passenger cars. The custom trip generation analysis included PCE factors based
upon the type of vehicles. All figures include the volumes in PCEs.
4.3 Site‐Generated Traffic
The total site traffic anticipated with the current buildings and 20,000sf warehouse
expansion is expected to be 88 external vehicle trips over the course of an average
weekday, including 19 trips during the morning peak hour and 12 trips during the
evening peak hour.
Refer to Table 1 for trip generation calculations and further breakdown of these trips.

4.4 Directional Distribution
The distribution of project‐generated traffic on the surrounding roadway network is
influenced by several factors including the following:
The location of the site relative to other facilities and the roadway network
The configuration of the existing and proposed adjacent roadway network
Relative location of neighboring population centers
Based upon existing traffic counts and the location of the project in relation to nearby
businesses and I‐25 access, the following project‐generated directional distribution is
as follows:
Sixty percent (60%) of site‐generated traffic will originate to/from the north
on the I‐25 Frontage Road.
Forty percent (40%) of site‐generated traffic will originate to/from the south
on the I‐25 Frontage Road.
The anticipated directional distribution of project‐generated traffic is depicted in
Figure 6.
4.5 Traffic Assignment and Total Traffic
When the trip generation expected for this site is applied to the estimated trip
distribution, the result is the anticipated assignment of trips on the roadway system.
Figure 7 depicts the total vehicle trips that are anticipated from the site. This is
inclusive of the existing traffic and additional traffic from the expansion. All volumes
are depicted in PCEs.
The short‐term forecasted Year 2020 traffic is depicted in Figure 8. The long‐term Year
2040 traffic is shown in Figure 9.

5.0 Transportation Impact Analysis
5.1 State Highway Access Permits
The site traffic at the northwest access to the I‐25 Frontage Road is anticipated to
increase from 4vph to 18vph (in PCEs) in the morning peak hour and remain the same
in the evening peak hour.
Section 2.6(3) of the State Highway Access Code4 (Access Code) requires a new access
permit when there is a land use change and/or the driveway volume is anticipated to
increase by more than twenty percent. The proposed project is anticipated to add
more than 20% traffic growth to the site access. Therefore, a new State Highway
Access Permit will be required for the proposed site access.
5.2 State Highway Turn Lane Analysis
The State Highway Access Code establishes the need for auxiliary turn lanes. Several
criteria apply when determining the traffic volume thresholds.
I‐25 Frontage Road classification = F‐R
I‐25 Frontage Road Speed Limit = 45mph northbound and 55mph southbound
Turning Movement Volumes as shown in Table 2
Table 2: Auxiliary Turn Lane Requirements
Southbound Left Turn Deceleration Lane: Section 3.8(5) of the State Highway Access
Code, details the volume requirements for necessitating the construction of auxiliary
turn lanes at an access to the State highway system. The traffic volumes generated
by the proposed land use do not warrant the need for any additional auxiliary turn
lanes at the I‐25 Frontage Road accesses.

5.3 Sight Distance
The posted speed limit on the I‐25 Frontage Road is 45mph northbound and 55mph
southbound. The sight distance was analyzed conservatively for the higher 55mph
speed.
Sight Distance Along Highway: Table 4‐1 of the State Highway Access Code states that
the design sight distance along the highway shall be 550’ for a 55mph posted speed.
No grade adjustment is required for the southbound or northbound approach. Sight
distance is more than 550’ in both the northbound and southbound directions.
Entering Sight Distance: Table 4‐2 of the State Highway Access Code states that 935’
of entering sight distance is required for a two‐lane roadway with a posted speed of
55mph to accommodate multi‐unit trucks. No grade adjustment is required. Sight
distance is greater than 935’ for both approaches.
5.4 Access Design Criteria
The proposed access shall be constructed per Section 4 of the Access Code. The City
of Fort Collins’ regulations will also apply.
Pacific Coast Supply August 17, 2020 Page 21
6.0 Recommendations and Conclusions
The purpose of this transportation impact study is to forecast and analyze the impacts
of the site’s additional traffic volumes on the site access.
The site is already home to a 1,500 square foot(sf) office building, 5,000sf warehouse
and storage yard/garage. The site has two existing accesses that will be used for the
site.
The proposed new development will include a 20,000sf warehouse addition to the
existing site. This warehouse will allow current materials to be housed inside of a
building. The new warehouse facility is anticipated to cause a minor increase in site
traffic. The existing accesses will provide access to the new warehouse.
Trip Generation: The total site traffic anticipated with the current buildings and
20,000sf warehouse expansion is expected to be 88 external vehicle trips over the
course of an average weekday, including 19 trips during the morning peak hour and
12 trips during the evening peak hour.
State Highway Access Permits: A new State Highway Access Permit will be required
for the proposed site use.
Auxiliary Turn Lanes: The traffic volumes generated by the proposed land use do not
warrant the need for any additional auxiliary turn lanes at the I‐25 Frontage Road
accesses.
Access design must conform to the State Highway Access Code’s criteria in Section 4.
The City of Fort Collins’ regulations will also apply.
Sight Distance: Sight distance exceeds the requirements of 550’ and 935’ for sight
distance along the highway and entering sight distance, respectively.
Summary: The proposed Pacific Coast Supply expansion project is anticipated to be
successfully accommodated by the I‐25 Frontage Road.
