westbound approaches, but there is sufficient space for de facto right turn storage. No
improvements are necessary at this intersection/access.
Sight distance evaluations and recommendations
The ground is flat and there are no buildings or landscaping encumbrances to the sight
distance at any of the intersections and access locations. No improvements are necessary
within the area to correct sight distance issues.
Continuity and adequacy of pedestrian and bike facilities
Presently there are bike lanes on the S.E. Frontage Road. They end at the intersection of
SH-14 and to the south on the bend paralleling 1-25. The bike lanes are shown on the Fort
Collins Bike Map without connection to any other bike facilities. Subway will construct a
detached sidewalk adjacent to S.E. Frontage Rd. consistent with other new development
in the area. Currently there is no pedestrian connection to the south and north of the site,
however. Across the street, on the McDonald's side, pedestrians are able to use a
sidewalk up to the SH-14 intersection and cross with a pedestrian signal on a marked
crosswalk. This provides pedestrian access to the residential area north of SH-14. There
are no pedestrian or bike facilities on SH-14.
Appropriateness of the existing roadway signing and striping
The intersections and streets in the area are well striped and signed. No improvements are
necessary to the present signing and striping.
State Highway Access Code
S.E. Frontage Rd. is on the state highway system and thus the State Highway Access
Code regulates access. It is categorized as a Frontage Road. Although there is no direct
access, the Code requires an access permit application due to its proximity and probable
change in use in the current permit. No changes to the current access are foreseen.
Conclusions and Recommendations
This report demonstrates that the proposed Subway will not generate sufficient traffic to
have a meaningful impact or require substantive improvements to the adjacent streets and
intersections. The Subway traffic will function harmoniously with the adjacent land uses
and access locations.

counter. These are shown on the attached Synchro graphics. Presently, the SH-14 and
S.E. Frontage Road intersection operates at LOS C/C in the AM and PM peak hour
respectively. The Denrose Ct. and S.E. Frontage Road intersection operates at LOS B/B.
The Subway restaurant will generate traffic volumes shown in the following chart. The
trip generation is based on customer data and sales provided by the Subway Corporation
for over 1,000 restaurants nationwide. The daily values assume average vehicle
occupancy of 1.5, the same as ITE reports for high -turnover restaurants with seating. To
be conservative the peak- hour trip generation assumes vehicle occupancy of 1.0.

The distribution assumes a 70% west, 25% east, and 5% north split on SH-14. Not much,
if any, will originate from the south. Additional trips (beyond the trip generation values)
were added from the south and east on Denrose Ct. to be conservative. Pass -by trips for
this type of use are around 50%, but for this analysis, the reduction was not taken.
A short-term analysis of operations and impact examined 2013 AM and PM peak hours.
The background traffic increase employed CDOT's 20-year growth factor of 1.31 in this
section of SH-14. The one-year growth rounded up to 1.02. The increase in traffic
occasioned by the new Subway will not have a measurable impact on the intersection and
access operations. The SH-14/S.E. Frontage Rd. intersection will continue to operate at
LOS C/C. The Denrose Ct./S.E. Frontage Rd. intersection will continue to operate at LOS
B/B. The traffic in and out ofthe access on the north side from SH-14 Frontage Rd. is too
small for a realistic evaluation, but it will obviously operate at LOS A/A. For reference,
please see the Synchro graphics and worksheets attached.
Appropriateness of access locations
No direct access to S.E. Frontage Road is proposed. The locations will function
harmoniously with the surrounding land uses, parking lots, and adjacent streets and
intersections.
Location and requirements for turn lanes or accel/decel lanes at the access
Presently on S.E. Frontage Rd. and Denrose Ct. the southbound approach features a right
turn decel lane of approximately 150 ft. and a 100 ft. left turn lane. On the northbound
approach, there is a center turn lane. Shared movements are found on the east and

Technical Report
Traffic Impact Analysis for a New Subway Restaurant
SH-14 (Mulberry) and S.E. Frontage Rd.
Fort Collins, Colorado
Introduction
This technical report analyzes the impact of a new Subway restaurant in accord with the
requirements of Chapter 4 in the Larimer County Urban Area Street Standards. The site
is within the city limits of Fort Collins, thus only certain elements of the standards apply.
The Fort Collins Traffic Engineer approved this level of study on May 15, 2012. The
Base Assumptions are attached for reference. The S.E. Frontage Road is on the state
highway system and access will require a State Highway Access Permit. Note that the
short section of SH-14 Frontage Road on the north side is under CDOT jurisdiction, but
considered as a private drive.
Location and Access
The graphic to the right shows the
location of the project and the adjacent
streets and intersections. The site is
accessed by a driveway to the SH-14
Frontage Rd. on the north side and
through the parking lot of the adjacent
hotel to the intersection of Denrose Ct.
and S.E. Frontage Road. CDOT
indicated that the SH-14 Frontage Rd.
intersection with S.E. Frontage Rd.
functions as a right in/right out only.
Peak hour driveway level of service
Traffic counts at SH-14 and S.E.
Frontage Road and at Denrose Ct. and
