Re: Trip Generation Letter
The Hub Town Homes
West Side of College Avenue (US-287), Between Parker Street and Stuart Street
1751 South College Avenue
Fort Collins, Colorado
Dear Mr. Matesi,
The purpose of this letter is to provide trip generation for the proposed Hub Town Homes to be
located along the west side of College Avenue (US-287), between Parker Street and Stuart Street, in
Fort Collins, Colorado. Specifically, the project is to be located at 1751 South College Avenue. A
vicinity map of the project area is illustrated in Figure 1 attached. The new Hub Town Homes project
is proposed to include 10 town home units in two buildings with 29 beds. Site plans are attached with
this letter.
The Hub Town Homes are located at 1751 South College Avenue, next to the Summit student
housing development. The site is developing with 10 two-story town homes. Nine of the units will
include three bedrooms, while one of the units will include two bedrooms, for a total of 29 beds. Each
unit has an attached two car garage, except for the two-bedroom unit which has an attached one car
garage. Circulation through the site will be provided by a north-south access roadway in between the
two buildings, with five (5) town homes located on each side with garage door access fronting the
interior roadway. Of relevance, this proposed development is near the Mason Corridor Transitway to
the west of the site. This project is also located within the City of Fort Collins identified Transit
Oriented Development (TOD) zone. Based on this, it is believed that alternate modes of travel will be
used by the residents of these town homes.
Primary access to the site will be provided by Prospect Road and College Avenue (US-287). Direct
access to the project is proposed form the existing right-in/right-out access along College Avenue
(US-287) along the south side of the site, which is located approximately 180 feet (measured edge to
edge) north of Stuart Street. The existing northern right-in/right-out access, located approximately
300 feet (again measured edge to edge) north of Stuart Street will be removed with development of
the project. The removal of this access will likely require a Colorado Department of Transportation
(CDOT) access permit. Shared cross access will be available through this project site and is
available through the existing adjacent properties as well. Due to this, it is believed that project traffic
will use the existing three-quarter movement intersection along College Avenue located
approximately 350 feet (edge to edge) north of the existing southern project access. Project traffic
may also use the existing internal drive aisles through the shopping center to the north to access
Prospect Road.
College Avenue (US-287) is owned and maintained by CDOT. The State Highway Access Category
Schedule categorizes the segment of College Avenue (US-287) through the study area as NR-B: Non
Rural Arterial. College Avenue provides three lanes of travel each direction, northbound and
southbound, and has a posted speed limit of 40 miles per hour. College Avenue has a raised median
through the project study area. The existing intersections of College Avenue (US-287) with Prospect
Road and Stuart Street are signalized.

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. Based on the unique nature of this use with close proximity to the
Colorado State University campus and being within the TOD zone, it was determined through
discussions with City staff that the City of Fort Collins developed Student Housing trip generation
rates were a more accurate representation of expected site generated trips for this project. These
rates are 2.65 trips per bed per day, with a morning peak hour trip rate of 0.19 trips per bed and the
afternoon peak hour rate being 0.42 trips per bed. Parking counts at the District as identified within
“The Hub Parking Generation Letter”, completed by Kimley-Horn and Associates, Inc in October 2016
were used in determining the proportion of entering and exiting traffic during the peak hours. Based
on this, the Hub Town Homes are expected to generate approximately 77 daily weekday trips. Of
these, six (6) trips are expected to occur during the morning peak hour, while 12 trips are expected
during the afternoon peak hour.
To provide comparative trip generation calculation, Kimley-Horn used the ITE Trip Generation, 9th
Edition (current), average rate equations that apply to Apartment (ITE Code 220). The acknowledged
source for trip generation rates is the Trip Generation Report1 published by the Institute of
Transportation Engineers (ITE). ITE has established trip rates in nationwide studies of similar land
uses. Based on this, 10 units of the Hub Town Homes if anticipated to be apartments would be
expected to generate approximately 66 daily weekday trips. Of these, five (5) trips would be expected
to occur during the morning peak hour, while six (6) driveway trips are expected during the afternoon
peak hour. Therefore, the equations for the student housing provide a more conservative analysis
than the average rates for the ITE Apartment land use code. Again, this is provided for informational
purposes only.

As summarized in the table, The Hub Town Homes are anticipated to generate 77 daily weekday
trips. Of these, six (6) trips are expected to occur during the weekday morning peak hour while 12
trips are expected to occur during the afternoon peak hour.
Distribution of site traffic on the street system was based on the area street system characteristics,
existing traffic patterns, existing and anticipated surrounding development areas and type, expected
roadway improvements, 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. Traffic assignment was obtained by
applying the distribution to the estimated traffic generation of the project shown in the above Table.
The attached Figure 2 illustrates the expected project trip distribution and traffic assignment. As

shown in the Figure, the resultant traffic assignment is very small at all anticipated points of access to
the adjacent public street network.
Based on these results, development of The Hub Town Homes, proposed to include 10 town home
units with 29 beds at 1751 South College Avenue is not anticipated to cause a significant impact to
the surrounding street network due to the low trip generation. The Hub Town Homes are anticipated
to generate 77 daily weekday trips. Of these, six (6) trips are expected to occur during the morning
peak hour while 12 trips are expected to occur during the afternoon peak hour. Therefore, based on
conversations with City staff, it is believed that additional traffic analysis will not be needed for this
project. If you have any questions or require anything further, please feel free to call me at (303) 228-
2304.
