Transportation Memorandum
As noted earlier, Transfort does not serve this area of Fort Collins.
Conclusions and Summary of Findings
This study identified, documented and addressed the transportation impacts of the proposed single family
residential development named Sunrise Ridge in southeast Fort Collins. The following conclusions can
be drawn from the study:
The proposed development is feasible from a traffic engineering standpoint. Once
constructed, the development is estimated to generate only 124 daily trips, including 10 in
the am peak and 13 in the pm peak hour. This does not require a more detailed traffic impact
study.
The addition of the proposed site traffic will have a very minimal (insignificant) impact on
the transportation network. The build -out of the development will complete an important
area connection of Rock Creek Drive to provide connectivity from Ziegler to Strauss Cabin
Road.
Facilities for pedestrians and bicycles exist today to the west of the development. Sunrise
Ridge will provide both pedestrian and bike facilities along their portion of Rock Creek
Drive. Transfort does not provide service to this area.

The overall number of trips is nominal. And because the distribution and assignment of the traffic will
likely be evenly distributed between east and west, the resulting additional peak hour traffic along any
adjacent roadway is less than ten vehicles.

As indicated by the Larimer County Urban Area Street Standards, a transportation memorandum is
appropriate if
• paved pedestrian facilities exist adjacent to the site or the proposed use will not generate any new
pedestrian traffic; and
■ paved bike lanes exist adjacent to the site or the proposed use will not generate any new bicycle
traffic.
The memorandum also needs to discuss the continuity and adequacy of pedestrian and bike facilities
adjacent to the site as well as access to the most direct transit route adjacent to the site.
As noted in the existing conditions, detached paved sidewalks currently exist to the west of the
development along Rock Creek Drive. This would be the most likely path of pedestrians towards
schools. The sidewalks will continue along the new portion of Rock Creek Drive through the
development.
Rock Creek Drive is a City of Fort Collins bikeway (street with bike lane). The completion of Rock
Creek Drive through the proposed development will complete an important east/west link for bike traffic.

Transportation Memorandum
Existing Conditions
The location of the development is 5101 South County Road 7. This is just west of CR 7 (Strauss Cabin
Road) about % of a mile south of Harmony Road. The Observatory Village development is directly to
the west of the proposed Sunrise Ridge, and Rock Creek Drive is stubbed at the western edge of the site
property. The existing land use of the proposed site is rural and primarily vacant save for an existing
single-family dwelling.
The primary streets in the vicinity of the project are CR 7 and Rock Creek Drive. County Road 7 (also
known as Strauss Cabin Road) has a functional classification of a two-lane arterial. The roadway has
two existing travel lanes and the posted speed is 40 mph. There are striped shoulders on either side that
also serve as bike lanes. Rock Creek Drive is a two-lane collector whose typical section varies but
generally includes two travel lanes, bike lanes, occasional parking lanes and detached sidewalks. In
some areas where development has not yet occurred, curb and gutter and/or sidewalks are missing. The
speed limit is 25 mph.
Existing Pedestrian Facilities
Typically, there are existing detached sidewalks on both sides of Rock Creek Drive west of the Sunrise
Ridge development. There are no sidewalks along County Road 7.
Existing Bicycle Facilities
Bicycle lanes are accommodated in the cross section of Rock Creek Drive. The existing shoulders along
County Road 7 can be used as bike facilities.
Existing Transit Facilities
Transfort, the City's transit service does not provide service to this area.
Proposed Development
The Sunrise Ridge Development is a residential development with 13 single family lots total (there is an
existing single family dwelling on one lot). See the enclosed site plan on the next page. The
development access will be to the west and east as Sunrise Ridge will complete the last missing portion
of Rock Creek Drive. This development will complete the connection of the Rock Creek collector
roadway from Ziegler Road to Strauss Cabin Road.
Using the Institute of Transportation Engineers (ITE) Trip Generation Manual, 7m Edition, anticipated
trips for the development are calculated. The land use code is 210 — Single Family Detached Housing,
and details of the anticipated trips are shown below.

This document represents a transportation memorandum per the Larimer County Urban Area Street
Standards associated with the proposed development called Sunrise Ridge in southeast Fort Collins,
Colorado. The purpose of this study is to address the existing and proposed transportation system in the
immediate vicinity of the proposed project and then determine the impact (and mitigation measures if
necessary) of the traffic produced by the proposed development.
