SITE LOCATION Figure 1
that of the Fort Collins Supportive Housing development. The sum of
the peak hour traffic from both parcels was assigned to the site
access. , Short range traffic forecasts were developed for eastbound
Harmony Road from recent peak hour counts and a recent transportation
impact study for the Front Range Baptist Church/School Expansion: The
short range (2010) total peak hour traffic forecast at the site access
is shown in Figure 3. As a right-in/right-out access, the operation
of the right -turn exits from this site will be at level of service C
in the morning and afternoon peak hours. Calculation forms are
provided in Appendix A. This is acceptable Operation. The ,forecasted
right -turning volume at the access to Harmony Road will exceed the
threshold requiring a right -turn auxiliary lane. Harmony Road is
classified as a major arterial street with a design speed of 50 mph
(posted speed is 45 mph). At the design speed, the right -turn lane
should be 435 feet, including a bay taper at 200 feet. Available
design drawings prepared by S.A. Miro, Inc. indicate a right -turn lane
of 420 feet. This is slightly less than the requirement, but in
excess of that needed at the posted speed of 45 mph (375 feet). It is
concluded that the current design will function efficiently and not be
detrimental to the public health, welfare, and safety.
A detached sidewalk will be constructed along the Harmony Road
frontage of this property along with an internal sidewalk system. It
will connect to the existing sidewalk to the east. This will provide
pedestrian access to the Harmony/Hogan-JFK intersection where there
are crosswalks. The primary pedestrian destination will be to the
commercial area to the north (Harmony Centre). Appendix B contains a
Pedestrian LOS Worksheet. The pedestrian level of service will be
acceptable.
There is one bicycle destination within 1320 feet of this site.
It is the Harmony Centre commercial area to the north. The shoulders
on Harmony Road and the bike lanes on JFK Parkway will provide
acceptable bicycle level of service for the Fort Collins Supportive
Housing development.
Transfort Route 1 passes by this site (eastbound) on Harmony
Road. The nearest stop, on JFK Parkway north of Harmony Road, is
within 1320 feet of this site. The transit level of service will be
acceptable.
It is concluded that the Fort Collins Supportive Housing
development will have a minimal traffic impact on the area streets.
The proposed right-in/right-out access will operate acceptably. The
proposed access will also serve the property to the west. Future
development of the property to the west will contribute most of the
vehicular traffic at the proposed access. The pedestrian, bicycle,
and transit level of service will be acceptable.

SUBJECT: Fort Collins Supportive Housing Transportation Impact Study
(File: 06118ME01)
This memorandum constitutes the Transportation Impact Study (TIS)
for the proposed Fort Collins Supportive Housing development. It is
located south of Harmony Road, west of Hogan Drive. The site location
is shown in Figure 1. The scope of this TIS was discussed with Eric
Bracke in late 2006. Due to the low trip generation, a memorandum was
requested that addressed the trip generation, the access to Harmony
Road, and the alternative transportation modes.
A site plan is shown in Figure 2. A right-in/right-out access is
proposed on the south side of Harmony Road approximately 740 feet west
of Hogan Drive. There is a raised median in Harmony Road between
South College Avenue and JFK Parkway. The Fort Collins Supportive
Housing is a building with 23 apartments for physically disabled
people. This type of use is not listed in Trip Generation, 7"'
Edition, ITE, but it would likely have similar trip characteristics as
a senior housing facility. As senior attached housing, 23 units will
generate 80 daily trip ends, 2 morning peak hour trip ends, and 3
afternoon peak hour trip ends. As a conventional apartment, 23 units
will generate 160 daily trip ends, 11 morning peak hour trip ends, and
14 afternoon peak hour trip ends. While the relative difference is
substantial (2-5 times increase), the absolute difference is small,
especially during the peak hours. Therefore, for analysis purposes,
the higher apartment trip generation was used.
The proposed access to this property will also serve the property
to the.west. This area is designated as "Basic Industrial and Non -
retail Employment Activity Center" in the Harmony Corridor Plan.
Using a floor area ratio of 0.30, and a conservative mix of allowed
uses on this parcel (professional office, medical office, and sit-down
restaurant), the trip generation for this adjacent parcel was
estimated at: 1700 daily trip ends, 149 morning peak hour trip ends,
and 170 afternoon peak hour trip ends. Note that the trip generation
of the land uses on the adjacent parcel are significantly higher than
