Figure 3 shows recent peak hour counts at the Ziegler/Rock Creek intersection.
The traffic volumes at the Ziegler/Rock Creek intersection were collected in May 2015.
Raw traffic data is provided in Appendix B. Table 1 shows the current morning and
afternoon peak hour operation of the Ziegler/Rock Creek intersection. The Ziegler/Rock
Creek intersection currently meets the City of Fort Collins Motor Vehicle LOS Standards
during the morning and afternoon peak hours with existing control and geometry.
Calculation forms are provided in Appendix C. A description of level of service for
signalized and unsignalized intersection from the 2010 Highway Capacity Manual is
provided in Appendix C. Table 4-3 (revised per staff comments regarding type of
intersection) showing the Fort Collins Motor Vehicle LOS Standards (Intersections) are
also provided in Appendix C. The Windsong at Rock Creek site is in an area termed
“other.” In areas termed “other,” acceptable overall operation at signalized intersections
during the peak hours is defined as level of service D or better. At signalized
intersections, acceptable operation of any leg and any movement is level of service E.
At unsignalized intersections, acceptable operation is considered to be at level of
service E for any approach leg for an arterial/arterial, arterial/collector and arterial/local
intersections. In such areas, it is expected that there would be substantial delays to the
minor street movements at unsignalized intersections during the peak hours. This is
considered to be normal in urban areas. At unsignalized collector/local intersections,
acceptable operation is considered to be at level of service C for any approach leg.
Figure 4 shows the site plan for the development at Windsong at Rock Creek.
The development at Windsong at Rock Creek is a 64 bed memory care facility.
Currently the site is vacant. Access to the site will be via a right-in/right-out access and
a full movement access to/from Rock Creek Drive. Trip generation is important in
considering the impact of a development such as this upon the existing and proposed
street system. Nursing Home (Code 620) in Trip Generation, 9th Edition, ITE was used to
estimate the trips that would be generated by the proposed/expected uses at a site. This
land use category best fits a memory care facility. A trip is defined as a one-way vehicle
movement from origin to destination. Table 2 shows the expected trip generation on a
daily and peak hour basis. The trip generation of the Windsong at Rock Creek
development resulted in 134 daily trip ends; 11 morning peak hour trip ends; and 14
afternoon peak hour trip ends.
Directional distribution of the generated trips was determined for Windsong at Rock
Creek site and is shown in Figure 5. Figure 6 shows the site generated peak hour traffic
assignment of Windsong at Rock Creek.
Figure 7 shows the short range (2020) background morning and afternoon peak
hour traffic at the Ziegler/Rock Creek intersection. Background traffic volume forecasts
for the short range (2020) future were obtained by reviewing traffic studies for other
developments in this area and reviewing historic counts in the area. Traffic volumes at
the Ziegler/Rock Creek intersection were increased at a rate of 2.0 percent per year.
Table 3 shows the short range (2020) background morning and afternoon peak hour
operation at the Ziegler/Rock Creek intersection. Calculation forms are provided in
Appendix D. The Ziegler/Rock Creek intersection will meet the City of Fort Collins
Motor Vehicle LOS Standards during the morning and afternoon peak hours with the
existing control and geometry in the short range (2020) future.

Figure 8 shows the short range (2020) total morning and afternoon peak hour
traffic at the Ziegler/Rock Creek, Rock Creek/Right-in/Right-out Access, and Rock
Creek/Full Movement Access intersections. Table 4 shows the short range (2020) total
morning and afternoon peak hour operation at the key intersections. Calculation forms
are provided in Appendix E. The Ziegler/Rock Creek, Rock Creek/Right-in/Right-out
Access, and Rock Creek/Full Movement Access intersections will meet the City of Fort
Collins Motor Vehicle LOS Standards during the morning and afternoon peak hours with
the existing control and geometry.
The recommended short range (2020) geometry is shown in Figure 9. The
existing geometry at the Ziegler/Rock Creek intersection is appropriate. The right-
in/right-out access should be designed to discourage other traffic movements. Although
the trip generation/assignment shows little traffic, the City may desire an enhanced
channelization island at this access. Right-turn lanes are not required at the site access
intersections based on Figure 8-4 in LCUASS. According to Figure 8-1 in LCUASS, an
eastbound left-turn lane is not required at Rock Creek/Full Movement Access
intersection. However, with other potential developments using the site access in the
future, Windsong at Rock Creek will restripe this section of Rock Creek Drive to provide
an eastbound left-turn lane.
According to LCUASS, Chapter 7, Table 7-3, on major collector streets, the
distance between high volume driveways and intersections is 200 feet (minimum). The
corner clearance between driveways/alleys (not high volume) and street intersections is
175 feet (minimum). The distance between driveway edges is 75 feet (minimum). The
Right-in/Right-out Access will not be a high volume driveway. The Full Movement
Access will likely have volumes commensurate with that of a high volume driveway in
the future, since it will serve other parcels north of Rock Creek Drive. There are two
driveways that will provide access to the Windsong at Rock Creek site on the north side
of Rock Creek Drive. According to the site plan, the Right-in/Right-out Access is 198
feet east of Ziegler Road (centerline to centerline). Therefore, the Right-in/Right-out
Access meets the corner clearance spacing criterion. The distance between the Right-
in/Right-out Access and the Full Movement Access is 253 feet (centerline to centerline).
Therefore, the spacing between the Right-in/Right-out Access and the Full Movement
Access meets the driveway spacing criterion. The distance between the Full Movement
Access and the driveway to the south (serves Fossil Ridge High School) is 177 feet.
This separation meets the driveway spacing criterion.
The Windsong at Rock Creek site is in an area within which the City requires
pedestrian and bicycle level of service evaluations. Appendix F shows a map of the
area that is within 1320 feet of the Windsong at Rock Creek site. The Windsong at
Rock Creek site is located within an area termed as “transit corridor,” which sets the
pedestrian level of service threshold at LOS C for all measured categories, except for
Directness and Security at LOS B. There are two destination areas within 1320 feet of
the proposed development at Windsong at Rock Creek: 1) the residential area to the
west and 2) Fossil Ridge High School to the southeast. This development will build
sidewalk along the site frontage. Appendix F contains a Pedestrian LOS Worksheet.
The pedestrian level of service will be met.

Based upon Fort Collins Bicycle LOS criteria, there is one destination area within
1320 feet of the Windsong at Rock Creek site: Fossil Ridge High School to the
southeast. Appendix F contains a Bicycle LOS Worksheet. Bicyclists will have access
to Ziegler Road and Rock Creek Drive. The bicycle level of service will be met.
Currently, this area is served by Transfort route 16. The nearest bus stop is at
the Ziegler/Rock Creek intersection.
It is concluded that, with development of the Windsong at Rock Creek, the future
level of service at the key intersections will be acceptable. The Rock Creek/Right-
in/Right-out Access intersection should be designed to discourage left turns. An
eastbound left-turn lane will be restriped at the Rock Creek/Full Movement Access
intersection. The driveway spacing along Rock Creek Drive meets the spacing criteria
in Table 7-3 in LCUASS. The pedestrian and bicycle level of service will be met.
