This intermediate transportation impact study assessed the impacts
of Columbine South Development on the short range (2006) street system
in the vicinity of the proposed development. As a result of this
analysis, the following is concluded:
The development of Columbine South Development is feasible from a
traffic engineering standpoint. A nursing home with 131 beds,
Columbine South Development will generate approximately 310 daily
trip ends, 23 morning peak hour trip ends, and 29 afternoon peak
hour trip ends.
Currently, the key intersections operate acceptably with current
control and geometry.
- In the short range (2006) future, signals will not likely be
warranted at the Lemay/Rule intersection. Signals are warranted
and will be installed at the Lemay/Oakridge intersection.
In the short range (2006) background traffic future, the key
intersections will operate acceptably.
- In the short range (2006) future, given full development of
Columbine South Development and an increase in background traffic,
the key intersections will operate acceptably. The recommended
short range (2006) geometry is shown in Figure 9.
- Acceptable level of service for pedestrian and bicycle modes will
be achieved for all factors. The transit level of service will be
acceptable in the future.

reflects the existing geometry at the key existing intersections.
Pedestrian Level of Service
Appendix G shows a map of the area that is within 1320 feet of the
Columbine South Development. The Columbine South Development is located
within an area termed as "transit corridor," which sets the level of
service threshold at LOS B for all measured categories, except visual
interest and amenities, which is C. There are four destination areas
within 1320 feet of the proposed Columbine South Development: 1) the
commercial areas to the north, 2) the residential/commercial areas to
the east, 3) the residential areas to the south, and 4) the
residential/commercial areas to the west. In most cases, sidewalks
are completed within the pedestrian influence area. It is assumed
that sidewalks will be completed as properties develop. Appendix G
contains a Pedestrian LOS Worksheet.
Bicycle Level of Service
Appendix G shows a map of the area that is within 1320 feet of
Columbine South Development. The bicycle priority destinations are the
commercial centers to the north and northwest. Based upon Fort
Collins bicycle LOS criteria, the minimum level of service threshold
for bicycles is LOS C. There are bicycle facilities along Wheaton
Drive and Lemay Avenue. The Columbine South Development is directly
connected to the bike lanes on Lemay Avenue. This achieves level of
service B connectivity.
Transit Level of Service
This area is not currently served by Transfort. Since this is an
intermediate transportation impact study the long range transit system
and long range transit level of service is not relevant. However, the
Columbine South Development is located within 1320 feet of a future
"enhanced travel corridor" along Harmony Road. In the future, transit
service will be improved as depicted on the Fort Collins Transit
System Plan. The future level of service will be in the B category.

Trip Assignment
Trip assignment is how the generated and distributed trips are
expected to be loaded on the street system. The assigned trips are the
resultant, of the trip distribution process. Figure 7 shows the site
generated peak hour traffic assignment. Figure 8 shows the total (site
plus background) short range (2006) peak hour traffic at the key
intersections.
Signal Warrants
As a matter of policy, traffic signals are not installed at any
location unless warrants ,are met according to the Manual on Uniform
Traffic Control Devices (MUTCD). There are eight signal warrants in the
MUTCD. The peak hour warrant is the one that is the easiest to predict
in a transportation impact study, since these are analysis periods that
are typically included in a transportation impact study. While a peak
hour signal warrant would not be used to warrant a signal at this
location, it would give a reasonable indication whether other signal
warrants would be met. The peak hour warrant sheets are provided in
Appendix D for the Lemay/Rule and Lemay/Oakridge intersections. The
minor streets (Rule Drive and Oakridge Drive) were evaluated with two
approach lanes on both the eastbound and westbound legs. During all of
the analysis times (recent and future), the peak hour warrant is/will
not be met at the Lemay/Rule intersection. At the Lemay/Oakridge
intersection, the peak hour warrant is met in the short range afternoon
peak hour with the background and total traffic. In addition to this,
the City of Fort Collins conducted a signal warrant in July 2004. The
Lemay/Oakridge intersection met Warrant 1. This was discussed in the
scoping meeting. This intersection will be analyzed with signal
control.
Operation Analysis and Geometry
Capacity analyses were performed at the Lemay/Rule,
Lemay/Oakridge, Wheaton/Rule, Lemay/Site Access, and Rule/Site Access
intersections. The operations analyses were conducted for the short
range analysis future, reflecting a year 2006 condition.
Using the traffic volumes shown in Figure 6 and the existing
geometrics, the key intersections operate in the short range (2006)
background traffic future as indicated in Table 3. Calculation forms
for these analyses are provided in Appendix E. The key intersections
will operate acceptably.
Using the traffic volumes shown in Figure 8 and the existing
geometrics, the key intersections operate in the short range (2006)
total traffic future as indicated in Table 4. Calculation forms for
these analyses are provided in Appendix F. The key intersections will
operate acceptably.

III. PROPOSED DEVELOPMENT
The Columbine South Development is a proposed nursing home
development, located at the northeast quadrant of the Lemay/Rule
intersection in Fort Collins. Figure 4 shows a site plan of the
Columbine South Development. The short range analysis (year 2006)
includes development of the Columbine South Development and an
appropriate increase in background traffic. Since this is an
intermediate level transportation impact study, a long range analysis
is not required. The site plan shows two accesses to the Columbine
South Development via full -movement accesses to Lemay Avenue and to
Rule Drive.
Trip Generation
Trip generation is important in considering the impact of a
development such as this upon the existing and proposed street system.
Trip generation information contained in Trip Generation, 7`h Edition,
ITE was used to estimate trips that would be generated by the
proposed/expected uses at this site. Table 2 shows the expected trip
generation on a daily and morning/afternoon peak hour basis.

* Directional distribution based on hospital land use
Trip Distribution
Directional distribution of the generated trips was determined for
Columbine South Development based upon a gravity model analysis and
engineering judgment. Figure 5 shows the trip distribution used for the
short range (2006) analysis future. The trip distribution calculations
are provided in Appendix A. The trip distribution was discussed in the
scoping meeting.
Background Traffic Projections
Figure 6 shows the short range (2006) background traffic
projections. Background traffic projections for the short range future
horizon were obtained by reviewing the NFRRTP, reviewing traffic studies
for other developments, and reviewing historic count data for this area
of Fort Collins. The 2004 traffic counts were increased at the rate of
2.25 percent per year to the year 2006.

RECENT PEAK HOUR TRAFFIC
Figure 2
5
Existing Traffic
Recent peak hour traffic volumes at the key intersections are
shown in Figure 2. The traffic counts at the key intersections were
obtained in October 2004, except for the Lemay/Oakridge intersection
which was obtained in August 2004. The Lemay/Oakridge intersection was
adjusted to reflect school traffic since the count was obtained in the
summer. The adjusted recent traffic is shown in Figure 3. Raw count
data is provided in Appendix B. ,
Existing Operation
The key intersections were evaluated using techniques provided in
the 2000 Highway Capacity Manual. Using the peak hour traffic shown in
Figure 2, the peak hour operation is shown in Table 1. Calculation
forms are provided in Appendix C. A description of level of service for
signalized and unsignalized intersections from the 2000 Highway Capacity
Manual -and a table showing the Fort Collins Motor Vehicle LOS Standards
(Intersections) are also provided in Appendix C. The key intersections
operate acceptably during both the morning and afternoon peak hours.
The Columbine South Development site is in an area termed "low -density
mixed -use residential." In low -density mixed -use residential areas,
acceptable operation at unsignalized intersections during the peak
hours is defined as level of service F for any approach leg for an
arterial/local intersection and level of service C for any approach leg
for a collector/local intersection.
Pedestrian Facilities
Sidewalks exist adjacent to existing developments on all area
streets. This site is within 1320 feet of: existing retail uses,
commercial/office uses, light industrial uses, and other residential
uses.
Bicycle Facilities
There are bicycle facilities along Lemay Avenue and Wheaton
Drive.
Transit Facilities
This area is not currently served by Transfort.

I. INTRODUCTION
This intermediate transportation impact study addresses the
capacity, geometric, and control requirements at and near the proposed
location of the Columbine South Development. The Columbine South
Development is located on the northwest corner of the Lemay Avenue/Rule
Drive intersection in Fort Collins, Colorado.
During the course of the analysis, numerous contacts were made
with the project developer (Columbine Health Systems), the project
planner (VF Ripley), the Fort Collins Transportation Planning Staff, and
the Fort Collins Traffic Engineering Staff. The Transportation Impact
Study Base Assumptions form is provided in Appendix A. This
intermediate transportation impact study generally conforms to the
format set forth in the Fort Collins transportation impact study
guidelines as contained in the "Larimer County Urban Area Street
Standards" (LCUASS). The study involved the following steps:
- Collect physical, traffic, and development
- Perform trip generation, trip distribution,
- Determine peak hour traffic volumes;
- Conduct capacity and operational level of
intersections;
- Analyze signal warrants;
data;
and trip assignment;
service analyses on key
- Conduct level of service evaluation of pedestrian, bicycle, and
transit modes of transportation.
