HomeMy WebLinkAboutTIMBERLINE VILLAGE - HARMONY SCHOOL SHOPS, 4TH FILING - PDP - 10-03 - REPORTS - TRAFFIC STUDY (3)IV. CONCLUSIONS
This study assessed the impacts of the Timberline Village
development on the short range and long range street system in the
vicinity of the proposed development. As a result of this analysis, the
following is concluded:
The development of the Timberline Village is feasible from a
traffic engineering standpoint. At full development, the
Timberline Village will generate approximately 7857 external daily
trip ends, 397 external morning .peak hour trip ends, and _777
external afternoon peak hour trip ends.
Current operation at the key intersections is acceptable.
while the Timberline/Milestone intersection will meet peak hour
signal warrants, this intersection will not be signalized
according to Fort Collins Traffic Operations: The Harmony/MHP
Access/Snow intersection may be signalized at some future date.
In the short range (2006) future, given development of the
Timberline Village and an increase in background traffic, the key
intersections will operate acceptably, overall.
- In the long range (2022) future, given development of the
Timberline Village, the key intersections will operate acceptably,
overall.
- A channelized T-intersection will operate acceptably at the
Timberline/Milestone intersection. If this is selected, the
existing median area will require reconstruction.
Acceptable level of service is achieved for pedestrian, bicycle,
and transit modes based upon the measures in the multi -modal
transportation guidelines, except for the connectivity standard to
the Mobile Home Park and the homes on the west side of Timberline
Road.

LONG RANGE (2022) GEOMETRY
25
Figure 13
The long range (2022) geometry is shown in Figure 13. The only
difference between the short range and long range geometry are the
additional through lanes on Harmony Road. In the long .range future, the
geometry is that which is practical at the Harmony/Timberline
intersection. If the City widens Timberline Road to a six -lane cross
section or builds turn lanes where they do not currently exist, then the
level of service shown in Table 6 will be improved.
Pedestrian Level of Service
Appendix H contains a map of the pedestrian influence area that
is within 1320 feet of the Timberline Village site. There will be
five pedestrian destinations within 1320 feet of the Timberline
Village. These are: 1) the residential area northeast of the site,
2) the Poudre Valley Hospital South Campus, 3) the Harmony Crossing
commercial area, 4) the Mobile Home Park, and 5) the few homes west of
Timberline Road. This site is in an area type termed "transit
corridor." There are some sidewalks adjacent to the Timberline
Village site. With this development, it is assumed that gaps in the
sidewalk system will be completed. The pedestrian level of service
(LOS) for this area type is B for all factors, except visual interest
and amenities, which is LOS C. The Pedestrian LOS Worksheet is
provided in Appendix H. With the assumed future pedestrian facilities
adjacent to the site, the pedestrian level of service will be
acceptable for those destinations within 1320 feet of the Timberline
Village, except for the continuity factor. There will be a gap in the
sidewalk adjacent to the Mobile Home Park and on the west side of
Timberline Road.
Bicycle Level of Service
Appendix H contains a map of the bicycle influence area that is
within 1320 feet of the Timberline Village site. . .Based upon Fort
Collins bicycle LOS criteria, there are two destination areas within
1320 feet of the Timberline Village site. These are the 1) Poudre
Valley Hospital South Campus and 2) the Harmony Crossing commercial
area. A bicycle LOS worksheet is provided in Appendix H. The bicycle
level of service is acceptable.
Transit Level of Service
Currently, this area has no transit service. The Fort Collins
Transit System Map shows that Timberline Road will have high frequency
(20 minute) transit service and that Harmony Road will be an enhanced
travel corridor (10 minute service) in the future. A future transit
level of service worksheet is 'provided in Appendix H. Transit level
of service will be acceptable.

acceptably. The Timberline/Milestone intersection was analyzed with
the current geometric configuration and as a channelized T-
intersection. With the current geometry, the delays to the minor
street leg. (Milestone) will be unacceptable. While the level of
service is shown to be F, the delays to each approach vehicle are not
reasonable. The channelized T-intersection reduces the delays to the
minor street leg, significantly.
Using the traffic volumes shown in Figure 11, the key
intersections operate in the long range total condition as indicated
in Table 6. Calculation forms for these analyses are provided in
Appendix F. The key intersections will operate acceptably, overall.
As with the long range background traffic, some movements and one leg
are expected to operate at level of service F at the Harmony/Timberline
intersection. It is expected that motorists .will seek alternative
routes if delays become excessive. At the Timberline/Milestone
intersection, the channelized T-intersection reduces the delays to the
minor street leg, significantly.
Since acceptable operation was achieved at the Timberline/
Milestone intersection with a channelized T-intersection, the connection
from the Timberline Village site to the MHP Access was not analyzed. If
the City decided that westbound minor street left turns should be
eliminated at the Timberline/Milestone intersection, then the southbound
left turns at the Harmony/Timberline intersection (Figures 8 and 9)
would move to the MEP Access. Also, the southbound through vehicles at
the Harmony/Timberline intersection (Figures 8 and 9) would move to the
Harmony/RT-in/RT-out/LT-in intersection and westbound left turns at the
Harmony/Timberline intersection. These changes would not cause a
significant change in operation of the key intersections. However,
elimination of the westbound minor . street left turns at the
Timberline/Milestone intersection would cause the existing traffic to
find another route. That route may be through the parking lot of the
Timberline Village development. The City should consider this
possibility before taking the action of restricting movements at the
Timberline/Milestone intersection.
Geometry
The short. range (2006) geometry is shown in Figure 12. The short
range geometry is the same as the current geometry at the Harmony/
Timberline intersection. The Timberline/Milestone intersection was
analyzed as a channelized T-intersection, as shown in Tables 5 and 6. A
schematic diagram of a channelized T-intersection is provided in
Appendix G. A channelized T-intersection allows the minor street left
turns to be made in two steps. In the first step, the minor street left
turn crosses the northbound lanes and enters a protected median area.
In this maneuver, the major street traffic consists of the northbound
traffic and the southbound major street left turns. The second step is
a merging maneuver into the southbound through traffic lanes on
Timberline Road. A channelized T-intersection requires a raised median.
The existing median on Timberline Road will require reconstruction in
order to accomplish this.

resultant of the trip distribution process. Figure 8 shows the short
range (2006) site generated peak hour traffic assignment for the
Timberline Village. Figure 9 shows the long range (2022) site
generated peak hour traffic assignment for the Timberline Village. In
the initial traffic assignment, no traffic ,was assigned to the
Harmony/MHP Access intersection. Initial site plans indicate no
connection from the Timberline Village to the MHP Access. It is
expected that this connection would not be made unless it was the only
route for Timberline Village exits to the east. It is also the
function of the ability to secure easement to the MHP Access. Figure
10 shows the short range (2006) total morning and afternoon peak hour
traffic at the key intersections. Figure 11 shows the long range
(2022) total 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. While the Timberline/Milestone intersection
will meet peak hour signal warrants, this intersection will not be
signalized according to Fort Collins- Traffic Operations. The
Harmony/MHP Access/Snow intersection may be signalized at some future
date. Traffic on the future south leg (Snow Drive) will likely cause
the peak hour signal warrant to be met.
Operation Analysis
Capacity analyses were performed at the key intersections. The
operations analyses were conducted for the short range analysis,
reflecting a year 2006 condition. The long range analysis reflects a
year 2022 condition.
Using the traffic volumes shown in Figure 6, the key intersections
operate in the short range background condition as indicated in Table 3.
Calculation forms for these analyses are provided in Appendix C. The
key intersections will operate acceptably during the peak hours.
Using the traffic volumes shown in Figure 7, the key intersections
operate in the long range background condition as indicated in Table 4.
Calculation forms. for these analyses are provided in Appendix D. The
key intersections will operate acceptably, overall. However, in the
afternoon peak hour, some movements are expected to operate at level of
service F at the Harmony/Timberline intersection. The geometry at this
intersection is the most that could reasonably be expected. If delays
become excessive, motorists will seek alternative routes.
Using the traffic volumes shown in Figure 10, the key
intersections operate in the short range total condition as indicated
in Table 5. Calculation forms for these analyses are provided in
Appendix E. The key intersections, with improvements, will operate

SITE PLAN Figure 4
III. PROPOSED DEVELOPMENT
Timberline Village is a commercial development consisting of a
grocery store, 3 sit-down restaurants, a drive-in bank, and 34,750
square feet of retail. Timberline Village is located in the northeast
quadrant of the Harmony/Timberline intersection in Fort Collins. Figure
4 shows a site plan of the Timberline Village. The short range analysis
(Year 2006) includes development of the Timberline Village and an
appropriate increase in background traffic, due to normal growth and
other potential developments in the area. The long range analysis year
is considered to be 2022.
The site plan shows three accesses to.the Timberline Village site.
One access is a full -movement access to Milestone Drive. Milestone
Drive intersects with Timberline Road at a full movement, stop sign
controlled intersection. The second access, to Timberline Road, is a
right-in/right-out only access. The third access, to Harmony Road, is
a right-in/right-out/left-in access.
Trip Generation
Trip generation is important in considering the impact of a
development such as this upon the existing and proposed street system. A
compilation of trip generation information contained in Trip Generation,
6t° 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 peak hour basis.
Trip Distribution
Directional distribution of the generated trips was determined for
the Timberline Village. Future year data was obtained from the NFRRTP
and other traffic studies. Figure 5 shows the short range (2006) and
long range (2022) trip distribution used for the Timberline Village.
Background Traffic Projections
Figures 6 and 7 show the respective short range (2006) and long
range (2022) background traffic projections. Background traffic
projections for the short range and long range future horizons were
obtained by reviewing the NFRRTP, reviewing traffic studies for other
developments, and reviewing historic count data for this area of Fort
Collins. The long range background traffic assumes that all vacant
parcels in the area of the Timberline Village are developed.
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

RECENT PEAK HOUR TRAFFIC

Figure 2
Existing Traffic
Recent peak hour traffic counts at the key intersections are shown
in Figure 2. Raw traffic data is provided in Appendix A. The traffic
data for the Harmony/Timberline intersection was collected in January
2002, and the traffic data for the Timberline/Milestone and
Timberline/Timberline Lane/RT Access intersections was collected in
August 2002. Traffic data at the Harmony/MHP Access intersection was
obtained in October 2002. Since, the traffic counts were performed on
different days and at different times during the year, traffic volumes
were averaged and balanced between the key intersections, as shown in
Figure 3.
Existing Operation
The key intersections were evaluated using techniques provided in
the 2000 Highway Capacity Manual. Using the peak hour traffic shown in
Figure 3, the current peak hour operation is shown in Table 1.
Calculation forms are provided in Appendix B. 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 provided in Appendix B. The
key intersections operate acceptably during both the morning and
afternoon peak hours. Acceptable operation at signalized intersections
during the peak hours in mixed -use districts is defined as level of
service E or better, overall. At unsignalized intersections,
acceptable operation is considered to be at. level of service ,Ffor any
approach leg for an arterial/local intersection.
Pedestrian Facilities
There are pedestrian facilities along Harmony Road adjacent to
the Harmony School and adjacent to developed properties on the south
side of Harmony Road. There are sidewalks on the east side of
Timberline Road. Except for a short segment near Harmony Road, there
are no sidewalks on the west side of Timberline Road. Sidewalks exist
along both sides of Milestone Drive. Sidewalks will be incorporated
within and adjacent to this development.
Bicycle Facilities
Bicycle lanes exist on Harmony. Road and Timberline Road.
Milestone Drive has no bicycle lanes. Bike lanes are not required on
local or connector streets.
Transit Facilities
Currently, Transfort does not serve this area of Fort Collins.

SITE LOCATION Figure 1
II. EXISTING CONDITIONS
The location of the Timberline Village is shown in Figure 1. It
is important that a thorough understanding of the existing conditions be
presented.
Land Use
Land uses in the area are primarily either residential or
commercial/office. Land adjacent to the site is flat (<2% grade) from a
traffic operations perspective. The center of Fort Collins lies to the
northwest of the proposed Timberline Village.
Roads
The primary streets near the Timberline Village site are
Timberline Road, Harmony Road, Milestone Drive, and the Mobile Home Park
Access. Timberline Road is adjacent to the west side of the Timberline
Village site. It is classified as a six -lane arterial on the Fort
Collins Master Street Plan. Currently, Timberline Road has a four -lane
cross section near the Timberline Village site. At the
Harmony/Timberline intersection, Timberline Road has two travel lanes in
each direction, northbound and southbound dual left -turn lanes, and
northbound and southbound right -turn lanes. The Harmony/Timberline
intersection is signalized. At the Timberline/Milestone intersection,
Timberline Road has two travel lanes in each direction, a southbound
left -turn lane, and a northbound right -turn lane. The existing speed
limit in this area is 40 mph.
Harmony Road is adjcent to the south side of the Timberline
Village site. It is an east -west street designated as a six -lane
arterial street on the Fort Collins Master Street Plan. Currently, it
has a four -lane cross section with appropriate auxiliary lanes. At the
Harmony/Timberline intersection, Harmony Road has two travel lanes in
each direction, eastbound and westbound dual left -turn lanes, and
eastbound and westbound right -turn lanes. The existing approach speed
limit in this area is 45 mph.
Milestone Drive is to the north of the Timberline Village site.
It is an east -west street designated as a local street on the Fort
Collins Master Street Plan. Currently, it has a two-lane local street
cross section near the site. The Timberline/Milestone intersection has
stop sign control on Milestone Drive.
The Mobile Home Park (MHP) Access intersects with Harmony Road
east of the Timberline Village site. Current site plans do not show a
connection to the MHP Access. If unacceptable operation occurred at the
Timberline/Milestone intersection, a connection to the MHP Access would
provide the ability to exit the Timberline Village site to eastbound
Harmony Road.

I. INTRODUCTION
This transportation impact study addresses the capacity,
geometric, and control requirements at and near the proposed development
of the Timberline Village. The proposed Timberline Village site is
located in the northeast quadrant of the Harmony/Timberline intersection
in Fort Collins, Colorado.
During the course of the analysis, numerous contacts were made
with the project developer (Miller/Weingarten), the project planning
consultant (Cityscape Urban Design), the project engineering consultant
(JR Engineering), the Fort Collins Traffic Engineering staff, and the
Fort Collins Transportation Planning staff. This study generally
conforms to the format set forth in the Fort Collins transportation
impact study guidelines contained in the "Larimer County Urban Area
Street Standards." A Base Assumptions Form and related information are
provided in Appendix A. 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.
