HomeMy WebLinkAboutGLOBAL VILLAGE ACADEMY - SITE PLAN ADVISORY REVIEW - SPA130007 - SUBMITTAL DOCUMENTS - ROUND 1 - TRAFFIC STUDYIV. CONCLUSIONS
This study assessed the impacts of the Global Village Academy on the street
system in the vicinity of the proposed development in the short range (2019) future. As a
result of this analysis, the following is concluded:
- The development of the Global Village Academy is feasible from a traffic
engineering standpoint. The Global Village Academy will generate approximately
1118 daily trip ends, 367 morning peak hour trip ends, and 244 afternoon peak
hour trip ends.
- The Taft Hill/Horsetooth, Taft Hill/Bronson, Horsetooth/Silver Trails, and
Bronson/Silver Oaks intersections are currently operating acceptably. .
- The Taft HiIUHorsetooth intersection is currently signalized. Other key intersections
do not meet signal spacing requirements or volume warrants.
- In the short range (2019) future, given development of the Global Village Academy
and an increase in background traffic, the Taft Hill/Horsetooth, Taft Hill/Bronson,
Horsetooth/Silver Trails, Bronson/Silver Oaks -Site Access, and Silver trails/Site
Access intersections will operate acceptably with existing control and geometry.
- The short range (2019) geometry is shown in Figure 10. A southbound right -turn
lane is required at the Taft Hill/Bronson intersection with the existing peak hour
traffic. A northbound right -turn lane is required at the Taft Hill/Horsetooth
intersection with existing peak hour traffic. Global Village Academy adds no traffic
to this movement and the Taft Hill/Horsetooth intersection operates- acceptable
without it. Typically, when turn lanes are shown to be required based on volumes
and do not exist, they are not built unless the operation at the subject intersection
is determined to be unacceptable. The subject intersections operate acceptably.
- Acceptable level of service is achieved for pedestrian, bicycle, and transit modes
based upon the measures in the multi -modal transportation guidelines and future
improvements to the street system in the area.
- Iftwhen the Global Village Academy proposes an expansion, a new transportation
impact study will be required.

Typically the afternoon pick-up period is the most problematic with regard to on -
site circulation, because loading of each vehicle takes longer than unloading. Recent
traffic volume data was collected at a similar school. The data was collected in five
minute increments. Parents arrived 35-40 minutes prior to the dismissal bell. The data
indicates that fifty-five percent of the parent vehicles arrived prior to the dismissal bell.
This creates a vehicle queue prior to the dismissal bell. Based upon this data and the
assumption that 20 percent of the inbound trip generation will be park/walk vehicles,
Table 5 displays the Global Village Academy afternoon peak hour arrivals and
departures in five minute increments using the parking lot pick-up system. In the five
minute increment prior to the dismissal bell, the queue is 51 vehicles in the parking lot.
As shown in Figure 11, this queue can be accommodated within the parking lot
circulation system, with no impact to Bronson Street or Silver Trails Drive. In five
minute increment following the dismissal bell, eight more vehicles join the inbound
queue and nine vehicles leave the site, resulting in a vehicle queue of 50 vehicles within
the parking lot. As vehicles begin to release, the queue in the following series of five
minute increments can be accommodated within the parking lot with no impact to Silver
Trails Drive or Bronson Street. There is usually a "learning period" to understand the
circulation system. The first few days of school are not indicative of the planned
system. In order for the circulation system to be successful, it must be enforced by the
school administration. It is important that the on -site circulation system be monitored for
efficiency and adjusted/modified if necessary.
Pedestrian Level of Service
Appendix F shows a map of the area that is within 1320 feet of the Global Village
Academy development. There are four pedestrian destinations within 1320 feet of the
Global Village Academy development. These are: 1) the residential area to the west of
the site, 2) the residential area to the east of the site, 3) the residential area to the south
of the site, and 4) the residential area to the southeast of the site. This site is in an area
type termed "school walking area." The minimum level of service for "school walking
area" is B, except for Visual Interest and Amenity which is C. Acceptable pedestrian
level of service will be achieved for all pedestrian destinations. The Pedestrian LOS
Worksheet is provided in Appendix F.
Bicycle Level of Service
There are no bicycle destinations within 1320 feet of the Global Village Academy
development. The bicycle level of service is acceptable.
Transit Level of Service
This area of Fort Collins is served by Transfort Route 6. This route has a transit
stop at the Taft Hill/Horsetooth intersection, which is adjacent to this site.

Using the traffic volumes shown in Figure 9, the Taft Hill/Horsetooth, Taft
Hill/Bronson, Horsetooth/Silver Trails, Bronson/Silver Oaks -Site Access, and Silver
Trails/Site Access intersections will operate in the short range (2019) total traffic future as
indicated in Table 4 with the existing geometry. Calculation forms for these analyses are
provided in Appendix E. The key intersections will operate acceptably. At the Taft
Hill/Bronson intersection, the calculated delay for the morning and afternoon peak hour
eastbound approach will be commensurate with level of service F and the morning peak
hour westbound approach will be commensurate with level of service E. This is
considered to be normal during the peak hours at stop sign controlled intersections along
arterial streets. The Taft Hill/Bronson intersection was analyzed with and without the
southbound right -turn lane with the short range (2019) total peak hour traffic. There is no
change in the level of service with or without the southbound right -turn lane at the Taft
Hill/Bronson intersection.
Geometry
Figure 10 shows a schematic of the short range (2019) geometry. A southbound
right -turn lane is required at the Taft Hill/Bronson intersection. This is required with the
existing peak hour traffic volumes. There is no change in the level of service with the
added right -turn lane at the Taft HiIVBronson intersection. It was observed that with the
lane drop at the Taft Hill/Horsetooth intersection through vehicles are typically in the left
through lane prior to the Taft Hill/Bronson intersection. Most vehicles in the right
through lane are vehicles that will turn right at the Taft Hill/Bronson or Taft
Hill/Horsetooth intersections. A northbound right -turn lane is required at the Taft
Hill/Horsetooth intersection. However, Global Village Academy adds no traffic to this
movement and the Taft Hill/Horsetooth intersection operates acceptably. As mentioned
earlier, when existing volumes warrant the subject right -turn lanes, but the intersections
operate acceptably without those lanes, they are typically not constructed. It is
recommended that the right -turn lanes not be built at this time. The need for an eastbound
left -turn lane at the Horsetooth/Silver Trails was evaluated. Using LCUASS, Figure,8-1, an
eastbound left -turn lane will not be required at this intersection.
Circulation/Queue Analysis
The parking lot is designed to provide a drop-off/pick-up area on the south side of
the school building. Due to the site circulation system, there is an on -site intersection
which will have both entering and exiting parent vehicles going through it. This
intersection should be signed DO NOT BLOCK. The exiting parent vehicles must be
allowed to exit from the front of the school in order for the drop-off/pick-up system to
operate efficiently. This must be enforced by the school administration. As is common
at many schools, some parents (particular those with children in the lower grades) will
park and walk their children into/out of the school. These parents will utilize the spaces
in the parking lot. This factor has a bearing on how many parent vehicles need to be
accommodated in the parking lot drop-off/pick-up circulation system.

Background Traffic Projections
Figure 7 shows the short range (2019) background traffic projections.
Background traffic projections for the short range future horizon were obtained by
reviewing the North Front Range Regional Transportation Plan and various traffic
studies prepared for this area of Fort Collins. Based upon these sources, it was
determined that traffic volumes would increase by approximately 1.5% per year in the
short range future.
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 generation
and trip distribution process. It is recommended that Global Village Academy request
parents (exiting the site) going to the north on Taft Hill Avenue use the signal at the Taft
Hill/Horsetooth intersection. This route would be the safest and most efficient to go north
on Taft Hill Road. However, some parents may choose not to do this. Therefore, the
traffic assignment shows a portion making a left turn at the Taft Hill/Bronson intersection.
The site traffic assignment shows that a portion of the entering traffic (estimated at 15
percent) from the east and south will utilize the Silver Trails Drive access. Figure 8 shows
the site generated peak hour traffic assignment. Figure 9 shows the short range (2019)
total (site plus background) peak hour traffic.
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. The Taft
Hill/Horsetooth intersection is currently signalized. Other key intersections do not meet
signal spacing requirements or volume warrants, and will not be signalized.
Operation Analysis
Capacity analyses were performed at the Taft Hill/Horsetooth, Taft Hill/Bronson,
Horsetooth/Silver Trails, Bronson/Silver Oaks, and Silver Trails/Site Access intersections.
The operations analyses were conducted for the short range future, reflecting a year 2019
condition.
Using the traffic volumes shown in Figure 7, the Taft Hill/Horsetooth, Taft
Hill/Bronson, Horsetooth/Silver Trails, and Bronson/Silver Oaks intersections will operate
in the short range (2019) background traffic future as indicated in Table 3 with the existing
geometry. Calculation forms for these analyses are provided in Appendix D. The key
intersections will operate acceptably. At the Taft Hill/Bronson intersection, the calculated
delay for the morning and afternoon peak hour eastbound approach will be commensurate
with level of service E and F, respectively. This is considered to be normal during the
peak hours at stop sign controlled intersections along arterial streets.

III. PROPOSED DEVELOPMENT
Figure 5 shows a site plan of the Global Village Academy. The Global Village
Academy staff indicated that this school will have a total of 540 students in 5 years
(Phase 1). The short range analysis (Year 2019) includes development of the Global
Village Academy and an appropriate increase in background traffic due to normal
growth and other potential developments in the area. Since this is an intermediate level
transportation impact study, a long range analysis is not required. The site plan shows
that the Global Village Academy accesses Silver Trails Drive and Bronson Street.
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 for Private School K-8
(Code 5348) in Trip Generation, 9th Edition, ITE fits the description of the Global Village
Academy. 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. Global Village
Academy currently has three buses and plans to increase to four buses. Global Village
Academy, also, has a high carpool ratio. Based on this information a reduction of 0.25
was taken for busing and carpooling. The trip generation of the Global Village Academy
resulted in 1118 daily trip ends, 367 morning peak hour trip ends, and 244 afternoon peak
hour trip ends.

Trip Distribution
Trip distribution for the Global Village Academy was based on existing/future
travel patterns, land uses in the area, consideration of trip attractions/productions in the
area, and engineering judgment. Figure 6 shows the trip distribution for the short range
(2019) analysis future. The trip distribution was agreed to by City of Fort Collins staff in
the scoping discussions.

Village Academy site is in an area termed "low density mixed use residential." In areas
termed "low density mixed use residential," acceptable operation at signalized
intersections during the peak hours is defined as level of service D or better. At
unsignalized arterial/local intersections, acceptable operation is considered to be at
level of service F for any approach leg. In such areas, it is expected that there would be
substantial delays to the minor street movements 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. A
northbound right -turn lane at the Taft Hill/Horsetooth intersection is required with
existing traffic. A southbound right -turn lane at the Taft Hill/Bronson intersection is
required with existing traffic. It was observed that with the lane drop at the Taft
Hill/Horsetooth intersection through vehicles are typically in the left through lane north of
the Taft Hill/Bronson intersection. Typically, when turn lanes are shown to be required
based on volumes and do not exist, they are not built unless the operation at the subject
intersection is determined to be unacceptable. The subject intersections operate
acceptably.
Pedestrian Facilities
There are sidewalks along both sides of Taft Hill Road, except along this site.
There are sidewalks along both sides of Bronson Street, Silver Trails Drive, and Silver
Oaks Drive. Horsetooth Road has sidewalk along both sides of the street east of Silver
Trails Drive.
Bicycle Facilities
There are bicycle lanes along Taft Hill Road and Horsetooth Road.
Transit Facilities
Currently, this area of Fort Collins is served by Transfort Route 6. It operates
along Taft Hill Road and Horsetooth Road with a bus stop at the Taft Hill/Horsetooth
intersection.

Currently, Silver Oaks Drive has a two-lane cross section. At the Bronson/Silver Oaks
intersection, Silver Oaks Drive has all movements combined into a single lane. The
posted speed limit in this area of Silver Oaks Drive is 25 mph.
Existing Traffic
Recent peak hour traffic volumes are shown in Figure 3. The traffic counts at the
Taft Hill/Horsetooth, Taft Hill/Bronson, Horsetooth/Silver Trails, and Bronson/Silver
Oaks intersections were obtained in November 2013. Raw traffic count data is provided
in Appendix B. Since the traffic counts were done on different days, the intersection
counts were adjusted/balanced. Figure 4 shows the adjusted/balanced recent peak
hour traffic volumes.
Existing Operation
The Taft Hill/Horsetooth, Taft Hill/Bronson, Horsetooth/Silver Trails, and
Bronson/Silver Oaks intersections were evaluated and the peak hour operation is
displayed in Table 1. Calculation forms are provided in Appendix C. The key
intersections are currently operating acceptably with existing control and geometry in
the morning and school dismissal peak hours. At the Taft Hill/Bronson intersection, the
calculated delay for the morning and afternoon peak hour eastbound approach is
commensurate with level of service E. The intersections were evaluated using
techniques provided in the 2000 Highway Capacity Manual and 2010 Highway Capacity
Manual. A description of level of service for signalized and unsignalized intersections
from the 2010 Highway Capacity Manual and a table showing the Fort Collins Motor
Vehicle LOS Standards (Intersections) are also provided in Appendix C. The Global

II. EXISTING CONDITIONS
The location of the proposed Global Village Academy 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 residential. There are residential uses to the
west, north, east, and south of the site. There is a school (Olander) and a park (Spring
Canyon Park) west of the site. The center of Fort Collins lies to the northeast of the
proposed Global Village Academy. .
Streets
The primary streets near the proposed Global Village Academy site are Taft Hill
Road, Horsetooth Road, Bronson Street, and Silver Trails Drive. Figure 2 shows a
schematic of the existing geometry at the Taft _Hill/Horsetooth, Horsetooth/Silver Trails,
Taft Hill/Bronson, and Bronson/Silver Oaks intersections.
Taft Hill Road is east of (adjacent to) the proposed Global Village Academy site.
It is a north -south street classified as a four -lane arterial according to the Fort Collins
Master Street Plan. Currently, Taft Hill Road has a four -lane cross section, north of
Horsetooth Road and a two-lane cross section, south of Horsetooth Road. At the Taft
Hill/Horsetooth intersection, Taft Hill Road has a northbound and a southbound left -turn
lane, a through lane in each direction, a northbound through/right-turn lane, and a
southbound right -turn lane. At the Taft Hill/Bronson intersection, Taft Hill Road has a
northbound and a southbound left -turn lane and two through lanes in each direction.
The Taft Hill/Horsetooth intersection has signal control. The Taft Hill/Bronson
intersection has stop sign control on Bronson Street. The posted speed limit in this area
of Taft Hill Road is 40 mph.
Horsetooth Road is south of (adjacent to) the proposed Global Village Academy
site. It is an east -west street classified as a two-lane collector, west of Taft Hill Road
and a four -lane arterial, east of Taft Hill Road according to the Fort Collins Master Street
Plan. Currently, Horsetooth Road has a two-lane cross section. At the Taft
Hill/Horsetooth intersection, Horsetooth Road has an eastbound and a westbound left -
turn lane, a through lane in each direction, and an eastbound and westbound right -turn
lane. At the Horsetooth/Silver Trails intersection, Horsetooth Road has all movements
combined into a single lane. The Horsetooth/Silver Trails intersection has stop sign
control on Silver Trails Drive. The posted speed limit in this area of Horsetooth Road is
35 mph, west of Taft Hill Road and 40 mph, east of Taft Hill Road.

I. INTRODUCTION
This intermediate transportation impact study (TIS) addresses the capacity,
geometric, and control requirements at and near the proposed Global Village Academy.
The proposed Global Village Academy is to be located in the northwest quadrant of the
Taft Hill/Horsetooth intersection in Fort Collins, Colorado.
During the course of the analysis, numerous contacts were made with the owner's
(Global Village Academy) and the City of Fort Collins Traffic Engineering Staff. The
Transportation Impact Study Base Assumptions form and related documents are provided
in Appendix A. This study generally conforms to the format set forth in the Fort Collins TIS
Guidelines in the "Larimer County Urban Area Street Standards" (LCUASS). Since this is
a school, it was determined that the peak hours should be the typical morning peak hour
and the school dismissal time (2:30pm-3:45pm). The study involved the following steps:
- Collect physical, traffic, and development data;
- Perform trip generation, trip distribution, and trip assignment;
- Determine peak hour traffic volumes;
- Conduct capacity and operational level of service analyses on key intersections;
- Analyze signal warrants;
- Conduct level of service evaluation of pedestrian, bicycle, and transit modes of
transportation;
- Conduct on -site queuing analysis.
