RE: Integrated Recycling Facility Traffic Access Study
Dear Ms. Gordon:
At your request I have prepared a traffic access study for the proposed Integrated Recycling
Facility to be located on the west side of Timberline Road approximately ¼ mile south of
Prospect Street in Fort Collins. Figure 1 includes an illustration of the site vicinity. In the
process of completing this study I have:
discussed the proposed site design and uses with you and members of the project team;
reviewed plans for the new facility;
discussed traffic access issues and study scope with City of Fort Collins Traffic
Engineering staff;
reviewed recent and historic traffic count information at the existing recycle facility on
Riverside Avenue;
reviewed trip generation and access information for a similar recycling facility in Boulder,
CO;
procured AM and PM peak hour traffic counts at the adjacent industrial driveway just
south of the site;
reviewed existing and projected Year 2035 traffic information at the Timberline
Road/Prospect Street intersection;
projected the daily and peak hour traffic that will be added to area roadways by the
Integrated Recycling Facility;
evaluated the impacts of this additional traffic on the site access intersection on
Timberline Road;
and, recommended access intersection configuration.
Findings and conclusions of this evaluation are summarized by topic as follows:
Site Use and Access
The proposed new Integrated Recycling Facility will be located on the west side of Timberline
Road approximately ¼ mile south of Prospect Street in Fort Collins, CO. This site is just south
of an electrical substation, and just north of an industrial site. As currently proposed, the
Integrated Recycling Facility will include:
Ms. Susie Gordon May 28, 2013
Integrated Recycling Facility Traffic Access Study Page 2
relocated recycling facility (Rivendell Recycling Center) that is currently on Riverside
Avenue just north of Prospect Street – open 7 days per week – free to the public;
a new recycling space for “hard to recycle” materials – open weekdays during business
hours – fee to be collected by a small staff;
a new yard waste drop-off facility – open 7 days per week;
and related City recycling operations – open on weekdays.
It is my understanding that the site will be configured such that different areas may be open 7
days per week and some areas will be open only on weekdays during the business day.
As proposed, the site will share the existing access drive onto Timberline Road that currently
serves the electrical substation. Figure 2 includes a site plan for this recycling facility.
In this vicinity Timberline Road has two through lanes in each direction and a painted center
two-way left turn lane.
Existing and Projected Background Traffic Conditions
Based on recent peak hour traffic counts at area intersections it is estimated that Timberline
Road currently carries approximately 28,000 vehicles per day in the vicinity of this site. Figure 3
includes recent peak hour traffic counts from the industrial driveway intersection just south of
the project site. It has been assumed that there is little or no existing traffic accessing the
electrical substation driveway (locked gate) during the AM and PM peak traffic hours on
Timberline Road.
Future traffic projections from the City’s travel model indicate that background traffic on
Timberline Road in this area will increase by approximately 12% by the year 2035.
Trip Generation, Distribution and Assignment
An estimate of daily and peak hour traffic that will access the new Integrated Recycling Facility
has been made based on our understanding of the proposed site uses, historic traffic access
patterns at the Rivendell site, and our experience with recycling facilities in another community
of similar size to Fort Collins. The results are detailed in Table 1 and summarized as follows:
On a daily basis the amount of traffic accessing the new facility will be approximately
double the traffic that currently accesses the Rivendell site. This equates to 900 one-
way vehicle trips per day on weekdays.
Due to the type of new uses at the Integrated Recycling Facility, the peak hour traffic
access is not projected to double the existing traffic at the Rivendell site. Rather, it is
projected that the AM and PM peak hour traffic (while Timberline traffic is highest) will
increase by approximately 50% to 30 trips per hour. This projection assumes that
citizens are not as likely to drop off yard waste and hard to recycle materials on the way
to and from work as they might be to drop off conventional recyclables.
Ms. Susie Gordon May 28, 2013
Integrated Recycling Facility Traffic Access Study Page 3
The weekday hourly traffic accessing the new facility will be highest mid-day, with
approximately 120 vehicle trips per hour (while Timberline traffic is not at its peak).
Saturday traffic will likely be the highest, with a peak of over 130 trips per hour.
It is our understanding that there will not be “site owned” trucks operating from the site,
and recycled materials will be hauled off by outside trucks. It is likely that these trucks
will avoid the AM and PM weekday peak hours when servicing the site.
The new facility will include a small staff (2 to 3 employees) who will likely access the
site during weekday peak hours.
All trips accessing the site will utilize Timberline Road. It is estimated, based on the site’s
location relative to the entire community and the roadway network in the area, that 45% of the
traffic will be to/from the north on Timberline and 55% will be to/from the south. This access
pattern is illustrated on Figure 4, and for the moment assumes that the site driveway will have
full turning access.
Using the trip generation and trip distribution patterns described above, the peak hour site
access traffic is illustrated on Figure 5. Again, assuming full access, it is projected that there will
be less than 10 vehicles per hour in any one direction accessing the site.
Near Term Traffic Access
If full turning access is provided, the projected near term peak hour traffic at the site driveway is
illustrated on Figure 6. The projected peak hour level of service (LOS) at the site driveway has
been calculated using procedures defined in the Highway Capacity Manual, assuming stop sign
control on the site exit. The results are included in Table 1 below, and detailed LOS calculation
reports are attached. Also attached is a description of the traffic conditions associated with
each LOS letter grade.

Year 2035 Traffic Access
By the year 2035 it has been projected that the background traffic on Timberline Road has
increased by approximately 12 percent. We have also projected that the site access traffic
increases by 25% by this time. It has also been assumed that Timberline has been widened to
include 3 through lanes in each direction. The resulting traffic at the site access intersection
(assuming full movement access allowed) is illustrated in Figure 7.
Again, the site access LOS was calculated with full movement access and ¾ access and the
results are detailed in Table 1. As with the near term results, it is projected that the outbound
left turn will operate at LOS F with significant delay if full turning access is allowed. If the
driveway is restricted to a ¾ access, all turning movements will operate acceptably in the B/C
range.
Conclusions and Recommendations
This traffic study has projected and evaluated the traffic that will access the new Integrated
Recycling Facility on Timberline Road in Fort Collins. Significant observations, conclusions, and
recommendations include:
The new recycling facility is projected to generate approximately 900 trips per day on
weekdays. This is approximately double the existing traffic generated by the Rivendell
site currently.
On weekdays during the AM and PM peak hours when traffic on Timberline Road is
highest, the recycling facility will generate approximately 30 site access trips.
There will be minimal truck traffic accessing the site during the AM and PM peak hours.
The daily traffic accessing the site will likely be highest on Saturdays when background
traffic on Timberline Road is not at its peak. The Saturday peak hour traffic is projected
to be just over one inbound and one outbound vehicle per minute during the highest
hour.
If full movement access is maintained at the site driveway, the outbound left turning
traffic will experience LOS F during the weekday AM and PM peak hours.
If the site driveway is restricted to ¾ access (right in, right out, and left in only) then all
access traffic will operate well in the LOS B/C range during peak hours.
Timberline Road will be able to easily accommodate the relatively low level of traffic
generated by this Integrated Recycling Facility.
The grid of arterial roadways in the area will be able to accommodate diverted traffic if
the site access driveway is restricted to a ¾ access and all outbound traffic is forced to
turn right onto southbound Timberline Road.
Given the projected congestion for the left turning outbound traffic, and the potential for
safety issues (vehicles exiting with trailers, etc.) we recommend that the site driveway be
configured as a ¾ access with right in, right out, and left in access only. This
intersection access control should be implemented with the construction of a raised
median in Timberline Road that prevents left turns out of the site.
I hope this information is helpful as you continue planning for the new Integrated Recycling
Facility in Fort Collins. Please let me know if you have any questions.

Notes:
1. Assume existing recycle facility will have similar useage as existing site once relocated to new facility.
2. Assume that the site will not own any trucks and all materials will be hauled off by off-site trucking.
3. Assume that most if not all truck access trips will avoid the weekday AM and PM peak hours of the adjacent road system.
4. It is projected that the new facility will approximately double the daily traffic as exists at the current facility. However, it is projected that the Hard TO Recycle trips and the
Yard Waste drop off trips will typically be
outside of the AM and PM peak hours of the day (not as likely to be dropped off on the way to or from work).
5. Trip estimates based on traffic counts at existing facility, estimates of expanded use based on conversations with site operators, and experience with similar facilities in other
communities.

LEVEL OF SERVICE DEFINITIONS
In rating roadway and intersection operating conditions with existing or future traffic
volumes, “Levels of Service” (LOS) A through F are used, with LOS A indicating very good
operation and LOS F indicating poor operation. Levels of service at signalized and
unsignalized intersections are closely associated with vehicle delays experienced in
seconds per vehicle. More complete level of service definitions and delay data for signal
and stop sign controlled intersections are contained in the following table for reference.
Level
of Service
Rating
Delay in seconds per vehicle (a)
Definition
Signalized
Unsignalized
A
0.0 to 10.0
0.0 to 10.0
Low vehicular traffic volumes; primarily free flow operations. Density is
low and vehicles can freely maneuver within the traffic stream. Drivers
are able to maintain their desired speeds with little or no delay.
B
10.1 to 20.0
10.1 to 15.0
Stable vehicular traffic volume flow with potential for some restriction
of operating speeds due to traffic conditions. Vehicle maneuvering is
only slightly restricted. The stopped delays are not bothersome and
drivers are not subject to appreciable tension.
C
20.1 to 35.0
15.1 to 25.0
Stable traffic operations, however the ability for vehicles to maneuver is
more restricted by the increase in traffic volumes. Relatively satisfactory
operating speeds prevail, but adverse signal coordination or longer
vehicle queues cause delays along the corridor.
D
35.1 to 55.0
25.1 to 35.0
Approaching unstable vehicular traffic flow where small increases in
volume could cause substantial delays. Most drivers are restricted in
ability to maneuver and selection of travel speeds due to congestion.
Driver comfort and convenience are low, but tolerable.
E
55.1 to 80.0
35.1 to 50.0
Traffic operations characterized by significant approach delays and
average travel speeds of one‐half to one‐third the free flow speed.
Vehicular flow is unstable and there is potential for stoppages of brief
duration. High signal density, extensive vehicle queuing, or corridor
signal progression/timing are the typical causes of vehicle delays at
signalized corridors.
F
> 80.0
> 50.0
Forced vehicular traffic flow and operations with high approach delays
at critical intersections. Vehicle speeds are reduced substantially and
stoppages may occur for short or long periods of time because of
downstream congestion.
(a) Delay ranges based on 2010 Highway Capacity Manual criteria.

It can be seen in Table 1 that providing full turning movement access with lefts in and out of the
site driveway will result in poor LOS for vehicles turning left out onto Timberline Road in both the
AM and PM peak hours. If a median were constructed to limit the site driveway to a ¾ access
(right in, right out, and left in only), the outbound traffic would operate at LOS A in the AM peak
hour and LOS C in the PM peak hour. The left in traffic would also operate well in the B/C
range.
