The project is now submitting for Final Compliance and through the MA process we did not update the Traffic Access Study. I have discussed this with Bill Fox, and the study looked at the access being both full movement and ¾ movement from Timberline. No traffic from the Substation was included in the study as the traffic is nominal. The Planning Department has asked that the study be resubmitted with the FCP, we would ask that in the interest of time and the project’s budget, that the original study (attached) continue to be used. The only changes of substance are that the site plans show the driveway at the substation, and the name of the project has changed from “Integrated” to “Community”. None of the trip generation or conclusions change from the original report. All of the changes made during the Minor Amendment Process were closely coordinated with everyone at Engineering and Traffic, so we are hopeful that this will be acceptable. Sincerely, Michael Oberlander, PE Project Manager Integrated Recycling Facility Traffic Access Study May 28, 2013 Prepared For: City of Fort Collins Submitted By: Fox Tuttle Transportation Group, LLC P.O. Box 19768 Boulder, CO 80308 (303) 652-3571 Ms. Susie Gordon May 28, 2013 Integrated Recycling Facility Traffic Access Study Page 1 May 28, 2013 Ms. Susie Gordon City of Fort Collins 300 Laporte Avenue, Building B Fort Collins, CO 80522 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.

Ms. Susie Gordon May 28, 2013 Integrated Recycling Facility Traffic Access Study Page 4 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.

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.

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.
