Ridge Drive and Boardwalk. Drive intersection in Fort Collins, Colorado is proposing an expansion of their existing site. The project is anticipated to include an increase in overall gross leasable area of approximately 30,000 square feet from 99,810 square feet to 130,383 square feet. It is expected that expansion of the existing site would be completed in late 2004. Analysis was therefore completed for the 2005 short term horizon as well as the 2020 long-term horizon as requested by the City of Fort Collins. The purpose of this study is to provide an update given that this project is an expansion. Specifically, this study identifies traffic generation characteristics, identifies potential traffic related impacts on the local. street system, and develops mitigation measures required for identified impacts. The City of Fort Collins identified two key intersections for evaluation in this study. These include the intersections of Boardwalk Drive with both Harmony Road and Oak Ridge Drive. In addition; both access locations along Boardwalk Drive and the access along Oak Ridge Drive were evaluated to provide an overall site analysis. Interstate 25 (I-25) and State Highway 287 (SH-287) will continue to provide regional access to rthe project development. Boardwalk Drive will provide primary access to the site. Direct access to the project is currently provided from two full movement driveways along Boardwalk. Drive and a full movement driveway along Oak. Ridge Drive, to be relocated approximately 50 feet west of the existing access, approximately 120 feet from the intersection of Oak Ridge Drive and Boardwalk Drive. The expansion of the existing Sams Club is expected to generate approximately 116 PM peak hour and 197 Saturday peak hour of the generator driveway vehicle trips. Distribution of site traffic on the street system was based on the area street system characteristics, existing traffic patterns, anticipated surrounding development areas, and the existing access system for the Kimley-Horn and Associates, Inc. 067811007/Sam's Club Expansion, Fort Collins Page 1 project. Assignment of the project traffic was based upon the trip generation described previously and the distribution developed. Based on the analysis presented in this report, Kimley-Horn believes the proposed Sams Club expansion will be successfully incorporated into the roadway network. The proposed project development and expected traffic volumes resulted in the following recommendations:. • Improvements required to the intersection of Harmony Road with Boardwalk Drive to meet acceptable level of service in the long term horizon of 2020 would include additional through lane capacity on Harmony Road and dual left turn lanes on the northbound and southbound approaches to the intersection. It is recommended that volumes at this intersection be monitored to determine the timing of intersection improvements that may be warranted. It is important to recognize that these improvements were found to be required with only the growth expected for background traffic and without the addition of expansion project traffic. • An improvement to the. Harmony Road/Boardwalk Drive intersection in the short term may include striping improvements to designate side -by -side left turns along Boardwalk Drive between Harmony Road and the north project driveway. It is believed that sufficient right of way exists along Boardwalk Drive for this improvement. This modification will increase the storage capacity for the northbound to westbound left turning vehicles at the intersection of Harmony Road with Boardwalk Drive and the southbound to eastbound left turning vehicles at the- north access driveway along Boardwalk Drive. • It is recommended that signs be. installed at the driveway intersection location so that a potential northbound queue of vehicles does not block the intersection of the north access driveway along Boardwalk Drive. Kimley-Horn and Associates; Inc. 067811007/Sam's Club Expansion; Fort Collins Page 2 o All on -site and off=site signing and striping improvements should be incorporated into the Civil Drawings, and conform to City of Fort Collins standards, as well as the Manual on Uniform Traffic Control Devices 2000 (MUTCD). r Kimley-Horn and Associates, Inc. 067811007/Sam's Club Expansion, Fort Collins Page 3 2.0 INTRODUCTION Kimley-Horn and Associates, Inc. (Kimley-Horn) has prepared this report to document the results of a Traffic Impact Study of future traffic conditions associated with the proposed expansion of the existing Sam's Club located south of Harmony Road on the northeast corner of the Oak Ridge Drive and Boardwalk Drive intersection in Fort Collins, Colorado. The vicinity map illustrating the project location is shown in Figure 1. The purpose of this study is to provide an update given that this project is an expansion. Specifically, this study identifies traffic generation characteristics, identifies potential traffic related impacts on the local street system, and develops mitigation measures required for identified impacts. The City of Fort Collins has identified two off -site. key intersections for evaluation in this study. These include the intersections of Boardwalk Drive with both Harmony Road and Oak Ridge Drive. In addition, the project access locations have been studied as requested.. Both access locations along Boardwalk Drive and the access along Oak. Ridge Drive were evaluated to provide an overall site analysis. The specifics pertaining to the requirements of this traffic .study are provided on the Transportation Impact Study Base Assumptions Form provided in Appendix A. The project is anticipated to include an increase in overall gross leasable area of approximately 30,000 square feet from 09,810 square feet to 130,383 square feet. The expansion is expected to be completed in late 2004. Therefore, analysis has been completed for the 2005 short term horizon as well as the 2020 long-term horizon, per City of Fort Collins requirements. The current site plan illustrating development uses and proposed access locations. is shown in Appendix B. Kimley-Horn and Associates, Inc. 067811007/Sarn's Club Expansion, Fort Collins Page 4 No Text 3.0 EXISTING AND FUTURE CONDITIONS 3.1 Existing and Future Roadway Network The project location is along the east side of Boardwalk Drive between Harmony Road and Oak Ridge Drive. Harmony Road carries two through lanes in each direction. Adjacent to the project site, this roadway has a 45-mile per hour speed limit and a grass median. The existing intersection with Boardwalk Drive is signalized. Boardwalk Drive carries a single through lane in each direction adjacent to the project site. The speed limit along this street is 30 miles per hour. The existing intersection of Boardwalk Drive with Oak Ridge Drive is two-way stop controlled along Oak Ridge Drive. Oak Ridge Drive carries one through lane in each direction. Access is currently provided via two full movement driveways along Boardwalk Drive and a full movement driveway along Oak Ridge Drive. Future access is expected to remain the same, except the full movement access along Oak Ridge Drive is proposed to be relocated approximately 50 feet west of the existing access to accommodate the proposed building expansion. This would place this driveway location at approximately 120 feet from the intersection of Oak Ridge Drive and Boardwalk Drive. The existing laneage and control at the intersections is shown in Figure 2. 3.2 Existing Traffic Volumes Existing peak hour turning movement counts were conducted at the existing study intersections of Boardwalk Drive with Harmony Road and Oak Ridge Drive along with the existing northernmost access along Boardwalk Drive on Tuesday, June 3, 2003; and Saturday, June 7, 2003. These counts were conducted during the weekday PM peak hour of adjacent street traffic and Saturday peak hour of the generator in 15-minute intervals from 4:00 PM to 6;00 PM on Tuesday and 1:00 PM to 3:00 PM on Saturday. These volumes are shown in Figure 3 with the count sheets provided in Appendix C. A recent parking study conducted by Wal-Mart stores nationwide found the maximum parking requirements on Saturdays occurred at approximately 2:00 PM. Therefore, counts were conducted between 1:00 PM and 3:00 PM to best capture arrivals and departures during the peak hour of the generator on Saturday.

This growth rate was provided by the City of Fort Collins and reflects future growth projections in the project vicinity. Project PM peak hour traffic from the Bank One Traffic Impact Study completed by Eugene G. Coppola, P.E. in May 2001 were also added to these traffic volumes as this development is expected to be completed prior to 2005 to obtain background traffic volumes at the key intersections. Since this study did not include Saturday afternoon peak hour traffic volumes, only the PM peak hour volumes were added. It could be assumed that this bank would not be open on Saturday afternoons between 1:00 PM and 3:00 PM. The 2005 background traffic estimates are shown in Figure 4. The 2020 background traffic estimates are shown in Figure 5. Kimley-Horn and Associates, Inc.

Rates and equations are applied to the proposed land use to estimate traffic generated by the development during a specific time interval. The acknowledged source for trip generation rates is the current edition of the Trip Generation Report' published by the Institute of Transportation Engineers (ITE). ITE has established trip rates in nationwide studies of similar land uses. For this study, Kimley-Horn used the ITE Trip Generation Report average rate equations that apply to Discount Club (861) for traffic associated with the development. The expansion of the Sams Club is expected to generate an additional 116 PM peak hour and 197 Saturday peak hour of the generator driveway vehicle trips. Table .1 surrunarizes the estimated driveway -traffic generation for the existing development, the proposed development, and the net new driveway vehicle trips resulting from the expansion. The trip generation worksheets are included in Appendix D. These calculations illustrate the average rates used, directional distribution of trips, and number of daily trips. 1 Institute of Transportation Engineers, Trip Generation: An Information Report, Sixth Edition, Washington DC,1997.

The directional distribution of traffic is a means to quantify the percentage of g e site .from a given direction and departs the site in the site -generated traffic that approaches th same direction. Kimley-Horn developed trip distribution estimates based on the above factors. Figure 6 illustrates the expected project trip distribution. Traffic assignment was obtained by applying the distribution to the estimated traffic generation. The traffic assignment is shown in Figure 7. 4.3 Total Background Plus Project Traffic Site traffic volumes were added to the background volumes to represent estimated traffic conditions for the short term 2005 and long term 2020 horizons. These total traffic volumes are illustrated for the 2005 and 2020 horizons in Figures 8 and 9, respectively. Kimley-Horn and Associates, Inc.

Study area intersections were analyzed based on average total delay analysis for signalized and unsignalized intersections. Under the unsignalized analysis, the level of service (LOS) for a two-way stop controlled intersection is determined by the computed or measured control delay and is defined for each minor movement. Level of service for a two-way stop -controlled intersection is not defined for the intersection as a whole. Levels of service for signalized and defined for each approach and for the intersection. four-way stop controlled intersections are 5.1 Intersection Operations Analysis ter. of Level of Service (LOS); LOS is a qualitative term Capacity analysis results are listed in te describing operating conditions a driver will experience while traveling on a particular street o hi hwa during a specific time interval.

With this improvement, all movements are expected to operate with acceptable level of service in 2005 with the exception of the westbound and eastbound left turns onto Boardwalk Drive. In 2020, the level of service. is expected to continue to worsen based upon expected traffic growth and left turn movements from Boardwalk Drive, with and P g without the addition of project traffic. However, this level of service is currently ex erienced. Left turning vehicles are relatively small from both driveway approaches to Boardwalk Drive (45 eastbound left and 23 westbound left during the PM peak hour). These volum es would not be expected to cause significant traffic problems to the surrounding street network by re -diverting.

It is believed that sufficient right of way exists along le Boardwalk Drive to stripe side -by -side left turn lanes of a single southbound and a sing northbound lane between the northern Boardwalk Drive access driveway and the intersection of Boardwalk Drive along Harmony Road fora short term solution. The Poisson method of uniform arrival based upon a 95thpercentile of exceedance was used to estimate the storage requirements for this signalized intersection based upon a is 120 second cycle length. Using th d. roximately 550 feet of storage will be required in 2005 with the addition of proce .ure a pp project. traffic, with 400 feet of storage available. However, these storage demands are expected to be overstated based upon the protective -permissive signal phasing of the left turn movement; with the respect of the relatively light opposing through volume. For the unsignalized driveway storage length analysis, the AASHTO method of uniform arrival and a two minute it time was used. Using this procedure it is expected that 400 feet of storage will be required wait for traffic entering the northern access driveway. it would be recommended that signs be inst alled at the driveway intersection location so that a potential queue of vehicles would not block this' intersection.

The proposed project development and expected traffic volumes resulted in the following recommendations: • Improvements required to the intersection of Harmony Road with Boardwalk Drive to meet acceptable level of service in the long term horizon of 2020 would include additional through lane capacity on Harmony Road and dual left turn lanes on the northbound and southbound approaches to the intersection. It is recommended that volumes at this intersection be monitored to determine the timing of intersection improvements that may be warranted. It is important to recognize that these improvements were found to be required with only the growth expected for background traffic and without the addition of expansion project traffic. • An improvement to the Harmony .Road/Boardwalk Drive intersection in the short term may include striping improvements to designate side -by -side left turns along Boardwalk Drive between Harmony Road and the north project driveway. It is believed that sufficient right of way exists along Boardwalk Drive for this 'improvement. This modification will increase the storage capacity for the northbound to westbound left turning vehicles at the intersection of Harmony Road with Boardwalk Drive and the southbound to eastbound left turning vehicles at the north access driveway along Boardwalk Drive. • It is recommended that signs be installed at the driveway intersection location so that a potential northbound queue of vehicles does not block the intersection of the north access driveway along Boardwalk Drive.
