CONCLUSIONS This study assessed the potential impacts of constructing the Timber Lakes Business Park north of Prospect Road and on both sides of Timberline Road in Fort Collins, Colorado. As a result of the analysis, the following conclusions were drawn: - The potential impacts of the proposed project were evaluated at the following intersections: Timberline/Drake, Timberline/Prospect, Timberline/SH 14, Prospect/Riverside, Timberline/South Access, and Timberline/North Access. ' - The traffic impact analyses were performed for future Years 2001,nd 2009, a2020. Future background traffic conditions without the project and total traffic conditions with completion of the proposed project were evaluated. - For Year 2001 background and total traffic conditions, the study intersections are projected to operate at acceptable levels of service with the geometric improvements recommended in Figure 13. - For Year 2009 future background and total traffic conditions, the study intersections are projected to operate at acceptable levels of service. A signal will be warranted at the Timberline/North Access intersection. The mid range geometry is shown in Figure 14. - For Year 2020 future background and total traffic conditions, the study intersections are projected to operate at acceptable levels of service. The long range geometry is shown in Figure 15. - Acceptable level of service is achieved for pedestrian, bicycle, and transit modes based upon Fort Collins measures in the multi -modal transportation guidelines. 29 W m 0 N LONG RANGE GEOMETRY 28 Figure 15 r� the Timberline/South Access intersection will experience delays ' commensurate with level of service F. These left -turning vehicles will have the option of utilizing the signal at the Timberline/North Access intersection. The Year 2020 intersection geometry is depicted on Figure 15. ' Pedestrian Level of Service Appendix I contains a map that shows the area within 1320 feet of this site. There are no pedestrian destinations, other than the commercial/ business uses near Prospect Road. When the City continues to ' expand Timberline Road, improvements will be made to the sidewalks along this arterial street. The Timber Lakes Business Park will build sidewalks adjacent to Timberline Road. The level of service determination assumes that future developments and the City of Fort Collins will build their facilities in accordance with Fort Collins standards. This being the case, pedestrian facilities will exist where they currently do not. This is a reasonable assumption. The Pedestrian LOS Worksheet is provided in Appendix I. The minimum level of service for this land use category is C for all measured categories. ' Bicycle Level of Service ' There are no "Priority Destinations" within a quarter mile of the Timber Lakes Business Park. The cross section of Timberline Road has bike lanes. These will be enhanced as Timberline Road is improved in the future. Appendix I contains the Bicycle LOS Worksheet. Transit Level of Service Currently, this area is served by Route 10. The Fort Collins 2015 ' Transit System shows that this area (Prospect Road and Timberline Road) will be served by feeder route service at 30 minute headways. Transit ' level of service will be at D or better. r LJ I I 27 I Table 7 Year 2020 Peak Hour Background Traffic Operation Level of Service Intersection AN PM Timberline/Drake (signal) C C Timberline/Prospect (signal) D D Timberline/SH14 (signal) C C Prospect/Riverside (signal) C C Table 8 Year 2020 Peak Hour Total Traffic Operation Level of Service Intersection am Phi Timberline/Drake (signal) D C Timberline/Prospect (signal) D D Timberline/SH14 (signal) C C Prospect/Riverside (signal) C C Timberline/South Access (stop sign) EB LT/T/RT C C WB LT D F WB T/RT B A NB LT A A SB LT B A OVERALL A A Timberline/North Access (signal) B B 26 O1 0 A N MID RANGE GEOMETRY 25 Figure 14 Table 5 Year 2009 Peak Hour Background Traffic Operation Intersection Timberline/Drake (signal) Timberline/Prospect (signal) Timberline/SH14 (signal) Prospect/Riverside (signal) Level of Service am FM C C C C C C C C Table 6 Year 2009 Peak Hour Total Traffic Operation Intersection Timberline/Drake (signal) Timberline/Prospect (signal) Timberline/SH14 (signal) Prospect/Riverside (signal) Timberline/South Access (stop sign) EB LT/T/RT WB LT WB T/RT NB LT SB LT OVERALL Timberline/North Access (signal) 24 Level of Service AM PM C C D D C C C C B B D E A A A A A A A A B B r m 0 N e SHORT RANGE GEOMETRY 23 Figure 13 Table 3 Year 2001 Peak Hour Background Traffic Operation Intersection Timberline/Drake (signal) Timberline/Prospect (signal) Timberline/SH14 (signal) Prospect/Riverside (signal) Level of Service w P1`4 C C C C C C B B Table 4 Year 2001 Peak Hour Total Traffic Operation Intersection Timberline/Drake (signal) Timberline/Prospect (signal) Timberline/SH14 (signal) Prospect/Riverside (signal) Timberline/South Access (stop sign) EB LT/RT NB LT OVERALL 22 Level of Service AM PM C C C C C C B B B B A A A A VI. TRAFFIC IMPACT ANALYSIS The previous chapter described the development of future traffic forecasts both with and without the proposed project. Intersection capacity analyses are conducted in this chapter for all scenarios to assess the potential impact of the proposed project -generated traffic on the local street system. Traffic Analysis - Year 2001 The peak hour background and total traffic volumes for Year 2001, illustrated on Figures 7 and 10, respectively, were analyzed to determine the intersection delay and corresponding level of service. Tables 3 and 4 summarize the results for the respective Year 2001 background and total traffic conditions. The level of service worksheets for Year 2001 background and total traffic conditions are provided in Appendix C and D, respectively. As indicated in Tables 3 and 4, the traffic movements at each of the study intersections are expected to operate at an acceptable level of service under future traffic conditions for Year 2001. The Year 2001 intersection geometry is depicted on Figure 13. There are geometric improvements recommended at the Timberline/Drake and Timberline/Prospect intersections. Traffic Analysis - Year 2009 The Year 2009 peak hour traffic volumes for background and total traffic conditions (after full build out of Timber Lakes), illustrated on Figures 8 and 11, respectively, were analyzed to determine the intersection delay and corresponding level of service. Tables 5 and 6 summarize the results. Appendix E contains worksheets for Year 2009 background conditions and Appendix F for total traffic conditions. The level of service analyses shown in Tables 5 and 6 indicate that the study intersections will continue to operate at acceptable levels of service for the Year 2009. Westbound left turns at the Timberline/South Access intersection will experience delays commensurate with level of service E. These left -turning vehicles will have the option of utilizing the signal at the Timberline/North Access intersection. The Year 2009 intersection geometry is depicted on Figure 14. There are geometric improvements recommended at the Timberline/Drake, Timberline/Prospect, Timberline/South Access, and Timberline/North Access intersections. Traffic Analysis - Year 2020 The Year 2020 peak hour traffic volumes for background and total traffic conditions, illustrated on Figures 9 and 12, respectively, were analyzed to determine the intersection delay and corresponding level of service. Tables 7 and 8 summarize the results. Appendix G contains worksheets for Year 2020 background conditions and Appendix H for total traffic conditions. The level of service analyses shown in Tables 7 and 8 indicate that the study intersections will continue to operate at acceptable levels of service for the Year 2020.

FUTURE TOTAL TRAFFIC PROJECTIONS The future total traffic projections reflect future traffic conditions with the traffic from the proposed Timber Lakes Business Park project. The future total traffic projections were developed for Years 2001, 2009, and 2020. Total Traffic Year 2001 The total traffic for Year 2001 was developed by adding traffic from the proposed project to the background traffic for Year 2001. The resulting peak hour total traffic projections for Year 2001 are shown on Figure 10. Total Traffic Year 2009 The total traffic for Year 2009 was developed by adding traffic from the proposed project to the background traffic for Year 2009. The resulting peak hour total traffic projections for Year 2009 are shown on Figure 11. Based upon these traffic forecasts, the Timberline/North Access intersection will meet peak hour signal warrants. Total Traffic Year 2020 The total traffic for Year 2020 was developed by adding traffic from the proposed project to the background traffic for Year 2020. The resulting peak hour total traffic projections for Year 2020 are shown on Figure 12. 17 m O HOFFMAN MILL ROAD 1 0 0 0 0 590/535 `* 985/mo J j j -- 50/85 70/30 —' I 1 T 1 1050/1oe5--- o 40/80 --- N N N N 165/120 + 1280/1170 J 1 L 150/220 110 130 910 1470 y o 215/320 m N 17 �- g— 55/60 104 1 4I55 � 5 '535 165/195 215/275 j 65/55 DRAKE 380/235 1 T f 170/200 m 540/525 �o LONG RANGE BACKGROUND PEAK HOUR TRAFFIC (YEAR 2020) 16 AM/PM Rounded to the Nearest 5 Vehicles.

FUTURE BACKGROUND TRAFFIC PROJECTIONS In order to properly evaluate the potential impact of the proposed Timber Lakes Business Park project on the local traffic conditions, future traffic volumes were first estimated for the study area without the project. These future forecasts reflect the growth that is expected from overall development in and around the City of Fort Collins and traffic from other known future projects in the vicinity of the site. Background Traffic Year 2001 The growth reflected in Year 2001 Background Traffic is based on two factors: area wide growth and development, and traffic generated by specific projects located near the study intersections. The overall growth in the study area and the redistribution of traffic was based upon traffic projections provided in the Operational Analysis Timberline Road Extension and State Highway 14, and traffic from Timberline Industrial Park, Spring Creek Center, and Rigden Farm. Appropriate portions of these developments were included in the Year 2001 analysis. The peak hour background traffic for Year 2001 is depicted on Figure 7. Background Traffic Year 2009 Future projections of background traffic for Year 2009 were developed utilizing future traffic projections previously developed for the Timberline Road Extension and adding traffic from assumed future developments. The peak hour background traffic for Year 2009 is depicted on Figure 8. Background Traffic Year 2020 Future projections of background traffic for Year 2020 were developed utilizing future traffic projections previously developed for the Timberline Road Extension and adding traffic from assumed future developments.

PROPOSED DEVELOPMENT The Timber Lakes Business Park is a proposed commercial/industrial/ retail development located in Fort Collins, Colorado. The project site, depicted on Figure 3, is located on the east and west side of Timberline Road to the north of Prospect Road. Direct access to the west site will be from a south access. Direct access to the east site will be from the south access and a north access. Trip Generation Trip generation is important in considering the impact of a development such as this upon the existing and future street system. A compilation of trip generation information, prepared by the Institute of Transportation Engineers (Trip Generation. 6th Edition) was used to project trips that would be generated by the proposed uses at this site. Table 2 shows the trip generation of the proposed project. Land use code 130 (Industrial Park), 710 (Office), and 820 (Retail) was used to estimate the trip generation. As indicated in Table 2, it is anticipated that the project would generate approximately 5255 average daily trips, 551 morning peak hour trips, and 634 afternoon peak hour trips. Trip Distribution The directional distribution of the generated trips was determined for the proposed Timber Lakes Business Park. The distribution was determined based upon a gravity model process, future traffic projections from the Timberline Extension study, and engineering judgment. The trip distribution is provided on Figure 4. 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 distribution process. Figures 5 and 6 show the peak hour site generated traffic for Phase I and full build out of the proposed project, respectively. 7 I service E. Although the intersection operates at level of service D, these particular movements need to be addressed. Pedestrian Facilities According to City criteria, the limit of the pedestrian analysis is 1320 feet. This site is within 1320 feet of open space and other commercial/business park uses. The sidewalk system in the area is sporadic, due to gaps in development activity. These gaps will be closed as development continues. 11 Bicycle Facilities The only defined bicycle facilities on any of the area streets within 1320 feet of the site are along Timberline Road. The Spring Creek and Poudre River bicycle trails are to the south, east and north of the site. ITransit Facilities Transfort current serves this area of Fort Collins with Route 10. Route 10 provides 60 minute service with a stop near the Prospect/ Timberline intersection.

EXISTING CONDITIONS The location of the proposed Timber Lakes Business Park is shown on Figure 1. It is important that a thorough understanding of the existing conditions be presented. Land Use Land uses in the area are predominantly industrial/commercial. North of the site is undeveloped land. South and east of the site is industrial and commercial uses. West of the site are some residential and commercial uses. The topography within and surrounding the site is essentially flat. ' The center of the City of Fort Collins is located west of the site. Roads r The primary streets which will serve the proposed project within the study area are: Timberline Road, SH 14 (Mulberry Street), and Prospect Road. Timberline Road is classified as a six lane arterial. Currently, it has a two lane cross section. At SH14, Timberline Road has four travel lanes, right -turn lanes, left -turn lanes, and bike facilities. At Prospect Road, Timberline Road has two travel lanes, right -turn lanes, left -turn lanes, and bike facilities. At Drake Road, Timberline Road has two travel lanes, left -turn lanes, no right -turn lanes, and limited bike facilities. The speed limit in the study area is 40 mph. SH14 is a state highway which provides access from Interstate 25 to the City of Fort Collins. At Timberline Road, SH14 has four travel lanes, right -turn lanes, left -turn lanes, and paved shoulders that function as bike facilities. The speed limit in the study area is 45 mph. Prospect Road is a four lane arterial. At Timberline Road, Prospect Road has four travel lanes and left -turn lanes. At .Riverside Avenue, Prospect Road has four travel lanes, left -turn lanes, and a westbound right -turn lane. There are no bike facilities along Prospect Road. The speed limit in the study area is 35 mph. Existing Motor Vehicle Traffic 1 Existing traffic flow data was collected in order to form a basis for the traffic study. Traffic counts were performed at the key intersections in November 1998. The volumes are shown in Figure 2. Count data is provided in Appendix A. Table 1 shows the current operation at the key \ intersections. Calculation forms are provided in Appendix B. Operation is acceptable at the key intersections, except at the Timberline/Drake intersection. At Timberline/Drake in the afternoon peak hour , the eastbound left turning and through vehicles operate at level of service F, the southbound right turning and through vehicles operate at level of service E, and the northbound left turning vehicles operate at level of 2 i F I. INTRODUCTION This transportation impact study addresses the capacity, geometric, and control requirements at and near the proposed Timber Lakes Business Park, located north of Prospect Road, along Timberline Road in Fort 1 Collins, Colorado. The transportation analysis will address potential vehicular impacts upon the roadway system. Traffic projections will be prepared for future Years 2001, 2009, and 2020. During the course of the analysis, numerous contacts were made with the project landscape architect/planner, project engineering consultant, and City of Fort Collins Traffic Operations Department. 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. This report is prepared for the following purposes: - Describe existing conditions; Estimate the trip generation by the proposed/assumed developments; Determine the trip distribution of site generated traffic; - Evaluate level of service for future Years 2001, 2009, and 2015; - Determine the geometrics at key intersections; - Determine the impacts of site generated traffic at key intersections. Information used in this report was obtained from the City of Fort Collins Traffic Operations Department, the planning and engineering consultants, the developers, research sources (ITE, TRB, etc.), and field reconnaissance. The following traffic studies were reviewed and considered in preparing this study: - Rigden Farms (proposal) - Operational Analysis --Timberline Extension and SH 14 - Timberline Industrial Park Spring Creek Center d i I i ,I n i t LIST OF FIGURES Figure 1.
