INTRODUCTION This intermediate transportation impact study (TIS) addresses the capacity, geometric, and control requirements at and near the proposed Overlook at JFK. The proposed Overlook at JFK is located south of Horsetooth Road and east of (adjacent to) JFK Parkway in Fort Collins, Colorado. During the course of the analysis, numerous contacts were made with the owner/developer, the project planner (Ripley Design, Inc.) and the Fort Collins Traffic Engineering staff. This study generally conforms to the format set forth in the Fort Collins transportation impact study guidelines contained in the “Larimer County Urban Area Street Standards” (LCUASS). Appendix A contains the Transportation Impact Study Base Assumptions form and related attachments for the Overlook at JFK. 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. DELICH Overlook at JFK TIS, February 2016 ASSOCIATES Page 2 II. EXISTING CONDITIONS The location of the Overlook at JFK 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 commercial and residential. There are residential uses to the east and southeast of the site. There are commercial uses to the north, south, and west of the site. The center of Fort Collins lies to the north of the proposed Overlook at JFK site. Land adjacent to the site is flat (<2% grade) from a traffic operations perspective. Roads The primary streets near the Overlook at JFK site are Horsetooth Road and JFK Parkway. The existing geometry at the key intersections is shown in Figure 2. Horsetooth Road is to the north of the proposed Overlook at JFK site. It is an east-west street classified as a four-lane arterial according to the Fort Collins Master Street Plan. Currently, Horsetooth Road has a four-lane cross section with a raised center median. At the Horsetooth/JFK Parkway intersection, Horsetooth Road has eastbound and westbound left-turn lanes and two through lanes in each direction. The Horsetooth/JFK Parkway intersection has signal control. The posted speed limit in this area of Horsetooth Road is 35 mph. JFK Parkway is to the west of (adjacent to) the proposed Overlook at JFK site. It is a north-south street classified as a four-lane arterial, south of Horsetooth Road, according to the Fort Collins Master Street plan. Currently, JFK Parkway has a four- lane cross section with a raised center median between the Horsetooth/JFK Parkway intersection and the JFK Parkway/US Bank-Office Access intersection. At the Horsetooth/JFK Parkway intersection, JFK Parkway has northbound and southbound left-turn lanes, one northbound through lane, two southbound through lanes, and a northbound right-turn lane. South of the JFK Parkway/US Bank-Office Access intersection, JFK Parkway has a center continuous two-way left-turn lane. The posted speed limit in this area of JFK Parkway is 35 mph. Existing Traffic Figure 3 shows recent peak hour traffic counts at the Horsetooth/JFK Parkway, JFK Parkway/US Bank-Office Access, and JFK Parkway/Great Western Bank Access intersections. The traffic counts at the Horsetooth/JFK Parkway intersection were obtained in February 2015 by the City of Fort Collins.

Raw traffic count data is provided in Appendix B. Since the counts were done on different days, the counts were adjusted/ balanced. The adjusted/balanced recent peak hour traffic is shown in Figure 4. Existing Operation The Horsetooth/JFK Parkway, JFK Parkway/US Bank-Office Access, and JFK Parkway/Great Western Bank Access intersections were evaluated using techniques provided in the 2010 Highway Capacity Manual. Calculation forms are provided in Appendix C. Using the morning and afternoon peak hour traffic shown in Figure 4, the peak hour operation is shown in Table 1. The current City signal timing was used for the Horsetooth/JFK Parkway intersection. A description of level of service for signalized and unsignalized intersections from the 2010 Highway Capacity Manual is provided in Appendix C. Table 4-3 (revised per staff comments regarding type of intersection) showing the Fort Collins Motor Vehicle LOS Standards (Intersections) are also provided in Appendix C. This site is in an area termed “Employment District” on the Fort Collins Structure Plan. The Horsetooth/JFK Parkway intersection is assumed to be in an area termed “Commercial Corridor.” This In areas termed “Commercial Corridor,” acceptable overall operation at signalized intersections during the peak hours is defined as level of service D or better. At signalized intersections, acceptable operation of any leg and any movement is level of service E. At arterial/arterial and arterial/collector or local stop sign controlled intersections, there is no acceptable level of service indicated. The key intersections will meet the City of Fort Collins Motor Vehicle LOS Standard during in the morning and afternoon peak hours. It is important to note that an eastbound right-turn at the Horsetooth/JFK Parkway intersection is warranted with the existing traffic volumes. Also, left-turn lanes are required on all arterial streets. Therefore, there should be a southbound left-turn lane at the JFK Parkway/US Bank-Office Access intersection. If the City chooses to implement this left-turn lane, a portion of the raised median would need to be removed/modified. Pedestrian Facilities There are sidewalks along both sides of Horsetooth Road and JFK Parkway, except for the frontage of the Overlook at JFK site. Bicycle Facilities Bicycle lanes exist along JFK Parkway within the study area. There are no bike lanes along Horsetooth Road. Transit Facilities Currently, this area of Fort Collins is served by Transfort routes 5, 6, and 12.

PROPOSED DEVELOPMENT The Overlook at JFK is a proposed residential and office development. Figure 5 shows a site plan of the Overlook at JFK. The Overlook at JFK is proposed as 87 apartment dwelling units and approximately 12,000 square feet of office use. Access to the Overlook at JFK will be via an existing full-movement access (US Bank Access) to/from JFK Parkway and a full-movement access to/from JFK Parkway that lines up with the Great Western Bank Access. The short range analysis (Year 2020) includes development of the Overlook at JFK site and an appropriate increase in background traffic, due to normal growth, and other approved or expected developments in the area. Trip Generation Trip generation is important in considering the impact of a development such as this upon the existing and proposed street system. A compilation of trip generation information contained in Trip Generation, 9 th Edition, ITE was used to estimate trips that would be generated by the Overlook at JFK project. For the residential portion of the site, Land Use Code 220 – Apartment was used and Land Use Code 710 - General Office was used for the office portion. Table 2 shows the daily and peak hour trip generation for Overlook at JFK project. Full development of the Overlook at JFK resulted in 782 daily weekday trip ends, 65 morning peak hour trip ends, and 84 afternoon peak hour trip ends.

Background traffic projections for the short range were obtained by reviewing the North Front Range Regional Transportation Plan, and engineering judgment. Based upon these sources, it was determined that the traffic volumes would increase by approximately 2.0 percent per year. 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. Using the trip distribution shown in Figure 6, Figure 8 shows the assignment of the site generated peak hour vehicle traffic. The site generated vehicle traffic was combined with the background traffic to determine the total forecasted vehicle traffic at the key intersections. Figure 9 shows the short range (2020) total peak hour vehicle traffic at the key intersections. 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 JFK Parkway/US Bank-Office Access and JFK Parkway/Great Western Bank-Site Access intersections will not meet peak hour signal warrants, nor do the two intersections meet signal spacing criteria. Geometry Figure 10 shows a schematic of the short range (2020) geometry. As mentioned earlier, an eastbound right-turn at the Horsetooth/JFK Parkway intersection is warranted with the existing traffic volumes. In addition, a southbound left-turn lane is required approaching the JFK Parkway/US Bank-Office Access intersection. Implementation of either/both of these auxiliary lanes would require changes to existing curb/gutter and landscaping. In the case of the eastbound right-turn lane on Horsetooth Road, it would require moving a signal pole. The need for these changes rests with the City. It is recommended that the center continuous two-way left-turn lane remain on JFK Parkway. No other auxiliary lanes are required. Operation Analysis Operation analyses were performed at the Horsetooth/JFK Parkway, JFK Parkway/US Bank-Office Access, and JFK Parkway/Great Western Bank-Site Access intersections. The operation analyses were conducted for the short range analysis, AM/PM SHORT RANGE (2020) BACKGROUND PEAK HOUR TRAFFIC Figure 7 DELICH ASSOCIATES Overlook at JFK TIS, February 2016 Page 13 40/122 23/51 112/330 21/64 11/64 18/56 83/97 961/895 68/110 28/39 893/954 185/317 30/6 167/460 9/8 42/8 219/475 3/8 6/30 1/0 2/38 2/13 2/1 5/21 10/2 205/464 14/2 212/532 1/10 1/13 Horsetooth Office Access US Bank Access Great Western Bank Access JFK Parkway AM/PM SITE GENERATED PEAK HOUR TRAFFIC Figure 8 DELICH ASSOCIATES Overlook at JFK TIS, February 2016 Page 14 13/12 2/2 7/8 1/2 8/15 5/9 Horsetooth Office Access US Bank Access Great Western Bank Access JFK Parkway 10/22 4/4 18/17 3/3 4/5 3/3 Site Access 3/3 10/22 3/3 9/17 18/17 14/13 AM/PM SHORT RANGE (2020) TOTAL PEAK HOUR TRAFFIC Figure 9 DELICH ASSOCIATES Overlook at JFK TIS, February 2016 Page 15 53/134 25/53 119/338 21/64 12/66 18/56 83/97 961/895 76/125 28/39 893/954 190/326 30/6 185/477 12/11 42/8 229/497 7/12 6/30 1/0 2/38 6/18 2/1 8/24 Horsetooth Office Access US Bank Access Great Western Bank Access JFK Parkway Site Access 10/2 208/467 9/17 14/2 215/535 10/22 1/10 NOM 1/13 18/17 NOM 14/13 SHORT RANGE (2020) GEOMETRY Figure 10 DELICH ASSOCIATES Overlook at JFK TIS, February 2016 Page 16 Horsetooth Office Access US Bank Access Great Western Bank Access JFK Parkway - Denotes Lane _ Two-way Continuous Left-turn Lane Site Access Warranted - Warranted - DELICH Overlook at JFK TIS, February 2016 ASSOCIATES Page 17 reflecting a year 2020 condition. The current City signal timing was used for the Horsetooth/JFK Parkway intersection. The following analyses do not reflect the warranted auxiliary lanes. Using the short range (2020) background peak hour traffic volumes, the Horsetooth/JFK Parkway, JFK Parkway/US Bank-Office Access, and JFK Parkway/Great Western Bank Access intersections operate as indicated in Table 3. The key intersections operate acceptably with existing control, geometry, and signal timing in the morning and afternoon peak hours. Calculation forms for these analyses are provided in Appendix D. Using the traffic volumes shown in Figure 9, the Horsetooth/JFK Parkway, JFK Parkway/US Bank-Office Access, and JFK Parkway/Great Western Bank-Site Access intersections operate in the short range (2020) total condition as indicated in Table 4. Calculation forms for these analyses are provided in Appendix E. The key intersections operate similar to the background operation with existing control and signal timing in the morning and afternoon peak hours. The Horsetooth/JFK Parkway and JFK Parkway/US Bank-Office Access intersections operate acceptably without the warranted auxiliary lanes. Pedestrian Level of Service Appendix F shows a map of the area that is within 1320 feet of the Overlook at JFK development. There are five pedestrian destinations within 1320 feet of the Overlook at JFK development. These are: 1) the commercial area to the north of the site; 2) the commercial area to the west of the site; 3) the commercial uses along College Avenue; 4) the commercial uses to the south of the site; and 5) the residential neighborhood to the east of the site. The Overlook at JFK site is located within an area termed as “activity center,” which sets the level of service threshold at LOS B for all measured categories, except for street crossing which is LOS C. Pedestrian level of service is achieved. The Pedestrian LOS Worksheet is provided in Appendix F. Bicycle Level of Service Appendix F shows a map of the area that is within 1320 feet of the Overlook at JFK development. There are four bicycle destinations within 1320 feet of the Overlook at JFK development. These are: 1) the commercial area to the north of the site; 2) the commercial area to the west of the site; 3) the commercial uses along College Avenue; and 4) the commercial uses to the south of the site. The Bicycle LOS Worksheet is provided in Appendix F. The minimum level of service for this site is C. This site is connected to bike lanes on JFK Parkway. Therefore, it is concluded that level of service C can be achieved. Transit Level of Service This area of Fort Collins is served by Transfort Routes 5, 6, and 12.

CONCLUSIONS/RECOMMENDATIONS This study assessed the impacts of the Overlook at JFK development on the short range (2020) street system in the vicinity of the proposed development. As a result of this analysis, the following is concluded: • The development of the Overlook at JFK site is feasible from a traffic engineering standpoint. At full development, the Overlook at JFK site will generate approximately 782 daily weekday trip ends, 65 morning peak hour trip ends, and 84 afternoon peak hour trip ends. • Current operation at the Horsetooth/JFK Parkway, JFK Parkway/US Bank-Office Access, and JFK Parkway/Great Western Bank Access intersections is acceptable with existing control, geometry, and signal timing. • Figure 10 shows a schematic of the short range (2020) geometry. It is important to note that an eastbound right-turn at the Horsetooth/JFK Parkway intersection is warranted with the existing traffic volumes and the southbound left-turn lane at the JFK Parkway/US Bank-Office Access intersection. Implementation of these auxiliary lanes rests with the City of Fort Collins. • In the short range (2020) future, given development of the Overlook at JFK and an increase in background traffic, the Horsetooth/JFK Parkway, JFK Parkway/US Bank-Office Access, and JFK Parkway/Great Western Bank-Site Access intersections will meet the City of Fort Collins Motor Vehicle LOS Standard, without the warranted auxiliary lanes. • Acceptable level of service is achieved for pedestrian, bicycle, and transit modes based upon the measures in the multi-modal transportation guidelines.
