INTRODUCTION ' This intermediate transportation impact study (TIS) addresses the capacity, geometric, and control requirements at and near a proposed Walgreen's Drug Store. The proposed Walgreen's Drug Store is located north of Harmony Road and east of Timberline Road in the Harmony School Shops site in Fort Collins, Colorado. During the course of the analysis, numerous contacts were made i� with the project owner/developer (Hunt Douglas Real Estate Service, Inc.) and the City of Fort Collins staff. This study conforms to the format set forth in the Fort Collins transportation impact study ' guidelines as contained in the "Larimer County Urban Area Street Standards" (LCUASS). A Base Assumptions Form and related information are provided in Appendix A. 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. 1 II. EXISTING CONDITIONS The location of the Walgreen's Drug Store 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 residential or commercial/office. There are residential uses to the north and east of the site. There are commercial uses south and west of the site. The center of Fort Collins lies to the northwest of the proposed Walgreen's Drug Store. Land adjacent to the site is flat (<2% grade) from a traffic operations perspective. The Walgreen's Drug Store is in an area termed "commercial corridor." Roads The primary streets near the Walgreen's Drug Store site are Harmony Road, Timberline Road, Snow Mesa Drive, and Milestone Drive. Figure 2 shows a schematic of the current geometry at the key intersections in the area. ' Harmony Road is adjacent to the south side of the Walgreen's Drug Store. It is an east -west street designated as a six -lane arterial street on the Fort Collins Master Street Plan. Currently, it has a four -lane cross section with appropriate auxiliary lanes. The existing speed limit in this area is 50 mph. Timberline Road is classified as a six -lane arterial on the Fort ' Collins Master Street Plan. Currently, Timberline Road has a four -lane cross section with auxiliary lanes at Harmony Road. The Harmony/Timberline intersection has signal control. The existing speed ' limit in this area is 40 mph. Snow Mesa Drive is a north -south street designated as a collector street south of Harmony Road on the Fort Collins Master Street Plan. Currently, Snow Mesa Drive has a two-lane cross section south of Harmony Road. North of Harmony Road, Snow Mesa Drive serves a mobile home park. ' The Harmony/Snow Mesa intersection has signal control. The existing speed limit is 25 mph south of Harmony Road, and 15 mph north of Harmony Road. Milestone Drive is an east -west street designated as a local street on the Fort Collins Master Street Plan. Currently, Milestone Drive has a two-lane section. The Timberline/Milestone intersect has ' stop sign control on Milestone Drive. There is no posted speed limit on Milestone Drive.

The traffic data for the Harmony/Timberline intersection was collected in January 2006. The traffic data for the ' Harmony/Snow Mesa intersection was collected in September 2005. The traffic data for the Timberline/Milestone intersection was collected in May 2006. Raw traffic counts are provided in Appendix A. Existing Operation ' The key intersections were evaluated using techniques provided in the 2000 Highway Capacity Manual. Using the peak hour traffic shown in Figure 3, the peak hour operation is shown in Table 1. Calculation ' forms are provided in Appendix B. The key intersections operate acceptably during both the morning and afternoon peak hours, except for the Harmony/Timberline intersection during the afternoon peak hour and the Timberline/Milestone intersection during both the morning and afternoon peak hours. The Walgreen's Drug Store site is in an area termed "commercial corridor." In "commercial corridors," 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 unsignalized intersections, in commercial corridors, there is no ' minimum level of service criteria. In other TIS', Fort Collins staff has indicated the level of service E is considered to be acceptable. A description of level of service for signalized and unsignalized ' intersections from the 2000 Highway Capacity Manual and a table showing the Fort Collins Motor Vehicle LOS Standards (intersections) are also provided in Appendix B. Pedestrian Facilities Pedestrian facilities in this area are sporadic. Sidewalks exist adjacent to developed properties. Sidewalks will be incorporated within and adjacent to this development. Bicycle Facilities Bicycle lanes exist on Harmony Road and Timberline Road. Bike lanes are not required on local or connector streets. Transit Facilities Currently, Transfort does not serve this area of Fort Collins. 5 n t�p N 25/21 37/50 0 v cv 0 m c m .fl E H 00 O) N 425/336 � CD cn c9 " -F— 1089/1338 J 98/250 /— 276/316 1038/1051 —► 172/376 r- v N LO w a 0 00 Ln n .- ilestone Drive Harmony Road --•-- AM/PM RECENT PEAK HOUR TRAFFIC 6 I& N N Cl � � 16/34 N 00N — 1470/1621 J 1— 27/8 38/102 --)1 t r 1414/1451 - — 00 N v 81 /38 � Lo o ,� Figure 3 TABLE 1 Current Peak Hour Operation Intersection Movement Level of Service AM PM Harmony/Snow Mesa (signal) EB LT B D EB T A A EB RT A A EB APPROACH A A WB LT A A WB T/RT A B WB APPROACH A B NB LT D D NB T/RT D D NB APPROACH D D SB LT D D SB T D D SB RT D D SB APPROACH D D OVERALL B B Harmony/Timberline (signal) EB LT E F EB T C C EB RT A B EB APPROACH C D WB LT D E WB T D E WB RT C E WB APPROACH D E NB LT E F NB T D D NB RT C E NB APPROACH D E SB LT E E SB T D E SB RT D D SB APPROACH D D OVERALL D E Timberline/Milestone (stop sign) WB LT E F WB RT B B WB APPROACH D E SB LT B B III. PROPOSED DEVELOPMENT The Walgreen's Drug Store is located north of Harmony Road and east of Timberline Road in the Harmony School Shops. Figure 4 shows a site plan of the Walgreen's Drug Store. The site plan provided by the planning consultant shows the general layout of the site. The opening of the right-in/right-out/left-in access along Harmony Road is proposed with this site. The Walgreen's Drug Store will also gain access to/from the site via Snow Mesa, Milestone Drive, and the existing right-in/right-out on Timberline Road. The short range analysis (year 2009) includes development of only the Walgreen's Drug Store and an appropriate increase in background traffic due to normal growth,and other known potential developments in the area. Since this is an intermediate level transportation impact study, a long range analysis is not required. When the remainder of the Harmony School Shops retail center develops, another transportation impact study will be prepared. Trip Generation Trip generation is important in considering the impact of a development such as this upon the existing and proposed street system. Trip generation information contained in Trip Generation, 7th Edition, ITE, was used to estimate trips that would be generated by the Walgreen's Drug Store. Table 2 shows the expected trip generation on a daily and peak hour basis. Due to the retail related land use on the proposed site, a percentage of the traffic will be "pass -by" traffic. This is traffic that will be using the existing street network. The pass -by traffic was determined using the guidelines in Chapter 5 of the Trip Generation Handbook, ITE.

Figure 5 shows the short range (2009) trip distribution used for the peak hour traffic assignment. The trip distribution analysis was discussed in the scoping meeting. 8 fl ' BVB,orlro9 fl fl RETAIL S.F.

Background traffic projections for the future horizon year were obtained by reviewing the NFRRTP, reviewing traffic studies for other developments, and reviewing historic count data for this area of Fort Collins. The Front Range Village traffic was included in ' the background traffic forecasts, even though this development has not been formally submitted to the City. This was agreed to in the scoping discussions. It is acknowledged that the Front Range Village ' will have a much greater impact on the key intersections compared to the proposed Walgreen's Drug Store. This is especially significant at the Harmony/Timberline intersection. Trip Assignment/Total Traffic Projections 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. Figure 7 shows the short range (2009) site generated peak hour traffic assignment of the Walgreen's Drug Store. As mentioned earlier, with development of the Walgreen's Drug Store site, an internal connection will be made to the north leg of Snow Mesa Drive. This connection has the potential to eliminate the delay associated with the westbound left turns at the Timberline/Milestone intersection and the delays associated with the southbound left turns at the Harmony/Timberline intersection for the background traffic that is westbound on Milestone Drive that desires to go east on Harmony Road. It is expected that these drivers will find this connection and utilize it. The short range total traffic reflects that 15 vehicles would do this in each peak hour. Figure 8 shows the short range (2009) total (site plus background) peak hour traffic at the key intersections with the development of the Walgreen's Drug Store. Signal Warrants Signal Warrants were not analyzed in this TIS. The Harmony/Snow ' Mesa and Harmony/Timberline intersections are signalized. The Milestone and site access intersections do not meet signal spacing requirements, and will not be signalized. Geometry Figure 9 shows a schematic of the short range (2009) geometry. In a previous TIS (Front Range Village, May 2006), it was shown that the operation at the Harmony/Timberline intersection will be unacceptable with two through lanes in each direction of Harmony. Therefore, Harmony Road was analyzed with three through lanes in each direction. Without the Front Range Village traffic, the Harmony/Timberline intersection can have the existing geometry. The Timberline/Milestone intersection was assumed to be a channelized T-intersection. 11 LO N O � C �- '- Cl) 35/40 1 � � 45/65 10 o M 0 M LO cM 15/10 U- N o N V N ra 0 0 LO465/525 LO " � v►— 1140/1420 120/355 275/290 1175/1255 2301375 Cl) Cl`r-' o (14 0 N n N ilestone Drive AM/PM Rounded to Nearest 5 Vehicles Right-in/Right-out Harmony Road SHORT RANGE (2009) BACKGROUND PEAK HOUR TRAFFIC I& N Co o N — 15/35 zz " —1570/2080 75/55 40/105 `1 T 1600/1720 o g o 100/40 4 O n z C, m Figure 6 12 o 1 /3 Milestone Drive N 5/18 Right-in/Right-out � M _c O E r N0).c: \ 4 J L R i O �— 2/7 O1 N ^ 3/13 4/13 �— -21-9 1/2 ( 4/17 2/4 —► c� CM N .- -1/-7 — SHORT RANGE (2009) SITE GENERATED PEAK HOUR TRAFFIC 13 4h� T AM/PM N +— 2/4 -va — Harmony Road Figure 7 A& CD CV N O � `r 35/45 30/50 Milestone Drive Ln o a� Cl)o • AM/PM Rounded to Nearest 5 Vehicles 20/30 Right-in/Right-out cc o > N of � L C C N cu Qi 0 = cc i— N J O a U) L IE rn o Ln 8_ 01 M p ` `— c ) `r `r 465/525 — 1145/1430 a o w Z 2 15/35 „-1575/2085 J j 125/370 1 T 5/15 �— 17251 95 5/20 —� Harmony Road + 40/105 /—75/55 280/295 1180/1260 o Ln an 1725/1840 —► 1585/1695 _ o 0 230l375 —141 � m _- 100/40 O tn Z N Cl) Ln r- N N SHORT RANGE (2009) TOTAL PEAK HOUR TRAFFIC Figure 8 14 111"r Drive Right-in/Right-out STOP Harmony Road - Denotes Lane a� 0 ca 0 m 0 ''c^ V/ 1� � SHORT RANGE (2009) GEOMETRY Figure 9 15 Operation Analysis Operation analyses were performed at the key intersections. The operations analyses were conducted for the short range analysis, reflecting a year 2009 condition. In the Front Range Village TIS, City staff recommended that a peak hour factor of 0.92 be used in the short range future for Harmony Road and Timberline Road. This was also done for the short range in this study. The peak hour factor of 0.92 is the recommended default in the Highway Capacity Manual (HCM). Using the traffic volumes shown in Figure 6, the key intersections operate in the short range (2009) background traffic condition as indicated in Table 3. Calculation forms for these analyses are provided in Appendix C. The key intersections will operate acceptably during the morning and afternoon peak hours with three lanes in each direction on Harmony Road. At the Timberline/Milestone intersection, the minor street left turns will operate at level of service F with the current intersection geometry. This intersection was analyzed as a channelized T-intersection, since that was the recommended solution in a previous TIS. As a channelized T-intersection, this intersection will operate acceptably, except at the Timberline/Milestone intersection in the afternoon peak hour. Both analyses are provided in Appendix C. Using the traffic volumes shown in Figure 8, the key intersections operate in the short range (2009) total traffic condition as indicated in Table 4. Calculation forms for these analyses are provided in Appendix D. All the key intersections, with the warranted improvements, will operate acceptably. As with the short range background traffic, minor street left -turns at the Timberline/Milestone intersection will operate at level of service F with the current intersection configuration. Acceptable operation is achieved as a channelized T- intersection. Both analyses are provided in Appendix D. It is important to note that it is not likely that the Walgreen's Drug Store would add traffic to the westbound left -turn movement at this intersection. There are other routes available that involve either right turns or already signalized intersections. Therefore, the implementation of the channelized T-intersection should be the responsibility of the Harmony School Shops development as a whole and the City of Fort Collins. In these analyses, it was assumed that the Walgreen's Drug Store would provide a connection to the recently installed Harmony/Snow Mesa signalized intersection. This connection is key to achieving acceptable operation in this area. It was assumed that some left -turning traffic from Milestone Drive bound for eastbound Harmony Road would use the connection to the north leg of Snow Mesa Drive to circumvent the left -turn at a stop sign controlled intersection. This is shown in the short range (2009) total peak hour traffic. 16 TABLE 3 Short Range (2009) Background Peak Hour Operation Intersection Movement Level of Service AM PM Harmony/Snow Mesa (signal) EB LT A D EB T A A EB RT A A EB APPROACH A A WB LT B A WB T/RT B A WB APPROACH B A NB LT D D NB T/RT D D NB APPROACH D D _ SB LT D D SB T D D SB RT D D SB APPROACH D D OVERALL B A Harmony/Timberline (signal) EB LT E E EBT _ C D EB RT A E EB APPROACH C D WB LT D _ D WB T C C WB RT D C WB APPROACH D DNB LT D E - NB T D D NB RT D D NB APPROACH D E SB LT D D SB T D D SB RT D D SB APPROACH D D OVERALL D D Timberline/Right-in/Right-out (stop sign) WB RT B B Timberline/Milestone (stop sign)(channelized T) WB LT E F WB RT C B WB APPROACH D E SB LT B C 17 TABLE 4 Short Range (2009) Total Peak Hour Operation Intersection Movement Level of Service AM PM Harmony/Snow Mesa (signal) EB LT A D EB T A A EB RT A A EB APPROACH A A WB LT B A WB T/RT B A WB APPROACH B _ A NB LT D D NB T/RT D D NB APPROACH D D SB LT D D SB T D D SB RT D E SB APPROACH D D OVERALL B A Harmony/Right-in/Right-out/Left-in (stop sign) EB LT C D SB RT B B Harmony/Timberline (signal) EB LT E E EB T C D EB RT A E EB APPROACH C D WB LT D D WB T C D WB RT D C WB APPROACH D D NB LT D E NB T D D NB RT D D NB APPROACH D E SB LT D D SB T D D SB RT D D SB APPROACH D D OVERALL D D Timberline/Right-in/Right-out (stop sign) WB RT B B Timberline/Milestone (stop sign)(channelized T) WB LT E E WB RT _ C B WB APPROACH D _ D SB LT C C 18 Drive -Through Lanes These are double drive -through lanes on the east side of the Walgreen's Drug Store. Fort Collins staff comments requested that this be addressed in the TIS. Typically, a TIS addresses the site access and off -site impacts of a given site. The drive -through aspect of a development is only addressed in a TIS if there is a chance that the drive -through queue will be significant enough to negatively impact a public street. The storage length of the drive -through lanes (2) is 280 feet in each lane. This is enough length to store 12 vehicles in each lane. Based upon conversations with the owner/developer, it is not likely that there would ever be a storage requirement for that many vehicles in either of the drive -through lanes. Therefore, it is concluded that the drive -through lanes will not negatively impact the on -site circulation driveways or any of the public street intersections. The owner/developer was contacted with regard to the need for two drive -through lanes. The outer drive -through lane (not adjacent to the building) is only used to drop-off prescriptions through a pneumatic tube. This lane would move very quickly, since no money changes hands. It allows the drop-offs to not wait in the same lane with the pick-ups, which will take longer. It is not likely that there would be more than 3 vehicles in this lane. Having two drive -through lanes will reduce delay overall. Pedestrian Level of Service ' Appendix E contains a map of the pedestrian influence area that is within 1320 feet of the Walgreen's Drug Store. There will be four pedestrian destinations within 1320 feet of the Walgreen's Drug Store. These are: 1) the mobile home park east of the site, 2) the residential area (Sunstone) to ' the north of the site, 3) the residential area to the west of the site, and 4) the PVH Harmony campus medical center and commercial area to the south of the site. This site is in an area type termed "activity corridor." The minimum level of service for "activity corridor" is B for all categories. ' Acceptable pedestrian level of service cannot be achieved for all pedestrian factors. The Pedestrian LOS Worksheet is provided in Appendix E. Bicycle Level of Service Based upon Fort Collins bicycle LOS criteria, there is one bicycle destination within 1320 feet of the Walgreen's Drug Store. It is the commercial area in the southwest quadrant of the Harmony/Timberline intersection. This site will achieve bicycle level I of service B connectivity which exceeds the base city-wide minimum. 11 11 Transit Level of Service ' Currently, this area has no transit service. The Fort Collins Transit System Map shows that Harmony Road will be an enhanced travel corridor (10 minute service) in the long range future. Transit level of service will be acceptable in the long range future. However, transit service is not expected to be implemented in this area in the short range future that was analyzed in this TIS. 11 11 11 U, 11 IV. CONCLUSIONS This study assessed the impacts of the Walgreen's Drug Store on the short range (2009) street system in the vicinity of the proposed development. As a result of this analysis, the following is concluded: - The development of the Walgreen's Drug Store is feasible from a traffic engineering standpoint. At full development, the Walgreen's Drug Store will generate approximately 1280 daily trip ends, 39 morning peak hour trip ends, and 125 afternoon peak hour trip ends. - Current operation at the key intersections is acceptable, except at the Timberline/Milestone intersection_ In the short range (2009) future, given development of the Walgreen's Drug Store and an increase in background traffic, the key intersections are shown to operate acceptably, overall. The Harmony/Timberline intersection will require three through lanes in each direction on Harmony to achieve acceptable operation. This three through lane cross section was needed due to the Front Range Village traffic. Without the Front Range Village traffic, this intersection will operate acceptably with the current geometry. The Timberline/Milestone intersection will operate acceptably with the channelized T-intersection. The channelized T-intersection is not required due to the Walgreen's Drug Store. - Bicycle and transit level of service will be acceptable. Acceptable level of service for all pedestrian factors cannot be achieved. 21
