CONCLUSIONS ' This study assessed the transportation needs associated with increasing background traffic volumes and the development of the Poudre Valley Plaza. Identified improvements are stated below for both short and long range futures. Short Range Improvements 1. A westbound right -turn lane on Horsetooth Road at Shields Street. 2. A southbound left -turn lane on Shields Street at Arbor Avenue. 3. A taper and radius for right -turning traffic from eastbound Horsetooth Road to Century Drive. 4. A right -turn deceleration lane on Horsetooth Road at the site access drive. 5. Two lane approach on Arbor Avenue approaching Shields Street. 6. A taper and radius on Shields Street approaching Arbor Avenue. Long Range Improvements 1. Widen Shields Street to four lane roadways with a center left - turn lane. 2. An additional southbound left -turn lane on the Shields Street approach to Horsetooth Road. 3. A northbound right -turn lane on Shields Street at Arbor Avenue. With the above noted improvements, acceptable traffic operations can be maintained in the immediate area of the Poudre Valley Plaza. These improvements can be expected to mitigate traffic associated with the Poudre Valley Plaza and the general growth in traffic volumes. C VI. DISCUSSION/DESIGN CONSIDERATIONS Each identified improvement was reviewed for the purpose of defining storage length requirements, taper lengths, etc. This resulted in the findings stated below. When widened roadway sections are needed, the widening is assumed to extend through and beyond the study area and, therefore, further definition of these improvements was not necessary. - The right -turn lane on the westbound Horsetooth Road approaching Shields Street should be 300 feet long. - The southbound left -turn lane on Shields Street at Arbor Avenue should have 50-75 feet of storage. Given the 500 foot spacing between Horsetooth Road and Arbor Avenue, a stacking distance problem is not anticipated. - The right -turn taper on eastbound Horsetooth Road at Century Drive should be approximately 100 feet. Additionally, a large radius (20-30 feet) should be provided at the end of the taper. - A full width right -turn lane on eastbound Horsetooth Road at the right-in/right-out site access should be constructed to allow safe deceleration and an efficient right turn into the site. A second southbound left -turn lane on the Shields Street approach to Horsetooth Road is needed in the long range future. The two combined lanes should provide 400-500 feet of vehicle storage. - The northbound right -turn lane on Shields Street at Arbor Avenue should be 310 feet including taper. The above storage requirements are based upon long range future traffic volumes which may or may not materialize. Accordingly, monitoring the street system in the vicinity of the Poudre Valley Plaza is appropriate. For example, if an expanded roadway system is implemented, a major shift in turning movement traffic volumes may occur. If so, the need for a southbound double left -turn lane on Shields Street at Horsetooth Road may be eliminated. 7 - Widening of Shields Street to a five lane cross section, with two through lanes in each direction and a center left -turn lane; Adding an additional southbound left -turn lane at the Horsetooth/Shields intersection; Providing a northbound right -turn lane on Shields Street at Arbor Avenue. Some of the improvements recommended in both the short range and long range futures are due to background traffic. System wide improvements elswhere, may mitigate some of the above recommendations. Periodic evaluation should be conducted by the City or through traffic studies for other developments. N.

TRANSPORTATION IMPACTS The key intersections were analyzed using the unsignalized and signalized analysis techniques as published in the most recent "Highway Capacity Manual." Table 3 shows the level of service at the key intersections in the short range future. Calculation forms are provided in Appendix C. The analyzed intersections operate acceptably, except for minor street left turns at the Horsetooth/Century and Arbor/ Shields intersections in the afternoon peak hour. Occasional level of service E and F operation for minor street left turns is normal during some peak hours on busy streets in Fort Collins. Signals are not warranted at the Arbor/Shields. intersection based upon the projected peak hour traffic. At the Horsetooth/Century intersection, traffic signals are marginally warranted based upon, forecasted afternoon peak hour traffic volumes. Traffic signal installation is not assumed given uncertainties associated with traffic volume projections. In order to obtain the levels of service indicated on Table 3, traffic volumes and applicable warrants were evaluated. This resulted in the determination that the following improvements are needed in the short range future: - A right -turn lane on the westbound Horsetooth Road approach to Shields Street; - Construction of a southbound left -turn lane on Shields Street at the Arbor Avenue intersection; - A taper and increased radius on eastbound Horsetooth Road approaching Century Drive for right -turning vehicles; - A right -turn deceleration lane at the site access on Horsetooth Road; - Two outbound (from the site) lanes on the Arbor Avenue approaches to Shields Street; - A northbound taper and radius on Shields Street approaching Arbor Avenue. Table 4 shows operating levels of service at the key intersections in the long range future. As shown, critical left - turn movements continue to operate at less than desirable levels at the Horsetooth/Century and Shields/Arbor intersections. A calculation assuming traffic signal installation at the Horsetooth/ Century intersection indicated that LOS B can be obtained during both peak hours. At the Shields/Arbor intersection, traffic signals do not appear to be warranted and, therefore, signalization was not given further consideration. To obtain the levels of service indicated on Table 4, the .following improvements were deemed appropriate: 5 0 o00 O M �- 85/450 - o\ � OO2 /4040 HORSETOOTH 0/100 r NOM. 1040 f r 10/600 — I 75/75 u7 0 0 I n NOM./160 �� LO 0 z N � W Site co 1111 20 60 %I NOM./NOM.

N EXISTING PEAK HOUR TRAFFIC Figure 4 IV. TRAFFIC VOLUMES AND TRIP ASSIGNMENT 1. Morning and afternoon peak hour traffic counts were obtained at the key intersections. Raw count data is provided in Appendix A. The traffic data is shown in Figure 4. Balancing adjustments were made at the Horsetooth/Century intersection. This was done since the date of the count was after CR17 was closed to the south of Fort Collins. The Horsetooth/Shields intersection is signalized. Table 2 shows the level of service (LOS) analysis using the morning and afternoon peak hour traffic shown in Figure 4. Calculation forms are provided in Appendix B. All of the key Intersections operate acceptably. It should be noted that northbound and southbound left turn/through movements currently operate at LOS E at the Horsetooth/Century intersection in the afternoon peak hour. This is considered normal for critical movements at urban intersections under stop sign control. Traffic volume adjustments were made to through volumes on Horsetooth Road. ' These volumes were factored by 0.60 to account for uneven distribution in the two travel lanes. These adjustments result in more realistic operating levels of service as documented by field measurements. Trip Assignment iThe trip assignment is the product of the trip generation and trip distribution process. Both short range and long range trip assignments were performed. Since the Poudre Valley Plaza is assumed to be fully developed in the short term and the directional distribution is expected to remain constant, site traffic volumes for both the short and long range futures are identical. Figures 5 and 6 show the short range (year 1998) peak hour traffic. The site generated traffic was combined with the background traffic to determine the total traffic at the key intersections. Background traffic is defined as the traffic that is or will be on the area street system, but is not related to this specific development. The background traffic includes general increases of traffic on Horsetooth Road and traffic obtained from other traffic studies for proposed developments in this area. These specific studies include Stockbridge/Mountainridge Farms and Rose Tree Village. The volumes reflect the access shown on the site plan (Figure 2). Short range traffic volumes included development of about 100 single family residences to the east of the site. Figures 7 and a show long range (year 2015) peak hour traffic. In addition to the residential development east of the site for the short range future, an office complex having 70,000-75,000 square feet is assumed south of Arbor Avenue between Shields Street and Century Drive. 4 I 5%-10% w o� F- CC Mu 2 N HORSETOOTH ROAD A& N NO SCALE 45%-50% TRIP DISTRIBUTION Figure 3 III. TRIP DISTRIBUTION The overall directional distribution of the site generated traffic was based upon the existing travel patterns at the area intersections and in consideration of trip attractions and productions in this area of Fort Collins. Site specific access was determined on the basis of the shortest travel path to each building within the Poudre Valley Plaza. Figure 3 shows the trip distribution used in subsequent traffic assignments. 3 II. TRIP GENERATION Trip generation was estimated using Trip Generation, 5th Edition, ITE. Table 1 shows the daily and peak hour trip generation for this development. A trip is defined as a one way vehicle movement from origin to destination. The origin or destination of a generated trip would be within the site area. Poudre Valley Plaza is expected to generate 229 morning peak hour trips, 397 afternoon peak hour trips, and 3628 daily trips. It should be noted that reductions for captured and internal trips are not reflected in the number of trips stated above. Accordingly, a conservative approach was taken.

INTRODUCTION I This traffic study for the Poudre Valley Plaza addresses the capacity, geometric, and traffic control requirements associated with a proposed mixed use development south of Horsetooth Road, located between Shields Street and Century Drive in Fort Collins, Colorado. The site location is shown in Figure 1. Existing and Proposed Site Uses The land for this development is currently vacant. The applicant is proposing to construct seven buildings. It is expected that there will be a blend of office, retail, service and residential land uses. More specifically, 32,200 square feet of retail space, 28,100 square feet of office space, a 3500 square foot bank, a 6500 square foot restaurant and 7 townhomes are planned. The land in the area is flat. Figure 2 shows a site plan of the proposed Poudre Valley Plaza. :Site Access Access is proposed from Horsetooth Road, Century Drive, and Arbor Avenue. Arbor Avenue is a new east -west connector roadway between Shields Street and Century Drive. Both the Century Drive and Arbor Avenue accesses are intended to allow full turning movements. The Horsetooth Road access is currently planned as a right-in/right-out driveway. Existing Land Uses Land uses in the vicinity of the subject property are primarily small scale commercial and residential. There is commercial development along the northside of Horsetooth at both the Century Drive and Shields Street intersections. These developments are typically convenience stores, gas stations, and other small tenant retail users. Other areas surrounding the site are either residential developments or undeveloped land. 1 POUDRE VALLEY PLAZA SITE ACCESS STUDY FORT COLLINS, COLORADO JUNE 1995 Prepared for: Shields Street Investors, LLC P.O.
