The site is located approximately 2500 feet south of Harmony Road on M the west side of Shields Street. Along with the Veterinary Clinic, it was assumed that 9 dwelling units would be located to the west of the veterinary clinic. Access to both the vet clinic and the 9 dwelling units wa.s assumed to be via a private road intersecting with Shields Street at a T intersection. The traffic counts used as a base for the following analyses were taken from a memorandum on Clarendon Hills, Parcels H and I, dated September 2, 1987. The short range traffic projection utilized this data factored by 3 percent per year. The long range (2010) traffic projections utilized the 2006 peak hour traffic, z factored by 3 percent per year, taken from "The klard Smith Farm Site Access Stud;•," April 1986. W W CZ The trip generation from the proposed uses is shown Ui W in Table 1. The reference for the residential use trip generation is Trip Generation, 4th Edition, ITE. The a. vet clinic trip generation was estimated by Dr. Wi 1 1 i am • Plussl ewah i to , based upon his experience at other vet o clinics. The trip distribution used for the following J a traffic assignments were 90 percent to the north and 10 w iz percent to the south in the short range future and 75 c a percent to the north and 25 percent to the south in the Z long range future. Q • Figure 1 shows the results of the trip assignment 3 U_ at the access intersection in the short range future = a (15?0). The operation of this intersection is shown in Table 2. Calculation sheets__ are provided in Appendix A. age This intersection will operate acceptably (level of M service D or better) during the peak hours. At the location of the Vet Clinic Road, Shields Street is approximately 36 feet wide. The street is widened on the east side k.,ai th curb and gutter. This improvement was. made by the Clarendon Hills development. The v, e s.t side of Shields has a rural (shoulders) cross. section. Approximately 400 feet south of the Vet Clinic Road, Shields. Street returns to a two 1 a.ne rural cross. section. Ar_cordinq to the planning consultant for Clarendon Hills (Cityscape Urban Design), Shields Street will be widened to the same 36 foot cross section to at least the next intersecting street to the south during the summer of 19970. This will provide a 36 foot wide street at least 1500 feet south of the site. Since this 36 foot wide street is a. temporary condition unt i 1 the full arterial width (5 lanes) can be completed on the viest side of Shields, the 36 foot cross section should be striped as one northbound lane, one southbound lane, and a center lane which can be used as a. halo-t,,tay left - turn lane. This. should remove left -turn i no vehicles to this site (and other residences. on the west side of Shields.) from the through traffic lanes. The need for a southbound right -turn deceleration lane is judamenta.l. According to nomographs in the State Highway Access Code, a right -turn deceleration lane is needed. According to the "Intersection Channelization Design Guide," NCHRP Report 279, TRB, November 1985, the right - turn lane is not required. Due to the anticipated lot,, volumes, a. right -turn lane is not recommended. The City of Fort Collins. will have the final determination on this matter. Figure 2 shows the results of the trip assignment at the access intersection in the long range future (2010). The operation of this intersection is shown in Table 3. Calculation sheets are provided in Appendix B. t,Ji th a combined right-turn/left-turn lane, the exits from this property will operate unacceptably. The unacceptable operation is due to the volumes on Shields, rather than the egress. i ng traffic from the Vet C1 i n i c Road. Separating the right and left turns. will confine the delays to only the left -turning vehicles and allow the right turns to operate acceptably. However, due to the anticipated low volume_., separate right- and left - turn lanes are not recommended. Unacceptable operation during the peak hours. at stop sign controlled intersec- tions with arterial streets is not uncommon. Signali- zat i on is neither warranted or recommended at this location. Hepp 1 evih i to Court, an extremely long cul-de-sac to the viest of the subject property, could potentially be connected to this. access. However, the need for the connection would appear to be with the residents. of Heppl et,,lh i to Court. A second means of access to Hepp 1 et,.ih i to Court would make emergency access easier and give the res-i dents an al ternat i ve means of access to the arterial system. A sight distance analysis to the south of the t./et Clinic Road was conducted since Shields Street drops off to the south approximately 200 feet south of the site. Figure 3 shot,.is the results of that analysis. It t,aas concluded that there t,iill be adequate sight distance of 500 feet (Fort Col 1 i ns arterial standard at 50 mph) to the south when Shields Street is bu i 1 t as shot,,tn on the profile prepared by James H. Steulart & Associates, Consulting Engineers. Erased upon the profile data available, there is also adequate sight distance t,.l i th the existing profile of Shields Street with a design speed of 50 mph. is Land Use Vet Clinic g C.U.
