RECOMMENDATIONS/CONCLUSIONS ; Based on the findings of these technical analyses, recommen- dations for required roadway improvements can be identified. These recommendations account for development within Wildflower Ridge and Fox Hills. The following is a''brief summary of the above findings N i and a general description of the recommended improvements for the analyzed elements of the roadway network serving Wildflower Ridge and Fox Hills. i In the short range future (1995) with full development of Wildflower Ridge and Fox Hills, a westbound left -turn lane is i 61 required on CR 38E at the Red Fox Road intersection: No other auxiliary lanes are recommended. All traffic movements are expected to operated:at level of service A under both short and long term conditions.' This will t � provide excellent operating conditions. i - No specific improvements are appropriate on Red Fox Road given the distribution of residential traffic to a number of access rr i 1.' 1 L. points. Site traffic is not anticipated to noticeably impact the E� CR 38E/Taft Hill Road interse, ction given the moderate volume of t s 6 .I Table 2 Short and Long Tertn Peak Hour operations Levels of Service 1995 2010 Intersection AM PM AM PM CR 38E/Red Fox (stop sign) NB LT A A A A NB RT A A A A WB LT A A A A i i _ -4- 0/95 C.R. 38E 15/15 0/297 -l- 2/2:: i .. �-4* N t x 0 � //////'L'''�� c LEGEND: SITE TRAFFIC / TOTAL TRAFFIC r � r AM PEAK HOUR 4 - -F- 0/248 `.

These volumes were developed using the same 4 procedure by which the 1995 volumes were developed. Long range j site and background peak hour volumes are shown on Figure 5. i l;'• IV. TRAFFIC IMPACTS I Using the traffic volumes shown on Figures 4 and 5, the CR 38E/Red Fox Road intersection operates acceptably during the peak hours. These results are shown in Table 2. Calculation forms are 1. provided in the Appendix. Auxiliary lanes at the CR 38E/Red Fox Road intersection were evaluated using criteria in the _Larimer E i' County Access Policy. Average peak hour traffic volumes were determined by summing the morning and afternoon volumes and dividing by two. Based upon these criteria, a westbound left -turn lane is required on CR 38E at the Red Fox Road intersection. With a posted 45 mph speed limit, this lane should be 400 feet (deceler- ation and storage) and a bay taper at 15:1. In order to provide a smooth redirection from one lane to a two lane cross section and back to one lane, a 40:1 transition should be used. An eastbound r � s.' right -turn deceleration lane is not required. Although the right- r turn exits from Red Fox Road indicate the need for an acceleration lane according to the access policy, this acceleration' lane is not recommended. This recommendation is made in consideration of the driveways and intersecting strieets to the east on both'sides of.CR 38E. A safer environment will be created if exiting vehicles are 5 [i F C.R. 38E 0/68 /-15/15 0/212 —I" '**] r 2/2' ---- �k LO C14 Lo C'4 x 0 LL Uj w LEGEND: SITE TRAFFIC TOTAL TRAFFIC AM PEAK HOUR d 0/177 /— C.R. 38E 53/53 0/17)6/6 N I rn Lo Lo C4 x o U.

This study. evaluates the cross section of CR 38E and! the need for auxiliary lanes at the CR 38E/Red Fox Road intersection. D. Trip Distribution Trip distribution was derived using the existing relationship i of the turning movements at the CR 38E/Highland West intersection. ! The distribution from Wildflower Ridge and Fox Hills was assumed lv to be similar to the existing distribution (East - 90%, West - i: 10%). � I E. Traffic Assignments and Volumes i Utilizing the trip generation estimates and the distribution assumptions identified previously, projected vehicle trips were assigned to the street system. Figure 4 shows the short range (1995) peak hour traffic assignment for the site generated traffic and the background traffic with a single point of access (Red Fox Road) to CR 38E. Red Fox Road will be fed by a system of local streets, each serving an estimated 5 - 15 dwelling units. Accord- ingly, each local street intersection with Red Fox Road will accommodate minimal traffic volumes. Once on CR 38E, most of the site traffic will turn onto Taft Hill Road.

FUTURE TRAFFIC PROJECTIONS A. Development Assumptions A short range future (1995) access scenario was analyzed. The short range future included the existing traffic factored by G a 2-3 percent per year growth factor, plus the proposed development traffic. It was assumed that Wildflower Ridge and Fox Hills would be fully built out by 1995. This assumption is subject to market 5 demands for this type of residential use. The increase in background traffic in this area: is largely due to other development AI Hi in the area, primarily to the west. B. Site Trip Generation r- f � To estimate the traffic generated by the proposed development, i standard trip generation rates compiled by the Institute of i..! Transportation Engineers in their report entitled Trip Generation, Fifth Edition were utilized for single family detached residential land uses. These rates were applied to determine daily, AM, and C I PM peak hour traffic volumes expected to be generated by the site. Table 1 shows that WildfloweriRidge and Fox Hills would generate approximately 830 trips per day with 64 and 87 trips occurring during the AM and PM peak hour periods, respectively.

Taft Hill Road (CR 19) is a north/south arterial in Fort Collins and a major travel route between Loveland and Fort I Collins. It is a two lane paved roadway. CR 38E has a posted k speed limit of 45 miles per hour. CR 38E is under, stop sign control at Taft Hill Road at the current time. However, the intersection will be under traffic signal control in the fourth quarter of 1993. i B. Existing Traffic Condition's r Peak hour counts were conducted at the CR 38E and Highland West intersection, just east of the proposed site. These counts revealed 250-270 vehicles using CR 38E during peak hour periods. The average daily traffic on CR 38E in 1991 was 3,900 vehicles. Peak hour counts are shown on Figure 3. C. Surrounding Land Uses The residential development is proposed to be built on land i. that is in agricultural use. Land west and south of Wildflower Ridge and Fox Hills is also d n agricultural use. Taft Canyon residential development is east of the site. I+ r. C ! E: C i 2 W. COUNTY ROAD 3SE Owe t WAY W LDF R ID E On a Oc OAY 0.1 0 0 LL Uj M �l FC X HILLS P.U.D.

INTRODUCTION h Wildflower Ridge Subdivision and Fox Hills PUD are. residential developments proposed to be 'located just south of 'CR 38E and IJ approximately 0.65 miles west of Taft Hill Road in Larimer County, Colorado. The site location is shown in Figure 1. r„ I; The proposed Wildflower Ridge and Fox Hills developments have l 87 single family detached dwelling units. Figure 2 shows a I., schematic of the site plan. The site plan shows one access to the public road system. This main access will be from CR 38E via Red Fox Road. A secondary access Will be via a meandering local street system through Taft Canyon connecting to Taft Hill Road. This traffic analysis evaluates a single point of access (38E via Red i. Fox Road) since the route through Taft Canyon is considered to be too circuitous. Two future conditions were evaluated: a short range (1995) future condition and a long range (2010) future condition. The focus of thisreview is the roadway cross section requirements, geometric improvements at key intersections, and ltraffic control measures at these intersections. II. EXISTING CONDITIONS r.. ni A.
