Planners. Landscape Architects. 10212 Governor Lane Blvd, Suite 1007 Williamsport, Maryland 21795 T 301.223.5010 F 301.223.6831 September 4, 2008 OVERVIEW Report Summary Patton Harris Rust Associates (PHR +A) has prepared this document to present the traffic impacts associated with the proposed Bums Valley Mill Road development to be located along the east of Valley Mill Road (VA Route 659), north of Martin Lane, in Frederick County, Virginia. The proposed development is to include a 3,500 foot fast -food restaurant with drive -thru. Access will be provided via Martin Lane located along the east side of the Valley Mill Road. The proposed development will be built -out over a single transportation phase by the year 2010. Analyses are provided for existing, 2010 background and 2010 build -out year conditions. Figure 1 is provided to illustrate the location of the proposed Burns Valley Mill Road development with respect to the surrounding roadway network. Methodology The traffic impacts accompanying the Burns Valley Mill Road development were obtained through a sequence of activities as the narratives that follow document: Assessment of background traffic including other planned projects in the area of impact, Calculation of trip generation for the proposed Burns Valley Mill Road development, Distribution and assignment of the Burns Valley Mill Road development- generated trips onto the completed roadway network, Analysis of capacity and level of service using the latest version of Synchro 7 for existing and future conditions. A Traffic /mpact Analysis of Burns Valley Mill Road Project Number: 15877 -1 -0 September 4, 2008 Page 1 F P HRA Figure 1 Vicinity Map: Burns Valley Mill Road, in Frederick County, VA A Traffic Impact Analysis of Burns Valley Mill Road Project Number: 15877 -1 -0 September 4, 2008 Page 2 EXISTING CONDITIONS PHR +A conducted weekday AM/PM and Saturday mid -day peak hour manual turning movement counts at the intersection of Route 7 (Berryville Pike)/I-81 Route 7 (Berryville Pike) /I -81 NB Rampslvalley Mill Road, Route 7 SB Ramps, (Berryville Pike) /Martin Lane, Route 7 (Berryville Pike) /Gateway Drive, Valley Mill Road /Dairy Corner Place and Valley Mill Road /Martin Lane. In order to determine the ADT (Average Daily Trips) along the study area roadway links, "k" factor (the ratio of PM peak hour traffic volumes to 24 -hour traffic volumes) of 7.7% was utilized based upon the published Virginia Department of Transportation (VDOT) 2006 traffic count data. Figure 2 shows the existing weekday and Saturday ADT as well as weekday AM/PM peak hour and Saturday mid -day peak hour traffic volumes at key locations within the study area. Figure 3 shows the existing lane geometry and weekday AM /PM peak hour and Saturday mid -day peak hour levels of service. Existing condition analysis is based upon VDOT signal dining. PHR +A has provided Table 1 to show the existing weekday AM /PM and Saturday mid -day peak hour levels of service and 95t percentile back of queue for each lane group. All traffic count data and Synchro level of service worksheets are included in the Appendix section of the report.

PHR+A utilized the trip distribution percentages shown in Figure 6 to assign the proposed Burns Valley Avenue development trips (Table 3) throughout the study area roadway network. Figure 7 shows the developmen generated AM/PM peak hour and Saturday mid -day peak hour trips and ADT assignments. The Burns Valley Mill Road assigned trips (Figure 7) were added t0 the 2010 background traffic volumes (Figure 4) to obtain 2010 build -out conditions. Figure 8 shows the 2010 build -out weekday and Saturday ADT as well as weekday AM /PM peak hour and Saturday mid -day peak hour traffic volumes at key locations throughout the study area network. Figure 9 shows the respective 2010 build -out lane geometry and weekday AM/PM peak hour and Saturday mid -day peak hour levels of service. Table 4 shows the 95 percentile back of queue and levels of service for each lane group during 2010 build out conditions.

The following describes the improvements suggested for each of the study area intersections to maintain acceptable levels of service or better during 2010 build -out conditions: Route 7 (Berryville Pike)/I -81 NB Ramps /Valley Mill Road: This intersection will require a westbound through lane, a northbound left -turn lane and a southbound left turn lane. (Suggested improvements are necessary without the proposed Burns Valley Mill Road development to maintain levels of service "C NOTE: Funding source for the aforementioned improvements have yet to be identified. The applicant will work with VDOT /County to accommodate pedestrian and bicycle facilities adjacent to the site.
