Surveyors. Planners. Landscape Architects. 208 Church Street, S.E. Leesburg, Virginia 20175 T 703.777.3616 F 703.777.3725 September 8, 2004 (Original Submission: June 14, 2009) OVERVIEW Report Summary Patton tHarris Rustj& Associates, pc (PHR +A) has prepared this document to present the traffic impacts associated with the proposed Butcher Property to be located at the end of Farmington Boulevard, east of Greenwood Road (Route 656), in Frederick County, Virginia. The proposed project will include a total of 69 residential units with sole access provided via Farmington Boulevard. Built -out will occur over a single phase by the year 2008. PHR +A has provided Figure 1 to illustrate the location of the Butcher Property with respect to the surrounding roadway network. The study area encompasses Greenwood Road from Valley Mill Road (Route 659) to Route 657. Methodology The traffic impacts accompanying the Butcher Property site 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 the Butcher Property trip generation, Distribution and assignment of the Butcher Property generated trips onto the completed road network, Analysis of capacity and levels of service using the newest version of the highway capacity software, TICS -2000, for existing and future conditions. EXISTING CONDITIONS PHR +A conducted AM and PM peak hour manual turning movement counts at the intersections of Greenwood Road Valley Mill Road and Greenwood Road/ Route 657. In order to determine the ADT (Average Daily Traffic) along the study area roadway links, a "k" factor (the ratio of PM peak hour traffic volumes to 24 -hour traffic volumes) of 10% was assumed. Existing traffic volumes were obtained along Farmington Boulevard (Briarwood Subdivision Estates) based upon trip generation results for 88 existing single family detached residential units as calculated using the 7 Edition of the histitute of Transportation Engineers' (ITE) Trip Generation Report. Table 1 is provided to show the existing trip generation results along Farmington Boulevard. All count data are provided in the appendix section of this report.

P1-IR HA increased the existing traffic volumes along Greenwood Road, Route 657 and Valley Mill Road (west of Greenwood Road) using a conservative growth rate of five percent (5%) per year through Year 2008. Additionally, all trips relating to specific future "other developments" located along Charming Drive and Valley Mill Road were included. The following approved, but not yet completed, "other developments" were considered: Toll Brothers; Charming Drive Residential; Giles Farm; Fieldstone; Abram's Pointe (Including Coventry Court Subdivision). Note: Coventry Court trips combined with Abrams Point are consistent with the revised Master Development Plan.

Table 3 shows the trip generation results for the proposed Butcher Property site.

Figure 6 represents the distribution percentages for trips produced by and attracted to the Butcher Property development. Figure 7 shows the respective development generated AM/PM peak hour trips and ADT assignments at key locations within the study area. 2008 BUILD -OUT CONDITIONS The Butcher Property assigned trips (Figure 7) were added to the 2008 background traffic volumes (Figure 4) to obtain 2008 build -out conditions. Figure 8 shows the 2008 build -out ADT and AM/PM peak hour traffic volumes at key locations throughout the study area. Figure 9 shows the respective 2008 build -out lane geometry and AM/PM peak hour levels of service. All HCS -2000 levels of service worksheets are included in the Appendix section of this report. CONCLUSION The traffic impacts associated with the Butcher Property development are acceptable and manageable. All study area intersections will maintain acceptable overall levels of service "D" or better for 2008 build -out conditions. The intersection of Greenwood Road Valley Mill Road will require traffic signalization, however, this will be required with or without the proposed development.
