Surveyors. Planners. Lcrdsccp e Architects. 10212 Governor Lane Blvd. Suite 1007 Williamsport, MD21795 T 301.223.4010 F 301.223.6831 August 14, 2008 EXECUTIVE SUMMARY Patton Han Rust Associates (PHR +A) has prepared this document to present the traffic impacts associated with the proposed Governors Hill development located along the south side of Route 50 (Millwood Pike), between Prince Frederick Drive and Victory Road, in Frederick County, Virginia. The proposed development is comprised of 128 multi family units, 422 townhouse units, 385,000 square feet of office and 900,000 square feet of shopping center. Build -out is anticipated to occur over two (2) transportation phases by the Year 2025. Phase 1 is to be built -out by Year 2015 and it assumes a partial build out of the development to include: 128 multi- family units, 422 townhouse units, and 400,000 square feet of shopping center. Access will be provided via Coverstone Drive (future roadway) located along the south side of Route 50, opposite Inverlee Way. Phase 2 will be build -out by Year 2025 and it assumes the full build -out of the proposed Governors Bill development. Analysis is provided for the "Proposed Scenario" Scenario #1 during Phase 2. This scenario assumes the full build -out with access to be provided via Coverstone Drive (future roadway) located along the south side of Route 50, opposite Inverlee Way. Per scoping agreement with the Virginia Department of Transportation (VDOT), PHR +A has provided two (2) additional scenarios during Phase 2 (Year 2025): "VDOT /County Requested" Scenario #2 assumes the full build -out with access to be provided via Tazewell Drive (future roadway) located along the south side of Route 50, opposite Sulphur Springs Road and "VDOT /County Requested" Scenario #3, a combination of the two (2) aforementioned scenarios, assumes the full build -out with access to be provided via both Coverstone Drive and Tazewell Drive located opposite Inverlee Way and Sulphur Springs Road, respectively. PHR +A has provided the analyses for the "Proposed Scenario" #1) as well as for the "VDOT /County Requested" Scenarios #2 #3). Based upon Synchro analysis results, assuming the suggested improvements, all the study area intersections will maintain levels of service "C" or better during Phase 1 2015 build -out conditions and "D" or better during "Proposed Scenario" Scenario #1 and "VDOT Requested" Scenarios #2, #3 during Phase 2 2025 build -out conditions. Although PHR +A has provided analyses for two (2) VDOT /County requested transportation scenarios, the "Proposed Scenario which does NOT include access opposite Sulphur Springs Road, is presented as the preferable site access condition. The shift of the entrance is to allow for a safer traffic movement at the newly proposed entrance location. This site driveway depicted for the "Proposed Scenario" opposite Inverlee Way would adequately serve as a surrogate for the connection opposite Sulphur Springs Road in providing a southern connection from Route 50 to Route 522. In fact, the Inverlee Way connection was the initial concept for the project in Year 2005, which at the time was fully supported by VDOT /County, however, the land necessary to make the connection was not yet available to the Applicant. Consequently, the connection opposite Sulphur Springs was contemplated (and added to the Comprehensive Plan) in -lieu of the Inverlee Way connection. The Applicant has now acquired the land needed to make the Inverlee Way connection and wishes to proceed with the project as it was originally envisioned by the Applicant, VDOT and the County.

Figure 1 is provided to illustrate the location of the proposed Governors Hill Development with respect to the surrounding roadway network. Methodology The traffic impacts accompanying the Governors Hill 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 Governors Hill Development, Distribution and assignment of the Govemors Hill Development generated trips onto the completed roadway network, Analysis of capacity and level of service using the Synchro 7 for existing and future conditions. A Tragic Impact Analysis of Governors Hill Development Project Number: 13415 -1 -3 August 14, 2008 Page 2 Assumptions The following assumptions are incorporated in the analysis based upon the scoping session between the Virginia Department of Transportation (VDOT) and PFIR +A. 3% growth rate along Sulphur Springs Road and 2% growth rate along Route 50 and Route 522, respectively, per year through year 2015 (Phase 1). 2% growth rate along Sulphur Springs Road and 1% growth rate along Route 50 and Route 522, respectively, from year 2015 through year 2025 (Phase 2). Future re- alignment of the intersection of Route 522 and Route 50.

PHASE 2 2025 BACKGROUND CONDITIONS PHR +A has provided analysis for the "Proposed Scenario" Scenario #1. This scenario assumes the full build -out with access to be provided via Coverstone Drive (future roadway) located along the south side of Route 50 (Millwood Pike), opposite Inverlee Way. Per scoping agreement with the Virginia Department of Transportation (VDOT), Analyses are provided for two (2) additional scenarios: "VDOT /County Requested" Scenario #2 assumes the full build -out with access to be provided via Tazewell Drive (future roadway) located along the south side of Route 50 (Millwood Pike), opposite Sulphur Springs Road and "VDOT /County Requested" Scenario #3, a combination of the two (2) aforementioned scenarios, assumes the full build -out with access to be provided via both Coverstone Drive and Tazewell Drive located opposite Inverlee Way and Sulphur Springs Road, respectively. To obtain 2025 base conditions, PHR +A applied annual growth rates of three percent (3 to the existing traffic volumes along Sulphur Springs Road and two percent (2 to the existing traffic volumes along Route 50 and Route 522, respectively, per year through year 2015. Annual growth rates of 2% and 1% were applied to Sulphur Springs Road and Route 50/Route 522, respectively, from year 2015 through year 2025. Additionally, all trips relating to specific future "other developments" located within the vicinity of the proposed development were included. Using the 7 Edition of ITE's Trip Generation Report, PHR +A has provided Table 6 to summarize the 2025 "other development" trip generation.

Figures 13a through 13e show the corresponding development generated weekday AM/PM peak hour trips and ADT as well as Saturday mid -day peak hour trips and ADT. 2025 BUILD -OUT CONDITIONS The Governors Hill assigned trips (Figures 13a -13c) were added to the Phase 2 2025 background traffic volumes (Figures 10a-10c) to obtain Phase 2 2025 build -out conditions. Figures 14a through 14c show the Phase 2 2025 build -out weekday ADT and AM/PM peak hour traffic volumes as well as Saturday ADT and mid -day peak hour traffic volumes at key locations throughout the study area for Scenarios 1, 2 and 3, respectively. Figures 15a through 15c show the respective weekday AM /PM peak hour and Saturday mid-day peak hour levels of service and lane geometry. PHR +A has provided Tables 9a through 9c to show the Phase 2 2025 build -out levels of service and 95 percentile back of queue for each lane group for Scenarios 1, 2 and 3, respectively.

Based upon Synchro analysis results, assuming the suggested improvements, all the study area intersections will maintain levels of service "C" or better during Phase 1 2015 build -out conditions and levels of service "D" or better during "Proposed Scenario" Scenario #1 and "VDOT Requested" Scenarios #2, #3 during Phase 2 2025 build -out conditions. The following describes the improvements suggested for the study area intersections during Phase 1 2015 build -out conditions: Phase 1 (2015) Route 50/Inverlee Way /Coverstone Drive: Signalization, one eastbound left turn lane and right -turn lane, two (2) westbound left -turn lanes and 4 leg in northbound direction will be required. Route 50/Victory Road: Signalization will be required. Exhibit A is provided in the Appendix section of this report to show the detailed diagram of the intersections with suggested improvements. The following describes the improvements suggested for the study area intersections during 2025 build -out conditions for each scenario: Phase 2 (2025) "Proposed Scenario Scenario #1 (access via Coverstone Drive opposite Inverlee Way): Route 50 /Prince Frederick Drive /Custer Avenue: Northbound re- striping and one northbound left-turn lane will be required. Prince Frederick Drive /Costello Drive: Signalization, one northbound left -turn lane and one southbound right -turn lane will be required. Route 50/Inverlee Way /Coverstone Drive: Signalization, one eastbound left- turn lane and right -turn lane, two (2) westbound left-turn lanes, and 4 leg in northbound direction will be required. Route 50 /Sulphur Springs Road: One southbound left-turn lane will be required. Route 50 /Victory Road: Signalization will be required.

"VDOT /Corurty Requested Scenario #2 (access via Coverstone Drive Opposite Sulphur Springs Road): Route 50/Prince Frederick Drive /Custer Avenue: One eastbound right -turn lane, northbound re- striping and one northbound left -ttm) lane will be required. Prince Frederick Drive /Costello Drive: Signalization, one northbound left -turn lane, one southbound through lane as well as one right -turn lane will be required. Route 50 /Sulphur Springs Road /Coverstone Drive: One eastbound left -turn lane, one eastbound right -tum lane, two (2) westbound left -turn lanes, one southbound left -turn as well as one right -turn lane and 4 leg in northbound direction will be required. Route 50/Victory Road: Signalization will be required. VDOT /County Requested Scenario #3 (access via Coverstone Drive Tazewell Drive): Route 50/Prince Frederick Drive /Custer Avenue: One northbound left -turn lane and northbound re- striping will be required. Prince Frederick Drive /Costello Drive: Signalization and one northbound left turn lane will be required. Route 50 /Inverlee Way Coverstone Drive: Signalization, one eastbound left turn lane, one eastbound right -turn lane, one westbound left-turn lane and 4 leg in northbound direction will be required.

This is primarily due to the prohibitive costs associated with overcoming the grade and alignment constraints at Sulphur Springs Road. Additionally, the site driveway depicted for the "Proposed Scenario" opposite Inverlee Way would adequately serve as a surrogate for the connection opposite Sulphur Springs Road in providing a southern connection from Route 50 to Route 522. In fact, the Inverlee Way connection was the initial concept for the project in Year 2005, which at the time was fully supported by VDOT /County, however, the land necessary to make the connection was not yet available to the Applicant. Consequently, the connection opposite Sulphur Springs was contemplated (and added to the Comprehensive Plan) in -lieu of the Inverlee Way connection. The Applicant has now acquired the land needed to make the Inverlee Way connection and wishes to proceed with the project as it was originally envisioned by the Applicant, VDOT and the County. The applicant will work with VDOT /County to accommodate pedestrian and bicycle facilities adjacent to the site. NOTE: Funding source for the improvements have yet to be identified.
