The proposed rezoning application for the 370.02+ acre subject properties has been designed to implement the land use, transportation, public utilities and public facilities needs identified in the Round Hill Community Land Use Plan Therefore, the Applicants rezoning application is in conformance with the Comprehensive Policy Plan. Existing Conditions The subject properties consist primarily of open fields and woodlands with rolling and moderately sloped terrain. These properties are not in active agricultural land use and are primarily unimproved with the exception of two residential structures that are utilized as rental units, a small commercial structure that was previously utilized as a radio station, and the foundation and some side walls of a large residential structure that appears to have been constructed prior to 1937 and has been dilapidated since 1950. All of these structures will be removed over the course of development of the subject properties to accommodate the construction of internal road systems and commercial and office land bays. All existing structures will be permitted with the Frederick County Building Inspections Department to ensure that asbestos inspections and removal occurs and that all necessary measures are accomplished prior to demolition. The subject properties are identified on FEMA NFIP Maps 510063- 0105 -B and 510063 0115-B. FEMA NFIP Map 510063 -0115B indicates that floodplain areas exist on tax parcels 52- ((A)) -C and 52- ((A)) -50, totaling approximately 1 30.67 acres. These floodplain areas are located in the central portion of the overall site development area and are associated with a large drainage area, which goes under Northwestern Pike to Abram's Creek. The conceptual land plan directs land bay development away from the floodplain areas; however, some impacts to this environmental feature will be realized through the construction of the east -west collector road identified within the Comprehensive Policy Plan Round Hill Land Use Plan. Additionally, minor impacts will occur within the identified floodplain area necessary to implement regional stormwater management, as well as a recreational trail system proposed within the park area identified around the pond near Northwestern Pike. The projected impacted floodplain areas will be provided on the Master Development Plan to ensure compliance with County ordinance requirements.

The Applicants have conducted a detailed Wetlands Delineation Study prepared by Greenway Engineering, dated November 6, 2007 for the entire project site. The Applicants have received a Jurisdiction Determination Letter from the U.S. Army Corp of Engineers, which identifies the approved wetland areas on the subject properties. These areas are delineated on the Silver Lake, LLC Property Environmental Features Map Exhibit that is included with this analysis. Additionally, a copy of the Wetlands Delineation Study and the Jurisdiction Determination Letter has been included with this analysis. The projected impacted wetlands areas will be provided on the Master Development Plan to ensure compliance with all Federal, State, and local requirements. Steep Slopes The subject properties contain minor areas of steep slope as defined, which are located primarily along the defined floodplain areas located within the central portion of the site. It is anticipated that there will be minor impacts within the defined steep slope areas primarily due to the construction of public utilities. The projected impacted steep slope areas will be provided on the Master Development Plan to ensure compliance with County ordinance requirements. The subject properties have pronounced slopes located primarily is the northern portion of the site in the area that will be developed as a Continuing Care Retirement Community (CCRC). These areas do not meet the County definition of steep slopes; however, substantial filling will need to occur within the disturbed portions of these slopes to accommodate the CCRC. All areas of compacted fill will be certified through geotechnical analysis during the site development process and all reports will be furnished to the County for verification of this work. Mature Woodlands Silver Lake, LLC Rezoning The subject properties are predominately covered with mature woodlands located within the northern, central, and eastern portions of the 370.02± acre site. The conceptual land plan for the subject properties identifies areas in which mature woodlands can be preserved, which include buffer areas, floodplain areas, and substantial areas within the proposed Continuing Care Retirement Community (CCRC) area. The Frederick County Zoning Ordinance allows for disturbance of mature woodland areas to implement planned development areas within the Sewer and Water Service Area (SWSA) and establishes replanting requirements to mitigate this impact. Therefore, the Applicants will be able to address these requirements and will identify the location of mature tree preservation areas on the Master Development Plan.

These soil types exist primarily in the northern and western portions of the subject site. The proposed development plan identifies these areas for commercial land use and the CCRC land use. Table 10 of the Soil Survey identifies all soil types as moderate to severe for the development of roads and commercial structures due to shrink -swell potential and soil strength. Soils testing and compaction testing are standard practice for development projects and road construction; therefore, reports verifying soils suitability will be conducted throughout the development of the subject site. The soil types are associated with limestone geology, which underlies the subject properties. Limestone geology needs to be treated with care during site development to ensure that solution channels and sinkholes are identified prior to site disturbance and are designed to prevent infiltration of pollutants. The Applicant will incorporate narratives on the Master Development Plan that commit to geotechnical analysis during the site plan process to determine the location of sink holes, solution channels and other karst features and submit reports to the County Engineer for review and approval of the proposed treatment of these features as a condition of land disturbance.

The majority of the active orchards in proximity to this site are owned and operated by Fruit Hill Orchard who operates an existing wastewater pond immediately north of the subject properties. The development of the proposed Continuing Care Retirement Community (CCRC) will occur near this wastewater facility; therefore, development plans will include the preservation of perimeter mature woodlands and established grading limits to ensure that there is no impact to this facility as a result of the development of this site. TRANSPORTATION Silver Lake, LLC Rezoning The 370.02* acre subject site has approximately 2,400 linear feet of frontage along Northwestern Pike (U.S. Route 50) and approximately 1200 linear feet of frontage along Poor House Road (Route 654). The Round Hill Land Use Plan recommends regional transportation improvements along the Northwestern Pike corridor, as well as on the north side of this corridor that traverse the subject site. The Round Hill Land Use Plan recommends travel lane and signalization needs associated with development in the study area; however, this has not been quantified through traffic modeling based on various land use assumptions. Therefore, the Applicants have prepared a detailed traffic impact analysis statement in order to determine the projected impacts associated with the proposed development of a CCRC and commercial retail and office land use on the subject site. File 44928S 6 Greenway Engineering Silver Lake, LLC Rezoning A Traffic Impact Analysis (TIA) has been prepared for the Silver Lake, LLC properties by Patton Harris Rust Associates, dated November 25, 2008, which is included as a component of the Impact Analysis Statement. The TIA assumes the total build -out of the Continuing Care Retirement Community (CCRC); 583,050 square feet of commercial retail; and 494,600 square feet of office land use that is developed over a four -phase study. The TIA studies turning movements and capacities at five intersections along the Northwestern Pike (U.S. Route 50 West) corridor, as well as the northbound and southbound on and off ramps at the Route 37 interchange. The TIA provides for a Level of Service (LOS) analysis for AM and PM peak hour weekday and Saturday traffic volumes, as well as Average Daily Trip (ADT) volumes for existing, background, and build -out conditions for each transportation phase. Additionally, the TIA provides recommended improvements to the regional transportation network that will mitigate the impacts associated with the build -out of the 370.02+ acre properties and improve the LOS at all studies intersections, which are the result of background traffic impacts. Phase 1 of the TIA accounts for background projects agreed upon during the project scoping with VDOT and Frederick County, and includes the development of 570 units within the CCRC and 180,000 square feet of commercial retail on the 370.02+ subject site. The TIA modeling demonstrates that deficiencies occur at several of the intersections due primarily to existing traffic and projected background traffic conditions. The TIA provides for suggested improvements to the regional transportation network during the Phase 1 development of the subject site to create acceptable LOS at these intersections. These improvements include new traffic signalization at the intersection of Northwestern Pike and Poor House Road, new traffic signalization and turn lane improvements at the intersection of Northwestern Pike and Spinning Wheel Lane, and improvements to the Route 37 southbound off ramp to establish a free flow right turn condition onto Northwestern Pike. Phase 2 of the T1A builds on the assumptions utilized in Phase 1 through a 2% annualized increase in traffic volumes within the study area through the year 2018. Additionally, Phase 2 increases development on the 370.02+ acre subject site to account for an additional 170,000 square feet of commercial retail and 105,000 square feet of office land use. The TIA modeling demonstrates that deficiencies occur at two of the intersections not impacted during the Phase 1 analysis. The TIA provides for suggested improvements to the regional transportation network during the Phase 2 development of the subject site to create acceptable LOS at these intersections. These improvements include new signalization and turn lane improvements at the intersection of Northwestern Pike and Silver Lake Road, the development of a two -lane east -west road system that connects Spinning Wheel Lane to Retail Boulevard, improvements to the Route 37 northbound off ramp to provide for a second right turn lane, and the development of a third westbound travel lane on Northwestern Pike under the Route 37 bridge structure. Phase 3 of the TIA builds on the assumptions utilized in Phase 2 through a 2% annualized increase in traffic volumes within the study area through the year 2020. Additionally, Phase 3 increases development on the 370.02+ acre subject site to account for an File 44928S 7 Greenway Engineering SEWAGE CONVEYANCE AND TREATMENT Q 700 gallons /day /acre Q 700 GPD x 370.02+ acres Q 259,014 GPD projected at project build -out Silver Lake, LLC Rezoning additional 140,000 square feet of commercial retail and 245,000 square feet of office land use. The TIA does not demonstrate additional deficiencies at any of the intersections within the study area. The 'HA provides for two suggested improvements to the regional transportation network during the Phase 3 development of the subject site. These improvements include the provision of a second right turn lane on Spinning Wheel Lane at the intersection of Northwestern Pike, and the extension of the east -west road system to connect with Poor House Road (Route 654). Phase 4 of the TIA builds on the assumptions utilized in Phase 3 through the build -out of background projects agreed upon during the project scoping with VDOT and Frederick County, a 2% annualized increase in traffic volumes within the study area through the year 2022, and includes the complete build -out of the CCRC and the complete build -out of the commercial and office center, accounting for an additional 93,050 square feet of commercial retail and 144,600 square feet of office land use on the 370.02+ subject site. The TIA does not demonstrate additional deficiencies at any of the intersections within the study area. The TIA provides for four suggested improvements to the regional transportation network during the Phase 4 development of the subject site. These improvements include the provision of a second left turn lane on Silver Lake Road at the intersection of Northwestern Pike, the provision of a second left turn lane on Botanical Boulevard at the intersection of Northwestern Pike, the development of a third westbound travel lane on Northwestern Pike between Silver Lake Road and Poor House Road, and the development of a third eastbound travel lane on Northwestern Pike from Retail Boulevard through the Route 37 overpass bridge. The 370.02+ acre subject property is located within the Round Hill Community Sewer and Water Service Area (SWSA). A public sewer system including a sewer pump station and 8" sanitary sewer force main exists to the east of the subject property, which serves the existing commercial development on the north side of Northwestern Pike (U.S. Route 50 West). Analysis of this system indicates that there is sufficient capacity to serve the CCRC and commercial land uses identified in the Phase 1 portion of the traffic impact analysis statement. The Applicant has worked with the Director of the Frederick County Sanitation Authority (FCSA) to determine the projected needs and collection system requirements for the remaining phases of development identified in the traffic study for the subject property, as well as the needs for the Round Hill Community Based on comparable discharge patterns, the Frederick County Sanitation Authority (FCSA) has determined that 700 gallons /day per acre is a reasonable guide for estimating the sewer impact for the commercial, office and CCRC land uses. File #4928S 8 Greenway Engineering WATER SUPPLY Q 1,000 gallons /day /acre Q 1,000 GPD x 370.02± acres Q 370,020 GPD projected at project build -out Silver Lake, LLC Rezoning The proposed build -out of the 370.02± subject property is estimated to add 259,014 gallons per day to the public sewage conveyance system. The development of land uses in the first phase will direct effluent to the Opequon Water Reclamation Facility (OWRF) through the existing pump station and sewer force main system. The design capacity of the treatment plant is 8.4 million gallons per day (MGD) during summer months and 16.0 MGD during winter months, of which approximately 6.8 MGD of capacity is currently being utilized. The Applicant will work with the FCSA on all agreements necessary to implement the regional infrastructure sufficient in size and capacity to serve the 370.02+! site and the Round Hill Community. This regional infrastructure will include on -site collection systems that transfer sewer through gravity, pump stations, and force mains routed along the Abram's Creek drainage area that provide conveyance to the Parkins Mill Wastewater Treatment Facility. The Parkins Mill Wastewater Treatment Facility is currently under expansion to create a 5- million gallons per day (MGD) facility. The 5 MGD expansion of the Parkins Mill Wastewater Treatment Facility is projected to be complete in 2009, which will provide adequate capacity for sewage treatment. The Applicant direct all effluent from the 370.02+ acre site to the Parkins Mill Wastewater Treatment Facility upon completion of the regional infrastructure improvements described above. The 370.02+ acre subject property is located within the Round Hill Community Sewer and Water Service Area (SWSA). A public water system including a 20" water transmission line and a 4 MGD water storage tank exist to the north and east of the subject property, which serves the existing commercial development on the north side of Northwestern Pike (U.S. Route 50 West) Analysis of this system indicates that there is sufficient capacity to serve the CCRC and commercial land uses identified in the Phase 1 portion of the traffic impact analysis statement. The Applicant has worked with the Director of the Frederick County Sanitation Authority (FCSA) to determine the projected water capacity and fire flow needs for the remaining phases of development identified in the traffic study for the subject property, as well as the needs for the Round Hill Community. Based on comparable consumption estimates, the Frederick County Sanitation Authority (FCSA) has determined that 1,000 gallons /day per acre is a reasonable guide for estimating the water impact for the commercial, office and CCRC land uses. The figures below represent the impact that the total build -out of the proposed land uses will have on the water supply and treatment systems. File #4928S 9 Greenway Engineering The proposed build -out of the 370.021 subject property is estimated to require 370,020 GPD of public water service for the commercial, office and CCRC land uses. The FCSA water transmission system provides water service to this area of the community via the Stephens City quarry system from the James H. Diehl Water Filtration Plant and the Clearbrook quarry system from the North Water Filtration Plant. These systems currently provide 6.0 MGD and can be increased to 10 MOD. The Applicant will work with the FCSA on all agreements necessary to implement the regional infrastructure sufficient in size and capacity to serve the 370.021 acre site and the Round Hill Community. This regional infrastructure will include water transmission lines and elevated water storage that will accommodate the needs of the FCSA to service the portions of the Round Hill Community. The on -site water infrastructure required to convey potable water to the proposed commercial, office, and CCRC land uses will be developed by the Applicant to standards acceptable to the FCSA for future operation and maintenance. DRAINGE The 370.021 acre subject site is naturally divided into 3 distinctive drainage areas, which direct drainage from the north, east, and west towards the central portion of the site. The site directs drainage from the central portion of the site to the southeast to a large pond that is visible from Northwestern Pike (U.S. Route 50 West). The developed portions of the site for both the CCRC and the commercial retail and office land uses are proposed to be designed as a regional stonnwater management system. This system will include a series of smaller drainage structures and the large pond, which are designed to promote stormwater quality and quantity to meet State and local regulations. The general location of the structures that will be utilized for this regional system will be provided on the Master Development Plan for the subject site. The underlying limestone geology may require the design of impervious liners for the proposed regional stormwater management system to ensure that infiltration of stormwater and pollutants is avoided. The Applicant will incorporate narratives on the Master Development Plan that commit to geoteclmical analysis during the site plan process to determine the appropriate design measures for stoimwater management facilities that will be submitted to the County Engineer for review and approval prior to land disturbance activities. SOLID WASTE DISPOSAL Silver Lake, LLC Rezoning The impact on solid waste disposal facilities can be projected from an average annual business consumption of landfill volume of 5.4 cubic yards per 1,000 square feet of structural floor area and an average annual residential consumption of 5.4 cubic yards per household (Civil Engineering Reference Manual, 4 edition). The following figures File 44928S I0 Greenway Engineering Silver Lake, LLC Rezoning show the increase in average annual volume based on the 1,077,650 square feet of commercial and office land use, and the CCRC independent living, assisted care and skilled care residential units that are projected to develop over a 14 -year period: AV 5.4 Cu. Yd. per 1,000 square feet AV 5.4 Cu. Yd. x 1,077 (1,000 square feet) AV 5,815 Cu. Yd. at commercial build out /yr, or 4,070 tons /yr at build -out AV 5.4 Cu. Yd. per household AV 5.4 Cu. Yd. x 1,048 CCRC residential units AV 5,659 Cu. Yd. at CCRC build -out, or 3,961 tons /yr at build -out TOTAL AV 8,031 tons /yr 14 -yr build -out 573 ton annual increase at build out The Municipal Solid Waste area of the Regional Landfill has a current remaining capacity of 13,100,000 cubic yards of air space. The projected 14 -year build -out of the subject site will generate on average 573 tons of solid waste annually. This represents a 0.28% increase in the annual solid waste received by the Municipal Solid Waste area of the Regional Landfill, which currently averages 200,000 tons per year. The complete build -out of the commercial retail, office, and CCRC is projected to increase the solid waste received by the Municipal Solid Waste area of the Regional Landfill by 4.0% annually. The commercial retail, office, and CCRC land uses will utilize commercial waste haulers for trash pickup service; therefore, transportation and increased volume impacts at the citizen convenience centers will be mitigated and tipping fees will be generated that will create a continuous revenue source for the Regional Landfill by the proposed project. HISTORICAL SITES AND STRUCTURES The Frederick County Rural Landmarks Survey does not identify structures on the 370.02-acre site that are deemed potentially significant. Three sites within close proximity are identified as potentially significant, which include the Hodgson House #34 -93), the Hodgson -Abner House #34 -94), and Walnut Grove #34 -98); however, none of these sites are identified as properties that are potentially eligible for the state and national register of historic places. Additionally, the National Park Service Study of Civil War Sites in the Shenandoah Valley identifies the southwestern portion of the 2 Winchester Core Battlefield area (Phase 6) located adjacent to the subject site. The three sites identified above are all utilized as private residences. The Hodgson House is the only structure that is visible from the project site; however, it should be noted that this structure has been modified to accommodate the residential land use. The portion of the subject site near the Hodgson House is proposed as commercial land use; File 44928S 11 Greenway Engineering IMPACT ON COMMUNITY FACILITIES Fire and Rescue Parks and Recreation Silver Lake, LLC Rezoning therefore, the County Zoning Ordinance will require buffering and screening between the proposed land use and the existing residential land uses to mitigate visual impacts. The southwestern portion of the 2' Winchester Core Battlefield area (Phase 6) is located on adjacent properties that have been incorporated into the County's Sewer and Water Service Area (SWSA); therefore, it is anticipated that these adjoining properties will develop in the future. The identified core battlefield adjoins the portion of the 370.02+ acre site that is proposed as a CCRC. The development of a CCRC will require buffering and screening against the adjoining property due to the current agricultural land uses. The Master Development Plan for the CCRC will utilize the existing mature woodland areas to provide for buffering and screening; therefore, this will mitigate visual impacts to the southwestern portion of the core battlefield area on the adjoining properties. The development of commercial retail and office and a Continuing Care Retirement Community will create an impact to fire and rescue services in this area of the community. The Applicant has provided for this impact through a proffer that provides land to Frederick County for the development of a new fire and rescue station and support facilities serving the Round Hill Community. The Applicant's proffer calls for the dedication of land fronting on Silver Lake Road that is located near the intersection of Northwestern Pike (U.S. Route 50 west), which is a minimum of three acres and a maximum of four acres in size. Additionally, the Applicant has proffered to provide a monetary contribution to Frederick County in the amount of $1,000,000.00 for the development of a new fire and rescue station providing service to the Round Hill Community, to develop the necessary access and infrastructure to the new facility if it is located on the project site, and to design proffered traffic signalization with preemption technology. Should the new fire and rescue station providing service to the Round Hill Community be developed at another location, the Applicant has proffered to provide an additional $100,000.00 for the development of this facility. Therefore, the Applicant's proffer statement more than adequately addresses impacts to fire and rescue services. The Applicant proffered land to Frederick County to provide a 10 -acre site located along Northwestern Pike around an including the existing pond feature to provide for public recreational opportunities consistent with the Comprehensive Policy Plan. The Frederick County Parks and Recreation Board considered this request during their January 2009 meeting and decided not to accept this proffered site. The Applicant has incorporated a complete network of trail systems and sidewalks that will link all commercial and office land uses and the Continuing Care Retirement Community (CCRC) to create a walkable File #4928s 12 Greenway Engineering campus design for the subject properties. Additionally, the CCRC will be developed with a wellness center and other on -site services to meet the recreational needs of their community. Therefore, the development of this project will not have a negative impact to parks and recreation services. Educational Facilities The development of commercial retail and office and a Continuing Care Retirement Community will not impact public school facilities or operations. The County will receive revenues from the commercial and office development, which will assist in the annual budget necessary to fund public schools. General Government Silver Lake, LLC Rezoning The development of commercial retail and office and a Continuing Care Retirement Community will not impact general government facilities or operations. The County will receive revenues from the commercial and office development, which will assist in the annual budget necessary to fund general government services.

All other study area intersections during Phase 1 through Phase 3 will maintain levels of service "D" or better. During 2022 Phase 4 build -out conditions, all the study area intersections, except the intersection of Route 50/Route 37 northbound ramps, will operate with overall levels of service "D" or better. The aforementioned intersection of Route 50/Route 37 northbound ramps will! operate with levels of service "F" in PM peak hour conditions assuming the improvements. Based upon the Highway Capacity analysis results, assuming the suggested improvements, Route 50 will maintain link level of service "D" or better during all four (4) phases. The link levels of service shown in all lane geometry and levels of service figures represent the worst -case levels of service of two directions. The following describes the improvements suggested at each study area intersection during all four (4) phases Phase 1 (2012): Route 50 /Poorhouse Road: Signalization will be required. Route 50 /Spining Wheel Lane: This is a new intersection. Signalization, an eastbound left-turn lane, a westbound right -turn lane and a southbound left -turn lane will be required. Route 50 /Route 37 southbound ramps: A free -flow right -turn in southbound direction will be required. Phase 2 (2018): Route 50 /Poorhouse Road: Signalization will be required. Route 50 /Spining Wheel Lane: This is a new intersection. Signalization, an eastbound left -turn lane, a westbound right -turn lane and a southbound left -turn lane will be required. Route 50 /Silver Lake Road: This is a new intersection. Signalization will be required. Route 50 /Route 37 southbound ramps: A westbound through lane and a free -flow right -turn in southbound direction will be required. Route 50 /Route 37 northbound ramps: A westbound through lane and a northbound right -turn lane will be required. Additionally, a new connector road will be built to the north side of the site. The connector road will traverse parallel to Route 50 from Botanical Boulevard to Spinning Wheel Lane. There will be unsignalized intersections with Botanical Boulevard, Retail Boulevard, Silver Lake Road and Spinning Wheel Lane.

A Phased Traffic Impact Analysis of the Round Hill Center PH� Project Number: 15233-1-0 20 8 L 1 November 23 -1-0 Pau 61 Guiding Principles Round Hill Community Land Use Plan 2007 (Adopted by the Board of Supervisors on November 14, 2007) The Round Hill Community has two distinct areas, the long established Round Hill Rural Community Center focused around Round Hill Road (Route 803) and the developing commercial area along Route 50 (Northwestern Pike). This plan encompasses both of these areas. The plan has two primary goals first, to protect and enhance the character of the established rural community center and second, to create a vibrant, functional and well designed commercial center. While the two areas are distinct, this plan seeks to link them by efficient roads and multi purpose trails and sidewalks and to locate a park and other public facilities in the Round Hill Community for the benefit of both the residents and the workers. As with previous versions of the Round Hill Community Land Use Plan, a key goal of this plan is to provide public sewer and water access for the existing residents of the Round Hill community. Land Use Round Hill Rural Community Center The core of the long established Round Hill Rural Community Center consists primarily of residences. In the past, a number of small businesses have been located in the core area, but few of these remain today. The development pattern established in the Round Hill Rural Community Center consists of both small lots along Round Hill Road, Poorhouse Road, Woodchuck Lane and other roads, and the larger lots and small farms on the periphery. Both residential patterns should continue. The farms and large lots on the periphery of the Round Hill Rural Community Center should be maintained to preserve the rural character. In order to further preserve the existing character of the area, no part of the Round Hill Rural Community Center should have high density housing. Most residential lots in the Round Hill Rural Community Center are less than one -half acre. These residential lots contain single family detached housing on wells and septic with reduced front yard setbacks. This historic development pattern cannot be accommodated within the existing RA (Rural Areas) Zoning District, which allows one residence for every five acres and requires primary and reserve drainfield areas. A new zoning district should be created to accommodate infill development that is in character with the area. Such a district should address housing types, lot sizes and setbacks. The new zoning district should also address design standards for street trees, curb -side parking, signage, lighting and underground utilities. The new -1- zoning district could allow for modest conunercial/retail uses (with discreet signage) to serve sulTounding residents. In recent years, new residential development in Round Hill has been limited due to private health system requirements. Expansion of the Sewer and Water Service Area (SWSA) in 2006 has given the opportunity for some existing residents to connect to public water and sewer, at the property owner's expense. Once a new zoning district is adopted to accommodate in -fill development, the County will need to re- examine the SWSA boundary to determine whether any other areas in the Round Hill Rural Community Center should be enabled to connect to public water and sewer services. Rezonings to the new district should not be allowed prior to the availability of public water and sewer. Developing Commercial Areas Commercial, medical support, medical offices, educational, and public use development are important components of the Round I -Iill Community Land Use Plan. Historically, highway commercial uses have located along Route 50 (Northwestern Pike). These uses include gas stations, car dealers, restaurants and small retail establishments. Some of these uses still exist. In more recent years, Round Hill Crossing (including the large Wal -Mart center) has begun to develop on the north side of Route 50. This 70 acre site will ultimately accommodate retail, restaurant and business development. The Winchester Medical Center West Campus, with 102 acres to the east of Round Hill Crossing, has both a retail component along Route 50 and a medical component. The northern portion of the Medical Center's West Campus is zoned MS (Medical Support) District. Together these two large developments have changed the nature of land development along Route 50. Large -scale commercial development is now a dominating presence in the Round Hill Community. Growth and development should be carefully planned to take advantage of the close proximity of the Winchester Medical Center. Two distinct types of commercial development are evolving in the Round Hill Community— a general commercial area along both sides of Route 50 and a medical support and education area located on the north side of Route 50. The general commercial areas already under development on both sides of Route 50 function as a gateway to and from the City of Winchester. Therefore, an objective of this plan is to create an attractive, functional commercial area and to prevent the creation of a typical commercial strip. Consolidated entrances are strongly encouraged to avoid multiple entrances along Route 50. Inter parcel connections will be necessary for the small lots to develop. Standards have already been developed that will minimize the visual disruption to the Route 50 corridor (see Figure 13A). These include standards for shared entrances, inter parcel connectors, green spaces along Route 50, screening of parking areas, screening between commercial properties and existing residences, size, number and location of signs, underground utilities, and landscaping. These standards strongly discourage individual business entrances both for aesthetic reasons as well as for transportation safety and efficiency. Major commercial establishments should connect to Route 50 at signalized intersections. A continuation of the general commercial area is planned in the vicinity of Ward Avenue and Stonewall Drive. As this area redevelops, new developments will be expected to follow the Route 50 standards (Figure 13A) that apply to small parcels on the south side of Route 50. Consolidation of these small parcels is the key to redeveloping this area. A minor collector road, to join Round I -fill Road (Route 803) and Ward Avenue, is planned to funnel traffic to two key intersections on Route 50. Figure 13A Design Principles Encouraged for the Round Will Route 50 Corridor Street trees in the median, along both sides of the ditch; Freestanding business signs one monument style sign per development (Maximum size 50 feet, maximum height 12 feet); Crosswalks at signalized intersections, with signals for pedestrians; Intenparcel connectors required between all properties planned for commercial development (even if currently zoned RA and used for residential purposes) to encourage shared entrances; Commercial entrance spacing Commercial entrances are strongly discouraged on Route 50. If no other alternative exists, entrance spacing 200 feet if speed limit is 35 mph or less, 250 feet if speed limit is greater than 35 mph; A row of evergreens in addition to the ordinance- required buffer and screening adjacent to areas planned to remain residential; Underground utilities; Placement of buildings close to Route 50 with landscaped parking lots in the rear; North side of Route 50: 50 foot landscaped strip, within the landscaped strip a ten foot asphalt bike and pedestrian trail, ornamental shrubs and street trees along Route 50; South side of Route 50: 50 foot landscaped strip (20 feet for small tracts), within the landscaped strip a five foot concrete pedestrian sidewalk, ornamental shrubs and street trees along Route 50; Due to its close proximity to the Winchester Medical Center, the north side of Route 50 offers a unique opportunity to accommodate medical support, medical offices, educational, public use, and commercial uses. Therefore, the Round Hill Community Land Use Plan should provide for large campus style development of the north side of Route 50 for medical support, medical office, educational, public use, and commercial uses. A number of large open tracts of land exist in this location. The campus style development should provide for boulevard street designs, street trees, bicycle and pedestrian paths, and connectivity between development and common green space gathering areas. In order to minimize areas of impervious surface, decked or structured parking or increased building heights may be warranted. High quality building designs and materials are expected. Small plazas at the building entrances or in the center of a group of buildings are suggested. Site -3- design standards are expected to exceed those established for the Route 50 corridor (Figure 13A). Coordinated signage, lighting and street furniture are sought. All of the commercial areas in Round Hill should provide commercial services and employment opportunities that are accessible to the residents within the Round 1-lill Rural Community Center via alternative modes of transportation, such as pedestrian and bicycle facilities. Enhanced accessibility is anticipated through the connection of such areas to the existing residential areas by a network of multi- purpose trails, sidewalks and intersections with pedestrian actualized signals. Transportation The County's Eastern Road Plan and the Win -Fred Metropolitan Planning Organization (IMO) 2030 Transportation Plan call for Route 50 to be improved to a six -lane minor arterial road between Route 37 and Poorhouse Road (Route 654). West of Poorhouse Road, Route 50 is planned as a four -lane minor arterial. Sidewalks are planned on the south side of Route 50 and multi purpose trails on the north side. Developments along Route 50 will be expected to incorporate these road improvements. A north/south collector road, parallel to Route 37, is included in the Route 37 West Land Use Plan. This road is also incorporated into the County's Eastern Road Plan. A section of this road, Botanical Boulevard, is being built with the Winchester Medical Center West Campus development on the north side of Route 50. Should properties further to the north develop, this road should eventually connect to Route 522 (North Frederick Pike). An east/west collector road, parallel to Route 50 is also included in the Eastern Road Plan. A section of this road, Petticoat Gap Lane, has been proffered with the Round Hill Crossing development. This road is envisioned as an urban divided four -lane cross section that includes landscaped medians, controlled left turns, street trees, and pedestrian and bicycle facilities, to enhance transportation on the north side of Route 50. Development proposals will need to accommodate the continuation of this collector road. The location shown on the plan is general, with the precise location of the east -west collector road remaining flexible. A new north/south major collector road is planned through the Winchester Medical Center -West Campus that will serve the West Campus and provide access to the future Route 37 interchange located north of Round Hill. While this road is envisioned as an urban divided four -lane road that includes landscaped medians as well as pedestrian and bicycle facilities, it may initially be built as a two -lane road because development to the north may not occur for many years, if at all. The location shown on the plan is general, with the precise location of the north -south collector road remaining flexible. Vehicular management access is recommended throughout the Round Hill Rural Community Center, particularly along Route 50. A six lane arterial road should not include multiple access points. Ideally, primary vehicular access should be limited to four signalized intersections along Route 50 with additional commercial entrances planned at appropriate intervals to facilitate safe and efficient traffic movement. Noted throughout this plan is the requirement for alternative modes of transportation, such as pedestrian and bicycle facilities. The plan calls for an interconnected system of multi- purpose trails and sidewalks. It is critical that these alternative modes of transportation link the entire Round Hill Rural Community Center A future Winchester Medical Center internal road over Route 37 should provide a sidewalk and trail for bicycle and pedestrian access. The County should also encourage the extension of existing bus routes to serve the area. Ideally, bus stops should be located at all of the commercial centers. The development of new road systems, new signalization and improvements to existing road systems are all elements of this plan. It will be the responsibility of private property owners and developers to ensure that these improvements are made. No rezonings should be approved until the County is certain that the transportation impacts of development will be mitigated and the improvements facilitate the goals of the Comprehensive Policy Plan. As with all areas of the County, Level of Service "C" should be maintained on roads adjacent to and within new developments. Environment A number of environmental features are found in the Round Hill Community. The area is dominated by two major natural features Round Hill itself, which is west of Poorhouse Road and a north/south ridgeline. The ridgeline, west of Round Hill Crossing, is highly visible and should be sensitively developed. Ponds, streams and floodplains are present and will need to be taken into consideration so as to minimize and /or mitigate negative impacts with any future development. These natural areas provide an obvious location for a trail system. Historical Resources Round Hill is one of the older settlements in Frederick County. The original village was located at the base of Round Hill. The community today includes a small number of eighteenth and nineteenth century dwellings. Approximately 30 late nineteenth century and early -to -mid twentieth century houses, primarily American Foursquares and I- houses are located in the area. The mid- nineteenth century Round Hill Presbyterian Church and the early- twentieth century Round Hill School (now used as a residence) are also located in this community. Protection of these historic structures is encouraged. Public Utilities A fundamental issue for the development of Round Hill has been the provision of public water and sewer. Development of the area is dependent on the availability of appropriate infrastructure. The Sewer and Water Service Area (SWSA) has been expanded to portions of the Round Hill Rural Community Center several times in recent years. This plan does not recommend rezoning land within the Round Hill Rural Community Center for commercial development prior to the availability of central sewer and water. It is also recommended that as land is developed over time and infrastructure extended, that new developments further the goal of providing sewer and water to the core residential area of the Round Hill Rural Community. Future development should facilitate the availability of sewer and water in two ways —the sizing of utility pipes to insure capacity for all of the Round Hill Rural Community Center, and providing utility easements so that adjacent property owners have the ability to extend and connect to public water and sewer. The Round Hill area will ultimately be served by two wastewater treatment plants. The area immediately west of Route 37, including Winchester Medical Center West Campus and Round Hill Crossing are currently served by the Opequon Water Reclamation Facility. The transmission lines serving this facility have limited capacity. Therefore, future development south of Route 50 and also west of Round I -Iill Crossing are planned to be served by the Parkins Mill Wastewater Treatment Plant. An expansion of the Parkins Mill Plant has been designed and the expanded plant should be operational in 2009. Adequate wastewater capacity to serve the Round Hill Rural Community Center should be available by 2010. Future development proposals will need to demonstrate that sufficient sewer capacity exists. Water lines exist on Route 50 in the area of Round Hill Crossing and the Winchester Medical Center West Campus. These water lines have sufficient capacity to provide the volume of water identified in the Round Hill Community Land Use Plan; however, they do not have sufficient pressure. To provide adequate pressure, existing line pressure will have to be boosted and water storage provided. Public Facilities 0 Public facilities to serve new development in the Round Hill Community may be required in the future. It will be necessary for future development to provide a site for such public facilities. The Round Hill Volunteer Fire Rescue Company, in particular, is in need of a site for a new facility. Parks The Round Hill Community has one neighborhood park, at the Round Hill Volunteer Fire Rescue Station. A children's play area is maintained by the Frederick County Department of Parks and Recreation and the fire company maintains a ball field. The scope of this park could be expanded, possibly with the relocation of the fire station. The commercial, medical support, and institutional land uses north of Route 50 should include a new park, ideally in the area of the large pond. This park would be visible from Route 50 and could serve as the visual focal point of the entire Round Hill Community. The park should be a passive recreational facility with trails, benches and outdoor eating areas. The park should be designed to serve both onsite workers and residents of the Round Hill Rural Community Center. A linear trail could also link this park to the smaller pond to the north. The Pm trail /sidewalk network should be the interconnected trail system as described in the transportation section. Consideration should be given to establishing a trail along the ridgeline between Route 50 and Route 522 and a trail at the southern edge of the Round Hill Community to link to the Green Circle in the City of Winchester. -6 On October 12, 2005, the Frederick County Board of Supervisors directed staff to use the Development Impact Model (DIM) to project the capital fiscal impacts that would be associated with any rezoning petitions containing residential development, replacing the existing Capital Facilities Fiscal Impact Model. The DIM was created by an economic consultant who evaluated and analyzed development within the County in an effort to assist the County in planning for future capital facility requirements. Critical inputs to the DIM are to be reviewed and updated annually to assure that the fiscal projections accurately reflect County capital expenditures. The Board of Supervisors authorized use of the annual model update on June 25, 2008. The DIM projects that, on average, residential development has a negative fiscal impacts on the County's capital expenditures. As such, all rezoning petitions with a residential component submitted after June 25, 2008 will be expected to demonstrate how the proposal will mitigate the following projected capital facility impacts: 06/25/08 Single Family Dwelling Unit Town Home Dwelling Unit Apartment Dwelling Unit Development Impact Model $23,818 $16,965 S 8,975 The following is a breakdown of the projected impacts per dwelling unit for each capital facility.

Build -out is anticipated to occur over four (4) transportation phases by the Year 2022. Phase 1 will be built -out by Year 2012 and it assumes partial build -out of the development to include: 122 elderly detached units, 448 elderly attached units and 180,000 square feet of shopping center. Access to the site will be provided via Spinning Wheel Lane located along the north side of Route 50. Phase 2 will be built -out by Year 2018 and it assumes partial build -out of the development to include: 122 elderly detached units, 448 elderly attached units, 105,000 square feet of office and 350,000 square feet of shopping center. Access will be provided via Spinning Wheel Lane, Proposed Silver Lake Road, Retail Boulevard, and Botanical Boulevard located along the north side of Route 50. Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard will be connected via the Proposed Connector Road. Phase 3 will be built -out by Year 2020 and it assumes partial build -out of the development to include: 122 elderly detached units, 448 elderly attached units, 350,000 square feet of office and 490,000 square feet of shopping center. Phase 4 will be build -out by Year 2022 and it assumes the full build -out of the proposed Round Hill Center development. For Phase 3 and Phase 4, access will be provided via Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard located along the north side of Route 50. Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard will be connected via the Proposed Connector Road. Additionally, access will provided via Poorhouse Road, which will be connected to the Relocated Spinning Wheel Lane. As a result of this connection, it is assumed that 20% of the traffic coming from the north on Route 37 and going to west on Route 50, during Phase 3 and Phase 4 background conditions, will be re- routed to be coming from the north on Poorhouse Road and going to the west on Route 50. Figure 1 is provided to illustrate the location of the proposed Round Hill Center development with respect to the surrounding roadway network. A Phased Traffic Impact Analysis of the Round [fill Center Project Number: 15233 -1 -0 November 25, 2008 Page 1 Methodology The traffic impacts accompanying the Round Hill Center 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 Round Hill Center development, o Distribution and assignment of the Round Hill Center development- generated trips onto the completed roadway network, Analysis of capacity and level of service using the latest version of Synchro for existing and future conditions.

Access will be provided via Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard located along the north side of Route 50. Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard will be connected via the Proposed Connector Road. PHASE 2 2018 BACKGROUND CONDITIONS In order to determine the 2018 background traffic conditions, PHR +A grew the existing traffic volumes (shown in Figure 2) using a rate of 2.0% per year through Year 2018. Additionally, all trips relating to specific future "other developments" located within the vicinity of the site were incorporated. Using the 7 Edition of the Institute of Transportation Engineers' (ITE) Trip Generation Report, PHR +A has provided Tables 2a through 2d in Phase 1 analysis on pages 9 -10 to summarize the 2018 "other developments" trip generation. Figure 10 shows the 2018 background 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 11 shows the corresponding 2018 build -out lane geometry and AM/PM peak hour and Saturday mid -day peak hour levels of service.

Table 7 is provided to summarize the total trip generation associated with the Phase 2 of Round Hill Center development. Average rams are utilized. Table 7 Proposed Development: Round Hill Center Phase 2 Trio Generation Summary PHASE 2 TRIP DISTRIBUTION AND TRIP ASSIGNMENT The distribution of trips was based upon local travel patterns for the roadway network surrounding the proposed site. PHR +A utilized the trip distribution percentages shown in Figure 12 to assign the Round Hill Center Phase 2 development trips (Table 7) throughout the study area roadway network. Figure 13 shows the development generated 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. The Round Hill Center Phase 2 assigned trips (Figure 13) were added to the 2018 background traffic volumes (Figure 10) to obtain 2018 build -out conditions. Figure 14 shows the 2018 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 within the study area.

Access will be provided via Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard located along the north side of Route 50. Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard will be connected via the Proposed Connector Road. Additionally, access will provided via Poorhouse Road, which will be connected to the Relocated Spinning Wheel Lane. As a result of this connection, it is assumed that 20% of the traffic coming from the north on Route 37 and going to west on Route 50 will be re- routed to be coming from north on Poorhouse Road and going to west on Route 50. PHASE 3 2020 BACKGROUND CONDITIONS In order to determine the 2020 background traffic conditions, PHR +A grew the existing traffic volumes (shown in Figure 2) using a rate of 2.0% per year through Year 2020. Additionally, all trips relating to specific future "other developments" located within the vicinity of the site were incorporated. Using the 7 Edition of the Institute of Transportation Engineers' (ITE) Trip Generation Report, PHR +A has provided Tables 2a through 2d in Phase 1 analysis of this report (pages 9 -10) to summarize the 2020 "other developments" trip generation. Figure 16 shows the 2020 background 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 17 shows the corresponding 2020 build -out lane geometry and weekday AM/PM peak hour and Saturday mid -day peak hour levels of service. All Synchro and HCS+ levels of service worksheets are provided in the Appendix section of this report.

Access will be provided via Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard located along the north side of Route 50. Spinning Wheel Lane, Silver Lake Road, Retail Boulevard, and Botanical Boulevard will be connected via the Proposed Connector Road. Additionally, access will provided via Poorhouse Road, which will be connected to the Relocated Spinning Wheel Lane. As a result of this connection, it is assumed that 20% of the traffic coming from the north on Route 37 and going to west on Route 50, during Phase 3 and Phase 4 background conditions, will be re- routed to be coming from the north on Poorhouse Road and going to the west on Route 50. In order to determine the 2022 background traffic conditions, PHR +A grew the existing traffic volumes (shown in Figure 2) using a rate of 2.0% per year through Year 2022. Additionally, all trips relating to specific future "other developments" located within the vicinity of the site were incorporated. Using the 7 Edition of the Institute of Transportation Engineers' (ITE) Trip Generation Report, PHR +A has provided Tables 12a through 12d to summarize the 2022 "other developments" trip generation.

Table 14 is provided to summarize the total trip generation associated with the Phase 4 of Round Hill Center development. Averag auto are utilized. PHASE 4 TRIP DISTRIBUTION AND TRIP ASSIGNMENT The distribution of trips was based upon local travel patterns for the roadway network surrounding the proposed site. PHR +A utilized the trip distribution percentages shown in Figure 24 to assign the Round Hill Center Phase 4 development trips (Table 14) throughout the study area roadway network. Figure 25 shows the development- generated 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. PHASE 4 2022 BUILD -OUT CONDITIONS The Round Hill Center Phase 4 assigned trips (Figure 25) were added to the 2022 background traffic volumes (Figure 22) to obtain 2022 build -out conditions. Figure 26 shows the 2022 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. Figure 27 shows the respective 2022 build -out lane geometry and weekday AM /PM peak hour and Saturday mid -day peak hour levels of service. All Synchro and HCS+ levels of service worksheets are included in the Appendix section of this report.

All other study area intersections during Phase 1 through Phase 3 will maintain levels of service "D" or better. During 2022 Phase 4 build -out conditions, all the study area intersections, except the intersection of Route 50 /Route 37 northbound ramps, will operate with overall levels of service "D" or better. The aforementioned intersection of Route 50 /Route 37 northbound ramps will operate with levels of service "F" in PM peak hour conditions assuming the improvements. Based upon the Highway Capacity analysis results, assuming the suggested improvements, Route 50 will maintain link level of service "D" or better during all four (4) phases. The link levels of service shown in all lane geometry and levels of service figures represent the worst -case levels of service of two directions. The following describes the improvements suggested at each study area intersection during all four (4) phases: Phase 1 (2012): Route 50 /Poorhouse Road: Signalization will be required. Route 50 /Spining Wheel Lane: This is a new intersection. Signalization, an eastbound left -turn lane, a westbound right -turn lane and a southbound left-turn lane will be required. Route 50 /Route 37 southbound ramps: A free -flow right -turn in southbound direction will be required. 9 Phase 2 (2018): Route 50 /Poorhouse Road: Signalization will be required. Route 50 /Spining Wheel Lane: This is a new intersection. Signalization, an eastbound left -turn lane, a westbound right -turn lane and a southbound left -turn lane will be required. Route 50 /Silver Lake Road: This is a new intersection. Signalization will be required. Route 50 /Route 37 southbound ramps: A westbound through lane and a free -flow right-turn in southbound direction will be required. Route 50 /Route 37 northbound ramps: A westbound through lane and a northbound right -turn lane will be required. Additionally, a new connector road will be built to the north side of the site. The connector road will traverse parallel to Route 50 from Botanical Boulevard to Spinning Wheel Lane. There will be unsignalized intersections with Botanical Boulevard, Retail Boulevard, Silver Lake Road and Spinning Wheel Lane.

Route 50 /Botanical Boulevard: An eastbound through lane and pavement re- striping in northbound and southbound directions will be required. Route 50 /Route 37 southbound ramps: An eastbound and a westbound through lane as well as a free -flow right -turn in southbound direction will be required. Route 50 /Route 37 northbound ramps: An eastbound, westbound through lane, a northbound right -turn lane as well as other regional improvements will be required. ane: This is a new intersection. Signalization, an Additionally, a new connector road will be built to the north side of the site. The connector road will traverse parallel to Route 50 from Botanical Boulevard to Poorhouse Road. There will be unsignalized intersections with Botanical Boulevard, Retail Boulevard, Silver Lake Road, Spinning Wheel Lane and Poorhouse Road.
