Box 2097 Winchester, VA 22604 GREENWAY ENGINEERING, INC. 151 Windy Hill Lane Winchester, VA 22602 Telephone 540-662-4185 Founded in 1971 Fax 540-722-4185 Engineers Surveyors www. ear enwayen .com FN# 2160E Executive Summary ' A multi -unit residential apartment building is proposed on a six -acre property adjacent to Route 659 and located within the floodplain for Abrams Creek. The property is located in Frederick County, Virginia and is identified as 55-((A))-181C on the Frederick County ' Tax Map. A hydraulic analysis was performed with the objectives of determining the existing base flood elevation (BFE) for the 100-year event on the undeveloped site, and determining whether a proposed residential structure, placed on fill, would be above that BFE. The analysis also considered the effect of the fill on the BFE to ensure that the flood elevation ' would not increase by more than one foot. The U.S. Army Corps of Engineers HEC-River Analysis System (HEC-RAS) was used for performing the hydraulic analysis. The hydrologic data was obtained from a flood ' plain easement delineation performed on the upstream adjacent property by -Painter - Lewis, P.L.C. and dated June 10, 1999. ' The results of the hydraulic analysis show that the proposed structure can be raised by fill to an elevation above the BFE and that fill does not raise the BFE by more than one foot. Introduction ' The subject property is located in Frederick County, Virginia and is identified as parcel #55-((A))-181C on the Frederick County Tax Map (Exhibit 1). The six -acre parcel is adjacent to Abrams Creek and the southern limit of the property is within the banks of the creek. The northern limit of the property is Rt. 659 — Valley Mill Road. Residential lots border the property on the west and the parcel to the east is undeveloped. The property ' appears on the FEMA National Flood Insurance Program (NFIP) Flood Insurance Rate Map (FIRM) 510063-0120B, and much of the property is shown with a Zone A designation (Exhibit 2). The property owner wishes to construct a multi -unit apartment building on the property and wishes to elevate the building with fill so that it is above the Base Flood Elevation for the 100-year event. ' Objective The purpose of this study is as follows: 1. Determine the existing BFE for the 100-year event on the undeveloped site. 2. Consider the effect of the proposed fill on the BFE to ensure that the flood elevation would not increase by more than one foot. ' 3. Determine whether the proposed structure would be above the proposed BFE based on fill. Upstream Analysis - Longerbeam Property A floodplain easement delineation was previous completed on a portion of Abrams Creek for the adjacent upstream property in June 1999 to determine the 100-year floodplain limits for the development of proposed single-family residential lots. The analysis is titled, "Longerbeam Property — Route 659, Abrams Creek — Frederick County, Flood Plain Easement Delineation and was performed by Painter -Lewis, P.L.C. of ' Winchester, Virginia. The summary report and hydrologic modeling information used in the Longerbeam analysis was made available to Greenway Engineering and the flow data was used in the current analysis. The property has since been developed, so the hydraulic data from the Longerbeam analysis was not used for the current study. The 16.81 square mile watershed is composed of "a mixture of agricultural areas, residential areas, industrial/ commercial development, and the City of Winchester", according to the Longerbeam analysis, and TR-20 was used to develop a peak flow rate for the 100-year storm event at the point of analysis. The peak flow rate for the 100-year event was determined to be 8978.7 cfs according to the Longerbeam analysis, so a rate of t8980 cfs was used in the current analysis. The TR-20 calculations used in developing the peak flow rate are included in Appendix A. ii 1 On -Site Hydraulic Analysis (Stations 10+00.00 to 20+16.19) 11 F HEC-RAS was used to calculate the water surface elevation based on the Longerbeam flow data and cross section data from a topographical survey performed by Greenway Engineering on April 28, 2006. The reach stationing and cross section alignment are shown in Exhibits 3 and 4. Cross sections were taken at approximate 100-foot intervals, with station 10+00 just beyond the eastern boundary and station 20+16.19 located 262 feet upstream of the western boundary. The cross sections were then modified to show the proposed fill and structure to be placed on the property. HEC-RAS was run again to calculate a post -developed water surface elevation. Full HEC-RAS calculations are given in Appendix B, and the summary is given below. Table 1 - HEGRAS Summary River Station Plan Q Total (cfs) W.S. Elev. (ft.) A W.S. Elev.

Also, the greatest increase in flood elevation from pre -developed conditions to post -developed conditions is 0.28 feet at station 18+80.90. The highest proposed water surface elevation on -site is 571.37 and the proposed structure's lowest ' floor elevation is 574.70. The proposed structure's lowest adjacent grade (LAG) is also higher than the base flood elevation at all cross sections. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Exhibits Exhibit 1 Frederick County Tax Map Exhibit 2 NFP FIRM Panel Exhibit 3 Existing Floodplain Geometry Exhibit 4 Proposed Floodplain Geometry AA�i �f�f_e i�����L �i�i'.:iCtt?' ����o .O�w_ �����i►.�u QI. ��r��AI�_ (r �wo00��1 664 o. o/ a ZONE C �. _ .

Box 2097 Winchester, VA 22604 GREENWAY ENGINEERING, INC. 151 Windy Hill Lane Winchester, VA 22602 Telephone 540-662-4185 Fax 540-722-4185 www.ereenwUeng.com Executive Summary A multi -unit residential apartment building is proposed on a six -acre property adjacent to Route 659 and located within the floodplain for Abrams Creek. The property is located in Frederick County, Virginia and is identified as 55-((A))- 18 1 C on the Frederick County Tax Map. A hydraulic analysis was performed with the objectives of determining the existing base Y Y P J g g flood elevation (BFE) for the 100-year event on the undeveloped site, and determining whether a proposed residential structure, placed on fill, would be above that BFE. The analysis also considered the effect of the fill on the BFE to ensure that the flood elevation would not increase by more than one foot. The U.S. Army Corps of Engineers HEC-River Analysis System (HEC-RAS) was used for performing the hydraulic analysis. The hydrologic data was obtained from a flood plain easement delineation performed on the upstream adjacent property by Painter - Lewis, P.L.C. and dated June 10, 1999. The results of the hydraulic analysis show that the proposed structure can be raised by fill to an elevation above the BFE and that fill does not raise the BFE by more than one foot. 1 Introduction The subject property is located in Frederick County, Virginia and is identified as parcel #55-((A))-181C on the Frederick County Tax Map (Exhibit 1). The six -acre parcel is adjacent to Abrams Creek and the southern limit of the property is within the banks of the creek. The northern limit of the property is Rt. 659 — Valley Mill Road. Residential lots border the property on the west and the parcel to the east is undeveloped. The property appears on the FEMA National Flood Insurance Program (NFIP) Flood Insurance Rate Map (FIRM) 510063-0120B, and much of the property is shown with a Zone A designation (Exhibit 2). The property owner wishes to construct a multi -unit apartment building on the property and wishes to elevate the building with fill so that it is above the Base Flood Elevation for the 100-year event. Objective The purpose of this study is as follows: 1. Determine the existing BFE for the 100-year event on the undeveloped site. 2. Consider the effect of the proposed fill on the BFE to ensure that the flood elevation would not increase by more than one foot. 3. Determine whether the proposed structure would be above the proposed BFE based on fill. Upstream Analysis - Longerbeam Property A floodplain easement delineation was previous completed on a portion of Abrams Creek for the adjacent upstream property in June 1999 to determine the 100-year floodplain limits for the development of proposed single-family residential lots. The analysis is titled, "Longerbeam Property — Route 659, Abrams Creek — Frederick County, Flood Plain Easement Delineation", and was performed by Painter -Lewis, P.L.C. of Winchester, Virginia. The summary report and hydrologic modeling information used in the Longerbeam analysis was made available to Greenway Engineering and the flow data was used in the current analysis. The property has since been developed, so the hydraulic data from the Longerbeam analysis was not used for the current study. The 16.81 square mile watershed is composed of "a mixture of agricultural areas, residential areas, industrial/ commercial development, and the City of Winchester", according to the Longerbeam analysis, and TR-20 was used to develop a peak flow rate for the 100-year storm event at the point of analysis. The peak flow rate for the 100-year event was determined to be 8978.7 cfs according to the Longerbeam analysis, so a rate of 8980 cfs was used in the current analysis. The TR-20 calculations used in developing the peak flow rate are included in Appendix A. 1 1 1 1 1 1 1 1 1 1 I 1 1 1 1 I 1 1 1 On -Site Hydraulic Analysis (Stations 10+00.00 to 20+16.19) HEC-RAS was used to calculate the water surface elevation based on the Longerbeam flow data and cross section data from a topographical survey performed by Greenway Engineering on April 28, 2006. The reach stationing and cross section alignment are shown in Exhibits 3 and 4. Cross sections were taken at approximate 100-foot intervals, with station 10+00 just beyond the eastern boundary and station 20+16.19 located 262 feet upstream of the western boundary. The cross sections were then modified to show the proposed fill and structure to be placed on the property. HEC-RAS was run again to calculate a post -developed water surface elevation. Full HEC-RAS calculations are given in Appendix B, and the summary is given below. Table 1- HEC-RAS Summary River Station Plan Q Total (cfs) W.S. Elev. (ft.) A W.S. Elev.

Also, the greatest increase in flood elevation from pre -developed conditions to post -developed conditions is 0.28 feet at station 18+80.90. The highest proposed water surface elevation on -site is 571.37 and the proposed structure's lowest floor elevation is 574.70. The proposed structure's lowest adjacent grade (LAG) is also higher than the base flood elevation at all cross sections.

This master development plan is approved for the potential development of 5.58 acres of land in the RP (Residential Performance) District within the Redbud Magisterial District. This site is approved for the development of two garden apartment buildings; one building would consist of 13 units and the second would consist of 12 units (density of 4.48 units per acre). The property which would comprise this development is located on the south side of Valley Mill Road (Route 659), approximately 1,200 feet east of Channing Drive and 0.5 miles west of Greenwood Road. The Frederick County Board of Supervisors granted staff administrative approval authority on October 14, 2009. All requirements of the Frederick County Zoning and Subdivision Ordinance have been addressed in the plan. Please note that approval of a site plan is required prior to the subdivision or development of this parcel. I am providing you with six (6) copies of the approved final master development plan. Please ensure that these plans are distributed accordingly. Feel free to contact me if you have any questions. Sincerely, Candice E.

LOCATION: The subject property is located on the south side of Valley Mill Road (Route 659), approximately 1,200 feet east of Channing Drive and 0.5 miles west of Greenwood Road. STAFF CONCLUSIONS FOR THE 10/14/09 BOARD OF SUPERVISORS MEETING: The Master Development Plan for the Fieldstone Apartments property depicts appropriate land uses and appears to be consistent with the requirements of Article VIII, Master Development Plan, of the Zoning Ordinance, and this MDP is in a form that is administratively approvable. All of the issues brought forth by the Board of Supervisors should be appropriately addressed by the applicant. It appears that the application meets all requirement& Following presentation of the application to the Planning Commission and the Board of Supervisors, and the incorporation of your comments, staff is prepared to proceed to approval of the application. MDP #02-09, Fieldstone Apartments September 30, 2009 Page 2 This report is prepared by the Frederick County Planning Staff to provide information to the Planning Commission and the Board of Supervisors to assist in the review of this application. It may also be useful to others interested in this zoning matter. LOCATION: The subject property is located on the south side of Valley Mill Road (Route 659), approximately 1,200 feet east of Channing Drive and 0.5 miles west of Greenwood Road. MAGISTERIAL DISTRICT: Red Bud PROPERTY ID NUMBER: 55-A-181C PROPERTY ZONING & PRESENT USE: Zoned: RP (Residential Performance) District Use: Vacant ZONING & PRESENT USE OF ADJOINING PROPERTIES: North: RP (Residential Performance RA (Rural Areas) South: RP (Residential Performance East: RP (Residential Performance West: RP (Residential Performance Use: Residential Use: Carlisle Heights Open Space Use: Vacant Use: Residential and Open Space PROPOSAL: To develop 5.58 acres of land zoned RP (Residential Performance) with two garden apartment buildings, one building would consist of 13 units and the second would consist of 12 units (density of 4.48 units per acre). REVIEW EVALUATIONS: Virginia Department of Transportation: The Master Development Plan for this property appears to have a measurable impact on Route 659, the VDOT facility which would provide access to the property. The proposed Master Development Plan appears acceptable to VDOT. Before making any final comments, this office will require a complete set of site plans, drainage calculations and traffic flow data from the I.T.E. Trip Generation Manual, Seventh Edition for review. VDOT reserves the right to comment on all right-of-way needs, including right-of-way dedications, traffic signalization and off -site MDP #02-09, Fieldstone Apa«ments September 30, 2009 Page 3 roadway improvements and drainage. Prior to construction on the State's right-of-way, the developer will need to apply to this office for issuance of appropriate permits to cover said work. Frederick County Fire Marshal: Plan approval recommended. Frederick County Public Works: We have completed our review of the revised master development plan dated February 24, 2009. All of our previous comments have been addressed; therefore, we recommend approval of the subject master development plan. Frederick County Inspections Department: No comments at this time. Comments made at site plan submittal. Frederick County Sanitation Authority: There is adequate sewer and water capacity to serve this development. GIS Department: No additional road names are required at this time. The addresses for the structures will be: Building Area (13 apartments): 860 Valley Mill Rd Apartments 1-13, and Building Area (12 apartments): 870 Valley Mill Rd Apartments 1-12. Parks and Recreation Department: The plan appears to meet the open space and recreational unit ordinance requirements. The developer is also providing a 20' easement for a bike/pedestrian trail along Abrams Creek. In addition, staff is recommending, as outlined in the M.P.O. Bike Pedestrian Plan, a 10' paved bike/pedestrian trail along Valley Mill Road. (The revised MDP dated 812112009 has addressed the comment regarding the trail). Winchester Regional Airport: We have reviewed the proposed Master Development Plan for Fieldstone Apartments and it appears that this plan should not impact operations at the Winchester Regional Airport. However, this proposed site does lie within airspace of the Winchester Regional Airport and residents in that area may experience noise from over flights of aircraft operating in and out of the Winchester Regional Airport. Potential homeowners/tenants should be forewarned about the proximity of this site to the Winchester Airport. Frederick County Schools: Thank you for providing the requested acceleration lane east of the proposed entrance for a bus stop, a sidewalk to the bus stop and accompanying street signage. The acceleration lane will provide some refuge outside of the Valley Mill Road travelway for eastbound buses. Please be aware that we will not be able to send buses onto this property, as there will be no bus turnaround in the parking lot. Frederick County Public Schools is concerned about all land development applications. Both capital expenditures and annual operating costs are increased by each approved residential development. Planning & Zoning: A) Master Development Plan Requirement A master development plan is required prior to development of this property. Before a master development plan can be approved, it must be reviewed by the Planning Commission, Board of Supervisors and all relevant review agencies. Approval may only be granted if the master MMP #02-09, Fieldstone Apa,,ments September 30, 2009 Page 4 development plan conforms to all requirements of the Frederick County Zoning and Subdivision Ordinances. The purpose of the master development plan is to promote orderly and planned development of property within Frederick County that suits the characteristics of the land, is harmonious with adjoining property and is in the best interest of the general public. B) Location The subject property is located on the south side of Valley Mill Road (Route 659), 0.5 miles east of Greenwood Road. C) Site History The original Frederick County Zoning Map (U.S.G.S. Stephenson Quadrangle) identified the zoning for the acreage within the master development plan as A-2 (Agricultural General) District. On September 9, 1987 the Board of Supervisors approved Rezoning #23-87 which rezoned the site from the A-2 District to the RP (Residential Performance) District. The 5.58 acre site was originally part of a 108 acre parcel; the remainder of the site is part of the Arcadia development. D) Site Suitability & Proiect Scope Comprehensive Policy Plan: The Frederick County Comprehensive Policy Plan is an official public document that serves as the community's guide for making decisions regarding development, preservation, public facilities and other key components of community life. The primary goal of this plan is to protect and improve the living environment within Frederick County. It is in essence a composition of policies used to plan for the future physical development of Frederick County. [Comprehensive Policy Plan, p. 1-1] Land Use Compatibility: The parcel comprising this MDP application is located within the County's Urban Development Area (UDA) and Sewer and Water Service Area (SWSA). The Urban Development Area defines the general area in which more intensive forms of residential development will occur. In addition, the Eastern Frederick County Long Range Land Use map designates the general area in which the Fieldstone Apartments development is located for residential land uses. The Fieldstone Apartments project will develop with a density of 4.48 units per acre. Site Access and Transportation: This proposed development will be accessed via one entrance on Valley Mill Road with a right turn lane and an acceleration lane. The development will also be constructing a ten foot paved trail along a portion of the Valley Mill Road frontage and then transitioning to a trail along the creek. The Eastern Road Plan of the Comprehensive Policy Plan shows Valley Mill Road as an improved major collector road (UD4). While this development will not be constructing roads other than a turn land and an acceleration lane, they have demonstrated that there is sufficient right-of-way available on the southern side of Valley Mill Road for future improvements. MDP #02-09, Fieldstone Apa. �ments September 30, 2009 Page 5 Buffers and Screening: A reduced 50 foot road efficiency buffer will be provided along a portion of Valley Mill Road; this buffer will consist of six foot berm and a single row of evergreen trees. The remainder of the Valley Mill Road frontage will have an 80 foot full road efficiency buffer; this buffer will consist of a double row of evergreen trees. A 100 foot full screen residential buffer is being provided along the residential property to the west; this buffer will consist of a six foot opaque fence and three trees per ten linear feet (1 /3 evergreen trees, 1 /3 deciduous trees, 1 /3 shrubs). Environmental Features. - The Fieldstone Apartments property does contain various environmental features, including floodplain and steep slopes. Abrams Creek runs through the rear of this property and the limits of the 100 year floodplain are shown on the MDP. This property has received a Conditional Letter of Map Revision from FEMA for the proposed floodplain modifications. The site also has small areas of steep slopes as indicated on sheet 3. STAFF CONCLUSIONS FOR THE 09/16/09 PLANNING COMMISSION MEETING: The Master Development Plan for the Fieldstone Apartments property depicts appropriate land uses and appears to be consistent with the requirements of Article VIII, Master Development Plan, of the Zoning Ordinance, and this MDP is in a form that is administratively approvable.

Perkins, AICP, Senior Planner Reviewed Action Planning Commission: 09/16/09 Pending Board of Supervisors: 10/14/09 Pending PROPOSAL: To develop 5.58 acres of land zoned RP (Residential Performance) with two garden apartment buildings; one building would consist of 13 units and the second would consist of 12 units (density of 4.48 units per acre). LOCATION: The subject property is located on the south side of Valley Mill Road (Route 659), approximately 1,200 feet east of Channing Drive and 0.5 miles west of Greenwood Road. STAFF CONCLUSIONS FOR THE 09/16/09 PLANNING COMMISSION MEETING: The Master Development Plan for the Fieldstone Apartments property depicts appropriate land uses and appears to be consistent with the requirements of Article VIII, Master Development Plan, of the Zoning Ordinance, and this MDP is in a form that is administratively approvable. All of the issues brought forth by the Planning Commission should be appropriately addressed prior to a recommendation to the Board of Supervisors. It appears that the application meets all requirements. Following presentation of the application to the Planning Commission and the Board of Supervisors, and the incorporation of your comments, staff is prepared to proceed to approval of the application. MDP #02-09, Fieldstone Apartments September 1, 2009 Page 2 This report is prepared by the Frederick County Planning Staff to provide information to the Planning Commission and the Board of Supervisors to assist in the review of this application. It may also be useful to others interested in this zoning matter. LOCATION: The subject property is located on the south side of Valley Mill Road (Route 659), approximately 1,200 feet east of Charming Drive and 0.5 miles west of Greenwood Road. MAGISTERIAL DISTRICT: Red Bud PROPERTY ID NUMBER: 55-A-181C PROPERTY ZONING & PRESENT USE: Zoned: RP (Residential Performance) District Use: Vacant ZONING & PRESENT USE OF ADJOINING PROPERTIES: North: RP (Residential Performance RA (Rural Areas) South: RP (Residential Performance East: RP (Residential Performance West: RP (Residential Performance Use: Residential Use: Carlisle Heights Open Space Use: Vacant Use: Residential and Open Space PROPOSAL: To develop 5.58 acres of land zoned RP (Residential Performance) with two garden apartment buildings, one building would consist of 13 units and the second would consist of 12 units (density of 4.48 units per acre). REVIEW EVALUATIONS: Virginia Department of Transportation: The Master Development Plan for this property appears to have a measurable impact on Route 659, the VDOT facility which would provide access to the property. The proposed Master Development Plan appears acceptable to VDOT. Before making any final comments, this office will require a complete set of site plans, drainage calculations and traffic flow data from the I.T.E. Trip Generation Manual, Seventh Edition for review. VDOT reserves the right to comment on all right-of-way needs, including right-of-way dedications, traffic signalization and off -site MDP #02-09, Fieldstone Apartments September 1, 2009 Page 3 roadway improvements and drainage. Prior to construction on the State's right-of-way, the developer will need to apply to this office for issuance of appropriate permits to cover said work. Frederick County Fire Marshal: Plan approval recommended. Frederick County Public Works: We have completed our review of the revised master development plan dated February 24, 2009. All of our previous comments have been addressed; therefore, we recommend approval of the subject master development plan. Frederick County Inspections Department: No comments at this time. Comments made at site plan submittal. Frederick County Sanitation Authority: There is adequate sewer and water capacity to serve this development. GIS Department: No additional road names are required at this time. The addresses for the structures will be: Building Area (13 apartments): 860 Valley Mill Rd Apartments 1-13, and Building Area (12 apartments): 870 Valley Mill Rd Apartments 1-12. Parks and Recreation Department: The plan appears to meet the open space and recreational unit ordinance requirements. The developer is also providing a 20' easement for a bike/pedestrian trail along Abrams Creek. In addition, staff is recommending, as outlined in the M.P.O. Bike Pedestrian Plan, a 10' paved bike/pedestrian trail along Valley Mill Road. (The revised MDP dated 812112009 has addressed the comment regarding the trail). Winchester Regional Airport: We have reviewed the proposed Master Development Plan for Fieldstone Apartments and it appears that this plan should not impact operations at the Winchester Regional Airport. However, this proposed site does lie within airspace of the Winchester Regional Airport and residents in that area may experience noise from over flights of aircraft operating in and out of the Winchester Regional Airport. Potential homeowners/tenants should be forewarned about the proximity of this site to the Winchester Airport. Frederick County Schools: Thank you for providing the requested acceleration lane east of the proposed entrance for a bus stop, a sidewalk to the bus stop and accompanying street signage. The acceleration lane will provide some refuge outside of the Valley Mill Road travelway for eastbound buses. Please be aware that we will not be able to send buses onto this property, as there will be no bus turnaround in the parking lot. Frederick County Public Schools is concerned about all land development applications. Both capital expenditures and annual operating costs are increased by each approved residential development. Planning & Zoning: A) Master Development Plan Requirement A master development plan is required prior to development of this property. Before a master development plan can be approved, it must be reviewed by the Planning Commission, Board of Supervisors and all relevant review agencies. Approval may only be granted if the master MDP #02-09, Fieldstone Apartments September 1, 2009 Page 4 development plan conforms to all requirements of the Frederick County Zoning and Subdivision Ordinances. The purpose of the master development plan is to promote orderly and planned development of property within Frederick County that suits the characteristics of the land, is harmonious with adjoining property and is in the best interest of the general public. B) Location The subject property is located on the south side of Valley Mill Road (Route 659), 0.5 miles east of Greenwood Road. C) Site History The original Frederick County Zoning Map (U.S.G.S. Stephenson Quadrangle) identified the zoning for the acreage within the master development plan as A-2 (Agricultural General) District. On September 9, 1987 the Board of Supervisors approved Rezoning #23-87 which rezoned the site from the A-2 District to the RP (Residential Performance) District. The 5.58 acre site was originally part of a 108 acre parcel; the remainder of the site is part of the Arcadia development. D) Site Suitability & Project Scope Comprehensive Policy Plan: The Frederick County Comprehensive Policy Plan is an official public document that serves as the community's guide for making decisions regarding development, preservation, public facilities and other key components of community life. The primary goal of this plan is to protect and improve the living environment within Frederick County. It is in essence a composition of policies used to plan for the future physical development of Frederick County. [Comprehensive Policy Plan, p. 1-1] Land Use Compatibility: The parcel comprising this MDP application is located within the County's Urban Development Area (UDA) and Sewer and Water Service Area (SWSA). The Urban Development Area defines the general area in which more intensive forms of residential development will occur. In addition, the Eastern Frederick County Long Range Land Use map designates the general area in which the Fieldstone Apartments development is located for residential land uses. The Fieldstone Apartments project will develop with a density of 4.48 units per acre. Site Access and Transportation: This proposed development will be accessed via one entrance on Valley Mill Road with a right turn lane and an acceleration lane. The development will also be constructing a ten foot paved trail along a portion of the Valley Mill Road frontage and then transitioning to a trail along the creek. The Eastern Road Plan of the Comprehensive Policy Plan shows Valley Mill Road as an improved major collector road (UD4). While this development will not be constructing roads other than a turn land and an acceleration lane, they have demonstrated that there is sufficient right-of-way available on the southern side of Valley Mill Road for future improvements. MDP #02-09, Fieldstone Apartments September 1, 2009 Page 5 Buffers and Screening: A reduced 50 foot road efficiency buffer will be provided along a portion of Valley Mill Road; this buffer will consist of six foot berm and a single row of evergreen trees. The remainder of the Valley Mill Road frontage will have an 80 foot full road efficiency buffer; this buffer will consist of a double row of evergreen trees. A 100 foot full screen residential buffer is being provided along the residential property to the west; this buffer will consist of a six foot opaque fence and three trees per ten linear feet (1/3 evergreen trees, 1/3 deciduous trees, 1/3 shrubs). Environmental Features: The Fieldstone Apartments property does contain various environmental features, including floodplain and steep slopes. Abrams Creek runs through the rear of this property and the limits of the 100 year floodplain are shown on the MDP. This property has received a Conditional Letter of Map Revision from FEMA for the proposed floodplain modifications. The site also has small areas of steep slopes as indicated on sheet 3. STAFF CONCLUSIONS FOR THE 09/16/09 PLANNING COMMISSION MEETING: The Master Development Plan for the Fieldstone Apartments property depicts appropriate land uses and appears to be consistent with the requirements of Article VIII, Master Development Plan, of the Zoning Ordinance, and this MDP is in a form that is administratively approvable. All of the issues brought forth by the Planning Commission should be appropriately addressed prior to a recommendation to the Board of Supervisors. It appears that the application meets all requirements. Following presentation of the application to the Planning Commission and the Board of Supervisors, and the incorporation of your comments, staff is prepared to proceed to approval of the application.

However, this proposed site does lie within airspace of the Winchester Regional Airport and residents in that area may experience noise from overflights of aircraft operating in and out of the Winchester Regional Airport. Potential homeowners/tenants should be forewarned about the proximity of this site to the Winchester Airport. We appreciate the opportunity to review these plans and your cooperation in ensuring the continuing operations of the Winchester Regional Airport. Sincerely, F* %a�W�K'5, Serena R.

We offer the following comments: Thank you for providing the requested acceleration lane east of the proposed entrance for a bus stop, a sidewalk to the bus stop, and accompanying street signage. The acceleration lane will provide some refuge outside of the Valley Mill Road travelway for eastbound buses. 2. Please be aware that we will not be able to send buses onto this property, as there will be no bus turnaround in the parking lot.

Based on our meeting with you on June 23, 2008 and internal discussions, Frederick County Public Schools would like to offer the following comments: The cumulative impact of this project and other projects in various stages of development in eastern Frederick County will necessitate future construction of new schools and support facilities to accommodate increased student enrollment. We estimate that the 25 multifamily units in this development will house 1 high school student, 1 middle school student, and 2 elementary school students. In order to properly serve these 4 students, Frederick County Public Schools will outlay $139,000 in capital expenditures and $41,000 annually in operating costs. You will find, enclosed with this letter, a more detailed assessment of the impact of the Governors Hill development on FCPS, including attendance zone information. 2. As there is the possibility that, from time to time, a larger number of students than anticipated will live in these apartments, please provide an acceleration lane east of the proposed entrance, which will serve as a bus stop for eastbound buses. Also, please provide a sidewalk to this bus stop. The acceleration lane will provide some refuge outside of the Valley Mill Road travelway for eastbound buses. As discussed, the acceleration lane should be 100 feet in length from the centerline of the proposed entrance and should further include a taper to allow buses to easily move out of the acceleration lane. 3. Please provide street signage indicating both that there is a school bus stop ahead and the school bus stop itself. Frederick County Public Schools is concerned about all land development applications. Both capital expenditures and annual operating costs are increased by each approved residential development, as is illustrated above and in the attached development assessment.

Revise the ROW widths shown on sheet 2 and the detail on sheet 3. Response: 3' road maintenance easement is added on the plan see sheet 2. We have revised and added 3 feet for road maintenance easement on the "Absolute Minimum Right of Way for Typical UD4 Road Section". This detail is only for the purpose to show there is enough room for UD4 and road maintenance easement in front of this property, see attachment. Comment 2: Pedestrian Facility. For the trail along the stream it seems it wasn't continued to the property line, extend the lines to ensure it goes to the property line. Response: Complied. the I O' trail is extended to the property line see sheet 2 of 3 Thank you for your assistance with this project. Contact us with any questions or need for additional information.

Per Eastern Road Plan, Valley Mill Road is an improved major collector road (UD4). The MDP shows Valley Mill Road with variable width right of way; if adequate ROW isn't currently available, it needs to be shown on this MDP and dedicated. Response: Minimum right-of-way width for UD4 is 73' or 36.5' (half) measured from centerline (see details shown on sheet 3 of 3). The existing right-of-way width measured from the existing centerline of Valley Mill Road to the property line varies from 36.6' to 39.5' (see plan sheet 2 of 3). Comment 2: Pedestrian Facility. The ten foot trail needs to be constructed with this development. While constructing the trail along Valley Mill may not be feasible due topography, the trail could be relocated as shown on sheet 2 to run adjacent to the creek. Response: The 10' trail will be constructed with this development and it has been relocated and extended as shown on sheet 2 of 3. Comment 3: Residential Buffer. The MDP shows a picnic shelter within the inactive portion of the residential buffer, this needs to be relocated. Response: The picnic shelter is relocated away from the inactive portion of the residential buffer (see sheet 2 of 3).

Response: Detail is revised (see sheet 2 of 3). Comment 5: Recreational Amenities. On the coversheet, provide a statement regarding the amenities being provided with the development (tot lot / shelter). Response: Note is added on cover sheet to indicate the recreational amenities shall be provided with this development such as tot lot and picnic shelter. Comment 6: Building Separation. The coversheet lists a ten foot separation for buildings; clarify where this minimum comes from, as it is not a requirement listed in the Zoning Ordinance, Response: It is correct there is no minimum separation in zoning ordinance. However, the maximum units allowed in one building are 16 units. Since we are proposing 25 units, we are required to have two separate buildings. The fire rated regulates the minimum building separation and the note is revised to clarify this issue (see cover sheet). Comment: Approvals are required from the following agencies: Frederick County Department of GIS. Response: Copy of approval letter from GIS is attached. Thank you for your assistance with this project. Contact us with any questions or need for additional information.

Per the Floodplain District of the Zoning Ordinance and the Flood Boundary and Floodway Map, this site is located in the Floodway District. In accordance with the Floodway District, no disturbance is permitted "unless it has been demonstrated through hydrologic and hydraulic analysis performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in the one -hundred - year flood elevation. " Response: Greenway Engineering has received a Conditional Letter of Map Revision (CLOMR) from FEMA (Case No.: 08-03-1186C). The CLOMR based on fill for the property reflects all proposed disturbances to the floodplain and floodway (copy of the FEMA CLOMR attached). Comment 2: Floodway District Permitted Uses. Per §165-115 structures are not permitted in the Floodway District. In order for this MDP to proceed further, the district boundary must be changed by the US Army Corps of Engineers and approved by the Federal Insurance Agency and Frederick County Public Works Department. Response: Greenway Engineering has received a Conditional Letter of Map Revision (CLOMR) from FEMA (Case No.: 08-03-1186C). The CLOMR based on fill for the property reflects all proposed disturbances to the floodplain and floodway (copy of the FEMA CLOMR attached).

Per the Eastern Road Plan, Valley Mill Road is an improved major collector road (UD4). The improvements associated with this roadway need to be provided along the entire frontage of this site. Response: Valley Mill Road improvements have not been provided. There are no proffer commitments to complete road improvements associated with this project. Additionally, the impacts associated with the projected 166 VPD generated by the development do not warrant this type of improvement. Valley Mill Road is completely developed between Greenwood Road and Channing Drive; therefore, there are no other project commitments. to improve this segment of Valley Mill Road. Comment 4: Pedestrian Facility. The ten foot trail needs to extend along the entire frontage of the site as indicated on sheet 2. A detail for the trail also needs to be provided instead of the sidewalk detail. Response: The ten -foot trail extends across the limits of the site improvements. East of the site improvements, the steep terrain and the distance from the existing road to Abrams Creek would make constructing a trail very difficult. Therefore, a 20' easement has been provided for a possible trail to be extended along Abrams Creek and the location of the trail has been approved by Frederick County Parks and Recreation. The owner, Ben Butler, had a meeting with Eric Lawrence in regards to this issue in July 2008. According to Eric Lawrence, either a sidewalk or a bike trail is required along the front of the property on Valley Mill Road and that requirement cannot be waived. Per conversation between Ginny Harvey of Greenway Engineering and Eric Lawrence, Ginny indicated to him the difficulty on the eastern end of the property that the building of either a sidewalk or a bike trail over the eastern boundary of the property will be nearly impossible to build because of the terrain. What Greenway Engineering came up with, and Eric agreed to be a reasonable solution, would be to build the bike trail along the front of the property and at that point where it reached the end of the parking lot, have it bend in a southeasterly direction to tie in with the 20-foot proposed bicycle right-of-way. This would avoid the eastern boundary of the property and building in the wetlands. Please let me know if you feel that this is a reasonable solution that can be implemented for the Master Development Plan and the Site Plan. A detail for the trail has been added to sheet 2; the sidewalk detail has been removed. Comment S: Entrance Location. The entrance for this development needs to align with the driveway across Valley Mill Road. Response: The entrance location has been approved by VDOT and per our recent TRC meeting on June 18, 2009, the proposed entrance as shown on previous MDP plan submission is acceptable. File #2160E/NA/dlm Comment 6: Proposed Use. On the coversheet, revise the proposed use to "garden apartments ". Response: The use has been revised to "garden apartments" on the cover sheet. Comment 7: Open Space. Fifty percent of the required open space must be outside of environmental features. The MDP shows that only 10.2% of the open space is useable due to buffers and environmental features. Response: Open space tabulations on the cover sheet have been expanded upon. The tabulations show that more than 50% of the required open space is located outside environmental features. (Required open space is 1.67 acres, provided open space outside the environmental features is 1.31 acres or 78.4%) Comment 8: Acreage Breakdown. The coversheet needs to account for acreage in the housing type and in road right-of-way. Response: The coversheet land use tabulations have been expanded to include acreage in the housing type that includes the parking area. There will not be any right-of-way dedication as part of this project and has not been included in tabulations. Comment 9: Units per building. Under dimensional requirements on the coversheet, it needs to show that only 16 units are permitted per structure. Response: The dimensional requirements on the coversheet have been expanded upon to include the following: Maximum number of units/building — 16 units/building. Comment 10: Utilities. Provide the location of all utilities (gas, electric) on the MDP. Response: Location of dry utilities (gas, electric) is not a requirement of the MDP. The location of existing and proposed water and sewer are shown on the MDP. Comment H. Water and Sewer Availability. A statement needs to be on the coversheet that states water and sewer is available and will be provided by the FCSA. Response: The following statement has been added to coversheet: Water and sewer is available and will be provided by FCSA. Comment 12: Reduced Road Efficiency Buffer. The buffer detail on sheet 2 does not reflect ordinance requirements. Also, the buffer detail appears to have the pedestrian trail on top of the six foot berm. The buffer needs to extend the entire frontage of the property. Response: The reduced road efficiency buffer detail has been revised to reflect ordinance requirements. The pedestrian trail has been moved to be adjacent to the right-of-way to avoid the berm. The buffer has been extended to the eastern property line. The extended portion is a full distance road efficiency buffer. File #2160E/NA/dlm Comment 13: Surveyed Boundaries. The surveyed boundaries for the property need to be shown on the MDP. Response: The surveyed boundaries for the property have been added to sheet 2. Comment 14: Residential Separation Buffer. The separation buffer needs to account for a six- foot opaque element. Response: A six-foot high opaque element has been added to separation buffer detail. Comment 15: Steep Slopes. Sheet 3 of the MDP states that 30% of the steep slopes are being disturbed. Per the Zoning Ordinance, only 25% of the site's steep slopes may be disturbed. Response: The steep slope area has been recalculated to 0.17 acres. The steep slopes that are being disturbed for purposes of constructing the trail and berm in the road efficiency buffer equal 0.02 acre, which equates to 11.76% (below the maximum allowable of 25%). General Comment: Review comments are required from the following agencies: Frederick County Department of Parks & Recreation, Frederick County Public Schools, Frederick County Fire Marshal, Frederick County Department of Building Inspections, Frederick County Department of Public Works, Frederick County Department of G.I. S, Frederick County Sanitation Authority, and the Virginia Department of Transportation. Response: Approval letters are attached for all of the requested agencies.
