Box 2397 Winchester, VA 22604 RE: Kraft Foods, Inc. Parking Lot Expansion, Site Development Plan #071-98 Dear Steve: I have had the opportunity to review the above referenced site plan submitted to our department on December 3, 1998. The following comments are offered and should be addressed during the revision of this site plan. I have also marked the enclosed plan for your use. 1) On the cover sheet, please provide the name, address, and phone number of the developer. 2) Please state the parking lot setback requirements for the M1 Zoning District on the notes and legend sheet and ensure that these setbacks are clearly delineated on the site plan. Furthermore, the building setback line shown adjacent to West Brooke Road (Route 1320) should be modified from twenty-five (25) feet to the correct requirement of seventy-five (75) feet on the existing conditions sheet. 3) Please extend the sidewalk that is shown terminating just beyond the handicapped space to the end of the south row of proposed parking spaces. It is recommended that this extension consist of a four (4)-foot concrete sidewalk. 4) Please ensure that all lighting is controlled to prevent glare beyond the lot line. A statement to this effect should be included within the plan. Furthermore, please include specifications of the outdoor lighting fixtures identified on the site plan. 5) Please identify the state route numbers applicable to both Park Center Drive and West Brooke Road on the site plan. 6) Please correct the calculation regarding the parking requirement for the 21,500 square -foot office facility on the notes and legend sheet. The number of required parking spaces for this use should be eighty-six (86) rather than one hundred (100). The total number of required parking spaces should be adjusted to reflect this correction. Furthermore, please provide a breakdown of the total number of spaces provided for the facility. Such a breakdown should delineate both the number of existing spaces and the number of spaces proposed as part of this expansion. 107 North Kent Street - Winchester, Virginia 22601-5000 ia • 0 Kraft Foods, Inc. Site Plan Review Page 2 December 21, 1998 7) Please state the required number of handicapped parking spaces for the subject site, as well as the number provided through both previous development and the proposed expansion. The location of all existing handicapped spaces should be shown on the existing conditions sheet. 8) Please increase the number of landscape plantings along the perimeter of the expanded parking area to ensure the provision of shade trees at the required interval of one (1) per every forty (40) feet of parking spaces. Specific attention should be given to the area located between the existing parking area and the proposed expansion lot, which does not include any vegetation. It is recommended that shade trees be planted along the requested sidewalk extension to provide adequate shading for the parking spaces immediately adjacent to this area. As the area in question constitutes a significant drainage -way, it may be necessary to modify the grading of this area to accommodate both the sidewalk and landscape plantings. Furthermore, please change the height of the boxwood shrubs identified in the plant schedule from one (I) -foot to the required three (3) feet. The three-foot height is necessary to adequately mitigate the impact of headlight glare on adjacent properties and rights -of -way. After you have revised the site plan, please resubmit one copy so that I may verify the information contained on the plan. I will then need all approved review agency comment sheets and five copies of the final site plan for approval. Comment sheets are required from the following agencies: the Virginia Department of Transportation, the Frederick County Sanitation Authority, the Frederick County' Inspections Department, the Frederick County Engineer, and the Frederick County Fire Marshal.

PARKING LOT EXPANSION FREDERICK COUNTY, VIRGINIA ISTORMWATER MANAGEMENT NARRATIVE KRAFT FOODS INC. EXPANSION FREDERICK COUNTY, VIRGINIA ' TRIAD PROJECT NO. CD-025 IProject Description ' The purpose of this project is to construct additional parking to accommodate the increased parking requirements for the interior building renovations. The site is located in the Fort Collier ' Industrial Park, west of the intersection of Park Center Drive and West Brooke Road. 0 7 FI Existing Site Conditions The site consists of 19.98 acres and slopes from the west to the east. The site currently consists of a manufactu.ring facility, on -site parking lot and loading dock, stormwater management facility, and associated underground utilities. Existing drainage ditches convey stormwater runoff along the east, west, and south sides of the site to the stormwater management pond located in the southeast corner of the site. Adjacent Areas This site is bordered on the north by existing train tracks with a vacant drive-in movie theater and Moore's lumber yard on the north side of the train tracks. To the east, the site is bordered by Park Center Drive with a vacant lot and Green Bay Packaging, Inc. Manufacturing facility on the east of Park Center Drive. West Brooke Road borders the site to the south with a vacant lot to the south of West Brooke Road. The property is bordered to the west by a vacant lot. Pre -Devel amen t Runoff The pre -development peak runoff was determined for the 2, 10, and 25 year storms, using TR-55. The adjacent undeveloped areas consist of a mixture of brush, weeds, and grass. We will assume that the Kraft site consisted of similar ground cover prior to the initial development of the site. Based on the existing topography, it is assumed that 19.11 acres of the pre -developed site will flow to the point where the stormwater management pond discharges. Included in the 19.11 acres is 1.77 acres of VDOT right-of-way, and ' Stormwater Management Narrative Kraft Food's Parking Lot Expansion ' Frederick County, Virginia Page 2 railroad property. Computer print-outs for the pre -development ' runoff calculations are located in Appendix A. A summary of the pre -development peak runoff follows: ' 2 Year storm = 5 cfs 10 Year storm = 19 cfs ' 25 Year storm = 26 cfs Allowable Pond Discharge ' The allowable discharge from the stormwater management facility is the pre -development peak runoff. Post -Development Detained Runoff ' The post -development peak runoff was determined for the 2, 10, and 25 year storms in the same method as the pre -development runoff. Based on the existing site conditions and the proposed ' design for the parking lot expansion, the same 19.11 acres of the site will be detained. The ultimate development of the site will ' consist of 10.62 acres of pavement or building, 0.25 acres of gravel, and 8.24 acres of lawn. Computer print-outs for the post - development detained runoff calculations are located in Appendix B. ' A summary of the post -development peak runoff follows: 2 Year storm = 28 cfs ' 10 Year storm = 55 cfs 25 Year storm = 68 cfs I Stormwater Routin The stormwater routing was performed using the Pondpack ' computer program by Haestad Methods, Inc. Routing was performed on the existing outlet structure which consists of a 15 inch inlet ' pipe in addition to a 4 foot square outlet box with 4 orifices.

PARKING LOT EXPANSION FREDERICK COUNTY, VIRGINIA TRIAD PROJECT NO. CD-025 Project Description The purpose of this project is to construct two additions parking lots to support the increased parking requirements of the renovated building. The two parking lots will be on either side of the truck drive. The site is located west of the intersection of Park Center Drive and West Brooke Road. Existing Site Conditions The site consist of the existing Kraft Foods, Inc. Manufacturing facility. The areas where the new parking lots are to be constructed consist of open space. The site slopes gently from the west to the east. An existing drainage ditch and storm sewer culverts convey the stormwater runoff to the existing detention pond. Adjacent Areas This site is surrounded on the north and east by Park Center Drive and West Brooke Road respectively. The property to the north of Park Center Drive consists of a vacant lot and the Green Bay manufacturing facility. The property to the east of West Brooke Drive is vacant. A vacant lot exists to the south to the Kraft Foods, Inc. site. The property is bordered on the west by the CSX railroad. To the west of the railroad is Moores Lumber Yard and the abandoned Dirve-In Movie Theater. Soils The area of proposed construction is situated within the Opequon-Chilhowie silty clay, very rocky (33C) soils according to the Soil Survey of Frederick County, Virginia published by the U.S. Department of Agriculture, Soil Conservation Service. This soil is found on narrow to moderately broad, convex valley sides. The � I Erosion and Sediment Control Narrative Kraft Foods, Inc. Parking Lot Expansion Frederick County, Virginia Page 3 slopes for this soil type range from 3 to 15 percent. Typically, the surface layer of Opequon soil is a dark yellowish brown silty rclay loam about 3 inches thick. The subsoil is brown silty clay loam and reddish brown clay to a depth of about 15 inches. ' Limestone bedrock is at a depth of about 15 inches. Typically, the surface layer of Chilhowie soil is a dark yellowish brown silty clay loam about 7 inches thick. The upper ' part of the subsoil is a brown clay to a depth of about 12 inches. The lower subsoil is a dark yellowish brown clay. The substratum ' is yellowish brown very channery silty clay to a depth of about 27 inches. Limestone bedrock is at a depth of about 27 inches. ' The soil type is shallow to moderately deep, gently to strongly sloping, and well drained. The permeability rate of the soil is 0.2 to 2.0 inches per hour. The erodibility factor (K) is ' 0.32, the hydrological group is C and the depth to the high water table is greater than 6 feet. iCritical Areas Due to the relative flatness of the site, the only apparent area which may potentially will be the steep slope areas around the perimeter of the parking areas. Erosion and Sediment Control Measures ' Unless otherwise indicated, all vegetative and structural erosion and sediment control practices will be constructed and maintained according to minimum standards and specifications of the ' Virginia Erosion and Sediment Control Handbook. The minimum standards of the VESCR will be adhered to unless otherwise waived or approved by a variance. Erosion and sediment control practices will be in place along ' the low side of all disturbed areas. These practices are to remain in place and maintained until stabilization has been achieved on the construction site. F Erosion and Sediment Control Narrative Kraft Foods, Inc. Parking Lot Expansion Frederick County, Virginia Page 4 ' Structural Practices ' 1. Silt Fence Barrier (3.05) ' Silt fence sediment barriers will be installed down slope of all graded areas and any topsoil stockpile area to filter sediment - laden runoff from sheet flow as indicated on the Erosion and ' Sediment Control Plan. 3. Culvert Inlet Protection (3.08) ' Culvert inlet protection will be installed around the existing culverts that may receive sediment laden runoff from the ' construction areas. Sediment -laden runoff will be filtered before entering the storm sewer culvert. Management Strategies 1. Construction will be sequenced so that grading operations can ' begin and end as quickly as possible. ' 2. The contractor will be responsible for the installation and maintenance of all erosion and sediment control practices as shown on the plans. Any additional erosion and sediment ' controls required by the Owner or the approving authority shall be installed by the contractor. ' 3. After achieving adequate stabilization, or final site stabilization, the temporary erosion and sediment control measures will be cleaned up and removed. All areas of deposited sediment and disturbed soil resulting from the removal of temporary sediment control measures will be seeded in accordance with the permanent stabilization measures as ' described below. ' Permanent Stabilization Erosion and Sediment Control Narrative Kraft Foods, Inc. Parking Lot Expansion Frederick County, Virginia Page 5 All disturbed areas are to be stabilized within 7 days after the final grade is established. Stabilization will consist of the following: 1. Scarifying the top two inches of the topsoil. 2. Adding pulverized agricultural limestone at a rate of 2 tons per acre. 3. Seeding according to the following permanent and temporary seed mixtures. 4. Fertilizing with 10-10-10 fertilizer spread at a rate of 1,000 pounds per acre. S. Mulching with straw at a rate of 1.5 tons per acre. Permanent seeding shall be spread at a rate of 200 pounds per acre and shall consist of the following seed mixture.

The following items will be checked and any repairs made by the end of the day: 1. Silt fence barriers will be checked for undermining and deterioration of the fabric. Fabric for silt fence will be replaced promptly if the fabric has deteriorated or become ineffective. Sediment deposits should be removed after each storm event. Deposits must be removed when they reach approximately one-half of the height of the barrier. 2. Culvert inlet protection will be checked for deterioration of filter fabric and excess sediment accumulation. Filter fabric will be repaired or replaced as necessary. Sediment will be removed when it has accumulated to one-half the design depth and the trap restored to its original dimensions.
