PROJECT DESCRIPTION The project consists of construction of roadways, parking, a school building and playground, and other items associated with the proposed commercial property addition. The total lot size is approximately 5.00 acres. EXISTING SITE CONDITIONS Vegetative Cover — The site is covered in well -maintained dense mixed grasses of hay quality. Topography — The site sits at the top of its drainage basin with no significant drainage above it. It slopes toward two drainage points. The more significant point is in a small gully located midway on the western property line. All construction and land disturbance activities drain to this point. A small slope runs to the southwest corner of the property, but no land will be disturbed in this area, and consequently no E&S measures are instituted. Slopes over the entire site are approximately 2.5%, with no slope greater than 5%. ADJACENT PROPERTIES The site is bounded on the north side by West Parkin's Mill Road, on the east and south sides by a lot owned by Oakcrest Builders (the developer of this lot) and zoned RA, and on the west side by a lot owned by Baker and zoned RA. SOILS The following soil is contained within the site. Soil Name Soil Erosion Permeability Depth Identifier Hazard Blairton Silt" 3B Moderate Moderately' To 30 " Loams, 2 to slow " inches 7 percent slopes " CRITICAL EROSION AREAS The most critical erosion area is in vicinity of the gully where the drain water concentrates. However, E%S measures will easily accommodate the expected flows. EROSION AND SEDIMENT CONTROL MEASURES Unless otherwise noted, the structural and vegetative practices shall be constructed and maintained according to the Minimum Standards of the Virginia Erosion and Sediment Control Law, Regulations and Certification Regulations and Specifications outlined in the latest edition of the Virginia Erosion and Sediment Control Handbook. The following summary(s) are for quick reference only and do not preclude any requirements or standards listed in the Virginia Erosion and Sediment Control Handbook. Also, other measures not specifically listed here or on the construction plans may be required to keep the site within regulatory compliance during construction. The need for such items may not be evident until the beginning of construction. The County Public Works Director will determine the need for additional erosion and sediment control measures. STRUCTURAL PRACTICES Temporary Construction Entrance - 3.02 Two temporary construction entrances shall be constructed as shown on the Erosion and Sediment Control Plan. The entrances shall be maintained in a condition that prevents tracking or flow of mud onto public rights -of -way. This may require periodic top dressing with additional stone or washing and reworking of existing stones as conditions demand and repair and/or clean -out of any structures used to trap sediment. All materials spilled, dropped, washed or tracked from vehicles onto roadways or into storm drains must be removed immediately. During wet weather conditions, construction vehicle drivers will be required to wash their wheels prior to entering the highway. During the washing process, the contractor shall ensure that the runoff created by the washing process is passed through one of the sediment removing devices such as a section of silt fence. Water for washing operations shall be hauled to the site or shall be acquired from a hydrant installed at the site. This hydrant shall be installed in accordance with the County of Frederick specifications. The use of water trucks to remove materials dropped, washed or tracked onto the roadways will not be permitted under any circumstances. 2. Construction Road Stabilization - 3.03 Construction road stabilization shall be utilized wherever stone -based roads or parking areas are to be constructed, whether permanent or temporary, for use by construction traffic. Treated areas are likely to require periodic top dressing with new gravel. Seeded areas adjacent to road and parking areas shall be check periodically to ensure a vigorous stand of vegetation is maintained. Roadside ditched and drainage structures shall be checked regularly to ensure they do not become clogged with silt or other debris. 3. Silt Fence Barriers - 3.05 Silt fence barriers shall be installed at locations shown on the Erosion and Sediment Control Plan to filter sediment -laden runoff and decrease the velocity of sheet flows and low -to -moderate level channel flows. Wire reinforced silt fences are required. 4. Temporary Sediment Basin - 3.14 Temporary sediment basin shall be constructed at the location shown on the Erosion and Sediment Control Plan. The temporary sediment basins shall remain in place after construction and final site stabilization are completed to serve as permanent stormwater management structures. Refer to the Erosion and Sediment Control Details for outlet design and retrofitting. 5. Outlet Protection - 3.18 All storm pipe outlets shall be protected with a stone apron per specifications outlined in the latest edition of the Virginia Erosion and Sediment Control Handbook. When installed properly, outlet protection should require very little maintenance. However, it M ' shall be inspected periodically for scour from high flows. Care must be taken to properly control sediment -laden construction runoff draining to the outlet protection until all up - gradient areas have been fully stabilized. 6. Dust Control - 3.39 The contractor shall take measures to reduce the surface and air movement of dust, which may present health hazards, traffic safety problems or harm animal and plant life during land disturbing and construction activities. ' GRASS ESTABLISHMENT 1. Topsoil Stockpile - 3.30 Topsoil shall be stripped from areas to be graded and stockpiled for future use. The County Erosion and Sediment Control Administrator shall approve stockpile locations. Stockpiles shall be temporarily seeded and protected with silt fence. When the topsoil is spread over the graded areas, it shall be placed in 2-4 inch compacted lifts. Topsoil hauled offsite shall be disposed of in an approved area as directed by the County Erosion and Sediment Control Administrator. 2. Temporary Seeding - 3.31 The topsoil stockpiles and all areas to be rough graded during the course of the project ' shall be immediately seeded with temporary vegetation upon completion of grading operations. The appropriate seed mixture will be dependent upon the time of year it is to be sown. The typical County seed mixture specification is shown on the Erosion and Sediment Control Details. The County Erosion and Sediment Control Administrator must ' approve any deviation from these mixtures. NOTE: Stabilization measures shall be applied to earthen structures such as dams, dikes, ' diversions, and sediment basin embankments immediately after construction of the said structure. ' 3. Permanent Seeding - 3.32 Permanent seeding shall be completed within seven days from achieving final grade of the site. MANAGEMENT STRATEGIES The following guidelines shall be utilized in the planning of construction: 1. The silt fence, the sediment basin, and the construction entrance and other measures intended to remove sediment shall be constructed as a first step in the land disturbing activity and shall be ' functional before up slope land is disturbed. These measures shall also be stabilized with vegetation prior to up slope land disturbance. ' 2. The contractor shall install inlet protection for all storm utilities immediately after installation of said structures to prevent sediment from collecting in the said structures and being deposited down stream. ' 3. Construction shall be sequenced so that grading operations can begin and end as quickly as I possible. I 4. Temporary seeding and other stabilization shall follow immediately after the site is stripped of topsoil if it is determined that final grading will not begin within 30 days. I5. The developer shall be responsible for the installation and maintenance of all Erosion and Sediment Control practices. NOTE: The contractor shall install sediment trapping and tree protection measures as the first step in construction. Once in place, the contractor shall strip topsoil and begin grading operations. The contractor shall ensure that at the end of each working day all erosion and sediment control measures are in place and functioning properly. This will be strictly enforced. These controls shall be in effect during the remaining development, which includes final grading, utility construction, and paving. CONSTRUCTION SEQUENCING NOTES: The following construction sequence shall be utilized to ensure that the proper erosion and sediment control practices are in place, and fully operational prior to upslope land disturbance. Sequence"A" 1 — install the Construction Entrances. 2 — install Sediment Basin. 3 — install Silt Fences. 4 — install Outlet Protection and Flared End Sections as appropriate. STORMWATER MANAGEMENT CONSIDERATION Changes to parking areas will increase peak runoff. Existing storm water facilities were designed and shall be installed in accordance with the accompanying plans, and no modifications are necessary. PERMANENT STABILIZATION Permanent stabilization shall be applied to denuded areas immediately after final grade is ' achieved on any portion of the site. Temporary soil stabilization shall be applied within seven days to denuded areas that may not be at final grade but will remain undisturbed for more than 30 days. Permanent stabilization shall be applied to areas left dormant for more than one year. Seeding shall be conducted in accordance with the latest edition of the Virginia Erosion and Sediment Control Handbook. Permanently seeded areas shall be protected during establishment with straw mulch. Hydro -seeding also requires straw mulch protection. ' MAINTENANCE ' In general, all erosion and sediment control measures shall be checked daily and after each rainfall. The following items shall be checked in particular: 1. The silt fence, inlet and outlet protection areas, and temporary construction entrances shall be checked for undermining, deterioration, and functioning ability. 2. All seeded areas shall be checked for adequate growth. If adequate growth is not evident, the area shall be re -seeded to prevent the soils from eroding. 3. All temporary erosion and sediment control measures shall be removed only when authorized by the Frederick County, Virginia Erosion and Sediment Control Administrator. 4. Trapped sediment and the disturbed soil areas resulting from the removal of the temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. 5. Long term maintenance of all stormwater associated items is the sole responsibility of the owner. 7 CRIAID ENGINEERING EROSION & SEDIMENT CONTROL CALCULATIONS Winchester Montessori School Frederick County, Virginia CD-081 11 January 2002 Dennie D.

Box 1448 Harrisonburg, Virginia 22802 RE: Site Plan Comments - Winchester Montessori School Frederick County, Virginia Dear Dennie: Upon review of the subject site plan, we offer the following comments: 1) The site plan indicates that there is a downstream pipe under the road located on the Baker property. The post -developed ten (10)-year storm release from the pond cannot exceed the capacity ofthe subject pipe. Provide the size of the existing pipe and an analysis to verify the capacity of this pipe. If the capacity of the pipe is less than the ten (10)-year storm release, the flow rate from the pond must be reduced. The other option would be to replace the downstream pipe for the neighbor if its undersized. 2) The pre -development "C" coefficient used in your calculations for this site is 0.35. We require that the "C" values of 0.25 to 0.30 be used for these soil types and site conditions. 3) Due to changes in site conditions, the time of concentration should changed by a few minutes from pre -developed to post -developed. 4) The stormwater that drains to the east of the site shall be analyzed separately to ensure that an adequate drainage channel exists in accordance with Virginia Erosion and Sediment Control Law Minimum Standard 19. 5) The detail for the proposed wash rack shall include a wash rack cattle guard or the construction entrance shall be twice the length proposed. 6) The plan indicates an anti -vortex collar for the proposed sediment basin. Provide a a detail which indicates the type of device proposed. A CMP is not recommended. 7) Place the responsible land disturber title block on Sheet C-I as shown. 107 North Kent Street - Winchester, Virginia 22601-5000 ,k Winchester Montessori School Page 2 December 6, 2001 8) Note 3 on Sheet 7 of the erosion and sediment control narrative shall read "Frederick County, Virginia Erosion and Sediment Control Administrator".

Before staff is able to approve the site plan, you will need to prepare a revised site plan that addresses each ofthe following comments. I am providing you with a red -marked copy of the site plan to visually assist. Staffs comments areas follows: (1) Location Map. Please label Rt. 50 on the location map, shown on page C-1 of the site plan. (2) Loading Area for Handicap Parking Spaces. Please provide a loading area for each of the proposed handicap parking spaces. In the details section, shown on page C-6, you show a loading space adjacent to the handicap parking spaces. However, on the site plan, shown on page C4, you fail to illustrate these loading areas. It appears that you may have to move the handicap parking spaces back so the loading areas are not in the drive lane. (3) Traffic Flow. Please clarify how traffic will enter and depart the site. If one-way traffic is being proposed, signage needs to be provided to direct the traffic flow. (4) Sanitary Sewer. Please show and label all components of the proposed sanitary sewer. (5) Surface Material. Please provide a minimum surface material of double -prime and seal. (6) Parking Spaces. Loading spaces should not be considered as regular parking spaces when calculating the total number of spaces that should be provided. Please provide four additional parking spaces to satisfy the requirements of the Zoning Ordinance. (7) Business Sign. Please show the location of any future business sign. Details should also be provided if possible. (8) Lighting. Please show and label all proposed lighting fixtures. Detail should be provided. If no lighting 107 North Kent Street • Winchester, Virginia 22601-5000 Page 2 Triad Engineering, Inc. Re: Review Comment for S.P. #52-01 December 17, 2001 fixtures are proposed, provide a statement to that effect on the site plan. (9) Trash Disposal. Please expand on your statement regarding trash disposal on page C4. You should explain how trash will be disposed of. (10) Subdivision of Property. Prior to approval of this site plan, the proposed lot must be approved by the Frederick County Zoning & Subdivision Administrator and a copy of the recorded plat should be provided to me. (11) Landscaping. Although landscaping is not required by the Zoning Ordinance for schools in the RA Zoning District, I "recommend" that you provide a landscaping screen along the left property line to screen the proposed parking lot from any potential residential dwellings. Perimeter and interior parking lot landscaping is also "recommended." (12) Future Road Improvement Project. West Parkins Mill Road is identified as an improved major collector road by the Frederick County Comprehensive Plan. Therefore, the Virginia Department of Transportation may require additional lands if it is determined to be needed for future road improvements. Please address this issue prior to site plan approval. VDOT's review comments should adequately address this issue when done. It would be prudent to plan for this future right of way acquisition during this site development plan. After you have revised the site plan, please resubmit one copy so that I may verify the information contained on the plan. I will need all approved review agency comment sheets and at least five copies of the final plan for approval. Comment sheets are required from the following agencies: the Virginia Department of Transportation (VDOT), the Inspections Department, the Frederick County Engineer (Public Works), the Frederick County Fire Marshal, the Frederick County Department of Parks and Recreation, and the Frederick County Health Department. Do not hesitate to call me, if you have any questions or concerns regarding this letter. Sincerely, Jeremy F.

Tax Map 9 77-A-26B; Heafffi Dept. ID 4 LDS-069-00-10. Dear Mr. Schofield: Enclosed is a revised discharging application for the proposed Winchester -Montessori School to be located on Rt. 644 in Frederick County. The applicant and his consultant have proposed a new discharging point further back into the property to allow mom flexibility in locating the new building. The new discharge channel merges with the pre%zously proposed channel approximately 60 feet before exiting the property. 'Me Frederick County Health Department has no objection to this proposed change. I do have two recommendations regarding the site: 1, The discharge ehanntl should be "ditched out" to prevent ponding and to promote better flow. 2. The discharge channel should be riprapped for at least the first 100 feet Also, since this building is proposed as a school, it would be prudent to fence off the entire channel and treatment system to discourage access to the children. Since this application is for a non-residential system of less than 1000 grpd,1 am forwarding it to your office for further processing If you have any questions, please call me at (540) 722-3430 Sinccr y, John Dailey Environmental Health Specialist cc: Jim Vickers, owner Bruce Legge, consultant
