A total of approximately 28 acres will be disturbed during construction. EXISTING SITE CONDITIONS The subject property front Carters Mountain Road and encompasses 139.3 acres, with 133.5 acres being proposed for residential lots and the balance will be right of way. There are approximately 14.6 acres of critical slopes on the site. The topography is roiling with elevations ranging from about 420 to about 643 feet above mean sea level. The majority of the site is wooded and there are several intermittent unnamed streams on the property. ADJACENT AREAS The 5600 feet of the road navigate through the property. The proposed new Terroir Road will intersect at the western border of the site onto Carters Mountain Road. The northern, southern and eastern boundaries abut to rural/agricultural properties. OFF -SITE AREAS All land disturbing activities shall occur on -site and within the limits of project shown on the plans. At this point, no off -site borrow, waste or grading activity will occur. SOILS This site is located in a geologic area referred to as the Piedmont Physiographic Province. The soils in this geologic area are weathered from the underlying metamorphic bedrock. The naturally occurring soils at this site were found to be moderately to highly (plastic silts weathered from the Catoctin formation which consists of basic lava flows, schist, and gneiss composed of chlorite, plagioclase, amphiobole, and epidote. The soils observed here appear to be weathered from metamorphosed sedimentary soils such as phyllite and schist. The map units on the detailed soil map depicted on the Erosion and Sediment Control Plan, represent the soils in the survey area. The map unit descriptions, along with the soil maps, can be used to determine the suitability and potential of a soil for specific uses, and, precautionary erosion and sedimentation control measures which must be adhered to. They also can be used to plan for the management needed for those uses. The profile of the soil classifications follows: Catoctin, Silt Loam (12C): This moderately deep, strongly sloping (7-15%) soil is well drained on side slopes and narrow convex ridge tops. Usually, the surface layer is dark final grade but will remain dormant (undisturbed) for longer than 30 days. Permanent stabilization shall be applied to areas that are to be left dormant for more than one year. During construction of the project, soil stockpiles shall be stabilized or protected with sediment trapping measures. The applicant is responsible for temporary protection and permanent stabilization of all soil stockpiles on site as well as soil intentionally transported from the project site. Soil stabilization refers to measures that protect soil from the erosive forces of raindrop impact and flowing water. Applicable practices include vegetative establishment, mulching, and the early application of gravel base on areas to be stone. Soil stabilization measures should be selected to be appropriate for the time of the year, site conditions, and estimated duration of use. A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until ground cover is achieved that, in the opinion of the local program administrator or his designated agent, is uniform, mature enough to survive and will inhibit erosion. The construction entrance and all sediment control structures within the corresponding drainage areas shall be installed first and made functional prior to any land disturbing activity in those corresponding drainage areas. Sediment filters and traps, perimeter dikes, sediment barriers and other measures intended to trap sediment shall be constructed as a first step in any land -disturbing activity and shall be made functional before upslope land disturbance takes place. Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions immediately after installation. Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that are found to be eroding excessively within one year of permanent stabilization shall be provided with additional slope ,3tabilizing measures until the problem is corrected. When work in a live watercourse is performed, precautions shall be taken to minimize encroachment, control sediment transport and stabilize work area to the greatest extent possible during construction. Non -erodible material shall be used for the construction of causeways and cofferdams. Earthen fill may be used for these structures if armored by non -erodible cover materials. When a live watercourse must be crossed by construction vehicles more than twice in any six-month period„ a temporary stream crossing constructed of non -erodible material shall be provided. All applicable federal, state, and local regulations pertaining to working in or crossing live watercourses shall be met. The bed and banks of a watercourse shall be stabilized immediately after work in the watercourse is completed. inch. Maintain clear of shrubs and trees. Apply water with a fine spray immediately after each am-9 has been mulched. Saturate to six (6) inches of soil. MAINTENANCE All erosion and sediment control measures must be maintained and repaired immediately to insure continued performance of their intended functions as stated in the Virginia Erosion & Sediment Control Handbook, Thim Edition 1992. In general, all erosion and sediment control measures will be checked daily and after each significant rainfall event. The following items will be checked in particular: a. Should sediment basins or traps be required, they will be cleaned and maintained according to the VESCH. b. All gravel outlets will be checked regularly for sediment buildup that will prevent drainage. If the gravel is clogged by sediment, it shall be removed and cleaned or replaced. C. All silt ifence barriers will be checked regularly for undermining or deterioration of the fabric and repaired as required. Sediment shall be removed after each storm event and when the level of sediment deposition reaches lhalf way to the top of barrier. d. All seeded areas will be checked regularly to see that a good stand is maintained. Areas should be fertilized and reseeded as needed. DISPOSITION OF TEMPORARY MEASURES All temporary erosion and sediment control measures, including the temporary sediment basins, shall be removed within 30 days after final site stabilization is achieved or after the temporary measures are no longer needed, unless otherwise authorized by the local program administrator. Trapped sediment and other disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. STORMWATER MANAGEMENT A waiver of stormwater detention requirements is requested for this project. The runoff from culverts will increase the velocity of the runoff in some instances, but will dissipated by utilizing outlet protection in the form of riprap. Erosion control stone placed at the end of these outfalls will protect the channels and decrease the flow velocity. To address Best Management Practices, a riparian easement of a minimum 100-foot width will be placed along the intermittent stream in the southern portion of the property and three additional stream buffers are proposed along other intermittent streams. brown and dark yellowish brown silt loam about five (5) inches thick.

Specific Application: Temporary seeding shall be applied to all denuded areas prior to permanent stabilization in the form of either hardscape or permanent seeding. Temporary seeding shall be used on all fill slopes and diversions. j). Permanent Seeding (3.32) Establishment of perennial vegetative cover by planting seed on rough -graded areas that will not be brought to final grade for a year or more or where permanent, long-lived vegetative cover is needed on fine -graded areas. Specific Application: Permanent seeding will be applied to all portions of disturbed area. Soil stabilization Blankets & Matting (3.36) Stabilizing disturbed,_areas of a steep, slope, channel, or a shoreline by applying protective covering on a..prepared area. The matting will protect the young vegetation and promote `its establishment while increasing the permissible velocity of turf grass stands. Specific Application: Where the indicated on the plan. i). Tree Protection (3.38) Protection of desirable trees from mechanical and other injury during land disturbing and construction activity. Specific Application: Tree protection shall be applied around specimen trees indicated to be preserved by the Developer. Dust Control 3.39) Reducing surface air movement of dust during land disturbances, demolition or construction activities in areas subject to dust problems in order to prevent soil loss and reduce the presence of potentially harmful airborne substance. Specific Application: Dust control shall be applied as necessary. (4) inches thick. The subsoil is mostly dark red clay about thirty-six (36) inches thick. The substratum below a depth of sixty (60) inches is mostly red silty clay loam. Permeability its moderate, and available water capacity is moderate. Surface runoff is rapid. The hazard of erosion is severe. The subsoil has low shrink -swell potential. Depth to bedrock is generally greater than five (5) feet. Rabun Clay (72C3): This deep, strongly sloping (7-15%) soil is well -drained soil on narrow convex ridge tops and on narrow convex side slopes. Typically, the surface layer is dark red clay loam about four (4) inches thick. The subsoil is mostly dark red clay about thirty-six (36) inches thick. "The substratum below a depth of sixty (60) inches is mostly red silty clay loam. Permeability is moderate, and available water capacity is moderate. Surface runoff is rapid.

Permeability is moderate, and available water capacity is moderate. Surface runoff is rapid. The hazard of erosion is severe. The subsoil has low shrink -swell potential. Depth to bedrock is generally greater than five (5) feet. Starr Silt Loam (7913): This deep, gently sloping (2-7%), well drained soil is on foot slopes, in depressions, and along small drainage ways. Typically, the surface layer of this soil is reddish brown silt loam about eighteen (18) inches thick. The subsoil is mostly reddish brown silty clay loam about thirty-five (35) inches thick. The substratum is reddish brown loam to a depth of sixty (60) inches. Permeability is moderate, and available water capacity is moderate. Surface runoff is medium with moderate erosion hazard. Subsoil has moderate shrink -swell potential. Bedrock is generally at a depth of more that six (6) feet. CRITICAL AREAS There are several critical areas on the site. These include: one intermittent stream crossing, minimal wetlands crossing and several areas of steep slopes greater than 4:1. The wetlands and steep slopes were impacted only where they could not be avoided. Several areas along intermittent streams will be placed into either a riparian easement or stream buffers to address BMP considerations. In addition, all clean water diversions are critical erosion control measures that must be installed as indicated on the plan. EROSION AND SEDIMENT CONTROL MEASURES The contractor shall provide, construct and maintain erosion and sediment control measures on the site, in accordance with the Virginia Department of Transportation and the County of Albemarle erosion and sediment control measures (refer to the Erosion and Sediment Control Plan sheet). All vegetative and structural erosion and sediment control practices shall be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook. Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final grade is reached on any portion of the site. Temporary soil stabilization shall be applied within seven (7) days to denuded areas that may not be at PERMANENT STABILIZATION All areas disturbed by construction will be stabilized with permanent seeding immediately following finish grading. All seeds will be approved by the "Virginia Crop Improvement Association," Blacksburg Virginia. Seeding will be done with the following: Two (2) parts Kentucky Bluegrass (Poa pratensis), by weight; minimum 98% purity and 90% germination; maximum 1 % weed seed. Three (3) parts perennial Ryegrass (Labium perrene) by weight; minimum 85% purity and 90% germination; maximum 1 % weed seed. Fifteen (15) parts Falcon Fescue (Festuca arundinacae); minimum 98% purity and 90% germination; maximum 1 % weed seed. Permanently seeded areas shall be protected during establishment. Mulch shall consist of oat or wheat straw, free from weeds, foreign matter detrimental to plant life, and dry. Hay or chopped cornstalks will not be permitted. Mulch and/or lime shall be applied at a rate of two (2) tons per acre. Specifications for fertilizer are FS 0-F-241C, Type 1, solid form; Grade A or B; recommended for grass, with one hundred (100) percent of the elements derived from organic sources of the following properties: a) Nitrogen 12.0 % b) Phosphoric Acid 8.0% c) .Soluble Potash 8.0% With at least fifty (50) percent of the nitrogen from a non -water soluble organic source. The following measures shall be incorporated during fertilization: Apply fertilizer at a rate of 1000 lbs./acre. Apply after smooth raking of topsoil. Do not apply fertilizer at same time or with same machine as will be used to apply seed. Till fertilizer into upper two (2) inches of topsoil. Lightly water dry topsoil to depth of six (6) inches at least forty-eight (48) hours prior to seeding to obtain a loose friable seed bed and to aid in the dissipation of fertilizer, The following rates and practices will be adhered to for all seeding that occurs on -site; Apply seed a rate of 6-lbs.11000 sq. ft, evenly at right angles with a spreader or seeding machine. Rake in lightly, covering seed to depth of 118 inch. Do not seed area in excess of that which can be mulched on same day, . Do not sow immediately following rain, when ground is too dry, or during windy periods. Roll seeded area with roller not exceeding 112 lbs. Immediately following seeding and compacting apply mulch to a thickness of one (1) —® THE COX COMPANY Planners -Landscape Architects Civil Engineers ® Urban Designers 220 East High Street Charlottesville e Virginia 22902.(434J 295.7131 Job Number. 04-60 Vineyard Estates, L,L,C. 100 Grand Cru Road Charlottesville, VA 22902 (434) 977 - 3895 Job Number: 04-60 . r,��\- -�H OF _71N, ,r,-,,,�\<-� - a FRANK D.
