Check to see if 95% turf cover or vegetation density has been achieved in the bed and banks of the dry swale. 2. Check for sediment buildup at curb cuts, gravel diaphragms or pavement edges that prevents flow from getting into the Bioretention swale, and check for other signs of bypassing. 3. Check for any winter- or salt -killed vegetation. 4. Check inflow points for clogging or accumulated sand, sediment, and trash, and remove it. 5. Inspect dry swale side slopes and grass filter strips for evidence of any rill or gully erosion, and repair it. 6. Check the bioretention Swale for evidence of excessive ponding or concentrated flows, and take appropriate remedial action. 7. When sediment accumulation is noted, look for any bare soil or sediment sources in the contributing drainage area, and stabilize them immediately. 8. Check for clogged or slow -draining soil media, a crust formed on the top layer, inappropriate so![ media, or other causes of insufficient filtering time, and restore proper filtration characteristics. 9. Inspect upstream and downstream of check dams for evidence of undercutting or erosion, and remove trash or blockages at weepholes.

The drawdown rate should be measured for three days following a storm event in excess of 1 /2 inch in depth. If standing water is still observed in the well after three days, this is a clear sign that clogging is a problem. 2. Check inlets for sediment buildup and structural damage. Note if any sediment needs to be removed. 3. Check that no vegetation forms an overhead canopy that may drop leaf litter, fruits, and other vegetative materials that could clog the infiltration device. 4.

A total of approximately 0.5 acres will be disturbed during construction. EXISTING SITE CONDITIONS The topographic and built improvements existing on the subject property are depicted on the accompanying E&S plan. The area of disturbance Is entirely comprised of an existing courtyard. The existing courtyard was in general accord with the original approved site plan (SDP 00-96.) ADJACENT AREAS Hickory Street forms the southern border to the site. Residential lots border the site to the north, south, east and west. The west border of the site is adjacent to Southwood Mobile Home Estates. The stream running through the site is a tributary to Biscuit Run. 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 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: Elioak Loam (27B), 2 to 7 percent slopes: This deep, gently sloping, well -drained soil is on broad to narrow convex ridge tops. Typically, the surface layer is dark brown and reddish brown loam about eight (8) inches thick. The subsoil is about 41 inches thick. It is yellowish red silty clay loam and red silty clay in the upper part and red silt clay loam and silt loam in the lower part. The substratum to a depth of 72 inches is mottled strong brown, yellowish red, and reddish brown silt loam. Permeability is moderate, and available water capacity is moderate.

The substratum to a depth of 30 inches or more and is strong brown channery loam. Permeability is moderately rapid and available water capacity is low. Surface runoff is rapid. The subsoil has low shrink -swell potential. Depth to bedrock is generally 20 to 40 inches. CRITICAL AREAS No critical areas are foreseen at this time. 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 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. 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. Temporary sediment filters and traps, perimeter dikes, sediment barriers and other measures intended to retain sediment shall be constructed as a first step in any land -disturbing activity and be made functional before up slope land disturbance takes place. Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions Immediately after installation. The following structural practices will be implemented according to the requirements set forth by the Virginia Erosion and Sediment Control. Safety Fence (3.01) A protective barrier consisting of polyethylene web secured to a conventional metal post driven into the ground a minimum of 18 inches. Posts should be spaced at 6-foot centers. Used to prevent undesirable use of an erosion control measure by the public. To prevent access to an erosion control measure. Specific Application: Safety fence will be used at areas where pedestrians may come into contact with the planned work. The Contractor shall consult with the Director of Facilities for the Covenant School prior to start of work for exact limits of safety fence throughout the project b).. Temporary Stone Construction Entrance (3.02) A seventy (70) foot stone section shall be installed at the point of vehicular ingress and egress on the construction site. This stone area shall be used for washing sediment from vehicles exiting the site. Where sediment is transported onto a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. Specific Application: A construction entrance shall be positioned to utilize the existing gravel access drive directly adjacent to the utility shed location. Additional gravel shall be applied if the Erosion Control inspector deems it necessary. If deemed necessary by the County Inspector the temporary stone construction entrance shall be converted Into a temporary paved construction entrance. Silt Fence (3.05) A temporary sediment barrier consisting of synthetic filter fabric stretched across and attached to supporting posts and entrenched Used to prevent sediment from leaving the site. To decrease the velocity of sheet flows. Specific Application: Silt fence shall be used as necessary or as directed by the Erosion Control inspector or where shown on the plan. 1.. Inlet Protection (3.07) A temporary sediment filter around a storm inlet or curb inlet, in order to prevent sediment from entering storm drainage systems prior to permanent stabilization of the disturbed area. Specific Application: Inlet protection will be used around all storm drainage inlets and curb inlets existing within the project area and as shown on the plan. 2L Temporary Seeding (3.31) The establishment of a temporary vegetative cover on disturbed areas by seeding with appropriate rapidly growing annual plants. This protects slopes exposed during construction until permanent vegetative cover can be established. Speck Application: Temporary seeding shall be used on all disturbed areas. D. 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. Speck Application: Permanent seeding will be applied to the disturbed areas. g). 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. 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; 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-241 C, 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-Ibs./l000 sq. ft. evenly at right angles with a spreader or seeding machine. Rake in lightly, covering seed to depth of 1/8 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 Ibs. Immediately following seeding and compacting apply mulch to a thickness of one (1) inch. Maintain clear of shrubs and trees. Apply water with a fine spray immediately after each area 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, Third Edition 1992. In general, all erosion and sediment control measures will be checked weekly and after each runoff -producing rainfall event. All seeded and sodded areas will be checked regularly to ensure that a good stand Is maintained. Areas will be fertilized, reseeded and resodded 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 The site is served by existing biofilters. Careful consideration shall be Implemented to ensure that siltation does not compromise these structures. A gravel diaphragm shall be utilized to pretreat new drainage flowing into the existing biofilter.
