The owner /developer must notify the County of Albemarle at least 24 hours prior to the start of construction in accordance with applicable county ordinances and policies. 2. The owner /developer grants the right —of —entry on to this property to the designated Albemarle County personnel for the purpose of inspecting and monitoring for compliance with title 10.01, Chapter 5, Article 4 of the Code of Virginia, Erosion and Sediment Control Law and the Design and Construction Standards Manual Section 750.04 (c). 3. All erosion control measures shown on the approved plan must be in place and inspected and approved by the County of Albemarle pnor to clearing, stripping of topsoil or grading. A copy of the approved erosion and sediment control plan and permit shall be kept on the site at all times. 4. The developer /developer's representative is responsible for the installation of any additional erosion control measures necessary to prevent erosion and sedimentation as determined by Albemarle County. 5. All disturbed areas are to drain to approved sediment control measures at al! times during land disturbing activities and during site development until complete and adequate stabilization is achieved. 6. Water must be pumped into an approved filtering device during dewatering operations. 7. All erosion and sediment control practices must be constructed and maintained according to the minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook and the Virginia Regulations VR 625 -02 -00 Erosion and Sediment Control Regulations. 8. The developer /developer's representative will be responsible for the installation and maintenance of all erosion and sediment control practices at all times. 9. The developerldeveloper's representative shall inspect all erosion and sediment control measures dally and after each significant rainfall. The following items will be checked in particular.• a. Sediment basins will be cleaned out when the level of sediment buildup reaches the cleanout elevation indicated on the riser pipe. Sediment shall be disposed in suitable areas and in such a manner that will not erode or cause sedimentation problems. The basin embankment should be checked regularly to ensure that it structurally sound and has not been damaged by erosion or construction equipment. Emergency spillways should be checked regularly to ensure that its lining is well established and erosion resistant. b. Sediment traps will be checked regularly for sediment cleanout. Sediment shall be removed and the trap restored to its original dimensions when the sediment has accumulated to one half the design volume of the wet storage. Sediment removed from the trap shall be deposited in a suitable area and in such a manner that it will not erode and cause sedimentation problems. c. Gravel outlets will be checked regularly for sediment buildup which will prevent drainage. If the gravel is clogged by sediment, it shall be removed and cleaned or replaced. d. Silt fence barriers will be checked regularly for undermining or deterioration of the fabric. Sediment shall be removed when the level of sediment deposition reaches half way to the top of the barrier. Seeded areas will be checked regularly to ensure that a good stand is maintained. Areas should be fertilized and reseeded as needed. e. Stream diversion and storm conveyance channels shall be inspected daily and after each rain to ensure they're functioning properly and that the integrity of the linings are not impaired. f. Any necessary repairs or cleanup to maintain the effectiveness of the erosion control devises must be made immediately after the inspection. 10. Sediment trapping measures will be installed as a first step in grading and will be seeded and mulched immediately following installation. 11. Permanent 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 undisturbed for longer than fourteen (14) days. Seeding and selection of the seed mixture shall be in accordance with the Virginia Erosion and Sediment Control Handbook Standard and Specification 3.32. Roads and parking areas shall be stabilized within seven (7) days after final grade is reached. 12. All temporary erosion and sediment control measures will be removed within 30 days after adequate site stabilization and after the temporary measures are no longer needed, as authorized by the Albemarle County inspectors. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures will be permanently stabilized to prevent further erosion and sedimentation. 13. When sediment is transported onto a paved road surface, the road will be cleaned thoroughly at the end of each day. Sediment will be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing will be allowed only after sediment is removed in this manner. 14.

EROSION AND SEDIMENT CONTROL NARRATIVE Charlottesville Self Storage Erosion and Sediment Control Plan The County of Albemarle, Virginia PROJECT DESCRIPTION The scope of this E &S narrative and plan is for the purpose of developing soil in preparation for the construction of additional storage buildings on site. A total of approximately 4.4 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, utility plan & profiles, and the general notes sheet. ADJACENT AREAS The northeastern edge of the property is bound by Moore's Creek. The northwestern edge is adjacent to Avon Street Extended. The southwestern edge is bound by a driveway adjacent to the City of Charlottesville's bus yard. The remaining southeastern edge is bordered by undeveloped land adjacent to Moore's Creek. The entire watershed for the project is tributary to Moore's Creek. 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 (12D): This moderately deep, moderately steep (15 -25 %) soil is well drained on side slopes. Usually, the surface layer is dark brown and dark yellowish brown silt loam about five (5) inches thick. The subsoil is strong brown, extremely channery silt loam containing pockets of reddish brown silty clay loam and is about thirteen (13) inches thick. The substratum below a depth of eighteen (18) inches is yellowish brown, extremely channery silt loam. Permeability is moderately rapid, and available water capacity is very low. Surface runoff is rapid. The hazard of erosion is severe. The subsoil has low shrink -swell potential. Depth to bedrock is twenty (20) to forty (40) inches. Udorthents, loamy (88): This map unit is made up of areas that have been used for cutting or filling during grading for road construction, housing developments, recreational areas, quarries, and other similar uses. The areas are generally irregular in shape, and conform to property boundaries. Slopes mainly range from 2 to 25 %. Permeability ranges from rapid to slow. Water capacity is generally moderate. Surface runoff and erosion range from moderate to rapid. Onsite investigations are required to determine the use and management of these soils CRITICAL AREAS There are several critical areas on the site. These are slopes created during previous phases of construction on the site and include all areas of proposed buildings. 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. a). Paved Wash Rack Construction Entrance (3.02) A seventy (70) foot paved section shall be installed at the point of vehicular ingress and egress on the construction site. This paved 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. This provision shall apply to individual subdivision lots as well as larger land disturbing activities. Specific Application: A construction entrance shall be placed adjacent to Redfields Road on the southern border of the property b). Construction Road Stabilization (3.03) Temporary stabilization with stone of access roads, subdivision streets, parking areas and other traffic areas immediately after grading to reduce erosion caused by vehicles during wet weather, and to prevent having to regrade permanent roadbeds between initial grading and final stabilization. Specific Application: Construction road stabilization shall be applied in areas which require stabilization after preliminary and fine grading. These areas include but may not be limited to the travelways. c). 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 will be used at the foot of the cut / fill slopes. d). 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. Temporary Diversion Dike (3.09) A temporary ridge of compacted soil constructed at the top or base of a sloping disturbed area. Used to divert sediment -laden runoff from a disturbed area to a stabilized outlet. Specific Application: Diversion Dikes will be used to divert runoff away from the disturbed areas of construction to the sediment traps. f). Temporary Sediment Trap (3.13) A temporary ponding area formed by constructing an earthen embankment with a stone outlet. It is used to detain sediment -laden runoff from drainage areas less than three acres for enough time to allow most of the sediment solids to settle out. It can be constructed only where there is sufficient space and appropriate topography. Maximum effective life is 18 months. Specific Application: Sediment traps will be used to detain runoff on the site at the foot of the fill and cut slopes. 2L Temporary Slope Drains (3.15) A flexible tubing or conduit extending from the top to the bottom of a cut or fill slope. The drains will temporarily conduct concentrated runoff safely down the face of a cut or fill slope without causing erosion on or below the slope. Speck Application: The drains shall be used to divert "clean" water from the high side of slopes affected by the construction of the proposed buidlings. Outlet protection shall be applied at the bottom of the drain. h). Outlet Protection (3.18) Structurally lined aprons or other acceptable energy dissipating devices placed at the outlets of pipes or paved channel sections. To prevent scour at stormwater outlets and minimize downstream erosion. Specific Application: This form of protection shall be performed on all stormwater outlets by using nprap. i). Surface Roughening (3.29) This erosion and sedimentation control measure involves creating horizontal depressions on slopes or leaving slopes in a roughened condition by not fine- grading them. This is done to aid in the establishment of vegetative cover or seed, to reduce runoff velocity and increase infiltration, and to reduce erosion and provide for sediment trapping. Specific Application: This form of protection shall be performed on all slopes 3:1 or greater as shown on the accompanying E &S Plan. Slopes less steep than 3:1 should have the soil lightly roughened and loose to a depth of 24" prior to seeding. D. 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. Temporary seeding will apply to all areas on the site that will not be brought to final grade for periods of thirty (30) days to one year. Selection of the appropriate seed mixture depends upon the time of year it is to be applied (See schedule on E &S details sheet.) 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. k). 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 distulrbed area. I) Mulching (3.35) it will prevent erosion b The application of plant residues to the so surface p e y protecting the soil surface from raindrop impact and reducing the velocity of overland flow. Mulch will foster the growth of vegetation by increasing available moisture and providing insulation against extreme heat and cold. Specific Application: Bark chips or shredded bark applied in conjunction with ornamentals for landscaping purposes. m). 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 proposed detention pipe outlets. 1. 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 if time requires. o). Diversion (3.12) A channel constructed across a slope with a supporting earthen ridge on the lower side. Used to reduce the slope length and to intercept and divert stormwater runoff to stabilized outlets at non - erosive velocities. Specific Application: Diversions will be used to direct "clean" water from the existing storm pipes off -site. p) Fill Diversion (see 3.09) A temporary ridge of compacted soil constructed at the top or base of a sloping disturbed area. Used to divert sediment -laden runoff from a disturbed area to a stabillized outlet. Specific Application: Diversion Dikes will be used to divert runoff away from the disturbed areas of construction /. 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 b) Phosphoric Acid C) Soluble Potash 8.0% 8.0% 12.0% 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 rasp, 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) 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 Iresodded 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 Where applicable, silt fence and seeding will be capable of separating suspended solids from the runoff before it enters the existing natural channels. The runoff from the drains will increase the velocity of the runoff from outflow devices, 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. The bio- retention basin will treat both the onsite as well as contributing stormwater passing through the site for quality. Since the project is adjacent to the 100 yr floodplain, a waiver will be applied for to treat the stormwater for quality only and not for quantity. cl - t7 -Cj� Ar 7® ® ®O THE COX COMPANY Planners • Landscape Architects Civil Engineers -Urban Designers 220 East High Street Charlottesville • Virginia 22902.1434) 295.7131 Job Number. 04 -10 Owner /Developer: VIRGINIA SELF STORAGE PARTNERS 1, I.I.C.
