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 to larger land -disturbing activities. 18. All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or after the temporary measures are no longer needed, H unless otherwise authorized by the VESCP authority. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. 19. Properties and waterways downstream from development sites shall be protected from sediment deposition, erosion and damage due to increases in volume, velocity and peak flow rate of stormwater runoff for the stated frequency storm of 24-hour duration in accordance with the following standards and criteria. Stream restoration and relocation projects that incorporate natural channel design concepts are not man-made channels and shall be exempt from any flow rate capacity and velocity requirements for natural or man-made channels: a. Concentrated stormwater runoff leaving a development site shall be discharged directly into an adequate natural or man-made receiving channel, pipe or storm sewer G system. for those sites where runoff is discharged into a pipe or pipe system, downstream stability analyses at the outfall of the pipe or pipe system shall be performed. b.

If existing natural receiving channels or previously constructed man-made channels or pipes are not adequate, the applicant shall: 1.1. Improve the channel to a condition where a ten-year storm will not overtop the banks and a two-year storm will not cause erosion to the channel bed or banks; or 1.2. Improve the pipe or pipe system to a condition where the ten-year storm is contained with the appurtenances; or 1.3. Develop a site design that will not cause the pre -development peak runoff rate from a two-year storm to increase when runoff outfalls into a natural channel or will not cause the development peak runoff rate from a ten-year storm to increase when runoff outfalls into a man-made channel; or 1.4. Provide a combination of channel improvement, stormwater detention or other measures which is satisfactory to the VESCP authority to prevent downstream E erosion. d. The applicant shall provide evidence of permission to make the improvements. e. All hydrologic analysts shall be based on the existing watershed characteristics and the ultimate development of the subject project. f. If the applicant chooses an option that includes stormwater detention he shall obtain approval from the VESCP of a plan for maintenance of the detention facilities. the plan shall set forth the maintenance requirements of the facility and the person responsible for performing the maintenance. D g. Outfall from a detention facility shall be discharged to a receiving channel, and energy dissipators shall be placed at the outfall of all detention facilities as necessary to provide a stabilized transition from the facility to the receiving channel. h. All on -site channels must be verified to be adequate. i. Increased volumes of sheet flows that may cause erosion or sedimentation on adjacent property shall be diverted to a stable outlet, adequate channel, pipe or pipe system, or to a detention facility. j.

Necessary grading, erosion control, & SWM will be performed. The total subject property area is 7.757 acres. The total area of disturbance is 5.50 acres. EXISTING SITE CONDITIONS: Currently the site topography consists of a hill with a ridge running through the middle conveying site drainage to a concrete ditch north of the property and a culvert running underneath Old Lynchburg Rd to the south of the property. Existing slopes range from 5% to 50%. Existing ground cover consists of short grass, brush, and dense trees. ADJACENT AREAS: The adjacent property to the southwest is an existing residential town home development.The parcel is bordered to the north by an area of dense mature trees (separating it from Interstate 64) and to the east by Old Lynchburg Rd.. OFF -SITE AREAS: The proposed site grading will require exporting of excess soils to attain final grades. Before a Land Disturbance Permit is issued by the County, the contractor shall provide documentation of an approved ESC offsite area for required excess soil removal. This offsite area must be added to the SWPPP once identified. 5. SOILS: See Sheet C2 and any supplemental soil reports for site specific soils data. 6. CRITICAL AREAS: Critical areas are any slopes steeper than 25% as shown on Sheet C2. Preserved steep slope areas are to not be disturbed and protected with tree preservation & protection. 7. EROSION AND SEDIMENT CONTROL MEASURES: Unless otherwise indicated, all vegetative and structural erosion and sediment control practices shall be constructed and maintained according to minimum standards and specifications of the Virginia Erosion & Sediment Control Handbook (VESCH). The minimum standards of the VESCH shall be adhered to unless otherwise waived or approved by a variance. The following measures are proposed: 3.02 - Temporary Construction Entrance A stone pad, located at points of vehicular ingress and egress on a construction site, to reduce the soil transported onto public roads and other paved areas. Temporary construction entrance(s) shall be installed as indicated on the plans. 0 9 3.05 - Silt Fence Barrier Silt fence sediment barriers will be installed down -slope of disturbed areas to filter sediment -laden runoff from sheet flow as indicated on this sheet. 3.07 - Storm Drain Inlet Protection To prevent sediment from entering storm drainage systems prior to permanent stabilization of the disturbed area. 3.09 - Temporary Diversion Dike Used to divert off -site runoff from disturbed areas, or to divert sediment -laden runoff to a sediment trapping structure. 3.11 - Temporary Right -of -Way Diversion A ridge of loose gravel to divert run-off across a disturbed area to a stabilized outlet where vehicular traffic must be accommodated. 3.12 - Diversion A permanent channel with a ridge on the lower side constructed across a slope to reduce slope length and intercept and divert stormwater runoff to a stabilized outlet at non -erosive velocities. 3.13 - Temporary Sediment Trap Temporary sediment trap(s) shall be constructed before land disturbance as indicated on the plans. 3.17 - Stormwater Conveyance Channel A permanent channel designed to carry concentrated flows without erosion.

Sept. 1 - Feb. 15 50/50 mix annual ryegrass & winter rye 50-100 Feb. 16 - Apr. 30 annual ryegrass 60-100 May 1 - Aug. 31 german millet 50 Note: Alternate seeding per VESCH, Table 3.31-C. 3.33 - Sodding Stabilizing fine -graded disturbed areas by establishing permanent grass stands with sod. 3.35 - Mulching Application of plant residues or other suitable material to disturbed areas to prevent erosion and reduce overland flow velocities. Fosters plant growth and provides insulation from heat and cold Applied to seeded areas or disturbed areas that cannot be seeded due to the season. 3.38 - Tree Preservation & Protection Protection of desirable trees from mechanical and other injury during land disturbing and construction activity. 3.39 - Dust Control Application of water or other agent to traffic areas to reduce surface and air movement of dust during land disturbing or construction activities to prevent soil loss and reduce the airborne substances PERMANENT STABILIZATION: All areas disturbed by construction shall be stabilized with permanent seeding and/or sodding immediately following finish grading in accordance with the plans. Seeding shall be done according to VESCH Standards & Specifications 3.32. Erosion control blankets will be installed over fill slopes 2HAV or steeper which have been brought to final grade and have been seeded to protect the slopes from rill and gully erosion and to allow seed to germinate properly. Cut slopes of 3H:1 V or steeper shall have surface roughening performed according to VESCH Standards & Specifications 3.29, Surface Roughening. Mulch (straw or fiber) will be used on relatively flat areas. In all seeding operations, seed, fertilizer and lime (if required per soils report) will be applied prior to mulching. STORMWATER MANAGEMENT: Stormwater management measures for run-off quantity and quality are addressed by bioretention and underground SWM detention pipes. Calculations for the capacity of the stormwater drainage structures and pipes proposed within these site plans are provided. (Refer to 'Engineering Report' dated 03-13-2017) 10. MAINTENANCE: 3.02 - Temporary Construction Entrance The entrance shall be maintained in a condition which will prevent tracking or flow of mud onto public rights -of -way. This may require periodic top dressing with additional stone or the washing and reworking of existing stone as conditions demand and repair and/or cleanout of any structures used to trap sediment. All materials spilled, dropped, washed or traced from vehicles onto roadways or into storm drains must be removed immediately. The use of water trucks to remove materials dropped, washed, or tracked onto roadways will not be permitted under any circumstances. 3.05 - Silt Fence Barrier a. Silt fences shall be inspected immediately after each rainfall and at least daily during prolonged rainfall. Any required repairs shall be made immediately. b. Close attention shall be paid to the repair of damaged silt fence resulting from end runs and undercutting. c. Should the fabric on a silt fence decompose or become ineffective prior to the end of the expected usable life and the barrier still be necessary, the fabric shall be replaced promptly. d. Sediment deposits should be removed after each storm event. They must be removed when deposits reach approximately one-half the height of the barrier. 3.07 - Storm Drain Inlet Protection a. The structure shall be inspected after each rain and repairs made as needed. b. Sediment shall be removed and the trap restored to its original dimensions when the sediment has accumulated to one half the design depth of the trap. Removed sediment shall be deposited in a suitable area and in such a manner that it will not erode. c. Structures shall be removed and the area stabilized when the remaining drainage area has been properly stabilized. 3.09 - Temporary Diversion Dike The measure shall be inspected after every storm and repairs made to the dike, flow channel, outlet or sediment trapping facility, as necessary. Once every two weeks, whether a storm event has occurred or not, the measure shall be inspected and repairs made if needed. Damages caused by construction traffic or other activity must be repaired before the end of each working day. 3.11 - Temporary Right -of -Way Diversion The practice shall be inspected after every rainfall and repairs made if necessary. At least once every two weeks, whether a storm has occurred or not, the measure shall be inspected and repairs made if needed. Right-of-way diversions, which are subject to damage by vehicular traffic, should be reshaped at the end of each working day. 3.12 - Diversion Before final stabilization, the diversion should be inspected after every rainfall and at least once every two weeks. Sediment shall be removed from the channel and repairs made as necessary. Seeded areas which fail to establish a vegetative cover shall be reseeded as necessary. 3.13 - Temporary Sediment Trap a. Sediment shall be removed and the trap restored to it original dimensions when the sediment has accumulated to one half the design volume of the wet storage. Sediment removal from the basin shall be deposited in a suitable area and in such a manger that it will not erode and cause sedimentation problems. b. Filter stone shall be regularly checked to ensure that filtration performance is maintained. Stone choked with sediment shall be removed and cleaned or replaced. c. The structure should be checked regularly to ensure that it is structurally sound and has not been damaged by erosion or construction equipment. The height of the stone outlet should be checked to ensure that its center is at least 1' below the top of the embankment. 3.17 - Stormwater Conveyance Channel Concrete -lined Channels Concrete -lined channels should be checked periodically to ensure that there is no undermining of the channel. Particular attention should be paid to the outlet of the channel. If scour is occurring at the outlet, appropriate outlet protection shall be installed. See OUTLET PROTECTION, Std. & Spec. 3.18 3.18 - Outlet Protection a. Inspect after each significant rain for erosion and/or disruption of the rock, and repair immediately. b. Grouted or wire -tied rock riprap can minimize maintenance requirements. 3.19 - Riprap Once a riprap installation has been completed, it should require very little maintenance. It should, however, be inspected periodically to determine if high flows have caused scour beneath the riprap or filter fabric or dislodged any of the stone. Care must be taken to properly control sediment -laden construction runoff which may drain to the point of the new installation. If repairs are needed, they should be accomplished immediately. 3.33 - Sodding a. During the 2 to 3 week establishment stage, sod shall be watered as necessary to maintain adequate moisture in the root zone and prevent dormancy of sod. b. No more than one third of the shoot (grass leaf) should be removed in any mowing. Grass height should be maintained between 2 and 3 inches unless otherwise specified. c. After the first growing season, established sod will require fertilization and may require lime. Follow soil test recommendations when possible, or apply maintenance levels as outlined in Table 3.33-B. 3.35 - Mulching All mulches and soil coverings should be inspected periodically (particularly after rainstorms) to check for erosion. Where erosion is observed in mulched areas, additional mulch should be applied. Nets and mats should be inspected after rainstorms for dislocation or failure. If washouts or breakage occur, re -install netting or matting as necessary after repairing damage to the slope or ditch. Inspections should take place up until grasses are firmly established. Where mulch is used in conjunction with ornamental plantings, inspect periodically throughout the year to determine if mulch is maintaining coverage of the soil surface; repair as needed. Application rate = 2 tons per acre. All mulching shall be anchored in place. 11. MANAGEMENT STRATEGIES A. Construction will be sequenced so that grading operations can begin and end as quickly as possible. B. Sediment trapping measures will be installed as a first step in grading and will be seeded and mulched immediately following installation. C. Temporary seeding or other stabilization will follow immediately after grading. Stabilization for all critical areas will consist of EC-2 lining. D. Areas which are not to be disturbed will be clearly marked by flags, signs, etc. E. The job superintendent shall be responsible for the installation and maintenance of all erosion and sediment control practices. F. After achieving adequate stabilization, the temporary erosion controls will be cleaned up and removed. 12. GENERAL NOTES: A.

Inspect bi-annually and after each storm event the contributing drainage areas, Bioretention facility, J inlets, outlets, underdrains, overflows and cleanouts for debris, sediment, proper drainage and damages. Clean and dispose of all debris, trash and sediment properly. Should structural damages be encountered contact design engineer for replacement information and notify the County of Augusta Engineer of the damages and proposed repair procedures. 2. The observation well shall be checked quarterly and after each large storm event. A log book shall be maintained showing the depth of water in the well during each inspection in order to determine the rate at which the facility dewaters after runoff producing storm events. Once the performance characteristics of the structure have been verified, the monitoring schedule can be reduced to an annual basis, unless the performance data suggests that a more frequent schedule is required. At the end of the first year the Landowner shall provide a copy of the log book and the revised monitoring schedule to the county engineering department to be reviewed by the Erosion and Sediment control inspector. The inspector will approve the revised monitoring schedule or require further inspections that shall be carried out by the Landowner. 3. Inspect plant material bi-annually. Address any problems found due to disease or insect infestations. Diseased plants must be treated by a qualified professional. Replace any dead plant material and prune as necessary. Consult a landscape architect or horticulturist for specific pruning measures. All replacement plants shall meet original design specifications. New plants shall be watered everyday for H the first 14 days after planting. 4. Conduct organic layer and soil tests twice a year to maintain proper pH. An application of alkaline, such as limestone, shall be applied as needed per test results. 5. The soil mix shall be tested annually to check for the presence of toxins and heavy metals. If levels are high and the plant biologic functions are impaired (dwarfed growth and mortality) the contaminated soil and any dead plants shall be removed and replaced. All removed material shall be disposed of properly. In some cases, the removal and disposal of the entire soil base as well as the plant material may be required. Replacement soil mix and plants shall meet original design specifications. 6. Inspect mulch layer for voids and to ensure specified thickness. Replacement of mulch layer is required G every two to three years. Mulch shall be replaced in spring. The previous layer shall be removed first. 7. When sand or other street abrasives are used on areas draining to bioretention basin during snow and icing conditions the pavement shall be power/vacuum swept as soon as freezing weather abates to prevent damage to the basins. 8. Inspect bi-annually all inlets structures, manholes, storm pipes, cleanouts and roof drains for proper drainage and structural integrity. Should damages be encountered contact design engineer for replacement information and notify County Engineering department of damages and repair procedures. 9. Inspect bi-annually all inlets structures, manholes, storm pipes, cleanouts and roof drains for debris and sediment. Clean and dispose of all debris, trash and sediment properly.

Caution needs to be taken while inspecting the Stormwater D Management (SWM) facility; there is a hazard of soft saturated sediment and soil. 2. The SWM facility shall be checked for sediment build-up. If sediment build up reaches the cleanout level, the sediment shall be removed and disposed of properly. 3. The SWM embankment shall be checked to ensure it is structurally sound, has not been damaged by erosion, and has no trees or other deep rooting plants growing on it. If damage appears to be evident contact C an engineer to inspect. 4. The emergency weir shall be checked to ensure its lining is well established and erosion -resistant. If the emergency weir is no longer established the weir shall be relined. If it is no longer erosion -resistant the weir shall be relined. 5. The riser structure shall be checked to ensure it is structurally sound, has not endured any damage and does not have excess sediment build up. If the structure is found to be structurally unsound the entire structure shall be replaced. If the structure is damaged repairs shall be B made immediately. If there is an excess of sediment in the riser structure the sediment shall be removed and disposed of properly. 6. The culvert, leading from the riser structure and running underneath the SWM embankment, shall be checked regularly to ensure it has not endured any damage, is not being undermined, and does not have excess sediment build up. If the structure has any damage the damage shall be repaired immediately. If the structure is being undermined by water an engineering investigation will need to be preformed on the embankment. If an excess of sediment is present, the sediment shall be A removed and disposed of properly.
