ES -2: The plan approving authority must be notified one week prior to the pre -construction conference, one week prior to the commencement of land disturbing activity, and one week prior to the final inspection. ES -3: All erosion and sediment control measures are to be placed prior to or as the first step in clearing. ES -4: A copy of the approved erosion and sediment control plan shall be maintained on the site at all times. ES -5: Prior to commencing land disturbing activities in areas other than indicated on these plans (including but not limited to, off-site borrow or waste areas). The contractor shall submit a supplementary erosion control plan to the owner for review and approval by the plan approving authority. ES -6: The contractor is responsible for installation of any additional erosion control measures necessary to prevent erosion and sedimentation as determined by the plan approving au th ori ty. ES -7.• All disturbed areas are to drain to approved sediment control measures at all times during land disturbing activities and during site development until final stabilization is achieved. ES -8: During dewatering operations, water will be pumped into an approved water filtering device. ES -9: The contractor shall inspect erosion control measures periodically and after each run-off producing rainfall event. Any necessary repairs or cleanup to maintain the effectiveness of the erosion control devices shall be made immediately. EROSION AND SEDIMENT CONTROL MEASURES gL 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 of 6 -foot centers. Used to prevent undesirable use of an erosion control measure by the public. To prevent access to an erosion control measure. li n: Safety fence will be used around a/1 sediment traps and basins. (, 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. ecific Application: A construction entrance shall be placed at the end of existing Boulders Drive. Silt Fence 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 &i2lication: Silt fence will be used at the foot of the cut / fill slopes. rRGEND �k VIRGINIA EROSION & SEDIMENT CONTROL 0 34D 27B 213 ALBMARLE COUNTY CONSTRUCTION ENTRANCE sesrac swKc otRacrs aosr �o taatentr a►/al 7CMCV. -- �• �-r sr -2A AVW i4P GOWN 22 w Aa / onlER�or1 on�H� SIDE ELEVATION EXSW40 OR"D -7 a 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. 5Recif/c A0li n: Inlet protection will be used around all storm drainage inlets and curb inlets. a), Temporary Diversion Dike (3.09) A temporary ridge of compacted soil constructed at the top or base of a sloping disturbed area.

SDecifiC AA tion: Diversion Dikes will be used to divert runoff away from the disturbed areas of construction. & 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. SDecif<c A,2121/cation : This form of protection shall be performed on all stormwater outlets by using riprop. g), Temporary Seeding(3 31)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 a// 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.) S2eciflc Application: Temporary seeding shall be applied to all denuded areas prior to permanent stabilization in the form of either horoscope or permanent seeding. Temporary seeding shall be used on all fill slopes and diversions. 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. ecific ApQlicotion: Permanent seeding will be applied to all portions of disturbed area. Dust Control X3.39) 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.

After these areas are stabilized, they will be mowed and maintained on a regular basis. MAIWEINANCE In general, all erosion and sediment control measures will be checked daily and after each significant rainfall. Specific attention will be given to the following items: A. Sediment basins and/or traps will be cleaned and maintained in accordance with the Virginia Erosion & Sediment Control Handbook. Sediment traps will be checked regularly for sediment cleanout. B. All gravel outlets will be checked regularly for sediment buildup that will prevent proper drainage. If the gravel is clogged by sediment, the gravel will be removed and cleaned, or it will be replaced. C. All silt fence barriers will be checked regularly for undermining or deterioration of the fabric and repaired as required. Sediment shall be removed when the level of sediment deposition reached half way to the trop of the barrier. D. All seeded areas will be checked regularly to see that o 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 bosins, shall be removed within 30 days after final site stabilization is achieved or after the temporary measures are no longer needed, unless otheriwise 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 stormwater and runoff from the site will be captured and carried in a permanent stormwater management pond located con site. This pond is sized for water quality and water quantity. This pond shall remain permanent and operational until such time that the expansion below is complete.
