THE MINIMUM STORAGE CAPACITY OF A SEDIMENT TRAP SHALL BE 134 CUBIC YARDS PER ACRE OF DRAINAGE AREA AND THE TRAP SHALL ONLY CONTROL DRAINAGE AREAS LESS THAN THREE ACRES. B. SURFACE RUNOFF FROM DISTURBED AREAS THAT IS COMPRISED OF FLOW FROM DRAINAGE AREAS GREATER THAN OR EQUAL TO THREE ACRES SHALL BE CONTROLLED BY A SEDIMENT BASIN. THE MINIMUM STORAGE CAPACITY OF A SEDIMENT BASIN SHALL BE 134 CUBIC YARDS PER ACRE OF DRAINAGE AREA. THE OUTFALL SYSTEM SHALL, AT A MINIMUM, MAINTAIN THE STRUCTURAL INTEGRITY OF THE BASIN DURING A 25-YEAR STORM OF 24-HOUR DURATION. RUNOFF COEFFICIENTS USED IN RUNOFF CALCULATIONS SHALL CORRESPOND TO A BARE EARTH CONDITION OR THOSE CONDITIONS EXPECTED TO EXIST WHILE THE SEDIMENT BASIN IS UTILIZED. MS-7. 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 STABILIZING MEASURES UNTIL THE PROBLEM IS CORRECTED. MS-8. CONCENTRATED RUNOFF SHALL NOT FLOW DOWN CUT OR FILL SLOPES UNLESS CONTAINED WITHIN AN ADEQUATE TEMPORARY OR PERMANENT CHANNEL, FLUME OR SLOPE DRAIN STRUCTURE. MS-9. WHENEVER WATER SEEPS FROM A SLOPE FACE, ADEQUATE DRAINAGE OR OTHER PROTECTION SHALL BE PROVIDED. MS-10. ALL STORM SEWER INLETS THAT ARE MADE OPERABLE DURING CONSTRUCTION SHALL BE PROTECTED SO THAT SEDIMENT -LADEN WATER CANNOT ENTER THE CONVEYANCE SYSTEM WITHOUT FIRST BEING FILTERED OR OTHERWISE TREATED TO REMOVE SEDIMENT.

F. APPLICABLE SAFETY REQUIREMENTS SHALL BE COMPLIED WITH. MS-1 7. WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED OR PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PAVED OR PUBLIC ROAD SURFACE, THE ROAD SURFACE 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 DEVELOPMENT LOTS AS WELL AS TO LARGER LAND -DISTURBING ACTIVITIES. MS-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, 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. MS-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.

ADEQUACY OF ALL CHANNELS AND PIPES SHALL BE VERIFIED IN THE FOLLOWING MANNER: (1) THE APPLICANT SHALL DEMONSTRATE THAT THE TOTAL DRAINAGE AREA TO THE POINT OF ANALYSIS WITHIN THE CHANNEL IS ONE HUNDRED TIMES GREATER THAN THE CONTRIBUTING DRAINAGE AREA OF THE PROJECT IN QUESTION; OR (2) (A) NATURAL CHANNELS SHALL BE ANALYZED BY THE USE OF A TWO-YEAR STORM TO VERIFY THAT STORMWATER WILL NOT OVERTOP CHANNEL BANKS NOR CAUSE EROSION OF CHANNEL BED OR BANKS. (B) ALL PREVIOUSLY CONSTRUCTED MAN-MADE CHANNELS SHALL BE ANALYZED BY THE USE OF A TEN-YEAR STORM TO VERIFY THAT STORMWATER WILL NOT OVERTOP ITS BANKS AND BY THE USE OF A TWO-YEAR STORM TO DEMONSTRATE THAT STORMWATER WILL NOT CAUSE EROSION OF CHANNEL BED OR BANKS; AND (C) PIPES AND STORM SEWER SYSTEMS SHALL BE ANALYZED BY THE USE OF A TEN-YEAR STORM TO VERIFY THAT STORMWATER WILL BE CONTAINED WITHIN THE PIPE OR SYSTEM. C. IF EXISTING NATURAL RECEIVING CHANNELS OR PREVIOUSLY CONSTRUCTED MAN-MADE CHANNELS OR PIPES ARE NOT ADEQUATE, THE APPLICANT SHALL: (1) IMPROVE THE CHANNELS 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, THE BED, OR THE BANKS; OR (2) IMPROVE THE PIPE OR PIPE SYSTEM TO A CONDITION WHERE THE TEN-YEAR STORM IS CONTAINED WITHIN THE APPURTENANCES; (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 PRE -DEVELOPMENT PEAK RUNOFF RATE FROM A TEN-YEAR STORM TO INCREASE WHEN RUNOFF OUTFALLS INTO A MAN-MADE CHANNEL; OR (4) PROVIDE A COMBINATION OF CHANNEL IMPROVEMENT, STORMWATER DETENTION OR OTHER MEASURES WHICH IS SATISFACTORY TO THE VESCP AUTHORITY TO PREVENT DOWNSTREAM EROSION. D. THE APPLICANT SHALL PROVIDE EVIDENCE OF PERMISSION TO MAKE THE IMPROVEMENTS. E. ALL HYDROLOGIC ANALYSES SHALL BE BASED ON THE EXISTING WATERSHED CHARACTERISTICS AND THE ULTIMATE DEVELOPMENT CONDITION 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 PROJECT ALSO PROPOSES A BIORETENTION BASIN TO MEET STORMWATER MANAGEMENT REQUIREMENTS. THE PROJECT WILL HAVE A TOTAL DISTURBED AREA OF APPROXIMATELY 1.75 ACRES. WITHIN THE LIMITS OF DISTURBANCE, THERE ARE 0.01 ACRES CLASSIFIED AS IMPERVIOUS AREA, 0.18 ACRES CLASSIFIED AS MANAGED TURF, AND 1.56 ACRES CLASSIFIED AS FORESTED AREA IN THE EXISTING CONDITIONS. IN THE PROPOSED CONDITIONS, THERE ARE 0.80 ACRES CLASSIFIED AS MANAGED TURF AND 0.95 ACRES CLASSIFIED AS IMPERVIOUS AREA. IN ADDITION, 4.50 ACRES OF FORESTED AREA ON THE PROPERTY OUTSIDE THE LIMITS OF DISTURBANCE WILL BE PLACED IN A PERMANENT EASEMENT FOR PROTECTION. 1.2 EXISTING SITE CONDITIONS THE SITE IS LOCATED IN SOUTHERN ALBEMARLE COUNTY ON ESMONT ROAD. THE PROPERTY IS LOCATED SOUTH OF THE TOWN OF KEENE, WEST OF SCOTTSVILLE ROAD (ROUTE 20), AND EAST OF ESMONT ROAD. IN THE EXISTING CONDITIONS, THE PROPERTY IS MOSTLY FORESTED WITH A GRAVEUDIRT ROAD UNDER THE POWER LINES ACROSS THE FRONT TO THE SITE. A DIRT DRIVE EXTENDS TO THE EAST THROUGH THE MIDDLE OF THE SITE. THERE IS A HIGH POINT THROUGH THE MIDDLE OF THE SITE, FORCING THE RUNOFF FLOW EITHER TO THE NORTH OR SOUTH. THE EXISTING TOPOGRAPHY ON THE WEST END OF THE SITE RANGES FROM 1 % TO 8% WITH SLOPES GRADUALLY BECOMING STEEPER AS YOU MOVE AWAY FROM THE RIDGE RUNNING WEST TO EAST TO APPROXIMATELY 8% TO 16% SLOPES. 11.3ADJACENT PROPERTY THE PROPOSED SITE IS LOCATED IN SOUTHERN ALBEMARLE COUNTY. THE PROPERTIES BOARDING THE SITE ARE ALL CLASSIFIED AS RURAL AREAS. THE PROPERTY TO THE NORTH IS HEAVILY FORESTED WHILE THE PROPERTIES TO THE EAST AND SOUTH ARE A MIX OF FORESTED AND OPEN SPACE. THE SITE IS LOCATED APPROXIMATELY 800 FEET FROM THE INTERSECTION OF ESMONT ROAD AND SCOTTSVILLE ROAD. NO DISTURBANCE WILL TAKE PLACE ON ADJACENT PROPERTY. WITH PROPER SEDIMENT CONTROL IN PLACE TO CONTAIN SEDIMENT BEFORE LEAVING THE LIMITS OF CONSTRUCTION, NO ADVERSE EFFECTS RESULTING FROM SEDIMENT DEPOSITION IS ANTICIPATED FOR ANY OF THE ADJACENT OR DOWNSTREAM AREAS. 1.4 PLANNED OFF SITE ACTIVITIES THE PROJECT IS ANTICIPATED TO REQUIRE THE IMPORT OF FILL MATERIAL. ALL IMPORTED MATERIAL REQUIRED FOR BACKFILL, ETC., SHALL BE OBTAINED FROM A PREVIOUSLY PERMITTED OFF -SITE AREA OR A COMMERCIAL FACILITY. ALL EXCESS OR UNSUITABLE MATERIAL SHALL BE TRANSPORTED TO A PREVIOUSLY PERMITTED OFF -SITE DISPOSAL AREA. SHOULD ADDITIONAL OFF -SITE AREAS BE REQUIRED WHICH DO NOT HAVE AN EXISTING PERMIT, THEY SHALL HAVE SEPARATE EROSION AND SEDIMENT CONTROL PLANS APPROVED BY THE AUTHORITY HAVING JURISDICTION. THE NAMES OF ANY OFFSITE AREAS MUST BE PROVIDED TO ALBEMARLE COUNTY BEFORE ANY SOIL IS TRANSPORTED OFFSITE. THE CONTRACTOR SHALL BE RESPONSIBLE FOR IMPLEMENTING THE APPROVED EROSION AND SEDIMENT CONTROL PLAN ALONG WITH FINAL STABILIZATION AND MAINTENANCE OF ALL OFF -SITE AREAS. 1.5 SOILS A NATURAL RESOURCE CONSERVATION SERVICE (NRCS) CUSTOM SOIL RESOURCE REPORT FOR ALBEMARLE COUNTY, VIRGINIA DATED NOVEMBER 30, 2021 SHOWS THAT THE MAJORITY OF THE SOILS ON SITE ARE CLASSIFIED AS BUFFSTAT SILT LOAM WITH A HYDROLOGIC SOIL GROUP CLASSIFICATION OF B. A SMALL PORTION OF THE SOILS ON THE NORTHEAST AND SOUTHWEST SIDES OF THE SITE HAVE SOILS CLASSIFIED AS BUGLEY CHANNERY SILT LOAM WITH A HYDRAULIC SOIL GROUP CLASSIFICATION OF D. REFER TO APPENDIX C-1 FOR THE FULL SOIL REPORT. A FULL GEOTECHNICAL REPORT WAS ALSO COMPLETED FOR THE PROJECT AND WILL BE MADE AVAILABLE FOR THE CONTRACTOR'S USE 1.6 CRITICAL EROSION AREAS THE PROJECT WILL HAVE PROPOSED TIE IN SLOPES OF 3:1 THAT COULD BE CONSIDERED CRITICAL EROSION AREAS. REGULAR INSPECTIONS SHALL BE CONDUCTED ACROSS THE ENTIRE SITE TO ENSURE THE DISTURBED AND DOWNSTREAM SOILS DO NOT BECOME EROSIVE AS CONSTRUCTION PROGRESSES. IN GENERAL, THE CONTRACTOR SHALL MINIMIZE THE AREAS DISTURBED AT ONE TIME AND SHALL IMMEDIATELY APPLY SEED AND MULCH TO DENUDED AREAS AFTER WORK IS PERFORMED. 1.7 EROSION AND SEDIMENT CONTROL MEASURES UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO THE LATEST STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK.

TEMPORARY CONSTRUCTION ENTRANCE - 3.02 A STONE PAD, LOCATED AT THE POINT OF VEHICULAR INGRESS AND EGRESS TO THE CONSTRUCTION SITE. THE PURPOSE IS TO PREVENT OR REDUCE THE AMOUNT OF MUD TRANSPORTED TO THE PUBLIC ROAD. SEDIMENT DISLODGED OR WASHED FROM THE VEHICLE SHOULD BE CONTAINED WITHIN A PROPER SEDIMENT TRAPPING AREA. ALL VEHICLES ENTERING AND EXITING A DISTURBED AREA SHALL USE THE ENTRANCE. THE LOCATION OF THE ENTRANCE MAY NEED TO BE RELOCATED AS CONSTRUCTION PROGRESSES; COORDINATE LOCATIONS WITH INSPECTORS. 2. SILT FENCE - 3.05 SILT FENCE SEDIMENT BARRIERS WILL BE INSTALLED DOWN SLOPE OF DISTURBED AREAS TO FILTER SEDIMENT LADEN RUNOFF. 3. TEMPORARY DIVERSION DIKE - 3.09 TO BE INSTALLED TO DIVERT STORMWATER RUNOFF TO TRAPPING MEASURES BY CREATING A TEMPORARY RIDGE OF COMPACTED SOIL CONSTRUCTED AT THE TOP OR BASE OF A SLOPING DISTURBED AREA. THE LOCATION OF THE DIVERSIONS MAY NEED TO BE ALTERED THROUGHOUT CONSTRUCTION TO ENSURE THE MAXIMUM AMOUNT OF RUNOFF FROM THE DISTURBED AREA IS BEING CAPTURED BY A TRAPPING MEASURE. 4. TEMPORARY SEDIMENT TRAP - 3.13 TO BE USED WHEN THE DRAINAGE AREA IS LESS THAT THREE ACRES TO DETAIN SEDIMENT -LADEN RUNOFF FROM SMALL, DISTURBED AREAS LONG ENOUGH TO ALLOW SEDIMENT TO FILTER OUT OF THE RUNOFF. 4. CHECK DAMS - 3.20 SMALL TEMPORARY STONE DAMS CONSTRUCTED ACROSS DRAINAGE CHANNELS TO REDUCE VELOCITY OF CONCENTRATED FLOWS, AND THEREBY REDUCING EROSION OF THE CHANNEL. 5. SURFACE ROUGHENING - 3.29 APPLIED ON GRADED SLOPES TO AID IN ESTABLISHING VEGETATION, REDUCE RUNOFF VELOCITY AND EROSION, AND PROVIDE FOR SEDIMENT TRAPPING. A ROUGH SOIL IS CREATED BY CREATING HORIZONTAL DEPRESSIONS BY RUNNING A TRACKED PIECE OF EQUIPMENT UP AND DOWN THE SLOPES. 6. TREE PROTECTION - 3.38 A TEMPORARY FENCE INSTALLED AROUND TREES AND VEGETATION THAT WILL REMAIN TO PREVENT DAMAGE DURING CONSTRUCTION. THE FENCING WILL BE INSTALLED ALONG THE DRIP LINE OF THE TREE WHERE POSSIBLE. 7.
