PROJECT DESCRIPTION THE PROJECT INCLUDES THE RELOCATION APPROXIMATELY 5,350 LINEAR FEET OF DRIVEWAYS TO SERVICE THE RESIDENCE AND ASSOCIATED BUILDINGS AT 1575 INGLERIDGE FARM, LOCATED IN ALBEMARLE COUNTY, VIRGINIA. CONSTRUCTION WILL INCLUDE DEMOLITION OF THE EXISTING GRAVEL ROADWAY AND REPLACING IT WITH A COMBINATION OF PAVED AND GRAVEL DRIVEWAYS, AN ADDITION TO THE EXISTING RESIDENCE AT THE NORTHERN END OF THE PROPERTY, THE CONSTRUCTION OF A POOL AND POOL HOUSE, AND MASS GRADING OF THE SITE TO RETURN THE TERRAIN BACK TO A MORE NATURAL STATE. THE DRIVEWAY AND SITE MASS GRADING WILL BE COMPLETED AS THE FIRST PHASE IN THE PROJECT. THE RESIDENCE ADDITION AND ASSOCIATED SITE FEATURES WILL BE CONSTRUCTED AS A SECOND PHASE, ONCE THE DRIVEWAY HAS BEEN CONSTRUCTED. THE PROJECT WILL HAVE A TOTAL DISTURBED AREA OF APPROXIMATELY 23.01 ACRES, WITHIN THE LIMITS OF THE DISTURBANCE, THE PRE -DEVELOPED CONDITION CONSISTS OF 20.23 ACRES OF MANAGED TURF AND 2.68 ACRES OF IMPERVIOUS AREA. THE PROPOSED POST -DEVELOPMENT CONDITION WILL CONSIST OF 20.42 ACRES OF MANAGED TURF AND 2.49 ACRES OF IMPERVIOUS AREA WITHIN THE LIMITS. 9.10 ACRES OF FORESTED/OPEN SPACE OUTSIDE OF THE LIMITS OF DISTURBANCE BUT WITHIN THE LIMITS OF THE SUBJECT PROPERTY WILL BE INCLUDED IN A PROPOSED CONSERVATION EASEMENT TO MEET WATER QUALITY REQUIREMENTS. THE PROJECT IS ANTICIPATED TO BEGIN IN AUGUST 2017 AND BE COMPLETED IN APPROXIMATELY 9 MONTHS. THE PROJECT WILL BE REQUIRED TO OPERATE UNDER A VIRGINIA STORMWATER MANAGEMENT PROGRAM CONSTRUCTION GENERAL PERMIT. B. EXISTING SITE CONDITIONS THE PROPERTY IS LOCATED NORTHEAST OF BARRACKS ROAD (SR -654), APPROXIMATELY 1.3 MILES FROM U.S. 250. A 156.8 ACRE PORTION OF THE INGLERIDGE FARM PROPERTY WAS PREVIOUSLY SUBDIVIDED FROM THE MAIN FARM HOUSE FOR FUTURE DEVELOPMENT. A GRAVEL ROAD AND STORMWATER MANAGEMENT FEATURES WERE INSTALLED APPROXIMATELY 10 YEARS AGO FOR A RESIDENTIAL SUBDIVISION. PROGRESS WAS HALTED ON THE SUBDIVISION AND THE 156.8 ACRES PROPERTY WAS RECENTLY PURCHASED FOR THE USE OF A RESIDENTIAL FARM. OVER THE PAST 10 YEARS, IT HAS BEEN VACANT BUT MAINTAINED AS A MIX OF PASTURES AND WOODS. RECENTLY, IT HAS BEEN FURTHER SUBDIVIDED INTO TWO PARCELS, BUT REMAINS UNDER THE SAME OWNERSHIP AND WILL BE DEVELOPED TOGETHER WITH THIS PROJECT. THE EXISTING GRAVEL ROAD( ALONG THE EASTERN EDGE OF THE PROPERTY IS PLANNED TO BE CONVERTED TO A DRIVEWAY BY REALIGNING AND NARROWING IT. THE OVERALL FARM HAS HILLS AND SLOPES DIRECTING RUNOFF IN ALL DIRECTIONS. THE PROPERTY GENERALLY HAS SLOPES OF 5-15% WITH STEEPER SLOPES UP TO 2:1 NEAR THE STREAMBEDS. RUNOFF FROM THE SITE FLOWS TOWARD STREAMS AND PONDS ON OR NEAR THE SITE. IVY CREEK RUNS ALONG THE WEST AND NORTH SIDES OF THE PROPERTY, A SMALL TRIBUTARY FLOWS FROM WEST TO EAST UNDER THE DRIVEWAY, APPROXIMATELY 500 -FEET FROM THE ENTRANCE OFF BARRACKS ROAD. THIS TRIBUTARY FLOWS TO A LARGER TRIBUTARY RUNNING FROM SOUTH TO NORTH ALONG THE EAST SIDE OF THE PROPERTY, AND EVENTUALLY COMBINES WITH IVY CREEK AT THE NORTH CORNER OF THE PROPERTY. A POND INSTALLED WITH THE SUBDIVISION WORK EXISTS NEAR THE CENTER OF THE SITE AND DISCHARGES INTO IVY CREEK. OVERALL, ALL RUNOFF ENDS UP IN IVY CREEK, FLOWING TO THE NORTH. THE PROPOSED DRIVEWAY WILL BE CONSTRUCTED FROM SOUTH TO NORTH ACROSS THE SUBJECT PROPERTY FOLLOWING EXISTING TOPOGRAPHY (WHEREVER POSSIBLE. C. ADJACENT PROPERTY THE INGLERIDGE FARM PROPERTY IS BORDERED BY AGRICULTURE LAND ON ALL SIDES. BARRACKS ROAD RUNS ALONG THE SOUTHWEST PROPERTY LINE, HOUSING SUBDIVISIONS ARE LOCATED TO THE SOUTHEAST AND SOUTH, AND OTHER FARM PROPERTIES SURROUND] THE REST OF THE PROPERTY. IVY CREEK AND ITS TRIBUTARIES FLOW AROUND THE NORTH, EAST AND WEST SIDES OF THE PROPERTY. D. PLANNED OFF SITE ACTIVITIES THIS PLAN AND PERMIT ONLY APPLIES TO ONSITE ACTIVITIES, SHOWN WITHIN THE LIMITS OF DISTURBANCE. ANY EXCESS OR UNSUITABLE MATERAL WILL BE TRANSPORTED TO AN OFF-SITE DISPOSAL AREA WITH AN APPROVED EROSION CONTROL PLAN BY THE AUTHORITY HAVING JURISDICTION. ALL OFF-SITE AREAS WHERE MATERIAL IS OBTAINED OR IS DISPOSED SHALL HAVE AN APPROVED EROSION CONTROL PLAN. THE NAMES OF ANY OFFSITE AREAS MUST BE PROVIDED TO ALBEMARLE COUNTY PRIOR TO BEING UTILIZED. E. SOILS A NATURAL RESOURCE CONSERVATION SERVICE (MRCS) CUSTOM SOIL RESOURCE REPORT FOR ALBEMARLE COUNTY, VIRGINIA DATED MARCH 29, 2017 SHOWS FOUR MAIN SOIL TYPES ON THE SITE; HAYESVILLE LOAM (49.60, HAYESVILLE CLAY LOAM (28.89), AiSHE LOAM (10.9%), AND TURBEVILLE LOAM (7.8%). NEARLY ALL SOILS ON SITE ARE CHARACTERIZED AS HYDROLOGIC SOIL GROUP B. FOR THE FULL REPORT, REFER TO APPENDIX A-1. F. CRITICAL EROSION AREAS THE SITE HAS SEVERAL CRITICAL EROSION AREAS THAT SHOULD BE MONITORED CLOSELY DURING CONSTRUCTION. ALL WORK NEAR AND WITHIN THE STREAM BUFFERS SHALL BE CHECKED FREQUENTLY TO ENSURE THE PROPOSED TRAPPING MEASURES ARE FUNCTIONING ADEQUATELY. ADJUSTMENTS AND REINFORCEMENTS SHOULD BE MADE WHERE NECESSARY TO MINIMIZE SEDIMENT LOSS INTO THE STREAM BUFFERS. ALSO, SEVERAL SLOPES BEING DISTURBED ARE CONSIDERED STEEP PER THE EROSIONS AND SEDIMENT CONTROL REGULATIONS. DURING EARTHWORK, ADDITIONAL SLOPES WITH NO VEGETATIVE COVER CAN BECOME CRITICAL IF PROPER MEASURES ARE NOT IMMEDIATELY TAKEN, INCLUDING SURFACE ROUGHENING AND STABILIZATION. REGULAR INSPECTIONS SHALL BE CONDUCTED ACROSS THE ENTIRE SITE TO ENSURE SLOPES 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. G. 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. UNLESS WAIVED OR APPROVED BY LOCAL ADMINISTRATOR, THE MINIMUM STANDARDS OF VESCR SHALL APPLY. H. STRUCTURAL PRACTICES 1.

PROVIDE REMEDIAL STABILIZATION AND SEEDING FOR A PERIOD OF ONE YEAR AFTER CONSTRUCTION. PART 2: STORMWATER MANAGEMENT REPORT A. STORMWATER MANAGEMENT OVERVIEW THE PROJECT WILL HAVE A TOTAL DISTURBED AREA OF APPROXIMATELY 23.01 ACRES. WITHIN THE LIMITS OF THE DISTURBANCE, THE PRE -DEVELOPED CONDITION CONSISTS OF 20.23 ACRES OF MANAGED TURF AND 2.68 ACRES OF IMPERVIOUS AREA. THE PROPOSED POST -DEVELOPMENT CONDITION WILL CONSIST OF 20.42 ACRES OF MANAGED TURF, 2.49 ACRES OF IMPERVIOUS AREA. THE RUNOFF FROM THE SITE IN BOTH THE PRE -DEVELOPED CONDITION FLOWS TO EXISTING STREAMS AND PONDS ON OR NEAR THE SITE. THE MAJORITY OF RUNOFF IN THE POST -DEVELOPED CONDITION WILL FLOW THROUGH ROADSIDE DITCHES BEFORE DISCHARGING INTO EXISTING STREAMS AND PONDS. ALL FLOWS IN THE POST -DEVELOPED CONDITION ARE CONSIDERED SHEET FLOW WHEN THEY LEAVE THE SITE. THE PROPOSED IMPROVEMENTS TO THE SITE TRIGGER THE REQUIREMENTS OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM (VSMP) REGULATIONS, SPECIFICALLY PART 11 B. TO HANDLE THE WATER QUALITY REQUIREMENTS, THE OWNER WILL DESIGNATE 9.1 ACRES ON THE PROPERTY AS CONSERVED OPEN SPACE. OVERALL STORMWATER CALCULATION INFORMATION DRAINAGE AREA FLOW RATE ANALYSIS WAS PERFORMED IN THE 'HYDRAFLOW HYDROGRAPHS' PROGRAM USING THE SCS METHOD. THE SOILS ONSITE WERE CLASSIFIED AS HYDROLOGIC GROUP B BASED ON THE NRCS SOIL REPORT. CURVE NUMBERS (CN) WERE BASED ON 98 FOR IMPERVIOUS AREAS AND 61 FOR GRASS AREAS IN B SOILS. REFER TO APPENDIX C FOR DRAINAGE AREA CALCULATIONS, TIME OF CONCENTRATIONS WERE DETERMINED BASED ON THE TR -55 METHOD. DRAINAGE AREAS WHERE THE SIZE AND SLOPES RESULTED IN A TIME OF CONCENTRATIONS BELOW FIVE MINUTES WERE DEFAULTED TO A MINIMUM VALUE OF FIVE MINUTES. TIME OF CONCENTRATION FLOW PATHS USE IMANNING'S N -VALUE OF 0.15 FOR GRASSED AREAS AND 0.030 FOR NATURAL CHANNELS. RAINFALL VALUES USED IN THE CALCULATIONS WERE BASED ON THE "NOAA ATLAS 14 POINT PRECIPITATION FREQUENCY ESTIMATES" FROM THE NOAH WEBSITE FOR ALBEMARLE COUNTY, VIRGINIA. REFER TO APPENDICES A-1. B. WATER QUALITY ANALYSIS THE STORMWATER REGULATIONS FOR LAND -DISTURBING ACTIVITIES DISTURBING MORE THAN ONE ACRE THAT RESULT IN NO NET INCREASE IN IMPERVIOUS COVER FROM THE PRE DEVELOPMENT CONDITION, (9VAC25-870-63 A.2.A) STATE THE TOTAL PHOSPHORUS LOAD SHALL BE REDUCED AT LEAST 20% BELOW THE PRE -DEVELOPMENT TOTAL PHOSPHORUS LOAD (AS CALCULATED PURSUANT TO 9VAC25-870-65). WATER QUALITY ANALYSIS WAS BASED ON THE VIRGINIA RUNOFF REDUCTION METHOD RE -DEVELOPMENT WORKSHEET - V3.0 (TO BE USED W/ DRAFT 2013 BMP STANDARDS AND SPECIFICATIONS). THE TOTAL DISTURBED AREA OF 23.01 ACRES IS USED AS THE SITE AREA. THIS AREA HAS A POST -DEVELOPED IMPERVIOUS AREA OF 2.49 ACRES (10.89), WHICH IS LESS THAN THE 2.68 ACRES IN THE PRE -DEVELOPED CONDITION. COMPLETING THE SPREADSHEETS RESULTS IN THE REQUIREMENT FOR 2.69 POUNDS OF PHOSPHORUS REMOVAL PER YEAR. TO SATISFY THE POLLUTANT REMOVAL REQUIREMENT, 9.1 ACRES WITHIN THE SUBJECT PROPERTY, OUTSIDE OF THE PROJECT LIMITS, HAS BEEN DESIGNATED AS CONSERVED OPEN SPACE. AS PER A CONVERSATION WITH MATT WENTLAND, ALBEMARLE COUNTY, THIS AREA MAY BE APPLIED AS MANAGED TURF IN THE PRE -DEVELOPED CONDITION AND CONVERTED TO OPEN SPACE IN THE POST -DEVELOPED CONDITION AS IT WILL NOW BE IN A PERMANENT EASEMENT. THIS ADDITIONAL CONSERVED OPEN SPACE REDUCES THE PHOSPHORUS LOAD BY 2.70 POUNDS PER YEAR, THEREFORE, THE WATER QUALITY REQUIREMENT IS SATISFIED. REFER TO APPENDIX C-1 FOR COMPLETED WATER QUALITY CALCULATIONS. THE OWNER'S LAWYERS WILL WORK WITH THE COUNTY TO DEVELOP THE PROPER DOCUMENTS SECURING CONSERVATION EASEMENTS FOR THE REQUIRED LAND PRIOR TO BEGINNING CONSTRUCTION. AN APPROXIMATE LOCATION OF THE EASEMENT IS SHOWN ON THE PLANS, HOWEVER, THE OWNER MAY CHOOSE A DIFFERENT LOCATION, AS LONG AS THE OVERALL AREA IS THE SAME. FINAL LOCATION WILL BE BASED ON PLATS RECORDED WITH THE COUNTY. C. CHANNEL PROTECTION ANALYSIS THE VIRGINIA STORMWATER MANAGEMENT PROGRAM (VSMP) REGULATIONS FOR CHANNEL PROTECTION (9VAC25-870-66 B) STATE, CONCENTRATED STORMWATER FLOW SHALL BE RELEASED INTO A STORMWATER CONVEYANCE SYSTEM AND SHALL MEET CERTAIN CRITERIA BASED ON THE TYPE OF SYSTEM (MANMADE, RESTORED OR NATURAL). ALL CONCENTRATED STORMWATER FLOWS FROM THE PROPOSED DRIVEWAY CHANNELS AND CULVERTS ARE CONVERTED TO SHEET FLOW PRIOR TO EXISTING THE SATE. FLOWS GREATER THAN 1 CFS FOR THE 2 -YEAR STORM ARE DIVERTED TO LEVEL SPREADERS AND DISCHARGES LESS THAN 1 CFS IN THE 2 -YEAR STORM HAVE BEEN DETERMINED TO BE NON-EROSIVE, AND THEREFORE NO ADDITIONAL MEASURES ARE REQUIRED. THEREFORE, THERE IS NO CONCENTRATED DISCHARGE ASSOCIATED WITH THIS DEVELOPMENT. D. FLOOD PROTECTION ANALYSIS THE VIRGINIA STORMWATER MANAGEMIENT PROGRAM (VSMP) REGULATIONS FOR FLOOD PROTECTION (9VAC25-870-66 C) STATE, CONCENTRATED STORMWATER FLOW SHALL BE RELEASED INTO A DOWNSTREAM CHANNEL WITH CAPACITY TO CONVEY THE POST -DEVELOPMENT PEAK FLOW FROM THE 10 -YEAR 24-HOUR STORM EVENT OR THE POST DEVELOPMENT PEAK FLOW RATE FOR THE 10 -YEAR 24-HOUR STORM EVENT MUST BE RELEASED AT A RATE LESS THAN THE PRE DEVELOPMENT PEAK FLOW RATE FROM THE 10 -YEAR 24-HOUR STORM EVENT. AS NOTED IN SECTION C, THERE IS NO CONCENTRATED DISCHARGE ASSOCIATED WITH THIS DEVELOPMENT. E. SHEET FLOW ANALYSIS THE VIRGINIA STORMWATER MANAGEMENT PROGRAM (VSMP) REGULATIONS FOR SHEET FLOW (9VAC25-870-66 D) STATES, INCREASED VOLUMES OF SHEET FLOW RESULTING FROM PERVIOUS OR DISCONNECTED IMPERVIOUS AREAS, OR FROM PHYSICAL SPREADING OF CONCENTRATED FLOW THROUGH LEVEL SPREADERS, MUST BE IDENTIFIED AND EVALUATED FOR POTENTIAL IMPACTS ON DOWN -GRADIENT PROPERTIES OR RESOURCES. THE MAJORITY OF THE DISTURBED AREAS NATURALLY SHEET FLOW OFF THE SITE AT NON-EROSIVE VELOCITIES. STORMWATER ACCUMULATED IN THE DRIVEWAY SWALES IS TEMPORARILY CHANNELIZED, BUT CONVERTED TO SHEET FLOW PRIOR TO LEAVING THE SITE. AS PER CONVERSATIONS WITH THE COUNTY, DISCHARGES LESS THAN 1 CFS IN THE 2 -YEAR STORM HAVE BEEN DETERMINED TO BE NON-EROSIVE, AND THEREFORE NO ADDITIONAL MEASURE BEYOND OUTLET PROTECTION IS REQUIRED TO MEET THE SHEET FLOW DEFINITION. IN TWO LOCATIONS, THE DISCHARGE FROM THE CONCENTRATED POINTS ARE GREATER THAN 1 CFS. THESE TWO LOCATIONS (SCC -4 & SCC -8) ARE DIRECTED TO LEVEL SPREADERS SIZED BASED ON THE VIRGINIA DEQ STORMWATER DESIGN SPECIFICATION NO. 2. PER SECTION 6.3 OF THIS SPECIFICATION, LEVEL SPREADERS SHALL BE 13 LINEAR FOOT PER CFS. THE 2 -YEAR FLOW FROM SCC -4 IS 1.26CFS AND SCC -8 IS 1.29CFS. THEREFORE, EACH OF THE LEVEL SPREADERS ARE SIZED AS 17 -FEET. OVERALL, THE IMPERVIOUS AREA IS REDUCED IN THE POST -DEVELOPED CONDITION. ALL RUNOFF FROM THE SITE IS CONVERTED TO SHEET FLOW, WHICH FLOWS TO NATURAL, UNDISBURSED LAND BEFORE ENTERING INTO THE SURROUNDING NETWORK OF STREAMS. THEREFORE, NO IMPACT TO DOWN -GRADIENT PROPERTIES ARE ANTICIPATED WITH THIS DEVELOPMENT. F. STORM SEWER SYSTEM ANALYSIS THE CULVERT AT THE ENTRANCE WAS ANALYZED IN THE 'HYDRAFLOW STORM SEWER" PROGRAM AND ALL SWALES WERE ANALYZED IN THE "HYDRAFLOW EXPRESS" PROGRAM. THE ONSITE CULVERTS ALL DEFAULTED TO A MINIMUM 15 -INCH DIAMETER. THE "WORST CASE" SCENARIO FOR THE CULVERTS WAS ANALYZED TO ENSURE 15 -INCH DIAMETER CULVERTS WILL CONVEY THE 10 -YEAR FLOW. ALL PIECES OF THE SYSTEM WERE ANALYZED TO CONVEY THE POST -DEVELOPED PEAK FLOW RATE FROM THE TWO-YEAR 24-HOUR STORM EVENT WITHOUT CAUSING EROSION OF THE SYSTEM AND TO CONFINE THE POST -DEVELOPED PEAK FLOW RATE FROM THE 10 -YEAR 24-HOUR STORM EVENT WITHIN THE SYSTEM, REFER TO APPENDIX D-1 FOR CALCULATIONS. G. MAINTENANCE THE CURRENT PROPERTY OWNER (MR. & MS. TIM DAVIS) WILL BE RESPONSIBLE FOR ENSURING PROPER MAINTENANCE OF THE STORM SEWER SYSTEM ON THE PROPERTY. A STORMWATER MANAGEMENT MAINTENANCE AGREEMENT WILL BE COMPLETED AND SUBMITTED PRIOR TO CONSTRUCTION. �A ,TH op - ,. ' C;.) E. AA BELL ON y Lie.
