88 - UDORTHENTS, LOAMY, 2-25 PERCENT SLOPES
HYDROLOGIC SOIL GROUP - D
SINKHOLES ARE NOT ANTICIPATED TO AFFECT THE SITE.
EROSION CONTROL PROGRAM
EROSION CONTROL SHALL BE MAXIMIZED THROUGH RAPID STABILIZATION OF THE DISTURBED AREAS AND BY INSTALLATION OF PERIMETER CONTROLS. NOT MORE THAN 7 CALENDAR
DAYS ARE TO ELAPSE WITH ANY DISTURBED AREA REMAINING DENUDED. TEMPORARY COVER, BY SEEDING AND/OR MULCHING, SHALL BE APPLIED TO AREAS THAT WILL BE EXPOSED FOR
A PERIOD OF GREATER THAN 7 DAYS, BEFORE PERMANENT STABILIZATION. PERMANENT COVER SHOULD BE PROVIDED OVER ALL DISTURBED AREAS AS SOON AS POSSIBLE UPON
ACHIEVING FINAL GRADE, BY MEANS OF SEEDING AND MULCHING, SODDING AND PEGGING, PAVING, OR AS OTHERWISE DIRECTED BY THE PLAN. LIKEWISE, ALL STOCKPILES SHALL BE
STABILIZED WITHIN 7 DAYS OF ACHIEVING FINAL GRADES. UTILITY TRENCHES SHALL BE SEEDED AND MULCHED WITHIN 7 DAYS AFTER BACKFILLING TO THE PROPOSED GRADE.
SEDIMENT CONTROL PROGRAM
SEDIMENT CONTROL SHALL BE ACCOMPLISHED THROUGH RAPID STABILIZATION AND BY THE INSTALLATION OF MECHANICAL DEVICES, AS SHOWN ON THE PHASE I PLAN:
STRUCTURAL PRACTICES
1. SAFETY FENCE - 3.01
TO BE PROVIDED TO PROHIBIT THE UNDESIRABLE USE OF AN EROSION CONTROL MEASURE BY THE PUBLIC.
2. CONSTRUCTION ENTRANCE - 3.02
TEMPORARY CONSTRUCTION ENTRANCES WITH WASH RACKS AND SETTLING AREAS ARE TO BE PROVIDED AT EACH POINT OF ACCESS TO THE SITE FOR THE DURATION OF
CONSTRUCTION. THE CONTRACTOR IS TO SUPPLY A WATER SOURCE BY PROVIDING A WATER TRUCKIWATER TANK ONSITE FOR WASHING CONSTRUCTION VEHICLES BEFORE
ENTERING THE PUBLIC ROAD.
3. SILT FENCE - 3.05
TO BE PROVIDED FOR INTERCEPTING AND DETAINING SEDIMENT FROM DISTURBED AREAS DURING CONSTRUCTION OPERATIONS TO PREVENT SEDIMENT FROM LEAVING THE SITE.
4. STORM DRAIN INLET PROTECTION - 3.07
A SEDIMENT FILTER OR AN EXCAVATED IMPOUNDING AREA AROUND A STORM DRAIN DROP INLET OR CURB INLET.
5. TEMPORARY SEEDING - 3.31
ESTABLISHMENT OF TEMPORARY VEGETATIVE COVER BY SEEDING WITH APPROPRIATE RAPIDLY GROWING PLANTS ON DISTURBED AREAS THAT WILL NOT BE BROUGHT TO FINAL
GRADE FOR A PERIOD OF MORE THAN 14 DAYS.
6. 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.
VEGETATIVE PRACTICES
1. SURFACE ROUGHENING - AREAS TO BE SEEDED SHALL BE LIGHTLY ROUGHENED AND LOOSE TO A DEPTH OF 2" TO 4" PRIOR TO SEEDING. AREAS WHICH HAVE BEEN GRADED AND
WILL NOT BE STABILIZED IMMEDIATELY MAY BE ROUGHENED TO REDUCE VELOCITY UNTIL SEEDING TAKES PLACE.
2. TOPSOILING (STOCKPILES) - TOPSOIL WILL BE STRIPPED FROM AREAS TO BE GRADED AND STOCKPILED FOR LATER USE. STOCKPILE ARE TO BE LOCATED ON -SITE IN OPEN SPACE
AREAS, AS DEPICTED ON THE PLAN, ARE TO BE STABILIZED WITH TEMPORARY VEGETATION, AND ARE TO BE SURROUNDED AT THE BASE BY SUPER SILT FENCE.
3. TEMPORARY SEEDING - ALL DENUDED AREAS THAT WILL BE LEFT DORMANT FOR EXTENDED PERIODS OF TIME SHALL BE SEEDED WITH FAST GERMINATING TEMPORARY VEGETATION
IMMEDIATELY FOLLOWING GRADING. SELECTION OF THE SEED MIXTURE WILL DEPEND ON THE TIME OF YEAR THAT IT IS APPLIED.
4. EROSION CONTROL BLANKETS OR MULCH - EROSION CONTROL BLANKETS WILL BE INSTALLED OVER FILL SLOPES WHICH HAVE BEEN BROUGHT TO FINAL GRADE AND SEEDED TO
PROTECT THE SLOPES FROM RILL AND GULLY EROSION AND ALLOW THE SEED TO GERMINATE PROPERLY. MULCH (STRAW OR FIBER) WILL BE USED ON RELATIVELY FLAT AREAS AND
WILL BE APPLIED AS A SECOND STEP IN THE SEEDING OPERATION.
ALL SILTATION CONTROL MEASURES ARE INTENDED TO PREVENT SEDIMENT FROM ENCROACHING INTO ENVIRONMENTALLY SENSITIVE AREAS OR ONTO ADJACENT PROPERTIES AND
ROADWAYS. THE FAUQUIER COUNTY INSPECTOR HAS THE AUTHORITY TO ADD OR DELETE EROSION AND SEDIMENT CONTROLS IN THE FIELD AS SITE CONDITIONS WARRANT. IN ADDITION,
NO SEDIMENT TRAPS OR SEDIMENT BASINS MAY BE REMOVED WITHOUT THE PRIOR APPROVAL OF THE COUNTY INSPECTOR.
UNLESS OTHERWISE NOTED, 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 (VESCH). THE MINIMUM STANDARDS OF VESCH SHALL BE ADHERED TO UNLESS
OTHERWISE WAIVED OR APPROVED BY A VARIANCE.

STORMWATER MANAGEMENT NARRATIVE
PROPOSED PERVIOUS AREA
13,756 SF - 0.32 AC
THE PROPOSED PROJECT IS FOR THE DEVELOPMENT OF A DISCOUNT TIRE STORE AND ASSOCIATED SITE IMPROVEMENTS. THE EXISTING PROPERTY IS CURRENTLY DEVELOPED AS A CLOSED FAST-FOOD RESTAURANT AND ADDITIONAL COMMERCIAL BUILDINGS IN THE REAR. THE TOTAL DISTURBED AREA IS 1.31
ACRES, WITHIN THIS AREA, THERE ARE 0.87 ACRES OF IMPERVIOUS AREA IN THE EXISTING CONDITION. THE POST DEVELOPMENT CONDITIONS WILL BE 78% (1.02 ACRES) IMPERVIOUS AND 22% (0.29 ACRES) PERVIOUS. THE SITE CONDITIONS WERE ANALYZED AT TWO POINTS OF INTEREST, POI 1 AND P012.
THE FIRST ANALYZED POINT OF INTEREST (POI 1) IS LOCATED TO THE NORTHWEST OF THE SITE THE SECOND ANALYZED POINT OF INTEREST (POI 2) IS LOCATED TO THE SOUTH OF THE SITE, ALONG SEMINOLE TRAIL, WHERE THE PROPOSED SITE RUNOFF CONVERGES AT THE SAME DOWNSTREAM POINT AND THE
REDUCTION OF RUNOFF WITHIN OUR DISTURBED AREA RESULTS IN AN IMPROVED DOWNSTREAM CONDITION.
WATER QUALITY REQUIREMENTS FOR THIS SITE WILL BE MET BY PURCHASING 0.66 LBS OF NUTRIENT OFFSET CREDITS.
WATER QUANTITY REQUIREMENTS WILL BE MET THROUGH THE USE OF A UNDERGROUND STORAGE CHAMBERS. THE CHAMBERS ARE AN ON -SITE DETENTION SYSTEM THAT UTILIZES A WEIR OUTFALL STRUCTURE. THIS MEASURE ATTENUATES THE POST DEVELOPMENT FLOWS TO MEET ENERGY BALANCE AND
FLOOD PROTECTION REQUIREMENTS.
THE PRE AND POST -DEVELOPMENT FLOW RATES FOR THE 1-YEAR, 2-YEAR AND 10-YEAR STORM EVENTS FOR THIS SITE WERE CALCULATED USING THE SCS METHOD IN THE PROGRAM AUTOCAD HYDRAFLOW HYDROGRAPHS.
TO CALCULATE THE RUNOFF REDUCTION REQUIRED TO MEET THE ENERGY BALANCE REQUIREMENTS, CURVE NUMBERS WERE CALCULATED USING VALUES FROM SCS TABLE 2.2A, RUNOFF CURVE NUMBERS FOR URBAN AREAS. RAINFALL DEPTHS USED TO CALCULATE FLOWS WERE TAKEN FROM NOAA ATLAS 14.
THE PRE -DEVELOPMENT FLOW RATES ARE SHOWN BELOW: THE POST -DEVELOPMENT FLOW RATES ARE SHOWN BELOW:
POI 1 POI 2 POI 1 POI 2
1-YEAR CFS: 0.284 1-YEAR CFS: 3.801 1-YEAR CFS: 0.041 1-YEAR CFS: 2.314
2-YEAR CFS: 0.390 2-YEAR CFS: 4.901 2-YEAR CFS: 0.058 2-YEAR CFS: 3.901
10-YEAR CFS: 0.724 10-YEAR CFS: 8.236 10-YEAR CFS: 0.112 10-YEAR CFS: 8.023
AS SHOWN IN THE POST DEVELOPED DRAINAGE PLAN ABOVE, THE RUNOFF FROM THE 1-YEAR, 2-YEAR AND 10-YEAR STORM EVENTS HAS BEEN REDUCED IN THE POST -DEVELOPMENT CONDITION TO LEVELS BELOW THE PRE -DEVELOPMENT CONDITION THEREFORE MEETING THE FLOOD PROTECTION
REQUIREMENT.
AS SHOWN ON THE ENERGY BALANCE CALCULATIONS ON THIS SHEET, THE REDUCTION IN THE POST DEVELOPMENT FLOWS ARE SUFFICIENT TO SATISFY THE ENERGY BALANCE EQUATION, THEREFORE MEETING THE CHANNEL PROTECTION REQUIREMENTS FOR THE SITE.
THE ALLOWABLE RELEASE RATE FOR ENERGY BALANCE WAS CALCULATED TO BE 3.14 CFS. THE COMBINED RELEASE RATE OF THE UNDERGROUND DETENTION SYSTEM WAS CALCULATED TO BE 3.13 CFS.
THEREFORE, BECAUSE BOTH FLOOD PROTECTION AND CHANNEL PROTECTION REQUIREMENTS HAVE BEEN MET FOR THE SITE, ALL STORMWATER QUANTITY REQUIREMENTS HAVE BEEN MET AND NO FURTHER CALCULATIONS ARE REQUIRED.
BEST MANAGEMENT PRACTICES NARRATIVE
SINCE THE SUBJECT SITE IS AN EXISTING DEVELOPED SITE, WATER QUALITY REQUIREMENTS FOR THE DEVELOPMENT OF THIS SITE WERE CALCULATED USING THE VIRGINIA RUNOFF REDUCTION METHOD (VRRM) REDEVELOPMENT SPREADSHEET. USING THIS SPREADSHEET IT WAS DETERMINED THAT THE
DEVELOPMENT OF THIS SITE WOULD REQUIRE THE TREATMENT OF AN ADDITIONAL 0.66 LB/YR OF PHOSPHOROUS REMOVAL.
TO MEET THIS REMOVAL REQUIREMENT, NUTRIENT OFFSET CREDITS WILL BE PURCHASED. SINCE THE PHOSPHOROUS REMOVAL ACHIEVED BY THESE CREDITS MEETS THE AMOUNT REQUIRED BY THE VRRM REDEVELOPMENT SPREADSHEET, ALL STORMWATER QUALITY REQUIREMENTS FOR THIS PROJECT HAVE
BEEN MET AND NO FURTHER ANALYSIS IS REQUIRED.
CONCLUSION
SINCE THE 1-YEAR, 2-YEAR, AND 10-YEAR FLOW RATES IN THE POST -DEVELOPED CONDITION MEET ENERGY BALANCE AND FLOOD PROTECTION, IN ADDITION TO THE PHOSPHOROUS REMOVAL RATE MEETING THE VRRM REDEVELOPMENT PHOSPHOROUS REMOVAL REQUIREMENT, IT IS THE OPINION OF THE
ENGINEER THAT THE STORMWATER QUANTITY AND QUALITY REQUIREMENTS ARE SATISFIED FOR THIS PROJECT.
ADEQUATE OUTFALL NARRATIVE
THE EXISTING SITE GENERALLY DRAINS TO THE SOUTH INTO EXISTING STORM INLETS ALONG THE EDGES OF THE SITE. THE RUNOFF IS THEN ROUTED EAST ALONG SEMINOLE TRAIL WHERE ALL OF THE SITE RUNOFF CONVERGES AT THE EXISTING STRUCTURE NOTED AS EX-1. THE PROPOSED DEVELOPMENT
CAPTURES AND DETAINS THE SITE RUNOFF BEFORE IT IS RELEASED AT POI-2 AT A RATE WHICH IS LESS THAN THE EXISTING CONDITION. SINCE THE OVERALL FLOWS TO POI-1 AND POI-2 AND ALL DOWNSTREAM STRUCTURES ARE REDUCED FOR THE 1-YEAR, 2-YEAR, AND 10-YEAR STORM EVENTS, THIS OUTFALL IS
CONSIDERED ADEQUATE. AS SUCH, IT IS THE OPINION OF THE ENGINEER THAT ADEQUATE OUTFALL REQUIREMENTS HAVE BEEN MET FOR THE SUBJECT SITE.

ENGINEERED SOLUTIONS STRONGLY SUGGESTS SCHEDULINGA
DETERMINE THE LIMITS OF EXCAVATION BEYOND THE SPRING LINE OF THE
MEASURES. THE PIPE CAN CARRY LIMITED FLUID PRESSURE WITHOUT
PRE -CONSTRUCTION MEETING WITH YOUR LOCAL SALES ENGINEER TO
