R':;y'Ir I HL HRUHUSED PROJECT IS FOR THE DEVELOPMENT OF AN EXISTING PROPERTY TO CONSTRUCT A WAWA GAS FACILITY,AND CONVENIENCE STORE WITH ASSOCIATED SITE IMPROVEMENTS, THE EXISTING PROPERTY IS A DEVELOPED COMMERCIAL SITE FEATURING A BANK WITH ASSOCIATED PARKING INFRASTRUCTURE, WHICH WILL BE DEMOLISHED WITH THIS DEVELOPMEi�JT. WITHIN THE DISTURBED AREA, THERE ARE 0.67 ACRES OF IMPERVIOUS AREA IN THE EXISTING CONDITIONS. THE TOTAL DISTURBED AREA iS 1.95 ACRES. THE POST DEVELOPMENT CONDITIONS WILL BE 75% IMPERVIOUS (1.46 ACRES) AND 25% ,PERVIOUS (0.49 ACRES). THE PRE AND POST DEVELOPMENT CONDITIONS WERE BOTH ANALYZED AT 5 POINTS OF INTEREST (POI). THE ANALYZED POINTS OF INTEREST ARE LOCATED AT THE EDGES OF THE SITE IN THE NORTH, EAST, AND SOUTH CORNEIRS. AN EXISTING BIORETENTION FACILITY THAT SERVICES THE ADJACENT PROPERTY TO THE NORTH FOR WATER QUALITY WIILL BE REMOVED WITH THIS DEVELOPMENT. THE EXISTING BIORETENTION CURRENTLY PROVIDES 2.30 LBS OF PHOSPHOROUS REMOVAL. WATER QUALITY REQUIREMENTS FOR THIS SITE WILL BE MET BY PURCHASING 1.63 LBS OF NUTRIENT OFFSET (CREDITS FOR THE SITE TO BE DEVELOPED, AS WELL AS, 2.30 LBS OF ADDITIONAL NUTRIENT OFFSET CREDITS TO ACCOUNT FOR THE REMOVAL OF THE BIORETENTION FACILITY. WATER QUANTITY REQUIREMENTS WILL BE MET THROUGH THE USE OF AN UNDERGROUND STORMWATER DETENTION VAULT. THE VAULT 1S AN ON -SITE DETENTION SYSTEM THAT UTILIZES A WEIR PLATE OUTFALL STRUCTURE. THIS MEASURE ATTENUATES THE POST DEVELOPMENT FLOWS TO MEET ENERGY BALANCE AND FLOOD PROTECTION REQUIREMENTS. ADDITIONALLY, THIS VAULT HAS BEEN SIZED TO ACCOUNT FOR THE REMOVAL OF THE ADJACENT BIO-RETENTION FACILITY. THE PRE AND POST -DEVELOPMENT FLOW RATES FOR THE 1-YEAR, 2-YEAR AND 10-YEAR STORM EVENTS FOR THIS SITE WIERE CALCULATED USING THE SCS METHOD IN THE PROGRAM AUTOCAD HYDRAFLOW HYDROGRAPHS, AS SHOWN ON SHEETS #10 THROUGH #13. TO CALCULATE THE RUNOFF REDUCTION REQUIRED TO MEET THE ENERGY BALANCE REQUIREMENTS, CURVE NUMBERS V'VERE 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: POI 1 For 2 P01 3 P01 4 P01 5 1-YEAR CFS: 3,58 1-YEAR CES: 3.04 1-YEAR CFS: 1.06 1-YEAR CFS: 0.47 1-YEAR CFS: 0.11 2-YEAR CFS: 4.63 2-YEAR CFS: 3.81 2-YEAR CFS: 1.31 2-YEAR CFS: 0.61 2-YEAR CFS: 0.15 10-YEAR CFS: 7.73 10-YEAR CFS: 6.05 10-YEAR CFS: 2,04 10-YEAR CFS: 1.01 10-YEAR CFS: 0.28 THE POST -DEVELOPMENT FLOW RATES ARE SHOWN BELOW: POI I For 2 P01 3 POI 4 POI I 1-YEAR CFS: 2.52 1-YEAR CFS: 2.76 1-YEAR CFS: 1.06 1-YEAR CFS: 0.04 1-YEAR CFS: 0.04 2-YEAR CFS: 2.89 2-YEAR CFS: 3.39 2-YEAR CFS: L31 2-YEAR CFS: 0.05 2-YEAR CFS: 0,06 10-YEAR CFS: 7.42 10-YEAR CFS: 5.22 10-YEAR CFS: 2.04 10-YEAR CFS: 0.07 10-YEAR CFS: 0,11 1 I - TIIL r INLJ 71v)O I vCvcLl.Irr_U U"1114AUt FLAN, I HL RUNOFF FROM THE 1-YEAR, 2-YEAR AND 10-YEAR STORM EVENTS HAS BEEN REDUCED FOR ALL POI'S IN THE POST -DEVELOPMENT CONDITION TO LEVELS BELOW THE PRE -DEVELOPMENT CONDITION, THEREFORE MEETING THE FLOOD PROTECTION REQUIREMENT. POI 1 CURRENTLY RECEIVES THE EXISTING BANK SITE OF 1,32 ACRES WITH A CN OF 89. THE PROPOSED DRAINAGE TO POI 1 WILL BE INCREASED TO 1.67 ACRES WITH A CN OF 94 BY COLLECTING ADDITIONAL AREAS FROM POPS 2 4 RUNOFF GENERATED WILL BE REDUCED BELOW THE EXISTING RELEASE RATES FOR POI 1 WITH THE PROPOSED UNDERGRIOUND DETENTION FACILITY. ENERGY BALANCE COMPUTATIONS PROVIDED ON THE STORM COMPUTATIONS SHEET SHOW IT AT THE PROPOSED RELEASE RATES ARE LESS THAN THE ALLOWABLE RELEASE RATES. POI 2 CURRENTLY DRAINS TO AN EXISTING BIORETENTION FACILITY, WHICH WILL BE REMOVED WITH THIS DEVELOPMENT. THE POST DEVELOPMENT AREA TO THIS POI IS REDUCED FROM 0.89 ACRES WITH CN OF 93 TO 0,71 ACRES WITH A CN OF 96. THE OUTFALL POINT FOR POI 2 IS ALTERED WITH THE PROPOSED DEVELOPMENT BY REPLACING THE EXISTING MANHOLE TOP A,T STRUCTURE EX-A1 WITH A PROPOSED GRATE INLET TOP. THE PARKING LOT GRADES AROUND THE PROPOSED STRUCTUR BE REVISED TO ENSURE ADEQUATE DRAINAGE TO THE PROPOSED STRUCTURE. THE PROPOSED IMPROVEMENTS WITHIN THE EXISTING BIORETENTION AREA TO POI 2 DRAIN TO POI 1 UNDE E WILL R PROP OVERDETAINED WITHIN THE PROPOSED UNDERGROUND DETENTION FACILITY IN OSEM CONDITIONS. THE ADDITIONAL FLOWS ARE ORDER TO REDUCE THE POST DEVELOPED RELEASE RATES OF POl 2 TO LESS THAN THE EXISTING RELEASE RATES TO MEET ENERGY BALANCE PRESENTED ON THE STORM COMPUTATIONS SHEET. POI 3 CURRENTLY DRAINS TO EXISTING STORM STRUCTURE EX-A4. THE DRAINAGE AREA, POI LOCATION, AND IMPERVIOUS AREA WITHIN THE POI 3 DRAINAGE DIVIDE WILL REMAIN UNCHANGED WITH THE PROPOSED DEVELOPMENT AND WILL BYPASS THE UNDERG ROUND DETE NTION SYSTEM. NO CHANGES TO THE POI 3 RELEASE RATES ARE PROPOSED. POI 4 CURRENTLY RECEIVES THE SOUTHERN PORTION OF THE EAST BOUND LANE OF SEMINOLE TRAIL AND THE GREEN SPACE FRONTING THE SUBJECT SITE TOTALING 0.15 AC WiTH A CN OF 89. THE PROPOSED DEVELOPMENT WILL TURN LANE WITH THE PROPOSED RIGHT -IN RIGHT -OUT ENTRANCE ALONG SEMINOLE TRAIL. THE PROPOSED TURN LANE A CREATE A RIGHT ND GREEN SPACE FRONTING THE PROPOSED WAWA FACILITY AND CONVENIENCE STORE WILL DRAIN TO THE UNDERGROUND DETENTION FACILITY, THE POST DEVELOPED DRAINAGE AREA TO POI 4 IS REDUCED TO 0.01 AC WITH CN OF 98, RESULTING IN THE POST DEVELOPED RELEASE RATES BEING REDUCED BELOW THE PRE DEVELOPED RELEASE RATES. POI 5 CURRENTLY RECEIVES GREEN SPACE FRONTING THE SUBJECT SITE AND ADJACENT HOSPITAL PROPERTY WITH AN AREA OF 0.05 AC WITH A CN OF 80. THE PROPOSED DEVELOPMENT WILL INSTALL A PORTION OF THE RIGHT -IN RIGHT -OUT ENTRANCE WITHIN THIS GREEN SPACE AND ROUTE THE IMPROVED AREA TO THE UNDERGROUND DETENTION FACILITY. THE REMAINING DRAINAGE IN THE POST DEVELOPED CONDITION IS REDUCED TO 0.02 AC WITH A CN OF 80, RESULTING IN THE POST DEVELOPED RELEASE RATES BEING REDUCED BELOW THE PRE DEVELOPED RELEASE RATES. AS SHOWN ON THE ENERGY BALANCE CALCULATIONS ON THE STORM COMPUTATIONS SHEET, THE REDUCTION IN THE POST DEVELOPMENT FLOWS ARE SUFFICIENT TO SAT, F PROTECTION REQUIREMENTS. S Y THE ENERGY BALANCE EQUATION. THEREFORE, MEETING THE CHANNEL SINCE BOTH FLOOD PROTECTION AND CHANNEL PROTECTION REQUIREMENTS HAVE BEEN SATISFIED, ALL STORMWATER QUANTITY REQUIREMENTS HAVE BEEN MET AND NO FURTHER ANALYSIS OR CALCULATIONS ARE REQUIRED, BEST MANAGEMENT PRACTICES NARRATIVE SINCE THE SUBJECT SITE IS AN EXISTING COMMERCIAL SITE, WATER QUALITY REQUIREMENTS FOR THE DEVEL OPMENT OF lfHi5 SITE WERE CALCULATED USING THE VIRGWIA RUNOFF REDUCTION METHOD (VRRM) RE -DEVELOPMENT COMPLIANCE SPREADSHEET. USING THIS SPREADSHEET IT WAS DETERMINED THAT THE DEVELOPMENT OF THIS SITE WOULD REQUIRE TIHE TREATMENT OF AN ADDITIONAL 1.63 LB/YR OF PHOSPHOROUS REMOVAL. TO MEET THIS REMOVAL REQUIREMENT, NUTRIENT OFFSET CREDITS WILL BE PURCHASED. SINCE THE PHOSPHOROUS REMOVAL ACHIEVED BY T HESE CREDITS MEETS THE AMOUNT REQUIRED BY THE VRRM NEW DEVELOPMENT COMPLIANCE SPREADSHEET, ALL STORMWATER QUALITY REQUIREMENTS FOR THIS PROJECT HAVE BEEN MET AND NO FURTHER ANALYSIIS IS REQUIRED. CONCLUSION SINCE THE 1-YEAR, 2-YEAR, AND 10-YEAR FLOW RATES IN THE POST -DEVELOPED CONDITION MEET ENERGY BALANCE AND TIHE PHOSPHOROUS REMOVAL RATE MEETS THE VRRM NEW DEVELOPMENT 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 PROPOSED DEVELOPMENT BYPASSES 0.28 ACRES OF DISTURBED WATER WITH A CN OF 98, AND DETAINS THE REMAINING IMPROVEMENT AREA OF 1.67 ACRES WITH A CN OF 94. SINCE THE OVERALL FLOWS TO POI 1 FOR THE 1-YEAR, 2-YEAR AND 10-YEAR STORM EVENTS ARE REDUCED WITH THE DEVELOPMENT OF THIS SITE, AND THE DETENTION SYSTEM OVERDETAINS THE 1-YEAR TO MEET ENERGY BALANCE THIS OUTFALL POINT IS CONSIDERED ADEQUATE. AS SUCH, IT IS THE OPINION OF THE ENGINEER THAT ADEQUATE OUTFALL REQUIREMENTS HAVE BEEN MET FOR THE SUBJECT SITE, HA161V762083\DRAWINGS\PLAN SETSIVSMP PLAN\V162083SD1.DWG PRINTED BY.

THE ALLOWABLE RELEASE RATE FOR THE 1 YEAR FOR THE REMAINING DISTURBED AREA IS 0.82 CFS. NO DETENTION MEASURES ARE APPLIED TO THIS DRAINAGE RESULTING IN A RELEASE RATE OF 0.84. POI 1 AND THE REMAINING UNDETAINED DISTURBED AREA REACH THE SAME ULTIMATE POI IN THE DOWNSTREAM DRAINAGE SYSTEM. THEREFORE THE OVERDETENTION OF POI I OF 2.52 CFS WITH AN ALLOWABLE RELEASE RATE OF 2.80 CFS IS IN EXCESS OF THE ALLOWABLE RELEASE RATE. THE COMBINED ALLOWABLE RELEASE RATES FOR POI AND THE UNDETAINED DISTURBED AREA IS 2.80 +0.82 = 3.62 CFS. THE PROPOSED RELEASE RATE FOR POI 1 AND THE UNDETAINED DISTURBED AREA IS 2.52 + 0.84 = 3.36 CFS. THEREFORE, THE SITE IS COMPLIANT FOR ENERGY BALANCE AND MEETS CHANNEL PROTECTION REQUIREMENTS.
