FOR THE ONE YEAR STORM EVENT, THE CURVE NUMBERS WERE DEVELOPED BY TAKING INTO ACCOUNT THE PARKING AREAS BEING TREATED WITH PERMEABLE PAVERS WHICH WILL FUNCTION IN A SIMILAR MANNER TO MANAGED TURF, WITH A PORTION OF THE RUNOFF BEING LOST TO INFILTRATION AND NOT ENTERING THE STORMWATER MANAGEMENT SYSTEM. FOR ALL REMAINING STORM EVENTS, 2, 10, AND 100 YEAR EVENTS, THE PARKING AREAS THAT ARE TREATED WITH PERMEABLE PAVERS WERE MODELED AS COMPLETELY IMPERVIOUS ASSUMING THAT THE RUNOFF WOULD ENTER THE STORMWATER SYSTEM AS IT NORMALLY WOULD FROM A PAVED AREA. BY MODELING THE AREA WITHIN POI - 11 IN THIS WAY IT PROVIDES THE MOST CONSERVATIVE, SAFEST AND MOST EFFICIENT SYSTEM POSSIBLE. CHANNEL PROTECTION THE CHANNEL PROTECTION REQUIREMENTS FOR POI-11 ARE BEING SATISFIED BY RELEASING THE POST DEVELOPED 1-YEAR STORMWATER RUNOFF AT A RATE LESS THAN THE ALLOWABLE RATE CALCULATED USING THE ENERGY BALANCE EQUATION PER SECTION 9VAC25-870-66 - B - 3a. OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM. THE DRAINAGE AREAS AND ASSOCIATED MAXIMUM ALLOWABLE FLOW RATES ARE SHOWN IN THE ENERGY BALANCE CALCULATION ON THIS SHEET AND THE STORMWATER OUTFALL TABLE ON THIS SHEET. IN ORDER TO RELEASE THE POST DEVELOPED 1-YEAR STORMWATER RUNOFF AT THE RATE SHOWN, A STORMWATER MANAGEMENT SYSTEM HAS BEEN DESIGNED THAT UTILIZES A SERIES OF BMPS, WHICH INCLUDES PERMEABLE PAVERS IN BLOCKS 4A AND THE TOWN CENTER COMMERCIAL AREA, UNDERGROUND DETENTION SYSTEMS IN BLOCKS 4A, 8A AND THE TOWN CENTER COMMERCIAL WHICH ARE ROUTED INTO A WET POND (POND 11) , AND ULTIMATELY RELEASED AS SHEET FLOW TO CONSERVED OPEN SPACE THROUGH A LEVEL SPREADER LOCATED AT THE OUTFALL FOR POI-11. THE CHANNEL PROTECTION REQUIREMENTS FOR POI-10 ARE ALSO BEING SATISFIED BY RELEASING THE POST DEVELOPED 1-YEAR STORMWATER RUNOFF AT A RATE LESS THAN THE ALLOWABLE RATE CALCULATED USING THE ENERGY BALANCE EQUATION PER SECTION 9VAC25-870-66 - B - 3a. OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM. THE DRAINAGE AREAS AND ASSOCIATED MAXIMUM ALLOWABLE FLOW RATES ARE SHOWN IN THE ENERGY BALANCE CALCULATION ON THIS SHEET AND THE STORMWATER OUTFALL TABLE ON THIS SHEET. IN ORDER TO RELEASE THE POST DEVELOPED 1-YEAR STORMWATER RUNOFF AT THE RATE SHOWN, A STORMWATER MANAGEMENT SYSTEM UTILIZES A SERIES OF BMPS WHICH INCLUDE A WET POND AND A LEVEL SPREADER THAT RELEASES THE RUNOFF AS SHEET FLOW TO CONSERVED OPEN SPACE. SINCE THE IMPROVEMENTS PROPOSED IN PHASE I OF THE ROAD IMPROVEMENT PLAN ARE CONTAINED WITHIN THE DRAINAGE AREAS CONTRIBUTING TO POI'S 10 AND 11, AND HAVE BEEN MODELED IN THE ABOVE MENTIONED CALCULATIONS, IT IS THE OPINION OF THE ENGINEER THAT CHANNEL PROTECTION REQUIREMENTS HAVE BEEN MET FOR POI'S 10 AND 11 AND THAT NO FURTHER ANALYSIS IS REQUIRED FOR THE PHASE 1 IMPROVEMENTS. FLOOD PROTECTION FLOOD PROTECTION REQUIREMENTS FOR POI-11 ARE BEING BY MET BY SATISFYING THE REQUIREMENTS SET IN SECTION 9VAC25-870-66 - C -1 AND 9VAC25-870-66 - C -3c. THE 10-YEAR 24 HOUR STORMWATER RUNOFF RELEASED FROM THE POND 11 IS CONVEYED IN A PROPOSED PIPE NETWORK WHICH HAS BEEN DESIGNED TO SAFELY CONVEY THE RUNOFF WITHIN THE SYSTEM AND IS DISCHARGED THROUGH OUTLET PROTECTION INTO AN EXISTING NATURAL CHANNEL ON SITE. CALCULATIONS FOR THE CAPACITY OF THE PROPOSED OUTFALL PIPE NETWORK CAN BE FOUND ON SHEET C-907. IN ADDITION THE EXISTING CHANNEL HAS BEEN ANALYZED AND FOUND TO ADEQUATELY CONTAIN THE 10-YEAR 24 HOUR RUNOFF TO THE POINT WHERE THE RUNOFF REACHES A MAPPED FLOODPLAIN. CALCULATIONS AND CHANNEL CROSS SECTIONS FOR THIS CHANNEL CAN BE FOUND ON SHEET C-907. SINCE BOTH THE PIPE AND EXISTING CHANNEL ARE SHOWN AS ADEQUATE, IT IS THE OPINION OF THE ENGINEER THAT FLOOD PROTECTION REQUIREMENTS HAVE BEEN MET FOR POI-11 AND NO FURTHER ANALYSIS IS REQUIRED. FLOOD PROTECTION REQUIREMENTS FOR POI-10 ARE BEING BY MET BY SATISFYING THE REQUIREMENTS SET IN SECTION 9VAC25-870-66 - C -1 AND 9VAC25-870-66 - C -3c. THE 10-YEAR 24 HOUR STORMWATER RUNOFF RELEASED FROM THE POND 10 IS CONVEYED IN A PROPOSED PIPE NETWORK WHICH HAS BEEN DESIGNED TO SAFELY CONVEY THE RUNOFF WITHIN THE SYSTEM AND IS DISCHARGED THROUGH OUTLET PROTECTION INTO AN EXISTING NATURAL CHANNEL ON SITE. THE EXISTING CHANNEL HAS BEEN ANALYZED AND FOUND TO ADEQUATELY CONTAIN THE 10-YEAR 24 HOUR RUNOFF TO THE POINT WHERE THE RUNOFF REACHES A MAPPED FLOODPLAIN. CALCULATIONS AND CHANNEL CROSS SECTIONS FOR THIS CHANNEL CAN BE FOUND ON SHEET C-906. SINCE THE EXISTING CHANNEL HAS BEEN FOUND TO BE ADEQUATE, IT IS THE OPINION OF THE ENGINEER THAT FLOOD PROTECTION REQUIREMENTS HAVE BEEN MET FOR POI-10 AND NO FURTHER ANALYSIS IS REQUIRED. ADEQUATE OUTFALL NARRATIVE AT THE POINT WHERE THE RUNOFF REACHES THE RIVER, THE CONTRIBUTING FLOW FROM THE SITE IS LESS THAN 1% OF THE TOTAL FLOW IN THE RIVER AND NO FURTHER ANALYSIS IS REQUIRED. ADDITIONALLY, AFTER BEING RELEASED AS SHEET FLOW THE RUNOFF FROM BOTH POI - 10 AND POI - 11 WILL EVENTUALLY REENTER EXISTING NATURAL CHANNELS THAT OUTFALL INTO THE RIVANNA RIVER. SINCE THE RELEASE FROM BOTH POI - 10 AND POI-11 IS LESS THAN WHAT IS ALLOWED BASED ON THE ENERGY BALANCE EQUATION (SEE ENERGY BALANCE CALCULATIONS ON THIS SHEET), AND THE POST DEVELOPED FLOW WILL BE ADEQUATELY CONVEYED INTO THE EXISTING CONVEYANCE CHANNELS THAT ARE IN A MAPPED FLOODPLAIN AND HAVE THE CAPACITY TO SAFELY CONVEY THE 10-YEAR RUNOFF TO THE RIVANNA RIVER, IT IS THE OPINION OF THE ENGINEER THAT THE ADEQUATE OUTFALL REQUIREMENT HAVE BEEN MET FOR BOTH POI - 10 AND POI - 11. WATER QUANTITY CONCLUSION IT IS THE OPINION OF THE ENGINEER THAT BECAUSE THE WATER QUALITY, CHANNEL PROTECTION, FLOOD PROTECTION, AND ADEQUATE OUTFALL REQUIREMENTS HAVE ALL BEEN SATISFIED, THE SITE IS IN COMPLIANCE AFTER THE PHASE I SECTION OF THE ROAD IMPROVEMENT PLANS HAVE BEEN COMPLETED AND NO FURTHER ANALYSIS OR CALCULATIONS ARE REQUIRED.

THE BMP MEASURES PROPOSED FOR POI-11 ARE DESIGNED TO BE A TREATMENT TRAIN IN ORDER TO ADEQUATELY REMOVE THE REQUIRED PHOSPHORUS. THIS SYSTEM STARTS WITH THREE (3) UNDERGROUND DETENTION SYSTEMS WITH ISOLATOR ROWS LOCATED IN BLOCKS 4A, 8A AND THE TOWN CENTER COMMERCIAL AREA. THE BUILDING ROOFTOPS IN THESE BLOCKS WILL BE TREATED BY ROUTING THE RUNOFF GENERATED FROM THE ROOF AREAS INTO THE UNDERGROUND DETENTION SYSTEMS VIA THE ISOLATOR ROWS. PERMEABLE PAVEMENT AND/OR PAVERS WILL BE USED TO TREAT THE THE PARKING AREAS IN BLOCKS 4A AND THE TOWN CENTER COMMERCIAL AREA, AND ANY RUNOFF NOT BEING INFILTRATED BY THE PERMEABLE PAVEMENT/PAVERS WILL ALSO BE ROUTED INTO THE UNDERGROUND DETENTION SYSTEMS IN THE RESPECTIVE BLOCKS. ALL RUNOFF RELEASED FROM THE UNDERGROUND DETENTION SYSTEMS IS THEN CONVEYED TO POND 11 THROUGH THE PROPOSED STORM SEWER SYSTEM. THE RUNOFF FROM THE PROPOSED ROAD AND THE MANAGED TURF/LANDSCAPED AREAS WITHIN THESE BLOCKS WILL ALSO BE CONVEYED TO POND 11 EITHER THROUGH THE PROPOSED STORM SEWER SYSTEM OR OVERLAND FLOW. THE STORMWATER RELEASED FROM POND 11 IS CONVEYED THROUGH THE OUTFALL PIPE NETWORK AND EXISTING NATURAL CHANNELS TO THE PROPOSED 48" CULVERT UNDER POLO GROUNDS ROAD. UPON REACHING THE CULVERT THE TREATED RUNOFF FROM POND 11 COMBINES WITH THE RUNOFF FROM THE UNTREATED AREAS, AND THE OFFSITE PORTION OF THE DRAINAGE AREA, AND FLOWS UNDER POLO GROUNDS ROAD WHERE IT IS RELEASED AS SHEET FLOW INTO CONSERVED OPEN SPACE BY A LEVEL SPREADER. IMPLEMENTING THE BMPS AS NOTED ABOVE PROVIDES A PHOSPHORUS REMOVAL RATE OF 37.99 LB/YR WHICH IS 9.84 LB/YR MORE THAN THE REQUIRED 28.17 LB/YR. FINAL DESIGN OF THE PERMEABLE PAVEMENT AND THE UNDERGROUND DETENTION SYSTEMS MENTIONED ABOVE WILL BE COMPLETED WITH THE FINAL WPO PLAN FOR EACH RESPECTIVE AREA. THE TREATMENT VALUES AND RELEASE RATES FOR THESE BMPs WILL MEET OR EXCEED THE VALUES SHOWN IN THE VRRM WORKSHEETS AND THE ASSOCIATED STORMWATER MANAGEMENT REPORT FOR THIS PLAN. FOR POI - 10 THERE ARE THREE (3) BMP MEASURES PROPOSED, IN A SIMILAR TREATMENT TRAIN AS POI - 11. THIS INCLUDES MANUFACTURED FILTERING DEVISES (FILTERRA'S), A WET POND (POND 10) AND A LEVEL SPREADER (LS-10) WHICH WILL RELEASE THE RUNOFF AS SHEET FLOW TO CONSERVED OPEN SPACE. THE COMBINATION OF THE THREE (3) BMPS PROVIDE A PHOSPHOROUS REMOVAL RATE OF 8.28 LB/YR WHICH IS 2.33 LB/YR MORE THAN THE REQUIRED 5.95 LB/YR. A SUMMARY OF THE PHOSPHORUS REMOVAL ACHIEVED OR PURCHASED CAN BE FOUND IN THE BROOKHILL STORMWATER QUALITY SUMMARY TABLE ON SHEET C-904. CONCLUSION IT IS THE OPINION OF THE ENGINEER THAT SINCE THE WATER QUALITY REQUIREMENTS HAVE BEEN SATISFIED FOR POI - 10 AND POI - 11 AS SHOWN ABOVE, AND ALL OF THE INFRASTRUCTURE ASSOCIATED WITH PHASE I OF THE ROAD IMPROVEMENT PLAN FALLS WITHIN THE DRAINAGE AREAS TO POI - 10 AND POI - 11, THAT THE PROPOSED ROAD PLAN IS IN COMPLIANCE AND NO FURTHER ANALYSIS OR CALCULATIONS ARE REQUIRED.
