CHANNEL PROTECTION THE CHANNEL PROTECTION REQUIREMENTS SET IN SECTION 9VAC25-870-66 OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM ARE BEING SATISFIED FOR POI'S 4.1 AND 4.2 BY ROUTING ALL CONCENTRATED FLOWS CREATED BY THE DEVELOPMENT THROUGH SEVERAL LEVEL SPREADERS THAT HAVE BEEN DESIGNED TO RELEASE THE TWO (2) YEAR FLOWS GENERATED FROM THE DEVELOPMENT AS SHEET FLOW TO CONSERVED OPEN SPACE. THIS IS ACCOMPLISHED FOR POI-4.1BY ROUTING THE POST DEVELOPED RUNOFF, FROM THE AREAS SHOWN ON THIS SHEET, TO POND 4 WHICH HAS BEEN DESIGNED TO RELEASE THE TWO YEAR STORM EVENT AT A PEAK FLOW RATE OF 3.80 CFS. THE DISCHARGE FROM POND 4 IS THEN ROUTED, THROUGH OUTLET PROTECTION, TO AN ENGINEERED LEVEL SPREADER WHICH RELEASES THE RUNOFF AS SHEET FLOW TO CONSERVED OPEN SPACE. THEREFORE, IT IS THE OPINION OF THE ENGINEER THAT BECAUSE THE TWO (2) YEAR RUNOFF GENERATED FROM THE PROPOSED ICE RINK, WILL BE ROUTED TO POND 4 AND ULTIMATELY RELEASED AS SHEET FLOW, THE CHANNEL PROTECTION REQUIREMENTS PER SECTION 9VAC25-870-66 OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM HAVE BEEN SATISFIED, AND NO FURTHER ANALYSIS IS REQUIRED FOR THE ICE RINK DEVELOPMENT AREA. THE POST DEVELOPED RUNOFF TO POI-4.2, GENERATED FROM THE ROAD AND TOWN HOME LOT AREAS SHOWN ON THIS SHEET, WILL BE ROUTED, THROUGH A COMBINATION OF STORM SEWER AND GRASS SWALES, TO ENGINEERED LEVEL SPREADERS AND RELEASED AS SHEET TO CONSERVED OPEN SPACE. THEREFORE, IT IS THE OPINION OF THE ENGINEER THAT BECAUSE THE RUNOFF GENERATED FROM THIS AREA WILL NOT BE RELEASED AS CONCENTRATED FLOW THE CHANNEL PROTECTION REQUIREMENTS PER SECTION 9VAC25-870-66 OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM HAVE BEEN SATISFIED FOR POI-4.2. A DETAILED DESIGN OF THE CONVEYANCE SYSTEM TO THE LEVEL SPREADERS, AND OF THE LEVEL SPREADERS THEMSELVES, WILL NEED TO BE PROVIDED AT THE TIME OF THE FINAL SITE PLAN FOR THIS AREA. IT IS THE OPINION OF THE ENGINEER THAT BECAUSE THE CHANNEL PROTECTION REQUIREMENTS SET IN SECTION 9VAC25-870-66 OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM HAVE BEEN MET, THE SITE IS IN COMPLIANCE AND NO FURTHER ANALYSIS IS REQUIRED WITH THIS PLAN. FLOOD PROTECTION FLOOD PROTECTION FOR POI-4.1 HAS BEEN SATISFIED BY CONVEYING THE TEN (10) YEAR PEAK FLOW THROUGH AN ADEQUATE CONVEYANCE SYSTEM TO A POINT WHERE IT IS RELEASED INTO A MAPPED FLOODPLAIN. IT IS THE OPINION OF THE ENGINEER THAT FLOOD PROTECTION REQUIREMENTS HAVE BEEN MET FOR POI-4.1 AND NO FURTHER ANALYSIS IS REQUIRED. ANALYZING THE RECEIVING CHANNEL TO A POINT WHERE THE CHANNEL ENTERS A MAPPED FLOODPLAIN. THE CHANNEL CROSS SECTIONS CAN BE FOUND ON SHEET C-904 OF THIS PLAN SET AND THE ANALYSIS SHOWS THAT THE 10-YEAR FLOWS FROM THE EXISTING UNDISTURBED DRAINAGE AREAS COMBINED WITH THE ONSITE POST DEVELOPED DRAINAGE AREAS ARE CONFINED WITHIN THE CHANNEL AND DO NOT CREATE ANY ADDITIONAL LOCALIZED FLOODING FLOOD PROTECTION REQUIREMENTS FOR POI-4.2 ARE BEING BY SATISFIED BY RELEASING THE POST DEVELOPED STORMWATER RUNOFF TO POI-4.2 AS SHEET FLOW, AND BY ANALYZING THE 10-YEAR POST DEVELOPED RUNOFF IN THE RECEIVING CHANNEL, TO THE POINT WHERE IT ENTERS A MAPPED FLOODPLAIN. BECAUSE THE EXISTING CHANNEL CAN ADEQUATELY CONVEY THE POST DEVELOPED FLOW AS SHOWN ON SHEET C-904, IT IS THE OPINION OF THE ENGINEER THAT FLOOD PROTECTION REQUIREMENTS HAVE BEEN MET FOR POI-4.2 AND NO FURTHER ANALYSIS IS REQUIRED. ADEQUATE OUTFALL NARRATIVE THE OUTFALLS FOR POI'S 4.1 AND 4.2 BOTH DRAIN TO EXISTING ON SITE STREAMS THAT CONVEYS THE RUNOFF TO A POINT WHERE THE CHANNEL CONVERGES WITH OTHER ONSITE STREAMS NEAR THE 100-YEAR MAPPED FLOODPLAIN. THE RUNOFF IS THEN CONVEYED THROUGH ANOTHER ONSITE CHANNEL TO A DUAL 5' X 5' BOX CULVERT UNDER POLO GROUNDS ROAD AND IS ULTIMATELY DISCHARGED INTO THE RIVANNA RIVER. SINCE THE 2-YEAR STORM RUNOFF IS RELEASED A SHEET FLOW FOR BOTH POI-4.1 AND POI-4.2, AND THE 10-YEAR RUNOFF FOR BOTH POI-4.1 AND POI-4.2 IS ADEQUATELY CONVEYED TO THE POINT WHERE IT REACHES A MAPPED FLOODPLAIN, IT IS THE PROFESSIONAL OPINION OF THE ENGINEER THAT THE ADEQUATE OUTFALL REQUIREMENTS FOR POIs 4.1 AND 4.2 HAVE BEEN MET. 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, THIS SITE IS IN COMPLIANCE WITH THE WATER QUANTITY SECTION 9VAC25-870-66 OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM AND NO FURTHER ANALYSIS OR CALCULATIONS ARE REQUIRED.
