CHANNEL Area, CN & FLOOD PROTECTION COMPLIANCE ARE MET IN ACCORDANCE WITH MINIMUM 9 VAC 25-870-66 ac. REQUIREMENTS. PLEASE SEE THE ATTACHED STORMWATER MANAGEMENT CALCULATIONS PACKET FOR ADDITIONAL DETAILS PERTAINING TO THIS PLAN's STORMWATER QUANTITY COMPLIANCE. DA B (Post-Dev.) 73 7.97 WATER QUANTITY SUMMARY THE VAST MAJORITY OF THIS PLAN's PROPOSED DEVELOPMENT IS CAPTURED VIA STORMWATER CONVEYANCE WATERSHED SUMMARY FOR SUBAREA C SYSTEMS. THE PROPOSED STORM SEWER SYSTEMS DISCHARGE INTO THREE PROPOSED STORMWATER MANAGEMENT FACILITIES, EACH OF WHICH HAS A CONCENTRATED OUTFALL. SWM FACILITY 'B' F1ATTENUATES CN Area, RUNOFF FROM SUBAREA 'B', SWM FACILITY 'C' ATTENUATES RUNOFF FROM SUBAREA 'C' AND SWM FACILITY ac. n D' ATTENUATES RUNOFF FROM SUBAREA'D'. CHANNEL AND FLOOD PROTECTION ANALYSES WERE PERFORMED AT ALL THREE OF THESE FACILITIES' CONCENTRATED OUTFALLS. DA C (Post-DeV.) 75 9.01 FROM A CHANNEL PROTECTION STANDPOINT, ALL THREE STORMWATER MANAGEMENT FACILITIES ARE NS, DIAMETERS, SLOPES, etc.) OF YARD COMPLIANT WITH 9 VAC 25-870-66 SUBSECTION B.3.a (ENERGY BALANCE) AND THE LIMITS OF ANALYSES WATERSHED SUMMARY FOR SUBAREA D DRAINS WILL BE PROVIDED WITH THE FINAL SITE PLAN. _ STOP AT THE SWM FACILITIES SINCE SUBSECTION B.3.a IS MET. FROM A FLOOD PROTECTION STANDPOINT, 2. ALL ROOF DRAINAGE SCHEMATICALLY SHOWN WITHIN ALL THREE SUBAREAS ARE COMPLIANT WITH 9 VAC 25-870-66 SUBSECTION C.2.a (CONFINES THE 10-yr CN Area, POST -DEVELOPMENT SUBAREAS B, C & D DRAINING TO SWM FACILITIES POST-DEV. STORM EVENT WITHIN the SWM FACILITIES AND THEIR OUTFALL PIPES). THE FLOOD PROTECTION — ac SHALL BE PIPED DIRECTLY TO YARD DRAINS, OR SHEET FLOW TO LIMITS OF ANALYSES FOR THE THREE SWM FACILITIES IS SET BY SUBSECTION C.3.c (THE SWM FACILITIES INLETS, AND SHALL BE DETAINED VIA THE PROPOSED SWM FACILITIES.
