STORM WATER RUNOFF CONSIDERATIONS. EROSION AND SEDIMENT CONTROL NARRATIVE I. PROJECT DESCRIPTION: THE SUBJECT SITE IS LOCATED WITHIN THE BROOKHILL DEVELOPMENT ALONG US ROUTE 29 SEMINOLE TRAIL ROAD. THE SITE IS LOCATED ADJACENT TO STELLA LANE BETWEEN THE INTERSECTIONS WITH SALAMANDER STREET AND POLO GROUNDS ROAD. THE TOTAL DISTURBED AREA FOR THIS PLAN IS 5.07 ACRES. THE PURPOSE OF THIS PROJECT IS TO DEVELOP BLOCK BA BY CONSTRUCTING A SENK)R LIVING FACILITY. TO SERVICE THE PROPOSED DEVELOPMENT THIS PLAN WILL ALSO INCLUDE THE INSTALLATION OF SANITARY SEWER, WATER LINES, AND STORM INFRASTRUCTURE THAT WILL SERVE THE PROPOSED SENIOR LIVING FACILITY. RUNOFF FROM THE SITE WILL BE CONVEYED TO POND-11 BEFORE OUTFALLING AT THE LEVEL SPREADER AT POI-11, THE TOTAL PROJECT IS ANTICIPATED TO TAKE NINE (9) TO TWELVE (12) MONTHS TO COMPLETE. 11, EXISTING SITE CONDITIONS: THE SUBJECT SITE IS CURRENTLY UNDEVELOPED AND HAS BEEN PREVIOUSLY ROUGH GRADED TO ALLOW FOR THE INSTALLATION AND GRADING TIE OUT OF THE ROADS MENTIONED ABOVE. THE REMAINING UNDISTURBED PORTIONS OF THE SITE ARE PRIMARILY ROLLING TERRAIN WITH SLOPES THAT RANGE FROM APPROXIMATELY 1% TO 50%. NO PART OF THE SUBJECT SITE CONTAINS AREA IN THE 100-YEAR FLOODPLAIN, AND NO WETLANDS OR STREAM CORRIDORS ARE IDENTIFIED. Ill. ADJACENT PROPERTY: THE SITE IS BORDERED TO THE NORTH BY THE BLOCK 4A APARTMENTS, TO THE EAST BY SEMINOLE TRAIL (RTE. 29), TO THE SOUTH BY POND-11 AND OPEN SPACE, AND TO THE WEST BY STELLA LANE. IV. OFFSITE AREAS: THE PROPOSED PROJECT HAS BEEN DESIGNED TO MINIMIZE THE IMPORT AND/OR EXPORT OF DIRT FOR THE SITE. HOWEVER, IT IS ANTICIPATED THAT THERE WILL BE EXCESS CUT GENERATED DURING CONSTRUCTION THAT WILL NEED TO BE TRANSPORTED TO AREAS WITHIN THE PROPOSED DEVELOPMENT THAT WERE INCLUDED IN THE PREVIOUSLY APPROVED WPO PLAN NWP020170DO37. THE CONTRACTOR IS RESPONSIBLE FOR COORDINATING ANY DISTURBANCE OFFSITE AND FOR ANY REQUIRED PLANS AND PERMITS THAT MAY BE REQUIRED. V. SOILS: A O E TECHNICAL STUDY HAS NOT BEEN PERFORMED AT THIS TIME. A STUDY WILL BE PREPARED AT A FUTURE DATE. PER G THE USGS WEB SOIL SURVEY, THE SOILS OF BLOCK eA ARE ENTIRELY HSG B. THE ONLY OTHER SOILS RELEVANT TO THIS PLAN ARE HSG D SOILS, LOCATED ADJACENT TO AND SOUTH OF POLO GROUNDS ROAD, AT POI 11, AS SHOWN IN THE STORMWATER COMPLIANCE CALCULATIONS. W. CRITICAL AREAS: CRITICAL AREAS ARE KNOWN TO CURRENTLY EXIST ON SITE ALONG THE 2:1 SLOPES AROUND THE PERIMETER OF THE SITE WHERE THE BLOCK 4A APARTMENTS AND POND-11 GRADES TIE INTO EXISTING GRADES.

OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM. THE CONTRIBUTING DRAINAGE AREAS AND ASSOCIATED MAXIMUM ALLOWABLE FLOW RATES ARE SHOWN IN THE ENERGY BALANCE CALCULATION AND THE STORMWATER OUTFALL TABLE ON THIS SHEET. IN ORDER TO RELEASE THE POST DEVELOPED 1-YEAR STORMWATER RUNOFF AT THE RATE SHOWN, THE VIRGINIA RUNOFF REDUCTION METHOD WORKSHEET WAS USED TO DETERMINE AN ADJUSTED CURVE NUMBER (SEE SHEET C-902) FOR THE BLIP DEVICES ONSME. AS THE POST DEVELOPED RUNOFF TO POW i IS ABLE TO BE CONTROLLED AND RELEASED AT A RATE LESS THAN THAT REQUIRED RATE PER THE ENERGY BALANCE EQUATION, NO FURTHER ANALYSIS IS REQUIRED FOR POW 1. IT IS THE OPINION OF THE ENGINEER THAT BECAUSE THE CHANNEL PROTECTION REQUIREMENTS SET IN SECTION 9VAC25A70-66 OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM HAVE BEEN MET, THE SITE IS IN COMPLIANCE AND NO FURTHER ANALYSIS IS REQUIRED. FLOOD PROTECTION FLOOD PROTECTION ANALYSIS FOR POI-11 WAS CONDUCTED AS PART THE WPO PLAN TITLED "VIRGINIA STORMWATER MANAGEMENT PLAN WPO201800013 FOR ROAD IMPROVEMENT PLAN PHASE I' AND FOUND TO BE ADEQUATE DURING THIS ANALYSIS. THE 10-YEAR PEAK FLOWS ASSOCIATED WITH THE PROPOSED IMPROVEMENTS MADE IN BLOCK BA ARE ADEQUATELY CONVEYED THROUGH THE EXISTING AND PROPOSED STORM NETWORKS TO POND -11, WHERE IT IS DETAINED AND RELEASED FROM THE POND INTO CHANNEL C-6, WHICH 15 ADEQUATELY SIZED TO CONVEY THE 10 YEAR FLOW WITH NO FLOODING, AS SHOWN ON "CHANNEL REPORT- C610 YEAR" ON THE FOLLOWING SHEET. THEREFORE, IT IS THE OPINION OF THE ENGINEER THAT BLOCK SA IS IN COMPLIANCE WITH SECTION 9VAC2567068 - C -1 AND 9VAC2567066 - C -3C OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM, AND NO FURTHER ANALYSIS IS REQUIRED. ADEQUATE OUTFALL NARRATIVE IN ORDER FOR THE RUNOFF TO CONVEY TO THE LIMIT OF ANALYSIS, IT MUST TRAVEL THROUGH A SERIES OF MANMADE PIPES AND SWALES TO POND 11 TO ULTIMATELY OUTFALL AT POI-11. ADEQUACY OF THE STORMWATER SYSTEM FROM BLOCK SA TO POND 11 IS SHOWN ON THIS SHEET. FROM POND 11, RUNOFF WILL OUTFALL INTO THE EXISTING NATURAL STREAM, THE STREAM INTERSECTS POLO GROUNDS ROAD AT CULVERT A01 TO A40, WHICH OUTFALLS TO THE LEVEL SPREADER AT POI-11. CHANNEL AND CULVERT COMPUTATIONS CAN BE FOUND ON SHEET C-902. SINCE BLOCK SA HAS BEEN FOUND TO BE ADEQUATE WITH THE EXISTING STORM NETWORK AND THE 10-YEAR STORM RUNOFF IS CONTROLLED AND CONTAINED IN THE MANMADE AND NATURAL SYSTEMS DOWNSTREAM OF BLOCK SA, IT IS THE PROFESSIONAL OPINION OF THE ENGINEER THAT THE ADEQUATE OUTFALL REQUIREMENTS FOR POIA 1 HAVE BEEN MET.

FOR BLOCK BA, RUNOFF FROM THE SITE WILL BE CONVEYED INTO THE PROPOSED STORM NETWORK AND ROUTED TO POND 11 WITH A SMALL PORTION BYPASSING THE STORM NETWORK AND BEING CHANNELED DIRECTLY TO POND 11. ADDITIONALLY, 0.65 ACRES OF PERVIOUS LAND COVER WILL BYPASS THE EXISTING AND PROPOSED STORM NETWORKS AND BE CHANNELED TO THE LEVEL SPREADER AT POI-11. BY IMPLEMENTING THE BMPB AS NOTED ABOVE, THE STORMWATER MANAGEMENT DESIGN IS ABLE TO ACHIEVE A PHOSPHORUS REMOVAL RATE OF 5.71 LB/YR. THIS DESIGN REMOVES THE TOTAL AMOUNT REQUIRED AND NO FURTHER ACTION FOR STORMWATER QUALITY COMPLIANCE IS WARRANTED. CONCLUSION WITH THE AREAS AND LAND COVERS NOTED ABOVE THE TOTAL PHOSPHORUS LOAD REDUCTION REQUIRED FOR THIS LAND DISTURBING ACTIVITY IS 5.68 URNEAR. THE Bill MEASURES NOTED ABOVE ARE ABLE TO ACHIEVE A PHOSPHORUS LOAD REDUCTION OF 5.69 US/YEAR, WHICHS GREATER THAN THE REQUIRED AMOUNT, AND THEREFORE ACCEPTABLE FOR THE VIRGINIA RUNOFF REDUCTION METHOD, IT IS THE OPINION OF THE ENGINEER THAT ALL WATER QUALITY REQUIREMENTS HAVE BEEN SATISFIED FOR THIS LAND DISTURBING ACTIVITY AND NO FURTHER ANALYSIS IS REQUIRED.
