ACTION: SEE EROSION AND SEDIMENT CONTROL NARRATIVE, SECTION XI. 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 5.17 ACRES. THE PURPOSE OF THIS PROJECT IS TO DEVELOP BLOCK 8A BY CONSTRUCTING A SENIOR 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-1 1. THE TOTAL PROJECT IS ANTICIPATED TO TAKE NINE (9) TO TWELVE (12) MONTHS TO COMPLETE. II. 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. III. 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 #WP0201700037. THE CONTRACTOR IS RESPONSIBLE FOR COORDINATING ANY DISTURBANCE OFFSITE AND FOR ANY REQUIRED PLANS AND PERMITS THAT MAY BE REQUIRED. V. SOILS: A GEOTECHNICAL STUDY HAS NOT BEEN PERFORMED AT THIS TIME. A STUDY WILL BE PREPARED AT A FUTURE DATE. PER THE USGS WEB SOIL SURVEY, THE SOILS OF BLOCK 8A 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. VI. 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. VII. EROSION AND SEDIMENT CONTROL MEASURES: UNLESS OTHERWISE NOTED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL PRACTICES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO MINIMUM STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK (VESCH). THE MINIMUM STANDARDS OF VESCH SHALL BE ADHERED TO UNLESS OTHERWISE WAIVED OR APPROVED BY A VARIANCE. SPECIFIC EROSION AND SEDIMENT CONTROL MEASURES UTILIZED IN THIS PROJECT INCLUDE THE FOLLOWING: 1. CONSTRUCTION ENTRANCE - 3.02 A PAVED PAD LOCATED AT POINTS OF VEHICULAR INGRESS AND EGRESS ON A CONSTRUCTION SITE. 2. SILT FENCE - 3.05 A PROTECTIVE BARRIER TO INTERCEPT AND DETAIN SMALL AMOUNTS OF SEDIMENT FROM DISTURBED AREAS DURING CONSTRUCTION OPERATIONS IN ORDER TO PREVENT SEDIMENT FROM LEAVING THE SITE. 3. SUPER SILT FENCE - N/A REINFORCED SILT FENCE TO INTERCEPT AND DETAIN SMALL AMOUNTS OF SEDIMENT FROM DISTURBED AREAS DURING CONSTRUCTION OPERATIONS IN ORDER TO PRESENT SEDIMENT FROM LEAVING THE SITE. 4. STORM DRAIN INLET PROTECTION - 3.07 A SEDIMENT FILTER OR AN EXCAVATED IMPOUNDING AREA AROUND A STORM DRAIN DROP INLET OR CURB INLET. 5.

WHILE THESE CONDITIONS ARE SHOWN RELATE TO THE APARTMENTS AND ROAD IMPROVEMENT PORTIONS OF THE PROJECT, PRE -DEVELOPED CURVE NUMBERS (FOREST AND MEADOW) ARE USED FOR THE STORMWATER MANAGEMENT CALCULATIONS IN ORDER TO ENSURE AN ACCURATE DEPICTION OF PRE VS. POST DEVELOPED CONDITIONS. THE SUBJECT SITE HAS ONE (1) POI, POI-11. THE EXISTING CONDITIONS OF THE SUBJECT AREA ARE MOSTLY FOREST AND MEADOW AREAS. THERE ARE NO KNOWN EXISTING STRUCTURES LOCATED WITHIN THE SUBJECT AREA. THE EXISTING TOPOGRAPHY IN THE SUBJECT AREA HAS SLOPES RANGING FROM APPROXIMATELY 5% UP TO 40% WITH AREAS OF PRESERVED AND MANAGED SLOPES AS SHOWN ON THIS SHEET. DRAINAGE AREA 11 HAS A PRE DEVELOPED AREA OF 42.34 AC. AND A CURVE NUMBER OF 61. THE PRE DEVELOPED FLOWS FOR THE 1-YEAR, 2-YEAR, AND 10-YEAR STORM EVENTS FROM DRAINAGE AREA 11 ARE 10.76 CFS, 23.44 CFS, AND 76.55 CFS, RESPECTIVELY. ALL OF THE RUNOFF FROM DRAINAGE AREA 11 IS CALCULATED TO FLOW DIRECTLY TO POI 11, WITHOUT BEING ROUTED THROUGH POND 11 TO PRESENT THE CONDITIONS BEFORE THE PROJECT COMMENCES.

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 BMP DEVICES ONSITE. AS THE POST DEVELOPED RUNOFF TO POI 11 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 POI-11. 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. FLOOD PROTECTION FLOOD PROTECTION ANALYSIS FOR POI-11 WAS CONDUCTED AS PART THE WPO PLAN TITLED "VIRGINIA STORMWATER MANAGEMENT PLAN WP0201800013 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 8A 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 IS ADEQUATELY SIZED TO CONVEY THE 10 YEAR FLOW WITH NO FLOODING, AS SHOWN ON "CHANNEL REPORT - C-6 10 YEAR" ON THE FOLLOWING SHEET. THEREFORE, IT IS THE OPINION OF THE ENGINEER THAT BLOCK 8A IS IN COMPLIANCE WITH SECTION 9VAC25-870-66 - C -1 AND 9VAC25-870-66 - 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 8A TO POND 11 SHALL BE SHOWN IN THE BLOCK 8A FINAL SITE PLAN WITH THE DETAILED 1STORMWATER COMPUTATIONS AND ANALYSIS. FROM POND 11 RUNOFF WILL OUTFALL INTO THE EXISTING NATURAL STREAM. THE STREAM INTERSECTS POLO GROUNDS fYOAD 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 8A 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 8A, IT IS THE PROFESSIONAL OPINION OF THE ENGINEER THAT THE ADEQUATE OUTFALL REQUIREMENTS FOR POI-11 HAVE BEEN MET. WATER QUANTITY CONCLUSION IT IS THE OPINION OF THE ENGINEER THAT BECAUSE THE 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.

LEVEL SPREADER Colt fag SL OPE L EGEN D PRESERVED SLOPES MANAGED SLOPES This is a revision to the approved POI 11 on WP0201800051, which showed 5.95 allowed and 4.54 dev. Plan WP0201800080 for Block 8B, currently under review, was using this 5.95 allowed number. WP0201800080 proposed an additional 0.83 CFS, which was allowed based on the approved numbers (4.54+0.83=5.37 which is less than 5.95 allowed). This plan shows 4.82 Dev, and if 0.83 is added to that it will be greater than the new allowed 5.49. It appears this plan includes the additional 0.83 that was added in WP020180080. Therefore, 0.83 would not have to be added. Please clarify and call with any questions. We suggest a note that says this plan incorporates WP0201800080's proposed drainage (if that is the case). 150 75 37.5 0 150 1 "=150' U ~ 0W o HU)i z o� oz ~j C) zU JOLL zw !G =oQL�w Kw Q Q Z a Q m W o J a J �� axraoa �o zQ0 'tUaF-Us =w U) LU woz L 3 W zQ� �o J Z W <� oz 0 Z a a 0 w a- z W Z� aax �za o0 Zwv >WLUj 00 �w> w� JUr a� Wz z> ow wxO Og<w w U) Qz� 0z=8)x 2Z =O81w a000wz UW zo JlnOf m<nzU ZQ♦- ♦.....♦ aN of Z QOLu Y - O 0 a <g U O of a o w z o W} c =< O W¢ a 2 z U) w x (n Z0 Of W d o0 U' W W U` U w z Z 0 Q W O"'.

FOR BLOCK 8A, 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, 0.68 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 BMPs 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. WITH THE AREAS AND LAND COVERS NOTED ABOVE THE TOTAL PHOSPHORUS LOAD REDUCTION REQUIRED FOR THIS LAND DISTURBING ACTIVITY IS 5.72 LB/YEAR. THE BMP MEASURES NOTED ABOVE ARE ABLE TO ACHIEVE A PHOSPHORUS LOAD REDUCTION OF 5.71 LB/YEAR WHICH IS WITHIN 0.005 LB/YEAR OF THE REQUIRED AMOUNT, WHICH IS CONSIDERED ACCEPTABLE BY 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.
