STORMWATER MANAGEMENT NARRATIVE: OVERVIEW THIS PROJECT PROVIDES STORMWATER MANAGEMENT SWM PRACTICES TO MITIGATE THE IMPACTS FROM THE PROPOSED IMPROVEMENTS. THIS STORMWATER MANAGEMENT PLAN COMPLIES WITH PART IIB SWIM REQUIREMENTS. WATER QUALITY SUMMARY THE STORMWATER QUALITY REQUIREMENTS FOR THIS DEVELOPMENT ARE MET THROUGH THE BEST MANAGEMENT PRACTICE OF PURCHASING NUTRIENT CREDITS. A MINIMUM PHOSPHOROUS REMOVAL RATE OF 1.03 Ibs/yr IS REQUIRED. THE DEVELOPER WILL PURCHASE NUTRIENT CREDITS PRIOR TO THE ISSUANCE OF A LAND DISTURBANCE PERMIT. PLEASE SEE THE ATTACHED CALCULATIONS PACKET AND THIS SHEET FOR ADDITIONAL DETAILS. WATER QUANTITY SUMMARY THE PROPOSED DEVELOPMENT HAS ONE CONCENTRATED OUTFALL. THIS OUTFALL IS DIRECTED INTO A MANMADE STORM SEWER INLET LOCATED ON SEMINOLE TRAIL. ITS DRAINAGE AREA (SUBAREAS A & B) MEETS MINIMUM CHANNEL AND FLOOD PROTECTION REQUIREMENTS SET FORTH IN 9 VAC 25-870-66. SUBAREA A RECEIVES ATTENUATION VIA UNDERGROUND DETENTION SYSTEM 'A' INITIALLY, AND IS THEN DIRECTED INTO DETENTION BASIN 'B'. SUBAREA B's INFLOWS AND SUBAREA A's ROUTED OUTFLOWS WERE SYNCHRONIZED. THE SYNCHRONIZED STORM EVENTS WERE THEN ROUTED THROUGH DETENTION BASIN 'B'. THE RESULTANT DETENTION BASIN 'B' ROUTED OUTFLOWS ARE COMPLIANT WITH MINIMUM COUNTY & STATE REQUIREMENTS. IN SUMMARY, CHANNEL PROTECTION FOR SUBAREAS A & B IS MET THROUGH 9VAC25-870-66 SECTION B.3.a (ENERGY BALANCE) AND FLOOD PROTECTION IS MET THROUGH 9VAC25-870-66 SECTION C.2.b. (SOyr. POST FLOW < SO yr. PRE FLOW). COMPLIANCE WITH THESE SECTIONS IS ACHIEVED PRIMARILY THROUGH THE PROPOSED UNDERGROUND DETENTION SYSTEM 'A', THE PROPOSED DETENTION BASIN 'B' AND THE REDUCTION OF RUNOFF EXITING THE PROPERTY UNDETAINED.

THE DETENTION BASIN MAY SERVE AS A SEDIMENT BASIN AND/OR TRAP DURING PROJECT CONSTRUCTION. IF THIS IS DONE, THE VOLUME SHALL BE BASED ON THE MORE STRINGENT SIZING RULE (EROSION AND SEDIMENT CONTROL REQUIREMENTS VS. STORMWATER TREATMENT REQUIREMENTS). INSTALLATION OF THE PERMANENT RISER SHALL BE INITIATED DURING THE CONSTRUCTION PHASE, AND DESIGN ELEVATIONS SHALL BE SET WITH FINAL CLEANOUT OF THE SEDIMENT BASIN AND CONVERSION TO THE POST -CONSTRUCTION FACILITY IN MIND. APPROPRIATE PROCEDURES SHALL BE IMPLEMENTED TO PREVENT DISCHARGE OF TURBULENT WATERS WHEN THE BASIN IS BEING CONVERTED TO AN DETENTION BASIN. 2. THE DETENTION BASIN SHALL ONLY BE CONSTRUCTED AFTER THE CONTRIBUTING DRAINAGE AREA TO THE FACILITY IS COMPLETELY STABILIZED. IF THE SITE OF THE PROPOSED SWM FACILITY WILL BE USED AS A SEDIMENTTRAP OR BASIN DURING THE CONSTRUCTION PHASE, THEN THE FACILITY WILL BE DEWATERED, DREDGED AND RE -GRADED TO DESIGN DIMENSIONS AFTER THE ORIGINAL SITE CONSTRUCTION IS COMPLETE. MODIFICATIONS SHALL BE MADE TO THE RISER, ORIFICES AND BARRELS AS REQUIRED SO THAT THEY ARE C3 CONSISTENT WITH THE FINAL CONSTRUCTION SPECIFICATIONS. N N fV 3. THE CONTRACTOR SHALL ASSEMBLE CONSTRUCTION MATERIALS ON -SITE, MAKING SURE THEY MEET DESIGN SPECIFICATIONS AND ARE PREPARED AT STAGING AREAS WHEN POSSIBLE. n w m N 4. THE CONTRACTOR SHALL CLEAR AND STRIP THE PROJECT AREA IF REQUIRED TO THE DESIRED SUB -GRADE. � � c 5. INSTALL E&S CONTROLS PRIOR TO CONSTRUCTION OF THE BASIN, INCLUDING TEMPORARY DE -WATERING DEVICES AND STORMWATER DIVERSION PRACTICES. ALL AREAS P` a' SURROUNDING THE BASIN THAT ARE GRADED OR DENUDED DURING CONSTRUCTION SHALL BE PLANTED WITH TURF GRASS, NATIVE PLANTINGS, OR OTHER APPROVED METHODS OF SOIL STABILIZATION. 6. CONTRACTOR SHALL EXCAVATE THE CORE TRENCH AND INSTALLTHE SPILLWAY PIPE DURING THE ESC PHASE. 7. CONTRACTOR SHALL ALSO INSTALL THE RISER, OUTFLOW STRUCTURE AND/OR THE BARREL(s) WITH PERMANENT COLLARS DURING THE ESC PHASE TO ENSURE THE TOP INVERT OF THE OVERFLOW WEIR IS CONSTRUCTED LEVEL AT THE DESIGN ELEVATION. 8. THE CONTRACTOR SHALL CONSTRUCT THE EMBANKMENT AND ANY INTERNAL BERMS IN 8-TO 12-INCH LIFTS, COMPACTION SHALL BE COMPLETED IN LIFTS WITH APPROPRIATE EQUIPMENT.

CONTRACTOR SHALL THEN CONSTRUCTTHE EMERGENCY SPILLWAY IN CUT OR STRUCTURALLY STABILIZED SOILS. 11. THE CONTRACTOR SHALL THEN FINISH CONSTRUCTION OF ALL OUTLET STRUCTURES INCLUDING DOWNSTREAM RIP -RAP APRON PROTECTION. 12. THE CONTRACTOR SHALL NEXT STABILIZE EXPOSED SOILS BY HYDROSEEDING OR SEEDING OVER STRAW. 13. THE CONTRACTOR SHALL THEN INSTALL THE APPROPRIATE BASIN LANDSCAPING IN ACCORDANCE WITH THE APPROVED PLANS. FACILITY MAINTENANCE: MAINTENANCE OF THE DETENTION BASIN IS DRIVEN BY ANNUAL INSPECTIONS THAT EVALUATE THE CONDITION AND PERFORMANCE OF THE FACILITIES. DURING THESE INSPECTIONS THE FOLLOWING TASKS SHALL BE PERFORMED BY THE CONTRACTOR IN THE FIRST YEAR FOLLOWING INSTALLATION, AND THE OWNER THEREAFTER: 1. MEASURE SEDIMENT ACCUMULATION LEVELS IN THE BASIN. 2. MONITOR THE GROWTH OF THE GROUNDCOVER AND ANYTREES AND SHRUBS PLANTED AS APPLICABLE. RECORD THE SPECIES AND THEIR APPROXIMATE COVERAGE AND NOTE THE PRESENCE OF ANY INVASIVE PLANT SPECIES, AS APPLICABLE. 3. INSPECT THE CONDITION OF STORMWATER INLETS TO THE BASIN FOR MATERIAL DAMAGE, EROSION OR UNDERCUTTING. 4. INSPECT THE BANKS OF UPSTREAM AND DOWNSTREAM CHANNELS, IF APPLICABLE, FOR EVIDENCE OF SLOUGHING, ANIMAL BURROWS, BOGGY AREAS, WOODY GROWTH, OR GULLY EROSION THAT MAY UNDERMINE EMBANKMENT INTEGRITY. 5. INSPECT BASIN OUTFALL CHANNEL, IF APPLICABLE, FOR EROSION, UNDERCUTTING, RIP -RAP DISPLACEMENT, WOODY GROWTH, etc. 6. INSPECT CONDITION OF PRINCIPAL SPILLWAY AND RISER FOR EVIDENCE OF SPALLING JOINT FAILURE LEAKAGE CORROSION OR OTHER FAILURES. 7. INSPECT CONDITION OF ALLTRASH RACKS REVERSE SLOPED PIPES OR FLASHBOARD RISERS FOR EVIDENCE OF CLOGGING LEAKAGE DEBRIS ACCUMULATION OR OTHER FAILURES. B. INSPECT MAINTENANCE ACCESS TO ENSURE IT IS FREE OF WOODY VEGETATION, AND CHECK TO SEE WHETHER VALVES, MANHOLES AND LOCKS CAN BE OPENED AND OPERATED. 9. INSPECT INTERNAL AND EXTERNAL SIDE SLOPES OF THE BASIN FOR EVIDENCE OF SPARSE VEGETATIVE COVER, EROSION, OR SLUMPING. 10. OWNER OR CONTRACTOR SHALL MAKE NEEDED REPAIRS IMMEDIATELY. FACILITY INSPECTION: MULTIPLE INSPECTIONS ARE CRITICAL TO ENSURE THE BASIN s ARE PROPERLY CONSTRUCTED. BECAUSE THE TIMING OF THE INSTALLATION IS DICTATED BY THE CONTRACTOR THE CONTRACTOR SHALL BE RESPONSIBLE FOR CONTACTING THE ENGINEER AND INSPECTOR PRIOR TO INSTALLATION. MULTIPLE SITE VISITS AND INSPECTIONS ARE REQUIRED TO BE SCHEDULED BY THE CONTRACTOR WITH THE ENGINEER AND INSPECTOR DURING THE FOLLOWING STAGES OF THE DETENTION BASIN's CONSTRUCTION PROCESS: 1. PRE -CONSTRUCTION MEETING 2. INITIAL SITE PREPARATION INCLUDING INSTALLATION OF PROJECT E&S CONTROLS 3. EXCAVATION/GRADING (e.g., INTERIM/FINAL ELEVATIONS) 4.
