THE PROPOSED PLAN COMPLIES WITH PART IIB REQUIREMENTS. STORMWATER QUANTITY: CHANNEL PROTECTION IS MET THROUGH 9VAC25-870-66, SUBSECTIONS B.s.a AND B.4.a. FLOOD PROTECTION IS MET THROUGH 9VAC25-870-66, SUBSECTIONS C.2.a AND C.3.a. THE PROPOSED DEVELOPMENT OUTFALLS IMMEDIATELY UPLAND OF AN EXISTING CHANNEL. THE PROPOSED PLAN PROVIDES THREE ARMORED RIPRAP LINED OUTLET PROTECTIONS THAT ACCEPT RUNOFF FROM THE PROPOSED DEVELOPMENT. TWO OF THE THREE OUTLET PROTECTIONS RELEASE RUNOFF IMMEDIATELY UPLAND OF THE CHANNEL, ONE OF THE THREE OUTLET PROTECTIONS RELEASES RUNOFF INTO A RIPRAP LINED ADEQUATE CHANNEL, THAT THEN OUTFALLS IMMEDIATELY UPLAND OF THE CHANNEL. CALCULATIONS HAVE BEEN PROVIDED THAT SHOW THE OUTLET PROTECTIONS & THE RIPRAP LINED CHANNEL ARE NONEROSIVE DURING THE 2 -YEAR DESIGN STORM AND ITS BANKS ARE NOT OVERTOPPED DURING THE io-YEAR DESIGN STORM FOR THE CHANNEL, THE OUTLETS ARE DIRECTLY UPLAND OF PARROT BRANCH, WHERE THE SITE's AREAS ARE LESS THAN 1% OF THE STREAM'S CONTRIBUTING WATERSHED. SEE THIS PLAN, AND THE ACCOMPANYING STORMWATER MANAGEMENT CALCULATIONS PACKET, FOR DETAILS. STORMWATER QUALITY: THE STORMWATER QUALITY TREATMENT FOR THIS DEVELOPMENT IS PROVIDED VIA THE IMPLEMENTATION OF TWO BEST MANAGEMENT PRACTICES. THE BEST MANAGEMENT PRACTICE OF PROTECTING FOREST & OPEN SPACES FROM DISTURBANCES IS UTILIZED. A PROPOSED SWM FOREST AND OPEN SPACE EASEMENT WILL BE RECORDED WITH THIS DEVELOPMENT's PLAT. AFTER THE USE OF THIS BMP A FINAL PHOSPHOROUS REMOVAL OF 2.39 lbs/yr. IS REQUIRED. PHOSPHOROUS REMOVAL CREDITS WILL BE PURCHASED FOR THIS REMAINING BALANCE, ACHIEVING COMPLIANCE WITH PART Iib WATER QUALITY REQUIREMENTS. PLEASE SEE THE ATTACHED STORMWATER MANAGEMENT CALCULATIONS PACKET FOR ADDITIONAL DETAILS. &T1tlt 1S94AD W 11 VI e I'D OUTLET PROTECTION RIPRAP APRON/ CHANNEL DESIGN: 1.

THE SITE CURRENTLY CONTAINS A 2 -STORY DWELLING, A POOL, MUL77PLE SHEDS/BARNS, FENCING AND ANIMAL PASTURES. THE PARROT BRANCH STREAM RUNS ALONG THE PROPERTY ON THE NORTHSIDE. THE WEST AND SOUTH SIDES OF THE PROPERTY ARE BORDERED BY PARKVIEW DRIVE, AND THE EAST SIDE IS BORDERED BY A STREAM AND ITS BUFFER LOCATED ON TMP 56-67B. THE SITE IS GENERALLY WELL DRAINED WITH LIMITED PRESERVED AND MANAGED STEEP SLOPES.

CONTRACTOR SHALL IDEN77FY THE LIMITS OF DISTURBANCE AND INSTALL TREE PROTECTION FENCING WHERE INDICATED ON THE PLANS BEFORE ANY S17E DISTURBANCE SHALL TAKE PLACE. CONTRACTOR SHALL ENSURE THAT TREES TO BE SAVED ARE FLAGGED ALONG THE LIMITS OF CLEARING AND ARE PROTECTED. 4. UTILIZE THE EXIS77NG DRIVEWAY FOR THE CONSTRUCTION EN7RANCE AND MAKE ANY MODIFICATIONS NECESSARY. 774E CONSTRUC77ON ENTRANCE IS TO BE INSTALLED WHERE CONSTRUCTION VEHICLE ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY (VEHICULAR) TRACKING ONTO THE PAVED SURFACE.

MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE ACTIVITY AND SHALL BE MADE FUNC77ONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. 6. INSTALL ANY REMAINING EROSION CONTROL ITEMS AS SHOWN ON THE PHASE I EROSION CONTROL PLAN. 7 ONCE ALL THE PHASE l EROSION CONTROL 17EMS HAVE BEEN INSTALLED & ARE OPERATIONAL, DRAINAGE IS PROPERLY CONVEYED TO THESE MEASURES, AND THE ESC INSPECTOR HAS GRANTED APPROVAL, THE CONTRACTOR CAN BEGIN CLEARING THE SITE. 8. AFTER CLEARING THE PROPOSED AREAS, THE CONTRACTOR CAN FINISH ANY ROUGH GRADING OF THE SITE TO THE CONTOURS SHOWN ON THE PHASE I EROSION CONTROL PLAN. 9. PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN 7 DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN 7 DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT (UNDISTURBED) FOR LONGER THAN 14 DAYS. PERMANENT STABILIZA77ON SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR. 10. AFTER ALL PHASE ! ESC MEASURES ARE INSTALLED, 7HE CONTRACTOR CAN INSTALL THE CONSTRUCTION MEASURES AS SHOWN ON THE PHASE H EROSION CONTROL PLAN SHEETS. THIS INCLUDES THE RELOCATION OF THE CONSTRUCTION ENTRANCE TO THE ENTRANCE OF SNAPDRAGON LANE ONCE ROUGH GRADES ARE ACHIEVED FOR THIS. MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE AC77VITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. 11. THE CONTRACTOR SHALL THEN INSTALL THE UTILITIES, CURB AND GUTTER, ROADS AND PARKING LOTS THE CON7RACTOR SHALL COORDINATE CLOSELY WITH VDOT FOR THE IMPROVEMENTS TO PARKVIEW DRIVE. CULVERT INLET PROTECT70N SHALL BE INSPECTED AFTER EACH RAINFALL EVENT AND REPAIRS SHALL BE MADE AS NEEDED. IF THE STONE FILTER BECOMES CLOGGED WITH SEDIMENT SO THAT IT NO LONGER ADEQUATELY PERFORMS ITS FUNCTION, THE STONE MUST BE PULLED AWAY AND CLEANED AND/OR REPLACED. 14. INSTALL ANY REMAINING EROSION CONTROL ITEMS AS SHOWN ON THE PHASE H EROSION CONTROL PLAN. 15. ONCE THE SITE HAS BEEN GRADED AND STABILIZED TO THE POINT WHERE SEDIMENT TRAP #1 NEEDS TO BE FILLED, THE CONTRACTOR SHALL REQUEST AND OBTAIN APPROVAL FROM THE ESC INSPECTOR TO REMOVE SEDIMENT TRAP #1. SEDIMENT TRAP #1 SHALL BE PROPERLY DEWA7FRED AND FILLED, BUT ONLY AFTER THE INSPECTOR's APPROVAL. THIS TRIANGULAR AREA WILL BE GRADED WITH POSITIVE SLOPE WHILE IT /S BEING FILLED AND MAY REQUIRE THE REMOVAL OF ADJACENT TREES OUTSIDE OF THE STREAM BUFFER AND TREE PR07ECTION AREA. 16. SEDIMENT TRAPS #6 & #7 SHALL REMAIN IN PLACE UNTIL ALL UPLAND AREAS HAVE BEEN CONSTRUCTED AND STABILIZED, WITH THE EXCEPTION OF BUILDINGS 116, #7, & #11. ONCE THE UPLAND AREAS HAVE BEEN CONS7RUC7ED AND STABILIZED, THE CONTRACTOR SHALL REQUEST AND OBTAIN APPROVAL FROM THE ESC INSPECTOR TO REMOVE SEDIMENTS TRAP #6 & #7. SEDIMENT TRAPS #6 & #7 SHALL BE PROPERLY DEWATERED AND FILLED, BUT ONLY AFTER THE INSPECTOR's APPROVAL. 17. ONCE PHASE H OF CONSTRUCTION IS COMPLETE, THE SITE IS STABILIZED AND THE INSPECTOR HAS GIVEN APPROVAL, THE CONTRACTOR CAN REMOVE THE REMAINING EROSION &SEDIMENT CONTROL MEASURES INCLUSIVE OF THE PARKVIEW DRIVE 4 PROPOSED SEDIMENT TRAPS NO ITEM SHALL BE REMOVED UNLESS THE UPSTREAM AREAS ARE STABILIZED AND THE INSPECTOR GIVES PERMISSION. PLASTIC COVERS OVER ALL YARD DRAIN INLETS SHALL REMAIN ON UNTIL THE YARD DRAINS ARE LI VE/ACTTVA TED. 18. MAINTAIN ALL EROSION CONTROL MEASURES AS SPECIFIED IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, REMOVING ONLY WHEN APPROVED BY THE LOCAL PROGRAM ADMINISTRATOR IN ACCORDANCE NTH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. 19. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS :AFTER FINAL SITE STABILIZATION OR AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE LOCAL PROGRAM ADMINISTRATOR. TRAPPED SEDIMENT AND THE DISTURBED SOIL AREAS RESULTING FROM THE DISPOSITION OF TEMPORARY MEASURES SHALL BE PERMANENTLY STABILIZED TO PREVENT FURTHER EROSION AND SEDIMENTATION.
