B. EXCAVATED MATERIAL SHALL BE PLACED ON THE UPHILL SIDE OF TRENCHES. C. EFFLUENT FROM DEWATERING OPERATIONS SHALL BE FILTERED OR PASSED THROUGH AN APPROVED SEDIMENT TRAPPING DEVICE, OR BOTH, AND DISCHARGED IN A MANNER THAT DOES NOT ADVERSELY AFFECT FLOWING STREAMS OR OFF -SITE PROPERTY. D. MATERIAL USED FOR BACKFILLING TRENCHES SHALL BE PROPERLY COMPACTED IN ORDER TO MINIMIZE EROSION AND PROMOTE STABILIZATION. E. RESTABILIZATION SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THIS CHAPTER. F. APPLICABLE SAFETY REQUIREMENTS SHALL BE COMPLIED WITH. 17. WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED OR PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PAVED OR PUBLIC ROAD SURFACE, THE ROAD SURFACE SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER. THIS PROVISION SHALL APPLY TO INDIVIDUAL DEVELOPMENT LOTS AS WELL AS TO LARGER LAND -DISTURBING ACTIVITIES. 18. 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 VESCP AUTHORITY.

THERE WILL BE AN INCREASE IN IMPERVIOUS AREA OF 0.30 AC AND AN INCREASE IN MANAGED TURF BY 0.12 AC. THE REMAINDER OF THE SITE WILL STAY WOODED. THERE IS A 20' UNDISTURBED BUFFER AROUND THE NORTH AND WEST SITE PERIMETER. THE SITE IS CURRENTLY VACANT AND IS PREDOMINANTLY WOODED. THE SITE HAS ROAD FRONTAGE ON GREENBRIER DRIVE (ROUTE 866) AND COMMONWEALTH DRIVE (ROUTE 852). THERE IS AN EXISTING CONCRETE SIDEWALK ALONG COMMONWEALTH. THE SITE IS CHARACTERIZED BY STEEP SLOPES (MANAGED SLOPES) AND DRAINS VIA SHEET FLOW AND SHALLOW CONCENTRATED FLOW TO A LOW OUTFALL AREA AT THE SOUTHERN EDGE OF THE SITE. THE OUTFALL AREA IS THE BACKWATER TO AN EXISTING CULVERT THAT CROSSES UNDER COMMONWEALTH DRIVE. AFTER DEVELOPMENT, THE DEVELOPED PORTION OF THE SITE WILL DRAIN TO A 96'-DIA DETENTION PIPE THAT WILL BE PRIVATELY OWNED AND MAINTAINED. A WEIR WALL IN THE DETENTION PIPE WILL CONTROL THE OUTFALL RATE INTO A 15"-DIA STORM SEWER PIPE. THE PIPE OUTFALL WILL TERMINATE IN A SECTION OF PERFORATED 15"PIPE BURIED IN A 4'-WIDE X S DEEP GRAVEL TRENCH. ONCE THE TRENCH FILLS WITH RUNOFF, IT WILL OVERFLOW A LEVEL LIP AND PROCEED VIA SHEET FLOW TO THE EXISTING 36"CULVERT THAT LEADS UNDER COMMONWEALTH DRIVE TOWARD THE EAST. THE REMAINDER OF THE SITE THAT IS NOT DETAINED WILL LEAVE THE SITE VIA SHEET FLOW. MAINTENANCE GUIDELINES FOR THE DETENTION PIPE AND LEVEL SPREADER ARE INCLUDED WITH THIS PLAN SET. NOTE THAT ALL HYDROLOGIC/HYDRAULIC CALCULATIONS ARE INCLUDED AS A SEPARATE BOOKLET THAT IS PART OF THE FINAL SITE PLAN/VSMP PLAN SUBMISSION. WATER QUANTITY CONTROL CHANNEL PROTECTION CHANNEL PROTECTION IS PROVIDED IN ACCORDANCE WITH 9VAC25-870-66 (B)lb AND (B)3, WHICH STIPULATE THAT THE MAXIMUM PEAK FLOW RATE FROM THE ONE-YEAR 24-HOUR STORM SHALL BE CALCULATED USING THE "ENERGY BALANCE" FORMULA. THE SITE COMPLIES WITH THIS CRITERIA. REFER TO THE ENERGY BALANCE CALCULATIONS ON THIS SHEET. CHANNEL PROTECTION RUNOFF SUMMARY MAXIMUM ALLOWED ONE-YEAR 24-HOUR PEAK FLOWRATE FROM THE SITE = 0.06 CFS ONE-YEAR 24-HOUR PEAK FLOWRATE = 0.01 CFS CHANNEL PROTECTION IS MET SINCE 0.01 CFS IS LESS THAN 0.06 CFS FLOOD PROTECTION FLOOD PROTECTION IS PROVIDED IN ACCORDANCE WITH 9VAC25-870-66 (C)2b, WHICH REQUIRES THAT THE PEAK FLOW RATE FROM THE 10-YEAR 24-HOUR STORM IS LESS THAN THE PEAK RATE FROM THE PREDEVELOPMENT 10-YEAR 24-HOUR STORM. THE SWM SYSTEM WAS MODELED IN A BACKWATER CONDITION DUE TO THE EXISTING 36" CULVERT UNDER COMMONWEALTH. REFER TO AREA MAP AND CULVERT CALCULATIONS ON THIS SHEET. FLOOD PROTECTION RUNOFF SUMMARY: PREDEVELOPMENT 10-YEAR 24-HOUR PEAK FLOWRATE = 1.99 CFS POSTDEVELOPMENT 10-YEAR 24-HOUR PEAK FLOWRATE = 1.96 CFS FLOOD PROTECTION IS MET SINCE 1.96 CFS IS LESS THAN 1.99 CFS NOTE THAT THE UNDETAINED RUNOFF CONTINUES LEAVES THE SITE VIA SHEET FLOW AND IS THEREFORE NOT INCLUDED IN THE POSTDEVELOPMENT FLOWRATE TOTALS.

VA 22963 Re: Nutrient Credit Availability - Greenbriar Office Building - Albemarle County Mr. Myers, The Virginia Nutrient Bank (VNB) is pleased to confirm availability of 0.56t pounds per year of phosphorus offsets (nutrient credits) for the Greenbriar Office Building site plan located at the SW intersection of Greenbrier Drive and Commonwealth Drive in Charlottesville. This project is located in HUC:02080204. VNB has approval from the Virginia Department of Environmental Quality (VDEQ) for Nonpoint Source Offset Generation Certification. VNB is approved to transfer nutrient credits in accordance with the Chesapeake Bay Watershed Nutrient Credit Exchange Program (VA Code 62.1-44.19:14 et seq). These offsets are also transferable in accordance with the Virginia stormwater offset program (VA Code 62.1- 44.15:35) and the Virginia Soil and Water Conservation Board's Guidance Document on Storntwater Nonpoint Nutrient Offsets approved on July 23, 2009. to those regulator entities qualifying for nutrient offsets. VNB is managing the Upper James Nutrient Bank in Nelson County that will generate approximately 155.31 pounds of phosphorus reduction and roughly 555.15 pounds of nitrogen reduction per year within the 02080203 HUC. VNB will retire 0. 61 pounds of phosphorus credits and corresponding nitrogen credits from the Upper .lames Nutrient Bank in accordance with the Nutrient Offset Certification regulations.
