STORMWATER ON SITE IS ANALYZED AT FIVE DIFFERENT POINTS OF OUTLET. THE MAIN POINT OF ANALYSIS IS POA 1, WHERE A DETENTION POND COLLECTS RUNOFF AND RELEASES IT AT A RATE WHICH COMPLIES WITH CHANNEL PROTECTION REQUIREMENTS OF 9VAC25-870-66-B(3). THE RUNOFF FROM THIS DRAINAGE AREA IS RELEASED INTO A MAPPED FLOODPLAIN, MEETING FLOOD PROTECTION REQUIREMENTS. ALL OTHER DRAINAGE AREAS TO THE VARIOUS POINTS OF ANALYSIS MEET BOTH CHANNEL & FLOOD PROTECTION REQUIREMENTS AS THEY EITHER SATISFY THE ENERGY BALANCE EQUATION WITH AN IMPROVEMENT FACTOR OF 0.8 OR ARE RELEASED TO A MANMADE CONVEYANCE CHANNEL WITHOUT CAUSING EROSION OF THE SYSTEM, AND THEIR POST DEVELOPMENT 10 YR, 24 HR STORM PEAK FLOW RATE IS LESS THAN IN PRE DEVELOPMENT CONDITIONS. 2. WATER QUALITY WILL BE ADDRESSED BY PURCHASE OF 2.59 LBS NUTRIENT CREDITS TO MEET THE VRRM REDEVELOPMENT NUTRIENT REMOVAL REQUIREMENTS PER 9VAC25-870-63. 3. DETENTION POND COORDINATES: • (38.0355706,-78.4510122) MINIMUM STANDARDS (MS) All applicable Virginia Erosion and Sediment Control Regulations and Minimum Standards shall be adhered to during all phases of construction. These include, but are not limited to the following: STABILIZATION OF DENUDED AREAS: Permanent or temporary soil stabilization shall be applied to bare areas within seven days after final grade is reached on any portion of the site. Temporary soil stabilization shall be applied within seven days to denuded areas that may not be at final grade, but will remain dormant or undisturbed for longer than 14 days. Permanent stabilization shall be applied at areas that are to be left dormant for more than 1 year. 2. STABILIZATION OF SOIL STOCKPILES: During construction of the project, soil stockpiles shall be stabilized or protected with sediment trapping measures. The applicant is responsible for temporary protection and permanent stabilization of all soil stockpiles on site as well as soil intentionally transported from the project site. 3. PERMANENT VEGETATIVE COVER A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieve that, in the opinion of the county Inspector, is uniform and mature enough to survive to inhibit erosion. 4.TIMING & STABILIZATION OF SILT TRAPPING MEASURES: Sediment basins and traps, perimeter dikes, sediment barriers and other measures intended to trap sediment shall be constructed as a first step in any land disturbing activity and shall be made functional before upslope land disturbance takes place. 5. STABILIZATION OF EARTHEN STRUCTURES: Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions immediately after installation. 6. SEDIMENT TRAPS AND BASINS: A sediment basin shall control surface runoff from disturbed areas that is comprised of flow from drainage areas greater than or equal to three acres. The sediment basin shall be designed and constructed to accommodate the anticipated sediment loading for the land disturbing activity. The outfoll device or system device shall take into account the total drainage area flowing through the disturbed area to be served by the basin. 7. CUT AND FILL SLOPES: Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that are found to be eroding excessively within one year of permanent stabilization shall be provided with additional slope stabilizing measures until the problem is corrected. & CONCENTRATED RUN-OFF DOWN CUT OR FILL SLOPES: Concentrated runoff shall not flow down cut or fill slopes unless contained within an adequate temporary or permanent channel, flume, or slope drain structure. 9.WATER SEEPS FROM A SLOPE FACE: Whenever water seeps from a slope face, adequate drainage or other protection shall be provided. 10. STORM SEWER INLET PROTECTION: All storm sewer inlets that are made operable during construction shall be protected so that sediment -laden water cannot enter the conveyance system without first being filtered or otherwise treated to remove sediment. 11. STABILIZATION OF OUTLETS: Before newly constructed stormwater conveyance channels are made operational, adequate outlet protection and any required temporary or permanent channel lining shall be installed in both the conveyance channel and receiving channel. 12. WORK IN LIVE WATERCOURSES: When work in a live watercourse is performed, precautions shall be taken to minimize encroachment, control sediment transport and stabilize the work area to the greatest extent possible during construction. Nonerodible material shall be used for the construction of causeways and cofferdams. Earthen fill may be used for these structures if armored by nonerodible cover materials. 13.CROSSING A LIVE WATERCOURSE: When a live watercourse must be crossed by construction vehicles more than twice in any six month period, a temporary stream crossing constructed of nonerodible materials shall be provided. 14. APPLICABLE REGULATIONS: All applicable federal, state and local regulations pertaining to working in or crossing live watercourses shall be met. 15. STABILIZATION OF BED AND BANKS The bed and banks of a watercourse shall be stabilized immediately after work in the watercourse is completed. 16.UNDERGROUND UTILITIES: Underground utilities shall be installed in accordance with the following standards in addition to other criteria: a.No more than 500 linear feet of trench may be opened at one time. b.Excavated material shall be placed on the uphill side of trenches c.Effluent for dewatering operations shall be filtered or passed through approved sediment trapping device, or both, and discharged in a manner that does not adversely affect flowing streams or offsite 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 these regulations. f. Applicable safety regulations shall be complied with. 17.CONSTRUCTION ACCESS ROUTES: Where construction vehicle access routes intersect paved public roads, provisions shall be made to minimize the transport of sediment by vehicular tracking onto paved surfaces. Where sediment is transported on to a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed 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 lots as well as to larger land disturbing activities. 18.TEMPORARY E&S CONTROL MEASURE REMOVAL: All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or after temporary measures are no longer needed, unless otherwise authorized by the local program authority. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sediment. 19. ADEQUACY OF RECEIVING CHANNELS: Properties and waterways downstream from the development site shall be protected from sediment deposition, erosion and damage, due to increases in volume, velocity and peak flow rates of stormwater runoff for the stated frequency storm of 24-hour duration.

The drainage areas to points of analysis 1 thru 3 are separated into disturbed and undisturbed area, since the improvement factor is only applied to the disturbed portions. Points of analysis 4 and 5 include only disturbed area, since the disturbances create no change to the drainage patterns outside the limits of disturbance in those areas. Drainage areas to POA 1 are further separated into drainage to the existing detention system on site and drainage straight to POA 1. All end up at POA 1, but this separation was used to ensure that the existing detention system will continue to function as designed. The post -development drainage area acreage and curve number to the existing detention system are less than in pre -development conditions. Runoff to POA 1 is held in a detention pond and released at a peak flow rate that complies with channel protection requirements set forth in 9VAC25-870-66-B3 (energy balance equation). Flood protection is met as runoff is outlet into a mapped floodplain. Runoff to all other points of analysis complies with flood protection requirements as the post -development 10 yr, 24 hr storm is released at a peak flow rate less than in pre -development conditions. Channel protection requirements are met at all points of analysis. POA 1 - POA 4 are analyzed according to 9VAC25-870-66(B)(3). POA 5 is analyzed according to 9VAC25-870-66(B)(1)(a). \ i ;_ — t _ — T.M.78-9 T C � \3 � CO PARTNERS, LL D.B. 4710-713 _ �.... ------ I D.B. 3657 9 THRU 578 PLAT _ ■ __��_—_ - if ---- — �iiil D.B. 3339-701, jl I -_--- -- - - - _ _ \ 704 THRU 707 PLAT 0 - ` -_- - -400- A- ---_----- ZONED: HC I � I DEXISTIN DE�EfUTIIQNAREY": & PO/k'1 0.571 AC WITHIN LIMITS 11218�A caiDftfl1lT1 I \ I r VJ'F 6/CV VRHIIVHVF� 0.1231 AA, -,WITHIN LIN h Iv ry j OF DISTU, BANCE, CN = 95 e OF DIST RBANCE, CN = 9 1 \\ \ ll il�i L4i iiiirirai.r i..irri.r=,li,!• - i. .�.. - PORTION OF POSTDEV L DRAINAGE AREA TO POA 1 . � H S G B _ ------ 3 P ,� / ' OST � -T 0 III\ ------ EXISTING DETENTION'SYST�Tv1 _ _ 410— — e I O / II AW J // <� ( �' POSTDF'V DRAINAGE AREA TO POA 5 a I -- =, , 0.315 AC WITHIN LIMITS OF DISTURBANCE, CN T 93 1 ` TOC = 5 MINSi SUMMARY OF DRAINAGE AREAS DISTURBED AREA UNDISTURBEDAREA DA AREA (AC) CN AREA (AC) CN TO POA 1 DIRECTLY 3.13 89 0.692 58 TO EX DET PIPE, THEN POA1 0.571 98 1.238 95 TO POA 2 0.236 61 1.18 58 TO POA 3 0.123 95 1.506 97 TO POA 4 0.105 65 TO POA 5 1 0.3151 93 SUMMARY OF STORMWATER QUANTITY CALCULATIONS POA Q1 ALLOWABLE (cfs) Q1 PROPOSED (cfs) Q10 PRE (cfs) Q10 POST (cfs) 1 8.85 3.49 27.97 36.31* 2 1.73 0.49 7.29 3.74* 3 8.63 6.92 14.39 12.91 4 11.54 0.09 2.12 0.38 5 NA 1 1.221 2.671 2.41 *Discharges to Mapped Floodplain SHIMP ENGINEERING LAND PLANNING I SITE DESIGN I CIVIL ENGINEERING I PROJECT MANAGEMENT Design F1 used Engineering 912 East High Street Phone: 43 227-5140 Chanotlesville, VA 22902 shimp-angineanng.wm 1 / / VSMP PLAN / ALBEMARLE COUNTY, VIRGINIA 1300 RICHMOND / ROAD - FLOW - / AUTOMOTIVE Scale: 1 "=40' SUBMISSION: 2020.06.02 REVISION: 01) FILE NO. 19.078 POST DEVELOPMENT DRAINAGE MAP SHEET C13 OF 14 $° 12 C13 T.M. 78-58G1 PANTOPS CORNER LC.
