THE EXISTING SITE IS HAS BEEN CLEARED AND GREADED WITH NORTH POINTE SUBDIVISION SECTION 1 . THE SITE SLOPES TO TIE EAST T TO A CULVERT THAT WAS PROPSOED WITH NORTH POINTE SUBDIVISION SECTION 1. ADJACENT AREAS THE SITE IS BORDERED BY THE ROADS THAT WERE PROPOSED WITH NORTH POINTE SECTION 1, ROCKY CREEK DRIVE, NORTHPOINT'E BOULEVARD AND NORTHFORK DRIVE TO NORTH WEST AND SOUTH AND IS BORDERED BY A RESIDENTIAL LOT PROPOSED WITH NORTHPOINTE SECTION 1 TO THE EAST. OFFSITE AREAS THERE IS NO OFFSITE WORK PROPOSED WITH THIS PROJECT. SOILS THE SITE IS CHARACTERIZED BY ELIOAK LOAM AND GLENELG LOAM. CRITICAL AREAS THIS SITE IS SET UP TO DRAIN TO A SEDIMENT TRAP WHICH WILL BE MAINTAINED UNTIL THE SITE IS STABILIZED. THE SITE CONTAINS STEEP SLOPES THROUGHOUT THE DISTURBED AREAS. THESE DISTURBED AREAS WILL NEED TO BE SEEDED AND STABILIZATION ACHIEVED TO PREVENT EROSION FROM OCCURRING AS THE WORK PROGRESSES. THE CONTRACTOR SHOULD ALSO TAKE CARE. TO KEEP CONSTRUCTION ENTRANCES IN GOOD WORKING CONDITION IN ORDER TO NOT TRACK MUD ONTO EXISTING ROADWAYS. EROSION AND SEDHOENT CONTROL MEASURES - PHASE I 1 - ALL EROSION AND SEDIMENT CONTROL MEASURES MUST BE INSTALLED, MAINTAINED AND REMOVED IN ACCORDANCE WITH THE CRITERIA AND GUIDELINES CONTAINED IN THE CURRENT EDITION OF THE VIRGINIA EROSION & SEDIMENT PERMANENT STABILIZATION THE CONTRACTOR SHALL PROVIDE GRASS STABILIZATION ON ALL DENUDED AREAS PRIOR TO TURNOVER OF THE PROJECT TO THE DEVELOPER.

Therefore, 5. Calculate the total pollutant load removed by the BMP(s): consult the locality for proper determination of this value. Lpre(watershed)=[0.05+(0.009xlwatershed)]xAx2.28 (Equation5-16) Lremoved/total = Lremoved/BMP3+Lremoved/BMP2+Lremoved/BMP3+Lremoved/BMP4 STEP 2 Determine the average land cover condition (Iwatershed) or the existing Where (.watershed) = relative pre -development total phosphorus load (pounds peryear) impervious I P (existing) Iwatershed = average land cover condition for specific watersh or locality or Lremoved/total= 13.99+ 0.91 + 31.73 + 0.71 the Chesapeake Bay default value of 16% (percent expressed in Average land cover condition (Iw„eRhed): whole numbers) = 47.33 Pounds peryear A = Applicable area (acres) If the locality has determined land cover conditions for individual watersheds within its 6.

Existing impervious cover: Structures = acres parking lot = acres roadway = acres other: Total = acres acres = acres I exiting =(total post -development impervious cover/A) x 101 0% * The area should be the same as used in STEP 1. STEP 3 Determine the appropriate situation. The site informtaion determined in STEP 1 and STEP 2 provide enough information to determine the appropriate development situation underwhich the performance criteria will apply. Check ( ) the appropriate development situation as follows: Situation 1: This consists of land development where the existing percent impervious cover (lexisting) is less than orequal to the average land cover condition (Iwatershed) and the proposed improvements will create a total percent impervious cover (IPost) which is less than orequal to the average land covercondition (Iwatershed) (post Iwatershed Worksheet 1 Page 3 of 3 X Situation 2: This consists of land development where the existing percent impervious cover (Ioxisting) is less than orequal to the average land covercondition (Iwatershed) and the proposed improvements will create a total percent impervious cover (lpost) which is greaterthan the average land cover condition (Iwatershed). lexisting 0% < Iwatershed 16% Ipost 43% > Iwatershed 16% Situation 3: This consists of land development where the existing percent impervious cover(lexisting)is greaterthan the average land covercondition (Iwatershed) lexisting lwatershed Situation 4: This consists of land development where the existing percent impervious cover (lexisting) is served by an existing stormwater management BMP (s) that addresses water quality If the proposed development meets the criteria for development Situation 1, than the low density development is considered to be the BMP and no pollutant removal is required. The calculation procedure for Situation 1 stops here. If the proposed development meets the criteria for development Situations 2, 3 or4, then proceed to STEP 4 on the appropriate worsheet. STEP 5 Determine the relative post -development pollutant load (Lpost). LPost = [0.05+(0.009 x Iwatershed)] x A x 2.28 (Equation 5-16) Where: Loos, = relativepost-development total phosphorus load (pounds peryear) (post = post -development percent impervious cover (expressed in whole numbers) A = Applicable area (acres) Lpost = [0.05 + (0.009) x 43% )] x 83.34 x 2.28 = 83.563 Pounds peryear STEP 6 Determine the relative poluutant removal requirement (RR). RR = Lpost - Lpre(watershed) RR = 83.563 - 36.863 46.700 Pounds peryear STEP 7 Identify best management practice (BMP) for the site. 1. Determine the required pollutant removal efficiency forthe site: EFF = ( RR / Lpost) x 100 Where: EFF = required pollutant removal efficiency (percent expressed in whole numbers) RR = pollutant removal requirement (pounds peryear) Lpost = relative post -development total phosphorus load (pounds per year) EFF = 46.700 / 83.563 x 100 = 56% 2. Select BMP (s) from Table 5-15 and locate on the site: BMP 1: BMP 2: BMP 3: BMP 4: BMP 5: 3. Determine the pollutant load entering the proposed BMP(s) LBMP = [0.05+(0.009x IBMP)] x A x 2.28 (Equation 5-23) Where: LBMP = relative post -development total phosphorus load entering proposed BMP (pounds peryear) (post = post -development percent impervious coverof BMP drainage area percent expressed in whole numbers) A = Applicable area of proposed BMP (acres) Lamp, = [0.05 + (0.009) x 43 )] x 21.60 x 2.28 = 21.516 Pounds peryear LBMP2 = [0.05 + (0.009) x 41 )] x 1.91 x 2.28 = 1.820 Pounds peryear 4MP3 = [0.05 + (0.009) x 53 )] x 40.31 x 2.28 = 48.815 Pounds peryear LBMP4 = [0.05 + (0.009) x 39 )] x 1.54 x 2.28 = 1.411 Pounds peryear Water Quality Volume Calculations: Vwq (ft)= Impervious area (ft) x 0.5 (in) / 12 (in./ft Vwq (ac.ft.) = Vwq (ft) / 43560 ftz/ac.
