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 or equal to the average land covercondition (Iwatershed) and the proposed improvements will create a total percent impervious cover (Ipost) which is less than or equal to the average land cover condition (I watershed) Ipost Iwatershed Worksheet 1 Page 3 of 3 X Situation 2: This consists of land development where the existing percent impervious cover (lexisting) is less than or equal to the average land covercondition (Iwatershed) and the proposed improvements will create a total percent impervious cover (lp°st) which is greaterthan the average land cover condition (Iwatershed)• lexisting 0•� < Iwatershed 16% (post 43% > Iwatershed 16% Situation 3: This consists of land development where the existing percent impervious cover (lexisting) is greaterthan the average land covercondition (Iwatershed) lexistin¢ Iwatershed Situation 4: This consists of land development where the existing percent impervious cover(Iexst;ng) is served by an existing stormwater management BMP (s) that addresses water aual itv 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: Lpost = relativepost-development total phosphorus load (pounds per year) I 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 per year STEP 6 Determine the relative poluutant removal requirement (RR). RR = Lpost - Lpre(watershed) RR = 83.563 - 36.863 = 46.700 Pounds per year 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.
