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-developme nt total phosphorus load (pounds per year) Ipost = 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. 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 enteringthe proposed BMP(s) : LBMP = [0.05+(0.009 x IBMP)] x A x 2.28 (Equation 5-23) Where: LBMP = relative post -development total phosphorus load entering proposed BMP (pounds per year) Ipost = post -development percent impervious cover of BMP drainage area percent expressed in whole numbers) A = Applicable area of proposed BMP (acres) LBMp, = (0.05+(0.009) x 43 )] x 21.60 x 2.28 = 21.516 Pounds per year LBMP2 = 10.05+(0.009) x 41 )] x 1.91 x 2.28 = 1.820 Pounds per year LBMP3 = [0.05 + (0.009) x 53 )] x 40.31 x 2.28 = 48.815 Pounds per year LBMP4 = [0.05 + (0.009) x 39 )] x 1.54 x 2.28 = 1.411 Pounds per year Water Quality Volume Calculations: Vwq (ft3)= Impervious area (ft) x 0.5 (in) / 12 (in./ft Vwq (ac.ft.) = Vwq (ft3) / 43560 ft'/ac.

Specific Facilities may require additional measures not discussed here. A schedule of recommended maintenance for bioretention areas is given in Table 3.11-5. The table gives general guidance regarding methods, frequency, and time of year for maintenance. Planting Soil Urban plant communities tend to become very acidic due to precipitation as well as the influences of storm water runoff. For this reason, it is recommended that the application of alkaline, such as limestone, be considered once to twice a year. Testing ofthe pH ofthe organic layer and soil, should precede the limestone application to determine the amount of limestone required. Soil testing should be conducted annually so that the accumulation of toxins and heavy metals can be detected or prevented. Over a period of time, heavy metals and other toxic substances will tend to accumulate in the soil and the plants. Data from other environs such as forest buffers and grass swales suggest accumulation of toxins and heavy metals within five years of installation. However, there is no methodology to estimate the level oftoxic materials in the bioretention areas since runoff, soil, and plant characteristics will vary from site to site. As IItoxicsubstancesaccumulate,theplantbiologicfunctionsmaybecomeimpaired,andtheplant rh experience dwarfed growth followed by mortality. The biota within the soil can also become void and the natural soil chemistry may be altered. The preventative measures would include the removal ofthe contaminated soil. ]n some cases, removal and disposal ofthe entire soil base as well as the plant material may be required. Mulch Bioretention areas should be mulched once the planting of trees and shrubs has occurred. Any ground cover specified as plugs may be installed once the area has been mulched. Ground cover established by seeding and\or consisting of grass should not be covered with mulch. GRAPHIC SCALE 20 40 ( IN FEET ) 1 inch = 20 ft. LEGEND P1NISH£D GRADE AT CIL - - - - - - - - - DOST.
