Storm = 2.9 inches <br />Runoff = 1.89 inches <br />1.89 inches * 0.54 acres * 1 foot/12 inches = 0.085 Ac/ft <br />Containment Area Sizing <br />0.085 Ac/ft * 43,560 ft^2 = 3,705 Cubic feet of water <br />Acre <br />Runoff Volume 0.085 Ac/ft <br />Sediment storage <br />and Freeboard 0.267 Ac/ft <br />TOTAL c=> 0.352 Ac/ft <br />The containment area will be triangular in shape with 66 feat wide <br />by 186 feet long with an average depth of 2.5 feet for a total area <br />of 15,345 cubic feet. If topographical conditions are not suitable <br />for this configuration the pond will be configured to hold at least <br />0.2 Ac/ft as a minimum. <br />Ditch Sizing <br />All runoff that enters this pond is from direct runoff down the <br />side slopes and from direct precipitation. Ditches are not required <br />or present for this small area eximtion. <br />
