Calculate Length: Bioswales Flow rate*540 seconds (9 minutes) For an unconnected bioswale, the fmow rate Calculate Flow Rate: (C*I*A) should be below 1 ft/s and the swale must be large enough to accommodate the 100 year I = inches per hour = 4 (North Carolina av) storm. Bioswales are usually trapezoidal, C = (.95*%impervious surface) + (.30*%pervious surface) with a minimum width of 4ft and a maximum A = area in acres (multiply SF by .000023) width of 8ft.
