d <br />The longest flow path begins on the western end of the <br />basin where surface flow from the parking area is <br />directed into inlet structures. Flow is directed <br />northward through a series of storm drain pipes until <br />reaching the beginning of the biofiltration swale. <br />At this point runoff is conveyed through the swale <br />in a west/southwest direction until reaching the inlet of <br />the north detention basin. This point will serve as the <br />point of analysis for the generation of the peak flow <br />hydrograph for the northwest sub -basin area. The results <br />are listed in Tablc 4. <br />CTABLE 4 <br />PEAK DISCHARGE FOR NORTHWEST PARKING AREA, <br />(BASIN 1), FOR DEVELOPED CONDITIONS <br />PRECIPITATION EVENT <br />(FREQUENCY/DURATION) <br />25YR-24HR <br />15 <br />PEAK DISCHARGE <br />(CFS) <br />7.81 <br />h� <br />
