4.4 EVALUATION OF PERFORMANCE OF DETENTION PONDS FOR <br />DEVELOPED CONDITIONS <br />With the hydrologic analysis of each of the drainage <br />areas now complete, the peak off site discharge at the <br />two outfall locations can be determined. For the <br />northwest drainage basin described in Section 4.O.A., <br />the north detention pond is the only discharge point for <br />storm runoff. Table 11 summarizes the peak rate of <br />discharge for the north detention pond and offers a <br />comparison with the pre -developed peak runoff rate <br />determined in Section 4.0 of this report. <br />TABLE 11 <br />COMPARISON OF PEAK RUNOFF RATES FOR THE <br />NORTHWEST DRAINAGE BASIN OUTFALL LOCATION <br />FOR PRE -DEVELOPED AND DEVELOPED CONDITIONS <br />PRECIPITATION PRE-DEVELOPEDEVENT PEAK FLOW RATE DEVELOPED <br />PEAK FLOW RATE <br />10YR-24HR 2.4 CFS <br />25YR-24HR <br />28 <br />1.9 CFS <br />
