WI <br />With the physical features of each basin area now <br />numerically defined, the "Runoff" block provided with the <br />SWMM program was used to generate runoff hydrographs for <br />each basin area under developed conditions. <br />4.2 RESULTS OF ANALYSIS FOR DEVELOPED CONDITIONS <br />The results of the hydrologic analysis performed for each <br />basin area are given in the following Sections 4.2A - <br />4.2C. The results obtained from the "Runoff" block <br />analysis producing the results in this section are given <br />in Appendices C - F. <br />A. EVALUATION OF NORTHWEST PARKING AREA, BASIN 1 <br />The northwest parking area, basin 1, shown an <br />Drawing No. SK-C2.0, is comprised of 10.42 acres. <br />Approximately 8.57 acres (82 percent) of the area is <br />covered with an impervious roof or pavement surfacing. <br />The remaining 1.85 acres is pervious cover located around <br />the biofiltration swale. <br />14 <br />
