Exhibit <br />2-6, 2-7, and 2-8 shows locations of drainage and flooding problems defined by these <br />damage and flooding reports. <br /> <br />2.3.3 Subdivision Areas with Significant Drainage or Flooding Problems <br /> <br />Based upon the data gathered on drainage and flooding problem locations, general <br />locations (identified by subdivision areas) of significant drainage or flooding problems <br />were identified. These are listed in Table 2-2. <br /> <br />To assist in identifying the level of severity of the drainage and flooding problems in the <br />identified subdivision areas, each flood damage report (arising from Tropical Storm <br />Allison, Tropical Storm Erin, severe structural damage reports, and repetitive loss reports, <br />discussed above) was assigned a weighting factor (selected in consultation with City staff <br />and listed in Table 2-3) so that a severity index could be computed from the sum of the <br />weighted reports in the general vicinity of the subdivision where the flooding problem <br />was reported. The details of the process of generating this severity index are discussed at <br />length in Letter Report No.3. The computed severity index, termed the flood problem <br />"intensity" is listed in Table 2-4. <br /> <br />The computed flood problem intensities can be used to graphically display the severity of <br />flooding problems across the various watersheds, as illustrated in Exhibits 2-9, 2-10, and <br />2-11. Since the intensity values should be considered only as approximate, the exhibits <br />use only broad classifications to display the problem severities in various subdivision <br /> <br />areas. <br /> <br />Note that it is the relative magnitude of the flood problem intensity parameter that is of <br />importance, not its absolute magnitude. Consequently, for assistance in decision making <br />about remedies for drainage and flooding problems, the intensity values can be used to <br /> <br />2-7 <br /> <br />Klotz Associates Project No. 0] 27.008.000 <br />January 2009 <br /> <br />La Porte Citywide Drainage Study <br />City of La Porte <br />
