<br />5.0 INSURANCE APPLICATION <br /> <br />In order to establish actuarial insurance rates, the Federal Insurance <br />Administration has developed a process to transform the data from the <br />engineering study into flood insurance criteria. This process includes <br />the determination of reaches, Flood Hazard Factors, and flood insurance <br />zone designations for each flooding source studied in detail affecting <br />the Town of Redcliff. <br /> <br />5.1 Reach Determinations <br /> <br />Reaches are defined as lengths of watercourses having relatively the <br />Same flood hazard, based on the average weighted difference in <br />water-surface elevations between the 10- and lOO-year floods. This <br />difference does not have a variation greater than that indicated in <br />the following table for more than 20 percent of the reach: <br /> <br />Average Difference Between <br />10- and lOa-year Floods <br /> <br />variation <br /> <br />Less than 2 feet <br />2 to 7 feet <br />7.1 to 12 feet <br />More than 12 feet <br /> <br />o . 5 foot <br />L 0 foot <br />2,0 feet <br />3.0 feet <br /> <br />The locations of the reaches determined for the flooding sources of <br />the Town of Redcliff are shown on the Flood Profiles (Exhibit 1) and <br />summarized in Table 3. <br /> <br />5.2 Flood Hazard Factors <br /> <br />The Flood Hazard Factor (FHF) is the Federal Insurance Administration <br />device used to correlate flood information with insurance rate <br />tables. Correlations between property damage from floods and their <br />FHF are used to set actuarial insurance premium rate tables based on <br />FHFs from 005 to 200. <br /> <br />The FHF for a reach is the average weighted difference between the <br />10- and laO-year flood water-surface elevations expressed to the <br />nearest one-half foot, and shown as a three-digit code. For example, <br />if the difference between water-surface elevations of the 10- and <br />lOa-year floods is 0.7 foot, the FHF is 005; if the difference is <br />1.4 feet, the FHF is 015; if the difference is 5.0 feet, the FHF is <br />050. Wben the difference between the 10- and lOO-year water-surface <br />elevations is greater than 10.0 feet, accuracy for the FHF is to the <br />nearest foot. <br /> <br />12 <br />
