<br />5.0 INSURANCE APPLICATION <br /> <br />For flood insurance rating purposes, flood <br />are assigned to a community based on the <br />analyses. These zones are as follows: <br /> <br />insurance zone designations <br />results of the engineering <br /> <br />Zone A <br /> <br />Zone A is the flood insurance rate zone that corresponds to the <br />100-year floodplains determined in the Flood Insurance Study by <br />approximate methods. Because detailed hydraulic analyses are not <br />performed for such areas, no base flood elevations or depths are <br />shown within this zone. <br /> <br />Zone AE <br /> <br />Zone AE is the flood insurance rate zone that corresponds to the <br />lOa-year floodplains determined in the Flood Insurance Study by <br />detailed methods. In most instances, whole-foot base flood <br />elevations derived from the detailed hydraulic analyses are shown <br />at selected intervals within this zone. <br /> <br />Zone X <br /> <br />Zone X is the flood insurance rate zone that corresponds to areas <br />outside the SOO-year floodplain, areas within the SOO-year <br />floodplain, areas of lOa-year flooding where average depths are <br />less than 1 foot, areas of lOa-year flooding where the contributing <br />drainage area is less than 1 square mile, and areas protected from <br />the lOa-year flood by levees. No base flood elevations or depths <br />are shown within this zone. <br /> <br />Zone D <br /> <br />Zone D is the flood insurance rate zone that corresponds to <br />unstudied areas where flood hazards are undetermined, but possible. <br /> <br />6.0 FLOOD INSURANCE RATE MAP <br /> <br />The Flood Insurance Rate Map is designed for flood insurance and <br />floodpiain management applications. <br /> <br />For flood insurance applications, the map designates flood insurance rate <br />zones as described in Section 5.0 and, in the lOa-year floodplains that <br />were studied by detai led methods, shows selected whole-foot base flood <br />elevations or average depths. Insurance agents use the zones and base <br />flood elevations in conjunction with information on structures and their <br />contents to assign premium rates for flood insurance policies. <br /> <br />For floodplain management applications, the map shows by tints, screens, <br />and symbols, the lOO- and SOD-year floodplains, and the locations of <br />selected cross sections used in the hydraulic analysis. <br /> <br />13 <br />
