<br />S.O INSURANCE APPLICATION <br /> <br />, <br />are assigned to a community based on the results of the engineering <br />analyses. These zones are as follows: <br /> <br />Zone A <br /> <br />Zone A is the flood insurance rate zone that corresponds to the <br />100-year floodplains that are determined in the Flood Insurance <br />Study by approximate methods. Because detailed hydraulic analyses <br />are not performed for such areas, no base flood elevations or <br />depths are shown within this zone. <br /> <br />Zone AE <br /> <br />Zone AE is the flood insurance rate zone that corresponds to the <br />100-year floodplains that are determined in the Flood Insurance <br />Study by detailed methods. Whole-foot base flood elevations <br />derived from the detailed hydraulic analyses are shown at selected <br />intervals within this zone. <br /> <br />Zone AD <br /> <br />Zone AD is the flood insurance rate zone that cOI"responds to the <br />areas of 100-year shallow flooding (usually sheet flow on sloping <br />terrain) where average depths are between I and 3 feet. Average <br />whole-foot depths derived from the detailed hydraulic analyses are <br />shown within this zone. <br /> <br />Zone X <br /> <br />Zone X is the flood insurance rate zone that corresponds to areas <br />outside the SOD-year floodplain, areas within the SOD-year <br />floodplain, areas of 100-year flooding where average depths are <br />less than 1 foot, areas of 100-year flooding where the contributing <br />-dr'ainage area 'is-Tess than 1 squ-aremiTe, andareas-pr-6tected froiii-' <br />the IOO-year flood by levees. No base flood elevations or depths <br />are shown within this zone. <br /> <br />6.0 FLOOD INSURANCE RATE MAP <br /> <br />~ <br /> <br />The Flood Insurance <br />floodplain management <br /> <br />Rate Map is <br />applications. <br /> <br />designed <br /> <br />for <br /> <br />flood <br /> <br />insurance <br /> <br />and <br /> <br />For flood insurance applications, the map designates flood insurance <br />rate zones as described in Section S.O and, in the 100-year floodplains <br />that were studied by detailed methods, shows selected whole-foot base <br />flood elevations or average depths. Insurance agents use the zones and <br />base flood elevations in conjunction with information on structures and <br />their contents to assign premium rates for flood insurance policies. <br /> <br />34 <br />
