<br />year floodplain is divided into a floodway and a floodway fringe. <br />The floodway is the channel of a stream, plus any adjacent <br />floodplain areas, that must be kept free of encroachment so that <br />the lOO-year flood can be carried without substantial increases in <br />flood heights. <br /> <br />No floodways were computed for flooding sources studied by detailed <br />methods in the Town of Parachute due to floodway computations being <br />outside of the scope of work. <br /> <br />5.0 INSURANCE APPLICATIO~ <br /> <br />For flood insurance rating purposes, flood insurance zone designations <br />are assigned to a community based on the results of the engineering <br />analyses. These zones are as follows: <br /> <br />Zone AE <br /> <br />Zone AE is the flood insurance rate zone that corresponds to the <br />lOO-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 X <br /> <br />Zone X is the flood insurance rate zone that corresponds to areas <br />outside the 500-year floodplain, areas within the 500-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 />drainage area is less than 1 square mile, and areas protected from <br />the lOO-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 />The Flood Insurance Rate Map is designed for flood insurance and <br />floodplain management applications. <br /> <br />For flood insurance applications, the map designates flood insurance <br />rate zones as described in Section 5.0 and, 1n 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 />For floodplain management applications, the map shows by tints, screens, <br />and symbols, the lOO- and 500-year floodplains, floodways, and the <br />locations of selected cross sections used in the hydraulic analyses and <br />floodway computations. <br /> <br />9 <br />
