<br />4.2 Floodways <br /> <br />The floodway is the channel ofia stream, plus any adjacent flood <br />plain areas, that must be keptifree of encroachment so that the <br />100-year flood can be carried ~ithout substantial increases in <br />flood heights. Minimum Federal standards limit such increases to <br />1.0 footr provided that hazard9us velocities are not produced. <br /> <br />Floodways are not presented on <br />Chalk, and Cottonwood Creeks. <br />is not available. <br /> <br />the South Arkansas River or poncha, <br />Floodway information for these streams <br /> <br />5.0 INSURANCE APPLICATION <br /> <br />For flood insurance rating purposes, flood insurance zone designations <br />are assigned to a community based on, the results of the engineering analyses. <br />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 flood plains that arei 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 depths <br />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 flood plains that are! determined in the Flood Insurance <br />I <br />Study by detailed methods. Whole-foot base flood elevations derived <br />from the detailed hydraulic an~lyses are shown at selected intervals <br />within this zone. . <br /> <br />Zone AH <br /> <br />Zone AH is the flood insurance rate zone that corresponds to the <br />areas of 100-year shallow flooping (usually areas of ponding) where <br />average depths are between 1 apd 3 feet. Whole-foot base flood <br />elevations derived from the d~tailed hydraulic analyses are shown <br />at selected intervals within ~his zone. <br /> <br />Zone X <br /> <br />Zone X is the flood insurance .rate zone that corresponds to areas <br />outside the sOO-year flood pl~in, areas within the sOO-year flood <br />plain, areas of 100-year floo~ing where average depths are less <br />than 1 foot, areas of 100-yea~ flooding where the contributing <br /> <br />10 <br />
