<br />the boundaries were interpolated using topographic maps at a scale of <br />1:24,000, with a contour interval of 2 feet. <br /> <br />The floodways presented in this study were computed on the basis of <br />equal-conveyance reduction from each side of the floodplain. The <br />results of these computations are tabulated at selected cross sections <br />for each stream segment for which a floodway is computed. <br /> <br />As part of this revision, the conversion of the FIRM for the <br />unincorporated areas of Summit County, Colorado, to the Map Initiatives <br />Format on a panel-to-panel basis was initiated. In the Map Initiatives <br />Format, all base flood elevations, cross sections, zone designations, <br />and floodplain and floodway boundary delineations are shown on the FIRM. <br />The flood insurance zone designations were changed to reflect the new <br />format. Areas previously shown as numbered Zone A were changed to Zone <br />AE, areas with base flood elevations determined. Areas previously shown <br />as Zone B were changed to Zone X (shaded), areas that would be inundated <br />by the flood having a 0.2-percent chance of being equaled or exceeded in <br />any given year. Areas previously shown as Zone C were changed to Zone X <br />(unshaded), areas outside the O.2-percent-annual-chance floodplain. In <br />addition, all zone designations and reach determinations were removed <br />from all Profile Panels, FIRM Panels 0106, 0107, 0108, 0109, 0117, <br />0184, 0192, and 0211 have been revised to reflect the new format, All <br />other FIRM panels within Summit County reflect the standard format, <br /> <br />Table 1, "Surrunary of Discharges," Table 2, "Floodway Data," and <br />Exhibit 1, "Flood Profiles," were revised as a result of the study. <br /> <br />40 <br />
