Users should be aware that flood elevations shown <br /> on the Flood Insurance Rate Map (FIRM) represent rounded whole-foot <br /> elevations and may not exactly reflect the elevations shown on the Flood Profiles <br /> or in the Floodway Data Table in the FIS report. Flood elevations shown on the <br /> FIRM are primarily intended for flood insurance rating purposes. For <br /> construction and/or floodplain management purposes, users are cautioned to use <br /> the flood elevation data presented in this FIS report in conjunction with the data <br /> shown on the FIRM. <br /> Cross sections for the new, detailed backwater analyses of the Arkansas River and <br /> Wolf Creek within the Town of Granada; the Arkansas River and Wild Horse <br /> 10 <br />
