<br />cw(,~ <br /> <br />FOREWORD <br /> <br />This guide was developed for use by community officials, property <br />owners, developers, surveyors, and engineers who may need to <br />determine Base (lOo-year) Flood Elevations (BFEs) in special flood <br />hazard areas designated as approximate Zone A on the Federal <br />Emergency Management Agency's FloOd Insurance Rate Maps published <br />as part of the National Flood Insurance Program. One of the <br />primary goals of this document is to provide a means of determining <br />BFEs at a minimal cost. <br /> <br />The guidance provided herein is primarily intended for use in <br />riverine and lake areas where flow conditions are fairly uniform, <br />and do not involve unusual flow regimes (rapidly varying flow, two- <br />dimensional flow, supercritical flow, hydraulic jumps, etc.). <br /> <br />This guide is not to be used for areas that experience alluvial fan <br />flooding or areas that contain characteristics of alluvial fan <br />flooding. In addition, this guide is not to be used in Zone V <br />(velocity) areas or coastal Zone A areas that are subject to <br />flooding due to storm surge from hurricanes and other coastal <br />storms. Furthermore, guidance on determining regulatory floodways <br />is not provided in this guide. <br /> <br />, <br />c. <br />I <br />! <br />I <br />t <br />( <br />I <br />I <br />, <br />I <br />I <br />I <br />l <br />t <br />~ <br />, <br />, <br />t i <br />[- <br />I <br />t <br />, <br />I <br />I <br />! <br /> I <br /> ---^- <br />
