Analvsis. For the area protected by a levee providing less <br />,,~, than lOO-year p"otecti()~, lOO-year flood elevations shall be <br />computed as if the levee did not exist. For the unprotected <br />area between the levee and the source of flooding, the <br />elevations to be shown shall be obtained from either the flood <br />.. profile that would exist at the time levee overtopping begins <br />or the profile computed as if the levee did not exist, <br />whichever is higher. - <br /> <br />This procedure recognizes the increase in flood elevation in <br />the unprotected area that is caused by the levee itself. This <br />procedure may result in flood elevations being shown as several <br />feet higher on one side of the levee than on the other. Both <br />profiles should be shown in the final report and labeled as <br />"before levee overtopping" and "after levee overtopping," <br />respectively. <br /> <br />,".', <br />"'; <br /> <br />, <br /> <br /> <br />.. <br /> <br />THE CODE OF COLORADO REGULATIONS <br /> <br />2 CCR 408.1 <br />
