<br />. . <br /> <br />E. LEVEE/FLOODWALL (CONTINUED) <br /> <br />7. Settlement <br /> <br />a. Has anticipated potential settlement been determined and incorporated into the specified construction elevations to maintain the <br />established freeboard margin? 0 Yes 0 No <br /> <br />b. The computed range of settlement is <br /> <br />fUo <br /> <br />ft. <br /> <br />c. Settlement of the levee crest is determined to be primarily from: <br /> <br />o Foundation consolidation <br />o Embankment compression <br />o Other (Describe): <br /> <br />d. Differential settlement offloodwalls 0 has 0 has not been accommodated in the structural design and construction. <br /> <br />Attach engineering analysis to support construction plans. <br /> <br />8.

Interior drainage has been analyzed based on joint probability of interior and exterior flooding and the capacities of pumping and outlet <br />facilities to provide the established level of flood protection. 0 Yes 0 No <br /> <br />If No, attach explanation. <br /> <br />g.
