<br />E. LEVEE/FLOODWALL <br /> <br />1. Svstem Elements <br /> <br />a. This Levee/Floodwall analysis is based on (check one): <br /> <br />D upgrading of an existing leveelfloodwall system <br />D a newly constructed levee/floodwall system <br />D reanalysis of an existing levee/f1oodwall system <br /> <br />b. Levee elements and locations are (check one): <br /> <br />D earthen embankment, dike, berm, etc. <br />D structural f100dwall <br />D Other (describe): <br /> <br />Station <br />Station <br />Station <br /> <br />to <br />to <br />to <br /> <br />c. Structural Type (check one): <br /> <br />D monolithic cast-in place reinforced concrete <br />D reinforced concrete masonry block <br />D sheet piling <br />D Other (describe): <br /> <br />d. Has this levee/f1oodwall system been certified by a Federal agency to provide protection from the base flood? <br /> <br />DYes D No <br /> <br />If Yes, by which agency? <br /> <br />e.
