<br />. Brief description of the levee <br /> <br />. Description of protected area <br /> <br />. Brief description of river characteristics by the <br />levee <br /> <br />. Levee composition and adjacent area soils <br /> <br />. Cross-sectional measurements of the levee and length <br /> <br />. Description of condition of levee in 10 categories <br /> <br />. Estimated ground elevations, flood elevations, <br />freeboards, termination conditions, and a plan sketch <br /> <br />c. Stationinq and Cross-Referencinq. - The stat~oning used <br />for this study is that used in the FEMA flood insurance studies. <br />The stations are given as the distance in river miles above Lee <br />Ferry, Arizona. The convention used in this report for left and <br />right banks, is referenced based on facing downstream. A <br />schematic illustrating this, as well as the terms used on the <br />inspection sheets, is included as the first page of Appendix B. <br />The inspection sheets provide approximate stationing of the <br />inventoried levees. Their locations are on the topography maps <br />(Appendix C) by similar stationing. The water surface profiles <br />(Appendix D) are also indexed by this same stationing. The pages <br />in Appendixes B, C, and D are arranged sequentially starting at <br />the upstream end of the inventory reach. <br /> <br />7. Inventorv of Levee SYstems. <br /> <br />Following is a description of each levee segment (or site) <br />in the study area with respect to its meeting or not meeting FEMA <br />standards. The descriptions clarify information presented on the <br />inspection sheets in Appendix B (and the other appendixes). It <br />should be noted again that the inventory only identified: <br />observable surface conditions, and no information relating to the <br />engineering adequacy of levee features should be inferred. <br /> <br />It was found that all inventoried levee segments do not <br />appear to meet FEMA standards and would need to be upgraded to <br />the requirements outlined in section 6a, FEMA Interim Levee <br />POlicy, in any attempt to secure FEMA flood plain map revisions. <br />A potential levee at site G is being evaluated by the corps and <br />the City of Grand Junction. If constructed, this levee would <br />meet FEMA standards. Table 2 provides a summary of the 19 <br />inspected (and 1 proposed) sites: <br /> <br />7 <br />
