<br />whatever means are available when and if the reservoir owners <br />attempt to make changes which would reduce the flood routing <br />capability. <br /> <br />Rule 8. Criteria for DetermininQ When che Effects of Levees on F100ds Mav <br />Be Taken Into Account: <br /> <br />A. OWnershiD. Privately owned, operated, or maintained levee <br />systems will not be considered in the hydraulic analysis to be <br />performed pursuant to rule 5 or rule 6 unless a local ordinance <br />mandates operation and maintenance of the levee system and the <br />criteria set forth below are met. Levees for which the <br />community, State, or Federal government has responsibility for <br />operation and maintenance will be considered provided that the <br />criteria set forth below are met. <br /> <br />B. Freeboard. A minimum levee freeboard of 3 feet shall be <br />necessary, with an additional 1 foot of freeboard within 100 <br />feet of either side of structures within the levee or wherever <br />the flow is constricted, such as at bridges. An additional 0.5 <br />foot above this minimum is also required at the upstream end, <br />tapering to the minimum at the downstream end of the levee. <br /> <br />C. Field Insoection and Maintenance. The levee shall be <br />structurally sound and adequately maintained. Certification <br />from a Federal agency, State Agency, or a registered <br />professional engineer that the levee meets the minimum <br />freeboard criteria above and that it appears, on visual <br />inspection, to be structurally sound and adequately maintained <br />shall be required. Levees that have obvious structural <br />defects, or that are obviously lacking in proper maintenance, <br />shall not be considered in the hydraulic analysis. <br /> <br />o. <br /> <br />Internal DrainaQe. Where credit will be given <br />providing 100-year protection, the adequacy of <br />drainage systems shall be evaluated. Areas subject <br />from inadequate interior drainage behind levees will <br />using standard procedures. <br /> <br />to levees <br />interior <br />to flooding <br />be mapped <br /> <br />E. Human Intervention and ODeration. In general, evaluation of <br />levees shall not consider human intervention (e.g., capping of <br />levees by sandbagging, earthfill, or flashboards) for the <br />purpose of increasing a levee's design level of protection <br />during an imminent flood. Human intervention shall only be <br /> <br />-20- <br />
