Are the planned/installed works in full compliance with Part 65.10 of the NFIP Regulations? <br /> <br />DYes D No <br /> <br />b. Does the operation plan incorporate all the provisions for closure devices as required in Paragraph 65.10(c)(1) of the NFIP regulations? <br />DYes D No <br /> <br />c. Does the operation plan incorporate all the provisions for interior drainage as fequired in Paragraph 65.10(c)(2) of the NFIP regulations? <br />DYes D No <br /> <br />If the answer is No to any of the above, please attach supporting documentation. <br /> <br />11. Maintenance Plan <br /> <br />a. Are the planned/installed works in full compliance with Part 65.10 of the NFIP Regulations? <br />If No, please attach supporting documentation. <br /> <br />DYes D No <br /> <br />12. Operations and Maintenance Plan <br /> <br />Please attach a copy of the formal Operations and Maintenance Plan for the levee/floodwall. <br /> <br />F. SEDIMENT TRANSPORT <br /> <br />Flooding Source: <br /> <br />Name of Structure: <br /> <br />If there is any indication from historical records that sediment transport (including scour and deposition) can affect the <br />Base Flood Elevation (BFE); and/or based on the stream morphology, vegetative cover, development of the watershed and bank conditions, there is <br />a potential for debris and sediment transport (including scour and deposition) to affect the BFEs, then provide the following information along with <br />the supporting documentation: <br /> <br />Sediment load associated with the base flood discharge: Volume <br /> <br />acre-feet <br /> <br />Debris load associated with the base flood discharge: Volume <br /> <br />acre-feet <br /> <br />Sediment transport rate <br /> <br />(percent concentration by volume) <br /> <br />Method used to estimate sediment transport: <br /> <br />Most sediment transport formulas are intended for a range of hydraulic conditions and sediment sizes; attach a detailed explanation for using the <br />selected method. <br /> <br />Method used to estimate scour and/or deposition: <br /> <br />Method used to revise hydraulic or hydrologic analysis (model) to account for sediment transport: <br />Please note that bulked flows are used to evaluate the performance of a structure during the base flood; however, FEMA does not map BFEs based <br />on bulked flows. <br /> <br />If a sediment analysis has not been performed, an explanation as to why sediment transport (including scour and deposition) will not affect the BFEs <br />or structures must be provided. <br /> <br />FEMA Form 81'89B, SEP 02 <br /> <br />Riverine Structures Form <br /> <br />MT,2 Form 3 Page 10 of 10 <br />
