<br />.. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />4 <br /> <br />. Please provide backup data and calculations that support the discharge of 2,217 cubic feet per <br />second (cfs) used at Cross Sections 2140 and 2050 in the downstream proposed conditions model. <br /> <br />. The proposed conditions model uses the effective discharge 00,040 cfs at the downstream end of <br />the RCa at the proposed Gun Club Road. However, based on the submitted data, it appears that the <br />proposed project will cause the discharge downstream of the proposed Gun Club Road to be lower <br />than the effective discharge. Please provide a hydrologic analysis to determine the appropriate <br />discharge, or provide an explanation for using the effective discharge. <br /> <br />. Please provide a topographic work map that reflects as-built conditions for the revised reach. The <br />work map should include the revised floodplain boundary delineations, locations and orientations <br />of all cross sections used in the HEC-RAS hydraulic computer model, and certification by a <br />registered professional engineer or land surveyor. The final post-project conditions model must <br />correspond to the as-built plans at alllocations and show a logical transition between the revised and <br />existing conditions floodplain boundary delineations. In addition, please submit Form 5, entitled <br />"Riverine/Coastal Mapping Form." <br /> <br />. Please submit a diskette containing the input and output files for all submitted hydraulic models. <br />Please also submit Form 4, entitled "Riverine Hydraulic Analysis Form." <br /> <br />. Please provide an annotated FIRM to show the revised floodplain boundary delineations. <br /> <br />After receiving appropriate documentation to show that the project has been completed, FEMA will initiate <br />a revision to the FIRM. <br /> <br />The basis of this CLOMR is, in whole or in part, a culvert project. NFIP regulations, as cited in <br />Paragraph 60.3(b )(7), require that communities assure that the flood-canying capacity within the altered or <br />relocated portion of any watercourse is maintained. This provision is incorporated into your community's <br />existing floodplain management regulations. Consequently, the ultimate responsibility for maintenance of <br />the culverts rests with your community. <br /> <br />This CLOMR is based on minimum floodplain management criteria established under the NFIP. Your <br />community is responsible for approving all floodplain development and for ensuring all necessary permits <br />required by Federal or State law have been received. State, county, and community officials, based on <br />knowledge of local conditions and in the interest of safety, may set higher standards for construction in the <br />SFHA. If the State, county, or community has adopted more restrictive or comprehensive floodplain <br />management criteria, these criteria take precedence over the minimum NFIP criteria. <br /> <br />If you have any questions regarding floodplain management regulations for your community or the NFIP <br />in general, please contact the Consultation Coordination Officer (CeO) for your community.
