<br />, <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />2 <br /> <br />Our comparison of the proposed conditions model to the existing conditions model revealed that the BFEs <br />will increase in some areas and decrease in other areas as a result of the proposed bridge waterway <br />improvements, channelization, and low-flow crossing structure. The maximum decrease in BFE, 1.0 foot, <br />will occur just downstream ofI-25. The maximum increase in BFE, 0.1 foot, will occur approximately <br />200 feet downstream ofI-25. <br /> <br />Our comparison of the proposed conditions model to the effective model revealed that the BFEs will <br />decrease as a result of the proposed bridge waterway improvements, channelization, and low-flow crossing <br />structure and more detailed topographic information. The maximum decrease in BFE, 2.0 feet, will occur <br />just downstream ofI-25. <br /> <br />Our comparison of the proposed conditions model to the effective model revealed that the width of the <br />Special Flood Hazard Area (SFHA), the area that will be inundated by the base flood, will decrease and the <br />width of the regulatory floodway will not change as a result of the proposed bridge waterway improvements, <br />channelization, and low-flow crossing structure and more detailed topographic information. <br /> <br />Upon completion of the project, your community may submit the data listed below and request that we make <br />a final determination on revising the effective FIRM and FIS report. <br /> <br />. Effective March I, 1999, FEMA revised the fee schedule for reviewing and processing requests for <br />conditional and final modifications to published flood information and maps. In accordance with <br />this schedule, the current fee for this map revision request is $3,400 and must be received before we <br />can begin processing the request. Please note, however, that the fee schedule is subject to change, <br />and you are required to submit the fee in effect at the time of the submittal. Payment of this fee shall <br />be made in the form of a check or money order, made payable in U.S. funds to the National Flood <br />Insurance Program, or by credit card. The payment must be forwarded to the following address: <br /> <br />Federal Emergency Management Agency <br />Fee-Collection System Administrator <br />P.O. Box3l73 <br />Merrifield, VA 22116-3173 <br /> <br />. As-built plans, certified by a registered professional engineer, of all proposed project elements <br /> <br />. Community acknowledgment of the map revision request <br /> <br />. Certification that all fill placed in the currently effective base floodplain and below the <br />proposed BFE is compacted to 95 percent of the maximum density obtainable with the Standard <br />Proctor Test method issued by the American Society for Testing and Materials (ASTM Standard <br />D-698) or an acceptable equivalent method for all areas to be removed from the base floodplain <br /> <br />. A copy of the public notice distributed by your community stating its intent to revise the regulatory <br />floodway, or a statement by your community that it has notified all affected property owners and <br />affected adjacent jurisdictions <br /> <br />. A letter stating that your community will adopt and enforce the modified regulatory floodway <br />
