The modified Base Flood Elevations (BFEs) <br />revise the FIRM for the community. <br /> <br />The changes are being made pursuant to Section 206 of the Flood Disaster Protection Act of 1973 (Public <br />Law 93-234) and are in accordance with the National Flood Insurance Act of 1968, as amended <br />(TitleXIII of the Housing and Urban Development Act of 1968, Public Law 90-448), 42 U.S.C, <br />4001-4128, and 44 CFR Part 65, <br /> <br />A hydraulic analysis was performed to incorporate the channel modifications associated with the Red <br />Leaf Development along West Lake Channel upstream of Lowell Boulevard and has resulted in a revised <br />delineation of the regulatory floodway, a decrease in SFHA width, and decreased BFEs for West Lake <br />ChanneL' The BFEs will be contained in the channel from approximately 200 feet upstream to <br />approximatelY.2,200 feet upstream of Lowell Boulevard, The table below indicates existing and modified <br />- ," ,Y,., . <br />BFEs for selected lOcations' along the affected lengths of the flooding source( s) cited above. <br />". ,'I. <br />'-"{ <br /> <br />Location <br /> <br />Existing BFE <br />(feet)* <br /> <br />Modified BFE <br />(feet)* <br /> <br />Approximately 125 feet upstream of Lowell Boulevard <br /> <br />5,270 <br /> <br />5,268 <br /> <br />*National Geodetic Vertical Datum, rounded to nearest whole foot <br /> <br />Under the above-mentioned Acts of 1968 and 1973, the Federal Insurance and Mitigation Administration <br />must develop criteria for floodplain management.
