<br />. <br /> <br />, <br /> <br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE CITY <br />OF LOUISVILLE, BOULDER COUNTY, COLORADO, UNDER THE NATIONAL FLOOD <br />INSURANCE PROGRAM <br /> <br />On May 6, 1996, the Federal Emergency Management Agency identified Special Flood Hazard <br />Areas (SFHAs) in the City of Louisville, Boulder County, Colorado, through issuance of a Flood Insurance <br />Rate Map (FIRM). The Mitigation Directorate has determined that modification of the elevations of the <br />flood having a I-percent chance of being equaled or exceeded in any given year (base flood) for certain <br />locations in this community is appropriate, The modified base flood elevations (BFEs) revise the FIRM <br />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 (Title XIII <br />of the Housing and Urban Development Act of 1968, Public Law 90-448), 42 U,S,C. 4001-4128, and <br />44 CFR Part 65. <br /> <br />A hydraulic analysis was performed to incorporate the effects of construction of a detention basin at Middle <br />School Park and installation of approximately 2,600 linear feet of 5-foot-diameter reinforced-concrete pipe <br />culvert from Middle School Park to an outfall point on the east side of State Highway 42, just south of <br />where Short Street terminates. This has resulted in increases and decreases in SFHA width, removal of <br />the SFHA from the Burlington Northern Railway to Jefferson Avenue, and increased and decreased BFEs <br />and removal of some BPEs for the flooding source known as Drainageway A, The table below indicates <br />existing and modified BPEs for selected locations along the affected lengths of the flooding source(s) cited <br />above, <br /> <br />Location <br /> <br />Existing BFE <br />(feet)* <br /> <br />Modified BFE <br />(feet)* <br /> <br />At Main Street <br />At Middle Park School Detention Pond <br />Area near intersection of <br />Front Street and Pine Street <br /> <br />5,350 <br />5,371 <br /> <br />None <br />5,373 <br /> <br />5,332 <br /> <br />5,330 <br /> <br />"National Geodetic Vertical Datum, rounded to nearest whole foot <br /> <br />Under the above-mentioned Acts of 1968 and 1973, the Mitigation Directorate must develop criteria for <br />floodplain management. To participate in the National Flood Insurance Program (NFIP), the community <br />must use the modified BFEs to administer the floodplain management measures of the NFIP, These <br />modified BFEs will also be used to calculate the appropriate flood insurance premium rates for new <br />buildings and their contents and for the second layer of insurance on existing buildings and contents, <br /> <br />Upon the second publication of notice of these changes in this newspaper, any person has 90 days in which <br />he or she can request, through the Chief Executive Officer of the community, that the Mitigation <br />Directorate reconsider the determination, Any request for reconsideration must be based on knowledge <br />of changed conditions or new scientific or technical data, All interested parties are on notice that until the <br />90-day period elapses, the Mitigation Directorate's determination to modify the BFEs may itself be <br />changed, <br />
