<br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR TIlE CITY <br />OF LONGMONT, BOULDER COUNTY, COLORADO, UNDER TIlE NATIONAL FLOOD <br />INSURANCE PROGRAM <br /> <br />On June 2, 1995, the Federal Emergency Management Agency identified Special Flood Hazard Areas <br />(SFHAs) in the City of Longmont, Boulder County, Colorado, through issuance of a Flood Insurance <br />Rate Map (FIRM). The Mitigation. Directorate has detennined 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 <br />(Title XIII 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 perfonned to incorporate construction of a bridge at Pike Road and more <br />detailed topographic infonnation for Lefthand Creek from approximately 400 feet downstream to <br />approximately 1,000 feet upstream of Pike Road. This has resulted in delineation of a regulatory <br />floodway and increased and decreased BFEs for Lefthand Creek, The table below indicates existing and <br />modified BFEs for selected locations along the affected lengths ofthe flooding source(s) cited above, <br /> <br />Location <br /> <br />Existing BFE <br />(feet)* <br /> <br />Approximately 50 feet upstream of footbridge <br />At Pike Road <br />Approximately 250 feet upstream of Pike Road <br /> <br />4,972 <br />4,975 <br />4,976 <br /> <br />Modified BFE <br />(feet)* <br /> <br />4,973 <br />4,974 <br />4,974 <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 <br />which he or she can request, through the Chief Executive Officer of the community, that the Mitigation <br />Directorate reconsider the detennination. Any request for reconsideration must be based on knowledge of <br />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 detennination to modifY the BFEs may itself be <br />changed, <br /> <br />Any person having knowledge or wishing to comment on these changes should immediately notifY: <br /> <br />The Honorable Leona Stoecker <br />Mayor, City of Longmont <br />350 Kimbark Street <br />Longmont, CO 80501 <br /> <br />I <br />~ <br />
