<br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE CITY <br />OF ENGLEWOOD, ARAPAHOE COUNTY, COLORADO, UNDER THE NATIONAL FLOOD <br />INSURANCE PROGRAM <br /> <br />On August 16, 1995, the Federal Emergency Management Agency identified Special Flood Hazard Areas <br />(SFHAs) in the City of Englewood, Arapahoe 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 />flcx:d having a I-percent chance of being equaled or exceeded in any given year (base :fk:lm:t 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 1 %8, as amended (Title xm <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 along Big Dry Creek of <br />major drainageway features that consist of bank protection, grade-control structures, crossing structures, <br />and detention facilities, including Pond 1 Ojust upstream of South University Boulevard, and has resulted <br />in a revised delineation of the regulatory floodway, increases and decreases in SFHA width, arx:l. increased <br />and decreased BFEs for Big Dry Creek. The table below indicates existing and modified BFEs for sel ected <br />locations along the affected lengths of the flooding source(s) cited above. <br /> <br />Location <br /> <br />Existing BFE <br />(feet) * <br /> <br />Modified BFE <br />(feet) * <br /> <br />Approximately 1,050 feet downstream <br />of South Santa Fe Drive <br />Approximately 1,000 feet upstream <br />of Lehow Avenue <br /> <br />5,307 <br />5,381 <br /> <br />5,309 <br />5,380 <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 flcx:d 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 /> <br />Any person having knowledge or wishing to comment on these changes should immediately notify: <br /> <br />The Honorable Tom Bums <br />Mayor, City of Englewood <br />3400 South Elati Street <br />Englewood, Colorado 80110 <br />
