<br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE <br />UNINCORPORATED AREAS OF DOUGLAS COUNTY, COLORADO, UNDER THE NATIONAL <br />FLOOD INSURANCE PROGRAM <br /> <br />On January 5, 1996, the Federal Emergency Management Agency identified Special Flood Hazard <br />Areas (SFHAs) in the unincorporated areas of Douglas County, Colorado, through issuance of a Flood <br />Insurance Rate Map (FIRM). The Mitigation Directorate has determined that modification of the elevations <br />of the flood having a I-percent chance of being equaled or exceeded in any given year (base flood) for <br />certain locations in this community is appropriate. The modified base flood elevations (BPEs) revise the <br />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 (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 more detailed topographic information, grading along <br />the west bank of Cherry Creek at the Southcreek Development, and channelization of Happy Canyon Creek <br />from the confluence with Cherry Creek to just downstream of Jordan Road and has resulted in a revised <br />delineation of the regulatory floodway, increases and decreases in SFHA width, and increased BFEs for <br />Cherry Creek. The increases in the BFEs were a result of the incorporation of more detailed topographic <br />information. The table below indicates existing and modified BFEs for selected locations along the affected <br />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 4,600 feet downstream of <br />Cottonwood Drive <br />Approximately 4,100 feet downstream of <br />Cottonwood Drive <br /> <br />5,709 <br /> <br />5,710 <br /> <br />5,711 <br /> <br />5,712 <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 /> <br />Any person having knowledge or wishing to comment on these changes should immediately notify: <br /> <br />The Honorable James Sullivan <br />Chairperson, Douglas County <br />Board of Commissioners <br />10 1 Third Street <br />Castle Rock, Colorado 80104 <br />
