<br />I, <br /> <br />. <br /> <br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE CITY OF <br />AURORA AND ARAPAHOE COUNTY, COLORADO, UNDER THE NATIONAL FLOOD INSURANCE <br />PROGRAM <br /> <br />On August 16, 1995, the Federal Emergency Management Agency (FEMA) identified Special Flood <br />Hazard Areas (SFHAs) in the City of Aurora and Arapahoe County, Colorado, through issuance of a Flood <br />Insurance Rate Map (FIRM) for both communities, <br /> <br />The Mitigation Directorate has determined that modification of the elevations of the flood having a <br />I-percent chance of being equaled or exceeded in any given year (base flood) for certain locations in these two <br />communities is appropriate. The modified base flood elevations (BFEs) revise the FEMA FIRM for these <br />communities, <br /> <br />The changes are being made pursuant to Section 206 of the Flood Disaster Protection Act of 1973 <br />(Public Law 93-234) and are in accordance with the National Flood Insurance Act of 1968, as amended (Title <br />XIII 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 and to <br />correct errors in the hydraulic model used to develop the effective FIRM, and has resulted in a revised <br />delineation of the regulatory floodway and SFHA, and modified BFEs from approximately 600 feet <br />downstream of Piney Creek to approximately 800 feet upstream of East Arapahoe Road, The table below <br />indicates the modified BFEs for several locations along the affected lengths of Cherry Creek and Cherry Creek <br />Right Overbank Splitflow, <br /> <br />Location <br /> <br />Existing BFE <br />(feet)* <br /> <br />Modified BFE <br />(feet)* <br /> <br />Cherry Creek: <br />Approximately 600 feet downstream of <br />confluence of Piney Creek <br />Approximately 100 feet downstream of <br />East Arapahoe Road <br />Approximately 400 feet upstream of <br />East Arapahoe Road <br />Approximately 800 feet upstream of <br />East Arapahoe Road <br /> <br />5,620 <br /> <br />5,620 <br /> <br />5,644 <br /> <br />5,642 <br /> <br />5,646 <br /> <br />5,647 <br /> <br />5,647 <br /> <br />5,647 <br />
