<br />. <br /> <br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE CITY OF <br />AURORA AND THE UNINCORPORATED AREAS OF ADAMS COUNTY, COLORADO, UNDER THE <br />NATIONAL FLOOD INSURANCE PROGRAM <br />On September 30, 1992, the Federal Emergency Management Agency (FEMA) <br />identified Special Flood Hazard Areas (SFHAs) in the City of Aurora and the <br />unincorporated areas of Adams County, Colorado, through issuance of a Flood <br />Insurance Rate Map (FIRM). <br /> <br /> <br />The Mitigation Directorate has determined that modification of the <br /> <br /> <br />elevations of the flood having a l-percent chance of occurrence in any given <br /> <br /> <br />year (base flood) for certain locations in the City of Aurora is appropriate. <br /> <br /> <br />The modified base (lOO-year) flood elevations (BFEs) revise the FEMA FIRM for <br /> <br /> <br />the community. <br /> <br /> <br />The changes are being made pursuant to Section 206 of the Flood Disaster <br />Protection Act of 1973 (P.L. 93-234), and are in accordance with the National <br />Flood Insurance Act of 1968, as amended (Title XIII of the Housing and Urban <br />Development Act of 1968, P.L. 90-448), 42 U.S.C. 4001-4128, and 44 CFR <br />Part 65. <br /> <br />A hydraulic analysis was performed to incorporate the construction of <br /> <br /> <br />reinforced concrete box culverts under Sable Boulevard along Sable Ditch and <br /> <br /> <br />has resulted in a revised delineation of the regulatory floodway, a reduction <br /> <br /> <br />in SFHA, and modified BFEs from approximately 500 feet downstream of Sable <br /> <br /> <br />Boulevard to approximately 400 feet upstream of Sable Boulevard. The table <br /> <br /> <br />below indicates the modified BFEs for several locations along the affected <br /> <br /> <br />length of Sable Ditch. <br />
