CHANGES ARE MADE IN DETERMINATIONS

OF BASE FLOOD ELEVATIONS FOR THE CITY OF OKLAHOMA CITY,

OKLAHOMA COUNTY, OKLAHOMA, UNDER THE NATIONAL FLOOD INSURANCE PROGRAM

On September 2, 1988, the Federal Emergency Management Agency (FEMA) identified Special Flood Hazard Areas (SFHAs) in the City of Oklahoma City, Oklahoma County, Oklahoma, through issuance of a Flood Insurance Rate Map (FIRM).

The Mitigation Directorate has determined that modification of the elevations of the flood having a 1-percent chance of occurrence in any given year (base flood) for certain locations in the City of Oklahoma City is appropriate. The modified base (100-year) flood elevations (BFEs) revise the FEMA FIRM for the community.

The changes are being made pursuant to Section 206 of the Flood Disaster Protection Act of 1973 (Public Law 93-234), and are in accordance with the National Flood Insurance Act of 1968, as amended (Title XIII of the Housing and Urban Development Act of 1968, Public Law 90-448), 42 U.S.C. 4001-4128, and 44 CFR Part 65.

A hydraulic analysis was performed to incorporate a channelization project and more detailed topographic information and has resulted in a revised delineation of the regulatory floodway and changes in SFHAs and BFEs along Lightning Creek, from approximately 400 feet upstream of Southwest 44th Street to just upstream of Interstate 240, and along Lighting Creek Tributary 3, from its confluence with Lightning Creek to just upstream of South Walker Avenue. As a result of the aforementioned channelization project, the 100-year flood on Lightning Creek and Lightning Creek Tributary 3 is contained in the channel. The table below indicates the modified BFEs for several locations along the affected lengths of Lightning Creek and Lightning Creek Tributary 3. Existing BFE
