This study has developed flood risk data for various areas of the community that will be used to establish actuarial flood insurance rates and to assist the community in its efforts to promote sound floodplain management. Minimum floodplain management requirements for participation in the National Flood Insurance Program (NFIP) are set forth in the Code of Federal Regulations at 44 CFR, 60.3. In some States or communities, floodplain management criteria or regulations may exist that are more restrictive or comprehensive than the minimum Federal requirements. In such cases, the more restrictive criteria take precedence, and the State (or other jurisdictional agency) will be able to explain them. 1.2 Authority and Acknowledgments The sources of authority for this FIS report are the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973. This FIS was prepared to include all jurisdictions within Lee County into a countywide format FIS. Information on the authority and acknowledgments for each jurisdiction with a previously printed FIS report included in this countywide FIS is shown below. Lee County (Unincorporated Areas): The hydrologic and hydraulic analyses for the May 15, 1991, FIS report were performed by Post, Buckley, Schuh and Jernigan, Inc. for the Federal Emergency Management Agency (FEMA), under Contract No. EMW-86-C- 0113, That study was completed in September 1987 (Reference 1). For this countywide FIS, the hydrologic and hydraulic analyses were performed by URS Corporation, for the Georgia Department of Natural Resources (DNR), under Contract No. 761-80189. This work was completed in August 2008. Base map information shown on the FIRM was derived from aerial photography 1 produced for Lee County, Georgia, dated 2007 at a scale of 1:20,000. Users of this FIRM should be aware that minor adjustments may have been made to specific base map features. 1.3 Coordination An initial Consultation Coordination Officer’s (CCO) meeting is held typically with representatives of Georgia DNR, the communities, and the study contractor to explain the nature and purpose of a FIS, and to identify the streams to be studied by detailed methods. A final CCO meeting is held typically with the same representatives to review the results of the study. Pre-Countywide Analysis For the May 15, 1991 FIS, an initial CCO meeting was held on January 22, 1986, and attended by representatives of FEMA, Lee County, and the study contractor to explain the nature and purpose of a FIS, and to identity the streams to be studied. The results of the study were reviewed at the final CCO meeting held on June 20, 1990, and attended by representatives FEMA, study contractor, and the community. This Countywide Analysis For this countywide FIS an initial CCO meeting was held on January 28, 2007, and attended by representatives of the Georgia DNR, Southwest Georgia Regional Development Center, Lee County, and the mapping contractor. The results of the study were reviewed at the final CCO meeting held on November 5, 2008, and attended by representatives of Lee County and the City of Leesburg. All problems raised at that meeting have been addressed in this study. 2.0 AREA STUDIED 2.1 Scope of Study This FIS report covers the geographic area of Lee County, Georgia, including the incorporated communities listed in Section 1.1. Approximate analyses were used to study those areas having a low development potential or minimal flood hazards. The scope and methods of study were proposed to, and agreed upon, by FEMA, the Georgia DNR, and the study contractor. Floodplain boundaries have been delineated based on more up-to-date topographic data. 2 2.2 Community Description Lee County is in southwest Georgia and is bordered on the north by Sumter County; on the west by Terrell; on the south by Dougherty County; and on the east by Worth and Crisp Counties.
