    LEGENDSPECIAL FLOOD HAZARD AREAS SUBJECT TO INUNDATION BY THE1% ANNUAL CHANCE FLOOD

    The 1% annual chance flood (100-year flood), also known as the base flood, is the flood that has a1% chance of being equaled or exceeded in any given year. The Special Flood Hazard Area is thearea subject to flooding by the 1% annual chance flood. Areas of Special Flood Hazard include ZonesA, AE, AH, AO, AR, A99, V, and VE. The Base Flood Elevation is the water-surface elevation of the1% annual chance flood.ZONE A No Base Flood Elevations determined.ZONE AE Base Flood Elevations determined.ZONE AH Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood Elevationsdetermined.ZONE AO Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depthsdetermined. For areas of alluvial fan flooding, velocities also determined.ZONE AR Special Flood Hazard Area formerly protected from the 1% annual chance flood bya flood control system that was subsequently decertified. Zone AR indicates thatthe former flood control system is being restored to provide protection from the1% annual chance or greater flood.ZONE A99 Areas to be protected from 1% annual chance flood event by a Federal floodprotection system under construction; no Base Flood Elevations determined.ZONE V Coastal flood zone with velocity hazard (wave action); no Base Flood Elevationsdetermined.ZONE VE Coastal flood zone with velocity hazard (wave action); Base Flood Elevationsdetermined.

    FLOODWAY AREAS IN ZONE AEThe floodway is the channel of a stream plus any adjacent floodplain areas that must be kept free ofencroachment so that the 1% annual chance flood can be carried without substantial increases inflood heights.

    OTHER FLOOD AREASZONE X Areas of 0.2% annual chance flood; areas of 1% annual chance flood with averagedepths of less than 1 foot or with drainage areas less than 1 square mile; andareas protected by levees from 1% annual chance flood.

    OTHER AREASZONE X Areas determined to be outside the 0.2% annual chance floodplain.ZONE D Areas in which flood hazards are undetermined, but possible.

    EFFECTIVE DATE(S) OF REVISION(S) TO THIS PANEL

    For community map revision history prior to countywide mapping, refer to the Community MapHistory table located in the Flood Insurance Study report for this jurisdiction.To determine if flood insurance is available in this community, contact your insurance agent or callthe National Flood Insurance Program at 1-800-638-6620.

    NOTES TO USERSThis map is for use in administering the National Flood Insurance Program. It does notnecessarily identify all areas subject to flooding, particularly from local drainage sources ofsmall size. The community map repository should be consulted for possible updated oradditional flood hazard information.To obtain more detailed information in areas where Base Flood Elevations (BFEs) and/orfloodways have been determined, users are encouraged to consult the Flood Profiles andFloodway Data and/or Summary of Stillwater Elevations tables contained within the FloodInsurance Study (FIS) report that accompanies this FIRM. Users should be aware thatBFEs shown on the FIRM represent rounded whole-foot elevations. These BFEs areintended for flood insurance rating purposes only and should not be used as the solesource of flood elevation information. Accordingly, flood elevation data presented in the FISreport should be utilized in conjunction with the FIRM for purposes of construction and/orfloodplain management.Coastal Base Flood Elevations (BFEs) shown on this map apply only landward of 0.0'North American Vertical Datum of 1988 (NAVD 88). Users of this FIRM should be awarethat coastal flood elevations are also provided in the Summary of Stillwater Elevations tablein the Flood Insurance Study report for this jurisdiction. Elevations shown in the Summaryof Stillwater Elevations table should be used for construction and/or floodplain managementpurposes when they are higher than the elevations shown on this FIRM.Boundaries of the floodways were computed at cross sections and interpolated betweencross sections. The floodways were based on hydraulic considerations with regard torequirements of the National Flood Insurance Program. Floodway widths and otherpertinent floodway data are provided in the Flood Insurance Study report for thisjurisdiction.Certain areas not in Special Flood Hazard Areas may be protected by flood controlstructures. Refer to Section 2.4 "Flood Protection Measures" of the Flood InsuranceStudy report for information on flood control structures for this jurisdiction.The projection used in the preparation of this map was State Plane Mississippi East FIPSZone 2301. The horizontal datum was NAD83, GRS1980 spheroid. Differences indatum, spheroid, projection or UTM zones used in the production of FIRMs for adjacentjurisdictions may result in slight positional differences in map features across jurisdictionboundaries. These differences do not affect the accuracy of this FIRM.Flood elevations on this map are referenced to the North American Vertical Datum of 1988.These flood elevations must be compared to structure and ground elevations referenced tothe same vertical datum. For information regarding conversion between the NationalGeodetic Vertical Datum of 1929 and the North American Vertical Datum of 1988, visit theNational Geodetic Survey website at http://www.ngs.noaa.gov/ or contact the NationalGeodetic Survey at the following address:NGS Information ServicesNOAA, N/NGS12National Geodetic SurveySSMC-3, #92021315 East-West HighwaySilver Spring, Maryland 20910-3282(301) 713-3242To obtain current elevation, description, and/or location information for bench marksshown on this map, please contact the Information Services Branch of the NationalGeodetic Survey at (301) 713-3242 or visit its website at http://www.ngs.noaa.gov/.Base map information shown on this FIRM was provided in digital format by the State ofMississippi and the U.S. Census Bureau. This information was photogrammetricallycompiled at a scale of 1:400 from aerial photography dated March 2006.This map reflects more detailed and up-to-date stream channel configurations thanthose shown on the previous FIRM for this jurisdiction. The floodplains and floodways thatwere transferred from the previous FIRM may have been adjusted to conform to these newstream channel configurations. As a result, the Flood Profiles and Floodway Data tables inthe Flood Insurance Study report (which contains authoritative hydraulic data) may reflectstream channel distances that differ from what is shown on this map.Corporate limits shown on this map are based on the best data available at the time ofpublication. Because changes due to annexations or de-annexations may have occurredafter this map was published, map users should contact appropriate community officials toverify current corporate limit locations.Please refer to the separately printed Map Index for an overview map of the countyshowing the layout of map panels; community map repository addresses; and a Listing ofCommunities table containing National Flood Insurance Program dates for each communityas well as a listing of the panels on which each community is located.Contact the FEMA Map Service Center at 1-800-358-9616 for information on availableproducts associated with this FIRM. Available products may include previously issuedLetters of Map Change, a Flood Insurance Study report, and/or digital versions of this map.The FEMA Map Service Center may also be reached by Fax at 1-800-358-9620 and itswebsite at http://msc.fema.gov/.If you have questions about this map or questions concerning the National FloodInsurance Program in general, please call 1-877-FEMA MAP (1-877-336-2627) or visit theFEMA website at http://www.fema.gov/business/nfip/.
