1 SPECIAL flOOD HAZARD AREAS INUNDATED BY 100- YEAR FLOOD ZONE A No base flood elevations determined. ZON E AE ZONE AH Base flood elevations determined. ZONE AO Flood depths of 1 to 3 feet (usually areas of ponding); base flood elevations determined. Flood depths of 1 to 3 feet (usually sheet flow on. sloping terrain); average depths deter- mined. For areas of alluvial fan flooding; velocities also determined, ZONE A99 To be protected from 100-year flood by Federal flood protection system under con- struction; no base flood elevations deter- mined. ZONE V Coastal flood with velocity hazard (wave action); no base flood elevations determined. ZONE VE Coastal flood with velocity hazard (wave action); base flood elevations determined.

The community map repository should be consulted for more detailed data on BFEs, and for any information on floodway delineations, prior to use of this map for property purchase or construction purposes. Areas of Special Flood Hazard (1 OO-year flood) include Zones A, AE, A 1- A30, AH, AO, A99, V, VE and V1-V30. Certain areas not in Special Flood Hazard Areas may be protected by flood control structures. ZONE X '\ \ \ \ \ \ \ \ \ \ \ \ \ _ _---1 Boundaries of the floodways were computed at cross sections and interpolated between cross sections. The floodways were based on hydraulic considerations with regard to requirements of the Federal Emergency Management Agency. Floodwaywidths in some ,areas may be too narrow to show to scale. .Refer to Floodway Data Table where floodway width is shown at 1/20 inch. Corporate limits shown are current as of the date of this map. The user should contact appropriate community officials to determine if corporate limits have changed subsequent to the issuance of this map.

Users should be aware that BFEs shown on the FIRM represent rounded whole-foot elevations and therefore may not exactly reflect the flood elevation data presented in the FIS. For construction and/or floodplain management purposes, users are encouraged to use the flood elevation data presented in this FIS in conjunction with the data shown on the FIRM. Elevation Reference Marks (ERM) elevations listed on this map were obtained and/or developed to establish vertical control for determination of flood elevatbns and floodplain boundaries portrayed on this map. Users should be aware that these ERM elevations may have changed since the publication of this map. To obtain up-to-date-elevation information on National Geodetic Survey (NGS) ERMs shown on this map, please contact the Infonnation Services Branch of the NGS at (301) 713-3242, or visit their website at www.ngs.noaa.gov. Map users should seek verification of non-NGS ERM monument elevations when using these elevations for construction or floodplain management purposes.
