Description: FEMA Flood data.  Data was downloaded 11/20/2019 from FEMA FIRMette.  
Cross-SectionsNormally, any FIRM that has associated flood profiles has cross sections. The S_XS table contains information about cross section lines. These lines usually represent the locations of channel surveys performed for input into the hydraulic model used to calculate flood elevations. Sometimes cross sections are interpolated between surveyed cross sections using high accuracy elevation data. Depending on the zone designation (Zone AE, Zone A, etc.), these locations may be shown on Flood Profiles in the FIS report and can be used to cross reference the Flood Profiles to the planimetric depiction of the flood hazards. This information is used in the Floodway Data Tables in the FIS report, as well as on the FIRM panels.
Base Flood ElevationsBase Flood Elevations for the 1% annual chance flood.
Flood Hazard BoundaryThe S_Fld_Haz_Ln table contains information about the flood zone boundary features for the flood risk project area. Three types of flood hazard lines exist. These are: SFHA / FLOOD ZONE BOUNDARY, LIMIT LINES, and OTHER BOUNDARY. All lines that are associated with flood hazard zone boundaries are coded in the LN_TYP field as SFHA / FLOOD ZONE BOUNDARY, with the exception of LIMIT LINES. OTHER BOUNDARY line types include lines that indicate different source citations, apparent limits, or the end of spatial extents. OTHER BOUNDARY lines are not shown on the FIRM.
Flood Hazard AreaThe S_Fld_Haz_Ar table contains information about the flood hazards within the flood risk project area. These zones are used by FEMA to designate the SFHA and for insurance rating purposes. These data are the regulatory flood zones designated by FEMA
