Description: Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood. SFHAs are labeled as Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30. Moderate flood hazard areas, labeled Zone B or Zone X (shaded) are also shown on the FIRM, and are the areas between the limits of the base flood and the 0.2-percent-annual-chance (or 500-year) flood. The areas of minimal flood hazard, which are the areas outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance flood, are labeled Zone C or Zone X (unshaded). Not all of the zones mentioned above are present in Travis County.The original dataset (S_FLD_HAZ_AR) was obtained from FEMA in Oct., 2019 and can be found here: \\isilonc1\dept\tnr\skunk\GIS\Data\FLOOD AND FLOODPLAIN\A_Originals_From FEMA\48453C_20200122\48453C_20200122\TX\DFIRM_DB\ArcShape. This was then reporjected to NAD 83 State Plane Texas Central FIPS 4203 Feet by TNR GIS and stored here: \\isilonc1\dept\tnr\skunk\GIS\Data\FLOOD AND FLOODPLAIN\A_Originals_From FEMA\48453C_20200122\ReProjected_to_State_Plane. The most current floodplain & flood hazard zone related data are stored here: \\isilonc1\dept\tnr\skunk\GIS\Data\FLOOD AND FLOODPLAIN\Floodplain_dataset.gdb\Current_Data. Metadata for the original Flood Insurance Rate Map Database can be found here: \\isilonc1\dept\tnr\skunk\GIS\Data\FLOOD AND FLOODPLAIN\A_Originals_From FEMA\48453C_20200122\48453C_20200122\TX\Document\48453_20220122_metadata.xml
