About Flood Zones: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).

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the Texas Central (FIPS 4203) State Plane projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

This is a feature layer view of parcel center locations from the official Leon County Real Estate Portfolio as maintained by Leon County Real Estate Department (LCRED). This view displays only features that are coded as "Water Management". Water Management locations typically fall into the following categories:drainage, drainage-federal,flood, flood-county, flood-federal, SWMF, SWMF-federal, wetlands, wetlands-federal,non-flood

This feature layer and its content are provided publicly by FEMA (REST service). To improve performance for this resource, TLCGIS has extracted LOMA features from the FEMA service that are within Leon County's jurisdiction and published them for consumption by our user community. Automated update frequency for this extracted layer is weekly (Mondays). The popup for this layer includes links to the official FEMA PDF documents for each flood letter.The LOMA point layer indicates coordinates for Letters of Map Amendment, which can affect flood zone determination without a map change. Please be aware that LOMA point layer is provided ‘as-is’ and that there are several issues that must be considered before using this information. The first is its positional accuracy. Where the point is shown on the map may, or may not, be totally accurate as there are a variety of methods that can be used to translate a mailing address into a geographic coordinate (geocoding). The second is the completeness of the dataset. This point layer only includes LOMAs that have a coordinate associated with them. There are a number of LOMAs that have been processed by FEMA which do not have any type of a coordinate associated with them and those LOMAs are not included within this data.

The Flood Risk Review Meeting for Gadsden, Leon, Liberty, and Wakulla Counties was held on October 4, 2017. This meeting was coordinated by the NWFWMD as part of the Lower Ochlockonee Watershed Risk MAP Project.
