This is a formal determination by FEMA of a property's location and/or elevation relative to the Special Flood Hazard Area. If you think the flood map boundaries are incorrect, you can apply for a Letter of Map Change. In these areas, the risk of being flooded is reduced, but not. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones Moderate- to low-risk flood areas are designated with the letters B, C, and X on FEMA flood maps. These areas have a 26% chance of flooding over the life of a 30‐year mortgage. Until the data becomes effective, when it will appear in FEMA's National Flood Hazard Layer (NFHL), the data should not be used to rate flood insurance. Pending data are for early awareness of upcoming changes to regulatory flood map information. Zone VE - coastal areas with a 1% or greater chance of flooding and an additional hazard associated with storm waves. From the Flood Map Changes Viewer, you may view, download, and print flood maps for your location.No base flood elevations are shown within these zones. Zone V - coastal areas with a 1% or greater chance of flooding and an additional hazard associated with storm waves.Zone AE - 100-year floodplain, the base floodplain where base flood elevations are provided. The floodplains shown on this mapping tool are those delineated on the Federal Emergency Management Agencys (FEMA) effective Flood Insurance Rate Map (FIRM or.

Because detailed analyses are not performed for such areas, no base flood elevations are shown. Zone A - 100-year floodplain, areas with a 1% annual chance of flooding and a 26% chance of flooding over the life of a 30‐year mortgage. The FEMA Flood Map Service Center (MSC) is the official online public source for flood hazard information produced in support of the National Flood Insurance.High Risk Areas (Special Flood Hazard Area) Includes areas of moderate flood hazard, such as base floodplains and shallow flooding areas, and minimal flood hazard, which may still have ponding and local drainage problems. Zone X - Floodplain area with a 0.2% (or 1 in 500 chance) or less annual chance of flooding.To view the effective flood zone for a property or area, visit Hillsborough County’s Effective Flood Zone Viewer. Talk to your insurance provider about your policy and consider if you need additional coverage. Most homeowners insurances do not cover flood damage. Zone X is the area determined to be outside the 500-year flood and protected by levee from the 100-year flood.Īrea of undetermined but possible flood hazards.Flood maps, also known as Flood Insurance Rate Maps, provided by the Federal Emergency Management Agency (FEMA) are a useful tool for assessing a property’s flood risk, and also are a factor in flood insurance and building requirements. Zone C may have ponding and local drainage problems that don't warrant a detailed study or designation as base floodplain. B Zones are also used to designate base floodplains of lesser hazards, such as areas protected by levees from the 100-year flood, or shallow-flooding areas with average depths of less than one foot or drainage areas less than 1 square mile.Īrea of minimal flood hazard, usually depicted on FIRMs as above the 500-year flood level. The coastal area subject to a velocity hazard (wave action) where BFEs are provided on the FIRM map.Īrea of moderate flood hazard, usually the area between the limits of the 100-year and 500-year floods. The coastal area subject to a velocity hazard (wave action) where BFEs are not determined on the FIRM map. The base floodplain that results from the decertification of a previously accredited flood protection system that is in the process of being restored to provide a 100-year or greater level of flood protection. BFEs are provided.Īrea to be protected from base flood by levees or Federal Flood Protection Systems under construction. Base flood depths (feet above ground) are provided. The base floodplain with sheet flow, ponding or shallow flooding. On newer FIRMs, AE Zones are the same as A1-A30 Zones (i.e., BFEs are shown). BFEs are shown on a FEMA map that includes any of these zones. Known as numbered A Zones (e.g., A7 or A14). This is often called an unnumbered A Zone or an approximate A zone. The new flood map, officially known as a Flood Insurance Rate Map (FIRM), identifies areas of flood risk (high, moderate, low). Six types of 'A' zones are described below.īase flood elevations (BFE) are not determined. Please see the table below for explanations of these zones. Whatever the area shown on a FEMA FIRM map, it may include several types of floodplain zones, each designated by a letter or a combination of a letter and number(s).
