The Q3 cannot be used as the official NFIP map for site design or flood risk determinations. FEMA has also produced Q3 Flood Data, which includes certain features of the FIRM, and may be used for insurance purposes and planning activities. More recent flood map products include digital FIRMs, which are created using digital methods and can be incorporated into a community's Geographic Information System (GIS). The FHBM is an older version of a flood map and is based on approximate data. Welcome to Flood Hazard Mapping Annex The following site is accessible to Federal Emergency Management Agency (FEMA) staff, and FEMA contractors, mapping partners, mapping program stakeholders, and National Flood Insurance Program (NFIP) map users, as well as Risk MAP staff and state, tribal, and local mitigation planners. The FBFM is no longer produced current FIRMs include all of this information. The FBFM is a version of a flood map that shows only the floodway and flood boundaries. At a minimum, flood maps show flood risk zones and their boundaries, and may also show floodways and Base Flood Elevations (BFEs). The FIRM is the most common type of map and most communities have this type of map. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones.A Flood Insurance Rate Map (FIRM), Flood Boundary and Floodway Map (FBFM), and Flood Hazard Boundary Map (FHBM) are all flood maps produced by FEMA. These areas have a 26% chance of flooding over the life of a 30 year mortgage. VE - Coastal areas with a 1% or greater chance of flooding and an additional hazard associated with storm waves. Average flood depths derived from detailed analyses are shown within these zones. You can also call 95 and provide your address and zip code. You can determine if your property is located in the SFHA by using the Broward County’s interactive map viewer. These areas have a 26% chance of flooding over the life of a 30 year mortgage. This FEMA effort is referred to as map modernization and has evolved as a growing number of industries were impacted by out-of-date flood data. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones.ĪO - River or stream flood hazard areas, and areas with a 1% or greater chance of shallow flooding each year, usually in the form of sheet flow, with an average depth ranging from 1 to 3 feet. These areas have a 26% chance of flooding over the life of a 30 ‐ year mortgage. Because detailed analyses are not performed for such areas no depths or base flood elevations are shown within these zones.ĪE - The base floodplain where base flood elevations are provided.ĪH - Areas with a 1% annual chance of shallow flooding, usually in the form of a pond, with an average depth ranging from 1 to 3 feet. The SFHA designations which appear within Bay County are explained further below.Ī - Areas with a 1% annual chance of flooding and a 26% chance of flooding over the life of a 30 year mortgage. 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). 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 flood hazards shown on the FIRM are used to. ![]() 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. flood study to update Flood Insurance Rate Maps (FIRMs) for communities in coastal New Jersey and New York. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood. ![]() 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. ![]() Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA).
