FEMA Flood Ways and FEMA Flood Zones (FEMA Maps Online)

FEMA Flood Ways, FEMA Flood Zones, and FEMA FIRM (Flood Insurance Rate Maps) panels are available in Surety^® and Surety^® Pro Customized Online Mapping. This information is valuable to determine whether or not a subject is in a Flood Zone which can affect the value and management of the land.

To enable the FEMA Flood Zones or FIRM Panels Layer click on layers button in the right hand panel.

Click on the "+" Button next to Other and then the "+" button next to FEMA Layers to expand them.

Select the box next to FEMA Flood Zones

If zoomed in far enough, the map will become overlay with different colors and labels depending on flood zone or flood way that exists.

Here is a description of the different zone classifications. (Information retrieved from Fema.gov)

	The 100-year or base floodplain. There are six types of A Zones:
Zone A	A	The base floodplain mapped by approximate methods, i.e., BFEs are not determined. This is often called an unnumbered A Zone or an approximate A Zone.
	A1-30	These are known as numbered A Zones (e.g., A7 or A14). This is the base floodplain where the FIRM shows a BFE (old format).
	AE	The base floodplain where base flood elevations are provided. AE Zones are now used on new format FIRMs instead of A1-A30 Zones.
	AO	The base floodplain with sheet flow, ponding, or shallow flooding. Base flood depths (feet above ground) are provided.
	AH	Shallow flooding base floodplain. BFEs are provided.
	A99	Area to be protected from base flood by levees or Federal Flood Protection Systems under construction. BFEs are not determined.
	AR	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.
Zone V and VE	V	The coastal area subject to a velocity hazard (wave action) where BFEs are not determined on the FIRM.
Zone V and VE	VE	The coastal area subject to a velocity hazard (wave action) where BFEs are provided on the FIRM.
Zone B and Zone X (shaded)		Area of moderate flood hazard, usually the area between the limits of the 100-year and 500-year floods. 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.
Zone C and Zone X (Unshaded)		Area of minimal flood hazard, usually depicted on FIRMs as above the 500- year flood level. Zone C may have ponding and local drainage problems that don’t warrant a detailed study or designation as base floodplain. Zone X is the area determined to be outside the 500-year flood and protected by levee from 100-year flood.
Zone D		Area of undetermined but possible flood hazards.
