FEMA - Distance to Water Body

The distance from the location to the closest FEMA-defined water body, which includes oceans, very large lakes, and very large rivers.

Distances are calculated in actual miles up to five miles. The Data Not Available value includes distances greater than five miles.

To flag certain distance conditions, enter low and high distance ranges; be sure to specify units (feet/miles).

FEMA - Distance to 100-Year Flood Plain

The distance from the location's boundary to the flood plain.

Distances are calculated in actual miles up to five miles. The Data Not Available value includes distances greater than five miles. The boundary of a 100-year flood plain has a 1% chance of being equaled or exceeded in any given year.

To flag certain distance conditions, enter low and high distance ranges; be sure to specify units (feet/miles).

FEMA - Distance to 500-Year Flood Plain

The distance from the location's boundary to the flood plain.

Distances are calculated in actual miles up to five miles. The Data Not Available value includes distances greater than five miles. The boundary of the 500-year flood plain has a 0.2% chance of being equaled or exceeded in any given year.

To flag certain distance conditions, enter low and high distance ranges; be sure to specify units (feet/miles).

FEMA - Flood Source

The source or sources of the flood data:

• Q3FIRM Flood Data is a digital representation of certain features of FEMA's Flood Insurance Rate Map (FIRM) data. The data does not contain several features from the original FIRM data, including base flood elevations and some flood zone types. Therefore, Q3FIRM Flood Data does not replace existing hardcopy FIRM or Digital FIRM (DFIRM); AIR recommends that you use this data only as a general guide to a particular location's proximity to Special Flood Hazard Areas.

• DFIRM is a digital version of the FEMA flood insurance rate map that is designed for use with digital mapping and analysis software.

To flag flood sources, select one or more items in the selection list.

FEMA - Flood Zone Category

FEMA flood zone categories that apply to the location:

• None: Areas where there is no flood hazard

• 100-Year: Areas where there is a 1% chance of being flooded (within a 100-year flood zone)

• 500-Year: Areas where there is a 0.2% chance of being flooded (within a 500-year flood zone)

• Outside: Areas outside of a water body, or outside of 100- and 500-year flood plains

• Water Body: Includes large lakes and rivers, very close to water

• No Data: Areas where there is no flood data available

• Unknown: Areas of undetermined but possible flood hazards that apply to the location.

To flag one or more FEMA flood zone categories, select one or more items in the selection list.

FEMA Flood Zone

Indicates which FEMA flood zone the location is in.

To flag one or more flood zones, select one or more items in the selection list.

FEMA - Base Flood Elevation (BFE)

The elevation of surface water resulting from a flood that has a 1% chance of equaling or exceeding that level in any given year.

BFE values are shown in FIRM zones AE, AH, A1-A30, AR, AR/A, AR/AE, AR/A1-A30, AR/AH, AR/AO, V1-V30, and VE. BFEs are shown on Flood Insurance Rate Maps (FIRMs) and in flood profiles.

To flag base flood elevation categories, select one or more items in the selection list.

AIR - Distance to 100 year Flood Plain

The distance, in miles or feet, from the location's boundary to the 100 year flood plain.

Distances are calculated in actual miles up to five miles. The Data Not Available value includes distances greater than five miles. The 100-year flood plain is an area where the flood's boundary has at least a 1% chance of being equaled or exceeded in any given year.

To flag certain distance conditions, enter low and high distance ranges; be sure to specify units (feet/miles).

AIR - Distance to 500 year Flood Plain

The distance, in miles or feet, from the location's boundary to the 500 year flood plain.

Distances are calculated in actual miles up to five miles. The Data Not Available value includes distances greater than five miles. The 500-year flood plain is an area where the flood's boundary has at least a 0.2% chance of being equaled or exceeded in any given year.

To flag certain distance conditions, enter low and high distance ranges; be sure to specify units (feet/miles).

AIR - Flood Zone Category

Indicates location of the AIR flood zone.

• 100-Year: Areas where there is a 1% chance of being flooded, within a 100-year flood zone

• 250-Year: Areas where this is a 0.4% chance of being flooded, within a 250-year flood zone

• 500-Year: Areas where there is a 0.2% chance of being flooded, within a 500-year flood zone

• No Data: Areas where there is no flood data available

The purpose of this field is to quickly indicate whether a location is in the AIR 100-, 250-, or 500-year, or 'no data', flood zones.

To flag one or more AIR flood zone categories, select one or more items in the selection list.

Elevation

The elevation of the location, as measured from mean sea level.

During a storm surge, lower-lying properties suffer more damage than properties with higher elevations.

To flag one or more elevations, select one or more items in the selection list.
