| NSFHA |
(No Special Flood Hazard Area) Although it may not be subject to the
100-year flood, floods of greater magnitude could occur there. In addition, certain
structures may be damaged by the local drain. |
| Zone D |
Areas of undetermined, but possible, flood hazards. Area in which
flood hazards are undetermined. Unstudied area in which flood hazards are undetermined but
flooding is possible. |
| Zone C |
Areas of minimal flooding determined to be outside the 500-year
flood plain. This area has been identified as an area of moderate or minimal flood hazard
from the principal source of flood in the area. |
| Zone B |
Areas between the limits of the 100-year flood and 500-year flood;
or certain areas subject to 100-year flooding with average depths less than one foot or
where the contributing drainage area is less than one square mile; or areas protected by
levees from the base flood. This area has been identified in the community flood insurance
study as an area of moderate to minimal hazard from the principal source of flood in the
area. |
| Zone X |
(Unshaded) Areas determined to be outside of the 100-year flood
plain. This area has been identified in the community flood insurance study as an area of
moderate or minimal hazard from the principal source of flood in the area. |
| Zone X |
(Shaded) Areas of the 500-year flood; areas of the 100-year flood
with average depths of less than one foot within drainage area less than one square mile;
or areas protected by levees from 100-year flood. This area has been identified in the
community flood insurance study as an area of moderate or minimal hazard from the
principal source of flood in the area. |

| . |
|
| Zone A
|
Area of 100-year flood; base flood elevation and flood hazard
factors are not determined. |
| Zone
AE |
Area
of 100-year flood; A SFHA subject to inundation by the 100-year flood determined in a
flood insurance study by detailed methods. Base flood elevations are shown within this
zone. |
| Zone AH |
Area of 100-year shallow flooding where depths are between 1-3 feet;
base flood elevations are shown, but no flood hazards have been determined. Base flood
elevations derived from detailed hydraulic analysis are shown in this zone. |
| Zone
AO |
Area
of 100-year shallow flooding where depths are between 1-3 feet; average depths of
inundation are shown, but no flood hazard factors have been determined. For areas of
alluvial fan flooding, velocities have been determined. Average flood depths derived from
detailed hydraulic analysis are shown within this zone. |
| Zone A1-A30 |
Areas of 100-year flood; base flood elevations and flood hazard
factors determined. Base flood elevations are shown within these zones. |
| Zone
A99 |
Areas
of 100-year flood to be protected by flood protection system under construction; base
flood elevations and flood hazard factors have not been determined. |
| Zone AR |
Area of special flood hazard which results from the decertification
of a previously accredited flood protection system which is determined to be in the
process of being restored to provide a 100-year of greater level of flood protection. |
| Zone V |
Areas of 100-year coastal flood with velocity hazard (wave action);
the base flood elevations and hazard factors not determined. |
| Zone VE |
Areas of 100-year coastal flood with velocity hazard (wave action);
the base flood elevations have been determined. |
| Zone V1-V30 |
Areas of 100-year coastal flood with velocity hazard (wave action);
base flood elevations and flood hazard factors have been determined. |

Program Types______________ |

| . |
|
| Emergency |
Typically
the first phase of a community's participation in the NFIP. Insurance is provided at
subsided rates on insurable structures in the community before the effective date of the
initial Flood Insurance Rate Maps. |
| Regular |
The phase of a community's
participation in the NFIP during which more comprehensive flood-plain management
requirements are imposed. Higher amounts of insurance are available, depending on Special
Flood Hazard Areas and elevations determined in the Flood Insurance Study. |
| Not In Program |
The
community is not participating in the NFIP either by community choice or by NFIP decision.
Flood insurance is not available in non-participating communities, |
| Sanctioned |
The community has been
identified as having Special Flood Hazard Areas but is not participating in the NFIP as
the result of suspension, withdrawal, or failure to join the program after an initial
emergency phase. Flood insurance is not available in sanctioned communities. |
| Suspended |
The
community has been suspended from the NFIP. Usually communities are suspended for not
enacting or enforcing proper NFIP floodplain management regulations. Flood insurance is
not available in suspended communities. |
