ZONE CLASSIFICATIONS
PLEASE PRINT A COPY FOR FUTURE REFERENCE
Zone C, Zone X - Areas
determined to be outside 500-year floodplain determined to be outside the
1% and 0.2% annual chance floodplains.
Zone B, Zone X500 - Areas of 500-year flood; areas
of 100-year flood with average depths of less than 1
foot or with drainage areas less than 1 square mile; and areas protected
by levees
from 100-year flood. An area inundated by 0.2% annual chance flooding.
Zone A -
An area inundated by 1% annual chance flooding, for which no BFEs have
been
determined.
Zone AE -
An area inundated by 1% annual chance flooding, for which BFEs have been
determined.
Zone AH -
An area inundated by 1% annual chance flooding (usually an area of ponding),
for which BFEs have been determined; flood depths range from 1 to 3 feet.
Zone AO -
An area inundated by 1% annual chance flooding (usually sheet flow on sloping
terrain), for which average depths have been determined; flood depths range
from
1 to 3 feet.
Zone AR -
.An area inundated by flooding, for which BFEs or average depths have
been
determined. This is an area that was previously, and will again,
be protected from
the 1% annual chance flood by a Federal flood protection system whose
restoration is Federally funded and underway
Zone A1-A30 - An area inundated by 1%
annual chance flooding, for which BFEs have been
determined.
.
Area Not
Included
(ANI),(N) -
An area that is located within a community or county that is not mapped
on any
published FIRM.
Zone D -
An area of undetermined but possible flood hazards.
Undescribed
(UNDES) -
Area of Undesignated Flood Hazard. A body of open water, such as
a pond,lake,
ocean, etc., located within a community's jurisdictional limits, that has
no defined
flood hazard.
Zone VE -
An area inundated by 1% annual chance flooding with velocity hazard
(wave action); BFEs have been determined.
Zone V(1-30)
- Costal flood with velocity hazard
(wave action); BFEs have not been determined.
FWIC
- An area where
the floodway is contained within the channel banks and the channel
is too narrow to show to scale. An arbitrary channel width of
3 meters is shown.
BFEs are not shown in this area, although they may be reflected on the
corresponding profile. (Floodway Contained in Channel)
100IC -
An area where the 1% annual chance flooding is contained within the channel
banks and the channel is too narrow to show to scale. An arbitrary
channel width
of 3 meters is shown. BFEs are not shown in this area, although they
may be
reflected on the corresponding profile. (1% Annual Chance Flood Discharge
Contained in Channel)
500IC -
An area where the 0.2% annual chance flooding is contained within the channel
banks and the channel is too narrow to show to scale. An arbitrary
channel width
of 3 meters is shown. ( 2% Annual Chance Flood Discharge Contained
in Channel)
