ZONE TYPES
C-ZONE:
Areas of minimal Flooding. Considered a non-flood zone and there are no special requirements for building in this zone.
B-ZONE:
Areas between 100 and 500 year flood, subject to 100 flooding with
average depths less than 1 foot.
There are no special requirements for building within this
zone.
A-ZONE:
Areas of 100-year flood. Base
flood elevations and flood hazard factors not determined. The requirements for this area are; all habitable structures are
elevated 24 inches above grade to the lowest horizontal member (girder
/ joist).
A1-A30
(NUMBERED A-ZONE): Areas of 100-year flood, base flood elevations
and flood hazard factors determined. Structures in this zone must be elevated to
the base flood elevation shown on the FEMA Flood maps. Numbered A zones require a benchmark survey
before a permit can be issued and an elevation certificate before
power will be turned on. The
benchmark survey and elevation certificate must come from a Florida
registered surveyor.
V1-V30
(VELOCITY ZONE): Areas
of 100-year coastal flood with velocity (wave action), base flood
elevations and flood hazard factors determined.
Structures in these zones must be designed by a Florida registered
Engineer or Architect and be elevated to the base flood elevation
found on the FEMA flood maps. These
zones require a benchmark survey before a permit can be issued and
an elevation certificate before power will be turned on.
