The property is within Zone A. The lowest floor is 437.6.
BFE is 438.4 (Krush) or 438.7 (FEMA)
To be removed from the floodplain, the lowest floor must be at least 12" above BFE (439.4 or
439.7)
Zone A
Zone A is the flood insurance rate zone used for l-percent-annual-chance (base flood)
floodplains that are determined for the Flood Insurance Study (FIS) by approximate methods of
analysis. Because detailed hydraulic analyses are not performed for such areas, no Base Flood
Elevations (BFEs) or depths are shown in this zone. Mandatory flood insurance purchase
requirements apply.
Base flood. The flood having a one percent chance of being equaled or exceeded in any given
year. This is the regulatory standard also referred to as the "lOO-year flood." The base flood is
the national standard used by the NFIP and all Federal agencies for the purposes of requiring
the purchase of flood insurance and regulating new development. Base Flood Elevations (BFEs)
are typically shown on Flood Insurance Rate Maps (FIRMs).
Base Flood Elevation (BFE). The flood having a one percent chance of being equaled or
exceeded in any given year. This is the regulatory standard also referred to as the "lOO-year
flood." The base flood is the national standard used by the NFIP and all Federal agencies for the
purposes of requiring the purchase of flood insurance and regulating new development. Base
Flood Elevations (BFEs) are typically shown on Flood Insurance Rate Maps (FIRMs).
Elevation. Commuriities must require that all new construction and substantial improvements
of residential structures within Zones Al-30, AE and AH Zones on the commuriity"s Flood
Insurance Rate Map (FIRM) have the lowest floor (including basement) elevated to or above the
Base Flood Eelevation (BFE). Common elevation techniques include elevation on file, elevation
on piles, piers or columns, and elevation on extended foundation walls such as on a crawl
space.
In areas designated as Zone A, the commuriitv must obtain, review, and reasonably utilize BFE
data available from a Federal, State, or other source and use these data as criteria for requiring
that new construction and substantial improvements of residential structures have the lowest
floor (including basement) elevated to or above the BFE.
All new construction and substantial improvement in Zones Vl-30, VE, and also Zone V (if BFE
data is available), must be elevated on pilings and columns so that the bottom of the lowest
horizontal structural member of the lowest floor (excluding the pilings or columns) is elevated
to or above the BFE.

For residential structures in AO Zones, the lowest floor (including basement) must be elevated
at least as high as the depth number specified in feet on the community"s map, or at least two
feet if no number is specified.
. LOMA Requests Involving One or More Structures: For a LOMA to be issued by
FEMA to remove one or more structures from the SFHA, the NFIP regulations require
that the lowest adjacent grade (the lowest ground touching the structure) be at or above
the BFE.
. LOMA Requests Involving One or More Lots: For a LOMA to be issued by FEMA to
remove one or more entire lots from the SFHA, the NFIP regulations require that the
lowest point on the lot(s) must be at or above the BFE.
. LOMR-F Requests Involving One or More Structures: For a LOMR-F to be issued by
FEMA to remove the structure from the SFHA, the NFIP regulations require that the
lowest adjacent grade of the structure be at or above the BFE. The participating
community must also determine that the land and any existing or proposed structures to
be removed from the SFHA are "reasonably safe from flooding."
. LOMR-F Requests Involving One or More Lots: For a LOMR-F to be issued by
FEMA to remove the entire lot and structure, both the lowest point on the lot and the
lowest floor of the structure must be at or above the I -percent-annual-chance flood
elevation.
