- Abstract:
-
This dataset contains information about the Base Flood Elevations (BFE) within a study area. BFE lines indicate the rounded whole-foot water surface elevation of the 1-percent-annual-chance flood.
The spatial elements representing BFE features are lines extending from Special Flood Hazard Area (SFHA) boundary to SFHA boundary. The BFE lines will have no visible gaps or overshoots between the SFHA boundary and the end of the BFE line at the publication scale of the DFIRM. However, the ends of the BFE lines are not necessarily snapped precisely to the SFHA boundary. Each BFE is represented by a single line. The Base Flood Elevation (BFE) information is required for any digital data where BFE lines will be shown on the corresponding Flood Insurance Rate Map (FIRM). Normally if there are any riverine AE zones, BFE lines are required. While BFE lines are depicted as wavy lines on the hardcopy FIRM, they should be primarily straight lines in the spatial data, although they may bend consistent with procedures described in Volume 1 of these Guidelines.
The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting
data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance
flood event (100 year), the 0.2-percent-annual-chance flood event (500 year), and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps
(FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data,
where available. The FISs and FIRMs are published by FEMA. This dataset is an update to the DFIRM_BFE_MAY12.shp layer.
- Purpose:
-
The FIRM is the basis for floodplain management, mitigation, and insurance activities for the National
Flood Insurance Program (NFIP). Insurance applications include enforcement of the mandatory purchase
requirement of the Flood Disaster Protection Act, which "... requires the purchase of flood insurance by
property owners who are being assisted by Federal programs or by Federally supervised, regulated or
insured agencies or institutions in the acquisition or improvement of land facilities located or to be located
in identified areas having special flood hazards," Section 2 (b) (4) of the Flood Disaster Protection Act of
1973. In addition to the identification of Special Flood Hazard Areas (SFHAs), the risk zones shown on the
FIRMs are the basis for the establishment of premium rates for flood coverage offered through the NFIP.
The DFIRM Database presents the flood risk information depicted on the FIRM in a digital format suitable
for use in electronic mapping applications. The DFIRM database is a subset of the Digital FIS database that
serves to archive the information collected during the FIS.

What Is an LFD?
A Letter of Final Determination (LFD) is a letter the Federal Emergency
Management Agency (FEMA) sends to the Chief Executive Officer of a community
stating that a new or updated Flood Insurance Rate Map (FIRM) or Digital Flood
Insurance Rate Map (DFIRM) will become effective in 6 months. The letter also
notifies each affected flood prone community participating in the National Flood
Insurance Program (NFIP) that it must adopt a compliant floodplain management
ordinance by the map effective date to remain participants in good standing in the
NFIP.

** The following FEMA DFIRM information is from the frm_gsalb.pdf **
Table: S_BFE
The Base Flood Elevation (BFE) table is required for any digital data where BFE
lines will be shown on the corresponding Flood Insurance Rate Map (FIRM).
Normally if there are any riverine AE zones, BFE lines are required.
The S_BFE table contains information about the BFEs within a study area. A
spatial file with locational information also corresponds with this data table. BFE
lines indicate the rounded whole-foot water surface elevation of the
1-percent-annual-chance flood.
The spatial elements representing BFE features are lines extending from Special
Flood Hazard Area (SFHA) boundary to SFHA boundary. The BFE lines will have
no visible gaps or overshoots between the SFHA boundary and the end of the
BFE line at the publication scale of the DFIRM. However, the ends of the BFE
lines are not necessarily snapped precisely to the SFHA boundary. Each BFE is
represented by a single line. While BFE lines are depicted as wavy lines on the
hardcopy FIRM, they should be primarily straight lines in the spatial data, although
they may bend consistent with procedures described in Volume 1 of these
Guidelines.

-
When FEMA revises an FIS, adjacent studies are checked to ensure agreement between flood elevations at
the boundaries. Likewise flood elevations at the confluence of streams studied independently are checked
to ensure agreement at the confluence. The FIRM and the FIS are developed together and care is taken to
ensure that the elevations and other features shown on the flood profiles in the FIS agree with the
information shown on the FIRM. However, the elevations as shown on the FIRM are rounded whole-foot
elevations. They must be shown so that a profile recreated from the elevations on the FIRM will match
the FIS profiles within one half of one foot.
- Completeness_Report:
-
Data contained in the DFIRM Database files reflect the content of the source materials. Features may have
been eliminated or generalized on the source graphic, due to scale and legibility constraints. With new
mapping, FEMA plans to maintain full detail in the spatial data it produces. However, older information is
often transferred from existing maps where some generalization has taken place.
Flood risk data are developed for communities participating in the NFIP for use in insurance rating and for
floodplain management. Flood hazard areas are determined using statistical analyses of records of river
flow, storm tides, and rainfall; information obtained through consultation with the communities; floodplain
topographic surveys; and hydrological and hydraulic analysis. Both detailed and approximate analyses are
employed. Generally, detailed analyses are used to generate flood risk data only for developed or
developing areas of communities. For areas where little or no development is expected to occur, FEMA uses
approximate analyses to generate flood risk data. Typically, only drainage areas that are greater than one
square mile are studied.

The DFIRM Database consists of countywide vector files and associated attributes produced in conjunction
with the hardcopy FEMA FIRM. The published effective FIRM and DFIRM are issued as the official designation
of the SFHAs. As such they are adopted by local communities and form the basis for administration of the
NFIP. For these purposes they are authoritative. Provisions exist in the regulations for public review,
appeals and corrections of the flood risk information shown to better match real world conditions. As with
any engineering analysis of this type, variation from the estimated flood heights and floodplain boundaries
is possible. Details of FEMA's requirements for the FISs and flood mapping process that produces these data
are available in the Guidelines and Specifications for Flood Hazard Mapping Partners. Horizontal accuracy
was tested by manual comparison of source graphics with hardcopy plots and a symbolized display on an
interactive computer graphic system.
Independent quality control testing of FEMA's DFIRM database was also performed.

The DFIRM Database is compiled in conjunction with the hardcopy FIRM
and the final FIS report. The specifics of the hydrologic and hydraulic
analyses performed are detailed in the FIS report. The results of these
studies are submitted in digital format to FEMA. These data and unrevised
data from effective FIRMs are compiled onto the base map used for
DFIRM publication and checked for accuracy and compliance with

GeoPlan Center Process Steps:
On June 8th, 2011 it was noted that there was a projection issue with the
DFIRM layer for Okaloosa County. The DFIRM FEMA Okaloosa County
layer was compared with another DFIRM layer available for download from the
county. Upon comparison it was noted that there was a shift in the dataset. The
layer was then extensively reviewed and it was determined that the layer in FGDL
was not properly projected due to an incompatibility issue between the original
projection file and ESRI software. More specifically, ESRI ArcGIS software does
not properly recognize the original DFIRM projection file, and hence does not
perform both transformations necessary to project from the DFIRM projection
(NAD27 UTM) to the FGDL Albers projection (NAD83 HARN Florida).
To solve the projection file incompatibility issue, GeoPlan first redefined the
originally downloaded, non-projected DFIRM layer to a matching projection file
supplied by ESRI. Upon reprojecting with this new projection file, the two
transformations properly occurred and the layer then accurately aligned with the
data Okaloosa County has available for download.
Please note: redefining a layer's original projection is not part of GeoPlan's normal
QAQC procedures and is only done when a layer does not have an associated
projection file (which is rare).
Because of this projection issue, GeoPlan reviewed the projections and spatial
accuracy of all BFE DFIRM county layers distributed in FGDL. Upon review, it was
noted that the following counties had the same incompatibility issue with their
original projection files, resulting in a shift of spatial features: Bay County,
Charlotte County, Lake County, Osceola County, and St Johns County.
Using the incompatible projection files, the average shift measurements for these
counties is as follows:
Bay County [county-wide average shift = 0.39 meters]
- Original Projection: NAD27 UTM, Zone 16 North, Meter
Charlotte County [county-wide average shift = 0.39 meters]
- Original Projection: NAD83 UTM, Zone 17 North, Meter
Lake County [county-wide average shift = 37 meters]
- Original Projection: NAD27 UTM, Zone 17 North, Meter
Okaloosa County [county-wide average shift = 21 meters]
- Original Projection: NAD27 UTM, Zone 16 North, Meter
Osceola County [county-wide average shift = 37 meters]
- Original Projection: NAD27 UTM, Zone 17 North, Meter
St. Johns County [county-wide average shift = 0.39 meters]
- Original Projection: NAD83 UTM, Zone 17 North, Meter
For Bay County, it was later determined that while their projection file indicated
a datum of NAD27, the data was actually in NAD83 projection, which resulted in
a much smaller shift. Please note that Bay County was still re-downloaded and
re-projected.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.
Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center

A note about data scale:
Scale is an important factor in data usage. Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.
Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
