- Abstract:
-
This dataset contains information about the Coastal Barrier Resources System Boundaries (CBRS) within a study area. The Coastal Barrier Resources Act (CBRA) of 1982 established the John H. Chafee Coastal Barrier Resources System (CBRS), comprised of undeveloped coastal barriers along the Atlantic, Gulf, and Great Lakes coasts. The law encourages the conservation of hurricane prone, biologically rich coastal barriers by restricting Federal expenditures that encourage development, such as Federal flood insurance through the National Flood Insurance Program. CBRA is a free-market approach to conservation. These areas can be developed, but Federal taxpayers do not underwrite the investments. CBRA saves taxpayer dollars and encourages conservation at the same time. CBRA has saved over $1 billion and will save millions more in the future. Approximately 3.1 million acres of land and associated aquatic habitat are part of the CBRS. The Fish and Wildlife Service maintains the repository for CBRA maps enacted by Congress that depict the CBRS. The Service also advises Federal agencies, landowners, and Congress regarding whether properties are in or out of the CBRS, and what kind of Federal expenditures are allowed in the CBRS.
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_CBRS_JUL11.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 floodprone 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_CBRS
This table only applies to coastal areas that have specially protected areas
designated by Congress on John H. Chafee Coastal Barrier Resources System
(CBRS) maps. Authoritative CBRS boundary locations are shown on these maps
administered by the U.S. Fish and Wildlife Service. Normally these areas are
already shown on existing Federal Emergency Management Agency (FEMA) maps
for the area. CBRS areas have restrictions on Federal funding (including flood
insurance coverage) after specified dates for new or substantially improved
structures. See Section 2.2 and Appendix K of these Guidelines for more detailed
information about CBRS areas.
The S_CBRS table contains information about the CBRS areas within the study
area, if applicable. A spatial file with locational information also corresponds with
this data table.
The spatial elements representing CBRS features are closed polygons. Each
contiguous CBRS area of the same CBRS_TYP and same CBRS_DATE must be
a single polygon.
This is a Standard DFIRM Database table.
What are Coastal Barriers?
Coastal barriers are unique land forms that provide protection for diverse aquatic
habitats and serve as the mainland's first line of defense against the impacts of
severe coastal storms and erosion. Located at the interface of land and sea, the
dominant physical factors responsible for shaping coastal land forms are tidal
range, wave energy, and sediment supply from rivers and older, pre-existing
coastal sand bodies. Relative changes in local sea level also profoundly affect
coastal barrier diversity.
Coastal barriers:
* Consist primarily of unconsolidated sediments (sand, gravel, etc.);
* are subject to wind, wave, and tidal energies;
* are subject to the impacts of coastal storms and sea-level rise;
* buffer the mainland from the impact of storms;
* include associated landward aquatic habitats that are protected from direct
wave attack by the fastland (non-wetland) portion of the coastal barrier; and
* protect and maintain productive estuarine systems which support the Nation's
fishing and shellfishing industries;
Types of Coastal Barriers
Coastal barriers may be described by their relationships to the mainland as bay
barriers, tombolos, barrier spits, and barrier islands. Additional areas which function
as coastal barriers include dune and beach barriers, and fringing mangroves. The
term "mainland" includes the continental land mass as well as large islands such
as Long Island, New York and the Hawaiian Islands. Definitions of the various
kinds of coastal barriers follow.
* Bay barriers - coastal barriers that connect two headlands, and enclose a
pond, marsh, or other aquatic habitat. The terms bay mount bar and bay bar are
synonymous.
* Tombolos - sand or gravel beaches which connect one or more offshore
islands to each other or to the mainland. The terms connecting bar, tie bar, and
tying bar are synonymous.
* Barrier spits - coastal barriers that extend into open water and are attached to
the mainland at only one end. They can develop into a bay barrier if they grow
completely across a bay or other aquatic habitat. On the other hand, bay barriers
can become spits if an inlet is created.
* Barrier islands - coastal barriers completely detached from the mainland.
Barrier spits may become barrier islands if their connection to the mainland is
severed by creation of a permanent inlet. The barrier island represents a broad
barrier beach, commonly sufficiently above high tide to have dunes, vegetated
zones, and wetland areas.
* Dune or beach barriers - broad sandy barrier beaches, with hills or ridges of
sand formed by winds, which protect landward aquatic habitats.
* Fringing mangroves - bands of mangrove along subtropical or tropical
mainland shores in areas of low wave energy. Many of these areas are located
behind coral reefs, which together with the mangroves themselves, provide
significant protection for the mainland from storm impact.
Location of Coastal Barriers
Coastal barriers occur on all the coastlines of the United States. One of the
longest and best defined chains of coastal barriers in the world occurs along the
United States shoreline bordering the Atlantic Ocean and the Gulf of Mexico. This
chain contains over 400 barriers and totals about 2,700 miles of shoreline. The
coastal barriers from Maine to Texas show a high degree of regional diversity,
controlled by differences in climate and in the physical processes shaping barrier
shorelines. Long, continuous barriers with small ebb-tidal deltas are produced by
longshore currents along wave-dominated coasts. These barriers are typified by
the coastal barrier islands along the south Texas coast which are long, generally
narrow, and cut by widely separated tidal inlets with large sand accumulations in
the back-barrier bays, and small or nonexistent seaward shoals. Similar barrier
islands are also found in parts of Louisiana, the Florida panhandle, southeast
Florida, North Carolina's Outer Banks, the south shore of Long Island, and the
Cape Cod segment of the Massachusetts coast. Tide-dominated coastlines
support large ebb-tidal deltas. The Georgia coastal barrier islands typify a
tide-dominated coastline: they are relatively short and stubby and are separated by
stable tidal inlets with an average spacing of 9 miles. Tide-dominated barriers also
occur in northeast Florida, most of South Carolina's coast, along the Delmarva
Peninsula, Massachusetts, and in some areas of Louisiana and Texas.
Secondary Barriers
If a suitable sediment source and sufficient wind, waves, and tidal energy exist, a
secondary barrier may occasionally form behind the seaward coastal barrier.
Secondary barriers are located in large, well-defined bays or in lagoons on the
mainland side of coastal barrier systems. These barriers are maintained primarily by
internally generated wind waves rather than open ocean waves. Consequently,
secondary barriers are generally smaller and more ephemeral than barriers along the
open coast. Nonetheless, these barriers are formed of unconsolidated sediments
just like most oceanic barriers and, more importantly, they also protect vital fish and
wildlife habitat and provide substantial protection for the mainland during major storms.
Value of Coastal Barriers
Coastal barriers provide invaluable services that are the foundations of a strong
economy and healthy environment. They offer habitats that support a variety of fish
and wildlife, protect mainland communities from severe storms, serve as popular
vacation destinations, and support local economies.
Coastal Barriers and Natural Resources
Coastal barriers protect the aquatic habitats between the barrier and the mainland
which contain resources of extraordinary scenic, scientific, recreational, natural,
historic, and economic value. Together with their adjacent wetland, marsh, estuarine,
inlet, and nearshore water habitats, coastal barriers support a tremendous variety of
organisms. Millions of fish, shellfish, birds, mammals, and other wildlife depend on
barriers and their associated wetlands for vital feeding, spawning, nesting, nursery,
and resting habitat. These habitats are also critically important for many species
harvested in the Nation's commercial fish and shellfish industries. The barrier and its
associated habitats are one ecological system, and the health and productivity of the
entire system depend on the rational use of all the component parts.
Coastal Barriers and Severe Storms
Under normal weather conditions, only aquatic habitats immediately adjacent to
coastal barriers are exposed to direct wave attack. However, major coastal storms
routinely affect the entire landward aquatic habitat. This habitat survives major storms
because coastal barriers receive the brunt of the ocean's energies. Storm waves break
on the barrier beach, leaving a diminished wave to travel into the wetland. At the same
time, the wetland stores storm flood waters, easing the flood pressure on the mainland.
Without extensive sand beaches protecting many bluffs and terraces, damages from
violent storms would be much greater. Sand acts as a brake or drag on waves. Where
there are barrier beaches fronting embayments, the sand absorbs the energy much as it
does at the base of cliffs. The principal danger to beaches and barriers is not intense
storms but a steady reduction in the sand supply caused by dams on tributary streams
and the diversion or interruption of littoral transport along the seaward edge of beaches
and barriers by bulkheads, groins, and jetties. In some situations, mining of beach sand
has contributed to the problem. Spits and low-lying barrier beaches survive severe storms
with relatively slight effects as long as there is a supply of sand available to restore the
beach. A severe storm is a short-term phenomenon, repeating the annual cycle of
changing width and slope of the beach within a few hours. Sometimes a spit is eroded
back or shortened and the dunes reduced or moved, but the sand begins to build up
again towards its equilibrium condition almost as soon as the storm ends. The entrance to
a bay and/or river mouth may be relocated or shoaled, but this sometimes also happens
without storms. Shoaling of harbor entrances may be dangerous to navigation and require
dredging to restore an entrance channel.
Development of Coastal Barriers
Besides bearing the brunt of impacts from storms and erosion, most coastal barriers are
made of unconsolidated sediments (sand, gravel, etc.). This geological composition
alone makes them highly unstable areas on which to build. Despite their instability, many
coastal barriers have been developed. In the past, this development was encouraged
by the availability of Federal flood insurance and other types of Federal financial assistance.
Through its unique free-market approach to conservation, the Coastal Barrier
Resources Act has been instrumental in ensuring that the Federal government does not
encourage the development of these coastal barrier habitats.

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.

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

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
makes no representations or warranties about the quality or suitability

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
