- 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_OCT17 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 FIRM Database presents the flood risk
information depicted on the FIRM in a digital format suitable for use in electronic
mapping applications. The FIRM Database serves to archive the information
collected during the Flood Risk Project.

** 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 NFHL reflects 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. Generally, regulatory water surface elevations and/or
regulatory floodways are published only for developed or developing areas of
communities. For areas where little or no development is expected to occur, FEMA
may generate flood risk data without published water surface elevations. Typically,
only drainage areas that are greater than one square mile and with an average of
one foot of flood depth or greater are studied. Note: The NFHL reflects the most
current information available when the distribution data set was created. Currently,
not all areas of a State or Territory have effective FIRM Database data. As a result,
users may need to refer to the effective FIRM for effective flood hazard information.

The NFHL consists of vector files and associated attributes produced in
conjunction with the hardcopy FEMA FIRM. The published effective FIRM and
FIRM Database 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 Standards for Flood Risk Analysis and
Mapping. 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 the individual FIRM Database
components of the NFHL was also performed.

comparing the computed flood elevation to the ground elevation at the mapped
floodplain boundary. The tolerance for how precisely the flood elevation and the
ground elevation must match varies based on the flood risk class, which is a
function of population, population density, and/or anticipated growth in floodplain
areas. A horizontal accuracy of +/- 38 feet is used to determine the compliance with
the vertical tolerances defined for each risk class. The range of differences
between the ground elevation (defined from the topographic data used for the Flood
Risk Project) and the computed flood elevation is between +/- 1.0 foot at the 95%
confidence interval for areas with high population within the floodplain and/or high
anticipated growth and Special Flood Hazard Areas (SFHAs) with high flood risk to
+/- one-half the contour interval at the 85% confidence interval for areas with low
population and densities within the floodplain and small or no anticipated growth
and SFHAs with low flood risk. Independent quality control testing of the individual
FIRM Database components of the NFHL was also performed.

The NFHL dataset is a compilation of effective FIRM Databases
(a collection of the digital data that are used in GIS systems for creating new Flood
Insurance Rate Maps) and Letters of Map Change (Letters of Map Amendment and
Letters of Map Revision only) that create a seamless GIS data layer for a State or
Territory. It is updated on a monthly basis. The FIRM Databases are compiled in
conjunction with the hardcopy FIRMs and the final FIS reports. The specifics of the
hydrologic and hydraulic analyses performed are detailed in the FIS reports available
for each jurisdiction. 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 FIRM publication and checked for accuracy and compliance
with FEMA standards. As new FIRM Databases are received the individual FIRM
layers are sewn into the nationwide layers of the NFHL. LOMRs for the FIRM
Databases in the NFHL are cut directly into the NFHL data layers as they are being
produced and finalized.

Duplicate Removal Process for Brevard County, impacting the following datasets; BFE, CBRS, FLDHAZ & PANEL.
It was noted that duplicate records existed for BREVARD COUNTY where ID = 12009C_*
- Reviewed the duplicate features where the dataset specific unique id count was greater than 1.
Dataset specific unique ids are as follows:
- BFE = BFE_FN_ID
- CBRS = CBRS_ID
- FLDHAZ = FLD_AR_ID
- PANEL = FIRM_ID
- Summarized on Dataset specific unique ids with MAX and Min boxes check for AUTOID and AREA.
- Exported the duplicates and checked to make sure the areas of each suspect duplicate matched (they did).
- Joined this table back to the full dataset on the Max AUTOID field.
- Ran a selection to grab just these records where the Max AUTOID matched.
- Ran Switch selection set and exported out the full dataset without the extra duplicate records.
- This process was used to clean all four datasets impacted.

Source Citation. Abbreviation used in the metadata file when describing the source information for the S_Fld_Haz_Ar table. Normally, the flood hazard area polygon will be divided to distinguish areas modified by the most recent revision from areas based on the effective FIRM prior to the most recent revision. Revisions and sources prior to the most recent revision will not be tracked for individual polygons in the flood hazard areas table in the standard database.

The DFIRM Database is made up of several data themes containing both spatial
and attribute information. These data together represent the current flood risk for the
subject area as identified by FEMA. The attribute tables include SFHA locations,
flood zone designations, BFEs, political entities, cross-section locations, FIRM panel
information, and other data related to the NFIP.
Table containing attribute information associated with the data set.

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
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center
shall not be liable for any damages suffered as a result of using,
modifying, contributing or distributing the materials.
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
scale and accuracy, see our webpage at:
