Abstract: This table is required for any Digital Flood Insurance Rate Map database where cross sections are shown on the Flood Insurance Rate Map (FIRM). Normally any FIRM that has associated flood profiles has cross sections. The S_XS table contains information about cross section lines. A spatial file with locational information also corresponds with this data table. These lines represent the locations of channel surveys performed for input into the hydraulic model used to calculate flood elevations. These locations are also shown on the Flood Profiles in the Flood Insurance Study (FIS) report and can be used to cross reference the Flood Profiles to the planimetric depiction of the flood hazards. All cross sections for which a spatial location is available should be included

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Description:
Abstract:
This table is required for any Digital Flood Insurance Rate Map database where cross sections are shown on the Flood Insurance Rate Map (FIRM). Normally any FIRM that has associated flood profiles has cross sections.
The S_XS table contains information about cross section lines. A spatial file with locational information also corresponds with this data table. These lines represent the locations of channel surveys performed for input into the hydraulic model used to calculate flood elevations. These locations are also shown on the Flood Profiles in the Flood Insurance Study (FIS) report and can be used to cross reference the Flood Profiles to the planimetric depiction of the flood hazards. All cross sections for which a spatial location is available should be included

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.

Use constraints:
The hardcopy FIRM and DFIRM and the accompanying FISs are the official designation of SFHAs and
Base Flood Elevations (BFEs) for the NFIP.  For the purposes of the NFIP, changes to the flood risk
information published by FEMA may only be performed by FEMA and through the mechanisms established
in the NFIP regulations (44 CFR Parts 59-78).
These digital data are produced in conjunction with the hardcopy FIRMs and generally matches the
hardcopy map exactly.  However the hardcopy flood maps and flood profiles are the authoritative
documents for the NFIP.
Acknowledgement of FEMA would be appreciated in products derived from these data.

Data Quality Information:


Attribute accuracy:
Attribute accuracy report:
The DFIRM Database consists of countywide vector files and associated attributes produced in conjunction
with the hard copy FEMA FIRM. The published effective FIRM and DFIRM maps 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.  Attribute 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.
To obtain more detailed information in areas where Base Flood Elevations (BFEs) and/or floodways have been
determined, users are encouraged to consult the Flood Profiles and Floodway Data and/or Summary of
Stillwater Elevations tables contained within the FIS report that accompanies this DFIRM database.
Users should be aware that BFEs shown in the S_BFE table represent rounded whole-foot elevations.
These BFEs are intended for flood insurance rating purposes only and should not be used as the sole source
of flood elevation information.  Accordingly, flood elevation data presented in the FIS report must be used
in conjunction with the FIRM for purposes of construction and/or floodplain management.  The 1-percent-annual-
chance water-surface elevations shown in the S_XS table match the regulatory elevations shown in
the FIS report.

ESRI feature type: Simple, Geometry: Polyline, Topology:

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 FIS and FIRM are the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance Program (NFIP). This DFIRM includes data previously published by FEMA in the following Flood Insurance Studies: Leon County (Unincorporated Areas), Florida, 19971119, City of Tallahassee, Florida 19971119. The sources of authority for this FIS are the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973. This FIS was prepared to include the incorporated communities within Leon County into a countywide FIS. Information on the authority and acknowledgments for each jurisdiction included in this countywide FIS, as compiled from their previously printed FIS reports, is shown below. Leon County (Unincorporated Areas): the hydrologic and hydraulic analyses for the FIS report dated June 15, 1982, were prepared by the U.S. Geological Survey (USGS), for the Federal Emergency Management Agency (FEMA), under Inter-Agency Agreement No. IAA-H-17-75, Project Order No. 9. That work was completed in May 1978. Tallahassee, City of: the hydrologic and hydraulic analyses for the FIS report dated December 6, 1976, were prepared by the USGS, for the Federal Insurance Administration, under Inter-Agency Agreement No. IAA-H-3-73, Project Order No. 3. The hydrologic and hydraulic analyses for the FIS report dated August 5, 1986, were prepared by the USGS. For the November 19, 1997, FIS, revised hydrologic and hydraulic analyses for Alford Arm, Alford Arm Tributary, Bradford Brook, Cascade Lake, East Drainage Ditch, Fords Arm Tributary, Grassy Lake, Gum Creek, Lake Bradford, Lake Hiawatha, Lake Lafayette (upper and lower), Lake Overstreet Tributary, McCord Park Pond Drainage Ditch, Meginnis Arm Tributary, Middle Drainage Ditch, Munson Slough, North Branch Gum Creek, Northeast Drainage Ditch, Northwood Mall Drainage Ditch, Ochlockonee River, Park Avenue Ditch, Piney Z Lake, Richview Road Ditch, Royal Oaks Creek, San Luis Branch, St. Augustine Branch, West Branch Gum Creek, West Drainage Ditch, West Drainage Ditch Tributary, and Windrush Apartments Ditch were prepared by the USGS. That work was completed in 1987. For the April 3, 2002, preliminary FIS, the hydrologic and hydraulic analyses for Alford Arm Tributary were performed by Post, Buckley, Schuh & Jernigan (PBS&J). This work was completed in March 2001. The analyses for Northeast Drainage Ditch were performed by Singhofen & Associates, Inc. This work was completed in May 2000. For this revision, the hydrologic and hydraulic analyses for East Drainage Ditch were performed by Dyer, Riddle, Mills & Precourt, Inc. (DRMP). This work was completed in July 2001. The analyses for West Drainage Ditch were performed by Engineering Methods and Applications (EMA) (a division of Watershed Concepts). This work was completed in December 2002. The digital base map information files for this countywide FIS were provided by the City of Tallahassee, Stormwater Management Department, City Hall, 300 South Adams Street, Tallahassee, Florida 32301; and the Leon County Geographic Information Systems Department, 301 South Monroe Street, Tallahassee, Florida 32301. These files were photogrammetrically compiled at scales of 1"=200' (urban areas) and 1"=400' (rural areas) from aerial photographs. These files were collected in Florida State Plane Coordinates (north zone) referenced to the National Geodetic Vertical Datum of 1929 (NGVD 29). Base map features in the Appalachicola National Forest were derived from USGS 1:100,000 scale Digital Line Graph files. Subsequent modifications to the road network were based on the 1994 Street Atlas of Leon County supplied by the City of Tallahassee. The digital FIRM was produced using Universal Transverse Mercator coordinates referenced to the North American Datum of 1927, and the Clarke 1866 spheroid. This FIS covers the geographic area of Leon County, Florida. The area of study is shown on the Vicinity Map. All or portions of the following flooding sources were studied by detailed methods. Limits of detailed study are indicated on the Flood Profiles and on the FIRM.

The LOMR dated April 20, 2000, was issued for Park Avenue Ditch. The revision to the FIS and FIRM reflected more up-to-date corporate limits for the City of Tallahassee. The areas studied by detailed methods were selected with priority given to all known flood hazard areas and areas of projected development and proposed construction. All or portions of numerous flooding sources in the county were studied by approximate methods. Approximate analyses were used to study those areas having a low development potential or minimal flood hazards. The scope and methods of study were proposed to, and agreed upon by, FEMA and the affected communities.
