Federal Emergency Management Agency 20171001 NFHL Florida Data Product ID: NFHL_12_20171006, Version 1.1.1.0, ESRI FGDB 9.3 raster digital data 500 C Street SW, Washington, DC, 20472, US Federal Emergency Management Agency State of Florida www.fgdl.org Federal Emergency Management Agency 20171006 1.1.1.0 GIS Data Project/Collection Geospatial Data Presentation Form FEMA-NFHL Washington, D.C. Federal Emergency Management Agency https://msc.fema.gov This dataset represents areas within the FEMA 100-year floodplain. This dataset was derived from the Digital Flood Insurance Rate Map (DFIRM) Database which depicts flood risk information. 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. 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.

However, no methodology was performed by GeoPlan to correct for these issues. For more information on FEMA's Final Data Structure concerning sliver polygons please see below. The FEMA report frm_gsal.pdf states the following regarding sliver polygons. L.3.5.2 Topology Vector data files must meet the following data structure requirements: * Area spatial features for a given theme must cover the entire study area without overlaps, underlaps or sliver polygons between adjacent polygons. Next Deleted the following 3 features due to spatial errors: 12123C_10583 (Duplicate Polygon), 12111C_1676 (Zero Area), 12097C_502 (Negative Area). It was noted that 45 features had vertex counts greater than 500,000. Features with large vertex counts are known to cause database analysis crashes and errors. The ArcGIS Dice Tool subdivides a feature into smaller features based on a specified vertex limit. This tool is intended as a way to subdivide extremely large features that cause issues with drawing, analysis, editing, and/or performance but are difficult to split up with standard editing and geoprocessing tools. This tool should not be used in any cases other than those where tools are failing to complete successfully due to the size of features. Source: http://desktop.arcgis.com/en/arcmap/latest/tools/data-management-toolbox/dice.htm The following 45 features were subdivided using the ArcGIS Dice Tool with a vertex limit of 350,000.

It is not the flood that will occur once every 100 years. Rather, it is the flood that has a 1-percent chance of being equaled or exceeded each year. Thus, the 100-year flood could occur more than once in a relatively short period of time or even within the same month. Because this term is misleading, FEMA has also defined it as the "1-percent-annual-chance flood." The "1-percent-annual-chance flood" is the term that is now used by most federal and state agencies and by the National Flood Insurance Program. SOURCE: https://www.fema.gov/frequently-asked-questions/insurance-professionals-lenders-frequently-asked-questions -------------------------------------------------------------------------------- ** The following FEMA DFIRM information is from the frm_gsalb.pdf ** Table: S_Fld_Haz_Ar This table is required for all draft Digital Flood Insurance Rate Map data. The S_Fld_Haz_Ar table contains information about the flood hazards within the study area. A spatial file with locational information also corresponds with this data table. These zones are used by the federal Emergency Management Agency (FEMA) to designate the Special Flood Hazard Area (SFHA) and for insurance rating purposes. These data are the flood hazard areas that are or will be depicted on the Flood Insurance Rate Map (FIRM). A spatial file with locational information also corresponds with this data table. The spatial elements representing the flood zones are polygons. The entire area of the jurisdiction(s) mapped by the FIRM should have a corresponding flood zone polygon. There is one polygon for each contiguous flood zone designated. This is a modified Standard DFIRM Database table that includes Standard DFIRM Database items and Enhanced Database items. All items after SOURCE_CIT are Enhanced. Table: D_Zone Where the 1-percent-annual-chance flood or the 0.2-percent-annual-chance flood is contained in a culvert or channel, a corresponding feature appears in the S_Fld_Haz_Ar table only if an SFHA or 0.2-percent-annual-chance flood zone is shown on the FIRM in this area. In general, these culverts and channels are to be represented in the general structure table regardless of how the flood insurance risk zones are depicted. So, if these structures are shown on the FIRM as a dashed line passing through a Zone X, no corresponding flood insurance risk zone is shown in S_Fld_Haz_Ar table in the DFIRM database. If a narrow SFHA or 0.2-percent-annual-chance flood zone is shown on the FIRM, then a narrow polygon must be included in the DFIRM database. If the width of this flood insurance risk zone is accurately known and represented in the spatial data, the normal flood insurance risk zone is applied. If the width of the flood insurance risk zone is not accurately known and represented because of scale limitations, then the zone is designated as 1-percent-annual-chance flood contained in channel or 0.2-percent-annual-chance flood contained in channel as appropriate.

This is the flood insurance risk zone designation. These zones are used by the Federal Emergency Management Agency (FEMA) to designate Special Flood Hazard Areas (SFHAs) and for insurance rating purposes. Some older FEMA FIRMs were prepared in the Standard format that uses Zones B, C and numbered A and V zones. Newer FIRMs use the Map Initiatives format where the B corresponds to 0.2 pct ANNUAL CHANCE FLOOD HAZARD; C corresponds to Zone X; numbered A zones (e.g., A1, A2, A3) correspond to Zone AE; and numbered V zones (e.g., V1, V2, V3) correspond to Zone VE. All Digital Flood Insurance Rate Maps (DFIRMs) should use the Map Initiatives zone designations. See Volume 1, Subsection 1.4.6.1.5 of these Guidelines for details on the flood insurance risk zones. (NOTE: The symbol '%' is a reserved symbol in most software packages so the word 'percent' was abbreviated to 'pct'.)

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. 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 the individual FIRM Database components of the NFHL 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 reports that accompany the individual FIRM Database components of the NFHL. Users should be aware that BFEs shown in the S_BFE table may 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. 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. 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.

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. The reliability of the floodplain boundary delineation is quantified by 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.

However, no methodology was performed by GeoPlan to correct for these issues. For more information on FEMA's Final Data Structure concerning sliver polygons please see below. The FEMA report frm_gsal.pdf states the following regarding sliver polygons. L.3.5.2 Topology Vector data files must meet the following data structure requirements: * Area spatial features for a given theme must cover the entire study area without overlaps, underlaps or sliver polygons between adjacent polygons. Next Deleted the following 3 features due to spatial errors: 12123C_10583 (Duplicate Polygon), 12111C_1676 (Zero Area), 12097C_502 (Negative Area). It was noted that 45 features had vertex counts greater than 500,000. Features with large vertex counts are known to cause database analysis crashes and errors. The ArcGIS Dice Tool subdivides a feature into smaller features based on a specified vertex limit. This tool is intended as a way to subdivide extremely large features that cause issues with drawing, analysis, editing, and/or performance but are difficult to split up with standard editing and geoprocessing tools. This tool should not be used in any cases other than those where tools are failing to complete successfully due to the size of features.
