The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, 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 the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the UTM projection and coordinate system.The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000. 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.

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.

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. Logical_Consistency_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. 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.

Publisher: Federal Emergency Management Agency Other_Citation_Details: 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: McDowell County, (Unincorporated Areas), the hydrologic and hydraulic analyses from the FIS report dated September 18, 1986, were prepared by the Huntington District of the U.S. Army Corps of Engineers (USACE) for the Federal Emergency Management Agency (FEMA), under Inter-Agency Agreement No. IAA-H-9-79, Project Order No. 42. That work was completed in April 1984.For this countywide FIS, new hydrologic and hydraulic analyses were performed for portions of Clear Fork and Wolfpen Branch. In addition, the effective hydrologic analyses for McDowell County were validated and effective hydraulic analyses were used to redelineated floodplains based on more detailed and up-to-date topographic information. Planimetric base map information is provided in digital format for all FIRM panels. These files were compiled at a scale of 1:12,000 from photography dated 1996 or later. The coordinate system used for the production of this FIRM is Universal Transverse Mercator (UTM) Zone 17, North American Datum of 1983 (NAD 83), GRS 80 spheroid. This FIS covers the geographic area of McDowell County, West Virginia and incorporated areas.For this revision, the following streams are newly studied by limited detailed methods (only the 100-year water surface elevation has been computed). Clear Fork from a point approximately 7.2 miles upstream of its confluence with Tug Fork to the confluence of Wolfpen Branch. Wolfpen Branch from its confluence with Clear Fork to approximately 0.8 mile upstream of its confluence with Clear Fork. This work was performed by AMEC Earth & Environmental, Inc. This FIS also incorporates the floodways that were computed using the limited detailed HEC-RAS hydraulic models developed by AMEC Earth & Environmental, Inc for Clear Fork and Wolfpen Branch. These floodways were modeled using the equal conveyance reduction method and mapped using the floodway delineation tool developed by Dewberry. A Letter of Map Revision effective on April 16, 2003 was incorporated, which revised the 100- and 500-year floodplains and floodway for approximately 4,200 feet along Dry Fork in the unincorporated areas of McDowell County. In addition, the effective hydrologic analyses have been validated and the 100- and 500-year floodplains have been redelineated for each stream previously studied in detail based on more detailed and up-to-date topographic information. Approximate flood hazard areas have also been revised based on the aforementioned topographic data. 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. The following streams have been studied by detailed methods: Bottom Creek, from its confluence with Elkhorn Creek to a point approximately 130 feet upstream of Bottom Creek Road. Browns Creek, from its confluence with Tug Fork to a point approximately 950 feet upstream of the upstream corporate limits of the City of Welch. Davy Branch, from its confluence with Tug Fork to a point approximately 1.5 miles upstream of the upstream corporate limits of the Town of Davy. Dry Fork, from its confluence with Tug Fork to a point approximately 260 feet upstream of the confluence of Big Branch. Elkhorn Creek, from its confluence with Tug Fork to a point approximately 790 feet upstream of Norfolk Road. Little Creek, from its confluence with Tug Fork to point approximately 1,870 feet upstream. Puncheoncamp Branch, from its confluence with Browns Creek to a point approximately 1,000 feet upstream. Sandlick Creek, from its confluence with Tug Fork to a point approximately 1,630 feet upstream of the Norfolk Southern Railway. Tug Fork, from the downstream county boundary to a point approximately 2,000 feet upstream of the upstream corporate limits of the Town of Anawalt. War Creek, from its confluence with Dry Fork to a point approximately 1.5 miles upstream. Numerous streams 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 McDowell County.
