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 Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information 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).\r\n The objective of the Floodplain Mapping/Redelineation data submission is to archive the flood boundary and redelineation data for a study in a database such that it can be revised and used with minimum effort in future flood insurance studies or map revisions. This digital data is produced for the purposes of updating/creating a DFIRM database.\r\n \r\n \r\n \r\n \r\n 20080423\r\n \r\n \r\n MIP Submission Date\r\n \r\n \r\n In work\r\n Unknown\r\n \r\n \r\n \r\n -165.471209\r\n -165.369323\r\n 64.529194\r\n 64.49189\r\n \r\n \r\n \r\n \r\n FEMA NFIP Topic Category\r\n Floodplain Mapping\r\n Redelineation\r\n DFIRM\r\n FIRM\r\n FEMA Flood Hazard Zone\r\n DFIRM Database\r\n Special Flood Hazard Area\r\n Digital Flood Insurance Rate Map\r\n CBRS\r\n Coastal Barrier Resources System\r\n Riverine Flooding\r\n Coastal Flooding\r\n NFIP\r\n Base Flood Elevation\r\n SFHA\r\n Flood Insurance Rate Map\r\n Floodway\r\n \r\n \r\n ISO 19115 Topic Category\r\n hydrology\r\n environment\r\n inlandWaters\r\n structure\r\n transportation\r\n elevation\r\n \r\n \r\n None\r\n REGION 10\r\n STATE AK\r\n COUNTY NOME\r\n COUNTY-FIPS 180\r\n COMMUNITY CITY OF NOME\r\n FEMA-CID 020069\r\n \r\n \r\n None\r\n The hardcopy FIRM and DFIRM and the accompanying FISs are the official designation of SFHAs and Base Flood Elevations (BFEs) for the NFIP.

Finishing of the data is done using ESRIs ARC/INFO software.\r\n \r\n \r\n \r\n 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.\r\n Independent quality control testing of FEMA's DFIRM database was also performed.\r\n 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.\r\n \r\n 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.\r\n Data contained in the Floodplain Mapping and Redelineation 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.\r\n 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.\r\n \r\n \r\n The DFIRM Database consists of countywide vector files and associated attributes produced in conjunction with the hardcopy FEMA FIRM. The published effective FIRM and DFIRM 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.
