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. These digital data are produced for the purposes of updating/creating a FIRM Database.\r\n \r\n \r\n \r\n \r\n 20250520\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 -115.000\r\n -113.962\r\n 43.840\r\n 42.822\r\n \r\n \r\n \r\n \r\n ISO 19115 Topic Category\r\n hydrology\r\n environment\r\n inlandWaters\r\n \r\n \r\n FEMA NFIP Topic Category\r\n Floodplain Mapping\r\n Redelineation\r\n Flood Insurance Rate Map\r\n FIRM\r\n FEMA Flood Hazard Zone\r\n FIRM Database\r\n Special Flood Hazard Area\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 Floodway\r\n \r\n \r\n None\r\n REGION 10\r\n STATE ID\r\n COUNTY BLAINE\r\n COUNTY-FIPS 013\r\n\t\tCOMMUNITY City of Bellevue\r\n\t\tFEMA-CID 160021\t\r\n\t\tCOMMUNITY City of Hailey\r\n\t\tFEMA-CID 160022\t\r\n\t\tCOMMUNITY City of Ketchum\r\n\t\tFEMA-CID 160023\r\n\t\tCOMMUNITY City of Sun Valley\r\n\t\tFEMA-CID 160024\t\r\n\t\tCOMMUNITY City of Carey\r\n\t\tFEMA-CID 160234\t\t\r\n COMMUNITY Blaine County Unincorporated Areas\r\n\t\tFEMA-CID 165167\r\n HYDROLOGIC UNIT 17040219\r\n \r\n \r\n None\r\n Acknowledgement of FEMA would be appreciated in products derived from these data. These digital data are produced for the purposes of updating/creating a FIRM Database.\r\n Original data development environment may vary. Finishing of the data is done using Esri's ArcGIS software.\r\n\r\n \r\n \r\n \r\n The FIRM Database 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. Attribute accuracy was tested by manual comparison of source graphics with hardcopy plots and a symbolized display on an interactive computer graphic system. \r\nIndependent quality control testing of the FIRM Database was also performed.\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 may represent 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. 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.\r\n \r\n \r\n The FIRM Database consists of vector files and associated attributes produced in conjunction with the hardcopy FEMA FIRM.

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.
