FEMA Flood Hazard Areas

FEMA Flood Hazard Areas 54347 EGH_Public STAND-ALONE FLOOD_HAZARD_FEMA Hazard 50012 The FEMA Flood Hazard Layer represents the location and attributes of flood insurance risk zones from the Flood Insurance Rate Map (FIRM) databases published by the Federal Emergency Management Agency (FEMA), and any Letters of Map Revision (LOMRs) that have been issued against those databases since their publication date. It is updated on a monthly basis. The FIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper FIRMs. The FIRM Database depicts flood risk information and supporting data used to develop the risk data. 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 floodway, 100-year floodplain/SFHA (Special Flood Hazard Area), and the 500-year floodplain are all derived from this dataset. 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. 2021-04-26 16:52:00.0 7506639.792979 7785126.39041994 768180.13615486 583686.269685045 Regional (Oregon Counties only) flood hazard, floodplain, fema, special flood hazard area, SFHA, floodway, 100-year floodplain, 500-year floodplain Available for Public Use These data are sold under the agreement that the user may use the data in its business activity and for no other purpose whatsoever.

For a single jurisdiction flood risk project, the value is composed of the two-digit State FIPS code and the four-digit FEMA CID code (e.g., 480001). For a countywide flood risk project, the value is composed of the two-digit State FIPS code, the three-digit county FIPS code, and the letter “C” (e.g., 48107C). Within each FIRM Database, the DFIRM_ID value will be identical. 6 String 50099 2016-06-20 10:24:00.0 4062 2016-08-04 10:23:00.0 3 1 0 1 319514 DFIRM_ID String 6 0 0 VERSION_ID VERSION_ID Version Identifier.
