National Flood Insurance Program

NFIP Multiple Loss Properties

This dataset provides information on structures that have had multiple National Flood Insurance (NFIP) claims across the history of the program. The data contains NFIP-insured structures that fall within the four categories of Repetitive Loss and Severe Repetitive Loss that FEMA tracks. Definitions of these categories are provided in the field descriptions. There are also fields to show whether a structure is currently NFIP-insured, has been mitigated, and other characteristics. The data includes properties that have since been mitigated or demolished and may no longer considered to be in any of the listed categories. An online map of this data can be found on FEMA's ArcGIS Online platform: https://fema.maps.arcgis.com/apps/mapviewer/index.html?webmap=38568a4cd92b4f4ba469b1d56d772829 Location information has been redacted to protect personal privacy. Location information is derived from reported address, geocoding of that address, and reported NFIP community. Because NFIP insurance claims data spans the history of the NFIP, many of the structures have poor address information resulting in poor or missing coordinates and additional location fields that rely on those coordinates. An effort has been made to fill in missing data and resolve conflicts between state, county, community, and census block group. Because of this effort, <em>statistics derived from this data may differ from those reported elsewhere by FEMA or others</em>. There is a lot of interest in this data as it touches many program areas of the NFIP and serves as an indicator of flood risk and mitigation need. A Policyholders Guide to Severe Repetitive Loss can be found on the https://agents.floodsmart.gov/resource-library/en/policyholders-guide-severe-repetitive-loss page.
