Nearly 20,000 communities across the United States and its territories participate in the National Flood Insurance Program (NFIP) by adopting and enforcing floodplain management ordinances to reduce future flood damage. Managed by the Federal Emergency Management Agency (FEMA), the NFIP makes Federally backed flood insurance available to homeowners, renters, and business owners in these participating communities. Using geospatial tax parcel data, flood insurance policies and claims can be more accurately geocoded to individual properties (addresses) to determine the proximity to current and future flood hazards. Enhanced attribute matching on these maps—including address, year built, number of stories, square footage, assessed value of property and land, etc.—will greatly increase the accuracy of risk and loss reports and be used to mitigate risk through floodplain management and building codes.
