this entity is one of the data points covered by this site’s U.S. flood risk, NFIP claims, and disaster declarations dataset. The detail above comes directly from FEMA OpenFEMA datasets including the National Flood Hazard Layer and NFIP claims; the context that follows situates the headline numbers against the broader distribution across U.S. ZIPs, counties, and states.
The methodology behind every numeric value on this page is publicly documented on the FEMA OpenFEMA datasets including the National Flood Hazard Layer and NFIP claims portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.
Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for this entity’s peers within U.S. ZIPs, counties, and states. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.
