Overview

Data on Flood Factor comes from the First Street Foundation Flood Model, and was built upon decades of peer-reviewed research and developed in partnership with more than 80 world-renowned experts.  Like all flood models, it's intended to help identify potential flood risks, and Flood Factor users are encouraged to follow up with qualified professionals and supplement this information with additional research and documentation they might have.

 

The comprehensive model integrates all major flood types, from tides, coastal surges, rains, and rivers, and uses historical flooding events to validate risk. The model also considers future environmental changes, which FEMA itself has acknowledged needs to be integrated into its flood maps.
