Flood Risk Data Available on realtor.com

Flood risk data features are now available on most for-sale properties on realtor.com®

What are these features?
At an individual property level, realtor.com® will offer insights into Federal Emergency Management Agency (FEMA)-categorized flood zones and a new Flood Factor™ feature, which is the result of a realtor.com® data integration with the First Street Foundation, a nonprofit research and technology group. The First Street Foundation Flood Model includes data for more than 142 million homes and properties across the U.S. 

Flood Factor™ includes a flood risk score ranging from 1 (minimal risk) to 10 (extreme risk) and an indication of whether that risk is increasing, decreasing, or constant over the next 30 years.  

In addition, a graph shows the cumulative risk of flooding for a property over the typical 30-year period of ownership, along with the FEMA-categorized flood zone for the property, and whether flood insurance is required. Flood insurance options, when available, are provided to realtor.com® users.

Here are some distinguishing features for both:

Flood Factor™
Provides accurate, property-level flood risk information
Incorporates current and future environmental changes
Maps multiple flood zones and risk levels
Includes more flood sources such as heavy rainfall
Nationwide coverage and updated quarterly
Assesses historic flood patterns and projects future risk

FEMA
Provides detailed, community-wide flood risk information
Maps the 100-year flood zone and indicates whether a property is “in or out” of this zone
Does not provide information specific to individual properties
Based on site specific, engineering studies but limited to two risks (riverine and storm surge)
Limited geographic coverage and not updated frequently
Assesses historic flood patterns
Used by community regulators, banks and lenders

Flood Factor™ data augments FEMA’s maps, so real estate professionals can use both tools on realtor.com® to:
Help reduce the number of clients who buy high-risk properties by surprise or list properties before mitigating the risk
Help reduce flood-related surprises at the closing table by helping their buyer and seller clients perform due diligence and increase confidence in real estate markets particularly where FEMA does not currently map

Agents and brokers can use the feature to provide additional context, guidance and insights to their buyer and seller clients with regard to flood conditions and potential flood risk for properties and communities across the country.
