Why We Exist

To define your exposure

Flooding risk is vastly underestimated

40 Million People

More than 40 million Americans live in a 100-year floodplain. Yet FEMA maps only identify 13 million. Because of this, 27 million people are unaware of their exposure.

Will Flood

This group has a 1 in 4 chance of flooding during a 30 year mortgage. As sea levels rise, the risk grows and new homes fall into this flood category.

We exist to solve this problem

First Street Foundation is a registered 501(c)(3) tech non-profit that quantifies and communicates the increasing risks associated with sea level rise and flooding. We do this by conducting breakthrough research, and translating the results through digital tools that simplify and visualize.
