How new flood risk maps could undermine marginalized neighborhoods

Floods are among the most destructive and expensive climate-related disasters in the US. Not just for cities and states, but for individual homeowners.

More homes are at risk of severe flooding than we used to think. On June 29, the New York-based nonprofit research outfit First Street Foundation published a remarkable set of updated flood maps for the continental US, revealing that official flood maps leave out huge swaths of the country—both on the coast and alongside inland rivers—that are, in fact, at high risk.
