Yellowstone National Park flood event 2022: Road washout upriver from Rescue Creek Trailhead

Over 53 million people in the United States live in communities with high flood risks. Some of those risks are particularly pronounced in parts of our region, according to new analysis from Headwaters Economics.

Much of Idaho and a number of counties elsewhere in the West showed high or very high flood risk, according to that analysis and an interactive map produced for it. But the report notes that not all members of a community are impacted by flooding equally.

“Each type of group of person with a specific vulnerability, they might need something different to help prepare for a flood or survive the flood or recover from the flood,” said Headwaters researcher Kristin Smith. “So understanding the detail of who's at risk can be really important.”

The map allows users to look at local poverty levels, the percentage of residents in rental housing and other key demographic data. It’s intended to help officials identify places that may need more assistance or investment to get ready for floods and protect residents.

The report recommends prioritizing help in so-called lower-capacity communities, which have less staff and resources to address flooding and other risks. It also calls for putting a greater focus on people and their well-being, rather than property losses.

“Many disaster policies are focused on property values, damage assessments, and repair costs,” the report says. “As a result, high-income places often receive more attention and resources.”

Smith added, “When a flood hits a community, disasters tend to just exacerbate that inequality within the community. It speaks to the need to get ahead of the problem and to invest in solutions now so that a community doesn't have to go through these harrowing problems with terrible rippling effects for everyone.”
