Counting homes in the Western Wildland-Urban Interface ~Mitch Tobin, EcoWest

Posted on October 17, 2013 By

When firefighters are deployed to battle wildfires, they often focus on saving structures in the wildland-urban interface (WUI), where homes mix with or border flammable vegetation.

Where are these vulnerable homes located in the West?

Data from analytics firm CoreLogic provide a good high-level overview of the Western WUI. I’ve created a dashboard on this page to summarize their numbers.

CoreLogic uses four categorizes to describe the risk of wildfires destroying residential properties: very high, high, moderate, and low. There are also categories for agricultural and urban properties, which are not rated for their fire danger.

In the 13 Western states it analyzed, CoreLogic found some 740,000 residences at high or very high risk for wildfire damage and those homes are valued at more than $136 billion. Nearly 168,000 homes, valued at more than $32 billion, are in the very high risk category. Read more.

Geographic disparities: Above are a couple of views of the data (click to enlarge). The map shows the number of homes in the very high risk category, with the circles colored by the percent of homes in each state that are in this most vulnerable category. You can see that California and Colorado both have nearly 50,000 homes in this category, but while that’s about 3 percent of Colorado’s residential properties, it’s just 0.5 percent of California’s. The bar chart shows what percent of each state’s homes are in the very high and high categories.
