If your community was threatened by a wildfire, would you be able to quickly evacuate? A new study from the UC Santa Barbara reveals that the number of roads out of a community may be one of the strongest predictors of wildfire fatalities, and that a surprisingly specific threshold separates high-risk communities from safer ones.<\/p>\n

Publishing in\u00a0Proceedings of the National Academy of Sciences<\/a>, researchers at UCSB\u2019s\u00a0National Center for Ecological Analysis and Synthesis (NCEAS)<\/a>\u00a0and Bren School of Environmental Science & Management\u00a0compiled the most extensive georeferenced wildfire fatality dataset to date, covering 342 deaths across the United States from 2008 to 2024. They found that fatalities drop sharply as communities gain more outward road access, but only up to about six exits. Beyond that point, additional roads offer little further protection.<\/p>\n

\u201cThe threshold near six exits held remarkably consistent across geographies and communities of different sizes,\u201d said lead author and NCEAS researcher Caitlin Fong. \u201cThat tells us it\u2019s a structural constraint, not a demographic one. Road redundancy is what saves lives.\u201d<\/p>\n

The pattern is visible in some of the country\u2019s most devastating fires. In the 2018 Camp Fire, 66 of 86 total fatalities occurred in Paradise, California \u2014 a town with six outward roads that offered limited functional redundancy as fire and gridlock converged. In 2023, 102 people died in Lahaina, Hawai\u2019i, a town with just four exit routes. In Berry Creek, California, 13 people were killed during the 2020 North Complex Fire; the community had only two exits.<\/p>\n

To assess the scale of the problem nationally, the research team combined egress data for every U.S. community under 50,000 residents with wildfire hazard maps and census population counts. Their findings are striking:<\/p>\n

\u25cf\u00a0 \u00a0 \u00a0\u00a017.7 million people\u00a0live in communities below the critical six-exit threshold<\/p>\n

\u25cf\u00a0 \u00a0 \u00a0\u00a02.5 million of those people\u00a0live in communities that also face high wildfire hazard<\/p>\n

\u25cf\u00a0 \u00a0 \u00a0\u00a0528 communities\u00a0have no major road exits at all \u2014 spread across 41 states<\/p>\n

\u25cf\u00a0 \u00a0 \u00a0\u00a0High-risk hotspots exist not only in the West, but also in\u00a0Oklahoma, Florida, and Hawai\u2019i\u00a0\u2014 states not typically central to national wildfire policy<\/p>\n

\u201cSeventeen million Americans are living in communities that, by this measure, are not designed to survive a fast-moving wildfire,\u201d said co-author Max A. Moritz, UC Cooperative Extension Wildfire Specialist for the state of California. \u201cThat should be a wake-up call \u2014 not just for California, but for every state that thinks wildfire isn\u2019t their problem yet.\u201d<\/p>\n

The researchers emphasize that road-building alone is not a complete solution \u2014 steep terrain, ecological constraints and cost make new roads impractical in many places. They point instead to three complementary approaches: expanding egress infrastructure where feasible, improving early warning systems and evacuation behavior, and investing in pre-planned shelter-in-place options like Temporary Refuge Areas for when evacuation fails.<\/p>\n

The team\u2019s risk maps, covering all small U.S. communities, are publicly available and designed to help planners, emergency managers, and policymakers prioritize where to act first.<\/p>\n

\u201cPeople think of wildfire as a Western problem,\u201d said co-author\u00a0Benjamin Halpern<\/a>, director of NCEAS. \u201cBut we found communities with dangerous combinations of limited roads and high fire risk in places that don\u2019t get a lot of attention. And as climate change expands fire hazard, that gap is only going to grow.\u201d<\/p>\n

This research is part of the\u00a0Wildfire Resilience Index, a project dedicated to building data-driven tools to help communities understand and build wildfire resilience.\u00a0An\u00a0interactive map of community egress and wildfire hazard across the United States<\/a>\u00a0is available.\u00a0Learn more at\u00a0wildfireindex.org<\/a>.<\/p>\n
