During the Camp Fire, the average age of those who died in Butte County was 72. Because of this and other disasters, the state says taking care of vulnerable people is a priority.

We mapped the state’s moderate, high and very high risk fire zones.

Cal Fire used vegetation, fire history and topography to create these maps. They’re being updated to better account for risk.

So, we added scientific maps that show where sprawl and building increase risk: in the wildland-urban interface where development is near open lands, and the intermix where houses and wildlands commingle. Rural areas also burn: some are mainly vegetation, and others are sparsely inhabited.

Combined, these zones show how fire is a daunting hazard across much of California.

There are more than 10,000 long-term care facilities in California, from six-bed assisted living homes to large nursing centers.

Our analysis found that 35% of these facilities are in risky areas. With as many as 105,000 residents to safeguard if fire comes, these care home operators must now consider how to evacuate during a pandemic, a more complicated and difficult task.

Since new federal emergency preparedness rules took effect in 2017, regulators have caught most of the nursing homes in the state violating them, according to public records.

Most Californians 65 and older don’t live in care homes though, and are especially vulnerable to fires physically, mentally, economically and socially.

In 23 counties, older Californians overwhelmingly choose to live in fire-prone areas. Including in San Luis Obispo County, where 82% do.

That means nearly 2 million older Californians live in the red areas where wildfire is a formidable threat. Read the series.
