The Insurance Information Institute (Triple-I)'s recent study shared insights into how geospatial property-level data analysis can help insurers more accurately identify insurable properties in wildfire-prone areas of California previously deemed too high-risk.

The report, "Getting Granular to Find Lower-Risk Properties Amid Wildfire Perils," shares analysis of Guidewire HazardHub predictive Wildfire Score data and examines zip codes in Los Angeles, Mendocino and El Dorado, all three of which were identified by the California Department of Insurance (CI) as "undermarketed" by insurers according to the press release. Triple-I's analysis shows strong fire-suppression success rates of 90% in areas of Los Angeles, 95% in Mendocino and 97% in El Dorado. 

"The traditional approach to wildfire risk assessment has left many Californians without access to affordable property insurance coverage," said Dale Porfilio, Triple-I chief insurance officer, in a statement. "Our research shows that with more detailed, property-level analysis, insurers can confidently offer coverage in areas previously deemed too risky."

The study demonstrates that granular risk assessment shares traditional assessment variables like density and slope, as well as more specific details on factors such as vegetation, drought conditions and fire-suppression success rates.

The Triple-I study also discusses that as there are fewer price insurance options available in the state, more Californians are turning to the California FAIR plan, which offers less coverage at a higher premium. This is not a sustainable long-term solution, according to the report, and Triple-I emphasizes the opportunity for reliable high-quality data to more accurately assess risk at the property level.

"To sustainably write insurance in California and other wildfire-prone states, insurers need access to granular property-level data, modern wildfire risk models and a regulatory environment that embraces innovation," said Leo Tenenblat, senior vice president and general manager of data and analytics at Guidewire, in a statement. "The Triple-I analysis highlights how next-generation tools and data can uncover lower-risk properties – even in high-risk areas – empowering insurers to expand coverage confidently and responsibly."
