California’s outdated utility fire maps, last updated eight years ago, have become a focal point of concern as the state grapples with the aftermath of devastating wildfires in Los Angeles County. Despite pressure from the California Public Advocate and support from utility companies to update these maps, state regulators have declined the request, raising questions about the adequacy of current fire threat assessments.
The urgency for updated maps is underscored by the recent release of new color-coded hazard maps by California’s Department of Forestry and Fire Protection, known as Cal Fire. These maps, which were completed in March 2025, highlight a significant expansion of high-risk fire zones across the state. According to CalMatters, areas deemed “high” or “very high” hazard have increased by 168% since 2011, now covering 3,626 square miles and affecting approximately 3.7 million residents. These maps are crucial for enforcing building codes and safety measures in fire-prone areas.
The outdated utility maps, however, remain a point of contention. Utilities argue that updated maps are necessary to better manage and mitigate fire risks associated with power lines and other infrastructure. The refusal to update these maps has sparked criticism, especially in light of recent fires that have caused widespread destruction and financial strain.
The financial implications are significant, as highlighted by a Wall Street Journal report. A rule change by California’s insurance regulator now allows insurers to pass on costs to homeowners, potentially increasing insurance bills significantly. This change has raised concerns about the financial burden on residents, particularly those in areas covered by the state’s Fair Plan, an insurer of last resort.
The push for updated utility fire maps continues amid these challenges, with stakeholders emphasizing the need for accurate assessments to protect communities and manage development in California’s most fire-prone areas.
