CAL FIRE releases updated fire hazard severity tone map for public comment, will host 57 public hearing throughout California

16 December 2022

USA – After years of planning and collaboration with fire scientists, firefighters, stakeholders, and local
community partners, the new map reflects changes in fire hazard in unincorporated, rural areas, as experienced in California over past years.

Sacramento – CAL FIRE – Office of the State Fire Marshal this week will begin a public comment
period for the regulatory adoption process to update the existing map that captures Fire Hazard
Severity Zones (FHSZ), which is a comprehensive map that ranks California’s State Responsibility
Area (SRA)—or rural, unincorporated areas—based on the likelihood different areas will experience
wildfire.

After years of work to develop a sound scientific basis and methodology with a range of experts and
stakeholders, updates to this map bring this valuable tool and statutory requirement current in a way
that accurately reflects today’s reality for wildfire hazard throughout the state. More specifically, this
process includes a few details to know below:
• This current revision only updates areas in California’s unincorporated, rural areas
where wildfires tend to be frequent—called the “SRA” or “State Responsibility Area.” This
does not include cities or large urban areas.
• This process does not change rules or requirements for homes or properties in these areas
related to wildfire prevention, preparedness, and mitigation. The same requirements will remain
regardless of whether a particular area is reclassified or not.
• The last Wildfire Hazard Severity Zone map was updated in 2007 and required an
update. A lot has happened since 2007. Using the best available science with academic
researchers and others, this updated map reflects the impacts of a changing climate and
includes a variety of other key factors.
• This is the beginning of a nearly two-month public process. These maps are being shared for
your comments and questions during the regulatory process. A total of 57 public hearings will
be held throughout the state with the goal of hearing from you.
• An online public toolkit and interactive map is available to help answer your questions.
Take some time to explore your address, read the FAQs, learn about the process and where to
turn. A hotline is also available to help answer your questions directly and to help increase
access.

CAL FIRE NEWS RELEASE
California Department of Forestry and Fire Protection

“Ensuring Californians know the wildfire hazard in their area is critical to ensuring we all take the
appropriate steps to prepare for wildfires,” said Chief Daniel Berlant, CAL FIRE Deputy Director of
Community Wildfire Preparedness and Mitigation. “The updated map is the product of years of
discussions and incorporates the latest science to provide a long-term outlook of an area’s wildfire
hazard.”

CAL FIRE’s fire scientists and wildfire mitigation experts developed the map using a science-based
and field-tested model that assigns a hazard score based on the factors that influence fire likelihood and
fire behavior. Many factors are considered, such as fire history, existing and potential fuel (natural
vegetation), predicted flame length, blowing embers, terrain, and typical fire weather for an area. These
zones fall into the following classifications – moderate, high, and very high.

Working closely with the Department of Insurance and other agencies, CAL FIRE is creating a shared
approach to further reduce wildfire risk that assists residents and businesses with accessing affordable
insurance. The Department’s first-ever report on climate insurance recommended updated wildfire
hazard mapping to improve public safety. Insurance companies and researchers, along with insurance
agents and brokers, have been involved throughout this process to ensure cooperation between all
sectors to better support Californians. And while insurance companies use similar methodologies to
calculate risk as they price their insurance offerings to consumers, insurance risk models also
incorporate many factors beyond this process, and many of these factors can change more frequently
than those that CAL FIRE includes in its hazard mapping.

CAL FIRE remains committed to answering all questions from the public and working with the
Department of Insurance, the insurance industry, and consumer groups throughout this process.

“Making California safer from wildfires is our top priority, and my Department of Insurance will
continue to work closely with the first responders at CAL FIRE to better prepare our communities,”
said Insurance Commissioner Ricardo Lara, who issued the Safer from Wildfires insurance framework
with CAL FIRE and other agencies earlier this year as well as finalizing his new regulation to increase
access to wildfire safety discounts and to ensure consumers can learn more about wildfire risks being
considered by their insurance company. “Public education about where current wildfire hazards exist is
essential to reducing the threat to local communities and maintaining access to affordable insurance. I
encourage Californians to ask questions in this public process and to learn more about the tools that
exist to help communities and governments reduce their local risks.”

Overall, the map shows increased fire hazard, reflecting California’s increase in wildfire
occurrence and severity because of many factors, including a changing climate. The map has been
updated to more accurately reflect the zones in California that are susceptible to wildfire, to help
provide transparency for planning and preparedness efforts, and to provide communities a forecasting
tool so that the public can take steps to prevent and prepare for wildfire. The hazard mapping process
incorporates local climate data and changes in burn probability based on recent trends in fire
occurrence. The model was reviewed and validated by members of the science community, as well as
with outreach with various stakeholders including insurance, building, fire, and local agencies.

“Counties acknowledge the importance of accurately mapping fire hazard severity zones,” said Doug
Teeter, Butte County Supervisor and Incoming Chair, Rural County Representatives of California.
“RCRC member counties appreciate CAL FIRE’s continued engagement of local governments in this
important effort.”

The State Fire Marshal is mandated by California Public Resource Code 4202-4204 to classify lands
within the SRA into FHSZs and the most recent SRA FHSZ map was last updated in 2007. The FHSZ zones are used for several purposes, including to designate areas where California’s defensible space
standards, wildland-urban interface building codes, and the State Minimum Fire Safe Regulations are
required. They can be a factor in real estate disclosure, and local governments may consider them in
their general plan. However, officials stress it is important to note that within the SRA mitigation
requirements already apply to all zones. A designation change for an area does not affect the legal
requirements for mitigations since they are already required consistently across the SRA.

“As we continue to focus on addressing California’s housing crisis, we support the importance of
building so that structures are safely designed and built to mitigate an area’s wildfire hazard,” said Dan
Dunmoyer, President and CEO of the California Building Industry Association. “To build more fire
safe communities in the future, it is critically important for CAL FIRE to update these maps to ensure
we all can take steps to build a more resilient California.”

Ways to stay informed and join the conversation

As part of the adoption process of the map, CAL FIRE invites public comment on the proposed map
between December 16, 2022, and February 3, 2023. The public may submit written comment at the
address below or through email at FHSZcomments@fire.ca.gov. In addition, CAL FIRE will host a
public comment hearing in all 56 counties that have SRA to receive public comment. Information on
the hearings can be found on CAL FIRE’s website at osfm.fire.ca.gov/FHSZ.

Written comments may be submitted by U.S. mail to the following address:
Office of the State Fire Marshal
C/O: FHSZ Comments

P.O. Box 944246
Sacramento, CA 94244-2460

To determine the FHSZ of a property, the public can easily search an address using a new FHSZ
Viewer at osfm.fire.ca.gov/FHSZ.

In order to help California residents better understand the FHSZ map and answer questions, CAL FIRE
has created a public toolkit on its website to include new and easy to follow sections, including maps,
frequently asked questions, and an automated “hotline” to contact for specific information. The new
website also includes dates, times, and locations of FHSZ public hearings that will be held in the 56
Counties that have FHSZs within the SRA. For information about FHSZs, visit the program’s website
at osfm.fire.ca.gov/FHSZ. The public can also call an automated hotline at (916) 633-7655.

Following the adoption of the SRA FHSZ Map, CAL FIRE – Office of the State Fire Marshal will
begin providing local governments updated FHSZ maps for Local Responsibility Areas. Under
California Government Code 51178, the State Fire Marshal is required to provide local agencies with
the areas within their jurisdiction that meet FHSZ criteria for their local adoption and implementation.
