SB 429 establishes the Wildfire Safety and Risk Mitigation Program to fund one or more universities to develop, demonstrate, and deploy a public wildfire catastrophe model and related outreach. The statute defines a public model as one with accessible documentation, data, and algorithms and authorizes grants for both model development and user education.
The bill focuses the program on practical use: informing emergency planning, supporting mitigation actions at property and community scales, improving actuarial and insurance oversight, and training students and professionals. It creates a dedicated account in the Insurance Fund, requires the insurance department to run a competitive grant process with specific standards, and mandates publication of a multiyear framework, milestones, and budget recommendations to the Legislature and Governor.
At a Glance
What It Does
The state insurance department must administer competitive grants to universities for building an openly documented wildfire catastrophe model and outreach programs, publish a multiyear development framework online, and place funds in a new Wildfire Safety and Risk Mitigation Account inside the Insurance Fund. The department must also identify milestones for model completion and submit budget recommendations by September 1, 2026.
Who It Affects
Public higher education institutions and university research centers that pursue grant funding; the California Department of Insurance (the administering department) and its staff; state and local emergency planners, insurers, actuaries, and communities—especially disadvantaged and vulnerable communities prioritized in grant evaluations.
Why It Matters
Most catastrophe models are proprietary; this bill directs public investment to produce an open, documented model that regulators, planners, and communities can use directly. That shift could change how risk is assessed for mitigation planning and insurance oversight, while creating a pipeline of trained students and reproducible modeling tools for public use.

What This Bill Actually Does
SB 429 creates a grant program intended to produce a public wildfire catastrophe model — a computer process that simulates property damage from large wildfires and, crucially, includes accessible documentation, underlying data, and algorithms. The statute limits grant recipients to one or more universities and explicitly authorizes grants both for building the model and for outreach to equip potential users, such as emergency planners and educators.
The California Department of Insurance (referred to in the bill as “the department”) runs the program. The department must run a competitive grant process and set minimum standards, funding schedules, performance criteria, and metrics.
When setting those standards it must ensure alignment with specified insurance regulations, consider modeling and actuarial research that tests mitigation effectiveness across property, community, and utility scales, and require public-facing outputs useful for property- and community-level mitigation planning.Grant evaluation prioritizes proposals that benefit disadvantaged or otherwise vulnerable communities, help state and local governments protect and recover from wildfire disasters, provide educational experiences across public higher education institutions, and make model outputs and scenario tools available for governments and others to run loss-reduction scenarios. The department is instructed to maximize leverage of federal and private funds and to ensure program activities complement federal and private industry efforts, including insurance market practices.Operationally, the bill requires publication of a multiyear development and deployment framework on the department’s website, creation of a dedicated Wildfire Safety and Risk Mitigation Account within the Insurance Fund to hold program funds, and the posting of key milestones once the first round of grants is implemented.
The department must also deliver budget recommendations to relevant legislative committees and the Governor by September 1, 2026. The statute clarifies that nothing in the article limits the insurance commissioner’s authority over rate regulation or other code provisions, and the program becomes operative only upon appropriation.
The Five Things You Need to Know
The bill defines a “public wildfire catastrophe model” to require readily accessible documentation and programs, explicitly including underlying data and algorithms for public use.
The department must consider and align program standards with specific Title 10 California Code of Regulations provisions cited in the bill when setting grant criteria and metrics.
SB 429 creates a Wildfire Safety and Risk Mitigation Account inside the Insurance Fund to hold and disburse program funds.
Grant evaluation gives priority to projects that demonstrate concrete benefits to disadvantaged and vulnerable communities and that address areas where insurance access has become a major challenge because of wildfire risk.
The department must publish a multiyear framework and key milestones online and submit recommendations for future budget allocations to legislative insurance and emergency management committees and the Governor by September 1, 2026.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Establishes the program, eligible projects, and public-model definition
Section 970 creates the Wildfire Safety and Risk Mitigation Program, authorizes grants to one or more universities, and limits eligible projects to either (1) developing a public wildfire catastrophe model with public-facing documentation and data, or (2) outreach to educate potential users. It spells out the functional purpose: improving emergency planning, mitigation research, actuarial work, training, and insurance oversight. The statutory definition of “public model” is operational: the model must make its methods and datasets readily available for use by public agencies and others.
Administration, grant process, and standards to guide awards
This section assigns administration to the department and requires a competitive award process with minimum standards, funding schedules, and procedures. It lists eight specific considerations the department must weigh—performance metrics, consistency with cited insurance regulations, R&D on mitigation effectiveness, promotion of publicly accessible mitigation information, leveraging federal/private funds, complementing federal/private efforts, alignment with local/state hazard mitigation priorities, and consideration of recommendations from a strategy group. Practically, that instructs the department to build technical, policy, and legal guardrails into solicitations and award agreements.
Priority criteria for evaluating proposals
Section 972 gives the department a transparent set of priorities for evaluating proposals: benefit to disadvantaged and vulnerable communities; assistance to governments for protection and equitable recovery; educational value across public higher education collaboration; availability of scenario-running tools for governments; property-level outputs useful for mitigation planning; inclusion of environmental risk drivers like extreme heat and drought; and improvements to consumer information and modeling transparency. These priorities will shape scoring, deliverable requirements, and expected public outputs.
Planning, account creation, milestones, and budget recommendations
Section 973 requires the department to create and publish a framework and a multiyear plan that uses available data to guide model development, demonstration, and deployment. Section 974 creates the dedicated account in the Insurance Fund to pay for the program. Section 975 instructs the department to publish key milestones after the first grant round, and Section 976 requires the department to make recommendations to specific legislative committees and the Governor on future budget allocations by a set date (September 1, 2026). Together these clauses force early public transparency about schedule, funding, and the program’s path to operational capability.
Nonpreemption of commissioner authority and appropriation condition
Section 977 affirms that the article does not limit the insurance commissioner’s authority over rate regulation or other code provisions, preserving existing regulatory powers. Section 978 conditions the program’s operation on legislative appropriation; the statute creates processes and obligations but only becomes active if and when the Legislature funds it. That affects timelines and the department’s ability to commit resources.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- State and local emergency planners — they gain access to an open model and scenario tools to run localized risk assessments and mitigation scenarios, which can improve evacuation planning and resource allocation.
- Universities and public research centers — they receive grant funding to advance wildfire modeling research, create educational programs, and train a workforce in modeling and actuarial techniques.
- Disadvantaged and vulnerable communities — the grant priority language and public availability of property- and community-level outputs aim to improve mitigation planning and potentially restore or improve access to insurance in high-risk areas.
- Insurance regulators and actuaries — an open, documented model provides a reproducible basis for oversight, solvency analysis, and rate review, reducing dependence on proprietary black-box models.
- Local governments and mitigation planners — publicly accessible, property-level information supports targeted investments in vegetation management, defensible space, and community-scale mitigation that align with hazard mitigation plans.
Who Bears the Cost
- Department of Insurance (the administering department) — must staff and run a competitive grant program, develop standards, publish frameworks and milestones, and prepare budget recommendations, with associated administrative burden and possible need for additional appropriation.
- Universities and grantees — must meet performance metrics, make data and algorithms public (which can require extra data-cleaning, documentation, and legal work), and may forego proprietary claims on model outputs.
- Private catastrophe model vendors and some insurers — face competitive pressure and potential disclosure of methods if regulators or markets shift toward the public model; they may need to respond by differentiating services or changing commercial strategies.
- California Legislature/Treasury — must appropriate funds to activate the program and may face requests for follow-on funding based on the department’s recommendations.
- Local governments and property owners — while they benefit from model outputs, implementing mitigation actions identified by the model will often require local spending and resources that those entities must find.
Key Issues
The Core Tension
The central tension is between public transparency and practical utility: making a catastrophe model openly available promotes public trust, equitable planning, and regulator access, but publicizing data and algorithms can undermine private investment in modeling and force trade-offs between reproducibility and models’ commercial complexity — with real implications for insurance markets and mitigation financing.
The bill pushes for public transparency in catastrophe modeling while leaving several implementation challenges unresolved. First, data quality and coverage vary widely across parcels and regions; producing property-level outputs that are both useful and defensible for planners and insurers will require significant data curation, harmonization, and ongoing updates.
Second, the open-data requirement creates intellectual property and commercial tensions: universities that collaborate with private partners may need to negotiate access to proprietary inputs or accept the burden of replacing those inputs with public alternatives.
A second cluster of trade-offs involves regulatory and market impacts. An openly published model can improve regulator visibility into insurer assumptions, but if regulators or markets rely on the public model without clear statutory authority to do so, insurers could challenge decisions grounded in a model that differs from industry-standard proprietary approaches.
Funding and timing also matter: the program is operative only upon appropriation and the department must deliver recommendations by a fixed date, but the statute does not appropriate funds or specify continuation funding, leaving the program potentially episodic rather than sustained.
