Developers, public agencies, and other project sponsors subject to California Environmental Quality Act (CEQA) vehicle miles traveled (VMT) analysis have a new option for mitigating significant transportation impacts. The Governor’s Office of Land Use and Climate Innovation (LCI) has released the final version of the Statewide Vehicle Miles Traveled Mitigation Program Guidance (Guidance) implementing Assembly Bill 130 (2025), which created a new statewide mitigation program that allows eligible projects to satisfy VMT mitigation requirements by contributing to a state-administered fund rather than relying solely on project-specific measures.

It is intended to advance California’s broader goal of reducing emissions by directing mitigation funding to affordable housing in transit-oriented communities, where new development can generate measurable VMT reductions.

For projects where on-site or local VMT mitigation is difficult, costly, or impractical, the new program may provide a more predictable path to CEQA compliance. While the initial phase of this new statewide program is limited to public works projects, we anticipate that it will be expanded over time to also include privately funded development projects.

How It Works

The mitigation program is premised on the concept that building affordable housing reduces VMT, especially when affordable units are located in accessible, mixed-use neighborhoods. Thus, instead of designing and implementing on-site VMT reduction strategies, applicants may now elect to pay into the California Department of Housing and Community Development’s (HCD) Transit-Oriented Development Implementation Fund (TDIF), which is used to support the development of affordable housing. (See Health and Safety Code § 53561.)

Key features include:

• Contribution-based mitigation. The required payment is calculated using a regional per-mile cost formula: the number of VMT to be mitigated multiplied by the applicable regional VMT Mitigation Credit value. A VMT Mitigation Credit represents the cost to reduce one mile of travel within the relevant program region via the development of qualifying mitigating projects.
• Statewide pooling. HCD pools contributions and invests them in affordable housing projects located in transit-accessible, VMT-efficient areas which can generate real, trackable VMT reductions.
• Geographic nexus requirements. Funds are prioritized for investment within the same region as the contributing project, then in adjacent regions within a defined proximity radius, ensuring legal nexus and rough proportionality.
• Built-in CEQA compliance. The program is designed to satisfy CEQA’s enforceability, monitoring, and nexus requirements. To ensure lasting VMT reductions, mitigating affordable housing projects must carry deed restrictions that legally bind the units to income-eligible buyers for a period of 55 years.
• Anti-double-counting protections. Credits are tracked and retired through a centralized, auditable system.

AB 130 does not restrict the mitigation program to certain types of projects. Any CEQA project with a significant VMT impact is potentially eligible to participate in the mitigation program. However, to allow HCD to effectively manage program demand without overwhelming its current administrative capacity, the initial phase focuses on publicly funded projects.

What It Means for Your Projects

This program is a significant development for any project subject to CEQA VMT analysis, particularly:

• Projects in areas where on-site or nearby VMT reduction strategies are limited or cost-prohibitive;
• Infill, mixed-use, and residential developments facing significant VMT impact findings;
• Publicly funded projects, especially in the initial program phase; and
• Projects in regions where regional VMT Credits offer greater cost certainty compared to bespoke mitigation measures.

The program is voluntary. It supplements rather than replaces existing mitigation options, giving applicants flexibility to use it alone or in combination with other strategies.

What to Watch

• Rulemaking is coming. LCI is expected to commence formal rulemaking to codify the Guidance as binding regulation, with the process to begin no later than January 1, 2028. In the interim, the current Guidance governs.
• Credit values may change. Regional VMT Mitigation Credit values are publicly posted and may be adjusted annually for inflation, so timing of contributions can affect costs.
• Program scope may expand. The initial phase focuses on publicly funded projects, but the program is broadly available, and HCD’s administrative capacity is expected to grow over time.
