CA SBX110

Shifts control of 75% of regional transportation improvement funding from the California Transportation Commission to local transportation agencies (metropolitan planning organizations, transportation planning agencies, and county transportation commissions) by establishing block grant apportionments based on population (75%) and state highway miles (25%).

Requires the Department of Transportation to annually apportion regional improvement funds directly to local agencies, which then identify projects in their regional transportation improvement programs rather than having the Commission select projects.

Eliminates the Commission's role in programming and allocating regional transportation funds but retains oversight authority to reject entire regional programs if they are inconsistent with guidelines or not cost-effective, requiring objective analysis and public hearings.

Changes the state transportation improvement program from a document allocating specific projects to a compilation document that incorporates regional programs submitted by local agencies without individual project-level commission approval.

Repeals provisions related to county share computation over multiple years and eliminates detailed fund-balancing requirements that previously tracked county surpluses, shortfalls, and reservations across four-year periods.
