California Inspector General Finds High-Speed Rail Business Plan Lacking Key Details

On November 8, 2026, the California Office of the Inspector General (OIG) released a review of the California High‑Speed Rail Authority’s (CHSRA) final 2026 Business Plan. The report finds that, while the plan is more complete than the draft, it still falls short of several legal and transparency requirements, raising questions about cost estimates, schedule timing, and the funding status of the Merced‑to‑Bakersfield segment.

The OIG’s review was mandated by the California Public Utilities Commission (CPUC). In April, the CPUC examined a draft version and labeled it “objectively incomplete.” It notified the CHSRA Board of Directors and urged staff to fill in missing information. The Board complied, incorporating additional data into the final plan, which the OIG now calls a “meaningful improvement.”

However, the review notes that the plan still omits the funding‑plan information required by a recently enacted state law.

Key concerns center on the 171‑mile Merced‑to‑Bakersfield stretch, a component of the Initial Operating Segment (IOS) of Phase 1. The plan does not clearly explain the changes in scope and cost between earlier estimates and the current figures, a gap that violates legal requirements for comparable cost estimates.

The reduced‑scope estimate excludes several significant potential costs: financing costs estimated at $3.6 billion to $6.6 billion; a $1.2 billion difference tied to a default‑level contingency budget; $816 million in construction costs that the Authority assumes other entities will pay; and $1.7 billion related to infrastructure required under an existing local agreement that the Authority expects to modify.

The OIG also points out that the plan includes a full‑scope estimate for the same segment, but places it in a risk‑management section rather than the cost section. The Authority does not explain that the higher estimate contains additional cost assumptions not required by state law, which could mislead readers about the true cost of compliance.

Schedule issues also receive scrutiny. The plan acknowledges a nine‑month slip in the Merced‑to‑Bakersfield schedule between August 2025 and March 2026 but fails to explain the “optimization and pending policy changes” cited as causes. It also does not disclose that the schedule window for the segment is no longer 2032‑2033; the Authority’s risk‑based statistical analysis now indicates the appropriate window extends to September 2034.

Funding urgency is under‑stated. The OIG says the plan does not sufficiently emphasize that the Authority could exhaust its current funding resources as early as December 2027 if new financing is not secured.

Transparency problems extend beyond the business plan. The OIG notes that the Authority’s recent annual reports have been incomplete and late, preventing decision‑makers and the public from fully reviewing key information. For example, stakeholders had only a few days to comment on new information added to the final plan before the Board adopted it.

The OIG has previously made recommendations to improve transparency in the Authority’s annual reporting. Most of those recommendations have not been fully implemented. The agency says basic facts about the project have sometimes remained unclear or obscured, complicating legislative oversight and potentially hindering the Authority’s ability to secure stakeholder agreements or legislative action.

In response, the OIG is directing the Board to adopt and enforce a policy governing annual reports. The policy would set timelines for preparing and reviewing complete reports and ensure stakeholders receive a meaningful opportunity to review them before issuance.

The review concludes that, because the Authority has not yet demonstrated a consistent reporting process that guarantees accuracy and transparency, the OIG’s recommendations are essential. The next steps will involve the Board’s adoption of the new reporting policy and the Authority’s continued effort to provide complete, comparable cost estimates, clear schedule explanations, and a transparent funding plan for the Merced‑to‑Bakersfield segment.

The OIG’s findings underscore ongoing challenges for California’s high‑speed rail project, a program that has faced cost overruns, schedule delays, and funding gaps since its inception. The Authority’s ability to address these concerns will be critical to maintaining public trust and securing the resources needed to complete the system.
