HDR Inc. Wins Coachella Valley Rail Tier 2 Review California
HDR Inc. secured the Tier 2 review contract for California’s 144-mile Coachella Valley Rail, including nine new stations.

RIVERSIDE, USA – The Riverside County Transportation Commission (RCTC) has selected HDR Inc. to manage the next major phase of the Coachella Valley Rail project. The firm will lead the Tier 2 environmental review and conceptual engineering for the 144-mile corridor. This phase, which includes a station location study, is set to begin in 2024.
What Is the Full Scope of This Project?
The project aims to establish daily intercity passenger rail service between Los Angeles Union Station and the Coachella Valley. The scope of this phase involves developing project-level environmental clearance under both the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA). The work includes conceptual engineering to define the project footprint, a station location study for the nine proposed stations, and an update to the service development plan for federal approval.

How Does This Compare to Similar Projects?
This project represents a significant regional passenger rail investment, a trend seen in other major U.S. metropolitan areas. For comparison, Seattle’s Sound Transit is advancing a major light-rail expansion program where other large engineering firms are managing contracts for specific corridor extensions (Source: Construction Dive, 2024). While the value of HDR’s contract was not disclosed, the firm’s involvement in large-scale procurement is notable; it is concurrently active in the procurement process for a £3bn public sector construction framework in the UK’s West Midlands (Source: Construction News, 2024), indicating its capacity for managing complex, high-value infrastructure programs.
Editor’s Analysis
Advancing the Coachella Valley Rail project to the Tier 2 environmental review is a critical step in turning a long-held vision into a viable service. This project aligns with a broader infrastructure investment trend focused on creating regional mobility options beyond highways, a strategy that requires a skilled workforce to execute. The development of local infrastructure workforce roadmaps, as seen in other parts of Southern California, will be essential for the successful delivery of this and similar large-scale projects (Source: The Desert Review, 2024).
FAQ
Q: Who is the lead agency for the Coachella Valley Rail project?
A: The Riverside County Transportation Commission (RCTC) is the lead agency for this project. Although the California High-Speed Rail Authority is a key entity in statewide rail planning, RCTC is managing the development of this specific 144-mile corridor.
Q: What is a Tier 2 environmental review?
A: A Tier 2 environmental review is a project-level analysis required by the National Environmental Policy Act (NEPA). It follows a broader Tier 1 study and focuses on the specific impacts, alignments, and station locations of the proposed rail line.
Q: How will this project affect existing freight operations?
A: The plan requires significant infrastructure improvements along the 144-mile corridor to support both new passenger service and existing freight traffic. The specific upgrades and operational impacts will be detailed in the environmental review and service development plan.
