The Mid County Parkway is a proposed 16-mile transportation corridor that will relieve traffic congestion for east- west travel in western Riverside County between the San Jacinto and Perris areas and help address future transportation needs through 2040.

The Riverside County Transportation Commission (RCTC), the agency responsible for transportation in Riverside County and the administrator of Measure A (Riverside County's 1/2 cent sales tax for transportation), has completed the environmental studies for the modified alternatives for the Project.


The Recirculated Draft EIR/Supplemental Draft EIS (RDEIR/SDEIS) evaluating the modified alternatives from I-215 to SR-79 was prepared and circulated for a 75 day public review period in January 2013 and a public hearing was held in February 2013. Revised sections of Chapter 4 of the RDEIR/SDEIS were prepared and circulated for a 45 day public review period in January 2014. Electronic copies of both documents are available on this website under "Library/Links."

Following completion of the public review of the RDEIR/SDEIS the Final EIR/EIS was prepared and finalized with concurrence from all the agencies (FHWA, Caltrans, USACE, USFWS, USEPA, and CDFW) involved in the MCP project. The Final EIR/EIS includes responses to comments on the January 2013 RDEIR/SDEIS, the January 2014 revised sections of Chapter 4 of the RDEIR, and identifies the preferred alternative.

On April 15, 2015, FHWA as the lead agency under NEPA approved the Final EIS and, following a 30-day review period of the Final EIS from April 24 - May 26, 2015, approved the Record of Decision (ROD) for the MCP Project on August 17, 2015. new

The Final EIR/EIS and ROD are available electronically on this website under "Library/Links." new

Copies of the Final EIR/EIS and ROD are available at public locations listed in the "Library/Links" section of this website. new


On August 26, 2015 a Notice of Limitation on Claims under NEPA was published in the Federal Register. new Click here

Now that the ROD is approved, the project can begin the Right of Way Acquisition and Plans, Specification & Estimates (PS&E) Phases. new

During the PS&E phase, RCTC and FHWA will work on compliance with state / federal permitting requirements and regulations as well as complying with the mitigation measures and other environmental commitments stipulated in the Final EIR/EIS and ROD in order to begin construction.
