California Department of Transportation (Caltrans) and the Los Angeles County Metropolitan Transportation Authority (Metro) are planning to construct a multipurpose corridor in California, the US.
The project involves the construction of 101km multipurpose transportation corridor between State Route (SR)-14 in Los Angeles County and SR-18 in San Bernardino County. It includes the construction of roads, pavements, carriageway and related infrastructures.
In April 2010, the Metro Board authorized entry into a Memorandum of Understanding (MOU) for the implementation of the High Desert Corridor (HDC) Project. This MOU identifies the roles and responsibilities of the project partners.
Partner agencies include the HDC Joint Powers Authority (HDCJPA), the Southern California Association of Governments (SCAG), the San Bernardino Associated Governments (SANBAG), the State of California represented by the Department of Transportation (Caltrans), the County of Los Angeles and the County of San Bernardino.
In September 2010, Caltrans, Metro, SANBAG and partner agencies initiated the Alternatives Analysis (AA) and Draft Environmental Impact Statement/Report (Draft EIS/EIR) to evaluate alternatives.
In January 2012, Metro and Caltrans held public meetings for the proposed project. In February 2014, Metro and Caltrans conducted webinars (a seminar conducted over the Internet) for the fifth alternative.
In October 2014, Metro and Caltrans held series of public meetings for selection of preferred alternative for the project.
Caltrans and Metro have completed the Draft EIS/EIR in late 2014.
Metro and Caltrans studied five functional alternatives and four physical variations in the Draft EIS/EIR including Freeway/Expressway Alternative, Freeway/Tollway Alternative, Freeway/Expressway with High Speed Rail (HSR) Feeder Service Alternative, Freeway/Tollway with HSR Feeder Service Alternative, and the No Build Alternative.
1. Freeway/Expressway Alternative (Avenue P-8, I-15, and SR-18): This alternative would construct a combination of a controlled-access freeway and at-grade expressway for a total distance of 101km.
2. Freeway/Tollway Alternative (Avenue P-8, I-15, and SR-18): This alternative would follow the same route as the Freeway/Expressway Alternative (with variations A, B, D, and E), but it would have sections that operate as a tollway.
3. Freeway/Expressway Alternative with High-Speed Rail Feeder/Connector Service: This alternative would be the same route as the Freeway/Expressway Alternative, but it also includes an HSR Feeder Service between Palmdale and Victorville. Variations A, B, D, and E were considered, but Variation A was later determined to be not a viable variation for the alternatives with HSR due to some geometric constraint.
4. Freeway/Tollway Alternative with High-Speed Rail Feeder/ Connector Service: This alternative would follow the same route as the Freeway/Tollway Alternative (including Variations A, D, B and E), but it also includes an HSR Feeder Service between Palmdale and Victorville. Similar to the Freeway/Tollway Alternative, the bicycle facility and green energy components would be incorporated into the design features of this alternative.
5. No Build Alternative: Under the No Build Alternative, no new transportation infrastructure would be built
within the project area to connect Los Angeles and San Bernardino counties, aside from existing SR-138 safety corridor improvements in Los Angeles County and SR-18 corridor improvements in San Bernardino County.
In July 2015, Caltrans and Metro have identified the Preferred Alternative (PA). The PA is a multipurpose alternative that includes Freeway/Tollway with High Speed Rail in the Median along with the Green Energy Corridor and the Bikeway.
The PA includes two previously considered variations (Variations D and B1) as part of the alignment.
Variation D - located in Lake Los Angeles, will reduce the number of residential displacements and avoid an existing vineyard.
Variation B1 – located in Adelanto, will avoid impacts to several water wells owned by the Phelan Piñon Hills Community Services District.
Enviro Metro has been appointed as environmental consultant.
In June 2016, Caltrans released the final environmental review for the project.
