The Riverside Transmission Reliability Project was jointly proposed by Southern California Edison and the City of Riverside to increase electrical reliability within the City of Riverside by providing a second interconnection point into the bulk power system. Southern California Edison’s portion of the project involved construction and operation of a 10-mile long, double-circuit 230-kV transmission line and new substation within the City of Jurupa Valley, City of Riverside, and unincorporated Riverside County. In 2012 the City of Riverside prepared an EIR to analyze impacts of the entire project. The City of Riverside approved the city-owned segments of the project in 2013. Southern California Edison modified segments of the 230-kV transmission line after filing its application to the Public Utilities Commission.

Panorama prepared a Subsequent EIR to address changes to the project after certification of the EIR. The Subsequent EIR required extensive public outreach due to the complex and controversial project history. Panorama led public meetings to facilitate conversation with the public. Panorama translated public outreach materials into Spanish and provided Spanish, Mandarin, and Cantonese translation services at public meetings. Panorama consulted with the City of Jurupa Valley regarding concerns related to aesthetic and traffic impacts, as well as project alternatives. Panorama screened a total of 31 alternatives and analyzed four alternatives at the same level as the proposed project.
