About this file
This is an Addendum 1 to a Request for Proposals issued by the California Department of Transportation (Caltrans) District 11 for the Salton Sea West Flood Resilience Study. The addendum modifies the original solicitation for a comprehensive engineering and planning study addressing recurring flood and washout events along the west side of the Salton Sea on Routes 78 and 86 in Imperial County, extending 10 miles into Riverside County. The study focuses on developing long-term, proactive solutions to mitigate climate-related flooding impacts in an area that has experienced nine separate emergency projects costing approximately $5 million over the past decade. The study area encompasses roadway segments serving the Torres Martinez Desert Cahuilla Indians and disadvantaged communities, with precipitation events expected to increase 8.2 percent by 2085. The addendum clarifies project requirements, evaluation criteria, and submission procedures for interested bidders responding to the original RFP.
The addendum establishes or modifies key contractual terms, evaluation methodologies, and technical requirements governing the selection process and contract performance. Specific modifications outlined in the addendum address bidder questions, clarify scope elements, and adjust submission deadlines or documentation requirements to ensure comprehensive responses to the flood resilience study needs. The contract funding and sources are identified through Caltrans District 11's capital improvement budget, reflecting the state's commitment to addressing critical infrastructure resilience and climate adaptation in this disadvantaged community. Prospective bidders must carefully review both the original RFP and this addendum to understand all requirements, qualifications, and technical specifications necessary for proposal submission and evaluation.
