RFP - Drainage Study and Analysis for the El Dorado Drainage Improvement Project #36106004

The contract involves a partnership between the County’s Department of Transportation and the El Dorado Water Agency to conduct a comprehensive drainage study for the Slate Creek watershed and drainage infrastructure in the town of El Dorado, with a focus on addressing historic flooding issues. The project is divided into two phases: the first encompassing the overall watershed, and the second concentrating on infrastructure improvements along Pleasant Valley Road, specifically within an 800-foot stretch from Hinman Alley to Oriental Street. The primary goal is to evaluate current drainage conditions, identify deficiencies, and develop a detailed plan for upgrading and restoring the drainage system to mitigate flooding risks effectively. The project emphasizes the need for a detailed assessment of existing infrastructure, which is nearing the end of its service life, and will serve as the basis for designing necessary improvements.

Proposers must submit comprehensive responses including certifications, experience narratives, and detailed work plans. The process involves evaluating firms’ technical expertise, financial stability, and past performance, with specific emphasis on familiarity with local regulations, Caltrans procedures, and project management capabilities.
