HYDROLOGY AND HYDRAULIC STUDY OF THE SAN GABRIEL SUBDIVISION RFP
The San Bernardino County Transportation Authority is soliciting proposals for a hydrology and hydraulic study of the San Gabriel Subdivision railroad corridor, and this is a consultant-services RFP rather than a grant program. The study will evaluate flood risk from Mile Post 45.75 to Mile Post 54.5, including vulnerabilities caused by contributing channels, culverts, and drainage conditions affecting the railroad right-of-way. The solicitation is currently open for electronic responses, and final engineering and construction design are excluded from the project.
