Document Description
San Bernardino County Flood Control District proposed project includes the
installation of a new 84-inch reinforced concrete pipe (RCP) and 96-inch RCP from Edison Avenue to Chino
Avenue. Additionally, the existing 66-inch RCP will be replaced with a 72-inch RCP from Chino Avenue to
just south of the Grove Basin. Furthermore, the project would replace manholes and junction structures,
reconstruct the roadway and associated driveways, and remove existing outlet structures to enhance water
flow management. The pipeline disturbance area has a width of 14 feet and a total pipeline length of 6,583
feet from Edison Avenue to East Riverside Drive. The project also involves an excavation depth of up to a
maximum of 27 feet.
The Project connects to an existing storm drain at the intersection of Edison Avenue and Grove Avenue.
This storm drain ultimately discharges into the Prado Basin and subsequently the lower Santa Ana River.
Night work is not proposed for this project. The estimated construction duration is 160 working days.
Construction activities will take place primarily along Grove Avenue, with site access facilitated from this
main roadway. Lane closures along Grove Avenue may be necessary, including potential traffic detours at
intersections to maintain safety and minimize disruptions during construction operations.
