Seven Oaks Bridge Project (Notification of Lake or Streambed Alteration, No. EPIMS-SBR-61708-R6)

The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-SBR-61708-R6, pursuant to Section 1602 of the Fish and Game Code to San Bernardino County Public Works Department. The project is limited to installing a new bridge, slope protection measures (e.g., rock slope protection), and improving the roadway approaches. The permanent bridge and roadway approach have been designed to handle 100-year flood events. The project will require a temporary detour route to maintain ingress/egress for nearby residents, in water work consisting of installation of temporary culvert extensions to support the temporary road, and rerouting of the Santa Ana River to return the flow to its pre-storm alignment under the new permanent structure (approximately 60 feet to the northwest of the current flow). To minimize impacts to the Santa Ana River, water will continue to flow through the existing culverts that were installed during the emergency repairs. The water will be diverted back into its original alignment as part of the Project.
