- Document Description
- The primary purpose of the Project is to replace two failing culverts with one concrete box culvert and stabilize the banks at the inlet and outlet. The proposed Project would include replacing two existing 48" x 45' perched culverts with one 10' x 6' x 45' concrete box culvert. The new culvert will be countersunk two feet below stream grade and backfilled with existing native streamed material. The new culvert will widen and enhance channel capacity and function. Cast-in-place wing walls will be constructed at the upstream and downstream ends of the new box culvert.
