Document Description
The California Department of Fish and Wildlife is executing Lake or Streambed Alteration Agreement number 1600-2013-0192-R2, pursuant to Section 1602 of the Fish and Game Code to the project applicant, California Department of Transportation (Caltrans).
The structure is an arch culvert on the upstream side, matched to a box culvert at the downstream side, covered with non-bearing wing walls on each side of the bridge (Br No. 11-0097). The facility has one lane in each direction, and staging requires a temporary construction easement on the northern side of the site. Scour has undermined the full width of the slab footing supporting the combined structure. The repaired would inject slurry concrete in the area under the slab that has been scoured out on the downstream side. To prevent future scour, up to 22.4 cubic yards of rock slope protection (RSP) would be situated downstream over fabric to slow water velocity.
