Document Description
The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement number 1600-2004-0493-R5 pursuant to Section 1602 of the Fish and Game Code to the project applicant, California Department of Transportation. The applicant proposes to alter the streambed to widen SR 138 from an existing 2-lane highway to a standard 4-lane highway for segment 11 (146th to 165th Street East) Including the replacement of the existing bridges at Big Rock Wash to a standard one span bride with 4 lanes and a median. The project includes the removal of the two trapezoidal channels and the existing levee. The highway will be raised to accommodate drainage culverts and revegetating the area. The drainage work includes a longitudinal trapezoidal channel, which will parallel the highway on the south side and outlet in Big Rock Wash. Rock slope protection will be placed upstream and downstream of the bridge. Big Rock Wash will be 80 ft. wide at the base with side slopes at a 1:6 ratio. Culverts will be placed under the roadway in various locations. A concrete slab (apron) will be placed under the bridge. A temporary roadway will be constructed parallel to the existing highway on the north side of the roadway with arch culverts no less than 36" in height to allow for wildlife movement. The proposed road will be 500 feet long by 24-40 feet wide. The temporary road crossing in the wash will impact 1.6 acres. The project is located in the unincorporated area in Los Angeles County.
