Document Description
The Department is issuing a 1602 Streambed Alteration Agreement to the project proponent, who proposes to correct the scouring problem at the I-10 westbound Willow Wash Bridge by retrofitting the existing footings. The bridge has been classified as scour critical with a code rating of #3; "bridge foundation determined to be unstable for calculated scour conditions." The work will consist of retrofitting the upstream (north side) footings of benets 2 and 3 by driving piles and constructing two concrete check dams. A temporary access ramp will be constructed off of I-10, 100 feet west of the bridge, to allow the contractor's equipment to go down the streambed and get in and out of the wash. All work will be performed within the existing State right of way. The project will result in 0.0023-acre of permanent impacts and 0.25-acre of temporary impacts to the unvegetated streambed.
