Document Description
The Project will replace an existing culvert to provide fish passage at the Rohnerville Road crossing, a barrier for all life stages of salmonids on Jameson Creek. The Project includes a precast reinforced concrete box (RCB) culvert, approximately 12'H x 14'W, with a roughened channel constructed within the culvert, and extending approximately 120 feet upstream and downstream, to provide a natural stream bottom. The existing roadway will be excavated to remove the existing culvert, and the new culvert will be set approximately 3 feet below the channel thalweg to accommodate backfilling with stream bed material. The precast box culvert will be placed in sections and will require subgrade preparation prior to installation. Once the RCB is placed, the roughened channel will be constructed by placing rock from both ends of the culvert or alternatively from above the culvert, should the contractor choose a culvert with removable top sections allowing rock placement from above. The roadway fill prism will then be brought back up to grade, and all existing utilities within the fill prism will be replaced.
