Document Description
The proposed project involves retrofit measures to extend the existing partial scour walls to the bridge soffit by constructing new infill walls between the columns at Piers 4 to 12 and installing pipe seat extenders at both expansion joints to the bridge to help control movement of the bridge deck during a seismic event. Two pre-cast flumes would be installed between selected bridge piers to provide fish passage through the riprap underneath the bridge. Each flume would be three-sided and approximately 75 feet long by 26 feet wide by 3.5 feet deep. A new wildlife crossing (pathway composed of gravel or sand) would be installed along the south side of the channel between Piers 4 and 5. The proposed project is located on Douglas Drive crossing over the San Luis Rey River and is within the North Valley and San Luis Rey Neighborhood Planning Area in the City of Oceanside.
