Document Description
Stanislaus County, in coordination with the California Department of Transportation (Caltrans), proposes to perform maintenance on the Las Palmas Avenue Bridge (No. 38C-0033) over the San Joaquin River (see Figures 1-3). The primary goal of maintenance is to clean the existing steel casings that surround the concrete bridge columns between piers 4 and 8. The cleaning will remove the sections of corrosion on those piers and then install new supplemental grouted steel column/pile encasements around the existing steel casings. These new encasements would both strengthen the piles and protect them from further corrosion. The proposed new encasements would be installed to cover a minimum of three feet beyond the limits of the existing corrosion for both the normal high and low water conditions. Rehabilitation of these piles would not substantially reduce the area between the piles which would ensure channel flow is not obstructed. A preliminary design detail of these casings is included in Figure 4. See NOC for full document description.
