The BPMP grant funding requires field review meetings, which include City staff, hired <br /> consultants, and Caltrans personnel. The field reviews must occur during the design <br /> process at intervals prescribed by Caltrans. At the final design field review, it was <br /> pointed out that the work proposed for the Santa Rita Road bridge at Arroyo Mocho <br /> includes approach slab work to address differential movement between the bridge and <br /> Santa Rita Road travel lanes. Since the approach slab work was not identified as a <br /> bridge deficiency in the inspection report, City staff did not think it was eligible for grant <br /> funding. But since the movement has been recurring over the years, causing a <br /> significant "bump" in the asphalt and the need to repeatedly remove and replace the <br /> asphalt to improve ride quality, staff included it in the design work anticipating it would <br /> be funded outside the grant. Upon seeing the need for the work during the field review, <br /> Caltrans determined it could be included in BPMP grant request. City staff then applied <br /> for the additional funding, which Caltrans subsequently approved. However, due to <br /> funding cycle commitments, the funding for design was approved by Caltrans in August <br /> 2017, but the funds needed for construction were programmed by Caltrans for FY 2019. <br /> As a result of the inspection reports and field reviews during the design, the final project <br /> plans as they were advertised for construction bid in April 2020 include the following <br /> work: <br /> 1. Santa Rita Road Bridge at Arroyo Mocho (Br No. 33C-0099) <br /> The scope of work for this bridge includes: adding approach slabs; installing <br /> expansion fittings on the existing waterline at each side of the bridge; removing <br /> the asphalt paving on existing concrete bridge deck; methacrylate deck <br /> treatment; repaving the roadway surface over the bridge; adding joint seals at <br /> Abutments 1 and 3; repairing spalls on bridge deck, the soffit, and concrete <br /> barrier rail; replacing a portion of the concrete barrier and tubular hand railing; <br /> restriping roadway; and reconstructing mortar base at the bottom of chain link <br /> fence posts. <br /> 2. Case Avenue Bridge at Mission Creek (Br No. 33C-0453) <br /> The scope of work for this bridge includes: methacrylate deck treatment; <br /> removing and replacing existing expansion joint seals at Abutments 1 and 2; <br /> repairing unsound grout at railing post pockets; and repairing spalls on the <br /> concrete barriers, deck, soffit, and abutments. <br /> 3. Laurel Creek Drive Bridge at Laurel Creek (Br No. 33C-0454) <br /> The scope of work for this bridge includes methacrylate deck treatment; repairing <br /> spalls on concrete barrier rail and bridge deck; replacing existing expansion joint <br /> seals at Abutments 1 and 4; and reinstalling the architectural treatment on the <br /> barriers. <br /> 4.
