The project involves filling voids beneath the existing culvert invert with grout, paving the invert with an eight-inch thick layer of concrete, constructing a headwall at the culvert inlet, installing rock slope protection (RSP) around the inlet, and removing select steel members of the existing debris catcher. Heavy equipment, such as backhoes and concrete pumping trucks, will be operated from temporary access roads that will terminate above the stream banks. A temporary sandbag diversion dam will be installed at a natural bottleneck in the stream located approximately 30 feet upstream of the culvert inlet. A temporary containment dam will be installed approximately 10 feet downstream of the culvert outlet.
