Fort Jim Road Sinkhole
The existing 9-foot diameter structural steel plate pipe culvert under Fort Jim Road at the South Fork of Weber Creek failed during the 2017 winter storms resulting in a sinkhole on Fort Jim. This FEMA funded project replaced the 9-foot culvert with a 22-feet by 9-feet 4-inches precast concrete arch bridge and precast headwalls and wingwalls. Gina was in responsible charge of the project and oversaw the construction inspection services of the work which included removal of 12-inch plastic pipe, roadway excavation including the removal of the County’s temporary repair area, installation of 18-inch RCP, installation of 4-inch PVC utility conduit and 4’ square manhole for new AT&T line, stream diversion, rock slope protection and rolled erosion control blanket, placement of new structural section, paving, striping, and full road closures. She monitored compliance with the contract plans, as well as recorded/reported all construction activities, and maintained all project records with Caltrans and Federal funding standards.
