Document Description
On January 4, 2023, Governor Gavin Newsom proclaimed a state of emergency throughout the State of California to support the response to historic rain and flooding. Heavy rains saturated soils and triggered a sinkhole and culvert failure along Canada Road that requires immediate repair.
Emergency repairs for the culvert near Filoli will include removal of the existing failed CMP and replacement in the same alignment along approximately 35 linear feet of the damaged area. The new pipe would be reconnected to the existing headwall, if possible. The sinkhole above the failed culvert will be backfilled and compacted. Minor grubbing and tree trimming will be associated with the repair.
Post-construction erosion control BMPs will be installed to conserve soil resources and protect water quality. All temporary surface disturbances will be seeded with native plants. Work will be conducted in accordance with BMPs detailed in the County of San Mateo Routine Maintenance Program Manual.
