Document Description
Proposed work is to repair and reconstruct damaged highway facilities resulting from debris flows and other rain related damage from the storm of January 27th and 28th on Highway 1 in Monterey County south of the Rat Creek washout. The Governor declared a state of emergency for Monterey County on January 29, 2021 given the extent of damage caused by this rainfall event. On January 27,2021, an early morning storm began to pass over the Big Sur Coast. The storm front stalled, became an atmospheric river, led to higher than usual rainfall totals for the area, and caused fire debris and surface material to inundate many of the drainage systems that cross the Highway 1. Many cut slopes above the highway had surface material and fire debris that washed down during the rain event. The scope of work is for the contractor to clear the mud and debris from the highway, clear culvert inlet areas of debris and mud, clear culverts impacted by debris flows, and allow Caltrans forces to assess the condition of inlets, redundant inlet features, and culverts impacted by debris flows. The main items of work include: • Clear inlet areas and dispose of the debris and mud • Vactor culverts to clear debris and mud • Repair and enhance inlet redundancy features • Clear debris and mud from the highway and catchment areas • Remove debris from behind rockfall protection systems • Repair rockfall protection systems • Repair highway prism scour • Realign highway away from eroded fill slope • Repair/Rehab/Replace damaged culverts as needed • Remove Debris from Bridge Bents and Abutments • Install inlet protection and redundancy features • Install down drains • Place erosion control measures • Provide temporary traffic control
