BACKGROUND
During the storm event that started in January of 2023, significant damage occurred at Mt. Veeder Road MPM 3.99, which is in unincorporated Napa County. Mt. Veeder Road MPM 3.99 sustained road and fill failure consisting of downslope failure on the northern side of the roadway, where a portion of the road slid down the hillside threatening the remaining portions of the road. The slide is approximately 100 feet long by 12 feet wide.
The proposed repair to the slide is an approximately 142-foot-long concrete grade beam wall supported by 24" concrete CIDH (cast-in-place-drilled-hole) piles. The grade beam wall depth is between 6 feet to 8 feet. The piles depth is approximately 20 feet. There will be approximately 20 linear feet of roadway pavement rehabilitation (grinding and re-surfacing existing pavement) and 165 linear feet of roadway pavement re-construction (removing old asphalt/aggregate base and replacing with new asphalt/aggregate base).
