BACKGROUND
During the storm event that started in January of 2023, significant damage occurred at Mt. Veeder Road MPM 3.99, which is located in the 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 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 are 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).
On January 24, 2023, the Board adopted a Resolution ratifying a Proclamation of Local Emergency and appropriated $1,000,000 funding for the design and repair of Project 23037 (Mt. Veeder Road MPM 3.99, RDS 23-23). This project may qualify for Federal Emergency Management Agency (FEMA) funding and the County will request for reimbursement. If approved, the match for this project is 75% FEMA, 18.75% California Office of Emergency Services (Cal OES) and 6.25% local.
The Engineer’s Estimate for the Mt. Veeder Road MPM 3.99 is $816,000. The Plans and Specifications are complete and ready for approval by the Board of Supervisors. The Director is requesting authorization to advertise for bids. Staff will return to the Board of Supervisors at the time of construction to present a detailed project budget based on the lowest responsible bid and to request a budget amendment to fund construction.
Requested Actions:
1. Approve Plans and Specifications for the “Mt. Veeder Road MPM 3.99, RDS 23-23” and authorize to advertise for sealed bids.
