BACKGROUND
The Upper Partrick Road Rehabilitation Project will repair approximately 0.9 miles of Partrick Road beginning near address 1766 and extending west to the point where the road narrows to a single lane. Roads are selected for rehabilitation based on their Pavement Condition Index (PCI), which is a numerical index ranging from 0 to 100 that measures pavement condition. The PCI for this segment of Partrick Road is approximately 29, indicating a roadway in poor condition requiring rehabilitation. This segment of roadway is severely deteriorated and is experiencing several slow-moving slides, deep pavement cracking, and areas of significant pavement distress.
The project will improve drivability and long-term roadway stability. The proposed work includes construction of limited stitch pile retaining walls at locations where roadway movement has been observed and where slope instability poses the greatest risk to the roadway. Pavement sections exhibiting the most severe distress will be leveled with new asphalt concrete, and the roadway will receive a full overlay to extend the life of the pavement. Three culverts will also be replaced.
On December 3, 2024, the Board of Supervisors approved creation of the “Upper Partrick Road Rehabilitation Project” and a budget amendment to fund design and construction of the project. The plans and specifications are complete and are ready for approval by the Board of Supervisors. The project plans and specifications are available to view on the https://www.napacounty.gov/1607/Current-Projects website. Upon approval, Public Works staff will advertise the project for bids and return to the Board at a later date to request authorization to award the construction contract.
Construction of the project is anticipated to occur during the 2026 construction season.
Requested Action:
Approve the Plans and Specifications for the “Upper Partrick Road Rehabilitation Project,” RDS 24-37 and authorize advertisement for sealed bids.
