BACKGROUND
Roads planned for rehabilitation are selected based on their existing Pavement Condition Index (PCI), which is an overall measure of the condition of the road surface developed by the United States Army Corps of Engineers and later standardized by the American Society for Testing and Materials (ASTM). The PCI shows a numerical index ranging from 0 to 100, with 100 being the best roadway condition that is anticipated to support 20 years of use.
Public Works uses the PCI information to develop a 5-year plan which optimizes the use of available funds to assist in prioritizing road resurfacing projects. This is not an analysis that selects repairs based on “worst first.” Instead, it is based on repairs that provide the greatest efficiency per dollar spent. In many cases spending smaller amounts of money on maintenance towards roads that aren’t in bad shape can be much more effectively spent than a larger funding amount towards a road that has already failed.
The roads to be included in the project are as follows:
Deer Park Road (4.07 miles) (PCI 51)
Sanitarium Road (1.75 miles) (PCI 41)
Glass Mountain Crossroad (0.11 miles) (PCI 52)
White Cottage Road (3.83 miles) (PCI 28)
College Avenue (0.82 miles) (PCI 43)
On June 25, 2024, the Board approved project creation of the Deer Park Region and West Zinfandel paving project which included rehabilitation of the following roads: Deer Park Road, Sanitarium Road, Sunnyside Road, Glass Mountain Crossroad, and West Zinfandel Lane. The project was planned for construction in 2025. However, during design coordination staff discovered that both Pacific Gas and Electric and the St. Helena Hospital have ongoing and scheduled utility underground project in the area in 2025. Therefore, the paving project was postponed until 2026, to allow completion of the underground work prior to paving. West Zinfandel has since been constructed under a separate paving project as it had no known utility undergrounding project conflicts. With the removal of West Zinfandel from this project, this project’s name has been changed from the “Deer Park Region and West Zinfandel Paving Project” to the “Deer Park Region Paving project.”
On October 21, 2025, the Board approved Amendment No. 2 which incorporated White Cottage Road and College Avenue into the project as they are both in the vicinity of Deer Park Road. Staff determined that including these roads in the “Deer Park Region Paving Project” would be more efficient and cost effective than rehabilitating them as part of a later project. This project is proposed to be constructed this summer and will include Deer Park, White Cottage, College, and Glass Mountain Crossroad. Sanitarium will be included as an “additive alternate”, but it is not believed we have sufficient funds to accomplish that this year. Sanitarium will most likely be paved in 2027 instead. Also, the Roads Department is working on a separate project for Sunnyside and Mund.
The estimated construction cost for this project is $6,000,000. Finals costs will be confirmed through the competitive bidding process.
The plans and specifications for the “Deer Park Region Paving Project” are complete and ready for approval by the Board Supervisors to be advertised. Project plans and specifications are available to view on the <https://www.napacounty.gov/1607/Current-Projects> website. Staff will return to the Board at a later date to request approval of the contract award based on the lowest responsible bid and to request a budget amendment to fund the project through construction.
Requested Action:
1. Approve Plans and Specifications for the “Deer Park Region Paving Project,” RDS 25-02 and authorize advertisement of sealed bids.
