EXECUTIVE SUMMARY
Napa County Public Works staff created a project to apply seal coats to increase the pavement condition of selected roads. The seal coat project covers all or portions of the following County roads: Oak Knoll Avenue, Buhman Avenue, Old Sonoma Road, and Big Ranch Road. Patching of the badly damaged portions of the aforementioned roads will be done before applying the seal coats. Due the condition of Deer Park Road from Highway 29 to Silverado Trail, the contractor would grind the existing pavement, place a pavement fabric and pave the road.
On May 17, 2022, the Board of Supervisors (BOS) approved plans and specifications and authorized the Director to advertise the project to contractors. On June 16, 2022, contractors submitted four bids and Northwest Paving, Inc. of Redding, California, submitted the lowest base bid of $2,355,512. Staff is now requesting a budget transfer to fully fund the project and to award the construction contract to move the project into construction.

ENVIRONMENTAL IMPACT
ENVIRONMENTAL DETERMINATION: Pursuant to Sections 15022(a)(1)(C) and 15300.4 of the State CEQA Guidelines, the Napa County Board of Supervisors have adopted implementation procedures, identifying specific projects that would be categorically exempt from established CEQA Guidelines. The proposed improvements would be considered Categorically Exempt from CEQA pursuant to Section 15301 Class 1-Existing Facilities, which includes the operation and repair of existing public or private structures or facilities involving negligible or no expansion of existing of former use, and is further exempt under Appendix B of the Napa County’s Local Procedures for implementing the California Quality Act.
BACKGROUND AND DISCUSSION
In 2018 Napa County voters passed a half cent sales tax, known as Measure T, to finance the maintenance and repair of existing roads within the limits of Napa County. Experience demonstrates that it is essential to perform preventative maintenance to prolong the life span of a roadway at a lower cost, rather than reconstructing a road after it has failed at 10 to 30 times the cost of preventive maintenance. In order to cost effectively increase the PCI for all Napa County Roads, Napa County will be performing a series of road resurfacing projects during the summer of 2022.
The County’s Pavement Management Program has an inventory of the 420 miles of County maintained roads, the pavement condition index (PCI) of road segments, recommendations of the most cost effective pavement treatments for all the road segments, and budget scenarios. The Pavement Management Program recommends applying pavement cape seals to all or portions of the following County roads in 2022: Oak Knoll Avenue, Old Sonoma Road, Buhman Avenue, and Big Ranch Road. A single cape seal is a single chip seal with a microsurface cape over the chips that will provide a hard and smoother surface.
Because of recent inflation, it was difficult to accurately estimate potential bid prices and thus the advertisement included several alternate bids. The base bids consists of grinding and replacing three-inches of failed pavement at selected areas of the roads, crack sealing, and applying a cape seal over the entire road. In limited areas of Old Sonoma, and Buhman where cracks have grown large, a paving fabric will be used for extra strength. Since Old Sonoma Highway intersects Old Sonoma Road and is in relatively good condition, the work includes a seal. Since Congress Valley Road intersects Old Sonoma Road and is in poor condition, the work will include areas of six-inch deep pavement replacement in areas of severe rutting. Due to the condition of Deer Park Road between Highway 29 and Silverado Trail, there were two separate bid alternatives for paving - one-and-a-half inch grind and replacement and a two-and-a-half inch grind and replacement with a paving fabric. Staff is recommending award of the two-and-a-half inch grind and replacement alternate here.
The contractor will restripe all of the sealed and resurfaced roads with paint until the County places thermoplastic striping next year as a separate project.
