BACKGROUND
The 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 Sates Army Corps of Engineers and later standardized by American Society for Testing and Materials (ASTM). The PCI shows a numerical index ranging from 0 to 100, with 100 being a best roadway condition that is anticipated to support 20 years of use.
Public Works uses the PCI to develop an extended 5-year plan, which is updated annually, to assist in prioritizing road resurfacing projects. Please note, this is not an analysis that selects repairs based on the worst conditions first to be repaired; it is based on repairs that provide the greatest efficacy per budget.

The roads to be included in the project are as follows:
* Solano Avenue, from Locust Avenue (City of Napa limit) to Vineyard View Drive (Town of Yountville limit) (3.2 miles) (PCI varies, as low as 19)
* Big Ranch Road, from Oak Knoll Avenue (east) to the northern end (0.7 miles) (PCI ...
