BACKGROUND
The Chiles Pope Valley Rd MPM 3.63 Project (RDS 22-27) and Silverado Trail at Bell Canyon Creek Project (RDS 23-37) are two different project activities that are utilizing the same project number, 23006. On August 9, 2022, Napa County entered into Agreement No. 230084B with ADKO to obtain engineering design and consulting services for the Chiles Pope Valley Rd MPM 3.63 and Silverado Trail at Bell Canyon Creek projects. Since the original agreement, the County has issued three (3) amendments to the Agreement due to the evolving scope required for both projects.
