BACKGROUND
On January 23, 2024, the Board awarded a construction contract to Gordon N. Ball of Alamo, CA for the Chiles Pope Valley Road Bridge over Chiles Creek Project, RDS 15-23. Gordon N. Ball’s bid was $6,246,113 and at award the Board also approved a budget amendment of $9,181,038 to fund the construction. The Chiles Pope Valley Road Bridge over Chiles Creek Project is approximately 2.1 miles north of Highway 128 and was replaced in the spring, summer, and fall of 2024, and only minor bridge construction work remains. One such item remaining is to install the irrigation system and plants for the California Department of Fish and Wildlife (CDFW) required mitigation.
Due to the work in Chiles Creek, Napa County entered into Lake and Streambed Alteration Agreement No. NAP-30757-R3 with the CDFW, and it includes mitigation measures to limit temporary and permanent impacts of the bridge replacement. The CDFW agreement prescribes restoration practices be implemented and monitored for up to ten (10) years.
In prior reports to the Board, staff described the need to implement the restoration and monitoring in the CDFW Agreement for this project. The proposed Chiles Pope Valley Road Bridge Replacement Restoration and Monitoring Project Plans and Specifications will implement the required environmental restoration and begin the first phase of monitoring required under the CDFW Agreement.
After the bid opening, staff will ask the Board to award the construction contract for the restoration and monitoring work.
Requested Action:
