BACKGROUND AND DISCUSSION
The County roads in the Angwin area have deteriorated over the years due mainly to aging and normal wear and tear. The Angwin Area Paving Project will repair and resurface the highest priority roads based on available budget and maximizing community benefit. The highest priority roads for this project are the two main roads serving Angwin and connects Silverado Trail to Chiles Pope Valley Road: Deer Park Road (DPR) and Howell Mountain Road (HMR).
During preliminary design, staff reached out to utility companies to coordinate any contemplated construction they may have for the area. As a result, improvements to various interior roads in Angwin are scheduled for 2024 to allow PG&E to complete a possible undergrounding project, and DPR will be scheduled for 2025 to allow PG&E to complete a possible undergrounding project and for the St. Helena Hospital to complete a water line project. Therefore, this proposed project will focus on HMR from its intersection with DPR/White Cottage/ Old Howell Mountain Road (this intersection is often referred to as “four corners”) to Chiles Pope Valley Road, which is approximately 5.9 miles of roadway.
The project design will consist of performing dig out repairs of severely alligatored areas of the roadway, some areas of full road width grinding, and placement of three inches of asphalt. Additionally, the project will restripe all markings, provide additional shoulder backing in some areas, and incorporate some additional signage to increase public safety. Construction of the above noted work is approximated at $4.21 million and is anticipated to be completed in summer 2023. The proposed project will be funded through a $2M appropriation courtesy of Senator Dodd and available Measure T funds.
Today’s action by the Board of Supervisors (Board) will allow staff to bid the project with an anticipated bid opening in June. Staff will return to the Board at a future date for award of a construction project and will present a detailed project budget based on the lowest construction bid with a request for a budget transfer to fully fund the project.
