BACKGROUND
The Public Works Department maintains 420 miles of roads and about 22 miles of guardrail. Over many years, the County has constructed guardrails to help prevent drivers from driving into the Napa River, into creeks, and down roadway embankments. Every year wayward drivers damage guardrails along County roads. In the past, County staff has hired contractors to repair individual damaged guardrails or the Public Works Roads Division staff repaired the damage as time and funding allowed. With the advent of funding from SB-1, the County now designates about $500,000/year towards guardrail repairs.
The annual guardrail repair program provides safety for the public and is a more cost-effective method by repairing numerous guardrails with one construction contract to take advantage of economies of scale. Staff prioritizes the repairs based on safety and available funding and will repair the remaining damage (plus any newly damaged guardrails) in future years. To date, staff has spent about $70,000 on the site inspections and design of this year's project. Currently, staff time is being journaled by the Accounting Department until the project is funded.
The Board authorized advertising for the project on May 7, 2024, and the Clerk of the Board opened bids on June 13, 2024, with the results listed below:
Dirt and Aggregate Interchange, Inc. Fairview, OR $318,888
