OC Public Works manages 372 miles of roads in unincorporated Orange County. Their pavement management program uses surveys to evaluate pavement condition and determine appropriate maintenance approaches. Funding comes from various federal, state, and local sources. They analyze funding scenarios and contract work using methods like job order contracting to efficiently maintain roads and increase the pavement condition index over time. Recent state funding from SB1 may help further improve conditions.
