The Sonoma County Board of Supervisors on Tuesday endorsed a plan to increase the network of county roads designated for long-term maintenance by 63 miles, about 5 percent of the 1,382-mile network.
The move, which requires formal adoption at a later date, would bring the county's so-called priority road network — the routes identified for long-term maintenance because of their federal funding or importance for regional travel — to 219 miles, roughly 16 percent of the total network.
The added miles — representing 39 roads — include a 5.4-mile stretch of Bennett Valley Road from Grange Road to Warm Springs Road, a stretch that Bennett Valley residents lobbied to have restored to the priority network.
Other major segments to be added include 8.2 miles of Valley Ford Road from Highway 1 to Tomales Road and 6.1 miles of Graton Road from Bohemian Highway to Highway 116.
Most of the segments are in good shape now, and the aim is to focus long-term maintenance efforts on them to keep them that way, said Phil Demery, director of the county's Transportation and Public Works Department, which prepared the plan.
