Making the most of limited funding
The Department of Transportation & Public Works is responsible for maintaining about 1,379 miles of roads outside of cities in Sonoma County.
It would cost $58 million every year for 10 years to bring these roads to a level where they can be maintained at a lower cost through best management practices. Sonoma County is not alone, it would cost $7 billion every year for 10 years to bring all local roads in California into this condition.
From 2012 - 2017, the Board of Supervisors (Board) dedicated over $65 million local dollars to paving. This investment will contribute to paving about 300 miles of roads. Roads are typically funded with state gas tax, however for years the state gas tax did not fully covered mandatory maintenance, and left no money for paving.
Sonoma County is one of the leading Counties in the State of California to dedicate local, discretionary General Fund dollars to roads. In 2017, the State Legislature approved new funding for roads, which will raise our total state revenue to over $20 Million when fully phased in, more than double the current allocations from the State.
Despite this contribution of local funds and new state gas tax, there is still a significant funding shortfall for roads. With such an extensive road system and limited funding sources, we must strategically select roads for pavement preservation treatments.
How are roads selected?
A list of roads is developed every year, to be resurfaced during the following year's Pavement Preservation cycle. The selection process takes multiple criteria into consideration, including pavement condition, type and amount of usage, design characteristics, as well as geographic distribution of projects. These factors are described in the next section, and the Long Term Road Plan (PDF).
