Project Overview
The City of Bainbridge Island maintains a 140-mile road network. Each year, the City receives an average of $650,000 for roads and repair projects. The budget includes $400,000 from the Transportation Benefit Fund (TBF or car-tab fees) revenues, and the remainder is supported by the City’s Street Fund.
The 2022 road work included grinding and paving. This technique provides a long-term fix for uneven pavement or other defects in the road and creates a smoother surface for driving. The pavement comprised new and recycled on-site materials that meet the Washington State Department of Transportation requirements for mix design.
Road Assessment
The City uses a Pavement Condition Index (PCI) and traffic volumes to rate the conditions of the road network and to determine where road maintenance will happen. The PCI ranks the overall health of a pavement segment on a scale of 0 to 100 (0 represents a failed street; 100 represents a new street). The PCI rating is determined by a visual inspection of pavement condition, age, and distress.
As of the 2019, the City's average PCI score is 70. The current score reflects the fact that many of our high-volume roads are in good shape, but many smaller low-traffic roads are in need of repairs. The City strives to keep the higher-volume roads from deteriorating while addressing smaller roads—and the associated neighborhood concerns— over the long-term. The City’s last pavement condition report recommended spending a minimum of $1 million annually on pavement preservation.
