Pavement on Bay Area streets and roads remains in “fair” condition with an overall PCI of 66. Not only has PCI been relatively stable for the past decade, but 2015 was the seventh consecutive year with the same regional PCI. This is reflective of stagnation in performance gains over the past few years. While local governments continue to work to improve their pavement condition, aging infrastructure remains a challenge for the region.
While the regional trend has been relatively stable in recent years, performance gains are more evident on the county level. San Francisco had the biggest improvement in PCI in the past half-decade, gaining 3 points. Roads in Marin and Alameda counties have also seen improvement in PCI over the past half-decade, while Contra Costa, Santa Clara, Solano and Napa counties have experienced slight declines in countywide PCI.
