San Mateo County and its 20 cities largely improved the quality of the pavement on their local street and road networks in 2018, with Burlingame, Menlo Park and Woodside registering the biggest year-over-year improvements; and Colma, Daly City and Foster City boasting some of the smoothest streets in the Bay Area. Data released today by the Metropolitan Transportation Commission (MTC) show San Mateo County’s nearly 4,000 lane-miles of city streets and county roads registered an average pavement condition index (PCI) score of 72 out of a maximum possible 100 points last year, as calculated on a three-year moving average basis. This puts the typical stretch of Peninsula asphalt in the “good” range, and local officials expect the county’s PCIs scores to rise further in the years ahead.

“2018 was the first full year that state Senate Bill 1 delivered new street and road money to the county and our cities,” explained San Mateo County Supervisor and MTC Commissioner Warren Slocum, referring to the transportation funding package approved by the state Legislature in 2017.  “Pavement quality across San Mateo County is generally pretty good, and we now have a continuing investment that will make our best roads even better while also allowing local governments to do some needed catch-up.”

            PCI scores of 90 or higher are considered “excellent.” Pavement with a PCI score in the 80 to 89 range is considered “very good.” The “good” category ranges from 70 to 79, while streets with PCI scores in the “fair” (60-69) range are becoming worn to the point where rehabilitation may be needed to prevent rapid deterioration. Because major repairs cost five to 10 times more than routine maintenance, these streets are at an especially critical stage. Roadways with PCI scores of 50 to 59 are deemed “at-risk,” while those with PCI scores of 25 to 49 are considered “poor.” Pavement with a PCI score below 25 is considered “failed.”  Three-year moving average PCI scores for all San Mateo County jurisdictions are listed below:
