The City has over 850 miles of streets and paved nearly 400 blocks last year, but underfunding has led to a gradual decline in our pavement conditions since 1988. The standard measurement of street quality, a 100 point scale called the pavement condition index (PCI), shows San Francisco streets are currently at 64 – this is below the state average and more expensive to maintain than a best practice level of 70.
The table below explains the costs and associated treatments made based on the PCI score. Review the table and map to find your street’s PCI!
You can also learn more about the challenges facing streets or find out if your street is up for repaving.
| PCI Score | Map color | Associated Treatement | Cost/Block | Image |
|---|---|---|---|---|
| 100-85 | Black | No action needed | - |  |
| 84-64 | Blue | Maintenance: crack or slurry seals are used to repair distress and reinforce weakened pavement | $9,000 |  |
| 63-50 | Orange | Resurfacing: surface layer is grinded and filled with a new layer (mill and fill) | $97,800 |  |
| 49-0 | Red | Reconstruction: surface layer is grinded, base is repaired, surface layer is replaced (mill and fill w/base repair) | $138,000 – $436,400 |  |
