Pavement on city streets is only "fair"

Not Jason Henderson's fight

The Metropolitan Transportation Commission gives the pavement on San Francisco's streets only a "fair" rating:

...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.

Seems like we're always voting for more money to maintain city streets (here, here, and here), but the money is supposedly never enough to bring them up to a "good" condition.
