To introduce the PCI concept – we use a
0-100 scale, with 0 = failed condition, and 100 = excellent condition.
What we decide as acceptable depends on the City. The analogy I use is the math
grade your child brings home from school – 80 may be acceptable to one parent,
but not to another. Similarly, what the acceptable PCI should be for a City’s
network is a policy decision.
However, in general, if a City were to fall below 70, it would be very expensive
to make any significant improvements. Use Santa Cruz as an example.
