How to report potholes in the roads?

There's a big pothole on my street, how do I get it fixed?

from Joan Lowenstein as posted to WBWC:

Riding Ann Arbor's streets on a bicycle, you certainly see where some
of the problem areas are with our streets. This has been a
particularly hard winter and the city council has actually had to
appropriate more money for fixing potholes and other road problems. I
am going to try to have the city set up a place on the website where
cyclists can post pieces about areas that they find very troublesome.
For example, I had to ride down to S. State Street yesterday and
there's a really bad spot under the bridge, just north of Stimson.
Would others be willing to be "eyes and ears" for our under-staffed
city road crews?
