Comment(by mikepease):

 Here's a list of addresses on a street in Minneapolis that illustrates
 this northward shifting. These addresses can be seen on the attached map
 dated 9-19-11 near 32nd Street and 32nd Ave.

 Notice the higher the address number, the more northward shifting there
 is. Could this be an interpolation issue between 3200 and 3299? Maybe
 you're presuming the address could go up to 3299 when it really only goes
 up to let's say 3270 (for example).

 Another note, these are South-side of downtown addresses (direction
 suffix). I noticed some Northeast suffix addresses had an opposite
 Southward shifting. A possible clue? Interpolation issue going the
 opposite direction?

 Here's that list of addresses and the distance shifted from Google.
