My guess would be that you're speaking of W. 9th in the Springfield neighborhood? Springfield is a Northside neighborhood going through gentrification.
You can find out more info about Springfield from their neighborhood preservation website/forum:
Welcome to Historic Springfield!
There's also some info here:

If you lived in a similar neighborhood in Portland, you'd probably love Springfield. If you've never lived in a neighborhood going through the process, you might want to have a few other neighborhood options in mind in case you don't want to make the commitment to a neighborhood going through transition.
