We had to remove the large, dying, maple from our yard over the weekend.  Some large branches came out during wind storms last year and the risk that the whole tree would fail was possible.  One expert gave it less than a year.  A few years ago, its output of leaves filled our utility trailer multiple times over.  This year, the leaves would have fit in a single can.  While this is not a street tree, there is an interesting article here about the value of Portland street trees and their effect on real estate.  We planted four mature trees about 4 years ago from bigtreestoday.com.  Three are doing really well, one is hanging in there.
