Plus a broken sewer line that had to be dug up and replaced. (It was the original line from back in the 1950s, so not too surprising, but the timing was sure bad.) I did some pre-dig plant rescue, and got some things replanted in the post-dig clay. So that's the beginning of the restoration of the front flower bed.
Questions remain: will the dry well work as planned? What to do with the clay from the digging of the well? To be continued...
