@blatham,
Bob and Diane's house had the concrete graded toward the back door. Mine's worse, and of course I saw it when I bought but expected to have the money to just break it out and fix, which was wrong of me; mine goes toward the back door three different ways. The overhead ill supported roofed crap hanging on by a nail or two over the cracked (don't get me going) concrete in the back of the house is the worst I've ever seen, and I've seen a lot, or so I thought. I've designed all that to LA codes for decades, so it's grieving to even look at. Cute little neighborhood, though.
I highly doubt anyone in the area ever took any engineering/land design, construction design courses. Not to mention planning.
On your bell beauties (I do like them), were there perf drain pipes to the outside - I am presuming so.
