I'm slightly concerned about the deck skirting on the elevated side and back decks, since it clearly violates the wood/ground contact rules. It's just 1/4" plywood and I don't care too much if it rots out and needs to be replaced periodically, but if it's a significant termite issue then I'd like to consider some alternative design.
To the extent reasonable I'd like to cat and rodent-proof it, because the deck crawlspaces and the house crawlspace are contiguous. (You can see some tunneling has been going on to the left of the steps.)
So what are the usual (or even unusual) approaches to this issue? I can think of a few home-brew concepts but there must be some standard ways of dealing with it.
