Very informative! We're just in the process of having our 37 year old deck replaced with a new one. Lots of upkeep over the years, but it was time. Pretty incredible to see the differences in code here in Minnesota from 1986 to today. Our new deck is being installed with helical piles. I noticed that you didn't mention them. The ones that were installed go down 12', to some really solid soil. The first several feet in our yard are pretty spongy, and the original footing which went down 3-4 feet sunk a bit over the years. The helical piles supposedly have no movement or settling. Interesting process to watch as they're being installed.
