We got 13-14” according to reports.
Our deck is high like yours and will carry the weight. We built it to exceed code.
People with decks should also be aware that it could, rather than collapse, also pull itself off the house. It’s good to check it out if not sure.

We've been talking about having the deck fortified and the surface replaced with "Trex" since last summer. I hope we didn't wait too long.
You were wise to take that extra step.
