With large gaps between the deck boards....sorry but I couldn't help it. I can't imagine living somewhere that the wind can blow 170mph. Canada has Florida sand. Come to think of it I did live in Ormond Beach for a few years....the wind came up and I found myself in Manitou Springs.

In our case, it puts you into ASCE-7 for design.
You can't prescriptively building anything in that wind zone. Being decks, I'll site the IRC. R301.2.1. Wind design region.
Truthfully though... We do not have complete research or standardized guidance available for deck structural design. Our culture didn't care until the last decade or so. There is much work to do still, from fire separation distance, to lateral bracing, to uplift. Hell... we don't even have universal agreement about what a deck, balcony, porch, patio, or sunroom even is.
I'm not very helpful on this one, am I.

Well, basically down here, all decks are engineered per ASCE-10 for now.
