On a related note. I asked what you guys spec for exterior plywood decks and got 2 responses.
"This email is being sent to you in response to your inquiry regarding the need for pressure preservative treated plywood in outdoor decking for pedestrian and vehicle parking structures. As noted in the attached documents if the plywood is protected from moisture preservatives are not required. However, should the moisture protection fail the use of pressure preservative treated plywood will protect the structure from decay."
Well Duh.

and Andrew's suggestion of Marine Grade ply--better quality core but not decay resistant.

Anybody else have something?

Steel is not that expensive and cheaper than repairs or worst case failures. Of course it is no substitute for good water management practices, but it's a good belt and suspenders approach.

Maybe now things will start to happen, at least in California:
