Default looking for a decent plywood for a crawlspace "floor"

btw, (IMHO) a poured in place rat slab/mud mat will cause the same
drainage problems, if not more, than a simple poly vapor barrier...a
sump pit/pump would make sense for for a poured in place slab as
well... Just curious, where is the flood water coming in? From above
or below the crawl space floor?

His original post said the occasional hurricane floods it so one
presumes that's high water doing it.

The solid slab certainly has the same issue in spades as being no outlet
altho I note in another followup OP says he had ideas of washing it out
occasionally -- don't know where that water is to go but mayhaps there
is a drainage built in specifically for the issue, who knows?

If not, certainly putting in a sump is a possibility but on a 5-yr or
longer frequency probably just dealing with it at the time is sufficient
if there were a collection point.

As almost always, there's more unknown of a situation than is known...
