Plan A is for a floor, Plan B is for closing the bottom.

Plan A Use double hdg hanges to hang double 2x10 untreated between the bottom 3 posts
treated between the middle posts.
We always build with 2x10 floor joists 16" on center with hangers between those beams. Cheating the size is up to you.
In order to do that you will have to dig alittle around the middle posts and reshape the fill a little as we don't want any fill sluffing down and pushing against this floor, best would be to have about 6" cleareance under the beam. The water shed I think will be hung from the house so I would be going for an elevation the would put your plywood floor under the door into that shed.
5/8 t&g plywood.

I would rmove the dirt under the shed too and later refill that with gravel so it won't retain water and push against the floor.

If I have misplaced it, it will be in the last place I look for it.

I think the 2x10s are a good suggestion to provide maximum strength and stability. As far as the closet, I am aniticipating making some modifications to it. I want keep that area enclosed and well insulated, but I can reconfigure the access into it as necessary to accomodate the floor.

I helped my nephew do something similar only not as much grade at his place and we took advantage of the area below the deck also. I think if it was mine and as long as I was closing it in I would include the deck area also in the plans.

On his we hung corrugated panels below the deck on an angle sloping away and into a gutter just inside the outer wall to carry the rain running thru the deck away. It worked pretty good for the type of storage area he wanted. Mowers, motorcycles and 4 wheelers etc.

You could actually have a double wall if you wanted the area under the house the dry space and the area under the deck the protected area. In my experience when you have a layer or two layers of unheated areas around a warm area each layer acts as a thermal zone keeping the heat in.

I like Neal’s plan A for framing also depends on how fancy you want to get with a floor in there. I could also see some 4x4 posts independent of the main framing kind of a floating deck under a house just to walk around on and store things.

One question did they ever have any trouble with the exposed drain lines in the winter?

Waiting on plan B also.
Neal’s plan B is kind of like the old saying “There are 10 types of people in the world. Those that understand binary and those that don’t.”

Right?

I don't do programming anymore but I can always use the practice in writing and debugging logical statements.

If you are going to modify the closet, turning the door to the inside, if possible, would add to the insulated value of the closet.

Don't forget to plan on access for wheeled tools/vehicles. Even something like a wheelbarrow benefits from not having to thump down steps.

Bud brings up a good point: are you planning a closed floor or something open like a "sub-deck"? I don't remember seeing any dimensions for floor space under the house vs. floor space under the deck: will they be separated?

A more basic question: I don't see an access path that leads down to the area. I think lugging stuff up & down that hill will become a drag awfully quick. so before you invest time, effort & money, consider how much you will use it.
