Deck footing on a slope

[gtmeade]

I have a traditional style home with dormers and a covered porch/deck that runs across the entire front and wraps around both sides of the house. There is a fairly steep grade sloping away from the house and so the support posts for the porch and roof extend to about three feet below the level of the surface (floor) of the deck before they reach the concrete footings. The entire porch/deck including the floor and railings are constructed of pressure treated lumber. The support posts are just sitting on top of the footings which doesn't seem to be a problem except for one of the corner posts. This one is sitting on top of a 3 1/2 inch solid concrete block which is then sitting on top of the concrete footing. I.E the concrete block is acting as a shim. As I stated before, this footing is set into a fairly steep grade. I don't know if the footing has settled or if the builder just screwed up and put the footer too low and had to add the concrete block (shim). I believe that water erosion has made the problem worse and so I have taken steps to alleviate any further erosion by routing the downspout away from this area. But I would like to get rid of the concrete shim and in the process insure that no further erosion/settling/problems occur. I'm thinking that I can somehow support that corner of the porch and could then try to correct the problem. I'm wondering if I could just pour new concrete on top of the old footing up to a level where I can secure the post? I would like to take care of this preferably without disturbing the ground around the present footing. Or does anyone have any other suggestions? Thanks :?:

I think your solution sounds very viable. Supporting the floor above will probably be the worst part of it. Try to use a 4x4 across several of the floor joists and then a 4x4 from a 16x16 temporary concrete pad up to the 4x4 above. Hope that makes sense :D
