Thanks Jim. I had thought about that too, but I didn't like the idea of putting wood down into the ground because of rot. I wonder how the Spanish-built buildings lasted so long with the wood in the ground?!!! What I have read, indicates you can expect the treated wood post to last for only 100 years.

I am wondering if I added bracing from the column to the stem wall would do the trick. Can't remember what that type of brace is called?
