Thank you sir this is very helpful and what I was looking for. Much appreciatedThe code does address what you are doing and it is load bearing. Since you stated your crawl space wall is 7 ft tall I would question the height of your column. As you can see in the codes below a solid grouted masonry pier will allow you to be much taller than an un-grouted pier and I think from your post grouting the piers will be required. Personally I would grout all the masonry in a high seismic zone.
