I have a fairly small backyard and want to push the retaining wall on the side back by 6' to get some extra space where we can put a bbq and have some dining space.
My question is.... How do we push it back? Is it safe? Do we need an engineer to look at it? How much space will we get as the total space from the front wall to the back is 10'? How much do you think the cost would be? We are in southern CA
