I like the idea. I think a retaining wall like this is a good way to tighten or neaten up a situation like this. I would leave as little as an inch between the bottom of the fence and the concrete, it’s enough to breathe and to tight for a cat. Put wood preservative on as much of the fence post as you can get at, wrap the post in copper 1 inch above and 6 inches below the concrete level, perhaps let into the post with a reglet. This will last as long or longer than the post would in the ground.
Your mention of heaving concerns me. Where are you? Here on the Pacific, the ground doesn’t freeze significantly. If you put the wall on well drained and undisturbed soil, heaving shouldn’t be a problem in any climate.
An engineer would probably have you put a wide footing under the wall, at least on the back-filled side, especially if this side will be subject to any traffic compaction.
Don’t forget the steel, something like two or three half inch bars in the footing, with hooked verticals 16 inches on center, and a few horizontals.

I need some suggestions for a retaining wall. I have a fenced yard and the back left corner slopes down about 2 ft from grade for about 35 ft. I will be putting in a slab foundation for a garage in this area. I want to bring the grade up to level and back fill around the slab so I need to build a retaining wall under the fence. I built the fence 2 yrs ago to accomodate this. This portion of the fence doesn't follow grade. I was thinking of pouring a concrete wall under the fence with about 2 to 3 in clearance from the bottom of the fence. The concrete would be poured around the fence posts and they would act as footings since they are cemented in 4ft below grade. Would I have any problems with heaving? Is there a better way of doing this? I don't care what it will look like because it won't be visible. Take a look at the sketch to get an idea. This is a view looking at the fence from inside the yard. Thanks
*Gaby,Exposed wood posts set in concrete will rot. Cut your existing fence off, about an inch above the top of proposed retaining wall. Pour the retaining wall with steel anchors in place to bolt your fence posts.Dave
