There are special interlocking Concrete landscape units designed for your application. I suggest you focus your research in that direction.
One of the main advantages of using concrete landscape wall units is they are typically mortar free and self weeping. Last thing you want is for water or moisture to build up behind a wall like that. The horizontal pressure and change in coefficient of friction in the soil is a double strike. Add rain and strike three.

DITTO..
For a roughly 3 foot high wall chances are you will need a PERMIT..which will tell you what size block , how deep and how wide your footing has to be, how much re bar, and that you have to fill all the block cells with concrete. So what you are in a sense building is a wall made of cement.
Building a retaining wall otherwise with CB is a disaster waiting to happen.
On my last house I built 30 ft of 6 ft high, 105 ft of 5 ft high and 240 ft of 3.5 ft high CB retaining wall. If I recall the footing alone required 35 yards of concrete. All of it needed engineering details.. One side of the pool itself acted as a retaining wall. The re bar in the pool was set 4 inches on center, required 55 yards of Gunite and was 18 inches thick. So I know a thing or two about retaining walls, building pools, landscaping and construction.
As far as subing a custom home I could do it but would need quite a bit of help the first coupla times through.
BTW U can call me Maurice as I even know interior design. I was just too fking cheap to higher a decorator. So I learned.
