Properly positioning a retaining wall is important because you want it to be stable. Here are the two main ways to do this:

 Set the retaining wall well away (say, several feet, or a meter, or more) from the original hillside, and then fill in behind the wall. When you install the wall, you still create a base and backfill with some gravel, but the rest of the gap between the original hillside and your wall will require extra soil to be brought in.

 Set the retaining wall close to the top of the original hillside. In this case, you need far less extra soil. In fact, you may be able to simply reuse the soil removed from the base of the hill, shoveling it in near the top of the wall.
