If you want to move the bags after 200ish hours and they have been in the sun they may fail. But if you just plan on keeping them there then you should be great!

If too identical twins were building a wall , one shoveling those bags full and one dry stacking urbanite, my money would be on the dry stacker finishing first. This assumes that a big stack of the stuff is on site, which is a bit of an assumtion, I know. I'm sure the bags will work. In fact they are probably far more than is required to hold back your dirt. I like to avoid driving tacks with a sledge hammer.

This one illustrates the space used by each system as seen inside a greenhouse 10 ft wide with walls 6 ft high and 8 ft at the peak. Notice that with the urbanite we can easily alter the width of the walkway. The height of the bench can also be adjusted at will.
At 4 ft high with the bags, with the thickness of the bench and drainage space, the soil in the grow bed would be 5 ft from the floor.
Drippings from the bench can flow to the fill below in the bottom drawing since there is an air space. With the bags,in the upper drawing, some other method of drainage must be arranged.

The mesh gives you something for a plaster. If you keep the retaining wall short, you can use small posts (1/2 rebar). Stair step the retaining walls up the slope.
Backfill with dirt and tamp as you go. Lots of fabrics could work. Call your area billboard companies.
