Hey /diy/ I could use some ingenuity.
There's a decently steep slope around the back of my parents house that they want to stabilize/terrace so as to have a nice little walkup patio for them and all their old friends.
Considering the steepness of the hill and how much rain the area gets (a lot) and the fact that the soil is primarily clay with some silt, I'm a little nervous about destabilization and sliding.
I talked to an engineer friend who suggested pic related, geogrids. Layer them between the dirt and they help stabilize it and make it a hell of a lot stronger and less likely to shear.
Now, here's my dilemma. Traditionally you bring in a backhoe/other machinery to dig things out, lay these down, and tamp the earth back when you're done. The placement of the hill and cost of renting machinery, however, make this difficult.
So here's my question: is there any way for me to insert these sideways into the hill about 6 feet or so, or at least mitigate the amount of digging I have to do? I figured I might as well ask you guys before I went ahead and committed to anything, but I'm not terribly optimistic.

easiest solution is just to plant it. Look up plants for erosion control or slope stabilization. Anything else is going to require permitting/money. The tallest retaining wall you can build in most areas is 3ft high, and its going to cost exponentially more once the wall gets higher than that. If you want to terrace and maintain code it needs to be done like pic related, but its going to require digging and back filling. Often times taller walls also require railings so people dont fall but idk if that even applies with your terrace idea.
Geogrids are used at specific slope angles with diff soil types. Engineered solutions like that arnt a one size fits all solution.

also this is (conceptually at least) how you want to cut and fill on a slope to create a terrace

I like block retaining wall myself. When I was a kid my dad built one with railroad ties. Lasted quite a while but probably not permanent.

hire some immigrants to dig.
