    I wouldn't touch that without an engineer involved

    No, its called "universal slope block" designed for straight walls to maximum height of 4'. Nice curves eh, no cutting required:)

    Ive never seen it, but in the picture it does look like the back side of pisa II. Either way a hack definitely installed it!

    With hedge clippers.

    Are you going to answer my other questions?

    Interesting questions. A retaining wall, if one is possible, would be 4-5 ft tall near the top of the slope and would create a flat area ABOVE the wall at the backdoor of the house.
    - How to mow the flat area on top if grass is planted is a non-issue. The slope below the wall would continue to be natural wild vegetation hence no mowing req'd.
    - French drains would be installed in the gravel on the uphill side of the wall for drainage.

    Is a segmental concrete block wall the best for this situation and if so how would it be built. Such as ... How deep does the trench need to be below the surface? Do extra large and heavy blocks need to be used? If I find bedrock a foot below the surface do I stop or do I anchor rebar vertically into the rock and pour a solid concrete wall instead? Thanks

    An engineer is as an absolute necessity! Only an engineer can answer these questions for you. Only an engineer can "engineer" a wall for you to build that will hold up over time. There are many courses available for you to take in the meantime on how to build this wall. Don't be fooled. You are building an advanced wall with beginers skills. And no, beginers luck will not help you out on this one.
