Math question for any engineers out here
I’m in the process of building a parking pad in this spot. I ran a string line to measure my retaining wall height. If I have the line 3 feet above the ground and check the line for level, it is still...

I'm no engineer, but I assume you're going to trench down and pour footings for the retaining wall?
As for the final slope, it's good to have some pitch to it for drainage, and then you can use blocks for final leveling if you need to.
No footings are required if the OP does the correct type of retaining wall. A Versalock (or similar system) wall can bear on a compacted gravel footer, and uses a tieback mesh (Geogrid) in layers for stability. You could go 50+ ft high. They spec you can go 8' high without the geogrid but I would do at least a layer every 32".
9.50 inches fall over 4' equals 71.25 fall over 30' (5'- 11 1/4"). The OP gets it correct and see PastorCharlies post above. Some of the other posts look like an engineering report for building a nuclear reactor, and read like War and Peace, but I would expect nothing less here. It's not that complicated but neither is towing a trailer or airing up a tire LOL.
