Quarantine project - short retaining wall on a sloped garden

Good day - So we have this sloped garden that is difficult to maintain so we're going to rip much of it out and stary all over. One thing we want to do is to flatten the slope a bit so we're going to put in a retaining wall at the bottom. We need a permit if we go over 2' height of the wall so we'll probably be doing this 18-23'5" (using 4" high blocks). First question (of probably many!) is for a wall this high how deep do you think the trench should be? I'll be using crushed or pea gravel as a base - perhaps an inch deep tamped down. So for a relatively short wall, do I need to have the first course at ground level or can it partially be exposed?
Thanks!

Permit for a retaining wall?

You want at least 6-8" deep footing with sharp (do not ever use pea gravel) base compacted every 2".

The sharp gravel/limestone, locks tight when compacted giving a solid base. Pea gravel can not be compacted!
