Shademaster honey locust planted at top of retaining wall?

Veritaserum

We're in the process of doing our back yard. Our home is new construction so we've started completely from scratch. Because our lot slopes downhill in the back, we built a 4-ft. retaining wall made of rock that raises the ground to make the yard more flat. We're planning on putting a Shademaster Honey Locust (Gleditsia triacanthos) near the top of the retaining wall (~4ft. away), but want to make sure that it won't destroy the wall as the roots spread out. Here's my stab at giving you a visual:

(Tree would be planted in yard that is raised by the retaining wall.)

I've read that the Shademaster isn't a good tree for next to sidewalks and curbing, so does that mean we should choose a different specimen for the location near the rock wall? Thanks!

Gleditsia triacanthos untill recently was not a common tree around Melbourne but the ones I know don't seem to have huge root problems. The only old one I can think of is a 150 Gleditsia sinensis these are Chinese as the name suggests but it is in the city next to a major footpath and has never caused a problem.
What sort of rock wall? loose rocks or concreted? You could fill the yard with structural soil which would allow the roots to go down which should stop any problems.

Thanks for your response! It's a wall made of natural rocks, no mortar or cement.
