Michel,
There used to be a publication called "Architectural Graphics Standards" that had a whole series of fully detailed cantilevered retaining wall sections (I think it was Architectural Graphic Standards; I only have the retaining wall pages). This would be a good place to start.
Regards,

My clients share a property line - one on the down slope who would like to minimize the size of the toe and the other up slope who would like to minimize the heel / size of the excavation. What to do??-Michel
