Does a retaining wall need to be stepped on a long sloping boundary?

Often, yes — on a long boundary with genuinely varying ground levels, stepping the wall down in sections (rather than one continuous sloped top) keeps each section’s height within a manageable, properly engineered range.

This is a design decision your engineer makes based on the actual fall across your site, balancing structural practicality against how the finished stepped wall looks and functions along the boundary.
