Description

FIG. 1 is a fragmented front perspective view of a retaining wall facade of my new design with earth in broken lines to show environment, the pattern of the retaining wall facade being repetitive throughout its length;

FIG. 2 is a front elevational view of the retaining wall facade of FIG. 1;

FIG. 3 is a front elevational view similar to FIG. 2, but showing vegetation in broken lines between adjacent blocks;

FIG. 4 is a top plan view of the retaining wall facade of FIG. 1; and,

FIG. 5 is a top plan view of a second embodiment of a retaining wall facade showing my new design.

The only difference between this embodiment and the embodiment shown in FIG. 1, is that the wall is vertical rather than sloped.
