Stepped, Plantable MSE Wall
There is a stepped, plantable mechanically stabilized earth (MSE) wall to be constructed from
approximately ST 44+05 to ST 63+88. The height of this wall will vary from about 10-30 feet
tall and it is planned to be 1,983 linear feet long. WFLHD will place topsoil along the entire
base of the wall, burying the first two to three steps and creating a 3:1 slope (H:V). RST will
place weed-free topsoil mixed with compost (1:1) over the remaining exposed wall to provide
a continuous slope and effectively eliminating the appearance of steps. Shrubs and small trees
will be randomly planted at the toe of the slope to provide vegetative screening, as well as
sparsely planted along the newly created slope. RST will hydroseed the entire area with
hydromulch, grass and forb seed, and tackifier. Irrigation will be an option item should the
RST specialist determine it necessary for the survival of the plants. See Table 4 for the suite of
potential restoration plants to be used on the plantable MSE wall.
