A levee barrier panel to form a levee retaining wall has a top and a bottom and a plurality of apertures extending from the top to the bottom of the levee barrier panel. A cutter tool extends through to the bottom of each panel to transform the levee composition into a slush whereby a vacuum removably attached to the aperture sucks out the slush thereby forming an opening in the levee. The levee barrier panel is then lowered into the opening.
