We had several discussions on the placement of these rocks on the yellow sand in this area. We knew we had to use some sort of "retaining device" and were hoping the large rocks would stay in place therefore keeping the smaller stuff in between them. Guess that is not happening. Even the excavation contractor had no good alternatives.
I do wonder if the rocks themselves will eventually settle into their place and we can somehow place more if we need to on top of them. Mind you this will take additional funding and maybe even another grant request. These items were discussed in the several on-site meetings but none of us believed we would see it so soon. Time to get to work on a solution it seems, let the ideas fly!
