I have serious doubts that anything will be "wrong" with the dry stack area. This really is more or less a formality of having a certified engineer interpret the data from the core samples and report the nature of the substrata. I'm sure that ground water and permeability will also be considered (if the haven't already), along with the natural drainage channels from the site.
The DRMS thinks this is a big deal, and for safety and liability sake it is. But as you have already said, ficoce, there probably won't be much construction required, save a bit of grading.
So, light the campfires and get out the marshmallows. All we can do is wait, stay calm, and not let our imaginations get the better of us. Things are moving along, and in the right direction.
Pass me a marshmallow, please?

I just hang out here for the fun of it, that
doesn't mean I'm smart.
