When assessing drainage structures in particular, I frequently see just a couple of stones set intentionally around the outlet. I assume there is some protective benefit and sometimes they appear to keep the bank intact, but I’m not sure if they qualify as “dry-fit” or deserve a condition rating. In my opinion, some additional guidance would be helpful.

Did anyone get an answer for this one? I am also interested in seeing best classification for this assessment. Cheers. -Scott
