Tad it is just a backyard decorative/retention pond that houses goldfish and whatever else makes it's way into the pond. It's kind of hard to talk with the owner Michel speaking broken english. So I'm doing some redearch on this type of pond since I've never dealt with this type before.
"Are they planning on back-filling soil over the liner to ensure a healthy Benthic layer is maintained?" What do you mean by this in simple terms? Scratch that I got ya. I was planning on letting it silt itself in over time to see what type of sediment ratio's end up in the pond.
