Clean structural fill

[Mdntramble17]

I have a question in a geo report It states the engineer fill be free of organic material or less than 3% by volume. Is that typically referring to overall organics within the soil content as in microscopic organics that the naked eye doesn’t necessarily see, The contractor is placing fill, particularly within 1 foot of a rough subgrade On a building pad, where 100+ footings are going to be dug with these large stumps roots, etc. be acceptable? It’s in excess amounts, essentially just to avoid importing clean structural fill. Eventually, the concrete contractor will come excavate the footings and run into all this stuff and have a lot of unnecessary or affordable undercuts, correct?

Footing should rest on undisturbed soil. That material looks like it will settle a ton.
