Be extra careful taking down those cottonwoods. They are weak ass trees and do really unpredictable things when taking em down. Alders aren’t much better but tend to be smaller.

I’d consider thinking of the wood chips as mulch for that area. You can just spread it around and it’ll decompose in a couple years and return a lot nutrients to the ground. It’s considered best practice in tree care. Just food for thought. You won’t have to pay for hauling away which is a big cost, but you’ll have the added work of spreading out the chips. It’s either your time or your money haha
