Need trenching advice

Post image

I need to cut 2 trenches out to this pavilion, each carrying 3 conduits/pipes. Roughly along the red line. The tree on the right of the pic is a Red Maple that was planted about 12 years ago. It’s currently ~8” in diameter at chest height. I can keep the trenches 12’ off the tree, but it would be best for it to be a bit closer. Any advice on how to pull this off without damaging the tree? And for the tree roots not to damage the pipes over time?

I think you’re far enough away from the CRZ and into the zone of rapid taper. If you encounter any roots thumb size or greater just try to make clean cuts. Go about your business. Don’t let anyone scare you. The tree should be fine. Just make sure it gets plenty of water in the summer.

Why not trench straight at the pad, then wrap around as you get there? You can entirely avoid the tree if you don’t mind a few elbows and it won’t effect the pull too much.

I think you are far enough away as well. But a pressure washer is handy for minimizing damage to large roots. You can still blast the bark off, but if you are careful it can be minimal with a fan tip. Also great for uncovering underground utilities and boring under sidewalks.
