Downspout Pop-Up Location
I am working on burying my downspouts and I am not sure if I need to dig under the sidewalk to run downspout or if I can leave it. I'm running 4" PVC underground to a pop-up emitter. My options are:
1. Run it under sidewalk ( a lot of work and I'm worried about sidewalk sagging in the future.
2. Running it to middle of mulch bed (between the two yews).
3. Running it to the middle of the grassy patch just in front of the retaining wall.
