Hi friends. I'm making a duck wonderland edible foraging forest. I had a permaculture friend come help with ideas, and she encouraged me to do swales/berms. So I've dug them out, but it is quite impossible to get things level. There are old buried redwood stumps that I've been axing for days, lots of pipes to work around and under. It's not a large space, just a back yard, so I can't avoid this stuff. Also I rent. Also this project got way bigger than I wanted, and I love it, but I'm ready to be done, yesterday.
Aside from uneven water percolation into the soil, is there anything disastrous that's going to happen from unlevel swales? The most important thing to me is getting the water away from the house, so it goes downhill from the downspouts. Otherwise, unless I rent a grinder and a level, it's just not going to happen. Plant nice water loving plants near the low spots?
I have silty soil. Drains really well as long as it's moist. Light and powdery to dig in.
