Neighboor flooding my backyard?
I finally moved to my first house last Jan, I mean townhouse, and realized that my backyard is flooded since last winter. I've noticed that the water comes from my east neighbor which impact me and my neighbor on my left side. Two houses from my east side has a french drain in their backyard that dumps the water on us.
From what I've noticed is that we don't have a shared swale with drain at the back but that neighbor solved his issue. Is legal what he's doing? How can I solve my flooded backyard problem?
