My neighbor built a play area lined with timbers and filled with mulch that oozes water into my yard-very wet?

Question

it butts up to my fence and they also turned their downspout towards my yard as well. Any suggestions on keeping their water out ? and they also just put up their pool for the summer right next to all of this.

Answer 1

woodtick makes a good point, but if you and your neighbor are on good terms, talk about spliting the cost on a "french drain"

Answer 2

It is illegal in most municipalities to divert water from your lot into a neighbor's lot, unless there is a means there to collect and disperse it.  Try talking to the neighbor about the situation.  IF that doesn't work, contact the building inspector in your area.  They will have on file all plots that show drainage easements.  If the neighbor is violating the plot, they will have to fix it or pay when you have it fixed.  Good luck.
