Hello. I found this very informative site while searching for answers. I have a "forest" as my kids call it on the side of my house with about four different pine trees. They have been growing healthy since before we moved in in 2005. In 2011 we had new neighbors move in next door. Their basement always floods when snow melts or it rains because they live down hill from all our neighbors. In April 2014, they built a burm of rocks and dirt on their property but then when it rained the water would flow through our property. I have pictures from August 2014 where our two eastern white pines were full and beautiful! However within a year the needles turned brown, fell off and never came back. The tow trees died. I know they were drowned From all the water we had from my neighbors burm. It washed soul away from their roots. Now three more trees are dying. One is a beautiful spruce. It is loosing needles and thinking out. It is looking weepy, the branches look wilted and kind of Browning gray. The other two trees are pines as well. They are turning brown. They have their down spouts running directly under our spruce now. How can I prove that they are drowning and have killed the two other trees so they can pay to have them removed and so they can remove the burm. I have consulted with a lawyer and our county. I was told by both that what they did by redirecting water to our house was illegal but the county can't do anything and the lawyer says I need to talk to my neighbors and I need to prove my trees were drowned. How can I prove it? Also what can I do to save my trees? I love my pines. I used to sit and just watch them on sunny days or I enjoyed the winter with the snow on them. I can't have anymore trees die. Thank you
