because now my yard is much shorter. The neighbor received a lot of fill from local contractors. When I asked the contractors for fill, they said my property was further away (less than 1/2 a mile) and the neighbors property was closer. So, their property is much higher than it was, and my back yard always floods. I have no proof, but it is obvious they received so much fill. Can I legally do anything? It has been happening going on about 3 years now. My basement also floods now. It did a little before, but much more now in the past 2 years.
