I live in a new construction home. I have been in the home for over a year. On the one side of me they finally started to build a home. Well when I got home on Friday I found a 4x4 cut in my front lawn, and the sod pulled back. I went over to the construction guys and they told me that they had to locate a sewer on my property so that they could tie it into the new house. I have a twenty foot easement in my front yard with a sewer running though it, but they now want to put in a man hole. I called the city and they said that yes there was supposed to be a man hole put in when I built the house but they failed to do it. They want to come out today and survey it. My question is can any builder come over I my property and just start digging? I understand that I have an easement but shouldn't they ask me or tell me so that I can minimize destruction of my property. I told them that I have a sprinkler system and and expressed that I dont want my property destroyed. They told me that they can do whatever they want without permission..
