A new neighbor and her builder are totally rebuilding a house on the 29' wide non-conforming lot next to mine. The builder politely requested copies of our, and the further adjoining neighbor's, survey maps, so he would not have to pay to have one done before starting work. Why one wasn't done in May when the title changed hands is a mystery to us. Now the builder has removed our own, and the adjoining neighbor's survey markers, and is proceeding to encroach, having already bulldozed 2' of the adjoining neighbor's land, and says he is removing a 100 year old paved public path immediately across our own common boundary on the new neighbor's side. He says Ohara township never makes him put anything back once it's gone! The other adjoining neighbor is currently swept up in burying her mother, settling the mother's estate, and grieving, and has specifically asked us to learn what we can, and advise her how we all should proceed. Do we go to Ohara Township first? Where do we start, to stop these people?
