Sandra hired me to help her fight erosion under her new good neighbor fence. See, the soil was much higher on her side than her neighbor’s side – probably about 12″ – and her neighbor had a habit of overwatering their yard, causing the higher soil on Sandra’s side to wash under the fence. We put in some new boards at the bottom of the fence to make a tighter space between the bottom of the fence and the neighbor’s soil level, and then a few days later I came back and poured some concrete on Sandra’s side to help even more. She hasn’t had any erosion issues since!
