Thank you everyone for your responses. She is the type that stays in her house and NEVER comes out. Many of the neighbors have never seen her and if they have it has been only once. In being her naighbor for 13 yrs I have only seen 1 person at her house. She drives straight into the garage, blinds are ALWAYS closed and it has been up to 100 degrees and her swamp cooler has yet to be serviced and run for this year. She must be hot as hell in her place. Yes it takes 2 to make an issue...I agree. I have told her I will remove the plants and all she did was yell and curse me out and say she will take everything from me and walked off. The wall like I said I received a permit for and there is a section because when I had the wall built the labors didn't listen to me and part of it encroaches on her utility easement by 3 inches. All of these were there for years with no issue until she has just flipped out. Now my posting was for anybody's knowledge was on if the plants can actually damage the foundation. I would say the non painted section on the foundation has lost maybe at worst case a 1/4 inch of sand that has come out.
