What is the name of your state? California. The back of the next door neighbors lot slide from the all the rain So Cal is having and caused 1/2 of my back lot to slide. The lot is empty and no plants or reinforcement has been done on the part that gave way. My lot has thick ivy and trees and is reinforced on 1/2 of the back wall, the only part that did not give way. I have a geo report stating that that lot is not graded to current codes and according to the report, it could become unstable if it became saturated. My lot would have been fine if his did not slide taking mine with it, So far it has ruined a section of my fence and mud is coming over my back retaining wall and the landscaping up above is in jeopardy. Who is responsible for fixing this mess the estimate I got today before more rain started was over $10,000. What should I do? Contact the city? Ower of the land is not returning my calls. Any ideas?
