I closed on my new home in the Shilo farm subdivision in Lyman SC on 12/30/2019. Within two weeks we had several days or rain and mu back yard held several inches of water over a large percentage of the side and back yards. I notated this concern before closing and was assured it would be taken care of. Two weeks after closing instead of fixing this properly the builder put a 1 foot by 8 inch trench across my yard draining the water to the neighbors yard. I complained about the safety of this and the ability to maintain it as I have two young daughters that live with me. All that was done then was to expand the trench and now my entire yard slopes toward my house and to the left neighbors. My yard is not usable in its current condition and has not been surveyed since may of 2018 according to my title insurance, yet DR Horton is claiming that it meets all drainage requirements, plot plans, and grading requirements of the county and build plans. This is not right, as I was sold a plot of land that was flat and graded properly, and then after closing be treated like being a current customer does not matter to them. It has been over a week since I have filed a warranty claim and emailed the man in charge of land development for DR Horton in Greenville with no response. To make matters worse the same size plot of land had the same house on it 3 doors down from me and their yard is graded properly and has no drainage problems. I just want to have my yard comply with community standards, and to be usable. Yard must be re-graded and sloped properly to allow proper drainage.
