Water pouring into our backyard
There is a new construction has just started behind our house. They just finished cleaning up the trees and leveled the ground. Last week with the heavy rain, with the elevation of their house compared to ours, tons of water with fresh dirt poured into our backyard and caused our basement flooded and the sump pump is still going off frequently. We have been in this our for 26 years and twice our basement had flooded with heavy rain but never had the water pouring into our yard like a small creek.
My question is that what can we do about this? Unless they change their grading my house will be in deep trouble every time it rains. Can the HOA help me to talk to the builder?
If this is the wrong place to ask this question, please provide some guidance. Many thanks.
