Who's responsible and what's the etiquette?
About three years ago, our neighbors widened their driveway (alot) and now its literally up to the property line. Since its intallation, we've had problems with water in the basement on that side of the house. During rainy and stormy days (like yesterday) I was able to watch as the slope of the driveway brings all their water from he giant driveway and back patio towards our house. To complicate matters, the owners who put in the driveway have since moved and the new owners are first-time homeowners. The previous owner had discussed with DH about addressing the problem together, but moved before anything was done.
1st ? - Would a French drain be the best solution? Can wedo or should we have a professional do? Any other ideas for problem solving?
2nd ? - Do we ask for their assistance? Technically, it would be on both our properties (maybe mostly on theirs). Can we just go ahead and do it or do we need approval (written or otherwise) to access their property?
