I built a garage a year ago and extended our driveway to the new building. We used driveway stone because we wanted to use it for a while before paving over. I would now like to pave over the area but during the last year have noticed that on the stoned area adjacent to my neighbors property a substantial puddle forms during wet periods and remains for several days. The area is very flat and there doesn't appear to be a way to divert water off of my property and I don't want to add to my neighbors already soggy backyard (he has the low spot in the area. What are my options and/or who would could I contact that would give me sound advice how to proceed. I hesitate to listen to paving contractors for fear that their judgement might be biased. Thanks for any input.
