Whats the "policy" you use when you have the neighbor concerned about the possible water comming from or preventing their water from exiting there property when grading lots? I had one customer that that was getting all the run-off from his neighbors yard. This customer installed a drainage system to carry water under his own property, then called me to bring in about 30 yard of dirt and grade. Neighbor was concerned and started to question me about it. How do you guys handle this and should I have permits for this stuff? I live in a small community and dont do a whole lot of this type of work.
