We run a food pantry and it is accessed by pulling down the ally. My neighbor complained that the cars that go past his property have cut off the edge of his yard making it hard to mow. Other vehicles travel through the ally also. I pointed out that when it rains the water flows very quickly past his property because the ally naturally leans into his yard and the ally drops of fast past him. He says it's my problem and I need to fix it. I have used orange cones every time we give out food which is once a month. I have put over $3000 of rock on the ally in the past 5 years. What do I do?
