Neighbor Issues

My neighbor has about 6 very tall coconut trees in his property which lean over the property line into my lot. They are on the backside of his property which is not developed by him, but lean into mine directly over my porch and where I park my cars. I can't even park where I would like to on my property because of the occasional falling coconut, I see them on the ground in the mornings and wouldn't want to be directly under a 10lb coconut when it falls froim over 40ft up. They also hit my tin roof on my porch and dent it. I've talked to him and he is very rude and doesn't care that they hang into my yard. What can I do to get them removed? He won't listen to me and says that since they are planted on his property it is not my problem, even though they have all grown on an angle into my space.

I'm sorry, I posted this in the wrong forum, please delete.
