This is one of my asshole neighbors. This guy lives on the left side of my house. He and his wife are older retirees, just like the Italian couple on the other side of my house. They have nothing else to do but work on their yards all day, every day.
This particular asshole dumps all his yard waste onto my property as shown in the photo set. Not the best photos I know, but I'll be getting a nicer camera soon with a zoom lens. The property line is about 10 feet behind where he dumps everything. He is aware of the property line as it's all marked with metal pipes sticking out of the ground. There's actually a black fence there behind him, but it doesn't show up in the photo.
The last 2 photos show him sweeping the sidewalk in front of his house, then dumping it on my property with a wheelbarrow. He has a big yard vacuum and a wood chipper. There's easily a few hundred pounds of stuff dumped there, all his grass clippings, leaves and sticks. The city picks up all this stuff for free, but I guess this asshole is too lazy to bag it.
