I fail to see how storm runoff is "harrassment." It's pretty obvious that the runoff is right where it's expected - there's a storm drain grate in the pictures. It looks like someone doesn't want their neighbor's rain to affect their property.
This tells me something too: "others in the neighborhood." When someone thinks that all of their neighbors are out to get them, they just might be
The harassing behavior from those involved has been going on for a very long time and there are so many witnesses, documents, and pictures. Neighbor's coming in and out on the private dirt road at excessive speed, laying on the horn while proceeding around the inside corner on both sides of the property at all hours of the day and night. Those involved even have their family members and visitors harassing too.
The metal grate you see in the picture was put there by Brian Jones on 8/3/2013, after he and other's dug a hole in the pipe for all the road run-off to run towards he's neighbor's property. That pipe was purchased and installed by the property owner with the intent to control the road run-off and to protect their property from further damages, which did not work.
The original development drainage ditch and drain pipe for the road and other properties storm run-off was covered by the property owner Diane Henderson, and she planted trees in the roadway where the ditch and drain pipe use to be. The uncontrolled run-off continues running across her neighbor's property causing ongoing damages while those who pass by watch, laugh, and take pictures.
Surely these neighbors wouldn't want to be harassed and incur damages to their property as they have been doing to another. But, maybe they would like to be treated the same as they have been doing themselves, not caring about anyone and continues with their nasty vindictive behavior and actions.
