Neighbours Sump Flooding Yard

I live in a new subdivision. All of us have built bi-levels except for the neighbour that I share the back corner of my yard with. He is in a low spot and built a bungalow so all of the water drains to him from the properties around him. His sump hose is directed to the back of his house and drains to my yard and the empty lot beside me. Poor guy is getting a lot of water, I can literally see it gushing out of his sump hose. I was wondering if you had any suggestions as to help prevent that corner from flooding. Before his sump was discharging out the back we never had any water issues and I'm trying to get a fence built but it is too soft back there to drill post holes. Any suggestions that you have would be appreciated. Here is a couple photos to try and explain. Thanks!!

 

Tell him to stop pumping it into your yard.

 

I assume he is pumping the water out onto his yard and is collecting in the lowest point since water does not know where the property lines are. The only direct it knows is down to the lowest point,

You could build a barrier (soil, rock or concrete) to keep it away from your property. Then it will be diverted to another property that is lower than the top of your barrier until they build a higher barrier.

It sounds like a poorly designed site drainage plan by the developer.

There are normally rules about discharging water or directing water via landscaping or grading so that it floods your neighbor.

I understand your sympathy towards him...but those were the choices he made. He needs to direct the water so that it drains to an area that will not impact anyone else.

If it's a new sub-division...I'd assume there's some storm drainage?
