Drainage Solution (Diagram Included)

This is a view of my property line and the adjacent neighbor's property which is elevated 6ft. above my property. The neighbor installed a massive retaining wall almost the full length of the property which stops and soaks up a good amount of their water from above. However, their driveway still shoots quite a bit of water in heavy rains which runs down in front of their wall and some into my foundation. I removed a ton of ivy that was engulfing my foundation wall and regraded with a swale and trench for a french drain. Before i cover up my french drain i want to double-check that i approached this ok. I also want to outlet the french drain into my existing downspout lines that are buried and tie to the storm sewer at the other end of my property. Thanks for your advice!

It sounds like it will work to me. Did you use a filter fabric to keep the soil out of the stone?

It is always a dangerous situation when you connect a foundation drain tile and gutter sytem together.

The drain tie system picks up water and delivers it much slower the the gutters, Because of this, in a heavy rain and or back-up from the storm system, water can flow backwards to the drain tile/french drain. This backflow can plug a drain tile system or plug a french drain system.

I have no idea about the elevations and lengths you are talking about in the post.

Hi Appleman01:

The theory sounds OK unless the flow from your neighbor would overwhelm your system.

What would happen to the water if, in the future, your drainage system were to get clogged? Would your property be flooded?

The easier and more permanent solution is for your neighbor to correct the damage he is causing. I would think that you may have a claim against him if he isn't willing to resolve the problem.
