I have a fence that separates my land from my neighbors and I'd like to figure out how to prevent dirt from washing onto my land from the 2" gap under the fence. It's a painted wood fence with horizontal wood.
There is a slight slope to my neighbor's yard and my side of the fence has a wide brick walkway that is about 6-10 inches away from the fence. The opposite side of the walkway features a short concrete hip wall with french drains running along the edge. Those drains get clogged by the dirt that comes from my neighbors yard when we get a good amount of rainfall and therefor it can create a small lake that is not fun to walk through.
This fence is a very sensitive issue with my neighbor since the previous owner on our house installed it to replace a much shorter fence. The taller fence cut off much of my neighbor's view of a pond that is nearby. We love the fence since it makes it so we don't see much of the neighbors ugly yard and gives us privacy. So, I'm looking for a solution that might allow water to flow, but dramatically limit the amount of soil moving while at the same time not creating too much notice on my neighbor's part.
A contractor wanted to remove the fence, install a retaining wall with filter fabric behind it and then re-install the fence. That would a) be too expensive and b) cause way too much disruption with my neighbor. Is there something I can install either on my side of the fence in the 6-10" gap between it and brick walkway, or something I can slip onto the neighbor's side that would not be overly noticeable.
Below are the original architectural plans where I added color: Black=Fence, Red=Brick Walkway, Yellow=hip wall
