I need to build a little drainage ditch beside my patio to drain water away from the fence. There is only about 12 inches between the patio and the fence post. Is this area large enough to dig a small drainage ditch maybe 6 inches deep and 6 inches wide and feel with little stones? Ideally, how far away should it be from the patio to prevent it from collapsing into the ditch? Also, how far away from the fence post should it be?

If the little stones will prevent erosion the drain can go close to either. What we don't want to see is undercutting of the soil along the patio edge. For a long time grassy waterways have been used for water drainage. What will work to our satisfaction is often dictated by velocity.

What does undercutting of the soil along the patio edge mean?

Just my definition, but i see it as washing that soil away and leaving no support soil under the patio edge.

Hi,

Nice to see I'm not the only one with landscape drainage issues. For what I found to work for me and what you are describing. I used catch basin(s) for collecting water and ran a pipe away from the location to an area it could discharge and not cause problems.

Top of basin would be ground level. The fact that it is a solid basin, I don't think you'll have an erosion issue. ---\__/----.

I'm no artist.... But I think you get the idea.

Good Luck

Thank you. I have thought about this but my neighbour has cedar trees that are causing quite a mess on my property and I fear that this would block the top of the basin. I think I need to speak with them about whether they would remove these trees as they are at the side of their house in the back and really serve no purpose there. But I think that is actually a very good idea with this basin.

I understand your concern.

For Me... I think the walk outside to clear off the top of the basin serves 2 purposes... 1. Making sure it is clear, so that it does what I intended it to do. 2. Gives me a Smile and a reminder of a job well done.
