Raising retaining wall drainage

Hello Everyone,

Backyard - Album on Imgur

I am building a retaining wall that will be 1 level higher than in the first image of the album. My issue is as you can see the alley where I need to train water runoff is a lot higher than the bottom of my wall. I used all my paint skills to show my idea of using clay to raise the drain level and then I would use a tube with holes drilled into it to drain it into the alley but wanted others opinions on if this would work or if there are better solutions.

I can take more pictures or explain if necessary

Thanks in Advance.

Normally when building a retaining wall you put the drain tile (pipe) at the bottom of the wall and put gravel behind it. The purpose of the drainage is to relieve back pressure on the wall. If it's not at the bottom it will help some but not as much. That's probably why the wall you have is in the condition it is.
