what to do with the french drain behind a retaining wall
so I'm building a short retaining wall, ~2 feet max, probably more like a foot 'n a half. it's going to be slopped and it's just to deal with a drop off around a corner of my house where a downspout is, I've run the downspout into a buried line so it puts out elsewhere now so it's no longer a problem. For the retaining wall, I know it'd be smart/best to put in a french drain so that water weight doesn't build up behind the wall, but what do I need to do with the end of the drain? the stone wall is going to taper to start and taper to begin, so do I need to just run the french drain into the ground with the wall and it will 'cause the water to at least not be held behind the wall or do I need to find a way to vent it out? I've seen a few directions that mention the necessity for a french drain but few seem to deal with what to do with the french drain at the end of the wall. I'd like to avoid having it be evident as that would negate the effort to hide the downspout.
thanks for the help
