Drainage Issues/Retaining Walls

Another project almost done. Bad drainage behind the retaining wall built out of railroad ties decades ago (slightly shifting foundation of house). We will build a cinderblock fence in front of the railroad ties. Until then we had the idea to use some of the old gutters that were just taken down and make a run-off drain. Lots of digging, hacksawing some iron spikes, putting the gutters in place and then putting dirt back around the gutters. The length is over 30 feet. Note the spikes sticking out from one of the ties.

Oh, did I mention it's almost 90F here today and this is the South. I'm accustomed to CA heat, I still haven't adapted yet to the southern humidity.

 trench dug behind the railroad ties, note the down slope of the railroad ties and ground, made it much easier to put in a drainage system.

note the spikes, hacksaw and sledge hammer
