That is for large areas of farmland, but the general principles still apply. A mole drain wouldn't be much use because there's no room to pull it, but if you put 3" perforated corrugated pipe in a silt sleeve at the bottom of the drain ditch (holes DOWN) and cover it with gravel, it should drain that right out. We did this in our back yard and it really, really helped. A formerly boggy spot behind the deck is now clean and dry (the water is now draining to the opposite side of the lawn and THAT is now soggy, but that's a different problem!)
I’ve thought a lot about that, a shallow french drain along the outside wall, and yes, it could drain right into the drainage ditch.
When we build our own place, a lot of investment will be in putting in good drainage.
