Hi my house is in the hills and my property is on an extreme slope of about 40 degrees. the slope is higher in the back, and that is where I have a problem. Along the back of the house there is a flat walkway just over a metre wide. Then there is a retaining wall that is about 1.5 metres high. I know that against the wall I should have a drain. But how do I make sure that any water that flows onto the walkway drains into the drain and not under the house? The house is a weatherboard cottage on stumps. how do I resolve the walkway to the back side of the house? Currently it is a mess of dirt and broken concrete and bricks. I also want to stop any leaf litter from going under the house.
