Once this property on top of South Mountain was cleared and the house construction completed, rainwater runoff drained through the middle of the backyard. Even though there were drainage retention ponds below, the area of the runoff continued to erode. We constructed a dry riverbed about 50 yards long to direct the water. In order to allow access to other areas of the property, we laid a bridge of large stone slabs, each weighing in excess of 1,000 pounds, leading to natural steps made of cedar logs from the property.
With waterfall areas and rain garden plantings along it, the riverbed has become an attractive feature instead of a problem area.
