Only thirty percent of the earth’s surface is covered by land. When gravity pulls precipitation to the earth’s surface, water is either absorbed into the ground where it falls, or it flows across land as a liability. Water moving across the surface of the earth, can do much damage. It erodes soils, dissolves solids, carries pollutants, undermines foundations, and accumulates to flood low lying landscapes. All across the nation, in efforts to infiltrate water where it falls, regulations are being set into place to tax properties that shed water downstream. By designing landscapes to work with ecological functions, however, surface features such as roofs and pavements can be employed to make use of water as a resource. We present the following solutions.
