Especially in dry climates, but also in wet ones, we see drainage management as an act of finding opportunities to exploit. Our approach is to direct stormwater to the right places in landscapes and to put runoff water, a mostly neglected resource, to beneficial use. In this way, we increase the value of a given property as we reduce the costs of watering and maintenance. On most sites, proper drainage can be achieved by grading (or sloping) the property effectively at one-eighth of an inch per foot. (See also “Erosion Control” and “Passive Water Harvesting” in this portfolio.)
