Graphic Guide to Site Construction: Grading and Drainage Principles
Guidelines for preventing erosion and directing water away from the house
The development of a yard is not a simple thing. Even the most basic outdoor space with a deck, a fence, and a lawn require knowledge of materials, structure, drainage, soils, planting, and detailing for the weather. And more developed gardens that contain lighting, pathways, retaining walls, irrigation, and other complex components require deeper knowledge.
Whenever the shape of the land is altered, the movement of water is altered as well. Therefore, thinking about how water moves in and through a site prior to construction is critical in determining how the site plan is going to create new drainage patterns. In this excerpt from their book, Graphic Guide to Site Construction, authors Rob Thallon and Stan Jones outline the principles involved in erecting preventive erosion-control measures prior to construction, draining water away from the house, preserving existing grades around trees you wish to save and more.
