Channel drains are used to capture, divert & direct storm water runoff. Also known as: Wash,
River Run, Arroyo.
Channel drains can be constructed using Rip rap or River rock.
Rip rap is a term to describe a type of rock, usually granite or other crushed rock to a size of 6" to 12",
preferably flat. Rip rap can sometimes occur naturally on the property or purchased from a Landscape
materials supplier. Rip rap channels look best in natural settings where the landscape is mostly native.
River rock are round smooth stones typically grey & red in color. River
rock channels are commonly used in landscapes to control water flow & also enhance the landscape by giving it a natural
feel. River rock channels look good in tropical settings as well as desert.
With either Rip rap or river rock it is necessary to lay down an erosion control fabric. This prevents the channel
rocks from being undermined & helps keep the soil seperated from the rock. Erosion control fabric basically keeps the
channel in place.
