Best Management Practice: Armored Ditch

Armored drainage are rock-lined ditches. Ditches are designed to hold and transfer storm water. The rocks create a enough surface area to slow down the velocity of water within the ditch. Adding angular rock to a drainage feature will increase the longevity of the BMP . Velocity of water is what this BMP controls. Armored drainage is installed where ditches become steep enough to cause more erosion.
