Line all swale regardless of slope. In choosing linings, consider flow velocities, cost, aesthetics, desirability of infiltration, and maintenance. Use permeable lining materials to promote infiltration unless the slope is unstable or steep, in which case design an impermeable lining. Jan Johnsen, a landscape designer in Mount Kisco, New York, landscapes swales with a river rock lining and plants that thrive in moist conditions along the sides: evergreen ferns, sedges, winterberry, grasses, and Siberian and Louisiana irises. She also uses rugged prairie plants or other natives to fast-draining soil. Photo by Saxon Holt

A grass swale is defined as an earth channel typically lined with turfgrasses designed to capture, convey, and treat stormwater runoff from small drainage areas by a combination of physical, chemical, and biological processes (Barrett et al. 1998). Grass swales convey and treat stormwater primarily along highways and roads (Barrett et al. 1998.

BMP T7.30: Bioretention Cells, Swales, and Planter Boxes. Purpose.. Avoid the use of angular rock or quarry spalls and instead use round (river) rock if needed. Removing sediment from angular rock is difficult. Flow entrance should drop 2 to 3 inches from curb line and provide an area for settling and periodic removal of sediment and coarse.
