Best Management Practice Fact Sheet 3: Grass Channels

426-122 (BSE-271P) This fact sheet is one of a 15-part series on urban stormwater management practices. Please refer to definitions in the glossary at the end of this fact sheet. Glossary terms are italicized on first mention in the text. For a comprehensive list, see Virginia Cooperative Extension (VCE) publication 426-119, “Urban Stormwater: Terms and Definitions.” In typical urban drainage systems, runoff is conveyed to storm drains and underground pipe networks; this practice speeds up the arrival of the peak; causing stream erosion, flooding, and potential water quality issues downstream. This fact sheet describes a low impact development practice known as grass channels. Storm drain piping is replaced by grass channels to move water from one point to another. Water is slowed down, providing some infiltration and improving water quality. 8.5 x 11, DS, color, 4 pages, 24#, single staple upper left
