Stormwater runoff is a leading cause of water pollution in urban and suburban areas due to the high percentage of impervious surfaces such as roadways, parking lots, and rooftops. When it rains, stormwater washes over these surfaces, picking up sediment, oil and grease, heavy metals, bacteria, trash, and other pollutants from the urban landscape. School grounds present unique opportunities for onsite stormwater management. Public school systems or departments of education typically own or manage large amounts of public land in any given community. Impervious surfaces such as rooftops, basketball courts, bus loops, and parking areas often cover a large percentage of a school’s site. Additionally, school sites often have open or underutilized space. Land owned by the public school system, such as sports fields, may contribute pollutants, such as fertilizer, that discharge through stormwater runoff.
