Stormwater Mitigation

Stormwater runoff includes rain, and water runoff from your lawns, rooftops, sidewalks, roadways, and other impervious surfaces. Stormwater runoff flows through our stormwater system of drains, pipes, and ditches – in some cases untreated - into our streams, rivers, and lakes. Stormwater carries with it pollution such as oil, chemicals, fertilizers, and other pollutants it collects along the way.
