Rain <br />Gardens <br />DESIGNED <br />TO COLLECT <br />AND FILTER <br />RAINWATER <br />Traditionally, rainwater has been directed from our rooftops and side- <br />walks into storm sewers. On it's way to the road, this water picks up <br />pollutants such as oil from our cars and lawnmowers, fertilizer, and <br />grass clippings. Storm sewers are often allowed to empty directly into <br />our lakes and rivers, where the extra nutrients can cause algae blooms <br />and other pollutants can harm wildlife. These are the very same lakes <br />and streams we use for drinking water and recreation. <br />Rain gardens are depressional areas planted with a diverse mix <br />of native wildflowers and grasses. rainwater, from your roof, driveway, <br />or other impervious surfaces, collects in a shallow pool and slowly filters <br />into the ground instead of into storm sewers. There are many benefits <br />to rain gardens including: <br />• Stormwater retention reduces runoff of pollutants and nutrients into our <br />lakes and streams. Reduced run-off into sewers can help with flooding <br />problems as well. <br />• Deep-rooted native plants stabilize soil to prevent erosion during large <br />storm events. <br />• Diverse plantings with many species are more resistant to drought, <br />flood, insects and disease than a single type or low diversity planting. <br />• Once established, on -going maintenance is usually very minimal. <br />RAIN <br />GARDEN <br />4 <br />
