3 <br />STORMWATER RUNOFF MANAGEMENT <br />Much of the rainwater that falls in <br />urban areas, runs off rooftops and <br />driveways to streets; through the <br />storm sewers; and finally, to lakes, <br />streams, or rivers without filtration <br />or treatment. As it travels, water <br />picks up a variety of pollutants, <br />including sediment. The goal of <br />runoff management is to keep <br />excess water and pollutants from <br />reaching the storm drains in your <br />neighborhood streets. <br />KEEP WATER IN YOUR YARD <br />Increase the opportunity for water to soak in or infiltrate into your soil. <br />Many of our flooding and erosion problems exist because we move <br />water too quickly off of our landscape. Water that once took days <br />to filter through to the nearest lake, wetland or stream, has been <br />channeled and moved off the landscape quickly through a series of <br />impervious surfaces and pipes. <br />TO DO/Divert roof top water runoff by: <br />• Moving or extending the downspouts to flow onto a vegetated area. <br />• Creating a rainwater garden. (see Rain Gardens, pg 19) <br />• Creating a water retention area with a shallow, grass -covered turf <br />depression in the lawn. <br />• Stationing a rain barrel at the end of one or more shortened down- <br />spouts. (see Rain Barrels, pg 36) <br />
