Help reduce non-point source pollution, contaminants carried by storm water into streams and lakes, which harm salmon and other aquatic life by planting a rain garden. The idea is to plant a garden that will capture and filter rain runoff before it flows into our local waterways. Read about how to design a rain garden and what plants work best in the March/April 2003 issue of the American Gardener Magazine (available at the Miller Library).
An example of how Seattle Public Utilities has implemented the idea on neighborhood scale.
