How Rain Gardens Enhance
2 2
Our Natural Environment
and Quality of Life
Native soils and forests of western Washington absorb, store, filter, and slowly release cool, clean
water to rivers, streams, wetlands, lakes, and coastal waters. The rich diversity of life in marine and
fresh water, as well as on land, depends on clean water to thrive.
As the region grows, native forests and soils are replaced with roads, rooftops, and other hard
surfaces. When it rains or snows, more water flows from these hard surfaces than undisturbed areas,
carrying oil, fertilizers, pesticides, sediments, and other pollutants downstream. In fact, much
of the pollution in streams, wetlands, and Puget Sound now comes from stormwater flowing off
developed areas. The added water and associated pollutants from developed lands are damaging
water resources and harming aquatic life in western Washington.
How You Can Help
You can make an important contribution by Curtis Hinman
reducing the amount of stormwater and pollutants
coming from your property and entering our region’s
waterways by installing rain gardens in your yard
and other places throughout your community. iStockphoto.com
