Lawns and landscapes can contribute to water quality and quantity issues if improperly designed and managed. Through sustainable design and management, lawns and landscapes can protect water resources and provide many other environmental, economic, and social benefits.

Homeowners can help protect water from pollution and reduce excess water use by:

1. Using landscape design practices that reduce the amount of runoff water from their property such as Rain gardens, swales or rain barrels.
2. Understanding what types of pollutants can originate from their home and yard.
3. Reducing the use of these potential pollutants and/or keeping potential pollutants out of the path of runoff water.
4. Using responsible lawn and landscape care practices.

Key Points:

• Every property drains to a waterway whether or not the property is located near surface water.
• In urban areas, stormwater runoff from rain and snowmelt flows from rooftops, paved areas, and yards and is directed to storm drains. Even a light rain or the flow from a garden hose or lawn irrigation system can result in runoff.
• As runoff water flows over surfaces, it can collect and carry pollutants including soil, fertilizer, pesticides and yard waste to storm drains where it is discharged to surface water.
• Water from storm drains or storm sewers is not treated to remove pollutants.
• While the amount of pollutants originating from a residential property may be small, contaminants combine with pollutants from other home lots and from municipal and business properties. When combined, the contaminants can accumulate to amounts that cause environmental problems.
• The above is called nonpoint source pollution. It cannot be easily traced to one source or one property. Virtually everyone contributes to nonpoint source pollution of water resources.
