Origins of Stormwater

Stormwater is water from rain or melting snow that does not soak into the ground. It flows from rooftops, over paved areas, bare soil, and through sloped lawns. As it flows, this runoff collects and transports soil, pet manure, salt, pesticides, fertilizer, oil and grease, leaves, litter, and other potential pollutants.

You don't need a heavy rainstorm to send pollutants rushing toward streams, wetlands, lakes, and oceans. A garden hose alone can supply enough water.

How Polluted Stormwater Affects the Environment

Polluted Stormwater degrades our lakes, wetlands, and rivers. Soil clouds water and degrades the habitat for fish and water plants. Phosphorus and nitrogen promote the growth of algae, which crowds out aquatic life.

Toxic chemicals, such as antifreeze and oil from leaking cars, carelessly applied pesticides, and zinc from galvanized metal gutters and downspouts threaten the health of all aquatic life. Bacteria and parasites from pet manure can make nearby lakes and rivers unsafe for recreation. Stormwater can also be a problem closer to home. It can flow into basements and cause damage that is costly to clean up.

Working to Control Stormwater & Reduce Pollution

Our Public Works Department is focusing pollution control efforts on stormwater management in our area. Stormwater pollution is not treated the same way as sanitary sewer water. Stormwater is channeled directly from discharge pipes into our streams and rivers.

Controlling stormwater pollution is very difficult because it comes from many sources. It is carried by stormwater from every street, parking lot, sidewalk, driveway, yard, and garden.

The city has prepared "A Guide For Citizens" to educate everyone about how they can do their part to keep our streams clean.
