Storm Water

The quality of water impacts your quality of life. In Woodinville (city proper), there are six drainage basins, some with salmon-bearing streams, several wetlands, Lake Leota , and State designated shoreline areas on the Sammamish River and Little Bear Creek. The City's Comprehensive Plan calls for the protection of the quality and quantity of water in waterways, wetlands, flood plains and watersheds from degradation. One way to protect these environmental amenities is to protect the City's storm water system by managing runoff, erosion, sedimentation, aquatic habitat and water quality.

Storm water (sometimes called Surface Water) is the result of rain and melted snow and ice that runs off surfaces such as rooftops, paved streets, highways and parking lots and other impervious surfaces. As the water runs off these surfaces, it picks up pollutants such as oil, fertilizers, pesticides, trash and animal waste. The water may flow directly into a local stream, wetland, lake or other waterway. Or the water may flow into the storm drain and continue through pipes until it is released untreated into a local waterway. Woodinville's storm drain system feeds in to Little Bear Creek and Sammamish River . These waterways feed into Lake Washington and Puget Sound .

Untreated storm water is generally unsafe because it contains toxic metals, organic compounds, bacteria and viruses. Residential storm water runoff may include pet waste, vehicle fluids such as oil, gas and antifreeze and other hazardous solvents. Industrial storm water runoff may result from chemical spills and washing commercial vehicles and allowing the dirty water to go directly into the storm drain system. Waste from materials and equipment used in construction can wash into the City's storm drain system.

It is a violation of City code to discharge any contaminates into the City's storm drain system or surface/ground water.
