The City of Woodinville partners with local agencies to ensure the environment is protected.  The city’s individual efforts span a variety of environmental protection areas, including stormwater management, critical areas, tree preservation and recycling/waste reduction.

Stormwater Management

Spill Hotline: 425-489-2700

Outside regular business hours (M-Th 7:30am - 5pm; F 7:30am- 4pm) or for emergencies or hazardous spills, please call 911.
Illicit discharges, which include soaps, oils, and chemicals that run into the city's stormwater system, are prohibited by Woodinville Municipal Code 13.04.030.

Woodinville has six drainage basins that include salmon-bearing streams, wetlands,  Lake Leota, and State-designated shoreline areas on the Sammamish River and Little Bear Creek.  Woodinville is responsible for protecting its waterways, wetlands, flood plains and watersheds from degradation. The most direct way the city can protect its waterways is by correctly managing its stormwater system.  This means managing runoff, erosion, sedimentation, aquatic habitat and water quality.

Stormwater (also known as 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 (not breathable) surfaces. As 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 it 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 into Little Bear Creek and the Sammamish River. These waterways feed into Lake Washington and the Puget Sound.

Untreated storm water is generally unsafe because it contains toxic metals, organic compounds, bacteria and viruses. Residential stormwater 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 as well. It is a violation of Woodinville Municipal Code to discharge any contaminates into the city’s storm drain system or surface/ground water. Remember: only rain down the drain! Please help protect the Puget Sound.

Stormwater Management Program Plan & Annual Report

The City of Woodinville is required to comply with the Western Washington Phase II Municipal Permit. The Western Washington Phase II Municipal Permit, also known as the National Pollutant Discharge Elimination System Permit was first issued on January 17, 2007, by the Washington State Department of Ecology under the provisions of the U.S. Environmental Protection Agency's Clean Water Act. The current five-year permit went into effect on August 1, 2013. A new permit will be issued on July 1, 2019 and will become effective on August 1, 2019.

The Permit has requirements for implementation of programs to minimize the discharge of pollution from municipal stormwater systems into our streams, lakes, rivers and wetlands.

To comply with the Permit requirements the City of Woodinville develops and updates yearly a Stormwater Management Program Plan (Plan) and Annual Report. The Plan describes the City’s planned actions and activities for the year. The Annual Report describes City activities for 2018. 

Review and Comment

The City encourages public comment and participation in the development and implementation of the Plan. Feedback on the current Plan will be use to shape next year's Plan. Please provide your comments by December 31, 2019 to: or City of Woodinville 17301 133rd Avenue NE, Woodinville WA 98072 Attn: Public Works Department.

Critical Areas Protection

Woodinville uses a variety of resources to inform its efforts in protecting and restoring its critical areas for fish and wildlife.  The City’s environmental protection regulations stem from the Washington State Growth Management Act (GMA) and State Environmental Policy Act (SEPA).  These were enacted to protect critical areas such as wetlands, streams, water quality, steep slopes, habitat and fish and wildlife.

Tree Preservation

The City is committed to developing and improving the capacity of the Woodinville community to plant and care for trees in parks, along streets, and in other urban settings. Woodinville’s vision for its tree canopy is that its community urban forest is a reflection of the city’s health, well-being and livability.
Trees keep air supply fresh by absorbing carbon dioxide and producing oxygen. They improve water quality by slowing and filtering rain water as well as protecting aquifers and watersheds. Trees provide shade and shelter which reduce heating and cooling costs and protect wildlife habitat.

Recycling/Waste Reduction

The City of Woodinville's Recycling Program helps Woodinville residents and businesses conserve natural resources by providing programs for reducing, reusing and recycling waste that would otherwise end up in landfills.  Waste reduction and recycling are environmentally responsible and cost-effective methods for reducing generated waste.   For a complete list of what you can recycle in Woodinville, visit Waste Management - City of Woodinville or search specific products at the King County Solid Waste Division - What Do I Do With...? site.
