Stormwater Management

Within the Public Works Department's Surface Water Utility Division, there is a dedicated group whose primary focus is to manage the city's stormwater systems through maintenance, programs, and policies to protect the community, wildlife, and bodies of water from pollutants.

What is stormwater management?

Stormwater is rainwater. Stormwater runoff from streets, sidewalks, and driveways flows directly into storm drains and ditches to streams, wetlands, and lakes. This runoff washes pollutants into surface waters, harming water quality and fish habitat.

The importance of stormwater management

• Prevents roads from flooding during heavy rainfall
• Protects animals and their habitat
• Protects streams, ponds, and lakes to allow for continued recreational use
• Minimizes the pollutants that come from pollution

Why do you pay utilities for stormwater management? What does it contribute to?

Renton’s drainage system is a citywide utility. All properties in Renton benefit from a robust stormwater management program and as such pay surface water utility drainage fees, which are authorized by state law. These fees fund the maintenance and cleaning of Renton’s stormwater systems; efforts to reduce stormwater pollution and improvement of water quality in creeks and rivers; and projects aimed at reducing flooding, resolving drainage issues, and restoring fish habitat.

How can you help?

While there is a dedicated team within the city to help protect our bodies of water from being polluted, it takes a whole community working together

• Follow these care tips (car washing, addressing leaks, tire pressure) to prevent the creation of pollutants.
• Clear leaves and debris from stormwater drains.
• Recycle used motor oil and dispose of household hazardous waste properly.
• Use safe, non-toxic solutions to manage plant problems and utilize natural yard care practices.
• Pick up and dispose of pet waste. It is not fertilizer and can flow into streams, rivers, and lakes causing containments in the water.
• Educate yourself! The city partners with several organizations such as the Seattle Aquarium during the fall for the Cedar River Salmon Journey, to help educate residents on the impacts and solutions for preventing toxins from entering our bodies of water. Follow this page for the latest engagement opportunities and upcoming events.
• Share this information with your family, friends, and neighbors to help the community understand why these small efforts are important and the impact they have on Renton's well-being.
