2025 Stormwater Management Plan

In March, the city issued a draft of the 2025 Stormwater Management Plan. Thank you for your feedback and recommendations. The final plan has been published for 2025, but feedback is accepted throughout the year to inform the 2026 plan.

The City of Renton is issued a Phase II Municipal Separate Stormwater Permit (NPDES) by the Washington State Department of Ecology (Ecology). The NPDES permit regulates discharges from the City’s storm system. Through this permit, the city is responsible for creating a Stormwater Management Program (SWMP). This program includes: 

Informing and assisting in policy and strategy development to be used as tools for protect receiving waters.
Building residents' awareness of stormwater impacts, empowering the public to change behaviors that can lead to less pollution, and providing opportunities for the public to contribute to the quality of life for the community.
Providing opportunities for the public to get involved in the development, implementation, and update of the SWMP and SMAP. 
Creating maps and documentation of the storm sewer system in the city.
Preventing and detecting illegal discharges such as dumping, sewer overflow, and spills into the storm sewer system.  
Reducing pollutants in stormwater runoff from new developments, redevelopment, and construction site activities.
Controlling pollutants in stormwater runoff from areas of existing development. 
Preventing and reducing pollutant runoff from areas that discharge to the storm sewer system.
Regulating and conducting maintenance activities to prevent or reduce pollutant runoff.

Do you see anything missing or needs to be updated? Provide you feedback on the 2025 Stormwater Management Program Plan by December 31. Review the full plan and programming.
