Storm Water System Information
Storm water runoff happens when rain or snow melt flows off impervious surfaces such as roofs, driveways, sidewalks, and streets which prevent the water from naturally soaking into the ground.
Storm water flowing across hard surfaces may pick up pollutants along the way such as oil, fertilizer, chemicals, dirt, litter, and other debris. When runoff becomes polluted, it can harm the environment by flowing into Monroe’s surface water collection system. These waters eventually flow into our streams, lakes, wetlands, and the Skykomish River.
The Department of Ecology’s Storm water Management Manual for Western Washington has been adopted for reference by the Monroe City Council. The City is required by Federal Law to maintain an operating permit, which is generally referred to as the National Pollutant Discharge Elimination System permit. Collectively these documents provide the required foundation for the majority of the City’s storm water management program activities.
The National Pollutant Discharge Elimination System permit requires the City to post select documents for public review and comment. Below, you will find links to the City’s annual storm water system report, the storm water management program plan, and the quality assurance project plan.
Storm water Management Plan (SWMP) Public Comment
The Storm water Management Program is a set of actions and activities performed by the City to comply with Section S5 of the City’s Phase II Municipal Storm water Permit. The SWMP is provided as a means to inform the public of planned activities for the upcoming calendar year and is updated annually. The City of Monroe welcomes public comment on the Storm water Management Plan (PDF) throughout the year. If you have comments regarding the 2020 report or suggestions for our 2021 plan, please email Vince Bertrand.
