Program Description

The Stormwater Division is the lead in the City’s efforts to protect water quality. The division's goal is to reduce the discharge of pollutants in to the storm drain system to the Maximum Extent Practicable (MEP). The City's stormwater system is not a part of its sewer system. Therefore, stormwater enters our receiving waters untreated. Urban runoff and other “non-point source” (NPS) discharges are regulated by the 1972 Federal Clean Water Act (CWA) through the National Pollutant Discharge Elimination System (NPDES) permit program. The federal Clean Water Act mandates that the City of Eureka be issued a NPDES Phase II Permit. The Stormwater Division represents the City on stormwater and NPDES stormwater permit issues before the Regional Water Quality Control Board (RWQCB). The division also provides technical expertise and guidance to all City departments to ensure implementation and compliance with the NPDES Permit.

A requirement of the Phase II permit is to develop a Stormwater Management Plan (SWMP). The SWMP describes certain Best Management Practices (BMPs) that the City will implement in order to comply with the six Minimum Control Measures (MCMs) set up for Phase II permitees. These MCMs include but are not limited to public education and outreach, public involvement/participation, illicit discharge detection and elimination, construction site stormwater runoff control, post-construction stormwater management and pollution prevention/good housekeeping in municipal operations within the City of Eureka. These six MCMs were established to reduce the discharge of pollutants in to receiving waters to the MEP. To view the City of Eureka's SWMP, click on the PDF link below.

Stormwater Pollution Prevention: It’s Up to Us

In the City of Eureka, storm drains flow directly to local creeks, and Humboldt Bay without treatment. Stormwater pollution is a serious problem for wildlife dependent on our waterways and for the people who live near streams or the bay. Some common sources of this pollution include spilled oil, fuel, fluids from vehicles and heavy equipment, construction debris, sediment, landscaping runoff containing pesticides or weed killers, and materials such as used motor oil, antifreeze, and paint products that people pour into a street or storm drain.

The Stormwater Division is involved in educating local residents and businesses to fight storm drain pollution. We hope you will join us, by visiting the PDF links below and using the described practices.

Recycling and using recyclable products is another way to reduce stormwater runoff and pollution. The recycling process is less polluting than the process of producing products from virgin materials.
