Surface & Stormwater

Surface water staff manage the city's stormwater system and work with residents, businesses and property owners to reduce stormwater pollution, promote private stormwater management and protect our rivers, streams and groundwater. The City spans 20 distinct drainage basins in three different watersheds. Runoff from homes, roads and parking lots makes its way to Lake Washington, the Snohomish River and Port Gardner Bay.

Many times stormwater runoff is not treated before it is released into streams, rivers, lakes and Puget Sound. Approximately 75% of all pollution in Puget Sound comes from every day activities. There are many everyday choices that you can make to help minimize pollution in our waterways.

  1. Stormwater program
  2. Surface water comp plan

Having a National Pollutant Discharge Elimination System (NPDES) stormwater permit, allows the permit holder to discharge water into existing bodies of water (waters of the state) such as creeks, lakes, Snohomish River and Port Gardner Bay. The City maintains a Phase II Municipal Stormwater Permit coverage, which authorizes discharge from the City's storm drain system.

Stormwater Management Program (SWMP)The City’s stormwater management program document describes actions the city will take throughout 2019 to maintain compliance with the permit's stormwater management program conditions, which are designed to reduce stormwater runoff pollution to Everett's waterways.

In Everett, some stormwater discharges to water bodies and some is captured in a combined sewer system and conveyed to our wastewater treatment plant, called the Everett Water Pollution Control Facility. View our sewer webpage for information on how we clean wastewater.

  1. Using green measures

Green stormwater infrastructure (GSI)
In a natural environment, soil and plants help absorb rain. But in our urban environment, where streets, buildings, and parking lots cover the ground, rain washes over these hard surfaces resulting in erosion and flooding that can harm properties and wildlife habitat. The resulting stormwater runoff also carries sediment, oil, fertilizers and other pollutants to local rivers and streams.

Green stormwater infrastructure (GSI) uses vegetation, soils and other elements and practices to restore some of the natural processes needed to manage surface water and create healthier urban environments.

  1. Downspout disconnect
  2. Rain barrels
  3. Rain gardens
  4. Natural yard care
  5. Private stormwater maintenance

Downspout disconnection is only recommended for those in the combined system areas of Everett. Disconnecting downspouts helps reduce some of the stress heavy rainfall has on the combined system, where pipes carry both wastewater and stormwater to the wastewater treatment plant.View or download our map of the combined sewer area (PDF).

Correctly disconnecting your downspouts helps direct water away from your house to a suitable area where the runoff can spread and soak into the surrounding landscape or another designated area. 

This can be accomplished fairly easily with an elbow, pipe extension and splash block. Besides having a suitable area for water runoff, other factors must be taken into consideration before disconnecting such as:

  • Are the downspouts an adequate distance from adjacent property lines?
  • Are there assurances that the excess water will not affect neighboring properties?
  • Does your property slope towards or away from your foundation?
  • How would the water flow once it is released from downspout?

If your property does not meet minimum requirements, downspout disconnection is not recommended.
