How to Find a Storm Drain

There are several types of storm drains. Most drains are located next to the curb and have a metal grate to prevent debris from falling in. They can be rectangular or circular. Storm drains are often stenciled with text such as:

  • Dump No Waste. Drains to Stream, Lake or Bay.
  • Only Rain Down the Drain. Puget Sound Starts Here


Safety Guidelines

  • Only clear drains next to the curb on residential streets. Watch out for traffic and consider wearing bright or reflective clothing.
  • Helpful tools for cleaning: gloves, a broom or rake, a trash grabber, a shovel or large dustpan, and a yard waste container or garbage bag to collect the debris.
  • Be careful of standing water to avoid slipping.
  • If children are helping, make sure adults are supervising.
  • Don't try to lift storm drain grates. They are very heavy and only crews are authorized to remove.
  • Let our crews handle any hazards in the catch basin. Clear surface debris only using a shovel or dustpan. Beware of using your hands, as there could be sharps in the debris.

Clear your drain only if it is safe. If the drain is still clogged after you've removed the surface debris, use our Drain Report Form or call our drainage problem hotline at (206) 386-1800 to report it.


Sign Up to Adopt a Drain

Thank you for your interest in adopting one or more of Seattle's 33,000 storm drains. By pledging to keep your drain free of leaves and debris, you are joining your neighbors in helping to protect the environment, manage stormwater, and minimize flooding.

On the map below, scroll to your neighborhood and zoom in. It will show storm drains in that area. To adopt a drain, click or tap on the storm drain and fill out the adoption form. Green storm drains are available for adoption, yellow storm drains have already been adopted, and gray storm drains are unavailable because they are on an arterial street, not owned by Seattle Public Utilities (SPU), and/or should be maintained by SPU crews.

You can help:

  • Prevent flooding in your neighborhood by keeping drains free of debris.
  • Prevent pollutants from entering streams, creeks, and Puget Sound, which protects fish and other wildlife.
  • Help the city maintain our infrastructure, especially during fall months when rain increases and falling leaves block drains.
