Storm Drain Care
Seattle Public Utilities (SPU) invites you to join a community of volunteers across the city who keep our local storm drains clear to reduce flooding and pollution, and ensure that only rain goes down the drain.
- In fall, keep leaves, sticks and debris out of the drains. Rake them in your yard before they reach the drain.
- In winter, keep snow and ice from blocking drains. Remove snow and ice from your local storm drain with a snow shovel, garden shovel, rake or other strong tool to prevent flooding or ponding.
What is a storm drain?
Storm drains can be identified by their grates and can be found on most paved surfaces. They prevent flooding in our streets by taking stormwater (rain that has hit the ground) and channeling it to underground pipes.
Most of Seattle’s storm drains empty directly to local water bodies like Lake Washington, the Duwamish River, and Puget Sound, meaning that pollutants on the road often travel untreated into the environment.

Rake your leaves
If not collected, leaves can clog storm drains and pipes, leading to street flooding. By raking your leaves and keeping them out of streets and storm drains, you can reduce ponding and flooding in your neighborhood.
To help keep storm drains clear, SPU offers its household waste customers free extra yard waste pick up in the month of November. Put fallen leaves into a paper or compostable lawn and leaf bag or a reusable container with a lid. During November collection days, SPU will collect up to 10 additional yard waste bags or containers free of charge. During all other months, extra yard waste collections are charged a fixed rate.
Please do not put leaves and other yard waste in plastic bags.
