On an average day, it’s estimated that 140,000 pounds of toxic chemicals enter Puget Sound. About 75% of these toxic chemicals are carried by stormwater that runs off paved roads, driveways, rooftops, and yards into stormdrains. These stormdrains flow directly to our streams and then into Puget Sound.
According to the Washington Department of Ecology, residential areas are the largest source of this pollution.
Clear of Fallen Leaves
Our rainy season starts about the same time leaves are falling on our lawns, parking lots and streets. Properly disposing of leaves and debris helps keep storm drains clear, which prevents flooding and protects fish!
All storm drains in Redmond empty directly into streams, rivers or Lake Sammamish. Leaves and branches that wash down storm drains can dam
small streams and clog
fish spawning beds. Decomposing leaves also reduce the amount of oxygen available to fish and other aquatic organisms.
Please never sweep piles of leaves into storm drains or onto drainage grates. Leaves and branches should always be placed in yard debris containers for collection, or in a composting bin. For information about disposal options for large quantities of yard debris, call Redmond’s Recycling Program at 425-556-2832.
If you notice leaves accumulating, please sweep them clear of the storm drain or place them in your cart as part of your yard waste collection service.
