Debris can cause clogging of storm drains.
When storm drains (also known as catch basins) clog with leaves and/or other debris, water can no longer drain from the street. This water can then pool along streets and flood intersections and homes.
Contrary to popular belief, pet wastes, oil and other materials dumped into catch basins do not go to the wastewater treatment plant, but instead flow directly into streams and rivers. Dumping grass clippings, debris and other material into the storm drain is not only illegal, but contributes pollution to our waterways and causes localized flooding.
It is important to keep catch basins free of obstructions to prevent street flooding, property damage, and hazards to the traveling public.
How should I dispose of leaves and debris?
When you are clearing your sidewalk or driveway, please do not rake or blow the leaves from your yard into the street. One option would be to sweep, collect, and bag grass clippings and leaves. Another option is to blow grass clippings back onto the lawn where they can become a mulch and a natural fertilizer. Further, consider raking or blowing leaves/debris into a compost pile, where they can decompose.
