Stormwater Tip: Keep Leaves and Yard Waste Out of Storm Drains

Actions you take in your yard impact our sewers, streams, and rivers.

For example, leaves and grass clippings left on the ground can block and clog storm drains and sewer pipes, contributing to street flooding when it rains. Fertilizers and yard waste can also cause nutrient pollution and oxygen depletion in our streams and rivers when carried through storm drains and sewers. Not only does this hurt our waterways, it can also harm fish and wildlife. 

Help protect our water and sewer resources:  

  • Do not rake or blow leaves or grass clippings off your property into the street.
  • Place your leaves in a bag for curbside yard debris collection or compost them at home.
  • If you have a mulching lawnmower, use it to recycle leaves and their nutrients into your lawn.
  • Only apply fertilizers or pesticides if necessary and do not overapply.
  • Select slow-release and organic fertilizers, which are less likely to wash away.
  • Fertilize lawns in the fall to promote root growth and prevent nutrients washing away during spring rains.
  • Do not dump yard waste, trash, or other waste near or into storm drains.
