Leaf Disposal and Helpful Tips

As leaves fall, storm drains can get blocked by debris, leading to localized flooding. These drains are vital for keeping streets and sidewalks clear of excess rainwater as well as maintaining stormwater quality standards. Simply clearing leaves and debris from the surface of catch basins near your property with a broom or rake can keep the drainage system functioning well.

The City has a limited number of free drop boxes available to support neighborhood clean-up events through a contract agreement with Republic Services. Neighborhoods can apply for a free drop box to help collect neighborhood leaves.
