Leave Your Leaves or Leave ’em With Us!

November 4-December 9, various drop off sites and times. Please visit the Clean Water Services website for details.

Got leaves? Drop them off with us at one of the Clean Water Services events. We all have a role to play in keeping fall leaves from clogging up our neighborhood storm drains and streets. Bring your leaves to one or more of these convenient events, or save yourself the trip and leave your leaves in your yard. Natural compost benefits your lawn and garden, provides winter habitat for beneficial species, and protects against clogged drains and flooding.

If you plan on dropping off leaves at one of our leaf disposal events, here’s what you should know: Leaves, pine needles, and grass clippings are accepted; Bring debris loose or in a paper bag (no plastic); Please limit debris to 50 pounds per bag; Program is for residents, not commercial operations; We will also be collecting monetary and food donations for local food banks.
