2024 DuPage River Sweep

Organized by The Conservation Foundation, the annual DuPage River Sweep is a county-wide self-coordinated stream cleanup held each spring. The purpose of the one-day event is to encourage volunteer groups to help “sweep our rivers clean” by picking up debris in and along local waterways. This year's river cleanup will be held on Saturday, May 4.

Healthy Yards and Healthy Communities

The actions we take to maintain our yards can have direct consequences for the health of our community and our rivers. These ideas and resources can help achieve a beautiful yard while also caring for the environment.

  • Plant a tree. Each year, the City hosts an Arbor Day Tree Sale, in which residents can choose from a number of container-grown species including maples, oaks and elms for use in beautifying their yards and sustaining the environment.
  • Replace turf grass with native and deep-rooted plants.
  • Collect rainwater in a rain barrel. Order your own rain barrel for pickup at The Conservation Foundation's McDonald Farm or home delivery. You can also place an order to pick up your ran barrel during the Arbor Day Tree Sale.
  • Use smart technology to water your lawn and garden only when it needs it. Learn how irrigation controllers can help you water more efficiently.
  • Consider installing a native planting pollinator garden.
  • Create a Monarch Waystation

A Beautiful Yard Without Pesticides

Studies show that use of lawn chemicals can have environmental ramifications, especially for children. These chemicals potentially can contaminate surface and groundwater, affect outdoor and indoor air quality, and threaten the health of pets and wildlife. Alternative approaches include:

  • Leave grass clippings on the lawn to act as a natural fertilizer.
  • Overseed to fill in existing bare spots in the late summer or early fall. This approach will prevent weeds from taking over these spaces in the spring.
  • Aerate your soil to facilitate healthy grass growth.
  • Keep your mower blade setting at least 2-3 inches tall to allow your grass to developer deeper, more drought-resistant roots.

Have you also considered using native plants in your landscaping? Join the many homeowners who have incorporated native plants into their landscapes to create beautiful outdoor spaces, invite birds and butterflies to their yards, reduce their use of water, fertilizers and pesticides and protect our rivers.

The Conservation Foundation’s Conservation@Home program offers free advice and ideas to help eliminate chemical use, incorporate earth-friendly landscaping and create native gardens.

No Mow May

By waiting to pull out their lawnmowers and refraining from the use of pesticides and herbicides, residents allow early flowering plants to grow, providing a critical food source for newly emerged pollinators and supporting the development of healthy urban ecosystems. 

Registered participants will be exempt from ordinances governing "weeds" and grass height for the month of May with the display of a printable No-Mow May participation sign, similar to a building permit. 

Participants can register from April 15 to May 3. Fill out the 2024 registration form for No-Mow May. (Form will be available beginning April 15.)
