Environmental Sustainability

Sustainable approaches to providing local government services help to ensure a higher quality of life for future generations. True to its mission, Naperville’s sustainability successes have largely been achieved through many partnerships with organizations, businesses and residents. Likewise, a willingness to pursue innovative sustainable solutions has repeatedly resulted in cost efficiencies in line with the City’s sound fiscal management philosophy.

Rain Barrels

Have you ever thought about a rain barrel to provide a free irrigation option? Rain barrels are used to capture rainwater from your roof for reuse in watering garden spaces. Rainwater is better for plants and soil because it is free from the salts, ions and fluoride found in tap water. Just as importantly, rain barrels capture water that  otherwise would run off and could harm streams and rivers.

To order a rain barrel for pick-up or delivery, visit Upcycle Products.

Spring Gardening Tips

For more information, visit The Morton Arboretum at www.mortonarb.org.

  • APRIL

    • As temperatures warm, remove winter protective covering from plants.
    • Replenish mulch around existing plants to a depth of 3 to 4 inches. Keep mulch away from trunks.
    • Fertilize trees and shrubs before new growth appears. A soil test will indicate a nutrient deficiency. Follow recommendations for fertilizer and pH adjustments.
    • Weather permitting, dig and move trees and shrubs prior to bud break.
    • Watch for insects and diseases that gave you problems last year. The sooner you detect damage, the easier it is to control.
    • Control apple scab on crabapple with a fungicide just as leaf buds begin to open. Spray should be repeated every 10 to 14 days until dry weather begins.
    • Avoid pruning oaks and elms between mid-April and October. Oak wilt and Dutch elm disease are spread by sap-feeding insects carrying the disease from tree to tree.
    • Divide and move perennials every three years to prevent them from overcrowding.
    • Deadhead spring bulbs when they are finished flowering to direct energy back into bulbs. Discard tulips that only produced large leaves and no flowers.
    • Plant a tree in celebration of Arbor Day!

Pollination Station

Pollination Station in JuneThe City of Naperville is proud to have planted a pollination station in a plot of land above the east entrance to the lower level of the Municipal Center. This garden features a variety of native plant species that can offer a habitat for butterflies and other pollinators. This demonstration garden is a way to educate our community about the benefits of alternate landscaping options and inspire community members to learn more about this type of gardening.

City Received the Governor's Sustainability Award

Governor's Sustainability Award In November 2016, the City was one of 25 public and private organizations honored with the Illinois Governor’s Sustainability Award for its Citywide environmental sustainability efforts. Praised sustainability practices included successful and ongoing completion of 46 goals in the City’s 2010 Sustainability Plan and specific projects including the Water Leak Detection Survey, the new Household Hazardous Waste Facility that opened in early 2015, the Recycling Cart Program, the Emerald Ash Borer treatment program and the City’s plans to construct a compressed natural gas (CNG) fueling station, which opened in late 2020. 

A Beautiful Yard without Pesticides

Studies show that use of lawn chemicals can have environmental ramifications, especially for children. The chemicals potentially can contaminate surface and groundwater, affect outdoor and indoor air quality, and threaten the health of pets and wildlife. Have you considered alternative approaches, such as:

  • 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.

Monarch Waystation

The monarch migration is truly one of the world's greatest natural wonders. Did you know that the monarch butterfly is in desperate need of habitats to lay its eggs? The City of Naperville would like to encourage residents to plant monarch waystations in their own backyards. If your monarch habitat meets or exceeds the general description of a Monarch Waystation set forth below, your habitat may be certified by Monarch Watch as a Monarch Waystation. You may also choose to purchase a weatherproof sign to display, identifying your habitat as an official Monarch Waystation. See the Monarch Waystation tips (PDF) for more information.
