Landscapes for Rain
Traditional stormwater management drained water away as quickly as possible. Unfortunately, this increase in volume and flow led to two key effects: flooding and stream erosion (ARC 2010). This can be reversed with green infrastructure to benefit our community's health and vitality.
Uniting Built and Natural Environments
Heartland Park uses green infrastructure to help filter stormwater runoff before it reaches the seven-acre lake. The lake and green infrastructure located in the park serves as flood control for 472 acres of drainage area. With 2,500 trees, shrubs, and flowers, these biofilters serve as an innovative way to improve water quality.
Demonstration Project: Huntsdale Subdivision Basin
Over the last decade, construction caused a build-up of silt which filled in the basin that was originally 9-foot deep. Higher water temperatures and nutrients from geese and lawn fertilizers in runoff lowered the oxygen, caused excessive algae and killed fish.
Retrofit Project Goals: Remove silt and trash, increase oxygen for aquatic life, and create rain gardens, or biofilters, upstream using native plants and soil to soak in and filter runoff and remove pollutants before it gets the basin and Spring Creek.

Native Plants & Tips for Your Yard
The source of our drinking water (local rivers) starts at your front door. Your yard can have a big impact on the quality of our local waterways. By keeping litter, chemicals and yard waste out of street gutters and storm drains, you are helping prevent stormwater pollution - since these drain directly into nearby lakes, streams or wetlands without being treated or filtered. Remember: only rain should go down storm drains.

Monarch Butterfly Habitat
Monarchs are important and beautiful pollinators for plants. Populations have declined 90% due to habitat loss and environmental stress. The Midwest is a vital breeding ground for monarch butterflies traveling to Mexico and we play a critical role in their success or decline. Learn how you can make a difference by planting native milkweed and other plants for habitat.
