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.
Huntsdale Subdivision Basin Retrofit
Over the last decade, construction caused a buildup of silt 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.
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.
