Reducing Stormwater Runoff to Bear Creek

In the spring of 2023, CRWC installed four rain gardens in the City of Center Line to reduce stormwater runoff to Bear Creek.

When precipitation falls and moves over impervious surfaces, such as parking lots, it can pick up pollutants and sediments and carry them into our local water systems, including rivers, lakes, and streams. This rain garden, also known as a bioretention cell, is an example of green infrastructure. Native plants and an underground chamber help capture and utilize the water, preventing it from entering the storm sewer system. Capturing water on the landscape improves water quality, recharges groundwater, reduces flood risks, and protects rivers, lakes, and streams within the Clinton River watershed.

PROJECT HIGHLIGHTS:

  • Capacity to treat up to 34,000 gallons of stormwater

  • Captures and treats 99% of all rainfall events

  • Incorporates innovative techniques for stormwater management

  • Flowering plants provide habitat for pollinators
