New rain gardens at Macomb Community College’s M-TEC will reduce stormwater runoff into Clinton River watershed

State environmental grant funds ecological effort and educational components

To the casual passersby, the gardens planted today at Macomb Community College’s Michigan Technical Education Center (M-TEC)in Warren are aesthetically pleasing. However, the reality is that they are much more; they are environmentally designed rain gardens that will treat and reduce stormwater runoff into the Clinton River watershed.

The rain gardens are part of a greening project funded by a nearly $66,000 Michigan Department of Environmental Quality grant to Macomb Community College to improve water quality in the Red Run tributary. It is expected that the rain gardens will capture and naturally filtrate any rainstorm of three inches or less, thus eliminating as much as 12,000 gallons of water from entering the stormwater system.

“The positive impact these rain gardens will have on our local environment is impressive,” said James O. Sawyer, IV, president, Macomb Community College. “Macomb Community College is pleased to be able to contribute to supporting a healthy local ecosystem while also creating a relevant and tangible resource for our faculty who teach sustainability as part of their curriculum.”

Preparation for the approximate 1,200 square foot gardens began with the installation of an underdrain and the cultivation of a soil mixture that consists of sand, compost and a soil specifically designed to retain and treat stormwater.  The gardens feature three zones, based on habitat preference, ease of upkeep, color throughout the seasons and ability to develop a deep root system. The lowest elevation zone (18 inches) features plants that thrive in wet conditions, the next level of plants prefer semi-wet conditions and the top level has plants with lower wetness preference. The soil mixture, combined with the plants’ root system, will filter out oil and grease as well as capture nutrients so they don’t enter the waterway.

The project also includes educational components, with Macomb Community College faculty in the architecture, construction, civil technology and land surveying programs incorporating the rain gardens in their course curriculum. The college’s continuing education also plans to use the gardens as a living laboratory and examples of sustainable sites.
