New Rain Garden at Mennonite Church of Normal

This spring, work will begin on a large rain garden planting in the stormwater swale in the SW corner of the lawn at Mennonite Church of Normal. The swale is already designed to capture runoff from parking areas to allow it to slowly percolate into the soil rather than flood storm sewers. The deep-rooted, perennial native grasses and wildflowers that will comprise MCN’s first rain garden boost the effectiveness of the swale, taking up additional water and releasing it slowly into the air; as well as filtering pollutants.

The rain garden planting will increased biodiversity on the property and expand habitat for birds and butterflies. Apart from the intrinsic beauty of the plants, they will provide some reduction of dust and noise for the Residential Community. Potential opportunities for missional connections with the neighborhood and broader community include use as an outdoor learning area for Headstart and as a demonstration site for rain garden workshops like those offered by Ecology Action Center.

Sod will be removed this spring and weeds will be shallowly cultivated throughout the summer. The prairie grass and wildflower seeds will be planted in the fall to take advantage of the natural effects of winter frost; both softening the seed coat and settling the seeds into the soil. The most labor is required in the first three years after which maintenance reduces to a once-a-year mowing.
