Doing garden work isn’t the first thing that comes to mind in winter months, but that is precisely what happened on Hope St. between Carlton and Benjamin! There’s a lot of planning and prep work that needs to be done before a curb-cut rain garden goes in, and folks were out in the watershed doing just that in the snow of December. Pictured below, soil borings are being examined to ensure the location of the potential rain garden has the appropriate drainage required.

Curb-cut rain gardens are an important aspect in reducing stormwater runoff in urban settings, runoff that carries pollutants such as chemicals and trash. Within our watershed, storm drains empty runoff from our city streets directly into Coldbrook Creek, which flows into the Grand River and eventually makes its way to Lake Michigan. It may seem like a small thing, but by diverting this runoff into curb-cut rain gardens throughout the watershed we are able to stem the flow of those pollutants from reaching the waterway. In addition, this also reduces erosion caused by flash flooding that often occurs in urban areas. This is all done by slowing the water down, spreading it out, and letting it soak into the ground. In curb-cut rain gardens this is facilitated by planting native plants, which send deep roots into the soil which utilize the water to grow and also stabilize the soil.
After the winter soil borings determined the soil was appropriate for curb-cut rain gardens, the actual gardens were created this past spring and summer! The pictures below show this process, from digging the water retention area, to planting the native plants, to actually cutting the curb to divert the water.



The five rain gardens on Hope Street were funded through a grant from the Michigan Department of Environment Great Lakes and Energy (EGLE). This project was a partnership between the West Michigan Environmental Action Council (WMEAC) and the Lower Grand River Organization of Watersheds (LGROW). In total, LGROW planted 25 rain gardens and conducted 101 site assessments throughout the Lower Grand River Watershed. For more information on rain gardens visit the organizations’ links above.
A big thanks to all involved! Come to Hope St. and check out the curb-cut rain gardens in action!
