Installation Guidelines

  • Visit www.raingardens.org to learn about the benefits of rain gardens.
  • Locate the rain garden at least 10 feet from a foundation or basement in parrial or full sun, in a relatively flat area.
  • Size the garden to be about 15-20% of the area from which it will receive runoff (e.g. roof, lawn, parking lot) for well-drained. sandy soils. Make the rain garden larger (30-45% of the drainage area) in clayey soils.
  • Kidney, oval, or other long shapes work well, with the length about twice the width. Direct runoff into the garden's long edge via a downspout or depression.
  • Call MISS DIG at 811 or 1-800-482-7171 before you dig.
  • For sandy or silty well-drained soils, dig a shallow basin about 3-6 inches deep, making the botom level and gently sloping the edges or building a berm around the lower edge. You may want to make the basin slightly deeper for clayey soils (5-7 inches).
  • Plant native plant plugs about 12-18 inches apart and add a 2 inch layer of shredded hardwood mulch or another ground cover to suppress weeds. Using edging can help keep grass out of your garden and provide definition.
  • Water plants in the first two years until established, cut back plants in the fall or spring and divide plants and weed as needed. Visit michiganflora.net for pictures of plants in all growth stages to help with identification while weeding.
  • For assistance in situating, designing, or maintaining your rain garden, Kalamazoo Area Wild Ones offers a free site visit to your property with suggestions and advice for Wild Ones members, as well as a free yearly plant exchange. Yearly memberships start at $20-37. Visit kalamazoowildones.org for more information. Contact the Office of the Kalamazoo County Drain Commissioner (269-384-8117) for a partial refund toward a one-year membership after rain garden installation is complete.
