Why Plant a Rain Garden?

Rain gardens help reduce water pollution by collecting rain from roofs, driveways, or other hard surfaces and naturally absorb water into the ground.

Rain gardens are gardens that are watered by collected or pooled stormwater runoff, slowly infiltrating it into the ground along root pathways. They are typically planted with wildflowers and deep-rooted native plants, which helps infiltrate rain channeled to them from roofs, driveways, yards, and other impervious surfaces.

Rain Gardens can be placed near downspouts on homes (although away from building foundations and sewer laterals) and should be slightly depressed to hold and infiltrate stormwater runoff. 

Rain gardens offer many benefits, including: 

  • Helping protect our streams and Lake Michigan from pollution by reducing stormwater runoff.
  • Reducing the risk of flooding and drainage problems.
  • Beautifying your yard and neighborhood.
  • Providing habitat for pollinators and birds.

Downspout Disconnection

During heavy rain, every downspout on your home can send 12 gallons of water a minute to the sewer system, which increases the risk of sewer water backing up into your basement and overflowing into our rivers and lake Michigan. Disconnect your downspout and help keep excess water out of sanitary sewers and into your yard or a rain garden.
