At Rotary Club of Ann Arbor North Luncheon on April 25, 2019 our keynote speaker was Rotarian Scott Nelson. Scott talked about how to create a rain garden. 
Mother earth creates the rain - but we create the runoff. When rain hits the roofs, streets, and driveways of our neighborhoods, it washes pollution into the river. A rain garden captures the rain water runoff and filters it clean.
One inch of rainfall means 600 gallons of water will be captured by a typical rain garden. Captured water won't go to municipal pipes, won't add pollution to the river, and won't contribute to flooding. This water will recharge the groundwater. Before it does, it keeps the garden looking green and lush.
A rain garden is an attractive landscaping feature planted with perennial native plants. It is a bowl-shaped or saucer-shaped garden, designed to absorb storm water run-off from impervious surfaces such as roofs and parking lots. Rain gardens can be small home-owner style gardens, large complex gardens, or anywhere in between.
Last year Scott took a "Master RAIN Gardener Class"  at the Washtenaw County Water Resource Commission. Scott, earned a rain garden certificate by taking the class and building a rain garden. The class trained him to design and install rain gardens - and to serve his neighborhood as an expert.
Scott learned, about rain gardens because in front of his Church called Ann Arbor Seventh Day Adventist Church flooded with water after it rained. Scott felt if they created a rain garden the flooding would be eliminated. So in 2018 he finished the rain garden.
Scott encouraged us to come to his church and take a look at their rain garden.
