TAPPING NATURE'S RAIN DRAINS
Rain gardens, quite simply, are gardens that soak up rain from your roof, driveway, sidewalk or yard. They are slightly different from your typical flower garden. Rain gardens are planted with wild flowers and deep-rooted native vegetation--which helps the ground soak up more water. They are typically placed near downspouts on a home to capture water, so the runoff can gradually soak into the ground
According to the Wisconsin Department of Natural Resources, rain gardens can absorb 30 percent more water than a conventional, well manicured, lawn. By directing the water into the ground, we're protecting our rivers and lakes from pollution while cleaning stormwater at the same time.
When spring storms unleashed billions of gallons of rainfall over the Milwaukee area in 2004, Richard Marklin of Wauwatosa conducted an experiment in his front yard with what he calls "amazing results"...
"We had gushers in spring," said Marklin. Still, the engineering professor at Marquette University wanted to see firsthand how his newly planted rain garden performed when put to the test. On several occasions, he stepped out in the rain to a corner of his house where a downspout sends water from his roof into the rain garden. Not knowing if the garden would perform as he expected, Marklin says he was happy with what he saw. "It's literally like a big sponge," Marklin observed, "No standing water." His rain garden is on the downhill side of several neighboring properties, which means it collects more than just rain drops from the downspout on his home.
"So, the fear anybody has that there's going to be standing water is unfounded."
