Designing a rain garden can help reduce stormwater runoff

Blue Flag Iris is an excellent source of early season color in a rain garden.

Taking care of stormwater is a difficult and highly-priced obstacle, particularly in the designed atmosphere of urban places this sort of as Better Columbus, where by so a lot of the environment is coated with impervious surfaces these as streets and driveways, buildings and other structures, parking lots and other difficult surfaces that prevent major rains from infiltrating the soil and recharging groundwater. 

A switching local climate that generates storms with a increased intensity of rainfall only adds to this challenge.

House owners can put in smaller rain gardens in their yards to cut down stormwater runoff from paved spots such as driveways, sidewalks, patios or from downspouts, which overflow and trigger erosion through heavy rainfall activities.

What is a rain back garden?

A rain garden is designed into a shallow despair in the ground, which traps stormwater from rainfall or snowmelt and permits the water to infiltrate the soil and recharge groundwater materials. Rain gardens are commonly planted with flowering herbaceous perennials, shrubs, grasses and even trees that thrive in moist soils and do not need frequent upkeep. Plants appropriate for rain gardens normally have deep root techniques, which assists water to infiltrate as a result of the soil and will allow the plant to thrive in periods of low soil dampness.
