When covered in natural vegetation, the ground soaks up most rainfall. However, as we create more impervious surfaces, much of the rainfall can’t enter the soil. Instead, water sweeps over the surface, carrying trash, oil, leaves and other pollutants into our streams and rivers.
Rain gardens are “gardens with a purpose”; they allow rain to soak into the ground naturally, reducing the amount of pollution that gets into our creeks, rivers and wetlands. Rain gardens also provide habitat for many birds and beneficial insects such as bees and butterflies.
