Rain Gardens

A rain garden is a shallow garden that collects rainwater from roofs, driveways, and sidewalks. The plants and soil in the garden soak up the water and filter out pollutants. Rain gardens help prevent flooding and keep streams and rivers clean. They are also beautiful and attract butterflies and birds.

How Rain Gardens Work

When it rains, water runs off hard surfaces like roofs and parking lots. This runoff picks up pollution like oil and chemicals. A rain garden catches this runoff in a low area filled with special plants and soil. The plants' roots and the soil filter the water and allow it to soak into the ground slowly.

Building a Rain Garden

Rain gardens can be built in yards, schoolyards, and parks. They are usually placed in a low spot where water naturally flows. Native plants are the best choice because they have deep roots and do not need much care. A well-designed rain garden can absorb 30 percent more water than a regular lawn.

Fun Facts
