Rain gardens are common in many suburban and urban areas. They are large, fertile gardens that seek to collect all the rain they can to sustain vibrant plant life with little need for human intervention. Many designs include pipes and rain water collection systems or have bowl shapes to trap rain water. Their designs also help to cut down on pollution run-off and erosion of soils.
Rain gardens are specifically built with certain types of soils and plants to take advantage of water from storms and runoff. The layout of these gardens helps to filtrate the water and also impede the waters speed in order to prevent erosion and flooding. Phosphorus and nitrogen levels along with sediments are reduced as the water runs through the rain garden. Most of these gardens are built with native species to the area in order to take full advantage of the storm water passing through.
A rain garden is a planted depression near an urban area (like a driveway or walkway). Rain gardens get their name from their ability to absorb rain runoff. They give a storm’s rain water somewhere to go; it is much better for this runoff to soak into the ground instead of causing erosion or water pollution. It is best to fill a rain garden with plants native to the area.
