What is a Rain Garden?

Rain Garden

A rain garden is a shallow, constructed depression that is planted with deep-rooted native plants & grasses. It is located to receive runoff from hard surfaces such as a roof via a downspout, a sidewalk and driveway. Rain gardens slow down the rush of water from these hard surfaces, holds the water for a short period of time and allows it to naturally infiltrate into the ground.

The Cumberland River Compact is thrilled to lead Nashville in an effort to build 300 rain gardens over the next 5 years. We will bring together our network of trusted engineers, landscape architects and nurseries to assist us in this effort. We are planning workshops, demonstration sites and more education through written publications. Check the events section of our website often for a listing of ways to become involved.


Why should I plant a Rain Garden?

A rain garden can be thought of as a personal water quality system because it filters the runoff from your roof and lawn and recharges the groundwater. A properly constructed rain garden can capture and filter more than 40,000 gallons of stormwater each year! Additional rain garden benefits include:

  • Lower maintenance garden/yard
  • An increase in beneficial insects that will help eliminate those pesky ones
  • Attracts pollinators
  • Will help reduce standing water which will in turn reduce mosquito breeding
