Rain Gardens - Inexpensive & attractive treatment of stormwater runoff

A rain garden is a shallow depression in the ground that captures runoff from your driveway or roof and allows it to soak into the ground, rather than running across roads, capturing pollutants, and delivering them to nearby lakes and stream. Rain gardens are placed between stormwater runoff sources (roofs, driveways, parking lots) and runoff destinations (storm drains, streets, lakes, streams). Plants and soil work together to absorb and filter pollutants and return cleaner water through the ground to nearby streams.

Rain gardens are an inexpensive and attractive way to improve water quality and enhance the beauty of your yard or business.

North Carolina Cooperative Extension has developed an outstanding Web site that is dedicated to all aspects of building rain gardens. The website address is http://www.bae.ncsu.edu/topic/raingarden/
